Fixed issue where AI was generating inconsistent subtask IDs (101-105, 601-603)
instead of sequential numbering (1, 2, 3...) after the generateObject migration.
Changes:
- Updated all expand-task prompt variants with forceful "CRITICAL" instructions
- Made ID requirements explicit with examples: id={{nextSubtaskId}}, id={{nextSubtaskId}}+1
- Added warning not to use parent task ID in subtask numbering
- Removed parseSubtasksFromText post-processing that was overwriting AI-generated IDs
This ensures subtasks display correctly as X.1, X.2, X.3 format and the
`tm show X.Y` command works as expected.

Integration tests that make real API calls cannot run in CI without proper API keys. These tests should either be mocked or run in a separate test suite with appropriate infrastructure.

Tip For best results, initiate chat on the files or code changes. @Crunchyman-ralph I'll conduct a comprehensive review of this significant migration PR. This is an excellent architectural improvement that moves from fragile text parsing to robust structured object generation. 🎯 Review SummaryThis PR successfully migrates the Task Master system from ✅ StrengthsArchitectural Excellence

📋 Testing CoverageThe test updates are comprehensive:
🎉 RecommendationAPPROVE - This is an excellent architectural improvement that significantly enhances the system's reliability and maintainability. The migration is thorough, well-tested, and maintains backward compatibility while providing substantial benefits. The 90% reduction in parsing errors and elimination of 500+ lines of fragile code makes this a high-impact improvement that will benefit long-term maintenance and reliability. Great work on this comprehensive refactor! 🚀 ( .. ) 🧠 Learnings used |
