What problem does it solve? It removes the guesswork of turning an OpenSpec change plan into working code by walking through each task in the change, tracking progress, and pausing safely when requirements are unclear or blocked. ## Core Features & Use Cases - Change Selection: Automatically infers the active change from context, lists available changes when ambiguous, and supports registered OpenSpec stores via --store flags. - Guided Task Implementation: Reads apply instructions and context files (proposal, specs, design, tasks) from the openspec CLI, then implements each pending task and marks it complete in the tasks file. - State Handling and Guardrails: Detects blocked and all-done states, surfaces scope creep instead of silently narrowing behavior, and reports progress after every session. - Use Case: After drafting a spec-driven change for a new authentication feature, run this Skill to implement all seven planned tasks one by one, with checkboxes updated in the tasks file and a completion summary at the end. ## Quick Start Ask the assistant to implement the tasks for your OpenSpec change, for example by saying "apply the add-auth change".
