What problem does it solve? Medium-sized changes that span several layers (API, storage, tests) often get either over-engineered with heavy design docs or under-planned with no coordination. This Skill provides a scoped fast path: clarify only real ambiguities, present a compact in-chat plan, and implement immediately without ceremony. ## Core Features & Use Cases - Bounded Clarification: Ask at most 3 batched questions, each with a recommended answer, and only about decisions that change the implementation. - Compact In-Chat Plan: Present a sub-10-line plan covering changes, tests, and assumptions, then proceed straight to coding without waiting for approval gates. - Disciplined Implementation: Enforce KISS principles, reuse existing project utilities, forbid silent scope cuts, TODO stubs, and speculative generality. - Use Case: When adding an endpoint that touches the router, storage layer, and tests, use this Skill to confirm boundary behaviors, show a short plan, and ship the full change with passing tests in one pass. ## Quick Start Use the dev-feature skill to add a new endpoint that spans the API, storage, and test layers of this project.
