openspec-sync-specs

To merge delta specs safely, this tool applies changes incrementally with built-in guardrails to prevent data loss. It parses delta changes and updates main specs while strictly preserving existing content structure.

Delta specs represent incremental changes made during a development cycle. You need to sync delta specs when you want to apply these iterations to main product specifications without permanently archiving the change history.

When multiple changes exist, the merge process prompts you to interactively select a specific delta set. You choose the desired delta change name, and the tool targets only that set for merging.

Yes, you can run merges repeatedly because the updates are strictly idempotent. The tool applies delta changes incrementally, ensuring that repeating the merge operation never duplicates existing specification content.

Merging delta specs does not overwrite existing content uncontrollably because the tool enforces strict content preservation and guardrails. It safely applies delta parsing to ensure original main spec data remains intact.
