feat: add /opsx:archive command for archiving completed changes (#451)

TabishB · web-flow · commit b7f5a429de06 · 2026-01-06T17:21:37.000-08:00
Add `/opsx:archive` slash command to complete the OPSX workflow lifecycle.
This command archives completed changes in the experimental workflow with:

- Change selection prompt (if not specified)
- Artifact completion check using `openspec status --json`
- Task completion check (parsing tasks.md for `- [ ]`)
- Spec sync prompt (offers `/opsx:sync` before archiving if specs exist)
- Archive to `openspec/changes/archive/YYYY-MM-DD-&lt;name&gt;/`
- Clear output formatting for success, warnings, and errors

This completes the OPSX command suite:
- /opsx:new - Start a change
- /opsx:continue - Create next artifact
- /opsx:ff - Fast-forward all artifacts
- /opsx:apply - Implement tasks
- /opsx:sync - Sync delta specs
- /opsx:archive - Archive completed change (NEW)

+## Context
+
+The experimental workflow (OPSX) provides a complete lifecycle for creating changes:
+- `/opsx:new` - Scaffold a new change with schema
+- `/opsx:continue` - Create next artifact
+- `/opsx:ff` - Fast-forward all artifacts
+- `/opsx:apply` - Implement tasks
+- `/opsx:sync` - Sync delta specs to main
+
+The missing piece is archiving. The existing `openspec archive` command works but:
+1. Applies specs programmatically (not agent-driven)
+2. Doesn't use the artifact graph for completion checking
+3. Doesn't integrate with the OPSX workflow philosophy
+
+## Goals / Non-Goals
+
+**Goals:**
+- Add `/opsx:archive` skill to complete the OPSX workflow lifecycle
+- Use artifact graph for schema-aware completion checking
+- Integrate with `/opsx:sync` for agent-driven spec syncing
+- Preserve `.openspec.yaml` schema metadata in archive
+
+**Non-Goals:**
+- Replacing the existing `openspec archive` CLI command
+- Changing how specs are applied in the CLI command
+- Modifying the artifact graph or schema system
+
+## Decisions
+
+### Decision 1: Skill-only implementation (no new CLI command)
+
+The `/opsx:archive` will be a slash command/skill only, not a new CLI command.
+
+**Rationale**: The existing `openspec archive` CLI command already handles the core archive functionality (moving to archive folder, date prefixing). The OPSX version just needs different pre-archive checks and optional sync prompting, which are agent behaviors better suited to a skill.
+
+**Alternatives considered**:
+- Adding flags to `openspec archive` (e.g., `--experimental`) - Rejected: adds complexity to CLI, harder to maintain two code paths
+- New CLI command `openspec archive-experimental` - Rejected: unnecessary duplication, agent skills are the OPSX pattern
+
+### Decision 2: Prompt for sync before archive
+
+The skill will check for unsynced delta specs and prompt the user before archiving.
+
+**Rationale**: The OPSX philosophy is agent-driven intelligent merging via `/opsx:sync`. Rather than programmatically applying specs like the regular archive command, we prompt the user to sync first if needed. This maintains workflow flexibility (user can decline and just archive).
+
+**Flow**:
+1. Check if `specs/` directory exists in the change
+2. If yes, ask: "This change has delta specs. Would you like to sync them to main specs before archiving?"
+3. If user says yes, execute `/opsx:sync` logic
+4. Proceed with archive regardless of answer
+
+### Decision 3: Use artifact graph for completion checking
+
+The skill will use `openspec status --change "<name>" --json` to check artifact completion instead of just validating proposal.md and specs.
+
+**Rationale**: The experimental workflow is schema-aware. Different schemas have different required artifacts. The artifact graph knows which artifacts are complete/incomplete for the current schema.
+
+**Behavior**:
+- Show warning if any artifacts are not `done`
+- Don't block archive (user may have valid reasons to archive early)
+- List incomplete artifacts so user can make informed decision
+
+### Decision 4: Reuse tasks.md completion check from regular archive
+
+The skill will parse tasks.md and warn about incomplete tasks, same as regular archive.
+
+**Rationale**: Task completion checking is valuable regardless of workflow. The logic is simple (count `- [ ]` vs `- [x]`) and doesn't need special OPSX handling.
+
+### Decision 5: Move change to archive/ with date prefix
+
+Same archive behavior as regular command: move to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+**Rationale**: Consistency with existing archive convention. The `.openspec.yaml` file moves with the change, preserving schema metadata.
+
+## Risks / Trade-offs
+
+**Risk**: Users confused about when to use `/opsx:archive` vs `openspec archive`
+→ **Mitigation**: Documentation should clarify: use `/opsx:archive` if you've been using the OPSX workflow, use `openspec archive` otherwise. Both produce the same archived result.
+
+**Risk**: Incomplete sync if user declines and has delta specs
+→ **Mitigation**: The prompt is informational; user has full control. They may want to archive without syncing (e.g., abandoned change). Log a note in output.
+
+**Trade-off**: No programmatic spec application in OPSX archive
+→ **Accepted**: This is intentional. OPSX philosophy is agent-driven merging. If user wants programmatic application, use `openspec archive` instead.

