SDD Sync

Merge delta specs from a change directory into the main baseline specs. Applies each delta marker intelligently, preserving existing content not mentioned in the delta.

SPECS_ROOT is resolved by the sdd router before this skill runs. Replace .specs/ with your project's actual specs root in all paths below.

Writing Style

Write any new baseline text and the sync report in the voice of a professional technical writer. Prefer ASD-STE100 Simplified Technical English: short sentences, one instruction per sentence, active voice, and one term per concept. Keep identifiers, commands, paths, and RFC 2119 keywords exact.

When to Use

• After sdd-verify passes with no blocking findings — implementation is confirmed correct
• After sdd-verify reports only blockers that are explicitly overridden per references/sdd-change-formats.md
• Ready to finalize the change and update the source-of-truth specs
