Archive a finished OpenSpec change and merge its delta specs into openspec/specs. Use for "openspec archive", "opsx archive", or "openspec sync".
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
The tool is `mcp__claudetto-openspec__openspec`. If its schema is not loaded, load it with ToolSearch `select:mcp__claudetto-openspec__openspec`.
1. Pick the change: the name the user gave, else ask from `{action:"status"}`.
2. Call `{action:"archive", change}`. It validates strictly, refuses a change with an unticked task, computes every merge, moves the change to `openspec/changes/archive/YYYY-MM-DD-<name>`, then writes the merged specs. It merges and archives in one step, so there is no separate sync.
3. If it refuses, nothing changed. Show the refusal and stop. Fix the cause (finish or remove the task, correct the delta) and call it again. No option overrides an open task.
4. On success report the archive path and which `openspec/specs/<capability>/spec.md` files changed.
The line at the top of this page pins the label git:20261106.bdc86ad, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
