What problem does it solve? It turns an OpenSpec change's task list into actual code changes, removing the manual work of tracking which tasks are done, reading the right context files, and keeping the tasks file updated during implementation. ## Core Features & Use Cases - Change Selection: Resolves the target change from a provided name, conversation context, or an interactive picker backed by openspec list --json. - Schema-Aware Context Loading: Runs openspec status and openspec instructions apply to discover the workflow schema and read the exact context files (proposal, specs, design, tasks) before writing any code. - Task-by-Task Implementation Loop: Works through pending tasks, marks each one complete in the tasks file, and pauses with structured status output when blocked, ambiguous, or finished. - Use Case: You have an approved OpenSpec change with 7 tasks. Invoke this skill to have the agent read the proposal and specs, implement each task in order, check off the tasks file, and report progress until the change is ready to archive. ## Quick Start Ask the agent to start implementing the tasks for your current OpenSpec change, optionally naming the change to apply.
