Refactored the core 'removeTask' function to be fully tag-aware, preventing data corruption.
- The function now correctly reads the full tagged data structure by prioritizing '_rawTaggedData' instead of operating on a resolved single-tag view.
- All subsequent operations (task removal, dependency cleanup, file writing) now correctly reference the full multi-tag data object, preserving the integrity of 'tasks.json'.
- This resolves the critical bug where removing a task would delete all other tags.
Major Issues Fixed:
1. Tag Deletion Bug: Fixed critical issue where creating subtasks would delete other tags
- Root cause: writeJSON function wasn't accepting projectRoot/tag parameters
- Fixed writeJSON signature and logic to handle tagged data structure
- Added proper merging of resolved tag data back into full tagged structure
2. Persistent Migration Notice: Fixed FYI notice showing after every command
- Root cause: markMigrationForNotice was resetting migrationNoticeShown to false
- Fixed migration logic to only trigger on actual legacy->tagged migrations
- Added proper _rawTaggedData checks to prevent false migration detection
3. Data Corruption Prevention: Enhanced data integrity safeguards
- Fixed writeJSON to filter out internal properties
- Added automatic cleanup of rogue properties
- Improved hasTaggedStructure detection logic
Commands Fixed: add-subtask, remove-subtask, and all commands now preserve tags correctly
- show command: Added --tag flag, fixed projectRoot passing to UI functions
- add-task command: Already had proper tag support and projectRoot handling
- Both commands now work correctly with tagged task lists system
- Migration logic works properly when viewing and adding tasks
- Updated subtask 103.5 with progress on high-priority command fixes
- Implements comprehensive tagged task lists system for multi-context task management including core tag management functions (Task 103.11), MCP integration updates, and foundational infrastructure for tagged task operations. Features tag CRUD operations, validation, metadata tracking, deep task copying, and full backward compatibility.
Enhances the MCP server to include 'tagInfo' (currentTag, availableTags) in all tool responses, providing better client-side context.
- Introduces a new 'ContextGatherer' utility to standardize the collection of file, task, and project context for AI-powered commands. This refactors several task-manager modules ('expand-task', 'research', 'update-task', etc.) to use the new utility.
- Fixes an issue in 'get-task' and 'get-tasks' MCP tools where the 'projectRoot' was not being passed correctly, preventing tag information from being included in their responses.
- Adds subtask '103.17' to track the implementation of the task template importing feature.
- Updates documentation ('.cursor/rules', 'docs/') to align with the new tagged task system and context gatherer logic.
- Updated task-structure.md with comprehensive tagged format explanation
- Updated all .cursor/rules/*.mdc files to reflect tagged system
- Completed subtask 103.16: Update Documentation for Tagged Task Lists System
This commit introduces the foundational infrastructure for tagged task lists,
enabling multi-context task management without remote storage to prevent merge conflicts.
CORE ARCHITECTURE:
• Silent migration system transforms tasks.json from old format { "tasks": [...] }
to new tagged format { "master": { "tasks": [...] } }
• Tag resolution layer provides complete backward compatibility - existing code continues to work
• Automatic configuration and state management for seamless user experience
SILENT MIGRATION SYSTEM:
• Automatic detection and migration of legacy tasks.json format
• Complete project migration: tasks.json + config.json + state.json
• Transparent tag resolution returns old format to maintain compatibility
• Zero breaking changes - all existing functionality preserved
CONFIGURATION MANAGEMENT:
• Added global.defaultTag setting (defaults to 'master')
• New tags section with gitIntegration placeholders for future features
• Automatic config.json migration during first run
• Proper state.json creation with migration tracking
USER EXPERIENCE:
• Clean, one-time FYI notice after migration (no emojis, professional styling)
• Notice appears after 'Suggested Next Steps' and is tracked in state.json
• Silent operation - users unaware migration occurred unless explicitly shown
TECHNICAL IMPLEMENTATION:
• Enhanced readJSON() with automatic migration detection and processing
• New utility functions: getCurrentTag(), resolveTag(), getTasksForTag(), setTasksForTag()
• Complete migration orchestration via performCompleteTagMigration()
• Robust error handling and fallback mechanisms
BACKWARD COMPATIBILITY:
• 100% backward compatibility maintained
• Existing CLI commands and MCP tools continue to work unchanged
• Legacy tasks.json format automatically upgraded on first read
• All existing workflows preserved
TESTING VERIFIED:
• Complete migration from legacy state works correctly
• Config.json properly updated with tagged system settings
• State.json created with correct initial values
• Migration notice system functions as designed
• All existing functionality continues to work normally
Part 2 will implement tag management commands (add-tag, use-tag, list-tags)
and MCP tool updates for full tagged task system functionality.
