Can I use this for existing projects?

Yes, as long as the project is using OpenSpec to manage changes, this skill can be invoked at any time to start or continue implementing tasks.

How does the skill handle implementation errors?

If the skill encounters a blocker, an error, or an ambiguous task, it will pause implementation, report the issue, and wait for your guidance or suggest an artifact update.

Do I need any extra software to use this skill?

Yes, this skill requires the openspec CLI to be installed in your environment to manage changes and retrieve implementation instructions.

What does the openspec-apply-change skill do?

It automates the process of working through a list of tasks defined within an OpenSpec change, ensuring code is written according to pre-defined specifications.

Productivity & Workflow

Automates the systematic implementation of development tasks defined in OpenSpec changes by managing context and tracking progress.

This skill streamlines the software development lifecycle by guiding Claude through the execution phase of an OpenSpec change. It automatically identifies the necessary context files—such as proposals, specifications, and design documents—and works through task lists iteratively. By integrating directly with the OpenSpec CLI, the skill maintains a real-time feedback loop, updating task statuses as code is written, and intelligently pausing for user guidance if it encounters design blockers or ambiguous requirements. This ensures that every code change is minimal, focused, and perfectly aligned with the project's architectural specifications.
