openspec-apply-change

To start implementing an OpenSpec change, the skill infers the target change from your context, calls the openspec CLI for schema-aware instructions, and iterates through the returned task list to track progress. It auto-selects the change when unambiguous or prompts you to choose.

OpenSpec schema-driven workflow handles context files by fetching dynamic apply instructions via the CLI in JSON mode and reading the specific contextFiles returned. This ensures task execution remains aligned with the change's required schema and minimal scoped changes.

Yes, you need the openspec CLI installed to apply changes and execute tasks. The skill requires calling openspec status and openspec instructions apply in JSON mode to retrieve the task list and context files needed for the implementation workflow.

When a task is blocked or ambiguous during OpenSpec implementation, the workflow pauses execution. Instead of forcing a potentially incorrect change, it halts the iteration loop to prevent unsafe modifications until the ambiguity is resolved.

Yes, you can resume partial progress on an active OpenSpec change. The skill applies when you need to start, continue, or complete work, looping through pending tasks, marking completed ones, and safely pausing on blocked items.

To select the correct OpenSpec change, the skill first attempts to infer it from your conversation context. If multiple active changes exist and the target is ambiguous, it lists available changes and prompts you to select the intended one.
