Three things we built for our own agents.

Two are free. None needs an account with us.

Andon free

Catches a false "done" before it reaches you. Two lines install the claim-check Stop hook in warn mode and a memory hook that orients your agent each session. Open source under MIT. 168 stars on GitHub. The maintainer of Serial-Studio adapted it.

30-second proof, no install. From inside a clone, run the three lines under "Reproduce it in 30 seconds" in the README. The hook answers with a message asking for claim-specific verification.

AI Agent Operator Kit free

Runs the same workflow every session, with 5 skills that chain. Capture your open loops and cut the list to the part that matters. Audit yourself for drift and reality-check a build before you start. Then write the outside copy. 6 more skills sit in the same repo, each one a single SKILL.md file. Open source under MIT.

shgit clone https://github.com/PrimeFoldTools/primefold-skills-public.git

30-second proof. Type "Reality check this" and paste one idea you were about to spend a day on. You get an evidence score and a GO or HOLD.

Verification Kit $27 · 30-day refund, no questions

3 Stop hooks that catch what free Andon lets through.

  • Flags a command the agent said it ran but never ran.
  • Flags a number in the final answer with no source in the session.
  • Blocks a "the whole job is done" claim with no proof in the last 15 minutes.
  • Free Andon warns on that claim. The kit's check blocks it.
  • Ships in warn mode. You turn on block.

30-second proof, no install. The kit ships six small transcripts and a script that runs the three hooks on them. Checkout is on Polar. The download is the zip with that hash.

Try it for 30 days. If it is not worth $27 to you, email us and we refund it. No questions.

Also built, not on the shelf.

11 of our skills are public in the Operator Kit above. 35 more sit inside 8 private plugins, for markets, writing, visuals, family life, relationships, property, fact-checking and travel. The prompt library we use every day is not public yet.

If you want one of the private ones, email us what you would use it for.

A script supplies every figure on this page, as read on Nov 3, 2026.
