- Update MCP server with improved tool handling - Add PR description documentation files - Include team communication materials - Update dist files with latest build Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Ignore test output, analysis results, and snapshot files that are generated during local development and testing. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Includes static code analysis, test enhancement suggestions, and project classification caching from main branch. Resolved dist/index.js conflict by rebuilding the GitHub Action bundle. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
BREAKING CHANGE: Peer review no longer defaults to enabled - Fix MCP server peer review to respect config (was defaulting to true) - Improve CLI boolean logic to use nullish coalescing (??) - Both CLI and MCP now consistently respect config.peerReview.enabled - Peer review only runs when explicitly enabled in config or via flag - All other config settings (archDocs, enableStaticAnalysis) remain consistent This ensures predictable behavior: PR Agent only enables features when configured, not by default. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Create multi-root workspace to view both repos simultaneously: - peer-agent: Main PR analysis tool - todo-ai-agents: Target repo for testing and integration Includes recommended extensions and workspace settings. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Fixed MCP server analyze tool to work properly on Windows by adding shell:true to execSync calls. This resolves ENOENT errors when running git commands through the MCP server on Windows systems. Changes: - Added shell:true to all execSync calls in server.ts - Cleaned up obsolete dist files from build refactoring - MCP server now successfully analyzes PRs on Windows Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Created OutputFormatter utility to ensure consistent formatting between CLI terminal output and MCP server markdown output. Both now display: - Project classification - Test suggestions (new tests and enhancements) - Coverage reports - Static analysis results This provides deterministic, consistent output regardless of which interface (CLI or MCP) is used. Changes: - Created src/utils/output-formatter.ts with OutputFormatter class - Supports both 'terminal' (chalk colors) and 'markdown' modes - MCP server now uses shared formatter for test suggestions - Ensures test suggestions appear in MCP output consistently - Matches CLI formatting structure and information density Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
CRITICAL FIX: Prevent silent failures and ensure prompts are always executed Changes: 1. JiraMcpClient: Automatic fallback from MCP to API when MCP fails - Clear error logging at each step - Graceful degradation: MCP → MCP Search → API → null - Shows which method succeeded/failed 2. MCP Server: Show errors to user, don't silently fail - Display peer review errors in output - Explain possible causes and solutions - Continue analysis with base prompts if peer review fails 3. MCP Server: Clearer prompt execution instructions - Explicit "YOU MUST EXECUTE" warnings - Expected token usage guidance (~10k+ tokens) - Step-by-step execution requirements 4. Error handling improvements: - All exceptions logged with context - No silent catch blocks - User always informed of failures This ensures: - Analysis never completely fails due to one component - Users know WHY something failed - Calling LLM knows it MUST execute prompts - Automatic fallback when tools are unavailable Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Refactored the 970-line monolithic server.ts into a clean, maintainable architecture: BEFORE: - src/mcp/server.ts: 970 lines (all logic inline) AFTER: - src/mcp/server.ts: 102 lines (89% reduction, tool registration only) - 13 new modular files with clear separation of concerns NEW STRUCTURE: 1. Constants & Types (2 files) - constants.ts: All magic strings, numbers, messages, tool schemas - types.ts: MCP-specific type definitions 2. Service Classes (6 files - Single Responsibility) - GitService: Git operations (diff, branch, repo info) - DiffParserService: Parse git diff into structured data - TicketExtractorService: Extract Jira ticket references - FormatterService: Format analysis output for MCP responses - DashboardService: HTTP dashboard server lifecycle management - PeerReviewService: Orchestrate peer review workflow 3. Tool Handlers (3 files - One per MCP tool) - AnalyzeTool: Handle analyze tool requests - SaveResultsTool: Handle save results requests - DashboardTool: Handle dashboard requests 4. Index Files (2 files) - services/index.ts: Export all services - tools/index.ts: Export all tool handlers BENEFITS: ✅ SOLID principles: Each class has single responsibility ✅ Testability: Stateless services ready for unit tests ✅ Maintainability: Clear separation of concerns ✅ No magic strings: All constants centralized ✅ Type safety: Proper type definitions throughout ✅ Modularity: Easy to add new tools or services This architecture follows MCP best practices: stateless services, separation of transport from business logic, and clear boundaries for error handling and testing.

…atic analysis output PROBLEM: OutputFormatter.formatStaticAnalysis() was only formatting project classification and test suggestions, but was missing: 1. DevOps cost estimates (devOpsCostEstimates) 2. Coverage reports (coverageReport) These features were running in the agent workflow but not appearing in MCP server output. SOLUTION: - Added formatDevOpsCostEstimates() method to OutputFormatter - Updated formatStaticAnalysis() to include both missing features - Now MCP output has complete feature parity with CLI VERIFICATION: All static analysis tools confirmed running in PROMPT_ONLY mode: ✓ Project classification (src/tools/project-classifier.ts) ✓ Test suggestions (src/tools/test-suggestion-tool.ts) ✓ DevOps cost estimator (src/tools/devops-cost-estimator.ts) ✓ Coverage analyzer (src/tools/coverage-reporter.ts) Workflow analysis confirms CLI and MCP server execute identically: - Both call PRAnalyzerAgent.analyze() with same options - Both run detectAndAnalyzeChangeTypes() for static analysis - Both include all 4 features in output (now that formatter is fixed) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Integrate deterministic DevOps cost analysis into MCP server to show infrastructure cost estimates in analysis output. Changes: - Add devOpsCostEstimates and totalDevOpsCost fields to MCP types - Run analyzeDevOpsFiles in analyze-tool before LLM prompts (deterministic analysis) - Format DevOps cost estimates in MCP output with confidence indicators - Fix Terraform resource extraction regex to handle diff format (+ prefix) - Add debug logging for cost analysis tracing The cost estimation now works consistently in both CLI and MCP modes using the same deterministic code.

Add complete test suite following MCP testing best practices with unit tests for services and integration tests for tools. Unit Tests: - GitService: Git command execution and output parsing (14 tests) - TicketExtractorService: Ticket reference extraction (10 tests) - FormatterService: MCP output formatting (15 tests) - DevOps Cost Estimator: Infrastructure cost estimation (30+ tests) Integration Tests: - AnalyzeTool: Full analysis workflow with git mocks (15 tests) - SaveResultsTool: Database operations and persistence (14 tests) - MCP Server: End-to-end protocol compliance (10 tests) Testing Approach: - Mock all external dependencies (git, filesystem, database) - Test MCP protocol response format compliance - Test PROMPT_ONLY mode (returns prompts, no LLM execution) - Test deterministic analysis (DevOps costs, static analysis) - Test error handling and graceful degradation References: - https://modelcontextprotocol.info/docs/best-practices/ - https://milvus.io/ai-quick-reference/how-do-i-write-unit-tests-for-model-context-protocol-mcp-tools-and-resources - https://github.com/haakco/mcp-testing-framework Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
