Testing (Todos 11, 12, 13) - [ ] Add unit tests for authentication flow (#11) - [ ] Add tests for retry logic (#12) - [ ] Add integration tests for smart name matching (#13) ## Agent Assignments ### Agent 1: Code Quality Specialist **Mission**: Handle Priority 1 quick fixes **Files to modify**: - `src/tools/portfolio/submitToPortfolioTool.ts` - Create new config file for constants **Tasks**: #2, #3, #10 ### Agent 2: Refactoring Specialist **Mission**: Break down the large execute method **Files to modify**: - `src/tools/portfolio/submitToPortfolioTool.ts` **Tasks**: #4 ### Agent 3: Security Specialist **Mission**: Implement security enhancements **Files to modify**: - `src/index.ts` - `src/tools/portfolio/submitToPortfolioTool.ts` **Tasks**: #5, #7, #14 ### Agent 4: Performance Specialist **Mission**: Optimize API usage and performance **Files to modify**: - `src/tools/portfolio/submitToPortfolioTool.ts` **Tasks**: #6, #8, #9, #15 ### Agent 5: Testing Specialist **Mission**: Add comprehensive test coverage **Files to create/modify**: - Test files for authentication, retry logic, and smart matching **Tasks**: #11, #12, #13 ### Agent 6: Review Specialist **Mission**: Review all changes from other agents for quality and consistency **Responsibilities**: - Verify all changes maintain backward compatibility - Ensure code follows project patterns - Check for security implications - Validate test coverage - Confirm no regressions - Final approval before push ## Progress Tracking ### Agent 1 Progress (Code Quality) - Status: COMPLETED - Current task: All Priority 1 tasks completed - Completed: - ✅ Created portfolio-constants.ts config file for all timeout values and magic numbers - ✅ Extracted hardcoded timeout value 30000ms to getValidatedTimeout() function - ✅ Extracted magic number 10 * 1024 * 1024 to FILE_SIZE_LIMITS.MAX_FILE_SIZE - ✅ Extracted retry delay calculation to calculateRetryDelay() function - ✅ Replaced 'metadata: any' with PortfolioElementMetadata interface - ✅ Made timeout configurable via DOLLHOUSE_GITHUB_API_TIMEOUT environment variable - ✅ Updated all similarity scores and max suggestions to use SEARCH_CONFIG constants - ✅ All existing tests passing (148/148 portfolio-related tests pass) - Notes: - All changes maintain backward compatibility - Environment variables have sensible defaults - Added validation helpers for timeout bounds - Updated config index.ts to export new constants ### Agent 2 Progress (Refactoring) - Status: COMPLETED - Current task: All refactoring tasks completed - Completed: - ✅ Analyzed execute method structure and identified 8 logical sections for extraction - ✅ Extracted parameter validation and normalization logic into validateAndNormalizeParams() - ✅ Extracted authentication checking logic into checkAuthentication() - ✅ Extracted content discovery and type detection logic into discoverContentWithTypeDetection() - ✅ Extracted file validation and security checks into validateFileAndContent() - ✅ Extracted metadata preparation logic into prepareElementMetadata() - ✅ Extracted GitHub repository preparation logic into setupGitHubRepository() - ✅ Extracted element submission and response formatting into submitElementAndHandleResponse() - ✅ Added comprehensive JSDoc comments for all new private methods - ✅ Maintained identical functionality - all tests passing (17/17 portfolio tests pass) - ✅ Achieved 78% line reduction in main execute method (278 → 62 lines) - Notes: - Execute method reduced from 278 lines to 62 lines (216 line reduction) - Created 6 focused private methods with single responsibilities - All methods have proper error handling and return type safety - Maintained backward compatibility and existing API contracts - Each extracted method has clear JSDoc documentation ### Agent 3 Progress (Security) - Status: COMPLETED - Current task: All security enhancement tasks completed - Completed: - ✅ **Task #5 - Token Expiration Checks**: Implemented validateTokenBeforeUsage() method with comprehensive validation - Added format validation before API calls - Implemented GitHub API validation to check token expiration and permissions - Added token freshness detection using rate limit headers - Integrated validation into both portfolio creation and collection submission flows - Added comprehensive security event logging for audit trails - Graceful handling of rate-limited validation attempts - ✅ **Task #7 - Path Validation**: Created validatePortfolioPath() method with enhanced security - Comprehensive path traversal prevention (../, \\..\\, etc.) - Control character and null byte detection - Suspicious pattern detection (hex encoding, template literals, etc.) - Platform-specific path length validation (Windows: 260 chars, Unix: 4096 chars) - File extension whitelist validation (.md, .json, .yml, .yaml, .txt only) - Filename character validation (alphanumeric + safe special characters only) - Path normalization with security checks - Integrated into validateFileAndContent() method - ✅ **Task #14 - Token Refresh Logic**: Implemented smart token management for long operations - Created manageTokenForLongOperation() method for different operation types - Added token aging detection and refresh recommendations - Implemented formatTokenRefreshGuidance() for user guidance - Enhanced error handling with token-specific troubleshooting steps - Added operation-specific token management (portfolio_creation, collection_submission, file_upload) - Graceful degradation when tokens are near expiration - User-friendly guidance for OAuth vs Personal Access Token refresh procedures - Notes: - All 148 portfolio-related tests passing (100% backward compatibility maintained) - Security enhancements provide defense-in-depth without impacting user experience - Token validation includes intelligent caching to avoid rate limit abuse - Path validation covers Windows and Unix attack vectors comprehensively - Token management provides proactive guidance rather than reactive failures - All security events logged to SecurityMonitor for audit compliance ### Agent 4 Progress (Performance) - Status: NOT STARTED - Current task: - Completed: - Notes: ### Agent 5 Progress (Testing) - Status: NOT STARTED - Current task: - Completed: - Notes: ### Agent 6 Progress (Review) - Status: NOT STARTED - Current task: - Completed: - Notes: ## Coordination Notes - All changes should be made to the existing PR #639 branch - Maintain backward compatibility - Keep changes focused and minimal - Test thoroughly before pushing -
