fix: support Anthropic-compatible endpoints for third-party providers

Three bugs prevented providers like MiniMax from using their Anthropic-compatible endpoints (e.g. api.minimax.io/anthropic): 1. _VALID_API_MODES was missing 'anthropic_messages', so explicit api_mode config was silently rejected and defaulted to chat_completions. 2. API-key provider resolution hardcoded api_mode to 'chat_completions' without checking model config or detecting Anthropic-compatible URLs. 3. run_agent.py auto-detection only recognized api.anthropic.com, not third-party endpoints using the /anthropic URL convention. Fixes: - Add 'anthropic_messages' to _VALID_API_MODES - API-key providers now check model config api_mode and auto-detect URLs ending in /anthropic - run_agent.py and fallback logic detect /anthropic URL convention - 5 new tests covering all scenarios Users can now either: - Set MINIMAX_BASE_URL=https://api.minimax.io/anthropic (auto-detected) - Set api_mode: anthropic_messages in model config (explicit) - Use custom_providers with api_mode: anthropic_messages
fix: custom provider uses config base_url and api_key over env vars (#1760 ) (#1994 )

-3. For persistent settings, use `save_config_value()` in `cli.py`
+All slash commands are defined in a central `COMMAND_REGISTRY` list of `CommandDef` objects. Every downstream consumer derives from this registry automatically:
+
+- **CLI** — `process_command()` resolves aliases via `resolve_command()`, dispatches on canonical name
+- **Gateway** — `GATEWAY_KNOWN_COMMANDS` frozenset for hook emission, `resolve_command()` for dispatch
+- **Gateway help** — `gateway_help_lines()` generates `/help` output
+- **Telegram** — `telegram_bot_commands()` generates the BotCommand menu
+- **Slack** — `slack_subcommand_map()` generates `/hermes` subcommand routing
+- **Autocomplete** — `COMMANDS` flat dict feeds `SlashCommandCompleter`
+- **CLI help** — `COMMANDS_BY_CATEGORY` dict feeds `show_help()`
+
+### Adding a Slash Command
+
+1. Add a `CommandDef` entry to `COMMAND_REGISTRY` in `hermes_cli/commands.py`:
+```python
+CommandDef("mycommand", "Description of what it does", "Session",
+           aliases=("mc",), args_hint="[arg]"),
+```
+2. Add handler in `HermesCLI.process_command()` in `cli.py`:
+```python
+elif canonical == "mycommand":
+    self._handle_mycommand(cmd_original)
+```
+3. If the command is available in the gateway, add a handler in `gateway/run.py`:
+```python
+if canonical == "mycommand":
+    return await self._handle_mycommand(event)
+```
+4. For persistent settings, use `save_config_value()` in `cli.py`
+
+**CommandDef fields:**
+- `name` — canonical name without slash (e.g. `"background"`)
+- `description` — human-readable description
+- `category` — one of `"Session"`, `"Configuration"`, `"Tools & Skills"`, `"Info"`, `"Exit"`
+- `aliases` — tuple of alternative names (e.g. `("bg",)`)
+- `args_hint` — argument placeholder shown in help (e.g. `"<prompt>"`, `"[name]"`)
+- `cli_only` — only available in the interactive CLI
+- `gateway_only` — only available in messaging platforms
+
+**Adding an alias** requires only adding it to the `aliases` tuple on the existing `CommandDef`. No other file changes needed — dispatch, help text, Telegram menu, Slack mapping, and autocomplete all update automatically.

+# Hermes Agent v0.3.0 (v2026.3.17)
+
+**Release Date:** March 17, 2026
+
+> The streaming, plugins, and provider release — unified real-time token delivery, first-class plugin architecture, rebuilt provider system with Vercel AI Gateway, native Anthropic provider, smart approvals, live Chrome CDP browser connect, ACP IDE integration, Honcho memory, voice mode, persistent shell, and 50+ bug fixes across every platform.
+
+---
+
+## ✨ Highlights
+
+- **Unified Streaming Infrastructure** — Real-time token-by-token delivery in CLI and all gateway platforms. Responses stream as they're generated instead of arriving as a block. ([#1538](https://github.com/NousResearch/hermes-agent/pull/1538))
+
+- **First-Class Plugin Architecture** — Drop Python files into `~/.hermes/plugins/` to extend Hermes with custom tools, commands, and hooks. No forking required. ([#1544](https://github.com/NousResearch/hermes-agent/pull/1544), [#1555](https://github.com/NousResearch/hermes-agent/pull/1555))
+
+- **Native Anthropic Provider** — Direct Anthropic API calls with Claude Code credential auto-discovery, OAuth PKCE flows, and native prompt caching. No OpenRouter middleman needed. ([#1097](https://github.com/NousResearch/hermes-agent/pull/1097))
+
+- **Smart Approvals + /stop Command** — Codex-inspired approval system that learns which commands are safe and remembers your preferences. `/stop` kills the current agent run immediately. ([#1543](https://github.com/NousResearch/hermes-agent/pull/1543))
+
+- **Honcho Memory Integration** — Async memory writes, configurable recall modes, session title integration, and multi-user isolation in gateway mode. By @erosika. ([#736](https://github.com/NousResearch/hermes-agent/pull/736))
+
+- **Voice Mode** — Push-to-talk in CLI, voice notes in Telegram/Discord, Discord voice channel support, and local Whisper transcription via faster-whisper. ([#1299](https://github.com/NousResearch/hermes-agent/pull/1299), [#1185](https://github.com/NousResearch/hermes-agent/pull/1185), [#1429](https://github.com/NousResearch/hermes-agent/pull/1429))
+
+- **Concurrent Tool Execution** — Multiple independent tool calls now run in parallel via ThreadPoolExecutor, significantly reducing latency for multi-tool turns. ([#1152](https://github.com/NousResearch/hermes-agent/pull/1152))
+
+- **PII Redaction** — When `privacy.redact_pii` is enabled, personally identifiable information is automatically scrubbed before sending context to LLM providers. ([#1542](https://github.com/NousResearch/hermes-agent/pull/1542))
+
+- **`/browser connect` via CDP** — Attach browser tools to a live Chrome instance through Chrome DevTools Protocol. Debug, inspect, and interact with pages you already have open. ([#1549](https://github.com/NousResearch/hermes-agent/pull/1549))
+
+- **Vercel AI Gateway Provider** — Route Hermes through Vercel's AI Gateway for access to their model catalog and infrastructure. ([#1628](https://github.com/NousResearch/hermes-agent/pull/1628))
+
+- **Centralized Provider Router** — Rebuilt provider system with `call_llm` API, unified `/model` command, auto-detect provider on model switch, and direct endpoint overrides for auxiliary/delegation clients. ([#1003](https://github.com/NousResearch/hermes-agent/pull/1003), [#1506](https://github.com/NousResearch/hermes-agent/pull/1506), [#1375](https://github.com/NousResearch/hermes-agent/pull/1375))
+
+- **ACP Server (IDE Integration)** — VS Code, Zed, and JetBrains can now connect to Hermes as an agent backend, with full slash command support. ([#1254](https://github.com/NousResearch/hermes-agent/pull/1254), [#1532](https://github.com/NousResearch/hermes-agent/pull/1532))
+
+- **Persistent Shell Mode** — Local and SSH terminal backends can maintain shell state across tool calls — cd, env vars, and aliases persist. By @alt-glitch. ([#1067](https://github.com/NousResearch/hermes-agent/pull/1067), [#1483](https://github.com/NousResearch/hermes-agent/pull/1483))
+
+- **Agentic On-Policy Distillation (OPD)** — New RL training environment for distilling agent policies, expanding the Atropos training ecosystem. ([#1149](https://github.com/NousResearch/hermes-agent/pull/1149))
+
+---

