Use when bootstrapping a new repo for AI-assisted development, when no AGENTS.md / CLAUDE.md / copilot-instructions.md / .cursorrules exists yet, or when consolidating scattered tool-specific config into one source of truth. Triggers on "create AGENTS.md", "set up agent instructions", "new project setup", "configure Claude/Cursor/Copilot/Codex", "onboarding a repo", or noticing duplicated agent config across tool-specific files.
