openspec-sync-specs

To merge delta specifications safely, the tool reads changes from openspec/changes/<name>/specs and applies added, modified, removed, and renamed requirements to main specs under openspec/specs, preserving unrelated content and ensuring updates do not lose existing work.

When delta specs add or modify requirements, the merge operation updates existing main specs under openspec/specs with the new values. If the target main spec does not exist yet, the tool automatically creates it to capture the updated requirements.

Yes, the spec merge operation is idempotent. You can execute it multiple times with consistent results, and it will preserve unrelated content while safely applying the delta changes to the main specifications.

If deeper clarification is needed during the merge, the tool prompts you for the change name. It gracefully handles missing target specs by creating them and manages conflicts by intelligently merging renamed, modified, or removed requirements without disrupting existing work.

No external dependencies are required to sync openspec delta specifications. The tool operates directly on your openspec directory structure, reading from the changes folder and writing updates to the main specs folder without needing additional packages.
