openspec-apply-change

Invoke the skill with a change name, or let it infer one from context. It runs openspec status and instructions apply to load context files, then implements each pending task and marks it complete in the tasks file.

Run the apply workflow, which reads the proposal, specs, design, and tasks artifacts listed in contextFiles. The agent works through pending tasks sequentially, keeping code changes minimal and checking off each task as it finishes.

Yes, the skill requires the openspec CLI to be installed, since every step (status, instructions, list, validate) is executed through openspec commands. Without it, the workflow cannot read change state or artifacts.

When status returns a blocked state, the skill shows the message and suggests creating the missing artifact, either via the continue-change skill or by running openspec instructions for the next artifact. It does not bypass the blocked state.

Yes. Run openspec store list --json to find store ids, then pass --store <id> on commands that read or write specs and changes. The flag stays sticky for the rest of the workflow once selected.
