# 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://repoagentkit.com/docs/generator.md): Create AGENTS.md, CLAUDE.md, Cursor rules, or GitHub Copilot instructions from project details. - [Private checker](https://repoagentkit.com/docs/checker.md): Score an instruction file across eight operational categories and produce repair blocks. - [Configuration smell checker](https://repoagentkit.com/docs/instruction-smell-checker.md): Enter a public GitHub repository or load AGENTS.md or CLAUDE.md locally to screen six research-defined configuration smells with disclosed deterministic early-warning heuristics. - [Configuration smell dataset](https://repoagentkit.com/docs/instruction-smell-report.md): Explore a commit-pinned screen of 39 popular repositories with exact source links plus JSON and CSV downloads. - [Agent Skill and instruction security scanner](https://repoagentkit.com/docs/instruction-security-scanner.md): Recursively scan every SKILL.md and supported instruction file in a public GitHub repository for hidden Unicode, unsafe execution, secret handling, destructive commands, and safety bypasses without executing repository code; run or download the versioned zero-dependency CLI locally, or install its GitHub Action and pre-commit hook. - [Template library](https://repoagentkit.com/docs/templates.md): Copy-ready AGENTS.md templates for eight development stacks. - [Examples lab](https://repoagentkit.com/docs/examples.md): Before-and-after examples for small projects, production web applications, and monorepos. - [GitHub repository audit](https://repoagentkit.com/docs/github-audit.md): Create a shareable coding-agent readiness report for any public GitHub repository. - [GitHub to AGENTS.md](https://repoagentkit.com/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://repoagentkit.com/docs/manifest-to-agents.md): Generate a local, copy-ready AGENTS.md from package.json, pyproject.toml, go.mod, or Cargo.toml. - [Instruction file converter](https://repoagentkit.com/docs/instruction-file-converter.md): Convert one repository instruction file into AGENTS.md, CLAUDE.md, a Cursor .mdc rule, or GitHub Copilot instructions locally. - [Instruction file compatibility planner](https://repoagentkit.com/docs/ai-agent-instruction-files.md): Choose Codex, Claude Code, Cursor, Copilot, Gemini CLI, or Devin Desktop (formerly Windsurf) and get a minimal AGENTS.md-centered file plan. - [Agent Readiness Benchmark](https://repoagentkit.com/docs/benchmark.md): Explore a reproducible, commit-pinned readiness dataset for 10 public development repositories. - [Top 100 AGENTS.md adoption dataset](https://repoagentkit.com/docs/agents-md-adoption.md): Inspect root AGENTS.md adoption across GitHub's 100 most-starred public repositories, pinned to exact commits with JSON and CSV downloads. - [GitHub CLI extension](https://github.com/sunxiayi/gh-agents-md): Install with `gh extension install sunxiayi/gh-agents-md`, create a bundled template with `gh agents-md init`, or print repository-prefilled audit and generator links. ## Reference - [AGENTS.md security review field note](https://repoagentkit.com/field-notes/review-agents-md-security-before-running-coding-agents): A pre-trust checklist for repository instructions plus a copyable, read-only pull-request scan. - [Field Notes RSS](https://repoagentkit.com/field-notes/feed.xml): Evidence-backed implementation notes for coding-agent repository workflows. - [Privacy and metrics](https://repoagentkit.com/docs/metrics.md): What the public growth dashboard measures and deliberately does not store. - [Full agent context](https://repoagentkit.com/llms-full.txt): Expanded product, usage, route, and privacy context in one file.
