| description | Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete. |

Project context preflight before workflow actions: before this skill takes a workflow action, follow the project-constitution skill. Read root CONSTITUTION.md when present, enforce relevant project rules, stop on material conflicts, and follow the strict missing-constitution bootstrap/diagnostic policy. For architecture-sensitive work, also read ARCHITECTURE.md, adr/README.md, and relevant in-force adr/*.md. Read .secrets.local.env only when the current workflow actually needs a listed external system, and never reveal secret values.
Archive a completed change in the experimental workflow.
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
-
If no change name provided, prompt for selection
Run openspec list --json to get available changes. Use the Codex interactive user question tool when available, otherwise a concise Markdown question to let the user select.
Show only active changes (not already archived).
Include the schema used for each change if available.
IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.
-
Check artifact completion status
Git/archive hard gate: run git branch --show-current and git status --short. Archive only from main or an explicitly chosen integrated base branch, with a clean working tree and committed implementation. If implementation is not integrated, stop; verification does not replace merge/integration.
Run openspec status --change "<name>" --json to check artifact completion.
Parse the JSON to understand:
schemaName: The workflow being used
artifacts: List of artifacts with their status (done or other)
If any artifacts are not done:
- Display warning listing incomplete artifacts
- Use Codex interactive user question tool when available, otherwise a concise Markdown question to confirm user wants to proceed
- Proceed if user confirms
-
Check task completion status
Read the tasks file (typically tasks.md) to check for incomplete tasks.
Count tasks marked with - [ ] (incomplete) vs - [x] (complete).
If incomplete tasks found:
- Display warning showing count of incomplete tasks
- Use Codex interactive user question tool when available, otherwise a concise Markdown question to confirm user wants to proceed
- Proceed if user confirms
If no tasks file exists: Proceed without task-related warning.
-
Assess delta spec sync state
Verification gate: before archive, run or confirm a fresh verification report with no CRITICAL issues, then run openspec validate <name> --type change --strict.
Check for delta specs at openspec/changes/<name>/specs/. If none exist, proceed without sync prompt.
If delta specs exist:
- Compare each delta spec with its corresponding main spec at
openspec/specs/<capability>/spec.md
- Determine what changes would be applied (adds, modifications, removals, renames)
- Show a combined summary before prompting
Prompt options:
- If changes needed: "Sync now (recommended)", "Archive without syncing"
- If already synced: "Archive now", "Sync anyway", "Cancel"
If user chooses sync, run the openspec-sync-specs skill or /opsx:sync
prompt directly for change <name> and include the analyzed delta spec
summary as context. Proceed to archive regardless of choice.
-
Perform the archive
Create the archive directory if it doesn't exist:
mkdir -p openspec/changes/archive
Generate target name using current date: YYYY-MM-DD-<change-name>
Check if target already exists:
- If yes: Fail with error, suggest renaming existing archive or using different date
- If no: Move the change directory to archive
mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-
Display summary
Show archive completion summary including:
- Change name
- Schema that was used
- Archive location
- Whether specs were synced (if applicable)
- Note about any warnings (incomplete artifacts/tasks)
Output On Success
## Archive Complete
**Change:** <change-name>
**Schema:** <schema-name>
**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
All artifacts complete. All tasks complete.
Guardrails
- Archive is a mutating lifecycle operation: ask for explicit approval after showing the full plan, archive target, sync state, and git status.
- Do not archive from a dirty tree or before implementation is integrated unless the user gives a one-time override naming the gate; record any override in the archive summary.
- Do not stage, commit, merge, push, or archive without explicit user approval.
- Always prompt for change selection if not provided
- Use artifact graph (
openspec status --change <name> --json) for completion checking
- Don't block archive on warnings - just inform and confirm
- Preserve .openspec.yaml when moving to archive (it moves with the directory)
- Show clear summary of what happened
- If sync is requested, use openspec-sync-specs approach (agent-driven)
- If delta specs exist, always run the sync assessment and show the combined summary before prompting
