What problem does it solve? It removes the guesswork of turning an OpenSpec change proposal into working code by walking through the change's task list, reading the right context files, and tracking progress until every task is done or blocked. ## Core Features & Use Cases - Change selection and status inspection: Resolves the target change from user input or conversation context, then reads schema, progress, and task state via openspec status and openspec instructions apply. - Guided task implementation loop: Reads context files (proposal, specs, design, tasks), implements each pending task, and marks checkboxes complete as it goes. - Blocked and completion handling: Detects blocked or all-done states, suggests next actions such as creating missing artifacts or archiving the change. - Use Case: After drafting a spec-driven change for a new auth feature, run the skill to implement all seven tasks in order, pausing automatically when a design issue surfaces. ## Quick Start Ask the assistant to implement the tasks for your OpenSpec change, optionally naming the change, for example by saying to apply the change add-auth.
