What happens if a task is unclear or ambiguous?

The skill includes safety guardrails. If a task is vague, the agent will pause implementation and ask the user for clarification rather than guessing.

Can I use this for partially completed projects?

Absolutely. The skill checks the current status of an OpenSpec change and will pick up exactly where you left off based on the remaining tasks.

Does this skill require any additional software?

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

What is the openspec-apply-change skill used for?

It is used to implement tasks from an OpenSpec change plan. It reads your project specifications and systematically applies the required code changes task-by-task.

How does it handle different project structures?

It uses the 'contextFiles' provided by the OpenSpec CLI output, allowing it to adapt to different schemas like spec-driven or custom implementation patterns.

Productivity & Workflow

Automates the execution of development tasks by systematically implementing changes defined within the OpenSpec framework.

The openspec-apply-change skill streamlines the transition from design to code by automating the implementation phase of the OpenSpec workflow. It intelligently reads context files—such as proposals, technical specifications, and design documents—to execute code changes task-by-task while maintaining strict alignment with the original plan. By providing real-time progress tracking and built-in guardrails for ambiguous requirements, this skill ensures that developers can reliably transform abstract specifications into production-ready code with minimal manual overhead.
