# Repo Agent Kit > Free, privacy-first browser tools for creating, checking, and adapting repository instruction files for Codex, Claude Code, Cursor, and GitHub Copilot. Repo Agent Kit is useful when a developer or coding agent needs a copy-ready `AGENTS.md`, a stack-specific starting point, or a private quality check. Generation and audits happen in the browser; repository contents are not uploaded. Use the Markdown resources below for concise, agent-readable product context, or `/llms-full.txt` for a single expanded context file. ## Core tools - [Generator](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/generator.md): Create AGENTS.md, CLAUDE.md, Cursor rules, or GitHub Copilot instructions from project details. - [Private checker](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/checker.md): Score an instruction file across eight operational categories and produce repair blocks. - [Template library](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/templates.md): Copy-ready AGENTS.md templates for eight development stacks. - [Examples lab](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/examples.md): Before-and-after examples for small projects, production web applications, and monorepos. - [GitHub repository audit](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/github-audit.md): Create a shareable coding-agent readiness report for any public GitHub repository. - [GitHub to AGENTS.md](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/github-to-agents.md): Generate a deterministic, evidence-backed AGENTS.md from a public GitHub repository without an AI key. - [Manifest to AGENTS.md](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/manifest-to-agents.md): Generate a local, copy-ready AGENTS.md from package.json, pyproject.toml, go.mod, or Cargo.toml. - [Agent Readiness Benchmark](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/benchmark.md): Explore a reproducible, commit-pinned readiness dataset for 10 public development repositories. ## Reference - [Privacy and metrics](https://repo-agent-kit.sunxiayi.chatgpt.site/docs/metrics.md): What the public growth dashboard measures and deliberately does not store. - [Full agent context](https://repo-agent-kit.sunxiayi.chatgpt.site/llms-full.txt): Expanded product, usage, route, and privacy context in one file.
