Agent Sessions

Major Features

• New Color View: Terminal-inspired view with CLI-style colorized output, role-based filtering (User, Agent, Tools, Errors), and navigation shortcuts. Replaces the old "Terminal" mode with enhanced visual hierarchy and interactive filtering.
• Enhanced Transcript Modes: Renamed "Transcript" to "Plain" view for clarity. Added improved JSON viewer with syntax highlighting and better readability for session inspection.
• View Mode Switching: Quick toggle between Plain, Color, and JSON views with Cmd+Shift+T keyboard shortcut.

Critical Fixes

• Claude Usage Tracking: Fixed compatibility with Claude Code's new usage format change ("% left" vs "% used"). The usage probe now supports both old and new formats with automatic percentage inversion, ensuring accurate limit tracking across all Claude CLI versions.
• Script Consolidation: Unified usage capture scripts via symlink to prevent future divergence. Single source of truth in AgentSessions/Resources/.

Improvements

• Color View Navigation: Added role-specific navigation buttons with circular pill styling and tint-aware colors. Jump between user messages, tool calls, or errors with keyboard shortcuts.
• NSTextView Renderer: Implemented high-performance text rendering with native macOS text selection and smooth scrolling.
• JSON View: Redacted encrypted_content fields for cleaner inspection. Improved syntax coloring stability across mode toggles.
• Debug Mode: Added CLAUDE_TUI_DEBUG environment variable for troubleshooting usage capture issues with raw output dumps.

Technical

• Flexible Pattern Matching: Usage probe now tries multiple patterns ("% left", "% used", "%left", "%used") with fallback to any "N%" format. Future-proofed against CLI format changes.
• Enhanced Testing: Comprehensive test suite for both old and new Claude usage formats with validation of percentage inversion logic.
