I made a tiny CLI to sanity-check AI-written PR diffs

I keep seeing AI-written PRs that look fine at first glance, but the risky parts are buried in the diff.

So I made Agent Diff Sentinel, a small open-source CLI that scans a git diff and points reviewers to the stuff worth checking first:

auth, billing, security, database, CI, and dependency changes
secret-looking added lines
missing tests
oversized generated-looking files
TODO/FIXME/hack markers

It can output plain text, JSON, or Markdown, and it can fail CI on high-risk findings.

I’d love feedback from people using Codex, Cursor, Claude Code, or similar tools on real repos: what diff checks would you want before trusting an AI-assisted PR?

I built Agent Ready Kit, a small open-source CLI for one question that keeps showing up in AI-assisted development:

Can an AI coding agent actually understand and change this repo without wasting the first 20 minutes guessing?

The tool audits a repository locally and gives it an agent-readiness score. It checks the boring-but-important things that make agents useful instead of chaotic:

clear README and install/run instructions
test command discovery
CI/workflow setup
license and contribution basics
env examples
issue templates
docs/examples
AGENTS.md or other agent instructions

It can also generate a starter AGENTS.md so the next coding session has a better map of the project.

Why I made it

A lot of repos are technically open source but not very agent-friendly. Humans can infer missing setup steps from experience; agents usually burn tokens, make guesses, or ask for context that could have been written down once.

I wanted a quick pre-flight check before handing a repo to Codex, Claude Code, Cursor, Copilot, Gemini CLI, or any other coding agent.

What I want feedback on

If you use AI coding agents in real repos, I would love feedback on what the score should include next.

The next checks I am considering:

package manager lockfile consistency
flaky or missing test detection
stale docs vs current scripts
repo-specific agent safety rules
PR-review readiness

If this saves you a setup pass, or if the scoring misses something important, tell me. That feedback is more useful than a vague launch post.
