fix: revert accidental summary_target_tokens change + add docs for context_length config

- Revert summary_target_tokens from 2500 back to 500 (accidental change
  during patching)
- Add 'Context Length Detection' section to Custom & Self-Hosted docs
  explaining model.context_length config override

-When subagents overwrite this global, `execute_code` calls after delegation may fail with missing tool imports. Known bug.

+# 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
+
+# Voice
+stt:
+  enabled: true
+  provider: local           # local, groq, openai
+tts:
+  provider: elevenlabs      # elevenlabs, openai, kokoro, fish
+
+# Display
+display:
+  skin: default             # default, ares, mono, slate
+  tool_progress: full       # full, compact, off
+  background_process_notifications: all  # all, result, error, off
+```
+
+Edit with `hermes config edit` or `hermes config set KEY VALUE`.
+
+## Gateway Commands (Messaging Platforms)
+
+| Command | What it does |
+|---------|-------------|
+| /reset or /new | Fresh session (picks up new tool config) |
+| /help | Show all commands |
+| /model [name] | Show or change model |
+| /compact | Compress conversation to save context |
+| /voice [mode] | Configure voice replies |
+| /reasoning [effort] | Set reasoning level |
+| /sethome | Set home channel for cron/notifications |
+| /restart | Restart the gateway (picks up config changes) |
+| /status | Show session info |
+| /retry | Retry last message |
+| /undo | Remove last exchange |
+| /personality [name] | Set agent personality |
+| /skill [name] | Load a skill |
+
+## 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`

+description: Hugging Face Hub CLI (hf) — search, download, and upload models and datasets, manage repos, query datasets with SQL, deploy inference endpoints, manage Spaces and buckets.
+version: 1.0.0
+author: Hugging Face
+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`.