+# Pricing Accuracy Architecture
+
+Date: 2026-03-16
+
+## Goal
+
+Hermes should only show dollar costs when they are backed by an official source for the user's actual billing path.
+
+This design replaces the current static, heuristic pricing flow in:
+
+- `run_agent.py`
+- `agent/usage_pricing.py`
+- `agent/insights.py`
+- `cli.py`
+
+with a provider-aware pricing system that:
+
+- handles cache billing correctly
+- distinguishes `actual` vs `estimated` vs `included` vs `unknown`
+- reconciles post-hoc costs when providers expose authoritative billing data
+- supports direct providers, OpenRouter, subscriptions, enterprise pricing, and custom endpoints
+
+## Problems In The Current Design
+
+Current Hermes behavior has four structural issues:
+
+1. It stores only `prompt_tokens` and `completion_tokens`, which is insufficient for providers that bill cache reads and cache writes separately.
+2. It uses a static model price table and fuzzy heuristics, which can drift from current official pricing.
+3. It assumes public API list pricing matches the user's real billing path.
+4. It has no distinction between live estimates and reconciled billed cost.
+
+## Design Principles
+
+1. Normalize usage before pricing.
+2. Never fold cached tokens into plain input cost.
+3. Track certainty explicitly.
+4. Treat the billing path as part of the model identity.
+5. Prefer official machine-readable sources over scraped docs.
+6. Use post-hoc provider cost APIs when available.
+7. Show `n/a` rather than inventing precision.
+
+## High-Level Architecture
+
+The new system has four layers:
+
+1. `usage_normalization`
+   Converts raw provider usage into a canonical usage record.
+2. `pricing_source_resolution`
+   Determines the billing path, source of truth, and applicable pricing source.
+3. `cost_estimation_and_reconciliation`
+   Produces an immediate estimate when possible, then replaces or annotates it with actual billed cost later.
+4. `presentation`
+   `/usage`, `/insights`, and the status bar display cost with certainty metadata.
+
+## Canonical Usage Record
+
+Add a canonical usage model that every provider path maps into before any pricing math happens.
+
+Suggested structure:
+
+```python
+@dataclass
+class CanonicalUsage:
+    provider: str
+    billing_provider: str
+    model: str
+    billing_route: str
+
+    input_tokens: int = 0
+    output_tokens: int = 0
+    cache_read_tokens: int = 0
+    cache_write_tokens: int = 0
+    reasoning_tokens: int = 0
+    request_count: int = 1
+
+    raw_usage: dict[str, Any] | None = None
+    raw_usage_fields: dict[str, str] | None = None
+    computed_fields: set[str] | None = None
+
+    provider_request_id: str | None = None
+    provider_generation_id: str | None = None
+    provider_response_id: str | None = None
+```
+
+Rules:
+
+- `input_tokens` means non-cached input only.
+- `cache_read_tokens` and `cache_write_tokens` are never merged into `input_tokens`.
+- `output_tokens` excludes cache metrics.
+- `reasoning_tokens` is telemetry unless a provider officially bills it separately.
+
+This is the same normalization pattern used by `opencode`, extended with provenance and reconciliation ids.
+
+## Provider Normalization Rules
+
+### OpenAI Direct
+
+Source usage fields:
+
+- `prompt_tokens`
+- `completion_tokens`
+- `prompt_tokens_details.cached_tokens`
+
+Normalization:
+
+- `cache_read_tokens = cached_tokens`
+- `input_tokens = prompt_tokens - cached_tokens`
+- `cache_write_tokens = 0` unless OpenAI exposes it in the relevant route
+- `output_tokens = completion_tokens`
+
+### Anthropic Direct
+
+Source usage fields:
+
+- `input_tokens`
+- `output_tokens`
+- `cache_read_input_tokens`
+- `cache_creation_input_tokens`
+
+Normalization:
+
+- `input_tokens = input_tokens`
+- `output_tokens = output_tokens`
+- `cache_read_tokens = cache_read_input_tokens`
+- `cache_write_tokens = cache_creation_input_tokens`
+
+### OpenRouter
+
+Estimate-time usage normalization should use the response usage payload with the same rules as the underlying provider when possible.
+
+Reconciliation-time records should also store:
+
+- OpenRouter generation id
+- native token fields when available
+- `total_cost`
+- `cache_discount`
+- `upstream_inference_cost`
+- `is_byok`
+
+### Gemini / Vertex
+
+Use official Gemini or Vertex usage fields where available.
+
+If cached content tokens are exposed:
+
+- map them to `cache_read_tokens`
+
+If a route exposes no cache creation metric:
+
+- store `cache_write_tokens = 0`
+- preserve the raw usage payload for later extension
+
+### DeepSeek And Other Direct Providers
+
+Normalize only the fields that are officially exposed.
+
+If a provider does not expose cache buckets:
+
+- do not infer them unless the provider explicitly documents how to derive them
+
+### Subscription / Included-Cost Routes
+
+These still use the canonical usage model.
+
+Tokens are tracked normally. Cost depends on billing mode, not on whether usage exists.
+
+## Billing Route Model
+
+Hermes must stop keying pricing solely by `model`.
+
+Introduce a billing route descriptor:
+
+```python
+@dataclass
+class BillingRoute:
+    provider: str
+    base_url: str | None
+    model: str
+    billing_mode: str
+    organization_hint: str | None = None
+```
+
+`billing_mode` values:
+
+- `official_cost_api`
+- `official_generation_api`
+- `official_models_api`
+- `official_docs_snapshot`
+- `subscription_included`
+- `user_override`
+- `custom_contract`
+- `unknown`
+
+Examples:
+
+- OpenAI direct API with Costs API access: `official_cost_api`
+- Anthropic direct API with Usage & Cost API access: `official_cost_api`
+- OpenRouter request before reconciliation: `official_models_api`
+- OpenRouter request after generation lookup: `official_generation_api`
+- GitHub Copilot style subscription route: `subscription_included`
+- local OpenAI-compatible server: `unknown`
+- enterprise contract with configured rates: `custom_contract`
+
+## Cost Status Model
+
+Every displayed cost should have:
+
+```python
+@dataclass
+class CostResult:
+    amount_usd: Decimal | None
+    status: Literal["actual", "estimated", "included", "unknown"]
+    source: Literal[
+        "provider_cost_api",
+        "provider_generation_api",
+        "provider_models_api",
+        "official_docs_snapshot",
+        "user_override",
+        "custom_contract",
+        "none",
+    ]
+    label: str
+    fetched_at: datetime | None
+    pricing_version: str | None
+    notes: list[str]
+```
+
+Presentation rules:
+
+- `actual`: show dollar amount as final
+- `estimated`: show dollar amount with estimate labeling
+- `included`: show `included` or `$0.00 (included)` depending on UX choice
+- `unknown`: show `n/a`
+
+## Official Source Hierarchy
+
+Resolve cost using this order:
+
+1. Request-level or account-level official billed cost
+2. Official machine-readable model pricing
+3. Official docs snapshot
+4. User override or custom contract
+5. Unknown
+
+The system must never skip to a lower level if a higher-confidence source exists for the current billing route.
+
+## Provider-Specific Truth Rules
+
+### OpenAI Direct
+
+Preferred truth:
+
+1. Costs API for reconciled spend
+2. Official pricing page for live estimate
+
+### Anthropic Direct
+
+Preferred truth:
+
+1. Usage & Cost API for reconciled spend
+2. Official pricing docs for live estimate
+
+### OpenRouter
+
+Preferred truth:
+
+1. `GET /api/v1/generation` for reconciled `total_cost`
+2. `GET /api/v1/models` pricing for live estimate
+
+Do not use underlying provider public pricing as the source of truth for OpenRouter billing.
+
+### Gemini / Vertex
+
+Preferred truth:
+
+1. official billing export or billing API for reconciled spend when available for the route
+2. official pricing docs for estimate
+
+### DeepSeek
+
+Preferred truth:
+
+1. official machine-readable cost source if available in the future
+2. official pricing docs snapshot today
+
+### Subscription-Included Routes
+
+Preferred truth:
+
+1. explicit route config marking the model as included in subscription
+
+These should display `included`, not an API list-price estimate.
+
+### Custom Endpoint / Local Model
+
+Preferred truth:
+
+1. user override
+2. custom contract config
+3. unknown
+
+These should default to `unknown`.
+
+## Pricing Catalog
+
+Replace the current `MODEL_PRICING` dict with a richer pricing catalog.
+
+Suggested record:
+
+```python
+@dataclass
+class PricingEntry:
+    provider: str
+    route_pattern: str
+    model_pattern: str
+
+    input_cost_per_million: Decimal | None = None
+    output_cost_per_million: Decimal | None = None
+    cache_read_cost_per_million: Decimal | None = None
+    cache_write_cost_per_million: Decimal | None = None
+    request_cost: Decimal | None = None
+    image_cost: Decimal | None = None
+
+    source: str = "official_docs_snapshot"
+    source_url: str | None = None
+    fetched_at: datetime | None = None
+    pricing_version: str | None = None
+```
+
+The catalog should be route-aware:
+
+- `openai:gpt-5`
+- `anthropic:claude-opus-4-6`
+- `openrouter:anthropic/claude-opus-4.6`
+- `copilot:gpt-4o`
+
+This avoids conflating direct-provider billing with aggregator billing.
+
+## Pricing Sync Architecture
+
+Introduce a pricing sync subsystem instead of manually maintaining a single hardcoded table.
+
+Suggested modules:
+
+- `agent/pricing/catalog.py`
+- `agent/pricing/sources.py`
+- `agent/pricing/sync.py`
+- `agent/pricing/reconcile.py`
+- `agent/pricing/types.py`
+
+### Sync Sources
+
+- OpenRouter models API
+- official provider docs snapshots where no API exists
+- user overrides from config
+
+### Sync Output
+
+Cache pricing entries locally with:
+
+- source URL
+- fetch timestamp
+- version/hash
+- confidence/source type
+
+### Sync Frequency
+
+- startup warm cache
+- background refresh every 6 to 24 hours depending on source
+- manual `hermes pricing sync`
+
+## Reconciliation Architecture
+
+Live requests may produce only an estimate initially. Hermes should reconcile them later when a provider exposes actual billed cost.
+
+Suggested flow:
+
+1. Agent call completes.
+2. Hermes stores canonical usage plus reconciliation ids.
+3. Hermes computes an immediate estimate if a pricing source exists.
+4. A reconciliation worker fetches actual cost when supported.
+5. Session and message records are updated with `actual` cost.
+
+This can run:
+
+- inline for cheap lookups
+- asynchronously for delayed provider accounting
+
+## Persistence Changes
+
+Session storage should stop storing only aggregate prompt/completion totals.
+
+Add fields for both usage and cost certainty:
+
+- `input_tokens`
+- `output_tokens`
+- `cache_read_tokens`
+- `cache_write_tokens`
+- `reasoning_tokens`
+- `estimated_cost_usd`
+- `actual_cost_usd`
+- `cost_status`
+- `cost_source`
+- `pricing_version`
+- `billing_provider`
+- `billing_mode`
+
+If schema expansion is too large for one PR, add a new pricing events table:
+
+```text
+session_cost_events
+  id
+  session_id
+  request_id
+  provider
+  model
+  billing_mode
+  input_tokens
+  output_tokens
+  cache_read_tokens
+  cache_write_tokens
+  estimated_cost_usd
+  actual_cost_usd
+  cost_status
+  cost_source
+  pricing_version
+  created_at
+  updated_at
+```
+
+## Hermes Touchpoints
+
+### `run_agent.py`
+
+Current responsibility:
+
+- parse raw provider usage
+- update session token counters
+
+New responsibility:
+
+- build `CanonicalUsage`
+- update canonical counters
+- store reconciliation ids
+- emit usage event to pricing subsystem
+
+### `agent/usage_pricing.py`
+
+Current responsibility:
+
+- static lookup table
+- direct cost arithmetic
+
+New responsibility:
+
+- move or replace with pricing catalog facade
+- no fuzzy model-family heuristics
+- no direct pricing without billing-route context
+
+### `cli.py`
+
+Current responsibility:
+
+- compute session cost directly from prompt/completion totals
+
+New responsibility:
+
+- display `CostResult`
+- show status badges:
+  - `actual`
+  - `estimated`
+  - `included`
+  - `n/a`
+
+### `agent/insights.py`
+
+Current responsibility:
+
+- recompute historical estimates from static pricing
+
+New responsibility:
+
+- aggregate stored pricing events
+- prefer actual cost over estimate
+- surface estimates only when reconciliation is unavailable
+
+## UX Rules
+
+### Status Bar
+
+Show one of:
+
+- `$1.42`
+- `~$1.42`
+- `included`
+- `cost n/a`
+
+Where:
+
+- `$1.42` means `actual`
+- `~$1.42` means `estimated`
+- `included` means subscription-backed or explicitly zero-cost route
+- `cost n/a` means unknown
+
+### `/usage`
+
+Show:
+
+- token buckets
+- estimated cost
+- actual cost if available
+- cost status
+- pricing source
+
+### `/insights`
+
+Aggregate:
+
+- actual cost totals
+- estimated-only totals
+- unknown-cost sessions count
+- included-cost sessions count
+
+## Config And Overrides
+
+Add user-configurable pricing overrides in config:
+
+```yaml
+pricing:
+  mode: hybrid
+  sync_on_startup: true
+  sync_interval_hours: 12
+  overrides:
+    - provider: openrouter
+      model: anthropic/claude-opus-4.6
+      billing_mode: custom_contract
+      input_cost_per_million: 4.25
+      output_cost_per_million: 22.0
+      cache_read_cost_per_million: 0.5
+      cache_write_cost_per_million: 6.0
+  included_routes:
+    - provider: copilot
+      model: "*"
+    - provider: codex-subscription
+      model: "*"
+```
+
+Overrides must win over catalog defaults for the matching billing route.
+
+## Rollout Plan
+
+### Phase 1
+
+- add canonical usage model
+- split cache token buckets in `run_agent.py`
+- stop pricing cache-inflated prompt totals
+- preserve current UI with improved backend math
+
+### Phase 2
+
+- add route-aware pricing catalog
+- integrate OpenRouter models API sync
+- add `estimated` vs `included` vs `unknown`
+
+### Phase 3
+
+- add reconciliation for OpenRouter generation cost
+- add actual cost persistence
+- update `/insights` to prefer actual cost
+
+### Phase 4
+
+- add direct OpenAI and Anthropic reconciliation paths
+- add user overrides and contract pricing
+- add pricing sync CLI command
+
+## Testing Strategy
+
+Add tests for:
+
+- OpenAI cached token subtraction
+- Anthropic cache read/write separation
+- OpenRouter estimated vs actual reconciliation
+- subscription-backed models showing `included`
+- custom endpoints showing `n/a`
+- override precedence
+- stale catalog fallback behavior
+
+Current tests that assume heuristic pricing should be replaced with route-aware expectations.
+
+## Non-Goals
+
+- exact enterprise billing reconstruction without an official source or user override
+- backfilling perfect historical cost for old sessions that lack cache bucket data
+- scraping arbitrary provider web pages at request time
+
+## Recommendation
+
+Do not expand the existing `MODEL_PRICING` dict.
+
+That path cannot satisfy the product requirement. Hermes should instead migrate to:
+
+- canonical usage normalization
+- route-aware pricing sources
+- estimate-then-reconcile cost lifecycle
+- explicit certainty states in the UI
+
+This is the minimum architecture that makes the statement "Hermes pricing is backed by official sources where possible, and otherwise clearly labeled" defensible.

