What is a delta spec in OpenSpec?

A delta spec is a markdown file representing incremental changes—additions, modifications, or deletions—to be applied to a main specification.

Does this skill overwrite my entire specification file?

No, it uses intelligent merging to apply only the specific changes defined in the delta, preserving existing scenarios and content not mentioned in the update.

What happens if a capability doesn't exist yet?

The skill will automatically create a new main specification file for that capability and populate it with the requirements from your delta spec.

Is the sync operation reversible?

The sync edits files directly. It is recommended to use version control (like Git) so you can review and revert changes if the merge does not meet your expectations.

Do I need to install any external tools?

Yes, this skill requires the openspec CLI to be installed and accessible in your environment to list and manage changes.

Synchronizes incremental requirement changes from delta specifications into main project documentation.

This skill enables intelligent merging of delta specifications into a project's main documentation using the OpenSpec framework. Unlike basic text replacement, it performs agent-driven updates that understand requirement contexts—allowing you to add specific scenarios, rename requirements, or update existing definitions without overwriting unrelated content. It streamlines the workflow between proposing changes and finalizing system documentation, ensuring your main specs stay up-to-date while maintaining a clear history of modifications and preserving existing context.
