agent-setup 是做什麼的？
Set up a repository for effective agent-assisted development. Orchestrates opt-in phases — curated skill recommendations based on the detected stack (web, React Native, iOS, Android, Python, …), a context-management playbook and stack-aware quality gates (lint/typecheck/react-doctor/…) written into CLAUDE.md, a permissions allowlist, deterministic hooks (including write-protection for vendored third-party skills), and supply-chain guards (minimum-release-age for bun/pnpm/uv). Use when the user asks to "set up this repo for agents", "agent setup", "what skills should I add", "recommend skills", "set up quality gates / guardrails", or is bootstrapping agent tooling in a new or existing project.