+description: Query Base (Ethereum L2) blockchain data with USD pricing — wallet balances, token info, transaction details, gas analysis, contract inspection, whale detection, and live network stats. Uses Base RPC + CoinGecko. No API key required.
+version: 0.1.0
+author: youssefea

+metadata:
+  hermes:
+    tags: [Base, Blockchain, Crypto, Web3, RPC, DeFi, EVM, L2, Ethereum]

+
+# Base Blockchain Skill
+
+Query Base (Ethereum L2) on-chain data enriched with USD pricing via CoinGecko.
+8 commands: wallet portfolio, token info, transactions, gas analysis,
+contract inspection, whale detection, network stats, and price lookup.
+
+No API key needed. Uses only Python standard library (urllib, json, argparse).
+
+---
+
+## When to Use
+
+- User asks for a Base wallet balance, token holdings, or portfolio value
+- User wants to inspect a specific transaction by hash
+- User wants ERC-20 token metadata, price, supply, or market cap
+- User wants to understand Base gas costs and L1 data fees
+- User wants to inspect a contract (ERC type detection, proxy resolution)
+- User wants to find large ETH transfers (whale detection)
+- User wants Base network health, gas price, or ETH price
+- User asks "what's the price of USDC/AERO/DEGEN/ETH?"
+
+---
+
+## Prerequisites
+
+The helper script uses only Python standard library (urllib, json, argparse).
+No external packages required.
+
+Pricing data comes from CoinGecko's free API (no key needed, rate-limited
+to ~10-30 requests/minute). For faster lookups, use `--no-prices` flag.
+
+---
+
+## Quick Reference
+
+RPC endpoint (default): https://mainnet.base.org
+Override: export BASE_RPC_URL=https://your-private-rpc.com
+
+Helper script path: ~/.hermes/skills/blockchain/base/scripts/base_client.py
+
+```
+python3 base_client.py wallet   <address> [--limit N] [--all] [--no-prices]
+python3 base_client.py tx       <hash>
+python3 base_client.py token    <contract_address>
+python3 base_client.py gas
+python3 base_client.py contract <address>
+python3 base_client.py whales   [--min-eth N]
+python3 base_client.py stats
+python3 base_client.py price    <contract_address_or_symbol>
+```
+
+---
+
+## Procedure
+
+### 0. Setup Check
+
+```bash
+python3 --version
+
+# Optional: set a private RPC for better rate limits
+export BASE_RPC_URL="https://mainnet.base.org"
+
+# Confirm connectivity
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py stats
+```
+
+### 1. Wallet Portfolio
+
+Get ETH balance and ERC-20 token holdings with USD values.
+Checks ~15 well-known Base tokens (USDC, WETH, AERO, DEGEN, etc.)
+via on-chain `balanceOf` calls. Tokens sorted by value, dust filtered.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py \
+  wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
+```
+
+Flags:
+- `--limit N` — show top N tokens (default: 20)
+- `--all` — show all tokens, no dust filter, no limit
+- `--no-prices` — skip CoinGecko price lookups (faster, RPC-only)
+
+Output includes: ETH balance + USD value, token list with prices sorted
+by value, dust count, total portfolio value in USD.
+
+Note: Only checks known tokens. Unknown ERC-20s are not discovered.
+Use the `token` command with a specific contract address for any token.
+
+### 2. Transaction Details
+
+Inspect a full transaction by its hash. Shows ETH value transferred,
+gas used, fee in ETH/USD, status, and decoded ERC-20/ERC-721 transfers.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py \
+  tx 0xabc123...your_tx_hash_here
+```
+
+Output: hash, block, from, to, value (ETH + USD), gas price, gas used,
+fee, status, contract creation address (if any), token transfers.
+
+### 3. Token Info
+
+Get ERC-20 token metadata: name, symbol, decimals, total supply, price,
+market cap, and contract code size.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py \
+  token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
+```
+
+Output: name, symbol, decimals, total supply, price, market cap.
+Reads name/symbol/decimals directly from the contract via eth_call.
+
+### 4. Gas Analysis
+
+Detailed gas analysis with cost estimates for common operations.
+Shows current gas price, base fee trends over 10 blocks, block
+utilization, and estimated costs for ETH transfers, ERC-20 transfers,
+and swaps.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py gas
+```
+
+Output: current gas price, base fee, block utilization, 10-block trend,
+cost estimates in ETH and USD.
+
+Note: Base is an L2 — actual transaction costs include an L1 data
+posting fee that depends on calldata size and L1 gas prices. The
+estimates shown are for L2 execution only.
+
+### 5. Contract Inspection
+
+Inspect an address: determine if it's an EOA or contract, detect
+ERC-20/ERC-721/ERC-1155 interfaces, resolve EIP-1967 proxy
+implementation addresses.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py \
+  contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
+```
+
+Output: is_contract, code size, ETH balance, detected interfaces
+(ERC-20, ERC-721, ERC-1155), ERC-20 metadata, proxy implementation
+address.
+
+### 6. Whale Detector
+
+Scan the most recent block for large ETH transfers with USD values.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py \
+  whales --min-eth 1.0
+```
+
+Note: scans the latest block only — point-in-time snapshot, not historical.
+Default threshold is 1.0 ETH (lower than Solana's default since ETH
+values are higher).
+
+### 7. Network Stats
+
+Live Base network health: latest block, chain ID, gas price, base fee,
+block utilization, transaction count, and ETH price.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py stats
+```
+
+### 8. Price Lookup
+
+Quick price check for any token by contract address or known symbol.
+
+```bash
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py price ETH
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py price USDC
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py price AERO
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py price DEGEN
+python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py price 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
+```
+
+Known symbols: ETH, WETH, USDC, cbETH, AERO, DEGEN, TOSHI, BRETT,
+WELL, wstETH, rETH, cbBTC.
+
+---
+
+## Pitfalls
+
+- **CoinGecko rate-limits** — free tier allows ~10-30 requests/minute.
+  Price lookups use 1 request per token. Use `--no-prices` for speed.
+- **Public RPC rate-limits** — Base's public RPC limits requests.
+  For production use, set BASE_RPC_URL to a private endpoint
+  (Alchemy, QuickNode, Infura).
+- **Wallet shows known tokens only** — unlike Solana, EVM chains have no
+  built-in "get all tokens" RPC. The wallet command checks ~15 popular
+  Base tokens via `balanceOf`. Unknown ERC-20s won't appear. Use the
+  `token` command for any specific contract.
+- **Token names read from contract** — if a contract doesn't implement
+  `name()` or `symbol()`, these fields may be empty. Known tokens have
+  hardcoded labels as fallback.
+- **Gas estimates are L2 only** — Base transaction costs include an L1
+  data posting fee (depends on calldata size and L1 gas prices). The gas
+  command estimates L2 execution cost only.
+- **Whale detector scans latest block only** — not historical. Results
+  vary by the moment you query. Default threshold is 1.0 ETH.
+- **Proxy detection** — only EIP-1967 proxies are detected. Other proxy
+  patterns (EIP-1167 minimal proxy, custom storage slots) are not checked.
+- **Retry on 429** — both RPC and CoinGecko calls retry up to 2 times
+  with exponential backoff on rate-limit errors.
+

+
+# Sherlock OSINT Username Search
+
+Hunt down social media accounts by username across 400+ social networks using the [Sherlock Project](https://github.com/sherlock-project/sherlock).
+
+## When to Use
+
+- User asks to find accounts associated with a username
+- User wants to check username availability across platforms
+- User is conducting OSINT or reconnaissance research
+- User asks "where is this username registered?" or similar
+
+## Requirements
+
+- Sherlock CLI installed: `pipx install sherlock-project` or `pip install sherlock-project`
+- Alternatively: Docker available (`docker run -it --rm sherlock/sherlock`)
+- Network access to query social platforms
+
+## Procedure
+
+### 1. Check if Sherlock is Installed
+
+**Before doing anything else**, verify sherlock is available:
+
+```bash
+sherlock --version
+```
+
+If the command fails:
+- Offer to install: `pipx install sherlock-project` (recommended) or `pip install sherlock-project`
+- **Do NOT** try multiple installation methods — pick one and proceed
+- If installation fails, inform the user and stop
+
+### 2. Extract Username
+
+**Extract the username directly from the user's message if clearly stated.**
+
+Examples where you should **NOT** use clarify:
+- "Find accounts for nasa" → username is `nasa`
+- "Search for johndoe123" → username is `johndoe123`
+- "Check if alice exists on social media" → username is `alice`
+- "Look up user bob on social networks" → username is `bob`
+
+**Only use clarify if:**
+- Multiple potential usernames mentioned ("search for alice or bob")
+- Ambiguous phrasing ("search for my username" without specifying)
+- No username mentioned at all ("do an OSINT search")
+
+When extracting, take the **exact** username as stated — preserve case, numbers, underscores, etc.
+
+### 3. Build Command
+
+**Default command** (use this unless user specifically requests otherwise):
+```bash
+sherlock --print-found --no-color "<username>" --timeout 90
+```
+
+**Optional flags** (only add if user explicitly requests):
+- `--nsfw` — Include NSFW sites (only if user asks)
+- `--tor` — Route through Tor (only if user asks for anonymity)
+
+**Do NOT ask about options via clarify** — just run the default search. Users can request specific options if needed.
+
+### 4. Execute Search
+
+Run via the `terminal` tool. The command typically takes 30-120 seconds depending on network conditions and site count.
+
+**Example terminal call:**
+```json
+{
+  "command": "sherlock --print-found --no-color \"target_username\"",
+  "timeout": 180
+}
+```
+
+### 5. Parse and Present Results
+
+Sherlock outputs found accounts in a simple format. Parse the output and present:
+
+1. **Summary line:** "Found X accounts for username 'Y'"
+2. **Categorized links:** Group by platform type if helpful (social, professional, forums, etc.)
+3. **Output file location:** Sherlock saves results to `<username>.txt` by default
+
+**Example output parsing:**
+```
+[+] Instagram: https://instagram.com/username
+[+] Twitter: https://twitter.com/username
+[+] GitHub: https://github.com/username
+```
+
+Present findings as clickable links when possible.
+
+## Pitfalls
+
+### No Results Found
+If Sherlock finds no accounts, this is often correct — the username may not be registered on checked platforms. Suggest:
+- Checking spelling/variation
+- Trying similar usernames with `?` wildcard: `sherlock "user?name"`
+- The user may have privacy settings or deleted accounts
+
+### Timeout Issues
+Some sites are slow or block automated requests. Use `--timeout 120` to increase wait time, or `--site` to limit scope.
+
+### Tor Configuration
+`--tor` requires Tor daemon running. If user wants anonymity but Tor isn't available, suggest:
+- Installing Tor service
+- Using `--proxy` with an alternative proxy
+
+### False Positives
+Some sites always return "found" due to their response structure. Cross-reference unexpected results with manual checks.
+
+### Rate Limiting
+Aggressive searches may trigger rate limits. For bulk username searches, add delays between calls or use `--local` with cached data.
+
+## Installation
+
+### pipx (recommended)
+```bash
+pipx install sherlock-project
+```
+
+### pip
+```bash
+pip install sherlock-project
+```
+
+### Docker
+```bash
+docker pull sherlock/sherlock
+docker run -it --rm sherlock/sherlock <username>
+```
+
+### Linux packages
+Available on Debian 13+, Ubuntu 22.10+, Homebrew, Kali, BlackArch.
+
+## Ethical Use
+
+This tool is for legitimate OSINT and research purposes only. Remind users:
+- Only search usernames they own or have permission to investigate
+- Respect platform terms of service
+- Do not use for harassment, stalking, or illegal activities
+- Consider privacy implications before sharing results
+
+## Verification
+
+After running sherlock, verify:
+1. Output lists found sites with URLs
+2. `<username>.txt` file created (default output) if using file output
+3. If `--print-found` used, output should only contain `[+]` lines for matches
+
+## Example Interaction
+
+**User:** "Can you check if the username 'johndoe123' exists on social media?"
+
+**Agent procedure:**
+1. Check `sherlock --version` (verify installed)
+2. Username provided — proceed directly
+3. Run: `sherlock --print-found --no-color "johndoe123" --timeout 90`
+4. Parse output and present links
+
+**Response format:**
+> Found 12 accounts for username 'johndoe123':
+>
+> • https://twitter.com/johndoe123
+> • https://github.com/johndoe123
+> • https://instagram.com/johndoe123
+> • [... additional links]
+>
+> Results saved to: johndoe123.txt
+
+---
+
+**User:** "Search for username 'alice' including NSFW sites"
+
+**Agent procedure:**
+1. Check sherlock installed
+2. Username + NSFW flag both provided
+3. Run: `sherlock --print-found --no-color --nsfw "alice" --timeout 90`
+4. Present results

