What problem does it solve? Engineers and AI agents often deliver code that technically passes but misses the spirit of a requirement, silently descopes hard items, or introduces unnecessary abstractions. This Skill provides shared implementation guidance that keeps changes minimal, correct end-to-end, and consistent with existing conventions. ## Core Features & Use Cases - Excellence Bar: Enforces outcome quality on in-scope work, requiring end-to-end working behavior rather than code that merely compiles or passes self-written tests. - Anti-Punt Rules: Defines exactly three options for hard requirements — complete them, halt with a blocker report, or get explicit sign-off — preventing silent descoping. - Minimal-Change Discipline: Directs agents to understand existing code first, reuse utilities and patterns, and avoid opportunistic rewrites or unneeded abstractions. - Use Case: An execution agent implementing a feature spec uses this Skill to stay within the declared scope, surface blockers honestly, and deliver work a senior engineer would approve. ## Quick Start Apply the implementation-principles skill while implementing this feature spec to keep the change minimal, correct, and within scope.
