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`
 `_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.

+  - Rate limiting per route (fixed-window, configurable)
+  - Idempotency cache prevents duplicate agent runs on webhook retries

+
+# 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.
+
+## References
+
+For CLI details, install targets, and deployment checks, read `references/fastmcp-cli.md`.

+# 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.

+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`.

+Hermes persists the endpoint in `config.yaml` and prompts for the context window size so compression triggers at the right time. If you leave context length blank, Hermes auto-detects it from the server's `/models` endpoint or [models.dev](https://models.dev).
 
 This works with Ollama, vLLM, llama.cpp server, SGLang, LocalAI, and others. See the [Configuration guide](../user-guide/configuration.md) for details.
 
+:::tip Ollama users
+If you set a custom `num_ctx` in Ollama (e.g., `ollama run --num_ctx 16384`), make sure to set the matching context length in Hermes — Ollama's `/api/show` reports the model's *maximum* context, not the effective `num_ctx` you configured.

 ### How much does it cost?
 
 Hermes Agent itself is **free and open-source** (MIT license). You pay only for the LLM API usage from your chosen provider. Local models are completely free to run.

+If this happens on the first long conversation, Hermes may have the wrong context length for your model. Check what it detected:
+
+```bash
+# Look at the status bar — it shows the detected context length
+/context
+```
+
+To fix context detection, set it explicitly:
+
+```yaml
+# In ~/.hermes/config.yaml
+model:
+  default: your-model-name
+  context_length: 131072  # your model's actual context window
+```
+
+Or for custom endpoints, add it per-model:
+
+```yaml
+custom_providers:
+  - name: "My Server"
+    base_url: "http://localhost:11434/v1"
+    models:
