## Quick Start

To start an agent:
```bash
docker compose up -d <service-name>
```

Example:
```bash
docker compose up -d kicad-mcp
```

To view logs:
```bash
docker compose logs -f <service-name>
```

To stop an agent:
```bash
docker compose stop <service-name>
```

## Development Notes

### Critical: STATUS.md Maintenance

**STATUS.md MUST always be kept fully up to date** as it is the single source of truth for operational status of all MCP servers in this project.

When working on any MCP server:
1. **Before starting work**: Review current status in STATUS.md
2. **During work**: Update STATUS.md immediately after each significant milestone (build, start, validation, issues)
3. **After completing work**: Ensure STATUS.md accurately reflects final status with relevant notes
4. **Commit STATUS.md changes**: Always commit STATUS.md updates in separate atomic commits with clear commit messages

### Project Conventions

- All containers use the prefix `kneldevstack-aimiddleware-` for easy identification
- Container names are lowercase for consistency
- Service names are lowercase for Docker Compose compatibility
- Each agent is validated individually before moving to the next
- Vendor directory is gitignored to avoid committing cloned repositories
- **Dockerfile Management**: Custom Dockerfiles created for vendors must be saved in the `dockerfiles/` directory with a corresponding subdirectory structure (e.g., `dockerfiles/bash-language-server/Dockerfile`). These are tracked in git, while vendor/* is not.
- **KiCAD MCP** is host-only - requires KiCAD to be installed on host machine and connects via TCP

### Crush Integration

All LSP and MCP instances must be configured in `crush.json` for Crush to use them. The configuration file uses the following format:

```json
{
  "$schema": "https://charm.land/crush.json",
  "lsp": {
    "bash": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "kneldevstack-aimiddleware-bash-language-server"]
    }
  },
  "mcp": {
    "docker": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "kneldevstack-aimiddleware-docker-mcp"]
    }
  }
}
```

**Configuration Priority:**
1. `.crush.json` (project-local)
2. `crush.json` (project-local)
3. `$HOME/.config/crush/crush.json` (global)

**For Docker-based LSP/MCP instances:**
- Use `docker` as the command
- Include container name as the main argument
- Use `-i` for interactive mode (required for stdio communication)
- Use `--rm` to automatically clean up containers after use

## Validation Checklist

For each agent, verify:
- [ ] Container builds successfully
- [ ] Container starts without errors
- [ ] Logs show proper initialization
- [ ] Environment variables are correctly set (if required)
- [ ] MCP protocol handshake completes
- [ ] Tools are registered and available
- [ ] Resources are accessible (if applicable)
