# FEATURES KNOWLEDGE BASE

## OVERVIEW

Claude Code compatibility layer + core feature modules. Commands, skills, agents, MCPs, hooks from Claude Code work seamlessly.

## LOADER PRIORITY

| Loader | Priority (highest first) |
|--------|--------------------------|
| Commands | `.opencode/command/` > `~/.config/opencode/command/` > `.claude/commands/` > `~/.claude/commands/` |
| Skills | `.opencode/skill/` > `~/.config/opencode/skill/` > `.claude/skills/` > `~/.claude/skills/` |
| Agents | `.claude/agents/` > `~/.claude/agents/` |
| MCPs | `.claude/.mcp.json` > `.mcp.json` > `~/.claude/.mcp.json` |

## CONFIG TOGGLES

```json
{
  "claude_code": {
    "mcp": false,      // Skip .mcp.json
    "commands": false, // Skip commands/*.md
    "skills": false,   // Skip skills/*/SKILL.md
    "agents": false,   // Skip agents/*.md
    "hooks": false     // Skip settings.json hooks
  }
}
```

## BACKGROUND AGENT

- Lifecycle: pending → running → completed/failed
- OS notification on complete
- `background_output` to retrieve results
- `background_cancel` with task_id or all=true

## SKILL MCP

- MCP servers embedded in skill YAML frontmatter
- Lazy client loading, session-scoped cleanup
- `skill_mcp` tool exposes capabilities

## ANTI-PATTERNS

- Blocking on load (loaders run at startup)
- No error handling (always try/catch)
- Ignoring priority order
- Writing to ~/.claude/ (read-only)
