How do I ensure the changes are correct?

Claude will provide a summary of all added, modified, or removed requirements after the sync. It is recommended to use Git to review and commit these changes.

Does this skill require external dependencies?

Yes, this skill requires the OpenSpec CLI to be installed in your environment to list and manage the underlying specification changes.

What is a delta spec in OpenSpec?

A delta spec is a markdown file that describes specific incremental changes—additions, modifications, or removals—to a requirement without needing to redefine the entire document.

What happens if a capability spec doesn't exist yet?

If a main spec file does not exist for a capability, the skill will automatically create it and populate it with the requirements defined in the delta spec.

Does this skill overwrite my existing documentation?

No, the skill uses intelligent merging to only update the specific requirements or scenarios mentioned in the delta spec, preserving all other existing content.

Syncs incremental requirement changes from delta specifications to main project documentation using intelligent merging.

This skill automates the process of updating master project specifications with incremental changes (deltas) defined in the OpenSpec format. It enables Claude to act as an agent that reads specific modifications—such as added, renamed, or deleted requirements—and merges them intelligently into the core documentation files. By preserving existing content and only applying relevant updates like new scenarios or description tweaks, it ensures that project requirements remain synchronized with development progress without manual copy-pasting or risky file overwriting.
