• New output-mode-setup agent guides you through creating modes with natural language
• Modes can customize response length, tone, format, and workflow preferences
• Project-level modes allow teams to share communication styles

What: New hybrid model option that uses Opus 4.1 in plan mode and Sonnet 4 for execution How to use:

What changed: Improved handling of bash redirections and file descriptors Impact: More reliable command execution with complex shell redirections like 2>&1, 1>/dev/null, and file descriptor routing

What changed: Separated trust dialogs into three distinct categories Impact: Users can now approve bash commands, hooks, and general operations independently, providing finer control over security permissions

What changed: Added shimmer colors to all themes for Claude-related UI elements Impact: Subtle visual feedback improvements with colors like rgb(245,149,117) for light theme and rgb(235,159,127) for dark theme

What changed: All built-in commands now include a source: "builtin" field Impact: Better organization and potential for future command source filtering or custom command sources

What changed: Added first token date tracking and per-organization feature flag caching Impact: Better analytics and feature rollout capabilities for organization-specific features

• Issue: Incorrect import statement for process.cwd
• Cause: Using default import instead of named import
• Resolution: Changed from import ndB from "node:process" to import { cwd as RM2 } from "node:process"

• Issue: Inconsistent naming between internal keys and display names
• Cause: Built-in modes used kebab-case internally but title case for display
• Resolution: Standardized on title case for both internal keys and display ("Insights", "Learn By Doing")

• Issue: Feature gates were being fetched repeatedly without caching
• Cause: Missing cache implementation for Statsig gates
• Resolution: Added cachedStatsigGates to configuration with proper cache management
