What problem does it solve? Changes made outside a spec → plan → implement workflow skip tests, code review, and documentation, leaving the codebase undocumented and unverified. Retrofit closes that gap after the fact by analyzing the actual diff, running reviewers, and proposing the missing artifacts before the change leaves your machine. ## Core Features & Use Cases - Intent-vs-diff reconciliation: Compares your description of a change against the actual git diff (committed, uncommitted, and untracked files) and surfaces discrepancies as findings. - Parallel review orchestration: Dispatches accessibility, code-quality, and performance reviewers against the computed retrofit diff, collecting findings by severity. - Test and documentation gap analysis: Classifies the work type (new-capability, change-to, fix-infra) and drafts the appropriate tests, feature docs, or runbooks. - Confirm-before-write workflow: Presents a two-bucket proposal (auto-applicable vs. human decision) and applies only what you explicitly approve. - Use Case: You made a quick front-end tweak directly and are about to commit. Run retrofit to get a review of the diff, edge cases you missed, and drafted tests and doc updates — then approve only what you want applied. ## Quick Start Ask the AI to run the retrofit skill with a short description of what you changed before committing your work.
