fix: use per-thread persistent event loops in worker threads

Replace asyncio.run() with thread-local persistent event loops for
worker threads (e.g., delegate_task's ThreadPoolExecutor). asyncio.run()
creates and closes a fresh loop on every call, leaving cached
httpx/AsyncOpenAI clients bound to a dead loop — causing 'Event loop is
closed' errors during GC when parallel subagents clean up connections.

The fix mirrors the main thread's _get_tool_loop() pattern but uses
threading.local() so each worker thread gets its own long-lived loop,
avoiding both cross-thread contention and the create-destroy lifecycle.

Added 4 regression tests covering worker loop persistence, reuse,
per-thread isolation, and separation from the main thread's loop.

 ### `_last_resolved_tool_names` is a process-global in `model_tools.py`
-When subagents overwrite this global, `execute_code` calls after delegation may fail with missing tool imports. Known bug.
+`_run_single_child()` in `delegate_tool.py` saves and restores this global around subagent execution. If you add new code that reads this global, be aware it may be temporarily stale during child agent runs.
+
+### DO NOT hardcode cross-tool references in schema descriptions
+Tool schema descriptions must not mention tools from other toolsets by name (e.g., `browser_navigate` saying "prefer web_search"). Those tools may be unavailable (missing API keys, disabled toolset), causing the model to hallucinate calls to non-existent tools. If a cross-reference is needed, add it dynamically in `get_tool_definitions()` in `model_tools.py` — see the `browser_navigate` / `execute_code` post-processing blocks for the pattern.

+"""Generic webhook platform adapter.

+Runs an aiohttp HTTP server that receives webhook POSTs from external
+services (GitHub, GitLab, JIRA, Stripe, etc.), validates HMAC signatures,
+transforms payloads into agent prompts, and routes responses back to the
+source or to another configured platform.
+
+Configuration lives in config.yaml under platforms.webhook.extra.routes.
+Each route defines:
+  - events: which event types to accept (header-based filtering)
+  - secret: HMAC secret for signature validation (REQUIRED)
+  - prompt: template string formatted with the webhook payload
+  - skills: optional list of skills to load for the agent
+  - deliver: where to send the response (github_comment, telegram, etc.)
+  - deliver_extra: additional delivery config (repo, pr_number, chat_id)
+
+Security:
+  - HMAC secret is required per route (validated at startup)
+  - Rate limiting per route (fixed-window, configurable)
+  - Idempotency cache prevents duplicate agent runs on webhook retries
+  - Body size limits checked before reading payload
+  - Set secret to "INSECURE_NO_AUTH" to skip validation (testing only)

