Use when the user asks for a standup, daily summary, usage tips, workflow recommendations, wants to search or find past sessions by keyword/file/PR, wants to reindex their session store, or asks about deleting session data.
Create a hook (.json) to enforce policy or automate agent lifecycle events.

Use when working on the Chat Customizations editor — the management UI for agents, skills, instructions, hooks, prompts, MCP servers, and plugins.
Generate or update chat customization files for AI coding agents
Audit code for memory leaks and disposable issues. Use when reviewing event listeners, DOM handlers, lifecycle callbacks, or fixing leak reports. Covers addDisposableListener, Event.once, MutableDisposable, DisposableStore, and onWillDispose patterns.

If no clear rule emerges from the conversation, clarify:
Explore the codebase using subagents if you need more context.
Remember to follow the agent-customization guidelines to create highly effective instructions.
