What problem does it solve? When a code review catches a mistake, that lesson is usually lost after the PR merges. This Skill turns a one-off review comment into a standing, committed Handbook rule so the same mistake is flagged on every future PR. ## Core Features & Use Cases - Guided rule capture: Walks the operator from a raw review finding through bucket selection (domain, architecture, general, language), slug derivation, and a five-section rule template. - Mandatory approval gate: Previews the complete file and writes nothing until the operator explicitly confirms, keeping the Handbook operator-curated rather than auto-generated. - Advisory-by-default enforcement: Writes rules as advisory, with an opt-in --blocking flag reserved for security or data-loss concerns. - Use Case: A reviewer catches a missing Stripe webhook signature check. Run the skill with the review comment, pick the domain bucket, and it writes omnigrid/handbooks/domain/stripe-webhooks/verify-webhook-signatures.md ready to commit. ## Quick Start Run /codify-rule followed by a one-sentence description of the review finding you want to turn into a standing Handbook rule.
