To merge OpenSpec delta specifications without losing content, apply ADDED, MODIFIED, REMOVED, and RENAMED requirements to the main specs. This delta-driven operation updates existing blocks and creates new specs while preserving unrelated content.

Delta specs in OpenSpec are change files located at openspec/changes/<change>/specs/<capability>/spec.md. You need to apply them when you want to update main specifications with targeted modifications rather than replacing the entire document.

Yes, when multiple delta changes exist, the tool prompts you to select the specific change to apply. It then reads the selected delta specs and merges the changes incrementally into the main specifications.

Applying ADDED, MODIFIED, REMOVED, and RENAMED requirements to Markdown specs involves reading delta files, comparing them against main specs, and writing the targeted updates. This creates new specs if needed and preserves existing unmentioned content.

Yes, merging delta specs preserves unrelated content in the main OpenSpec specifications. The intelligent merge operation applies targeted updates from the delta files while maintaining an audit trail of existing content not mentioned in the delta.

The best way to automate applying version-controlled specification changes is using an intelligent delta merging tool that reads OpenSpec delta files, compares them with main specs, and writes updates incrementally while prompting for selection when multiple changes exist.