+## Why
+
+The experimental workflow (OPSX) provides a schema-driven, artifact-by-artifact approach to creating changes with `/opsx:new`, `/opsx:continue`, `/opsx:ff`, `/opsx:apply`, and `/opsx:sync`. However, there's no corresponding archive command to finalize and archive completed changes. Users must currently fall back to the regular `openspec archive` command, which doesn't integrate with the OPSX philosophy of agent-driven spec syncing and schema-aware artifact tracking.
+
+## What Changes
+
+- Add `/opsx:archive` slash command for archiving changes in the experimental workflow
+- Use artifact graph to check completion status (schema-aware) instead of just validating proposal + specs
+- Prompt for `/opsx:sync` before archiving instead of programmatically applying specs
+- Preserve `.openspec.yaml` schema metadata when moving to archive
+- Integrate with existing OPSX commands for a cohesive workflow
+
+## Capabilities
+
+### New Capabilities
+
+- `opsx-archive-skill`: Slash command and skill for archiving completed changes in the experimental workflow. Checks artifact completion via artifact graph, verifies task completion, optionally syncs specs via `/opsx:sync`, and moves the change to `archive/YYYY-MM-DD-<name>/`.
+
+### Modified Capabilities
+
+(none - this is a new skill that doesn't modify existing specs)
+
+## Impact
+
+- New file: `.claude/commands/opsx/archive.md`
+- New skill definition (generated via `openspec artifact-experimental-setup`)
+- No changes to existing archive command or other OPSX commands
+- Completes the OPSX command suite for full lifecycle management

+## ADDED Requirements
+
+### Requirement: OPSX Archive Skill
+
+The system SHALL provide an `/opsx:archive` skill that archives completed changes in the experimental workflow.
+
+#### Scenario: Archive a change with all artifacts complete
+
+- **WHEN** agent executes `/opsx:archive` with a change name
+- **AND** all artifacts in the schema are complete
+- **AND** all tasks are complete
+- **THEN** the agent moves the change to `openspec/changes/archive/YYYY-MM-DD-<name>/`
+- **AND** displays success message with archived location
+
+#### Scenario: Change selection prompt
+
+- **WHEN** agent executes `/opsx:archive` without specifying a change
+- **THEN** the agent prompts user to select from available changes
+- **AND** shows only active changes (excludes archive/)
+
+### Requirement: Artifact Completion Check
+
+The skill SHALL check artifact completion status using the artifact graph before archiving.
+
+#### Scenario: Incomplete artifacts warning
+
+- **WHEN** agent checks artifact status
+- **AND** one or more artifacts have status other than `done`
+- **THEN** display warning listing incomplete artifacts
+- **AND** prompt user for confirmation to continue
+- **AND** proceed if user confirms
+
+#### Scenario: All artifacts complete
+
+- **WHEN** agent checks artifact status
+- **AND** all artifacts have status `done`
+- **THEN** proceed without warning
+
+### Requirement: Task Completion Check
+
+The skill SHALL check task completion status from tasks.md before archiving.
+
+#### Scenario: Incomplete tasks found
+
+- **WHEN** agent reads tasks.md
+- **AND** incomplete tasks are found (marked with `- [ ]`)
+- **THEN** display warning showing count of incomplete tasks
+- **AND** prompt user for confirmation to continue
+- **AND** proceed if user confirms
+
+#### Scenario: All tasks complete
+
+- **WHEN** agent reads tasks.md
+- **AND** all tasks are complete (marked with `- [x]`)
+- **THEN** proceed without task-related warning
+
+#### Scenario: No tasks file
+
+- **WHEN** tasks.md does not exist
+- **THEN** proceed without task-related warning
+
+### Requirement: Spec Sync Prompt
+
+The skill SHALL prompt to sync delta specs before archiving if specs exist.
+
+#### Scenario: Delta specs exist
+
+- **WHEN** agent checks for delta specs
+- **AND** `specs/` directory exists in the change with spec files
+- **THEN** prompt user: "This change has delta specs. Would you like to sync them to main specs before archiving?"
+- **AND** if user confirms, execute `/opsx:sync` logic
+- **AND** proceed with archive regardless of sync choice
+
+#### Scenario: No delta specs
+
+- **WHEN** agent checks for delta specs
+- **AND** no `specs/` directory or no spec files exist
+- **THEN** proceed without sync prompt
+
+### Requirement: Archive Process
+
+The skill SHALL move the change to the archive folder with date prefix.
+
+#### Scenario: Successful archive
+
+- **WHEN** archiving a change
+- **THEN** create `archive/` directory if it doesn't exist
+- **AND** generate target name as `YYYY-MM-DD-<change-name>` using current date
+- **AND** move entire change directory to archive location
+- **AND** preserve `.openspec.yaml` file in archived change
+
+#### Scenario: Archive already exists
+
+- **WHEN** target archive directory already exists
+- **THEN** fail with error message
+- **AND** suggest renaming existing archive or using different date
+
+### Requirement: Skill Output
+
+The skill SHALL provide clear feedback about the archive operation.
+
+#### Scenario: Archive complete with sync
+
+- **WHEN** archive completes after syncing specs
+- **THEN** display summary:
+  - Specs synced (from `/opsx:sync` output)
+  - Change archived to location
+  - Schema that was used
+
+#### Scenario: Archive complete without sync
+
+- **WHEN** archive completes without syncing specs
+- **THEN** display summary:
+  - Note that specs were not synced (if applicable)
+  - Change archived to location
+  - Schema that was used
+
+#### Scenario: Archive complete with warnings
+
+- **WHEN** archive completes with incomplete artifacts or tasks
+- **THEN** include note about what was incomplete
+- **AND** suggest reviewing if archive was intentional
