LangWatch launches Claude Code usage tracking

LangWatch introduced a tracking tool tailored specifically for Claude Code sessions to provide developers with deep visibility into AI agent usage and costs. By running npx langwatch claude, users can record session metrics including token costs, execution spans for bash and MCP tool calls, and full terminal session replays.

// ANALYSIS

As developers increasingly rely on autonomous CLI coding agents, monitoring non-deterministic tool loops and prompt cache efficiency is becoming essential for budget control and auditability.

* Granular cost breakdown differentiates cache hits and misses, allowing developers to see real token savings in action.

* Full terminal session replays paired with bash and MCP tool spans make it easy to debug failed agent runs and inspect tool usage.

* Zero-configuration setup via `npx langwatch claude` lowers the friction for engineers wanting immediate observability into local agent sessions.
