openspec-sync-specs

To merge delta specs safely, this Skill reads delta files and applies ADDED, MODIFIED, REMOVED, and RENAMED items to main specs using guardrails that preserve existing content. It outputs a consolidated spec state for your review.

Synchronizing multiple delta specification changes is handled by prompting you to select a specific change name when ambiguity exists. The Skill then processes the selected delta updates to merge them efficiently into the corresponding main specs.

Yes, applying delta updates includes built-in guardrails that preserve existing content not mentioned in the delta. The operation produces a summary of updates so you can review what was modified, added, or removed.

Yes, you can selectively apply changes because the Skill prompts for change selection when multiple delta changes exist. This agent-driven merging allows intelligent updates like adding a scenario without copying an entire requirement.

The primary limitation is handling ambiguity; when multiple changes exist, the process pauses to prompt for change selection rather than auto-merging. It focuses on preserving existing content, meaning you must manually review the consolidated spec state output.

Agent-driven spec synchronization allows intelligent merging by directly reading delta specs and editing main specs. This enables contextual updates like adding a single scenario without copying an entire requirement, which standard file merges cannot achieve.
