Code Reuse Health Check (Inline Orchestration)

You ARE the orchestrator. Execute this workflow directly without spawning a separate orchestrator agent.

Workflow Overview

Beads Init → Detection → Create Issues → Consolidate by Priority → Close Issues → Verify → Beads Complete

Max iterations: 3 Priorities: high → medium → low Beads integration: Automatic issue tracking

---

Phase 1: Pre-flight & Beads Init

1. Setup directories:

   mkdir -p .tmp/current/{plans,changes,backups}
   

2. Validate environment:

   • Check package.json exists
   • Check type-check and build scripts exist

3. Create Beads wisp:

   bd mol wisp exploration --vars "question=Code duplication scan and consolidation"
   

   IMPORTANT: Save the wisp ID (e.g., mc2-xxx) for later use.

4. Initialize TodoWrite:

   [
     {"content": "Duplication detection", "status": "in_progress", "activeForm": "Detecting duplications"},
     {"content": "Create Beads issues", "status": "pending", "activeForm": "Creating issues"},
     {"content": "Consolidate high priority duplications", "status": "pending", "activeForm": "Consolidating high priority"},
     {"content": "Consolidate medium priority duplications", "status": "pending", "activeForm": "Consolidating medium priority"}
          
          
          
   
   

---

Phase 2: Detection

Invoke reuse-hunter via Task tool:

subagent_type: "reuse-hunter"
description: "Detect all code duplications"
prompt: |
  Scan the entire codebase for code duplications:
  - Duplicated TypeScript interfaces/types
  - Duplicated Zod schemas
  - Duplicated constants and configuration objects
  - Copy-pasted utility functions
  - Similar code patterns that should be abstracted
  - Categorize by priority (high/medium/low)

  Generate: reuse-hunting-report.md

  Return summary with duplication counts per priority.

After reuse-hunter returns:

1. Read reuse-hunting-report.md
2. Parse duplication counts by priority
3. If zero duplications → skip to Phase 7 (Final Summary)
4. Update TodoWrite: mark detection complete

---

Phase 3: Create Beads Issues

For each duplication found, create a Beads issue:

# High - types/schemas duplicated across packages (P2)
bd create "REUSE: {type_name} duplicated in {locations}" -t chore -p 2 -d "{description}" \
  --deps discovered-from:{wisp_id}

# Medium - constants/configs duplicated (P3)
bd create "REUSE: {const_name} duplicated" -t chore -p 3 -d "{description}" \
  --deps discovered-from:{wisp_id}

# Low - utility functions, minor duplications (P4)
bd create "REUSE: {item_name} can be consolidated" -t chore -p 4 -d "{description}" \
  --deps discovered-from:{wisp_id}

Track issue IDs in a mapping for later closure.

Update TodoWrite: mark "Create Beads issues" complete.

---

Phase 4: Quality Gate (Pre-consolidation)

Run inline validation:

pnpm type-check
pnpm build

• If both pass → proceed to consolidation
• If fail → report to user, exit

---

Phase 5: Consolidation Loop

For each priority (high → medium → low):

1. Check if duplications exist for this priority

   • If zero → skip to next priority

2. Update TodoWrite: mark current priority in_progress

3. Claim issues in Beads:

   bd update {issue_id} --status in_progress
   

4. Invoke reuse-fixer via Task tool:

   subagent_type: "reuse-fixer"
   description: "Consolidate {priority} duplications"
   prompt: |
     Read reuse-hunting-report.md and consolidate all {priority} priority duplications.
   
     For each duplication:
     1. Backup files before editing
     2. Determine canonical location (usually shared-types or shared package)
     3. Create/update canonical file with the type/schema/constant
     4. Replace duplicates with imports/re-exports
     5. Log change to .tmp/current/changes/reuse-changes.json
   
     Generate/update: reuse-consolidation-implemented.md
   
     Return: count of consolidated items, count of failed consolidations, list of consolidated item IDs.
   

5. Quality Gate (inline):

   pnpm type-check
   pnpm build
   

   • If FAIL → report error, suggest rollback, exit
   • If PASS → continue

6. Close consolidated issues in Beads:

   bd close {issue_id_1} {issue_id_2} ... --reason "Consolidated to shared-types"
   

7. Update TodoWrite: mark priority complete

8. Repeat for next priority

---

Phase 6: Verification

After all priorities consolidated:

1. Update TodoWrite: mark verification in_progress

2. Invoke reuse-hunter (verification mode):

   subagent_type: "reuse-hunter"
   description: "Verification scan"
   prompt: |
     Re-scan codebase after consolidation.
     Compare with previous reuse-hunting-report.md.
   
     Report:
     - Duplications resolved (count)
     - Duplications remaining (count)
     - New duplications introduced (count)
   

3. Decision:

   • If duplications_remaining == 0 → Phase 7
   • If iteration < 3 AND duplications_remaining > 0 → Go to Phase 2
   • If iteration >= 3 → Phase 7 with remaining items

---

Phase 7: Final Summary & Beads Complete

1. Complete Beads wisp:

   # If all consolidated
   bd mol squash {wisp_id}
   
   # If nothing found
   bd mol burn {wisp_id}
   

2. Create issues for remaining items (if any):

   bd create "REUSE REMAINING: {item_name}" -t chore -p {priority} \
     -d "Not consolidated. May require architectural decision. See reuse-hunting-report.md"
   

3. Generate summary for user:

## Code Reuse Health Check Complete

**Wisp ID**: {wisp_id}
**Iterations**: {count}/3
**Status**: {SUCCESS/PARTIAL}

### Results
- Found: {total} duplications
- Consolidated: {consolidated} ({percentage}%)
- Remaining: {remaining}

### By Priority
- High: {consolidated}/{total}
- Medium: {consolidated}/{total}
- Low: {consolidated}/{total}

### Beads Issues
- Created: {count}
- Closed: {count}
- Remaining: {count}

### Validation
- Type Check: {status}
- Build: {status}

### Artifacts
- Detection: `reuse-hunting-report.md`
- Consolidation: `reuse-consolidation-implemented.md`

4. Update TodoWrite: mark wisp complete

5. SESSION CLOSE PROTOCOL:

   git status
   git add .
   bd sync
   git commit -m "refactor: consolidate {consolidated} duplications ({wisp_id})"
   bd sync
   git push
   

---

Error Handling

If quality gate fails:

Rollback available: .tmp/current/changes/reuse-changes.json

To rollback:
1. Read changes log
2. Restore files from .tmp/current/backups/
3. Re-run workflow

If worker fails:

• Report error to user
• Keep Beads wisp open for manual completion
• Suggest manual intervention
• Exit workflow

If Beads command fails:

• Log error but continue workflow
• Beads tracking is enhancement, not blocker

---

Duplication Categories

Types/Interfaces (shared-types):

• Database types
• API types
• Zod schemas
• Common enums

Constants (shared-types):

• Configuration objects
• MIME types, file limits
• Feature flags

Utilities (shared package or re-export):

• Helper functions
• Validation utilities
• Formatters

Single Source of Truth Pattern:

1. Canonical location: packages/shared-types/src/
2. Other packages: export * from '@package/shared-types/{module}'
3. NEVER copy code between packages
