2. Retrieval Algorithm Validation

Test Setup

Test Script: src/reasoningbank/test-retrieval.ts

Test Data: 5 synthetic memories across 3 domains (test.web, test.api, test.db)

Retrieval Results

Query 1: "How to handle CSRF tokens in web forms?" (domain: test.web)

Retrieved 6 candidates:
  1. CSRF Token Handling (conf: 0.88, age: 0d)
  2. Authentication Cookie Validation (conf: 0.82, age: 0d)
  3. Form Validation Before Submit (conf: 0.75, age: 0d)

Query 3: "Database error recovery" (domain: test.db)

Retrieved 2 candidates:
  1. Database Transaction Retry Logic (conf: 0.86, age: 0d)

Scoring Algorithm Verification

Formula: score = α·sim + β·recency + γ·reliability

Parameters (from config):

  • α = 0.65 (semantic similarity weight)
  • β = 0.15 (recency weight via exponential decay)
  • γ = 0.20 (reliability weight from confidence × usage)
  • δ = 0.10 (diversity penalty for MMR selection)

Recency Decay: exp(-age_days / 45) with 45-day half-life

Reliability: min(confidence, 1.0) bounded by confidence score

Cosine Similarity Test

Cosine similarity (identical vectors): 1.0000
Cosine similarity (different vectors): 0.0015
   ✅ Identical vectors have similarity ≈ 1.0
   ✅ Different vectors have lower similarity

Implementation: Normalized dot product with magnitude calculation

5. Integration Points

Claude Flow Memory Space

Database Path: .swarm/memory.db

Integration Strategy:

  • ✅ Extends existing patterns table with type='reasoning_memory'
  • ✅ No breaking changes to existing memory system
  • ✅ Shares performance_metrics table for unified observability
  • ✅ Compatible with existing session state and namespace features

Hooks Integration (Not Yet Implemented)

Pre-Task Hook (hooks/pre-task.ts - to be implemented):

  1. Retrieve top-k relevant memories for task query
  2. Inject memories into system prompt
  3. Log retrieval metrics

Post-Task Hook (hooks/post-task.ts - to be implemented):

  1. Capture trajectory from agent execution
  2. Judge trajectory (Success/Failure)
  3. Distill new memories from trajectory
  4. Check consolidation trigger threshold
  5. Run consolidation if needed

Configuration: Add to .claude/settings.json:

{
  "hooks": {
    "preTaskHook": {
      "command": "tsx",
      "args": ["src/reasoningbank/hooks/pre-task.ts", "--task-id", "$TASK_ID", "--query", "$QUERY"],
      "alwaysRun": true
    },
    "postTaskHook": {
      "command": "tsx",
      "args": ["src/reasoningbank/hooks/post-task.ts", "--task-id", "$TASK_ID"],
      "alwaysRun": true
    }
  }
}
