What problem does it solve? It turns an OpenSpec change's task list into actual code changes by driving the openspec CLI through selection, status checks, context loading, and task-by-task implementation with progress tracking. ## Core Features & Use Cases - Change Selection: Infers the target change from conversation context, auto-selects when only one active change exists, or lists available changes for the user to pick. - Schema-Aware Execution: Reads status and apply instructions from the openspec CLI to discover the workflow schema, context files, progress, and blocked or completed states. - Task Implementation Loop: Works through pending tasks one by one, marking each checkbox complete in the tasks file, and pauses on ambiguity, design issues, or errors. - Use Case: A developer has a spec-driven change with 7 tasks defined in OpenSpec and asks the assistant to implement them; the skill reads the proposal, specs, design, and tasks, then implements each task while reporting progress. ## Quick Start Ask the assistant to start implementing the tasks for a named OpenSpec change, optionally specifying a registered store.
