# OpenSpec Archive Skill

Use **`/opsx:archive`** to finalize a completed change. Archives by merging delta specs into the main `openspec/specs/` directory and moving the change folder to `openspec/changes/archive/`.

## When to Use

- Implementation is complete and verified.
- The user says "archive", "finish", "done with this change", "wrap up".
- After running **openspec-verify** (optional but recommended).

## Prerequisites

- **Change exists** with artifacts and (ideally) completed tasks.

## Workflow

1. **Run archive**
   - `/opsx:archive` — archive the current/inferred change.
   - `/opsx:archive <change-name>` — archive a specific change.

2. **What happens**
   1. Checks artifact completion status and task completion (warns if incomplete).
   2. Offers to sync delta specs if not already synced (see **openspec-sync**).
   3. Merges delta specs into `openspec/specs/` (ADDED / MODIFIED / REMOVED sections).
   4. Moves the change folder to `openspec/changes/archive/YYYY-MM-DD-<name>/`.

3. **All artifacts preserved**
   - The full change context (proposal, design, tasks, specs) is preserved in the archive for audit trail.

## Delta Spec Merge Rules

| Section | What happens |
|---------|--------------|
| `## ADDED Requirements` | Appended to main spec |
| `## MODIFIED Requirements` | Replaces existing requirement in main spec |
| `## REMOVED Requirements` | Deleted from main spec |

## Outputs

- Delta specs merged into `openspec/specs/`.
- Change moved to `openspec/changes/archive/YYYY-MM-DD-<name>/`.

## Next Steps

- Start a new change with **openspec-new**.
- The main specs now reflect the changes — future changes build on the updated source of truth.

## Troubleshooting

- **"Incomplete tasks"**: Archive warns but does not block. Decide whether to complete tasks first or archive as-is.
- **"Delta specs not synced"**: Archive will prompt to sync; or run **openspec-sync** beforehand.
- **Multiple changes to archive**: Use **openspec-bulk-archive** instead.
