A test suite that grew alongside its code tends to pin the shape the code happened to take, not the outcome anyone wanted. Editing either one in place keeps that shape. Commit R removes both halves of one compartment and writes them again in the order that exposes the difference: first the tests, from a hypothesis about what the compartment is for, then the production code those tests now demand. The deletions are commits of their own while the pass runs, so each step can be read against the one before it. Before anything is pushed, a compartment's commits become one that passes the gate…
Commit R is a community-contributed Claude Code skill in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/commit-r/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the operator says "commit R", "commit-R protocol", "remove and rewrite the tests", or asks for a TDD pass that looks for a faster, simpler path to the same outcome.
The Commit R Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 201,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
