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: Infers the target change from conversation context or lists available changes via openspec list --json when ambiguous. - Context-Aware Implementation: Reads the schema-specific context files (proposal, specs, design, tasks) returned by openspec instructions apply before writing any code, and explores code structure with CodeGraph. - Progress Tracking & Pause Handling: Marks tasks complete as it goes, shows N/M progress, and pauses with clear options when it hits ambiguity, design issues, or errors. - Use Case: You have an approved OpenSpec change with 7 tasks. Invoke this skill to implement each task sequentially, updating the tasks file checkboxes, until the change is ready to archive. ## Quick Start Ask the agent to start implementing the tasks for your OpenSpec change, optionally naming the change you want to work on.
