Use when implementing complex TypeScript type logic: generics, conditional or mapped types, template literal types, reusable type utilities. Triggers - TypeScript 타입, 제네릭, 타입 유틸리티.
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
Build reproducible product-demo videos for arbitrary web applications by inspecting the real UI, planning a service-specific storyboard, generating Playwright recording code, and assembling silent captioned 60fps MP4s with FFmpeg. Use when Codex is asked to create, revise, automate, or package a web-service introduction, demo-day video, feature walkthrough, or UI product film from a live or local web app.
Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