+# FastMCP
+
+Build MCP servers in Python with FastMCP, validate them locally, install them into MCP clients, and deploy them as HTTP endpoints.
+
+## When to Use
+
+Use this skill when the task is to:
+
+- create a new MCP server in Python
+- wrap an API, database, CLI, or file-processing workflow as MCP tools
+- expose resources or prompts in addition to tools
+- smoke-test a server with the FastMCP CLI before wiring it into Hermes or another client
+- install a server into Claude Code, Claude Desktop, Cursor, or a similar MCP client
+- prepare a FastMCP server repo for HTTP deployment
+
+Use `native-mcp` when the server already exists and only needs to be connected to Hermes. Use `mcporter` when the goal is ad-hoc CLI access to an existing MCP server instead of building one.
+
+## Prerequisites
+
+Install FastMCP in the working environment first:
+
+```bash
+pip install fastmcp
+fastmcp version
+```
+
+For the API template, install `httpx` if it is not already present:
+
+```bash
+pip install httpx
+```
+
+## Included Files
+
+### Templates
+
+- `templates/api_wrapper.py` - REST API wrapper with auth header support
+- `templates/database_server.py` - read-only SQLite query server
+- `templates/file_processor.py` - text-file inspection and search server
+
+### Scripts
+
+- `scripts/scaffold_fastmcp.py` - copy a starter template and replace the server name placeholder
+
+### References
+
+- `references/fastmcp-cli.md` - FastMCP CLI workflow, installation targets, and deployment checks
+
+## Workflow
+
+### 1. Pick the Smallest Viable Server Shape
+
+Choose the narrowest useful surface area first:
+
+- API wrapper: start with 1-3 high-value endpoints, not the whole API
+- database server: expose read-only introspection and a constrained query path
+- file processor: expose deterministic operations with explicit path arguments
+- prompts/resources: add only when the client needs reusable prompt templates or discoverable documents
+
+Prefer a thin server with good names, docstrings, and schemas over a large server with vague tools.
+
+### 2. Scaffold from a Template
+
+Copy a template directly or use the scaffold helper:
+
+```bash
+python ~/.hermes/skills/mcp/fastmcp/scripts/scaffold_fastmcp.py \
+  --template api_wrapper \
+  --name "Acme API" \
+  --output ./acme_server.py
+```
+
+Available templates:
+
+```bash
+python ~/.hermes/skills/mcp/fastmcp/scripts/scaffold_fastmcp.py --list
+```
+
+If copying manually, replace `__SERVER_NAME__` with a real server name.
+
+### 3. Implement Tools First
+
+Start with `@mcp.tool` functions before adding resources or prompts.
+
+Rules for tool design:
+
+- Give every tool a concrete verb-based name
+- Write docstrings as user-facing tool descriptions
+- Keep parameters explicit and typed
+- Return structured JSON-safe data where possible
+- Validate unsafe inputs early
+- Prefer read-only behavior by default for first versions
+
+Good tool examples:
+
+- `get_customer`
+- `search_tickets`
+- `describe_table`
+- `summarize_text_file`
+
+Weak tool examples:
+
+- `run`
+- `process`
+- `do_thing`
+
+### 4. Add Resources and Prompts Only When They Help
+
+Add `@mcp.resource` when the client benefits from fetching stable read-only content such as schemas, policy docs, or generated reports.
+
+Add `@mcp.prompt` when the server should provide a reusable prompt template for a known workflow.
+
+Do not turn every document into a prompt. Prefer:
+
+- tools for actions
+- resources for data/document retrieval
+- prompts for reusable LLM instructions
+
+### 5. Test the Server Before Integrating It Anywhere
+
+Use the FastMCP CLI for local validation:
+
+```bash
+fastmcp inspect acme_server.py:mcp
+fastmcp list acme_server.py --json
+fastmcp call acme_server.py search_resources query=router limit=5 --json
+```
+
+For fast iterative debugging, run the server locally:
+
+```bash
+fastmcp run acme_server.py:mcp
+```
+
+To test HTTP transport locally:
+
+```bash
+fastmcp run acme_server.py:mcp --transport http --host 127.0.0.1 --port 8000
+fastmcp list http://127.0.0.1:8000/mcp --json
+fastmcp call http://127.0.0.1:8000/mcp search_resources query=router --json
+```
+
+Always run at least one real `fastmcp call` against each new tool before claiming the server works.
+
+### 6. Install into a Client When Local Validation Passes
+
+FastMCP can register the server with supported MCP clients:
+
+```bash
+fastmcp install claude-code acme_server.py
+fastmcp install claude-desktop acme_server.py
+fastmcp install cursor acme_server.py -e .
+```
+
+Use `fastmcp discover` to inspect named MCP servers already configured on the machine.
+
+When the goal is Hermes integration, either:
+
+- configure the server in `~/.hermes/config.yaml` using the `native-mcp` skill, or
+- keep using FastMCP CLI commands during development until the interface stabilizes
+
+### 7. Deploy After the Local Contract Is Stable
+
+For managed hosting, Prefect Horizon is the path FastMCP documents most directly. Before deployment:
+
+```bash
+fastmcp inspect acme_server.py:mcp
+```
+
+Make sure the repo contains:
+
+- a Python file with the FastMCP server object
+- `requirements.txt` or `pyproject.toml`
+- any environment-variable documentation needed for deployment
+
+For generic HTTP hosting, validate the HTTP transport locally first, then deploy on any Python-compatible platform that can expose the server port.
+
+## Common Patterns
+
+### API Wrapper Pattern
+
+Use when exposing a REST or HTTP API as MCP tools.
+
+Recommended first slice:
+
+- one read path
+- one list/search path
+- optional health check
+
+Implementation notes:
+
+- keep auth in environment variables, not hardcoded
+- centralize request logic in one helper
+- surface API errors with concise context
+- normalize inconsistent upstream payloads before returning them
+
+Start from `templates/api_wrapper.py`.
+
+### Database Pattern
+
+Use when exposing safe query and inspection capabilities.
+
+Recommended first slice:
+
+- `list_tables`
+- `describe_table`
+- one constrained read query tool
+
+Implementation notes:
+
+- default to read-only DB access
+- reject non-`SELECT` SQL in early versions
+- limit row counts
+- return rows plus column names
+
+Start from `templates/database_server.py`.
+
+### File Processor Pattern
+
+Use when the server needs to inspect or transform files on demand.
+
+Recommended first slice:
+
+- summarize file contents
+- search within files
+- extract deterministic metadata
+
+Implementation notes:
+
+- accept explicit file paths
+- check for missing files and encoding failures
+- cap previews and result counts
+- avoid shelling out unless a specific external tool is required
+
+Start from `templates/file_processor.py`.
+
+## Quality Bar
+
+Before handing off a FastMCP server, verify all of the following:
+
+- server imports cleanly
+- `fastmcp inspect <file.py:mcp>` succeeds
+- `fastmcp list <server spec> --json` succeeds
+- every new tool has at least one real `fastmcp call`
+- environment variables are documented
+- the tool surface is small enough to understand without guesswork
+
+## Troubleshooting
+
+### FastMCP command missing
+
+Install the package in the active environment:
+
+```bash
+pip install fastmcp
+fastmcp version
+```
+
+### `fastmcp inspect` fails
+
+Check that:
+
+- the file imports without side effects that crash
+- the FastMCP instance is named correctly in `<file.py:object>`
+- optional dependencies from the template are installed
+
+### Tool works in Python but not through CLI
+
+Run:
+
+```bash
+fastmcp list server.py --json
+fastmcp call server.py your_tool_name --json
+```
+
+This usually exposes naming mismatches, missing required arguments, or non-serializable return values.
+
+### Hermes cannot see the deployed server
+
+The server-building part may be correct while the Hermes config is not. Load the `native-mcp` skill and configure the server in `~/.hermes/config.yaml`, then restart Hermes.

