What problem does it solve? Turning a planned task list into actual code often loses traceability: nobody records which legacy rules were touched, which behaviors must keep holding true, or what failed mid-run. This Skill executes the actions.md plan phase by phase while producing a complete audit trail for future re-extraction cycles. ## Core Features & Use Cases - Phased task execution: Runs unchecked actions from actions.md in order (Preparação, Testes, Núcleo, Integração, Polimento), respecting dependencies and parallel markers, checking off [X] boxes and appending to progress.jsonl. - Legacy impact report: Generates legacy-impact.md mapping every touched file to architecture.md components with impact type and severity, listing preserved and modified domain rules. - Regression watch list: Creates regression-watch.md with stable watch IDs for modified or removed rules, so future re-extractions can verify nothing silently broke. - Dual context anchoring: Works anchored on legacy extraction artifacts (architecture.md + domain.md) or greenfield artifacts (prd.md + SDD specs), aborting cleanly when neither exists. - Use Case: After running /reversa-to-do to produce an actions.md plan for a new feature, invoke this Skill to implement the tasks, then hand off to /reversa-sync for convergence. ## Quick Start Ask the agent to run reversa-coding to execute the pending actions in the current feature directory and generate the impact and regression reports.
