# Changelog
## 2025-11-03 - 1.6.1 - fix(context)
Improve context building, caching and test robustness
- EnhancedContext: refactored smart context building to use the analyzer and TaskContextFactory by default; taskType now defaults to 'description' and task-specific modes are applied.
- ConfigManager: simplified analyzer configuration (removed enabled flag) and fixed getAnalyzerConfig fallback shape.
- ContextCache: more robust mtime handling and persistence; tests updated to use real file mtimes so cache validation works reliably.
- LazyFileLoader: adjusted token estimation tolerance and improved metadata caching behavior.
- ContextAnalyzer & trimming pipeline: improved prioritization and trimming integration to better enforce token budgets.
- Tests: relaxed strict timing/boolean checks and made assertions more tolerant (toEqual vs toBe) to reduce false negatives.
## 2025-11-02 - 1.6.0 - feat(context)
Introduce smart context system: analyzer, lazy loader, cache and README/docs improvements
