To merge delta specs into main specs, use a guided workflow that reads both sets and intelligently applies ADDED, MODIFIED, REMOVED, and RENAMED changes to synchronize the primary specifications.

A delta spec captures incremental changes that have diverged from the main specifications, allowing you to apply targeted updates to the primary spec set without archiving every individual change manually.

You can apply modified and removed updates by running an openspec merge, which evaluates the delta changes and applies them to the main specification set while ensuring idempotent, non-destructive results.

Merging delta specs provides guided, non-destructive updates with content preservation, ensuring the primary specifications stay up-to-date while prompting for change names when needed to protect existing data.

Yes, synchronizing delta specs with main specs ensures idempotent results, meaning applying the same delta changes multiple times yields the same final specification state without duplicating or corrupting data.

You need to synchronize delta specifications when your delta specs have diverged from the main specifications and you want a guided workflow to evaluate and apply those incremental updates to keep the primary specs current.
