Claude Code adds usage command, cache warnings

Anthropic's CLI coding tool now provides a detailed `/usage` breakdown and proactive UI warnings to help developers avoid expensive prompt cache misses. The update targets the high cost of resuming stale sessions by nudging users to optimize context before usage spikes.

// ANALYSIS

Claude Code's transparency update addresses the "cache miss tax," where losing the prefix cache can make a single prompt 10–20x more expensive.

–The new `/usage` command visualizes consumption drivers like sub-agent activity and context size
–Proactive warnings now alert users before they resume long-running sessions that have timed out (typically >5 minutes)
–Actionable optimization tips encourage the use of `/compact` and `/clear` to maintain a lean, cache-friendly context
–This shift from "black box" token usage to explicit cost-management tools is a critical step for making autonomous agents viable for enterprise production
–Increased visibility into the 5-minute TTL window helps developers time their turns to maximize cache hit rates
