laurigates/blueprint-sync

Check the status of generated content and offer options for modified or stale files.

When to Use This Skill

| Use this skill when... | Use blueprint-promote instead when... | |---|---| | You want to detect stale or modified generated rules/skills | You've decided to keep one specific edited rule (single artifact) | | You're reconciling drift between .claude/rules/ and the manifest | You want to acknowledge modifications and stop sync warnings | | You want regenerate/promote/keep options for many files at once | Use blueprint-generate-rules instead to (re)generate from PRDs | | You preview status with --dry-run before changing anything | Use blueprint-sync-ids instead for ID assignment, not content drift |

Flags

| Flag | Description | |------|-------------| | --dry-run | Preview sync status report without interactive prompts or file modifications |

Steps

Purpose:

• Detect when generated skills/commands have been manually modified
• Detect when source PRDs have changed (making generated content stale)
• Offer appropriate actions: regenerate, promote to custom, or keep as-is

1. Read manifest:

   cat docs/blueprint/manifest.json
   

   • Extract generated.rules section
   • If no generated content, report "Nothing to sync"

2. Check each generated rule: For each rule in manifest.generated.rules:

   a. Verify file exists:

   test -f .claude/rules/{name}.md
   

   b. Hash current content:

   sha256sum .claude/rules/{name}.md | cut -d' ' -f1
   

   c. Compare hashes:

   • If content_hash matches → status: current
   • If content_hash differs → status: modified

   d. Check source freshness (for rules from PRDs):

   • Hash current PRD content
   • Compare with source_hash in manifest
   • If differs → status: stale

3. Display sync report:

   Generated Content Sync Status
   
   Rules (.claude/rules/):
   ✅ architecture-patterns.md: Current
   ⚠️ testing-strategies.md: Modified locally
   🔄 implementation-guides.md: Stale (PRDs changed)
   ✅ quality-standards.md: Current
   
   Summary:
   - Current: 3 files
   - Modified: 1 file (user edited)
   - Stale: 1 file (source changed)
   

4. If --dry-run: Output the sync report from Step 3 and exit. Skip all remaining steps.

5. For modified content, offer options:

   question: "{name} has been modified locally. What would you like to do?"
   options:
     - label: "Keep modifications"
       description: "Mark as acknowledged, preserve your changes"
     - label: "Discard modifications (regenerate)"
       description: "Overwrite with fresh generation from PRDs"
     - label: "View diff"
       description: "See what changed before deciding"
     - label: "Skip this file"
       description: "Leave as-is for now"
   

   Based on selection:

   • "Keep modifications" → Update content_hash to current, mark as acknowledged
   • "Regenerate" → Regenerate this rule from PRDs
   • "View diff" → Show diff then re-ask
   • "Skip" → Continue to next file

6. For stale content, offer options:

   question: "{name} is stale (PRDs have changed). What would you like to do?"
   options:
     - label: "Regenerate from PRDs (Recommended)"
       description: "Update with latest patterns from docs/prds/"
     - label: "Keep current version"
       description: "Mark as current without regenerating"
     - label: "View what changed in PRDs"
       description: "See PRD changes before deciding"
     - label: "Skip this file"
       description: "Leave stale for now"
   

   Based on selection:

   • "Regenerate" → Regenerate this rule from PRDs
   • "Keep" → Update source_hash to current, mark as current
   • "View" → Show PRD diff then re-ask
   • "Skip" → Continue to next file

7. Update manifest after changes:

   • Update content_hash for regenerated files
   • Update source_hash if PRD changes acknowledged
   • Update status field appropriately

8. Final report:

   Sync Complete
   
   Actions taken:
   - testing-strategies.md: Modifications acknowledged
   - implementation-guides.md: Regenerated from PRDs
   
   Current state:
   - 4 generated rules (all current)
   
   Manifest updated.
   

Tips:

• Run /blueprint:sync periodically to check for drift
• Acknowledge modifications you want to keep
• Regenerating will overwrite local changes
• Stale content still works, but may miss new patterns from PRDs