-# Checkpoint & Rollback — Implementation Plan
-
-## Goal
-
-Automatic filesystem snapshots before destructive file operations, with user-facing rollback. The agent never sees or interacts with this — it's transparent infrastructure.
-
-## Design Principles
-
-1. **Not a tool** — the LLM never knows about it. Zero prompt tokens, zero tool schema overhead.
-2. **Once per turn** — checkpoint at most once per conversation turn (user message → agent response cycle), triggered lazily on the first file-mutating operation. Not on every write.
-3. **Opt-in via config** — disabled by default, enabled with `checkpoints: true` in config.yaml.
-4. **Works on any directory** — uses a shadow git repo completely separate from the user's project git. Works on git repos, non-git directories, anything.
-5. **User-facing rollback** — `/rollback` slash command (CLI + gateway) to list and restore checkpoints. Also `hermes rollback` CLI subcommand.
-
-## Architecture
-
-```
-~/.hermes/checkpoints/
-  {sha256(abs_dir)[:16]}/       # Shadow git repo per working directory
-    HEAD, refs/, objects/...    # Standard git internals
-    HERMES_WORKDIR              # Original dir path (for display)
-    info/exclude                # Default excludes (node_modules, .env, etc.)
-```
-
-### Core: CheckpointManager (new file: tools/checkpoint_manager.py)
-
-Adapted from PR #559's CheckpointStore. Key changes from the PR:
-
- **Not a tool** — no schema, no registry entry, no handler
- **Turn-scoped deduplication** — tracks `_checkpointed_dirs: Set[str]` per turn
- **Configurable** — reads `checkpoints` config key
- **Pruning** — keeps last N snapshots per directory (default 50), prunes on take
-
-```python
-class CheckpointManager:
-    def __init__(self, enabled: bool = False, max_snapshots: int = 50):
-        self.enabled = enabled
-        self.max_snapshots = max_snapshots
-        self._checkpointed_dirs: Set[str] = set()  # reset each turn
-
-    def new_turn(self):
-        """Call at start of each conversation turn to reset dedup."""
-        self._checkpointed_dirs.clear()
-
-    def ensure_checkpoint(self, working_dir: str, reason: str = "auto") -> None:
-        """Take a checkpoint if enabled and not already done this turn."""
-        if not self.enabled:
-            return
-        abs_dir = str(Path(working_dir).resolve())
-        if abs_dir in self._checkpointed_dirs:
-            return
-        self._checkpointed_dirs.add(abs_dir)
-        try:
-            self._take(abs_dir, reason)
-        except Exception as e:
-            logger.debug("Checkpoint failed (non-fatal): %s", e)
-
-    def list_checkpoints(self, working_dir: str) -> List[dict]:
-        """List available checkpoints for a directory."""
-        ...
-
-    def restore(self, working_dir: str, commit_hash: str) -> dict:
-        """Restore files to a checkpoint state."""
-        ...
-
-    def _take(self, working_dir: str, reason: str):
-        """Shadow git: add -A + commit. Prune if over max_snapshots."""
-        ...
-
-    def _prune(self, shadow_repo: Path):
-        """Keep only last max_snapshots commits."""
-        ...
-```
-
-### Integration Point: run_agent.py
-
-The AIAgent already owns the conversation loop. Add CheckpointManager as an instance attribute:
-
-```python
-class AIAgent:
-    def __init__(self, ...):
-        ...
-        # Checkpoint manager — reads config to determine if enabled
-        self._checkpoint_mgr = CheckpointManager(
-            enabled=config.get("checkpoints", False),
-            max_snapshots=config.get("checkpoint_max_snapshots", 50),
-        )
-```
-
-**Turn boundary** — in `run_conversation()`, call `new_turn()` at the start of each agent iteration (before processing tool calls):
-
-```python
-# Inside the main loop, before _execute_tool_calls():
-self._checkpoint_mgr.new_turn()
-```
-
-**Trigger point** — in `_execute_tool_calls()`, before dispatching file-mutating tools:
-
-```python
-# Before the handle_function_call dispatch:
-if function_name in ("write_file", "patch"):
-    # Determine working dir from the file path in the args
-    file_path = function_args.get("path", "") or function_args.get("old_string", "")
-    if file_path:
-        work_dir = str(Path(file_path).parent.resolve())
-        self._checkpoint_mgr.ensure_checkpoint(work_dir, f"before {function_name}")
-```
-
-This means:
- First `write_file` in a turn → checkpoint (fast, one `git add -A && git commit`)
- Subsequent writes in the same turn → no-op (already checkpointed)
- Next turn (new user message) → fresh checkpoint eligibility
-
-### Config
-
-Add to `DEFAULT_CONFIG` in `hermes_cli/config.py`:
-
-```python
-"checkpoints": False,          # Enable filesystem checkpoints before destructive ops
-"checkpoint_max_snapshots": 50, # Max snapshots to keep per directory
-```
-
-User enables with:
-```yaml
-# ~/.hermes/config.yaml
-checkpoints: true
-```
-
-### User-Facing Rollback
-
-**CLI slash command** — add `/rollback` to `process_command()` in `cli.py`:
-
-```
-/rollback         — List recent checkpoints for the current directory
-/rollback <hash>  — Restore files to that checkpoint
-```
-
-Shows a numbered list:
-```
-📸 Checkpoints for /home/user/project:
-  1. abc1234  2026-03-09 21:15  before write_file (3 files changed)
-  2. def5678  2026-03-09 20:42  before patch (1 file changed)
-  3. ghi9012  2026-03-09 20:30  before write_file (2 files changed)
-
-Use /rollback <number> to restore, e.g. /rollback 1
-```
-
-**Gateway slash command** — add `/rollback` to gateway/run.py with the same behavior.
-
-**CLI subcommand** — `hermes rollback` (optional, lower priority).
-
-### What Gets Excluded (not checkpointed)
-
-Same as the PR's defaults — written to the shadow repo's `info/exclude`:
-
-```
-node_modules/
-dist/
-build/
-.env
-.env.*
-__pycache__/
-*.pyc
-.DS_Store
-*.log
-.cache/
-.venv/
-.git/
-```
-
-Also respects the project's `.gitignore` if present (shadow repo can read it via `core.excludesFile`).
-
-### Safety
-
- `ensure_checkpoint()` wraps everything in try/except — a checkpoint failure never blocks the actual file operation
- Shadow repo is completely isolated — GIT_DIR + GIT_WORK_TREE env vars, never touches user's .git
- If git isn't installed, checkpoints silently disable
- Large directories: add a file count check — skip checkpoint if >50K files to avoid slowdowns
-
-## Files to Create/Modify
-
-| File | Change |
-|------|--------|
-| `tools/checkpoint_manager.py` | **NEW** — CheckpointManager class (adapted from PR #559) |
-| `run_agent.py` | Add CheckpointManager init + trigger in `_execute_tool_calls()` |
-| `hermes_cli/config.py` | Add `checkpoints` + `checkpoint_max_snapshots` to DEFAULT_CONFIG |
-| `cli.py` | Add `/rollback` slash command handler |
-| `gateway/run.py` | Add `/rollback` slash command handler |
-| `tests/tools/test_checkpoint_manager.py` | **NEW** — tests (adapted from PR #559's tests) |
-
-## What We Take From PR #559
-
- `_shadow_repo_path()` — deterministic path hashing ✅
- `_git_env()` — GIT_DIR/GIT_WORK_TREE isolation ✅
- `_run_git()` — subprocess wrapper with timeout ✅
- `_init_shadow_repo()` — shadow repo initialization ✅
- `DEFAULT_EXCLUDES` list ✅
- Test structure and patterns ✅
-
-## What We Change From PR #559
-
- **Remove tool schema/registry** — not a tool
- **Remove injection into file_operations.py and patch_parser.py** — trigger from run_agent.py instead
- **Add turn-scoped deduplication** — one checkpoint per turn, not per operation
- **Add pruning** — keep last N snapshots
- **Add config flag** — opt-in, not mandatory
- **Add /rollback command** — user-facing restore UI
- **Add file count guard** — skip huge directories
-
-## Implementation Order
-
-1. `tools/checkpoint_manager.py` — core class with take/list/restore/prune
-2. `tests/tools/test_checkpoint_manager.py` — tests
-3. `hermes_cli/config.py` — config keys

 # ASCII Video Production Pipeline

-Full production pipeline for rendering any content as colored ASCII character video.
+## Creative Standard
+
+This is visual art. ASCII characters are the medium; cinema is the standard.
+
+**Before writing a single line of code**, articulate the creative concept. What is the mood? What visual story does this tell? What makes THIS project different from every other ASCII video? The user's prompt is a starting point — interpret it with creative ambition, not literal transcription.
+
+**First-render excellence is non-negotiable.** The output must be visually striking without requiring revision rounds. If something looks generic, flat, or like "AI-generated ASCII art," it is wrong — rethink the creative concept before shipping.
+
+**Go beyond the reference vocabulary.** The effect catalogs, shader presets, and palette libraries in the references are a starting vocabulary. For every project, combine, modify, and invent new patterns. The catalog is a palette of paints — you write the painting.
+
+**Be proactively creative.** Extend the skill's vocabulary when the project calls for it. If the references don't have what the vision demands, build it. Include at least one visual moment the user didn't ask for but will appreciate — a transition, an effect, a color choice that elevates the whole piece.
+
+**Cohesive aesthetic over technical correctness.** All scenes in a video must feel connected by a unifying visual language — shared color temperature, related character palettes, consistent motion vocabulary. A technically correct video where every scene uses a random different effect is an aesthetic failure.
+
+**Dense, layered, considered.** Every frame should reward viewing. Never flat black backgrounds. Always multi-grid composition. Always per-scene variation. Always intentional color.

-## Pipeline Architecture (v2)
+## Pipeline Architecture

-Every mode follows the same 6-stage pipeline. See `references/architecture.md` for implementation details, `references/scenes.md` for scene protocol, and `references/composition.md` for multi-grid composition and tonemap.
+Every mode follows the same 6-stage pipeline:

 ```
-┌─────────┐   ┌──────────┐   ┌───────────┐   ┌──────────┐   ┌─────────┐   ┌────────┐
-│ 1.INPUT  │→│ 2.ANALYZE │→│ 3.SCENE_FN │→│ 4.TONEMAP │→│ 5.SHADE  │→│ 6.ENCODE│

-└─────────┘   └──────────┘   └───────────┘   └──────────┘   └─────────┘   └────────┘
+INPUT → ANALYZE → SCENE_FN → TONEMAP → SHADE → ENCODE
 ```

 1. **INPUT** — Load/decode source material (video frames, audio samples, images, or nothing)
 2. **ANALYZE** — Extract per-frame features (audio bands, video luminance/edges, motion vectors)
-3. **SCENE_FN** — Scene function renders directly to pixel canvas (`uint8 H,W,3`). May internally compose multiple character grids via `_render_vf()` + pixel blend modes. See `references/composition.md`
-4. **TONEMAP** — Percentile-based adaptive brightness normalization with per-scene gamma. Replaces linear brightness multipliers. See `references/composition.md` § Adaptive Tonemap
-5. **SHADE** — Apply post-processing `ShaderChain` + `FeedbackBuffer`. See `references/shaders.md`

 ### Per-Section Variation

-Never use the same config for the entire video. For each section/scene/quote:
- Choose a **different background effect** (or compose 2-3)
- Choose a **different character palette** (match the mood)
- Choose a **different color strategy** (or at minimum a different hue)
- Vary **shader intensity** (more bloom during peaks, more grain during quiet)
- Use **different particle types** if particles are active
+Never use the same config for the entire video. For each section/scene:
+- **Different background effect** (or compose 2-3)
+- **Different character palette** (match the mood)
+- **Different color strategy** (or at minimum a different hue)
+- **Vary shader intensity** (more bloom during peaks, more grain during quiet)
+- **Different particle types** if particles are active

 ### Project-Specific Invention

 For every project, invent at least one of:
 - A custom character palette matching the theme
- A custom background effect (combine/modify existing ones)
+- A custom background effect (combine/modify existing building blocks)
 - A custom color palette (discrete RGB set matching the brand/mood)
 - A custom particle character set
+- A novel scene transition or visual moment
+
+Don't just pick from the catalog. The catalog is vocabulary — you write the poem.

