Does this skill require any external dependencies?

Yes, this skill requires the openspec CLI to be installed and configured in your environment to manage changes and artifacts.

What happens if a task is unclear or implementation reveals a design issue?

The skill will pause implementation and report the issue, allowing you to clarify requirements or update design artifacts before proceeding.

Does it automatically update my documentation or task files?

Yes, the skill automatically updates task checkboxes (from [ ] to [x]) in your task files immediately after a task implementation is completed.

How does the skill handle multiple active changes?

If the change name is ambiguous, the skill runs 'openspec list' and uses the AskUserQuestion tool to allow you to select the correct change manually.

What is the primary purpose of the OpenSpec Apply Change skill?

It automates the implementation of tasks defined within an OpenSpec change, ensuring that code changes align with pre-defined design specifications and requirements.

Productivity & Workflow

Automates the implementation of development tasks by executing spec-driven changes and tracking progress through completion.

The openspec-apply-change skill streamlines the development lifecycle by translating OpenSpec specifications into actionable code changes. It manages the entire implementation process—from inferring context and reading design documents to executing focused code modifications and updating task statuses. By maintaining a continuous implementation loop and handling blockers gracefully, it ensures that code remains perfectly aligned with the original proposal while providing the user with real-time progress updates and clear state management.
