What problem does it solve? Open pull requests often accumulate review feedback, hidden defects, and unresolved threads that require repeated review-and-fix cycles before they are safe to merge. This Skill automates that hardening loop with independent, model-diverse reviews and traceable repairs while preventing scope creep and unverified merge-ready claims. ## Core Features & Use Cases - Bounded review-repair cycles: Alternate fresh independent code reviews with targeted fixes and validation, capped at three repair rounds plus one verification pass by default. - Model-diverse independent reviewers: Route each review to a different model family than the candidate producer, with context isolation so reviewers never see prior round conclusions. - Scoped authorization modes: Choose Local, Publish, or Respond mode to control whether the Skill edits locally, commits and pushes, or replies to review threads; merges and posted reviews always need separate explicit authorization. - Use Case: A reviewer leaves blocking feedback on your PR. Ask the agent to harden the PR, and it fixes credible findings, runs the repository's tests, re-reviews the exact new candidate with a different model, and reports convergence or a precise blocker. ## Quick Start Use harden-pr to review and fix the open pull request for this branch until it converges or hits the round budget.
