What problem does it solve? Turning a written plan or root-cause investigation into actual code often drifts: invented symbols, out-of-scope edits, style mismatches, and untracked decisions. This Skill executes a validated contract end-to-end while enforcing scope discipline, reuse of existing code, and auditable decision records. ## Core Features & Use Cases - Contract-driven implementation: Executes a WBS plan or Investigation Report exactly as written, halting on logic gaps, contract conflicts, or unauthorized dependencies instead of guessing. - Reuse-first discipline: Runs a mandatory reuse sweep against the repo's shared utilities and ARCHITECTURE.md Reuse Map before writing any new helper, preventing duplicate code. - Auditable execution records: Tracks material decisions in DECISIONS.md and produces a structured Code Execution Report covering progress, files modified, tests, and acceptance criteria. - Use Case: Hand the Skill a WBS plan for a new feature; it reads the affected files, implements each task in dependency order, runs the project's lint and test scripts, and saves a handoff report with any gaps surfaced. ## Quick Start Use the code skill to implement the WBS plan in the handoff folder for the user-settings feature and report the results.
