Plan Completion

Completes implementation plans by updating linked design documentation, recording completion metadata, and removing the transitory plan file.

Overview

Plans are ephemeral work tracking (like GitHub issues). When work is done, this skill:

1. Validates completion requirements
2. Updates linked design docs with implementation status
3. Records completion metadata
4. Deletes the plan file (knowledge now lives in design docs)

Philosophy: Plans are temporary. Design docs are permanent.

Quick Start

Complete a plan:

/plan-complete plan-design-linking-phase-1

With custom outcome:

/plan-complete cache-optimization --outcome=partial

Dry run (preview changes):

/plan-complete subagent-integration --dry-run

Parameters

Required

• plan-name: Plan identifier (without .md extension)

Optional

• --outcome: Completion outcome (success, partial, failed) [default: success]
• --dry-run: Preview changes without executing
• --keep: Keep plan file after completion (for reference)

Workflow

High-level completion process:

1. Load plan from .claude/plans/{plan-name}.md
2. Validate completion requirements (status, progress, linked docs exist)
3. Update design docs (status, last-synced, completion metadata)
4. Record completion in design doc frontmatter
5. Delete plan file (unless --keep specified)
6. Generate report of all actions taken

For detailed implementation steps, see supporting documentation below.

Supporting Documentation

When you need detailed information, load the appropriate supporting file:

For Completion Workflow

See instructions.md for:

• Step-by-step completion process
• Design doc update procedures
• Completion metadata format
• Validation requirements
• Error handling and rollback

Load when: Performing completion or need implementation details

For Design Doc Updates

See design-doc-updates.md for:

• Updating status (draft → current, stub → current)
• Recording completion metadata format
• Handling multiple linked design docs
• Last-synced timestamp updates
• Bidirectional link cleanup

Load when: Working with design doc updates or metadata

For Usage Examples

See examples.md for:

• Complete successful implementation
• Partial completion with notes
• Failed implementation (knowledge still valuable)
• Multiple design docs linked
• Dry run preview
• Keep plan file for reference

Load when: User needs examples or clarification

Validation Requirements

Before completion, the skill verifies:

Plan Requirements

• ✅ Plan file exists
• ✅ Status is "completed" or can be set to completed
• ✅ Progress is 100%
• ✅ All required frontmatter fields present
• ✅ Has implements field with design docs

Design Doc Requirements

• ✅ All linked design docs exist
• ✅ Design docs are in appropriate state (draft/stub)
• ✅ Bidirectional links are correct

Implementation Evidence

• ✅ Design docs have been updated with implementation details
• ✅ Last-synced is reasonably recent (< 30 days)
• ✅ Completeness score increased during implementation

What Gets Updated

Design Doc Frontmatter

status: current  # Was: draft or stub
last-synced: 2026-01-18  # Today's date
completeness: 95  # Should be high after implementation

# New completion metadata
completed-plans:
  - name: "plan-design-linking-phase-1"
    completed: "2026-01-18"
    outcome: "success"

Plan File

Deleted (unless --keep specified) because:

• Knowledge now lives in design docs
• Plan was temporary work tracking
• Reduces clutter in .claude/plans/

Error Handling

Plan Not Completed

ERROR: Cannot complete plan with status 'in-progress'

Current state:
  Status: in-progress
  Progress: 75%

Required state:
  Status: completed
  Progress: 100%

Fix: Update plan frontmatter first, then complete

Linked Design Docs Missing

ERROR: Linked design doc not found
Plan implements: design-doc-system/missing-doc.md
Path checked: .claude/design/design-doc-system/missing-doc.md

Fix: Create design doc or fix path in plan frontmatter

Design Doc Already Current

WARNING: Design doc already marked as current
Doc: effect-type-registry/observability.md
Status: current
Last-synced: 2026-01-15

This may indicate the plan was already completed.
Continue anyway? (y/n)

Integration

Works well with:

• /plan-validate - Validate before completing
• /design-sync - Sync design docs before completion
• /design-review - Review updated docs
• /plan-list - Find completed plans

Success Criteria

A successful completion:

• ✅ All linked design docs updated to current status
• ✅ Completion metadata recorded
• ✅ Last-synced timestamps updated
• ✅ Plan file deleted (or kept if requested)
• ✅ Clear completion report generated
• ✅ No broken links remain

Rollback

If something goes wrong during completion:

1. Design doc changes are in git (can revert)
2. Plan file deletion is final (but can recreate if needed)
3. Recommendation: Use --dry-run first for preview
