openspec-sync-specs

To merge delta specs into main specs without losing existing content, apply delta specifications stored under openspec/changes. The process preserves all unrelated content while intelligently applying ADDED, MODIFIED, REMOVED, and RENAMED requirements to the main specifications.

A delta spec sync applies incremental specification changes back into main OpenSpec documents. You need it when changes accumulate under openspec/changes and must be consolidated into the main specs without archiving the original delta files.

To apply ADDED, MODIFIED, and REMOVED requirements to openspec specifications, run the openspec-sync-specs tool. It uses intelligent merging rules to update or create main specs based on the delta changes, ensuring minimal disruption to the overall document.

Yes, you can batch merge multiple delta spec changes using the openspec CLI. The CLI enumerates the available changes under openspec/changes, allowing you to select and apply multiple updates to the main specs in an automation-friendly workflow.

Merging delta specs with openspec does not archive the original delta files. The tool synchronizes the changes into the main specifications while leaving the delta specs intact under the openspec/changes directory for future reference or auditing.

Unrelated content remains fully preserved when syncing delta specs into main specs. The intelligent merging mechanism only targets sections mentioned in the delta, ensuring that existing requirements outside the delta scope are not modified or removed.
