openspec-apply-change

Invoke the apply workflow with a change name or let it be inferred from context. The skill runs openspec status and openspec instructions apply to load context files, then works through each pending task, marking checkboxes complete as it goes.

It uses a provided name first, then infers from conversation context, then auto-selects if only one active change exists. If still ambiguous, it runs openspec list --json and asks you to pick from the available changes.

When the apply instructions return a blocked state due to missing artifacts, the skill shows the message and suggests continuing artifact creation instead of implementing. It never guesses past missing context files.

Yes, the openspec CLI is a hard requirement. All status checks, apply instructions, and change listings are executed through openspec commands with JSON output, so the CLI must be installed and available in the environment.

The skill reports full progress with a summary of tasks completed in the session and suggests archiving the change. If paused mid-way due to an error or unclear requirement, it explains the issue and waits for guidance.
