feat: Add Issue Writer and Issue Fixer modes with comprehensive workflows

[hannesrudolph]

Description

This PR introduces two new specialized modes for GitHub issue management:

🔧 Issue Fixer Mode

• Implements comprehensive workflow for fixing GitHub issues and feature requests
• Includes detailed step-by-step processes from issue analysis to PR creation
• Integrates with GitHub MCP tools for seamless issue and PR management
• Supports both bug fixes and feature implementations
• Includes PR review workflow for handling feedback

📝 Issue Writer Mode

• Creates well-structured GitHub issues for bug reports and feature requests
• Includes comprehensive workflow for gathering context and requirements
• Follows GitHub issue templates and best practices
• Integrates with codebase exploration for accurate issue creation

Key Features

• Comprehensive Workflows: Detailed XML-based rule files defining step-by-step processes
• GitHub MCP Integration: Full integration with GitHub tools for issues, PRs, and reviews
• Best Practices: Coding standards, testing guidelines, and communication patterns
• Error Handling: Robust workflows that handle edge cases and failures
• Documentation: Clear guidelines for each workflow step

How It Works

Issue Fixer Workflow

1. Context Retrieval: Gets issue/PR details and comments
2. Requirement Analysis: Analyzes acceptance criteria and constraints
3. Implementation Planning: Creates detailed implementation plan
4. Codebase Exploration: Uses semantic search to understand existing code
5. Solution Implementation: Implements fixes following project patterns
6. Verification: Ensures all acceptance criteria are met
7. Testing: Runs comprehensive test suites
8. Documentation: Creates detailed summary of changes
9. PR Preparation: Prepares comprehensive PR description
10. PR Creation: Creates and links PR to original issue

Issue Writer Workflow

1. Problem Understanding: Analyzes the problem or feature request
2. Codebase Investigation: Explores relevant code and dependencies
3. Context Gathering: Collects all necessary technical context
4. Issue Creation: Creates well-structured GitHub issue with templates
5. Validation: Ensures issue meets quality standards

Testing

• All existing tests pass
• Linting rules pass
• Mode definitions are valid
• Rule files are properly structured
• GitHub MCP tool integration is correctly configured

Requirements

Important: These modes require the GitHub MCP server to be installed and configured for full functionality.

Usage

Users can now:

1. Select "🔧 Issue Fixer" mode to work on GitHub issues and implement fixes
2. Select "📝 Issue Writer" mode to create comprehensive GitHub issues
3. Benefit from guided workflows with detailed instructions at each step
4. Leverage GitHub MCP integration for seamless issue and PR management

Both modes follow the established Roo Code patterns and integrate seamlessly with the existing mode system.

Important

Adds Issue Fixer and Issue Writer modes with detailed workflows for GitHub issue management and integration with GitHub MCP tools.

• Behavior:
  • Adds Issue Fixer mode for fixing issues and creating PRs, with a 10-step workflow in .roo/rules-issue-fixer/1_Workflow.xml.
  • Adds Issue Writer mode for creating issues, with a 7-step workflow in .roo/rules-issue-writer/1_workflow.xml.
  • Integrates both modes with GitHub MCP tools for seamless issue and PR management.
• Files Added:
  • .roo/rules-issue-fixer/1_Workflow.xml to 9_pr_review_workflow.xml for Issue Fixer mode.
  • .roo/rules-issue-writer/1_workflow.xml to 5_github_mcp_tool_usage.xml for Issue Writer mode.
  • Updates .roomodes to include new modes.
• Workflows:
  • Issue Fixer: Context retrieval, implementation planning, codebase exploration, solution implementation, verification, testing, summary preparation, PR creation.
  • Issue Writer: Issue type determination, information gathering, GitHub discussion search, codebase exploration, issue drafting, user confirmation, issue creation.
