# WW Recall Skill

Multi-strategy memory retrieval from World Weaver's tripartite memory system.

## Purpose

Search and retrieve relevant memories from:
1. **Episodic Memory**: Past experiences and events
2. **Semantic Memory**: Knowledge graph entities and relationships
3. **Procedural Memory**: Skills and how-to patterns

## When to Use

Invoke this skill when:
- User asks "what did we do before?", "do you remember?"
- Need context from previous sessions
- Looking for relevant past experiences
- Searching for applicable skills
- Building context for a new task

## MCP Tools Available

```
mcp__ww-memory__recall_episodes    - Search episodic memory
mcp__ww-memory__semantic_recall    - Search knowledge graph
mcp__ww-memory__spread_activation  - Graph traversal from seed
mcp__ww-memory__recall_skill       - Find applicable skills
mcp__ww-memory__query_at_time      - Point-in-time queries
```

## Retrieval Strategies

### Strategy 1: Semantic Search (Default)
Best for: General queries, finding similar content

```
mcp__ww-memory__recall_episodes(
  query: "your search query",
  limit: 10,
  session_filter: null  # All sessions, or specific session_id
)
```

Returns episodes ranked by:
- Semantic similarity to query (40%)
- Recency decay (25%)
- Outcome weight (20%)
- Importance/valence (15%)

### Strategy 2: Temporal Search
Best for: "What did we do last week?", time-bounded queries

```
mcp__ww-memory__recall_episodes(
  query: "project work",
  limit: 10,
  time_filter: {
    after: "2025-11-20T00:00:00",
    before: "2025-11-27T23:59:59"
  }
)
```

### Strategy 3: Knowledge Graph Search
Best for: Finding entities and their relationships

```
mcp__ww-memory__semantic_recall(
  query: "concept or entity name",
  limit: 10,
  include_relationships: true
)
```

### Strategy 4: Spread Activation
Best for: Exploring connections from a known starting point

```
mcp__ww-memory__spread_activation(
  seed_entities: ["Entity A", "Entity B"],
  max_depth: 2,
  min_weight: 0.3
)
```

Returns entities connected to seeds, weighted by relationship strength.

### Strategy 5: Skill Matching
Best for: "How do I...?", finding applicable procedures

```
mcp__ww-memory__recall_skill(
  query: "how to run tests",
  limit: 5,
  check_preconditions: true,
  context: {
    project: "ww",
    working_directory: "/home/aaron/ww"
  }
)
```

### Strategy 6: Point-in-Time Query
Best for: "What did we know at time X?"

```
mcp__ww-memory__query_at_time(
  query: "project status",
  as_of: "2025-11-15T12:00:00"
)
```

## Multi-Strategy Retrieval Workflow

For comprehensive recall, combine strategies:

### 1. Analyze Query
Determine what the user is looking for:
- Past events → Episodic (Strategy 1, 2)
- Concepts/entities → Semantic (Strategy 3, 4)
- How-to procedures → Procedural (Strategy 5)
- Historical state → Temporal (Strategy 6)

### 2. Execute Searches
Run appropriate strategies in parallel:
```
episodes = mcp__ww-memory__recall_episodes(query, limit=5)
entities = mcp__ww-memory__semantic_recall(query, limit=5)
skills = mcp__ww-memory__recall_skill(query, limit=3)
```

### 3. Merge Results
Combine results, removing duplicates by ID.

### 4. Rank Results
Re-rank by overall relevance:
- Query similarity
- Recency
- Source diversity (mix of episode/entity/skill)

### 5. Format Output
Present as structured context:

## Quality Guidelines

When presenting recall results:
- [ ] Show relevance scores when available
- [ ] Include timestamps for temporal context
- [ ] Link related entities when relevant
- [ ] Highlight applicable skills
- [ ] Indicate result source (episodic/semantic/procedural)

## Error Handling

If recall fails:
1. Check MCP server connectivity
2. Try simpler query (fewer filters)
3. Fall back to keyword-based grep of local files
4. Inform user what memories are unavailable
