Claude Memory

Never solve the same bug twice

A debugging memory system for Claude Code that automatically learns from past incidents and suggests solutions based on similar problems you've already solved.

Features

• Incident Tracking: Store complete debugging incidents with symptoms, root causes, fixes, and verification
• Interactive Verification ✨ NEW: Guided prompts to ensure high-quality incident documentation
• Quality Scoring: Automatic calculation of incident completeness (0-100%)
• Auto-Pattern Extraction ✨ NEW: Automatically extracts patterns after storing 3+ similar incidents
• Enhanced Search ✨ NEW: Multi-strategy search (exact → tag → fuzzy → semantic)
• Batch Operations ✨ NEW: Review incomplete incidents, extract patterns, cleanup old data
• Smart Retrieval: Find similar incidents using keyword-based similarity matching
• Audit Trail Mining: Recover incidents from .claude/audit files when manual storage is missed
• Dual Storage Modes:
  • Local mode: Each project has its own .claude/memory/
  • Shared mode: All projects share ~/.claude-code-debugger/ for cross-project learning
• CLI Access: Command-line interface for quick memory operations
• Programmatic API: Import and use in your TypeScript/JavaScript code

Installation

# npm
npm install @tyroneross/claude-code-debugger

# pnpm
pnpm add @tyroneross/claude-code-debugger

# yarn
yarn add @tyroneross/claude-code-debugger

Global Installation (for CLI access anywhere)

# npm
npm install -g @tyroneross/claude-code-debugger

# pnpm
pnpm add -g @tyroneross/claude-code-debugger

# yarn
yarn global add @tyroneross/claude-code-debugger

Troubleshooting Installation

pnpm store mismatch error: If you see ERR_PNPM_UNEXPECTED_STORE, your project has a local .pnpm-store directory. Fix with:

rm -rf .pnpm-store node_modules
pnpm install

npm/pnpm conflict: If your project uses pnpm (has pnpm-lock.yaml), always use pnpm add instead of npm install.

Quick Start

claude-code-debugger status

# Search memory before debugging
claude-code-debugger debug "Search filters not working"

# Search for specific incidents
claude-code-debugger search "react hooks"

# Suggest patterns to extract
claude-code-debugger patterns

# Extract and store patterns

Programmatic Usage

import {
  debugWithMemory,
  storeDebugIncident,
  checkMemory,
  extractPatterns,
  mineAuditTrail
} from '@tyroneross/claude-code-debugger';

// Before debugging: Check for similar incidents
const result = await debugWithMemory("Search filters not working", {
  min_confidence: 0.7
});

console.log('Session ID:', result.context_used.session_id);

// After fixing: Store the incident
await storeDebugIncident(sessionId, {
  root_cause: {
    description: "Missing useMemo dependency caused infinite re-renders",
    category: "react-hooks",
    confidence: 0.9
  },
  fix: {
    approach: "Added missing dependency to useMemo array",
    changes: ["components/SearchBar.tsx"],
    time_to_fix: 15
  },
  verification: {
    status: 'verified',
    regression_tests_passed: true,
    user_journey_tested: true,
    success_criteria_met: true
  }
});

// Search memory directly
const memory = await checkMemory("infinite render loop", {
  similarity_threshold: 0.5,
  max_results: 5
});

// Extract patterns from incidents
const patterns = await extractPatterns({
  min_incidents: 3,
  min_similarity: 0.7,
  auto_store: true
});

// Mine audit trail
const incidents = await mineAuditTrail({
  days_back: 30,
  auto_store: true,
  min_confidence: 0.7
});

Interactive Verification (New in v1.2.0)

Use interactive prompts to ensure high-quality incident documentation:

import { storeIncident, generateIncidentId } from '@tyroneross/claude-code-debugger';

// Create a minimal incident
const incident = {
  incident_id: generateIncidentId(),
  timestamp: Date.now(),
  symptom: 'Search results not displaying',
  root_cause: {
    description: 'React component issue',
    category: 'react',
    confidence: 0.7
  },
  // ... minimal details
};

// Store with interactive mode - system will prompt for missing details
const result = await storeIncident(incident, {
  interactive: true,  // Enable guided prompts
  validate_schema: true
});

// The system will:
// 1. Check root cause quality (min 50 chars)
// 2. Ask about verification status
// 3. Suggest tags based on symptom
// 4. Calculate quality score
// 5. Show feedback and confirm storage

Quality Scoring:

• Root Cause Analysis: 30%
• Fix Details: 30%
• Verification: 20%
• Documentation (tags, etc): 20%

Quality Targets:

• 🌟 Excellent: ≥75%
• ✅ Good: ≥50%
• ⚠️ Fair: <50%

See Interactive Verification Guide for details.

Configuration

Storage Modes

Local Mode (default)

• Each project has its own .claude/memory/ directory
• Incidents and patterns are project-specific
• Best for: Project-specific debugging context

Shared Mode

• All projects share ~/.claude-code-debugger/ globally
• Learn across all your projects
• Best for: Common patterns that appear in multiple projects

Switch Modes

# Use shared mode for this command
claude-code-debugger status --shared

# Set shared mode via environment variable
export CLAUDE_MEMORY_MODE=shared
claude-code-debugger status

# In code
import { getConfig } from '@tyroneross/claude-code-debugger';

const config = getConfig({
  storageMode: 'shared'
});

Environment Variables

# Storage mode: 'local' or 'shared'
CLAUDE_MEMORY_MODE=shared

# Custom memory path (overrides mode defaults)
CLAUDE_MEMORY_PATH=/custom/path/to/memory

How It Works

1. Incident Structure

Each incident captures:

• Symptom: What the bug looked like
• Root Cause: Why it happened (with confidence score)
• Fix: How it was resolved (approach + file changes)
• Verification: Testing status
• Quality Gates: Security and review status
• Tags: For categorization and search

2. Pattern Extraction

When 3+ similar incidents are detected:

• Automatically extract common characteristics
• Create reusable pattern with solution template
• Track success rate and usage history
• Include caveats for edge cases

3. Retrieval Strategy

Pattern-First Approach:

• Try to match against known patterns (90% confidence)
• If no pattern matches, search incidents (70% confidence)
• Use keyword-based Jaccard similarity
• Prefer recent incidents (90-day window)

4. Audit Trail Mining

Recover incidents from .claude/audit/ files:

• Parses root cause analysis documents
• Extracts error tracking logs
• Converts fix reports into incidents
• Filters duplicates and low-confidence entries

Integration with Claude Code

Prompt for Agents

Include in your agent prompts:

Before debugging, check memory:
- Run: `npx claude-code-debugger debug "symptom description"`
- Review similar incidents and patterns
- Apply known solutions if confidence is high

After fixing:
- Store incident with: `npx claude-code-debugger store`
- Or use programmatic API from TypeScript

Automated Mining

Set up periodic audit mining:

# Weekly cron job to mine audit trail
0 0 * * 0 cd /path/to/project && npx claude-code-debugger mine --days 7 --store

Best Practices

1. Always Check Before Debugging

claude-code-debugger debug "symptom" --threshold 0.7

2. Store Complete Incidents

Include all fields for maximum reuse:

• Root cause with confidence score
• Complete fix description
• Verification status
• Quality gates

3. Extract Patterns Regularly

# Weekly pattern extraction
claude-code-debugger patterns --extract

4. Mine Audit Trail

# Monthly audit mining
claude-code-debugger mine --days 30 --store

5. Use Shared Mode for Common Issues

export CLAUDE_MEMORY_MODE=shared
