What problem does it solve? Turning an agreed plan or issue into a verified code change often drifts: scope creeps, unrelated changes get tangled in, tests and documentation are skipped, and completion is claimed without evidence. This Skill implements one bounded work unit end to end while preserving unrelated work and recording proof. ## Core Features & Use Cases - Scoped Implementation: Makes the smallest coherent change satisfying all acceptance criteria, including tests, documentation, configuration, and migrations in the same unit. - Domain References: Loads focused guidance for security remediation, browser test repair, and architecture documentation only when the work requires it. - Review-Fix Loop: Verifies each review finding against the current candidate, fixes supported in-scope defects, and explains out-of-scope or unsubstantiated findings. - Use Case: Given a Linear issue describing a bug fix with acceptance criteria, implement the change, add regression tests, rerun the named measurement method, and record before/after evidence without committing until delivery is requested. ## Quick Start Use execute-work to implement the change described in this issue, including tests and verification evidence.
