Major improvements to mom's logging and cost reporting: Centralized Logging System: - Add src/log.ts with type-safe logging functions - Colored console output (green=user, yellow=mom, dim=details) - Consistent format: [HH:MM:SS] [context] message - Replace scattered console.log/error calls throughout codebase Usage Tracking & Cost Reporting: - Track tokens (input, output, cache read/write) and costs per run - Display summary at end of each run in console and Slack thread - Example: 💰 Usage: 12,543 in + 847 out (5,234 cache read) = $0.0234 Prompt Caching Optimization: - Move recent messages from system prompt to user message - System prompt now mostly static (only changes with memory files) - Enables effective use of Anthropic's prompt caching - Significantly reduces costs on subsequent requests Model & Cost Improvements: - Switch from Claude Opus 4.5 to Sonnet 4.5 (~40% cost reduction) - Fix Claude Opus 4.5 cache pricing in ai package (was 3x too expensive) - Add manual override in generate-models.ts until upstream fix merges - Submitted PR to models.dev: https://github.com/sst/models.dev/pull/439 UI/UX Improvements: - Extract actual text from tool results instead of JSON wrapper - Cleaner Slack thread formatting with duration and labels - Tool args formatting shows paths with offset:limit notation - Add chalk for colored terminal output Dependencies: - Add chalk package for terminal colors
