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 status 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 available changes via openspec list --json when ambiguous. - Status-Aware Implementation: Parses openspec status and openspec instructions apply output to understand the schema, progress, and remaining tasks before writing code. - Task Loop with Guardrails: Implements each pending task, marks checkboxes complete in the tasks file, and pauses on ambiguity, design issues, or errors instead of guessing. - Use Case: You have an approved OpenSpec change with a tasks file. Invoke this skill to work through all remaining tasks, updating checkboxes as each one is completed, until the change is ready to archive. ## Quick Start Ask the assistant to start implementing the tasks for your current OpenSpec change, optionally naming the change explicitly.
