This file is byte-identical to the first copy the registry indexed, one of 4 indexed copies. Same content hash, so the same checks give both the same grade.
openspec-sync-specs from yazelin/ching-tech-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Sync delta specs from a change to main specs.
This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
**Steps**
1. **If no change name provided, prompt for selection**
Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
Show changes that have delta specs (under `specs/` directory).
**IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
2. **Find delta specs**
Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
Each delta spec file contains sections like:
- `## ADDED Requirements` - New requirements to add
- `## MODIFIED Requirements` - Changes to existing requirements
- `## REMOVED Requirements` - Requirements to remove
- `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
…
The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
