What problem does it solve? It removes the guesswork of turning an OpenSpec change proposal into working code by reading the change's tasks, context files, and progress state directly from the openspec CLI and guiding implementation task by task. ## Core Features & Use Cases - Change Selection: Infers the target change from conversation context or lists active changes via openspec list --json when ambiguous. - Status-Aware Implementation: Parses openspec status and openspec instructions apply JSON output to determine schema, context files, progress, and blocked or completed states. - Task Loop with Guardrails: Implements each pending task, marks checkboxes complete in the tasks file, and pauses on unclear requirements, design issues, or errors. - Use Case: After drafting an OpenSpec change with proposal, design, and tasks, invoke this skill to work through all 7 tasks sequentially, updating the tasks file as each one completes. ## Quick Start Ask the assistant to implement the tasks from your OpenSpec change, optionally naming the change to apply.