 ## Workflow

-### Step 1: Determine Mode and Gather Requirements
+### Step 1: Creative Vision
+
+Before any code, articulate the creative concept:
+
+- **Mood/atmosphere**: What should the viewer feel? Energetic, meditative, chaotic, elegant, ominous?
+- **Visual story**: What happens over the duration? Build tension? Transform? Dissolve?
+- **Color world**: Warm/cool? Monochrome? Neon? Earth tones? What's the dominant hue?
+- **Character texture**: Dense data? Sparse stars? Organic dots? Geometric blocks?
+- **What makes THIS different**: What's the one thing that makes this project unique?
+- **Emotional arc**: How do scenes progress? Open with energy, build to climax, resolve?
+
+Map the user's prompt to aesthetic choices. A "chill lo-fi visualizer" demands different everything from a "glitch cyberpunk data stream."
+
+### Step 2: Technical Design

-Establish with user:
- **Input source** — file path, format, duration
 - **Mode** — which of the 6 modes above
- **Sections** — time-mapped style changes (timestamps → effect names)
- **Resolution** — landscape 1920x1080 (default), portrait 1080x1920, square 1080x1080 @ 24fps; GIFs typically 640x360 @ 15fps
- **Style direction** — dense/sparse, bright/dark, chaotic/minimal, color palette
- **Text/branding** — easter eggs, overlays, credits, themed character sets
- **Output format** — MP4 (default), GIF, PNG sequence
- **Aspect ratio** — landscape (16:9), portrait (9:16 for TikTok/Reels/Stories), square (1:1 for IG feed)
-
-### Step 2: Detect Hardware and Set Quality
-
-Before building the script, detect the user's hardware and set appropriate defaults. See `references/optimization.md` § Hardware Detection.
-
-```python
-hw = detect_hardware()
-profile = quality_profile(hw, target_duration, user_quality_pref)
-log(f"Hardware: {hw['cpu_count']} cores, {hw['mem_gb']:.1f}GB RAM")
-log(f"Render: {profile['vw']}x{profile['vh']} @{profile['fps']}fps, {profile['workers']} workers")
-```
-
-Never hardcode worker counts, resolution, or CRF. Always detect and adapt.
+- **Resolution** — landscape 1920x1080 (default), portrait 1080x1920, square 1080x1080 @ 24fps
+- **Hardware detection** — auto-detect cores/RAM, set quality profile. See `references/optimization.md`
+- **Sections** — map timestamps to scene functions, each with its own effect/palette/color/shader config
+- **Output format** — MP4 (default), GIF (640x360 @ 15fps), PNG sequence

 ### Step 3: Build the Script

-Write as a single Python file. Major components:
+Single Python file. Components (with references):

-1. **Hardware detection + quality profile** — see `references/optimization.md`
-2. **Input loader** — mode-dependent; see `references/inputs.md`
-3. **Feature analyzer** — audio FFT, video luminance, or pass-through
-4. **Grid + renderer** — multi-density character grids with bitmap cache; `_render_vf()` helper for value/hue field → canvas
-5. **Character palettes** — multiple palettes chosen per project theme; see `references/architecture.md`
-6. **Color system** — HSV + discrete RGB palettes as needed; see `references/architecture.md`
-7. **Scene functions** — each returns `canvas (uint8 H,W,3)` directly. May compose multiple grids internally via pixel blend modes. See `references/scenes.md` + `references/composition.md`
-8. **Tonemap** — adaptive brightness normalization with per-scene gamma; see `references/composition.md`
-9. **Shader pipeline** — `ShaderChain` + `FeedbackBuffer` per-section config; see `references/shaders.md`
-10. **Scene table + dispatcher** — maps time ranges to scene functions + shader/feedback configs; see `references/scenes.md`
-11. **Parallel encoder** — N-worker batch clip rendering with ffmpeg pipes
+1. **Hardware detection + quality profile** — `references/optimization.md`
+2. **Input loader** — mode-dependent; `references/inputs.md`
+3. **Feature analyzer** — audio FFT, video luminance, or synthetic
+4. **Grid + renderer** — multi-density grids with bitmap cache; `references/architecture.md`
+5. **Character palettes** — multiple per project; `references/architecture.md` § Palettes
+6. **Color system** — HSV + discrete RGB + harmony generation; `references/architecture.md` § Color
+7. **Scene functions** — each returns `canvas (uint8 H,W,3)`; `references/scenes.md`
+8. **Tonemap** — adaptive brightness normalization; `references/composition.md`
+9. **Shader pipeline** — `ShaderChain` + `FeedbackBuffer`; `references/shaders.md`
+10. **Scene table + dispatcher** — time → scene function + config; `references/scenes.md`
+11. **Parallel encoder** — N-worker clip rendering with ffmpeg pipes
 12. **Main** — orchestrate full pipeline

-### Step 4: Handle Critical Bugs
+### Step 4: Quality Verification

-#### Font Cell Height (macOS Pillow)
+- **Test frames first**: render single frames at key timestamps before full render
+- **Brightness check**: `canvas.mean() > 8` for all ASCII content. If dark, lower gamma
+- **Visual coherence**: do all scenes feel like they belong to the same video?
+- **Creative vision check**: does the output match the concept from Step 1? If it looks generic, go back

-`textbbox()` returns wrong height. Use `font.getmetrics()`:
+## Critical Implementation Notes

-```python
-ascent, descent = font.getmetrics()
-cell_height = ascent + descent  # correct
-```
+### Brightness — Use `tonemap()`, Not Linear Multipliers

-#### ffmpeg Pipe Deadlock
-
-Never use `stderr=subprocess.PIPE` with long-running ffmpeg. Redirect to file:
-
-```python
-stderr_fh = open(err_path, "w")
-pipe = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.DEVNULL, stderr=stderr_fh)
-```
-
-#### Brightness — Use `tonemap()`, Not Linear Multipliers
-
-ASCII on black is inherently dark. This is the #1 visual issue. **Do NOT use linear `* N` brightness multipliers** — they clip highlights and wash out the image. Instead, use the **adaptive tonemap** function from `references/composition.md`:
+This is the #1 visual issue. ASCII on black is inherently dark. **Never use `canvas * N` multipliers** — they clip highlights. Use adaptive tonemap:

 ```python
 def tonemap(canvas, gamma=0.75):
-    """Percentile-based adaptive normalization + gamma. Replaces all brightness multipliers."""
    f = canvas.astype(np.float32)
-    lo = np.percentile(f, 1)          # black point (1st percentile)
-    hi = np.percentile(f, 99.5)       # white point (99.5th percentile)
-    if hi - lo < 1: hi = lo + 1
-    f = (f - lo) / (hi - lo)
-    f = np.clip(f, 0, 1) ** gamma     # gamma < 1 = brighter mids
+    lo, hi = np.percentile(f[::4, ::4], [1, 99.5])
+    if hi - lo < 10: hi = lo + 10
+    f = np.clip((f - lo) / (hi - lo), 0, 1) ** gamma
    return (f * 255).astype(np.uint8)
 ```

-Pipeline ordering: `scene_fn() → tonemap() → FeedbackBuffer → ShaderChain → ffmpeg`
+Pipeline: `scene_fn() → tonemap() → FeedbackBuffer → ShaderChain → ffmpeg`

-Per-scene gamma overrides for destructive effects:
- Default: `gamma=0.75`
- Solarize scenes: `gamma=0.55` (solarize darkens above-threshold pixels)
- Posterize scenes: `gamma=0.50` (quantization loses brightness range)
- Already-bright scenes: `gamma=0.85`
+Per-scene gamma: default 0.75, solarize 0.55, posterize 0.50, bright scenes 0.85. Use `screen` blend (not `overlay`) for dark layers.

-Additional brightness best practices:
- Dense animated backgrounds — never flat black, always fill the grid
- Vignette minimum clamped to 0.15 (not 0.12)
- Bloom threshold lowered to 130 (not 170) so more pixels contribute to glow
- Use `screen` blend mode (not `overlay`) when compositing dark ASCII layers — overlay squares dark values: `2 * 0.12 * 0.12 = 0.03`
+### Font Cell Height

-#### Font Compatibility
+macOS Pillow: `textbbox()` returns wrong height. Use `font.getmetrics()`: `cell_height = ascent + descent`. See `references/troubleshooting.md`.

-Not all Unicode characters render in all fonts. Validate palettes at init:
-```python
-for c in palette:
-    img = Image.new("L", (20, 20), 0)
-    ImageDraw.Draw(img).text((0, 0), c, fill=255, font=font)
-    if np.array(img).max() == 0:
-        log(f"WARNING: char '{c}' (U+{ord(c):04X}) not in font, removing from palette")
-```
+### ffmpeg Pipe Deadlock

-### Step 4b: Per-Clip Architecture (for segmented videos)
+Never `stderr=subprocess.PIPE` with long-running ffmpeg — buffer fills at 64KB and deadlocks. Redirect to file. See `references/troubleshooting.md`.

-When the video has discrete segments (quotes, scenes, chapters), render each as a separate clip file. This enables:
- Re-rendering individual clips without touching the rest (`--clip q05`)
- Faster iteration on specific sections
- Easy reordering or trimming in post
+### Font Compatibility

-```python
-segments = [
-    {"id": "intro", "start": 0.0, "end": 5.0, "type": "intro"},
-    {"id": "q00", "start": 5.0, "end": 12.0, "type": "quote", "qi": 0, ...},
-    {"id": "t00", "start": 12.0, "end": 13.5, "type": "transition", ...},
-    {"id": "outro", "start": 208.0, "end": 211.6, "type": "outro"},
-]
+Not all Unicode chars render in all fonts. Validate palettes at init — render each char, check for blank output. See `references/troubleshooting.md`.

-from concurrent.futures import ProcessPoolExecutor, as_completed
-with ProcessPoolExecutor(max_workers=hw["workers"]) as pool:
-    futures = {pool.submit(render_clip, seg, features, path): seg["id"]
-               for seg, path in clip_args}
-    for fut in as_completed(futures):
-        fut.result()
-```
+### Per-Clip Architecture

-CLI: `--clip q00 t00 q01` to re-render specific clips, `--list` to show segments, `--skip-render` to re-stitch only.
+For segmented videos (quotes, scenes, chapters), render each as a separate clip file for parallel rendering and selective re-rendering. See `references/scenes.md`.

- Effect building blocks (value fields, noise, SDFs): `effects.md`
- Shader pipeline, feedback buffer: `shaders.md`

