Does it require external tools?

Yes, this skill requires the OpenSpec CLI to be installed and accessible in your development environment.

How does it handle ambiguous change names?

If a change name isn't specified or is unclear, the skill will list available changes via the OpenSpec CLI and prompt the user for selection.

Can I use this for new features?

Absolutely; if a capability doesn't exist in the main specs yet, the skill will automatically create a new specification file for it.

What is the primary purpose of OpenSpec Sync Specs?

It automates the process of merging incremental changes (deltas) from a specific feature or branch into the main project specification files.

Does this skill overwrite my existing documentation?

No, it uses intelligent merging to only apply specific changes like adding scenarios or renaming requirements while preserving content not mentioned in the delta.

Synchronizes incremental specification changes with main project documentation to maintain an up-to-date source of truth.

The openspec-sync-specs skill enables Claude to intelligently merge delta specifications into a project's main documentation suite. By parsing specific markers for added, modified, or removed requirements, it automates the tedious task of updating comprehensive spec files without overwriting existing context. This is particularly useful in agile development workflows where requirements evolve rapidly, allowing developers and product owners to maintain a single source of truth that reflects the latest feature changes while preserving historical project knowledge.
