openspec-sync-specs

To merge delta specs into main specs in openspec, the delta-sync workflow reads changes under openspec/changes/<name>/specs and applies them to openspec/specs. It handles added, modified, removed, and renamed requirements with intelligent merging while preserving unmentioned content.

A delta spec represents proposed changes located under openspec/changes. You need to sync a delta spec when you want to update main specifications with these changes without archiving the original delta change folder.

Yes, you can apply delta changes without archiving the delta. The sync workflow merges specified delta changes directly into main specs idempotently, ensuring running it again yields the same result without duplicating changes or removing the delta.

When multiple delta changes are available, the sync workflow provides guardrails and prompts you to select the specific delta change name. This ensures you explicitly choose which changes to merge into the main specs.

Yes, the spec sync creates a main spec if the corresponding specification is missing. It reads both delta and main specs, applies changes idempotently, and outputs a summary of all updates including newly created files.