-
-Higher-order patterns for composing scenes that feel intentional rather than random. These patterns use the existing building blocks (value fields, blend modes, shaders, feedback) but organize them with compositional intent.
-
-## Layer Hierarchy
-
-Every scene should have clear visual layers with distinct roles:
-
-| Layer | Grid | Brightness | Purpose |
-|-------|------|-----------|---------|
-| **Background** | xs or sm (dense) | 0.1–0.25 | Atmosphere, texture. Never competes with content. |
-| **Content** | md (balanced) | 0.4–0.8 | The main visual idea. Carries the scene's concept. |
-| **Accent** | lg or sm (sparse) | 0.5–1.0 (sparse coverage) | Highlights, punctuation, sparse bright points. |
-
-The background sets mood. The content layer is what the scene *is about*. The accent adds visual interest without overwhelming.
-
-```python
-def fx_example(r, f, t, S):
-    local = t
-    progress = min(local / 5.0, 1.0)
-
-    g_bg = r.get_grid("sm")
-    g_main = r.get_grid("md")
-    g_accent = r.get_grid("lg")
-
-    # --- Background: dim atmosphere ---
-    bg_val = vf_smooth_noise(g_bg, f, t * 0.3, S, octaves=2, bri=0.15)
-    # ... render bg to canvas
-
-    # --- Content: the main visual idea ---
-    content_val = vf_spiral(g_main, f, t, S, n_arms=n_arms, tightness=tightness)
-    # ... render content on top of canvas
-
-    # --- Accent: sparse highlights ---
-    accent_val = vf_noise_static(g_accent, f, t, S, density=0.05)
-    # ... render accent on top
-
-    return canvas
-```
-
-## Directional Parameter Arcs
-
-Parameters should *go somewhere* over the scene's duration — not oscillate aimlessly with `sin(t * N)`.
-
-**Bad:** `twist = 3.0 + 2.0 * math.sin(t * 0.6)` — wobbles back and forth, feels aimless.
-
-**Good:** `twist = 2.0 + progress * 5.0` — starts gentle, ends intense. The scene *builds*.
-
-Use `progress = min(local / duration, 1.0)` (0→1 over the scene) to drive directional change:
-
-| Pattern | Formula | Feel |
-|---------|---------|------|
-| Linear ramp | `progress * range` | Steady buildup |
-| Ease-out | `1 - (1 - progress) ** 2` | Fast start, gentle finish |
-| Ease-in | `progress ** 2` | Slow start, accelerating |
-| Step reveal | `np.clip((progress - 0.5) / 0.25, 0, 1)` | Nothing until 50%, then fades in |
-| Build + plateau | `min(1.0, progress * 1.5)` | Reaches full at 67%, holds |
-
-Oscillation is fine for *secondary* parameters (saturation shimmer, hue drift). But the *defining* parameter of the scene should have a direction.
-
-### Examples of Directional Arcs
-
-| Scene concept | Parameter | Arc |
-|--------------|-----------|-----|
-| Emergence | Ring radius | 0 → max (ease-out) |
-| Shatter | Voronoi cell count | 8 → 38 (linear) |
-| Descent | Tunnel speed | 2.0 → 10.0 (linear) |
-| Mandala | Shape complexity | ring → +polygon → +star → +rosette (step reveals) |
-| Crescendo | Layer count | 1 → 7 (staggered entry) |
-| Entropy | Geometry visibility | 1.0 → 0.0 (consumed) |
-
-## Scene Concepts
-
-Each scene should be built around a *visual idea*, not an effect name.
-
-**Bad:** "fx_plasma_cascade" — named after the effect. No concept.
-**Good:** "fx_emergence" — a point of light expands into a field. The name tells you *what happens*.
-
-Good scene concepts have:
-1. A **visual metaphor** (emergence, descent, collision, entropy)
-2. A **directional arc** (things change from A to B, not oscillate)
-3. **Motivated layer choices** (each layer serves the concept)
-4. **Motivated feedback** (transform direction matches the metaphor)
-
-| Concept | Metaphor | Feedback transform | Why |
-|---------|----------|-------------------|-----|
-| Emergence | Birth, expansion | zoom-out | Past frames expand outward |
-| Descent | Falling, acceleration | zoom-in | Past frames rush toward center |
-| Inferno | Rising fire | shift-up | Past frames rise with the flames |
-| Entropy | Decay, dissolution | none | Clean, no persistence — things disappear |
-| Crescendo | Accumulation | zoom + hue_shift | Everything compounds and shifts |
-
-## Compositional Techniques
-
-### Counter-Rotating Dual Systems
-
-Two instances of the same effect rotating in opposite directions create visual interference:
-
-```python
-# Primary spiral (clockwise)
-s1_val = vf_spiral(g_main, f, t * 1.5, S, n_arms=n_arms_1, tightness=tightness_1)
-
-# Counter-rotating spiral (counter-clockwise via negative time)
-s2_val = vf_spiral(g_accent, f, -t * 1.2, S, n_arms=n_arms_2, tightness=tightness_2)
-
-# Screen blend creates bright interference at crossing points
-canvas = blend_canvas(canvas_with_s1, c2, "screen", 0.7)
-```
-
-Works with spirals, vortexes, rings. The counter-rotation creates constantly shifting interference patterns.
-
-### Wave Collision
-
-Two wave fronts converging from opposite sides, meeting at a collision point:
-
-```python
-collision_phase = abs(progress - 0.5) * 2  # 1→0→1 (0 at collision)
-
-# Wave A approaches from left
-offset_a = (1 - progress) * g.cols * 0.4
-wave_a = np.sin((g.cc + offset_a) * 0.08 + t * 2) * 0.5 + 0.5
-
-# Wave B approaches from right
-offset_b = -(1 - progress) * g.cols * 0.4
-wave_b = np.sin((g.cc + offset_b) * 0.08 - t * 2) * 0.5 + 0.5
-
-# Interference peaks at collision
-combined = wave_a * 0.5 + wave_b * 0.5 + np.abs(wave_a - wave_b) * (1 - collision_phase) * 0.5
-```
-
-### Progressive Fragmentation
-
-Voronoi with cell count increasing over time — visual shattering:
-
-```python
-n_pts = int(8 + progress * 30)  # 8 cells → 38 cells
-# Pre-generate enough points, slice to n_pts
-px = base_x[:n_pts] + np.sin(t * 0.3 + np.arange(n_pts) * 0.7) * (3 + progress * 3)
-```
-
-The edge glow width can also increase with progress to emphasize the cracks.
-
-### Entropy / Consumption
-
-A clean geometric pattern being overtaken by an organic process:
-
-```python
-# Geometry fades out
-geo_val = clean_pattern * max(0.05, 1.0 - progress * 0.9)
-
-# Organic process grows in
-rd_val = vf_reaction_diffusion(g, f, t, S) * min(1.0, progress * 1.5)
-
-# Render geometry first, organic on top — organic consumes geometry
-```
-
-### Staggered Layer Entry (Crescendo)
-
-Layers enter one at a time, building to overwhelming density:
-
-```python
-def layer_strength(enter_t, ramp=1.5):
-    """0.0 until enter_t, ramps to 1.0 over ramp seconds."""
-    return max(0.0, min(1.0, (local - enter_t) / ramp))
-
-# Layer 1: always present
-s1 = layer_strength(0.0)
-# Layer 2: enters at 2s
-s2 = layer_strength(2.0)
-# Layer 3: enters at 4s
-s3 = layer_strength(4.0)
-# ... etc
-
-# Each layer uses a different effect, grid, palette, and blend mode
-# Screen blend between layers so they accumulate light
-```
-
-For a 15-second crescendo, 7 layers entering every 2 seconds works well. Use different blend modes (screen for most, add for energy, colordodge for the final wash).
-
-## Scene Ordering
-
-For a multi-scene reel or video:
- **Vary mood between adjacent scenes** — don't put two calm scenes next to each other
- **Randomize order** rather than grouping by type — prevents "effect demo" feel
- **End on the strongest scene** — crescendo or something with a clear payoff
- **Open with energy** — grab attention in the first 2 seconds

+## Combining Effects — Creative Guide
+
+The catalog above is vocabulary. Here's how to compose it into something that looks intentional.
+
+### Layering for Depth
+Every scene should have at least two layers at different grid densities:
+- **Background** (sm or xs): dense, dim texture that prevents flat black. fBM, smooth noise, or domain warp at low brightness (bri=0.15-0.25).
+- **Content** (md): the main visual — rings, voronoi, spirals, tunnel. Full brightness.
+- **Accent** (lg or xl): sparse highlights — particles, text stencil, glow pulse. Screen-blended on top.
+
+### Interesting Effect Pairs
+| Pair | Blend | Why it works |
+|------|-------|-------------|
+| fBM + voronoi edges | `screen` | Organic fills the cells, edges add structure |
+| Domain warp + plasma | `difference` | Psychedelic organic interference |
+| Tunnel + vortex | `screen` | Depth perspective + rotational energy |
+| Spiral + interference | `exclusion` | Moire patterns from different spatial frequencies |
+| Reaction-diffusion + fire | `add` | Living organic base + dynamic foreground |
+| SDF geometry + domain warp | `screen` | Clean shapes floating in organic texture |
+
+### Effects as Masks
+Any value field can be used as a mask for another effect via `mask_from_vf()`:
+- Voronoi cells masking fire (fire visible only inside cells)
+- fBM masking a solid color layer (organic color clouds)
+- SDF shapes masking a reaction-diffusion field
+- Animated iris/wipe revealing one effect over another
+
+### Inventing New Effects
+For every project, create at least one effect that isn't in the catalog:
+- **Combine two vf_* functions** with math: `np.clip(vf_fbm(...) * vf_rings(...), 0, 1)`
+- **Apply coordinate transforms** before evaluation: `vf_plasma(twisted_grid, ...)`
+- **Use one field to modulate another's parameters**: `vf_spiral(..., tightness=2 + vf_fbm(...) * 5)`
+- **Stack time offsets**: render the same field at `t` and `t - 0.5`, difference-blend for motion trails
+- **Mirror a value field** through an SDF boundary for kaleidoscopic geometry

+## Scene Design Philosophy
+
+Scenes are storytelling units, not effect demos. Every scene needs:
+- A **concept** — what is happening visually? Not "plasma + rings" but "emergence from void" or "crystallization"
+- An **arc** — how does it change over its duration? Build, decay, transform, reveal?
+- A **role** — how does it serve the larger video narrative? Opening tension, peak energy, resolution?
+
+The design patterns below provide compositional techniques. The scene examples show them in practice at increasing complexity. The protocol section covers the technical contract.
+
+Good scene design starts with the concept, then selects effects and parameters that serve it. The design patterns section shows *how* to compose layers intentionally. The examples section shows complete working scenes at every complexity level. The protocol section covers the technical contract that all scenes must follow.
+
+---
+
+## Scene Design Patterns
+
+Higher-order patterns for composing scenes that feel intentional rather than random. These patterns use the existing building blocks (value fields, blend modes, shaders, feedback) but organize them with compositional intent.
+
+## Layer Hierarchy
+
+Every scene should have clear visual layers with distinct roles:
+
+| Layer | Grid | Brightness | Purpose |
+|-------|------|-----------|---------|
+| **Background** | xs or sm (dense) | 0.1–0.25 | Atmosphere, texture. Never competes with content. |
+| **Content** | md (balanced) | 0.4–0.8 | The main visual idea. Carries the scene's concept. |
+| **Accent** | lg or sm (sparse) | 0.5–1.0 (sparse coverage) | Highlights, punctuation, sparse bright points. |
+
+The background sets mood. The content layer is what the scene *is about*. The accent adds visual interest without overwhelming.
+
+```python
+def fx_example(r, f, t, S):
+    local = t
+    progress = min(local / 5.0, 1.0)
+
+    g_bg = r.get_grid("sm")
+    g_main = r.get_grid("md")
+    g_accent = r.get_grid("lg")
+
+    # --- Background: dim atmosphere ---
+    bg_val = vf_smooth_noise(g_bg, f, t * 0.3, S, octaves=2, bri=0.15)
+    # ... render bg to canvas
+
+    # --- Content: the main visual idea ---
+    content_val = vf_spiral(g_main, f, t, S, n_arms=n_arms, tightness=tightness)
+    # ... render content on top of canvas
+
+    # --- Accent: sparse highlights ---
+    accent_val = vf_noise_static(g_accent, f, t, S, density=0.05)
+    # ... render accent on top
+
+    return canvas
+```
+
+## Directional Parameter Arcs
+
+Parameters should *go somewhere* over the scene's duration — not oscillate aimlessly with `sin(t * N)`.
+
+**Bad:** `twist = 3.0 + 2.0 * math.sin(t * 0.6)` — wobbles back and forth, feels aimless.
+
+**Good:** `twist = 2.0 + progress * 5.0` — starts gentle, ends intense. The scene *builds*.
+
+Use `progress = min(local / duration, 1.0)` (0→1 over the scene) to drive directional change:
+
+| Pattern | Formula | Feel |
+|---------|---------|------|
+| Linear ramp | `progress * range` | Steady buildup |
+| Ease-out | `1 - (1 - progress) ** 2` | Fast start, gentle finish |
+| Ease-in | `progress ** 2` | Slow start, accelerating |
+| Step reveal | `np.clip((progress - 0.5) / 0.25, 0, 1)` | Nothing until 50%, then fades in |
+| Build + plateau | `min(1.0, progress * 1.5)` | Reaches full at 67%, holds |
+
+Oscillation is fine for *secondary* parameters (saturation shimmer, hue drift). But the *defining* parameter of the scene should have a direction.
+
+### Examples of Directional Arcs
+
+| Scene concept | Parameter | Arc |
+|--------------|-----------|-----|
+| Emergence | Ring radius | 0 → max (ease-out) |
+| Shatter | Voronoi cell count | 8 → 38 (linear) |
+| Descent | Tunnel speed | 2.0 → 10.0 (linear) |
+| Mandala | Shape complexity | ring → +polygon → +star → +rosette (step reveals) |
+| Crescendo | Layer count | 1 → 7 (staggered entry) |
+| Entropy | Geometry visibility | 1.0 → 0.0 (consumed) |
+
+## Scene Concepts
+
+Each scene should be built around a *visual idea*, not an effect name.
+
+**Bad:** "fx_plasma_cascade" — named after the effect. No concept.
+**Good:** "fx_emergence" — a point of light expands into a field. The name tells you *what happens*.
+
+Good scene concepts have:
+1. A **visual metaphor** (emergence, descent, collision, entropy)
+2. A **directional arc** (things change from A to B, not oscillate)
+3. **Motivated layer choices** (each layer serves the concept)
+4. **Motivated feedback** (transform direction matches the metaphor)
+
+| Concept | Metaphor | Feedback transform | Why |
+|---------|----------|-------------------|-----|
+| Emergence | Birth, expansion | zoom-out | Past frames expand outward |
+| Descent | Falling, acceleration | zoom-in | Past frames rush toward center |
+| Inferno | Rising fire | shift-up | Past frames rise with the flames |
+| Entropy | Decay, dissolution | none | Clean, no persistence — things disappear |
+| Crescendo | Accumulation | zoom + hue_shift | Everything compounds and shifts |
+
+## Compositional Techniques
+
+### Counter-Rotating Dual Systems
+
+Two instances of the same effect rotating in opposite directions create visual interference:
+
+```python
+# Primary spiral (clockwise)
+s1_val = vf_spiral(g_main, f, t * 1.5, S, n_arms=n_arms_1, tightness=tightness_1)
+
+# Counter-rotating spiral (counter-clockwise via negative time)
+s2_val = vf_spiral(g_accent, f, -t * 1.2, S, n_arms=n_arms_2, tightness=tightness_2)
+
+# Screen blend creates bright interference at crossing points
+canvas = blend_canvas(canvas_with_s1, c2, "screen", 0.7)
+```
+
+Works with spirals, vortexes, rings. The counter-rotation creates constantly shifting interference patterns.
+
+### Wave Collision
+
+Two wave fronts converging from opposite sides, meeting at a collision point:
+
+```python
+collision_phase = abs(progress - 0.5) * 2  # 1→0→1 (0 at collision)
+
+# Wave A approaches from left
+offset_a = (1 - progress) * g.cols * 0.4
+wave_a = np.sin((g.cc + offset_a) * 0.08 + t * 2) * 0.5 + 0.5
+
+# Wave B approaches from right
+offset_b = -(1 - progress) * g.cols * 0.4
+wave_b = np.sin((g.cc + offset_b) * 0.08 - t * 2) * 0.5 + 0.5
+
+# Interference peaks at collision
+combined = wave_a * 0.5 + wave_b * 0.5 + np.abs(wave_a - wave_b) * (1 - collision_phase) * 0.5
+```
+
+### Progressive Fragmentation
+
+Voronoi with cell count increasing over time — visual shattering:
+
+```python
+n_pts = int(8 + progress * 30)  # 8 cells → 38 cells
+# Pre-generate enough points, slice to n_pts
+px = base_x[:n_pts] + np.sin(t * 0.3 + np.arange(n_pts) * 0.7) * (3 + progress * 3)
+```
+
+The edge glow width can also increase with progress to emphasize the cracks.
+
+### Entropy / Consumption
+
+A clean geometric pattern being overtaken by an organic process:
+
+```python
+# Geometry fades out
+geo_val = clean_pattern * max(0.05, 1.0 - progress * 0.9)
+
+# Organic process grows in
+rd_val = vf_reaction_diffusion(g, f, t, S) * min(1.0, progress * 1.5)
+
+# Render geometry first, organic on top — organic consumes geometry
+```
+
+### Staggered Layer Entry (Crescendo)
+
+Layers enter one at a time, building to overwhelming density:
+
+```python
+def layer_strength(enter_t, ramp=1.5):
+    """0.0 until enter_t, ramps to 1.0 over ramp seconds."""
+    return max(0.0, min(1.0, (local - enter_t) / ramp))
+
+# Layer 1: always present
+s1 = layer_strength(0.0)
+# Layer 2: enters at 2s
+s2 = layer_strength(2.0)
+# Layer 3: enters at 4s
+s3 = layer_strength(4.0)
+# ... etc
+
+# Each layer uses a different effect, grid, palette, and blend mode
+# Screen blend between layers so they accumulate light
+```
+
+For a 15-second crescendo, 7 layers entering every 2 seconds works well. Use different blend modes (screen for most, add for energy, colordodge for the final wash).
+
+## Scene Ordering
+
+For a multi-scene reel or video:
+- **Vary mood between adjacent scenes** — don't put two calm scenes next to each other
+- **Randomize order** rather than grouping by type — prevents "effect demo" feel
+- **End on the strongest scene** — crescendo or something with a clear payoff
+- **Open with energy** — grab attention in the first 2 seconds
+
+---
+
+## Scene Protocol

