- **Root Cause**: `fs.readJsonSync()` method doesn't exist in fs-extra with ES modules
- **Fix**: Replaced with `JSON.parse(readFileSync(packageJsonPath, 'utf-8'))`
- **Location**: `src/config.ts:28`
- **Impact**: Server now starts successfully with message "Agent Communication MCP Server v0.4.0 started"
#### Fixed MCP Server Configuration Path
- **Issue**: MCP client couldn't find server executable
- **Root Cause**: Path pointed to `./agent-comm-mcp-server/index.js` instead of compiled output
- **Fix**: Updated path to `./agent-comm-mcp-server/dist/index.js`
- **Location**: `/.mcp.json`
- **Impact**: MCP client can now successfully connect to server

## [0.3.0] - 2025-09-03
### Added
- **Context-Based Task Management**: Complete file system abstraction for agents
- `check_assigned_tasks()` - Returns task IDs and titles only
- `start_task(taskId)` - Activates task, returns context without file paths
- `submit_plan(content)` - Content-only planning submission
- `report_progress(updates)` - Progress marker updates only
- `mark_complete(status, summary)` - Handles completion internally
- `archive_completed_tasks()` - Batch cleanup operation
### Enhanced
- **Complete Documentation Cleanup**: Removed all legacy references for forward-only implementation
- **Context-Only Protocol**: Agents never see file paths or directory structures
- **Auto-Context Injection**: Protocol instructions automatically added to delegated tasks
- **JSON Lines Logging**: All operations logged with metadata for monitoring
- **Session Management**: Connection tracking for multi-agent coordination
### Fixed
- **Documentation Consistency**: All docs now reflect context-based approach only
- **Tool References**: Updated all examples to use context-based tools
- **Protocol Instructions**: Simplified agent guidelines for context-based workflow
## [0.2.0] - 2025-09-02
### Added
- **Advanced Orchestration**: Parallel agent execution with resource locking
- `delegate_task_enhanced` - Resource locking and parallel execution
- `get_execution_plan` - Optimized execution plans with batching
- `claim_resources` - Exclusive access to prevent conflicts
- `release_resources` - Resource cleanup
- `get_task_status` - Orchestration queue monitoring
### Enhanced
- **Resource Conflict Prevention**: Automatic detection and prevention of file conflicts
- **Priority Management**: Support for task priority levels (1-5)
- **Timeout Management**: Configurable task timeouts with automatic cleanup
- **Smart Batching**: Automatic grouping of non-conflicting tasks for parallel execution
- **Performance Monitoring**: Real-time status and resource utilization tracking
### Technical Details
- **Path Pattern Protection**: Use glob patterns for broad resource protection
- **Automatic Lock Cleanup**: Prevents orphaned locks from failed tasks
- **Launch Instructions**: Integration with Claude Code Task tool for orchestrated launches
- **Monitoring Keys**: Unique identifiers for tracking orchestrated task execution
## [0.1.1] - 2025-09-02
### Fixed
- **CRITICAL**: Fixed Jest globals import issues causing VS Code TypeScript integration errors
- Fixed "Cannot find name 'expect'" and "Cannot find name 'describe'" errors in 10 test files
- Updated Jest imports from `import { jest }` to `import { jest, describe, it, expect, beforeEach }`
- Resolved TypeScript type assertion errors in delegate-task.test.ts
- Fixed Promise type mismatches in async test operations
### Added
- **Type Safety Infrastructure**: Comprehensive TypeScript and ESLint improvements
- Added `tsconfig.all.json` for complete workspace analysis including test files
- Added `test:all` script for verbose test execution
- Added `type-check` script for comprehensive TypeScript validation
- Added `type-check:src` and `type-check:tests` scripts for targeted checking
- Added `lint:tests`, `lint:all`, and `lint:fix:all` scripts for comprehensive linting

## [0.1.0] - 2025-09-02
### Fixed
- **CRITICAL**: Fixed MCP response format to match Claude Code expectations
