The problem

AI agents are fast at writing code and painful to ship. Review, QA or the deploy finds what the agent missed. The pull request is too big to review, and nobody can explain the code the agent wrote.

What it does

harnex gives your agent a workflow:

  • A short plan you approve. A few lines in chat, and about 40 lines when the change is risky.
  • Test-first code. The smallest change that works, using your repo’s own test, build and run commands.
  • Independent validation and review. A fresh reviewer that has not seen the code being written.
  • A pre-PR gate. The checks a pull-request review would run, before the PR exists.

More risk means more checks: Quick, Standard or Full, picked from the change.