 Scenes are the top-level creative unit. Each scene is a time-bounded segment with its own effect function, shader chain, feedback configuration, and tone-mapping gamma.

+## Brightness Best Practices
+
+- Dense animated backgrounds — never flat black, always fill the grid
+- Vignette minimum clamped to 0.15 (not 0.12)
+- Bloom threshold 130 (not 170) so more pixels contribute to glow
+- Use `screen` blend mode (not `overlay`) for dark ASCII layers — overlay squares dark values: `2 * 0.12 * 0.12 = 0.03`
+- FeedbackBuffer decay minimum 0.5 — below that, feedback disappears too fast to see
+- Value field floor: `vf * 0.8 + 0.05` ensures no cell is truly zero
+- Per-scene gamma overrides: default 0.75, solarize 0.55, posterize 0.50, bright scenes 0.85
+- Test frames early: render single frames at key timestamps before committing to full render
+
+**Quick checklist before full render:**
+1. Render 3 test frames (start, middle, end)
+2. Check `canvas.mean() > 8` after tonemap
+3. Check no scene is visually flat black
+4. Verify per-section variation (different bg/palette/color per scene)
+5. Confirm shader chain includes bloom (threshold 130)
+6. Confirm vignette strength ≤ 0.25

+# Hermes Agent Setup & Configuration
+
+Use this skill when a user asks about configuring Hermes, enabling features, setting up voice, managing tools/skills, or troubleshooting.
+
+## Key Paths
+
+- Config: `~/.hermes/config.yaml`
+- API keys: `~/.hermes/.env`
+- Skills: `~/.hermes/skills/`
+- Hermes install: `~/.hermes/hermes-agent/`
+- Venv: `~/.hermes/hermes-agent/.venv/` (or `venv/`)
+
+## CLI Overview
+
+Hermes is used via the `hermes` command (or `python -m hermes_cli.main` from the repo).
+
+### Core commands:
+
+```
+hermes                          Interactive chat (default)
+hermes chat -q "question"       Single query, then exit
+hermes chat -m MODEL            Chat with a specific model
+hermes -c                       Resume most recent session
+hermes -c "project name"        Resume session by name
+hermes --resume SESSION_ID      Resume by exact ID
+hermes -w                       Isolated git worktree mode
+hermes -s skill1,skill2         Preload skills for the session
+hermes --yolo                   Skip dangerous command approval
+```
+
+### Configuration & setup:
+
+```
+hermes setup                    Interactive setup wizard (provider, API keys, model)
+hermes model                    Interactive model/provider selection
+hermes config                   View current configuration
+hermes config edit              Open config.yaml in $EDITOR
+hermes config set KEY VALUE     Set a config value directly
+hermes login                    Authenticate with a provider
+hermes logout                   Clear stored auth
+hermes doctor                   Check configuration and dependencies
+```
+
+### Tools & skills:
+
+```
+hermes tools                    Interactive tool enable/disable per platform
+hermes skills list              List installed skills
+hermes skills search QUERY      Search the skills hub
+hermes skills install NAME      Install a skill from the hub
+hermes skills config            Enable/disable skills per platform
+```
+
+### Gateway (messaging platforms):
+
+```
+hermes gateway run              Start the messaging gateway
+hermes gateway install          Install gateway as background service
+hermes gateway status           Check gateway status
+```
+
+### Session management:
+
+```
+hermes sessions list            List past sessions
+hermes sessions browse          Interactive session picker
+hermes sessions rename ID TITLE Rename a session
+hermes sessions export ID       Export session as markdown
+hermes sessions prune           Clean up old sessions
+```
+
+### Other:
+
+```
+hermes status                   Show status of all components
+hermes cron list                List cron jobs
+hermes insights                 Usage analytics
+hermes update                   Update to latest version
+hermes pairing                  Manage DM authorization codes
+```
+
+## Setup Wizard (`hermes setup`)
+
+The interactive setup wizard walks through:
+1. **Provider selection** — OpenRouter, Anthropic, OpenAI, Google, DeepSeek, and many more
+2. **API key entry** — stores securely in the env file
+3. **Model selection** — picks from available models for the chosen provider
+4. **Basic settings** — reasoning effort, tool preferences
+
+Run it from terminal:
+```bash
+cd ~/.hermes/hermes-agent
+source .venv/bin/activate
+python -m hermes_cli.main setup
+```
+
+To change just the model/provider later: `hermes model`
+
+## Skills Configuration (`hermes skills`)
+
+Skills are reusable instruction sets that extend what Hermes can do.
+
+### Managing skills:
+
+```bash
+hermes skills list              # Show installed skills
+hermes skills search "docker"   # Search the hub
+hermes skills install NAME      # Install from hub
+hermes skills config            # Enable/disable per platform
+```
+
+### Per-platform skill control:
+
+`hermes skills config` opens an interactive UI where you can enable or disable specific skills for each platform (cli, telegram, discord, etc.). Disabled skills won't appear in the agent's available skills list for that platform.
+
+### Loading skills in a session:
+
+- CLI: `hermes -s skill-name` or `hermes -s skill1,skill2`
+- Chat: `/skill skill-name`
+- Gateway: type `/skill skill-name` in any chat
+
+## Voice Messages (STT)
+
+Voice messages from Telegram/Discord/WhatsApp/Slack/Signal are auto-transcribed when an STT provider is available.
+
+### Provider priority (auto-detected):
+1. **Local faster-whisper** — free, no API key, runs on CPU/GPU
+2. **Groq Whisper** — free tier, needs GROQ_API_KEY
+3. **OpenAI Whisper** — paid, needs VOICE_TOOLS_OPENAI_KEY
+
+### Setup local STT (recommended):
+
+```bash
+cd ~/.hermes/hermes-agent
+source .venv/bin/activate  # or: source venv/bin/activate
+pip install faster-whisper
+```
+
+Add to config.yaml under the `stt:` section:
+```yaml
+stt:
+  enabled: true
+  provider: local
+  local:
+    model: base  # Options: tiny, base, small, medium, large-v3
+```
+
+Model downloads automatically on first use (~150 MB for base).
+
+### Setup Groq STT (free cloud):
+
+1. Get free key from https://console.groq.com
+2. Add GROQ_API_KEY to the env file
+3. Set provider to groq in config.yaml stt section
+
+### Verify STT:
+
+After config changes, restart the gateway (send /restart in chat, or restart `hermes gateway run`). Then send a voice message.
+
+## Voice Replies (TTS)
+
+Hermes can reply with voice when users send voice messages.
+
+### TTS providers (set API key in env file):
+
+| Provider | Env var | Free? |
+|----------|---------|-------|
+| ElevenLabs | ELEVENLABS_API_KEY | Free tier |
+| OpenAI | VOICE_TOOLS_OPENAI_KEY | Paid |
+| Kokoro (local) | None needed | Free |
+| Fish Audio | FISH_AUDIO_API_KEY | Free tier |
+
+### Voice commands (in any chat):
+- `/voice on` — voice reply to voice messages only
+- `/voice tts` — voice reply to all messages
+- `/voice off` — text only (default)
+
+## Enabling/Disabling Tools (`hermes tools`)
+
+### Interactive tool config:
+
+```bash
+cd ~/.hermes/hermes-agent
+source .venv/bin/activate
+python -m hermes_cli.main tools
+```
+
+This opens a curses UI to enable/disable toolsets per platform (cli, telegram, discord, slack, etc.).
+
+### After changing tools:
+
+Use `/reset` in the chat to start a fresh session with the new toolset. Tool changes do NOT take effect mid-conversation (this preserves prompt caching and avoids cost spikes).
+
+### Common toolsets:
+
+| Toolset | What it provides |
+|---------|-----------------|
+| terminal | Shell command execution |
+| file | File read/write/search/patch |
+| web | Web search and extraction |
+| browser | Browser automation (needs Browserbase) |
+| image_gen | AI image generation |
+| mcp | MCP server connections |
+| voice | Text-to-speech output |
+| cronjob | Scheduled tasks |
+
+## Installing Dependencies
+
+Some tools need extra packages:
+
+```bash
+cd ~/.hermes/hermes-agent && source .venv/bin/activate
+
+pip install faster-whisper    # Local STT (voice transcription)
+pip install browserbase       # Browser automation
+pip install mcp               # MCP server connections
+```
+
+## Config File Reference
+
+The main config file is `~/.hermes/config.yaml`. Key sections:
+
+```yaml
+# Model and provider
+model:
+  default: anthropic/claude-opus-4.6
+  provider: openrouter
+
+# Agent behavior
+agent:
+  max_turns: 90
+  reasoning_effort: high    # xhigh, high, medium, low, minimal, none

