WW Consolidate Skill

Manage memory consolidation in World Weaver - the process of organizing, clustering, and optimizing stored memories.

Purpose

Memory consolidation mirrors biological memory processes:

• Clustering: Group similar episodes into themes
• Strengthening: Reinforce frequently co-accessed memories
• Decay: Apply FSRS stability decay
• Extraction: Identify new entities and skills from episodes
• Pruning: Remove orphaned or stale memories

When to Use

Invoke this skill when:

• Many new episodes accumulated (>50)
• Memory search feels slow or noisy
• User requests consolidation
• Before archiving old memories
• After major project milestone

MCP Tools Used

mcp__ww-memory__consolidate_now    - Run consolidation
mcp__ww-memory__memory_stats       - Get system metrics
mcp__ww-memory__get_provenance     - Check memory lineage

Consolidation Types

Light Consolidation

Fast, safe, run frequently.

Operations:

1. Update FSRS stability scores
2. Apply Hebbian strengthening to co-accessed pairs
3. Normalize relationship weights (fan-out correction)
4. Prune orphaned relationships

Duration: 2-10 seconds Frequency: Daily or after 20+ new episodes

Full Consolidation

Thorough, compute-intensive, run weekly.

Operations: All of light consolidation, plus:

1. HDBSCAN clustering of episode embeddings
2. Entity extraction from episode content
3. Skill inference from successful patterns
4. Duplicate entity merging
5. Knowledge graph reindexing

Duration: 30-120 seconds Frequency: Weekly or after 100+ new episodes Requirement: HDBSCAN library installed

Consolidation Workflow

Pre-Consolidation Checks

1. Get current stats: mcp__ww-memory__memory_stats()
2. Check episode count since last consolidation
3. Verify HDBSCAN available (for full consolidation)
4. Estimate consolidation duration

Light Consolidation Process

1. Load all episodes from Qdrant
2. For each episode pair accessed together:
   - Calculate co-access score
   - Update relationship weight in Neo4j
3. Apply FSRS decay to all episodes:
   - R(t, S) = (1 + 0.9 * t/S)^(-0.5)
4. Normalize fan-out weights:
   - Prevent hub nodes from dominating
5. Prune relationships with weight < 0.1

Full Consolidation Process

1. Run light consolidation first
2. Extract episode embeddings
3. Apply stratified sampling if >5000 episodes
4. Run HDBSCAN clustering:
   - min_cluster_size=3
   - metric="cosine"
5. Assign non-sampled episodes to nearest cluster
6. For each cluster:
   - Extract common entities (rule-based or LLM)
   - Identify successful patterns
   - Generate candidate skills
7. Merge duplicate entities:
   - Same name, similar embedding
8. Rebuild Neo4j indexes

Running Consolidation

Via MCP Tool

mcp__ww-memory__consolidate_now(
  consolidation_type="light",  # or "full"
  dry_run=false,               # true to preview only
  session_filter=null          # null for all, or specific session_id
)

Response Format

{
  "status": "completed",
  "type": "light",
  "duration_seconds": 4.2,
  "stats": {
    "episodes_processed": 47,
    "relationships_strengthened": 23,
    "relationships_pruned": 5,
    "stability_updates": 35
  },
  "errors": []
}

Monitoring Consolidation Health

Check Stats Before

mcp__ww-memory__memory_stats()

Returns:
{
  "episodes": {"total": 47, "this_session": 12, "avg_stability": 0.72},
  "entities": {"total": 156, "orphaned": 3},
  "skills": {"total": 23, "active": 20},
  "relationships": {"total": 312, "avg_weight": 0.54},
  "last_consolidation": "2025-11-27T10:00:00",
  "episodes_since_consolidation": 15
}

Interpret Metrics

Metric	Healthy	Needs Attention
Episodes since consolidation	< 50	> 100
Orphaned entities	< 5	> 20
Average relationship weight	0.3-0.7	< 0.2 or > 0.9
Average stability	> 0.5	< 0.3

Error Handling

HDBSCAN Not Available

If full consolidation requested but HDBSCAN not installed:
1. Log warning
2. Fall back to light consolidation
3. Report that clustering was skipped
4. Suggest: pip install hdbscan

Memory Error

If HDBSCAN runs out of memory:
1. Catch MemoryError
2. Return all episodes as single cluster
3. Log warning about dataset size
4. Suggest reducing hdbscan_max_samples

Database Errors

If Neo4j/Qdrant operations fail:
1. Log specific error
2. Continue with remaining operations
3. Report partial completion
4. Do not lose data

Output Format

Success Report

**Type**: Light
**Duration**: 4.2s

### Changes
| Metric | Before | After | Delta |
|--------|--------|-------|-------|
| Episodes | 47 | 47 | 0 |
| Relationships | 312 | 307 | -5 (pruned) |
| Avg Weight | 0.48 | 0.54 | +0.06 |
| Avg Stability | 0.68 | 0.65 | -0.03 (decay) |

### Actions Taken
- Strengthened 23 relationship pairs
- Pruned 5 weak relationships
- Updated 47 stability scores

### Recommendations
- Consider full consolidation (15 new entities detected)

Dry Run Report

## Consolidation Preview (Dry Run)

### Would Process
- 47 episodes
- 312 relationships
- 156 entities

### Would Strengthen
- Neo4j ↔ Cypher: 0.7 → 0.82
- Testing ↔ pytest: 0.5 → 0.65

### Would Prune
- 5 relationships with weight < 0.1

### Would Extract (Full Only)
- 3 potential new entities
- 1 potential new skill

*No changes made*

Integration

This skill is called by:

• /consolidate command
• Scheduled maintenance (cron)
• SessionEnd hook (optionally)
• ww-memory agent for maintenance tasks

Best Practices

1. Run light consolidation frequently - Low cost, keeps memory healthy
2. Run full consolidation weekly - More thorough but slower
3. Monitor orphaned entities - Sign of extraction issues
4. Watch stability decay - If too low, episodesm are being forgotten
5. Check after major imports - Large data loads need consolidation
