openspec-apply-change

What problem does it solve? It removes the manual effort of tracking and executing implementation tasks defined in an OpenSpec change, keeping task checkboxes, progress, and context files synchronized during development. ## Core Features & Use Cases - Change Selection: Automatically infers the active change from conversation context or lists available changes via openspec list --json when ambiguous. - Task Implementation Loop: Reads context files (proposal, specs, design, tasks), implements each pending task, and marks checkboxes complete as work progresses. - State Handling: Detects blocked or completed states, suggests archiving finished changes, and pauses with structured options when issues arise. - Use Case: A developer with a spec-driven change containing 7 tasks asks the assistant to start implementation; the skill reads the tasks file, implements each item, updates checkboxes, and reports progress until all tasks are done. ## Quick Start Ask the assistant to start implementing the tasks for your current OpenSpec change, optionally naming the change explicitly.
