Documentation Sync Skill

Overview

This skill provides tools and scripts for intelligently synchronizing documentation across the dev-lifecycle-marketplace using Mem0 for relationship tracking.

Purpose: Keep specs, architecture docs, ADRs, and roadmap interconnected and updated when dependencies change.

Key Concepts

Documentation Types

• Specs (specs/{number}-{name}/spec.md) - Feature specifications derived from architecture
• Architecture (docs/architecture/*.md) - System design and component specifications
• ADRs (docs/adr/*.md) - Architecture Decision Records
• Roadmap (docs/ROADMAP.md) - Project timeline and milestones

Relationship Tracking with Mem0

Uses Mem0 OSS (in-memory Qdrant) to store natural language relationships:

# Example memory
"Specification 001 (user-authentication) is derived from
architecture/security.md sections #authentication and #jwt-tokens,
and references ADR-0008 OAuth decision"

Benefits Over JSON/Database

• ✅ Natural language queries: "What specs depend on security.md?"
• ✅ No complex schemas or parsing
• ✅ Easy to understand and modify
• ✅ Conversational interface
• ✅ Local-first (no cloud dependencies)

Available Scripts

1. scripts/sync-to-mem0.py

Scans documentation and populates Mem0 with relationships.

Usage:

python scripts/sync-to-mem0.py

What it does:

• Scans all specs/*/spec.md files
• Parses architecture references: @docs/architecture/file.md#section
• Parses dependencies: dependencies: [001, 002]
• Creates Mem0 memories describing relationships
• Uses user_id for project isolation

2. scripts/query-relationships.py

Query Mem0 for documentation relationships.

Usage:

# Find specs that depend on a doc
python scripts/query-relationships.py "What specs depend on architecture/security.md?"

# Find all references to an ADR
python scripts/query-relationships.py "Which specs reference ADR-0008?"

# Get spec dependencies
python scripts/query-relationships.py "What does spec 001 depend on?"

3. scripts/validate-docs.py

Validate documentation consistency using Mem0.

Usage:

python scripts/validate-docs.py

Checks:

• Broken architecture references
• Missing dependency specs
• Circular dependencies
• Orphaned documents

Templates

Memory Templates

Spec Memory:

Specification {number} ({name}) is derived from architecture/{file}.md
sections {sections}, references ADR-{numbers}, and depends on specs {deps}.
Status: {status}. Last updated: {date}

Architecture Memory:

Architecture document {file}.md has sections: {sections}.
Section {section} is referenced by specs {spec_numbers}

Derivation Chain:

When architecture/{file}.md #{section} changes, these specs need review:
{spec_list}

Examples

Example 1: Sync All Documentation

# Navigate to project root
cd /path/to/dev-lifecycle-marketplace

# Run sync to populate Mem0
python plugins/planning/skills/doc-sync/scripts/sync-to-mem0.py

# Output:
# ✅ Scanned 15 specs
# ✅ Found 42 architecture references
# ✅ Created 57 memories in Mem0
# 📊 Project: dev-lifecycle-marketplace

Example 2: Query Impact of Changes

# Check what's affected by changing security.md
python plugins/planning/skills/doc-sync/scripts/query-relationships.py \
  "What specs are derived from architecture/security.md?"

# Output:
# Specs affected by architecture/security.md:
# - 001-user-authentication (sections: #authentication, #jwt-tokens)
# - 005-admin-panel (sections: #rls-policies)
# - 012-sso-integration (sections: #oauth)

Example 3: Validate Before Deployment

# Check documentation consistency
python plugins/planning/skills/doc-sync/scripts/validate-docs.py

# Output:
# ✅ All architecture references valid
# ⚠️  Spec 003 references missing ADR-0015
# ⚠️  Circular dependency: 007 → 008 → 007
# ❌ Broken reference: @docs/architecture/deleted.md

Configuration

Mem0 Setup

The scripts use Mem0 OSS with in-memory Qdrant (no external dependencies):

config = {
    "vector_store": {
        "provider": "qdrant",
        "config": {
            "collection_name": "documentation",
            "host": "memory",  # in-memory mode
        }
    }
}

Project Isolation

Uses user_id for multi-project support:

# Add memory for specific project
m.add(memory_text, user_id="dev-lifecycle-marketplace")

# Query specific project
m.search(query, user_id="dev-lifecycle-marketplace")

Integration with Planning Commands

This skill powers these planning commands:

• /planning:doc-sync - Populate Mem0 with current documentation
• /planning:impact-analysis <doc-path> - Show what's affected by changes
• /planning:validate-docs - Check documentation consistency
• /planning:update-docs - Interactive sync with user approval

Best Practices

1. Run sync after major changes:

   # After updating architecture or ADRs
   python scripts/sync-to-mem0.py
   

2. Check impact before modifying shared docs:

   # Before editing architecture/security.md
   python scripts/query-relationships.py "specs depending on security.md"
   

3. Validate before commits:

   # Add to pre-commit hook
   python scripts/validate-docs.py || exit 1
   

4. Use natural language queries:

   • "What specs need updating if I change auth flow?"
   • "Which ADRs does spec 001 reference?"
   • "Show me all dependencies for the user module"

Troubleshooting

Mem0 Not Installed

# Install in virtual environment
python -m venv venv
source venv/bin/activate  # or venv\Scripts\activate on Windows
pip install mem0ai

Import Errors

Ensure you're in the virtual environment where Mem0 is installed:

source /tmp/mem0-env/bin/activate
python scripts/sync-to-mem0.py

No Memories Found

Run the sync script first to populate Mem0:

python scripts/sync-to-mem0.py

Future Enhancements

• Auto-sync on file changes (git hooks)
• Web UI for visualizing relationships
• Slack/Discord notifications for affected docs
• Integration with CI/CD for validation
• Export to Mermaid diagrams
• Graph memory for complex relationships
