M.I.M.I.R - Multi-agent Intelligent Memory & Insight Repository

# Changelog - Version 3.1 (2025-10-17) ## 🎉 Major Features ### ✅ Multi-Agent Task Locking System **Prevent race conditions in multi-agent workflows** - Optimistic locking with version tracking - Lock acquisition with configurable timeout (default 5min) - Automatic lock expiration - Query available (unlocked) nodes - Batch cleanup of expired locks **New Tools:** - `memory_lock_node` - Acquire exclusive lock on a node - `memory_unlock_node` - Release lock - `memory_query_available_nodes` - Query unlocked nodes only - `memory_cleanup_locks` - Clean up all expired locks **Implementation:** `src/managers/GraphManager.ts` (4 new methods) **Tests:** 20 integration tests in `testing/multi-agent-locking.test.ts` ### ✅ Parallel Task Execution **Automatic parallel execution based on task dependencies** - Dependency-based batching algorithm - Parallel execution within batches using `Promise.all()` - Sequential batch execution - Explicit parallel group support for PM control - Diamond dependency pattern handling - Circular dependency detection - Intelligent failure handling **Algorithm:** `organizeTasks()` - O(n²) dependency resolution - Automatically organizes tasks into execution batches - Tasks with satisfied dependencies run in parallel - PM can override with explicit `parallelGroup` markers **Implementation:** `src/orchestrator/task-executor.ts` **Tests:** 8 unit + 10 integration tests **Documentation:** `docs/PARALLEL_EXECUTION_SUMMARY.md` ## 📊 Test Suite Enhancements ### Test Coverage: 123 Tests Total - **Product tests (107):** `npm test` - Multi-agent locking: 20 tests - Task executor: 8 unit + 10 integration - Graph operations: 39 tests - File watching: 8 tests - Gitignore: 11 tests - Order processor v1: 11 tests - **Benchmark tests (16):** `npm run test:benchmark` - Order processor v2: 16 debugging exercises - Excluded from main suite (in `testing/agentic/`) ### Test Configuration - ✅ `vitest.config.ts` - Main config (excludes benchmarks) - ✅ `vitest.config.benchmark.ts` - Benchmark-only config - ✅ Sequential test execution for isolation - ✅ Comprehensive mocking for LLM client - ✅ Integration test coverage for multi-agent scenarios ## 📚 Documentation Updates ### New Documentation - **PARALLEL_EXECUTION_SUMMARY.md** - Complete guide to parallel execution - **IMPLEMENTATION_SUMMARY.md** - Updated with v3.1 features - **CHANGELOG_v3.1.md** - This file ### Updated Documentation - **README.md** - Added multi-agent features section, updated tool count - **AGENTS.md** - Added parallel execution guide, updated tool list - All docs now reference 25 total tools (was 16) ## 🔧 Tool Count Update **Total: 25 MCP Tools** (up from 16) - TODO Management: 7 tools - Knowledge Graph: 15 tools (was 11, +4 locking tools) - File Indexing: 4 tools - Utility: 1 tool ## 🏗️ Code Changes ### Modified Files - `src/managers/GraphManager.ts` - Added locking methods (864 lines) - `src/types/IGraphManager.ts` - Added locking interfaces (221 lines) - `src/tools/graph.tools.ts` - Added 4 locking tools (441 lines) - `src/orchestrator/task-executor.ts` - Added parallel execution (577 lines) - `src/index.ts` - Wired up new tools (578 lines) - `package.json` - Updated test scripts ### New Files - `testing/multi-agent-locking.test.ts` - 20 integration tests - `testing/task-executor.test.ts` - 8 unit tests - `testing/task-executor-integration.test.ts` - 10 integration tests - `vitest.config.ts` - Main test configuration - `vitest.config.benchmark.ts` - Benchmark test configuration - `docs/PARALLEL_EXECUTION_SUMMARY.md` - Parallel execution guide ## 📈 Performance ### Parallel Execution Benefits **Example:** 3 tasks with diamond dependencies - **Before (Sequential):** Task1(2s) + Task2(3s) + Task3(3s) = **8s total** - **After (Parallel):** Task1(2s) + Parallel[Task2(3s), Task3(3s)] + Task4(2s) = **~5s total** - **Improvement:** 37.5% faster Real-world benefits depend on: - Number of independent tasks - Task duration variance - Dependency structure - LLM API rate limits ## 🚀 Upgrade Guide ### For Developers 1. Pull latest code 2. Run `npm install && npm run build` 3. Tests should pass: `npm test` (107 tests) 4. Optional: Run benchmarks: `npm run test:benchmark` (16 tests) ### For PM Agents Use parallel groups in chain output: ```markdown ### Task ID: task-1 **Parallel Group:** 1 ... ### Task ID: task-2 **Parallel Group:** 1 ... ``` ### For Worker Agents Claim tasks before executing: ```typescript const locked = await memory_lock_node(taskId, agentId, 300000); if (locked) { // Execute task await memory_unlock_node(taskId, agentId); } ``` ## 🎯 What's Next ### Phase 2: Advanced Multi-Agent (Q4 2025) **See [Phase 2 Implementation Plan](docs/PHASE_2_IMPLEMENTATION_PLAN.md) for detailed roadmap** - Worker agent context isolation (2 weeks) - QC agent verification system (2 weeks) - Adversarial validation loop (1 week) - Agent performance metrics (2 weeks) **Timeline:** 7 weeks + 3 weeks testing/deployment = 10 weeks total ### Phase 3: Advanced RAG (Q1 2026) - Semantic code analysis - Cross-file dependency tracking - Intelligent code search - Context-aware suggestions --- **Version:** 3.1 **Release Date:** 2025-10-17 **Status:** Phase 1 Complete ✅
