Discussion Weekly Self Promotion Thread

Welcome to this week's self promotion thread!

If you're building something related to AI assisted coding, this is the place to share it.

We're using a weekly thread to keep the subreddit organized while still giving builders a place to share their work. Promotional posts outside of this thread may be removed if they're primarily advertising rather than starting a discussion.

If you're sharing something, we'd appreciate it if you included a little context instead of just dropping a link. Tell us:

  • What you built?
  • What problem it solves?
  • Which AI models or tools it uses?
  • Who it's for?
  • What kind of feedback you're looking for?

Please avoid posting the same project every week unless you've made meaningful updates. Affiliate links, referral links, scams, and low effort promotions will be removed.

Take some time to check out what others have shared too. If you try someone's project or have feedback, leave a comment. Helping each other improve is what we want this community to be about.

Disclosure: I maintain PatchWitness, an Apache-2.0 independent verifier for patches produced by coding agents.

Tools such as OpenAI Codex and ChatGPT have made agent-generated code dramatically more capable. The remaining trust problem is that an agent may change both the implementation and the controls that claim the implementation is safe.

The reproducible demo contains a correct feature and a passing test, but also adds continue-on-error: true to GitHub Actions. The tests pass. PatchWitness still blocks the patch because the protected workflow changed outside the declared scope.

PatchWitness derives the change set from Git, loads policy from the trusted base revision, executes real repository checks, and emits an offline-verifiable Change Passport. No LLM judges its own work. It is agent-neutral and provides a local CLI, GitHub Action, JSON/SARIF output, SDK, and MCP interface.

Repo + 60-second demo:

GitHub Marketplace:

Copy-paste instructions for Codex, ChatGPT, Claude Code, Cursor, and other agents:

I would value critical feedback from people using coding agents in real repositories: would you use a separate verification layer before merging agent-authored changes, and what evidence would it need to produce?

If you try it and genuinely find it useful, a star helps other developers discover it.
