What problem does it solve? Turning an approved change proposal into working code often loses track of which tasks are done, which remain, and whether the specs still match the implementation. This Skill drives the implementation loop task by task, keeping the task checklist and specs in step as work progresses. ## Core Features & Use Cases - Change selection and status inspection: Resolves the target change from a name, conversation context, or an interactive picker backed by openspec list --json, then reads schema and progress via openspec status and openspec instructions apply. - Task-by-task implementation loop: Reads the context files the CLI lists (specs, tasks, design, proposal), implements each pending task with minimal scoped edits, and flips - [ ] to - [x] immediately after completion. - Structured pause and completion reporting: Emits progress summaries ("N/M tasks complete"), pauses with options on ambiguity, design issues, or blockers, and suggests archiving when all tasks finish. - Use Case: After approving an OpenSpec proposal for a new API endpoint, run the apply step to have the agent implement each planned task in order, updating the tasks file as it goes and pausing for guidance if a design flaw surfaces. ## Quick Start Ask the agent to apply the OpenSpec change named add-user-auth and implement its remaining tasks one by one.