+# FastMCP CLI Reference
+
+Use this file when the task needs exact FastMCP CLI workflows rather than the higher-level guidance in `SKILL.md`.
+
+## Install and Verify
+
+```bash
+pip install fastmcp
+fastmcp version
+```
+
+FastMCP documents `pip install fastmcp` and `fastmcp version` as the baseline installation and verification path.
+
+## Run a Server
+
+Run a server object from a Python file:
+
+```bash
+fastmcp run server.py:mcp
+```
+
+Run the same server over HTTP:
+
+```bash
+fastmcp run server.py:mcp --transport http --host 127.0.0.1 --port 8000
+```
+
+## Inspect a Server
+
+Inspect what FastMCP will expose:
+
+```bash
+fastmcp inspect server.py:mcp
+```
+
+This is also the check FastMCP recommends before deploying to Prefect Horizon.

+## List and Call Tools
+
+List tools from a Python file:
+
+```bash
+fastmcp list server.py --json
+```
+
+List tools from an HTTP endpoint:
+
+```bash
+fastmcp list http://127.0.0.1:8000/mcp --json
+```
+
+Call a tool with key-value arguments:
+
+```bash
+fastmcp call server.py search_resources query=router limit=5 --json
+```
+
+Call a tool with a full JSON input payload:
+
+```bash
+fastmcp call server.py create_item '{"name": "Widget", "tags": ["sale"]}' --json
+```
+
+## Discover Named MCP Servers
+
+Find named servers already configured in local MCP-aware tools:
+
+```bash
+fastmcp discover
+```
+
+FastMCP documents name-based resolution for Claude Desktop, Claude Code, Cursor, Gemini, Goose, and `./mcp.json`.
+
+## Install into MCP Clients
+
+Register a server with common clients:
+
+```bash
+fastmcp install claude-code server.py
+fastmcp install claude-desktop server.py
+fastmcp install cursor server.py -e .
+```
+
+FastMCP notes that client installs run in isolated environments, so declare dependencies explicitly when needed with flags such as `--with`, `--env-file`, or editable installs.
+
+## Deployment Checks
+
+### Prefect Horizon
+
+Before pushing to Horizon:
+
+```bash
+fastmcp inspect server.py:mcp
+```
+
+FastMCP’s Horizon docs expect:
+
+- a GitHub repo
+- a Python file containing the FastMCP server object
+- dependencies declared in `requirements.txt` or `pyproject.toml`
+- an entrypoint like `main.py:mcp`
+
+### Generic HTTP Hosting
+
+Before shipping to any other host:
+
+1. Start the server locally with HTTP transport.
+2. Verify `fastmcp list` against the local `/mcp` URL.
+3. Verify at least one `fastmcp call`.
+4. Document required environment variables.

+# 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/`
+
+## 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

+
+## 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
+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`.
