How does the skill know which changes to apply?

It looks for delta spec files in the OpenSpec changes directory. If no change is specified, it will list available changes and prompt you to select one.

Is the sync operation idempotent?

Yes, running the sync operation multiple times with the same delta will result in the same final state, preventing duplicate entries.

What happens if the main specification file doesn't exist yet?

The skill will automatically create the necessary directory structure and a new spec file, populating it with a purpose section and the new requirements.

Does this skill overwrite my entire specification file?

No, it uses intelligent merging to apply specific changes (like adding a single scenario) while preserving all existing content not mentioned in the delta.

Synchronizes delta specifications into main project specs using intelligent merging logic to update requirements and scenarios.

The OpenSpec Specification Synchronizer is an agent-driven skill designed to manage the evolution of project documentation within the OpenSpec framework. It automates the complex task of merging proposed 'delta' changes into primary specification files, handling additions, modifications, removals, and renames with high precision. Instead of simple file overwriting, this skill performs intelligent partial updates—such as inserting a specific scenario into an existing requirement—ensuring that the main specifications remain accurate and up-to-date without losing existing context or manual formatting.