+## Troubleshooting
+
+### Voice messages not working
+1. Check stt.enabled is true in config.yaml
+2. Check a provider is available (faster-whisper installed, or API key set)
+3. Restart gateway after config changes (/restart)
+
+### Tool not available
+1. Run `hermes tools` to check if the toolset is enabled for your platform
+2. Some tools need env vars — check the env file
+3. Use /reset after enabling tools
+
+### Model/provider issues
+1. Run `hermes doctor` to check configuration
+2. Run `hermes login` to re-authenticate
+3. Check the env file has the right API key
+
+### Changes not taking effect
+- Gateway: /reset for tool changes, /restart for config changes
+- CLI: start a new session
+
+### Skills not showing up
+1. Check `hermes skills list` shows the skill
+2. Check `hermes skills config` has it enabled for your platform
+3. Load explicitly with `/skill name` or `hermes -s name`

+
+# inference.sh CLI
+
+Run 150+ AI apps in the cloud with a simple CLI. No GPU required.
+
+All commands use the **terminal tool** to run `infsh` commands.
+
+## When to Use
+
+- User asks to generate images (FLUX, Reve, Seedream, Grok, Gemini image)
+- User asks to generate video (Veo, Wan, Seedance, OmniHuman)
+- User asks about inference.sh or infsh
+- User wants to run AI apps without managing individual provider APIs
+- User asks for AI-powered search (Tavily, Exa)
+- User needs avatar/lipsync generation
+
+## Prerequisites
+
+The `infsh` CLI must be installed and authenticated. Check with:
+
+```bash
+infsh me
+```
+
+If not installed:
+
+```bash
+curl -fsSL https://cli.inference.sh | sh
+infsh login
+```
+
+See `references/authentication.md` for full setup details.
+
+## Workflow
+
+### 1. Always Search First
+
+Never guess app names — always search to find the correct app ID:
+
+```bash
+infsh app list --search flux
+infsh app list --search video
+infsh app list --search image
+```
+
+### 2. Run an App
+
+Use the exact app ID from the search results. Always use `--json` for machine-readable output:
+
+```bash
+infsh app run <app-id> --input '{"prompt": "your prompt here"}' --json
+```
+
+### 3. Parse the Output
+
+The JSON output contains URLs to generated media. Present these to the user with `MEDIA:<url>` for inline display.
+
+## Common Commands
+
+### Image Generation
+
+```bash
+# Search for image apps
+infsh app list --search image
+
+# FLUX Dev with LoRA
+infsh app run falai/flux-dev-lora --input '{"prompt": "sunset over mountains", "num_images": 1}' --json
+
+# Gemini image generation
+infsh app run google/gemini-2-5-flash-image --input '{"prompt": "futuristic city", "num_images": 1}' --json
+
+# Seedream (ByteDance)
+infsh app run bytedance/seedream-5-lite --input '{"prompt": "nature scene"}' --json
+
+# Grok Imagine (xAI)
+infsh app run xai/grok-imagine-image --input '{"prompt": "abstract art"}' --json
+```
+
+### Video Generation
+
+```bash
+# Search for video apps
+infsh app list --search video
+
+# Veo 3.1 (Google)
+infsh app run google/veo-3-1-fast --input '{"prompt": "drone shot of coastline"}' --json
+
+# Seedance (ByteDance)
+infsh app run bytedance/seedance-1-5-pro --input '{"prompt": "dancing figure", "resolution": "1080p"}' --json
+
+# Wan 2.5
+infsh app run falai/wan-2-5 --input '{"prompt": "person walking through city"}' --json
+```
+
+### Local File Uploads
+
+The CLI automatically uploads local files when you provide a path:
+
+```bash
+# Upscale a local image
+infsh app run falai/topaz-image-upscaler --input '{"image": "/path/to/photo.jpg", "upscale_factor": 2}' --json
+
+# Image-to-video from local file
+infsh app run falai/wan-2-5-i2v --input '{"image": "/path/to/image.png", "prompt": "make it move"}' --json
+
+# Avatar with audio
+infsh app run bytedance/omnihuman-1-5 --input '{"audio": "/path/to/audio.mp3", "image": "/path/to/face.jpg"}' --json
+```
+
+### Search & Research
+
+```bash
+infsh app list --search search
+infsh app run tavily/tavily-search --input '{"query": "latest AI news"}' --json
+infsh app run exa/exa-search --input '{"query": "machine learning papers"}' --json
+```
+
+### Other Categories
+
+```bash
+# 3D generation
+infsh app list --search 3d
+
+# Audio / TTS
+infsh app list --search tts
+
+# Twitter/X automation
+infsh app list --search twitter
+```
+
+## Pitfalls
+
+1. **Never guess app IDs** — always run `infsh app list --search <term>` first. App IDs change and new apps are added frequently.
+2. **Always use `--json`** — raw output is hard to parse. The `--json` flag gives structured output with URLs.
+3. **Check authentication** — if commands fail with auth errors, run `infsh login` or verify `INFSH_API_KEY` is set.
+4. **Long-running apps** — video generation can take 30-120 seconds. The terminal tool timeout should be sufficient, but warn the user it may take a moment.
+5. **Input format** — the `--input` flag takes a JSON string. Make sure to properly escape quotes.

+```bash
+infsh app run user/app-name@1.0.0 --input input.json
+```
+
+## Local File Uploads
+
+The CLI automatically uploads local files when you provide a file path instead of a URL. Any field that accepts a URL also accepts a local path:
+
+```bash
+# Upscale a local image
+infsh app run falai/topaz-image-upscaler --input '{"image": "/path/to/photo.jpg", "upscale_factor": 2}'
+
+# Image-to-video from local file
+infsh app run falai/wan-2-5-i2v --input '{"image": "./my-image.png", "prompt": "make it move"}'
+
+# Avatar with local audio and image
+infsh app run bytedance/omnihuman-1-5 --input '{"audio": "/path/to/speech.mp3", "image": "/path/to/face.jpg"}'
+
+# Post tweet with local media
+infsh app run x/post-create --input '{"text": "Check this out!", "media": "./screenshot.png"}'
+```
+
+Supported paths:
+- Absolute paths: `/home/user/images/photo.jpg`
+- Relative paths: `./image.png`, `../data/video.mp4`
+- Home directory: `~/Pictures/photo.jpg`
+
+## Generate Sample Input
+
+Before running, generate a sample input file:
+
+```bash
+infsh app sample falai/flux-dev-lora
+```
+
+Save to file:
+
+```bash
+infsh app sample falai/flux-dev-lora --save input.json
+```
+
+Then edit `input.json` and run:
+
+```bash
+infsh app run falai/flux-dev-lora --input input.json
+```
+
+## Workflow Example
+
+### Image Generation with FLUX
+
+```bash
+# 1. Get app details
+infsh app get falai/flux-dev-lora
+
+# 2. Generate sample input
+infsh app sample falai/flux-dev-lora --save input.json
+
+# 3. Edit input.json
+# {
+#   "prompt": "a cat astronaut floating in space",
+#   "num_images": 1,
+#   "image_size": "landscape_16_9"
+# }
+
+# 4. Run
+infsh app run falai/flux-dev-lora --input input.json
+```
+
+### Video Generation with Veo
+
+```bash
+# 1. Generate sample
+infsh app sample google/veo-3-1-fast --save input.json
+
+# 2. Edit prompt
+# {
+#   "prompt": "A drone shot flying over a forest at sunset"
+# }
+
+# 3. Run
+infsh app run google/veo-3-1-fast --input input.json
+```
+
+### Text-to-Speech
+
+```bash
+# Quick inline run
+infsh app run falai/kokoro-tts --input '{"text": "Hello, this is a test."}'
+```
+
+## Task Tracking
+
+When you run an app, the CLI shows the task ID:
+
+```
+Running falai/flux-dev-lora
+Task ID: abc123def456
+```
+
+For long-running tasks, you can check status anytime:
+
+```bash
+# Check task status
+infsh task get abc123def456
+
+# Get result as JSON
+infsh task get abc123def456 --json
+
+# Save result to file
+infsh task get abc123def456 --save result.json
+```
+
+### Run Without Waiting
+
+For very long tasks, run in background:
+
+```bash
+# Submit and return immediately
+infsh app run google/veo-3 --input input.json --no-wait
+
+# Check later
+infsh task get <task-id>
+```
+
+## Output
+
+The CLI returns the app output directly. For file outputs (images, videos, audio), you'll receive URLs to download.
+
+Example output:
+
+```json
+{
+  "images": [
+    {
+      "url": "https://cloud.inference.sh/...",
+      "content_type": "image/png"
+    }
+  ]
+}
+```
+
+## Error Handling
+
+| Error | Cause | Solution |
+|-------|-------|----------|
+| "invalid input" | Schema mismatch | Check `infsh app get` for required fields |
+| "app not found" | Wrong app name | Check `infsh app list --search` |
+| "quota exceeded" | Out of credits | Check account balance |

+license: MIT
+tags: [huggingface, hf, models, datasets, hub, mlops]
+---
+
+# Hugging Face CLI (`hf`) Reference Guide
+
+The `hf` command is the modern command-line interface for interacting with the Hugging Face Hub, providing tools to manage repositories, models, datasets, and Spaces.
+
+> **IMPORTANT:** The `hf` command replaces the now deprecated `huggingface-cli` command.
+
+## Quick Start
+*   **Installation:** `curl -LsSf https://hf.co/cli/install.sh | bash -s`
+*   **Help:** Use `hf --help` to view all available functions and real-world examples.
+*   **Authentication:** Recommended via `HF_TOKEN` environment variable or the `--token` flag.
+
+---
+
+## Core Commands
+
+### General Operations
+*   `hf download REPO_ID`: Download files from the Hub.
+*   `hf upload REPO_ID`: Upload files/folders (recommended for single-commit).
+*   `hf upload-large-folder REPO_ID LOCAL_PATH`: Recommended for resumable uploads of large directories.
+*   `hf sync`: Sync files between a local directory and a bucket.
+*   `hf env` / `hf version`: View environment and version details.
+
+### Authentication (`hf auth`)
+*   `login` / `logout`: Manage sessions using tokens from [huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
+*   `list` / `switch`: Manage and toggle between multiple stored access tokens.
+*   `whoami`: Identify the currently logged-in account.
+
+### Repository Management (`hf repos`)
+*   `create` / `delete`: Create or permanently remove repositories.
+*   `duplicate`: Clone a model, dataset, or Space to a new ID.
+*   `move`: Transfer a repository between namespaces.
+*   `branch` / `tag`: Manage Git-like references.
+*   `delete-files`: Remove specific files using patterns.
+
+---
+
+## Specialized Hub Interactions
+
+### Datasets & Models
+*   **Datasets:** `hf datasets list`, `info`, and `parquet` (list parquet URLs).
+*   **SQL Queries:** `hf datasets sql SQL` — Execute raw SQL via DuckDB against dataset parquet URLs.
+*   **Models:** `hf models list` and `info`.
+*   **Papers:** `hf papers list` — View daily papers.
+
+### Discussions & Pull Requests (`hf discussions`)
+*   Manage the lifecycle of Hub contributions: `list`, `create`, `info`, `comment`, `close`, `reopen`, and `rename`.
+*   `diff`: View changes in a PR.
+*   `merge`: Finalize pull requests.
+
+### Infrastructure & Compute
+*   **Endpoints:** Deploy and manage Inference Endpoints (`deploy`, `pause`, `resume`, `scale-to-zero`, `catalog`).
+*   **Jobs:** Run compute tasks on HF infrastructure. Includes `hf jobs uv` for running Python scripts with inline dependencies and `stats` for resource monitoring.
+*   **Spaces:** Manage interactive apps. Includes `dev-mode` and `hot-reload` for Python files without full restarts.
+
+### Storage & Automation
+*   **Buckets:** Full S3-like bucket management (`create`, `cp`, `mv`, `rm`, `sync`).
+*   **Cache:** Manage local storage with `list`, `prune` (remove detached revisions), and `verify` (checksum checks).
+*   **Webhooks:** Automate workflows by managing Hub webhooks (`create`, `watch`, `enable`/`disable`).
+*   **Collections:** Organize Hub items into collections (`add-item`, `update`, `list`).
+
+---
+
+## Advanced Usage & Tips
+
+### Global Flags
+*   `--format json`: Produces machine-readable output for automation.
+*   `-q` / `--quiet`: Limits output to IDs only.
+
+### Extensions & Skills
+*   **Extensions:** Extend CLI functionality via GitHub repositories using `hf extensions install REPO_ID`.
+*   **Skills:** Manage AI assistant skills with `hf skills add`.
