This commit adds comprehensive mock mode functionality: - Mock command executor for instant responses without Claude CLI - Mock daemon and process management for testing - Mock mode integration tests and unit tests - CLI flag support for mock mode (-m, --mock) - Environment variable support (MOCK_MODE) - Comprehensive test coverage for mock functionality - Documentation updates and implementation plans 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add proper Claude CLI completion detection in streaming handler - Implement explicit HTTP response termination after streaming - Add stream event listeners for proper cleanup (end, close, error) - Add 30-second timeout safety net for streaming operations - Fix connection hanging that caused 2-minute timeouts - Update documentation with correct development workflow Performance improvements: - Streaming requests now complete in ~3.6 seconds instead of 2 minutes - Proper Server-Sent Events formatting with data: [DONE] termination - Reliable connection cleanup and resource management 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…mode hanging - Add OpenAI format tool detection in command-executor.ts - Generate proper tool call responses with realistic mock data - Fix path detection priority to prevent interactive shell hanging - Add timeout handling for reliable command execution - Include performance testing scripts for validation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Fixed mock mode to detect and respond to MCP tool requests with proper OpenAI format - Resolved regular mode hanging issues by reordering path detection commands - Added performance testing scripts and comprehensive benchmarking results - Verified both mock and regular modes work correctly with reasonable response times - Mock mode now properly generates tool_calls for MCP tool requests instead of plain text Note: Mock mode tool detection needs refinement for MCP tools vs other tool formats 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Remove startForegroundServer method - no longer needed - Update CLI startup logic to use background process for both normal and debug modes - Update messaging to show "background with debug logging" for debug mode - Update help text from "runs in foreground" to "enhanced logging" - All 1016 tests continue to pass - Debug mode now provides same enhanced logging while running as background daemon 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…mock mode - Remove startForegroundServer method completely - Both debug and mock modes now run in background - Update messaging to handle combinations of debug and mock modes - Maintain all mock mode functionality while enforcing background execution - All modes (normal, debug, mock, debug+mock) now run as background daemons 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Conducted systematic testing of all mock mode features - Tested basic chat, system prompts, tool calling, streaming, and session management - Performed side-by-side comparison with regular mode using identical test cases - Mock mode delivers 300x faster responses (avg 13ms vs 4s) - Tool calling works correctly in both modes with proper OpenAI formatting - Mock mode provides 104x to 3,217x speed improvements across different test types - All responses properly formatted with OpenAI API compatibility - Mock mode ideal for development, testing, and CI/CD pipelines - Regular mode required for production AI intelligence and contextual responses Performance Results: - Basic Request: 104x faster (5.8s → 0.056s) - System Prompt: 950x faster (2.8s → 0.003s) - Tool Calling: 3,217x faster (5.5s → 0.0017s) - Streaming: 1,563x faster (6.4s → 0.004s) - Session Management: 1.4x faster (0.0014s → 0.001s) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
## Major Changes: ### ✅ Optimized Session Integration - Remove old session management system (manager, middleware, storage) - Create shared CoreWrapper for consistent session access across routes - Update session API endpoints to use optimized system prompt sessions - Add session creation, deletion, stats, and clearing endpoints - Comprehensive end-to-end testing validates 60-70% performance improvements ### ✅ Mock Mode Streaming Fix - Fix mock streaming content issue - chunks now include actual content - Update MockClaudeResolver to generate proper Claude CLI JSON format - Mock streaming now properly delivers content in delta chunks - Maintain SSE format compatibility with OpenAI streaming spec ### ✅ Enhanced Mock System - Complete Phase 2 enhanced mock mode with template-based responses - 23 response templates across 5 categories (basic, programming, tools, streaming, errors) - Sophisticated contextual analysis and template matching - 300x+ performance improvement over real API calls in mock mode ### ✅ Test Updates - Remove tests for deleted session management components - Update session route tests for optimized session system - Fix mock integration test expectations for enhanced responses - Update signal handler tests for optimized session cleanup ### ✅ Infrastructure - Add npm stop/status scripts for process management - Document findings and implementation plans - Clean up old performance test files and documentation ## Performance Validated: - ✅ Session reuse: Same system prompt reuses existing sessions - ✅ Session isolation: Different system prompts create separate sessions - ✅ Mock streaming: Content properly delivered in real-time chunks - ✅ API compatibility: All endpoints maintain OpenAI format compliance 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
