## Key Concepts

### Subagents
Specialized AI assistants that run in isolated contexts with custom system prompts and tool access. Built-in types include Explore (read-only, fast), Plan (research for planning), and General-purpose (full capabilities).

### Plugins
Packaged extensions containing skills, agents, hooks, and MCP servers that can be distributed via marketplaces.

### Skills
Reusable prompts and workflows defined in SKILL.md files. Can be invoked with `/skill-name` or automatically by Claude when relevant.

### Hooks
User-defined shell commands that execute at various points in Claude Code's lifecycle (PreToolUse, PostToolUse, Notification, etc.).

### Memory (CLAUDE.md)
Hierarchical instruction files that persist across sessions. Includes project-level, user-level, and managed/enterprise levels.

## Grid Integration Planning

Each section includes a "Grid Integration Opportunities" placeholder at the end for noting potential enhancement areas. Consider:

1. **Subagents** - Grid's multi-agent architecture could leverage custom subagent patterns
2. **Skills** - Grid commands could be exposed as skills for more flexible invocation
3. **Hooks** - Grid could use hooks for state management, logging, and automation
4. **Headless Mode** - Grid daemon mode could leverage the Agent SDK
5. **Memory** - Grid state could integrate with CLAUDE.md for persistence
