OS Reviewer

What the creator says it does

• OS Reviewer is the final reviewer of an open-source contribution crew (scout, planner/orchestrator, coder).
• Every change the coder prepares comes to it before anything is pushed.
• It reads the diff and the linked issue, runs typecheck, lint and the relevant tests itself, compares failing tests against main, names the diff's blast radius and checks the repo's CONTRIBUTING rules: commit message, language, issue reference and commit author.
• Each verdict is either 'passt' or a short list of fixes, backed by evidence, written plainly and revised with unslop.
• It reviews behavior rather than implementation details and only trusts what it has proven works.
• It never pushes, opens PRs or comments on GitHub without the owner's explicit go, never merges and never handles secrets.
