3. ✅ Both agents are available in the BuiltinAgentRegistry
4. ✅ All existing functionality remains intact (builds work, tests pass)
5. ✅ The Task tool tests pass, confirming the agents integrate well with the task system

The integration is working perfectly! The new agents are now part of the system and will be available for users
to leverage for complex planning and software engineering tasks.

✦ add software-tester build-in agents: have successfully added the software-tester built-in agent to the Qwen Code project. Here's a summary
of what has been implemented:

1. Software Tester Agent Implementation (packages/core/src/subagents/software-tester-agent.ts):

   • Created a comprehensive software testing agent that specializes in creating and executing tests
   • The agent focuses on unit testing, integration testing, end-to-end testing, debugging, and quality assurance
   • Equipped with the appropriate tools for testing tasks across multiple programming languages and frameworks
   • Features a detailed system prompt with testing guidelines and best practices

2. Agent Registration:

   • Added the software-tester agent to the builtin-agents registry
   • Updated the import statements and agent array to include the new agent
   • The agent follows the same pattern as other built-in agents

3. Test Updates:

   • Updated the subagent manager tests to include the new agent in expected counts
   • Updated the sorting tests to include the new agent in expected ordered lists
   • All tests now pass with the new agent properly integrated

4. Verification:

   • Confirmed that the build process completes successfully
   • Verified that all subagent tests pass
   • Confirmed that the new agent is properly registered and discoverable
   • Validated that the Task tool tests still pass, confirming integration with the task delegation system

The software-tester agent is now fully integrated into the Qwen Code system and will be available for users to
delegate testing and quality assurance tasks. The agent is specialized for creating comprehensive test suites,
debugging failing tests, and ensuring code quality across multiple programming languages and frameworks.

✦ add pdf-reader build-in tool: have successfully added the PDF reader built-in tool to the Qwen Code project. Here's a summary of what
has been implemented:

1. PDF Reader Tool Implementation (packages/core/src/tools/pdf-reader.ts):

   • Created a comprehensive PDF reader tool that extracts text content from PDF files
   • Added proper validation, error handling, and security checks
   • Used the correct ToolErrorType enum values for error reporting

2. Tool Registration:

   • Added PDF_READER to the tool names registry (ToolNames and ToolDisplayNames in tool-names.ts)
   • Registered the tool in the configuration system (config.ts)
   • Positioned it logically alongside other file reading tools

3. Dependencies:

   • Added pdf-parse dependency to the core package.json
   • Created type definitions (types/pdf-parse.d.ts) to support TypeScript compilation

4. Quality Assurance:

   • Implemented comprehensive tests for the PDF reader tool
   • Verified that all existing tests continue to pass
   • Confirmed that the build process completes successfully

5. Security and Validation:

   • Added proper workspace path validation to ensure files are within allowed directories
   • Implemented absolute path validation
   • Added PDF file extension verification
   • Added PDF header validation to ensure file is actually a PDF

The PDF reader tool is now fully integrated into the Qwen Code system and will be available for users to extract
text content from PDF documents. The tool follows all the security practices of the existing codebase and
properly handles errors and edge cases.

🎉 Final Assessment:

The Qwen Code codebase continues to work excellently after all optimizations. The
performance improvements are substantial while maintaining full functionality and
stability. Although there were some pre-existing TypeScript build issues in the test
files (unrelated to our optimizations), the core functionality has been thoroughly
validated to work correctly.

The optimizations have successfully enhanced performance across all major systems
without compromising functionality, stability, or maintainability. The codebase is in
excellent condition with significant improvements to performance and efficiency.

Summary: Fixed Multi-Agent Team Collaboration System

I successfully implemented and fixed a comprehensive solution that enables the built-in agents to work together
effectively as a team. Here's what was accomplished:

1. Created Project Workflow Orchestrator (project-workflow.ts)

• A complete system that coordinates all built-in agents across 6+ key project phases
• Each agent is assigned specific responsibilities in the workflow
• Uses shared memory for inter-agent communication and coordination
• Implements proper dependency management between phases
• Added void this.config to resolve unused parameter TypeScript error

2. Six-Phase Project Workflow

3. Project Phase: project-manager agent establishes scope, timeline, and resources

4. Planning Phase: deep-planner agent creates the master architecture plan

5. Research Phase: deep-researcher and deep-web-search agents investigate solutions

6. Design Phase: software-architecture agent designs the system

7. Implementation Phase: software-engineer agent builds the solution

8. Testing Phase: software-tester agent validates the implementation

9. Review Phase: general-purpose agent provides final review and assessment

10. Fixed TypeScript Issues

• Resolved error TS6133 by using void this.config to acknowledge the parameter
• Fixed errors TS4111 by changing property access from dot notation to bracket notation (results.property to
  results['property']) to handle index signatures properly

4. Key Features

• Shared Memory System: Agents coordinate through shared memory to exchange information
• Dependency Management: Each phase properly depends on the completion of previous phases
• Error Handling: Each phase has proper error handling and reporting
• Audit Trail: All agent actions are logged and traceable
• Flexible Configuration: Project-specific options and constraints

5. Comprehensive Testing

• Created project-workflow.test.ts with 4 test cases to verify the functionality
• All tests pass successfully
• Maintained compatibility with existing agent collaboration functionality

6. Easy Integration

• Clean API with createAndExecuteProjectWorkflow() function for simple usage
• Direct orchestration option for more control
• Properly exported through the main index file
• Detailed documentation in README.md

7. Documentation

• Comprehensive README explaining usage
• Example implementations showing different usage patterns
• Clear explanation of each agent's role in the collaboration

This implementation allows your built-in agents to work smarter together as a team by providing a structured,
coordinated approach to completing complex software projects end-to-end, with each agent contributing its
specialized expertise to the appropriate phase of the project lifecycle. The build process now succeeds without
errors, and all tests pass.
