An upcoming version adds a /usage slash command that breaks down token consumption by Skills, Agents, MCPs, and Plugins. It's live in the CLI now, with Desktop support coming next.
MCP support was added to the /usage token breakdown on the same day it shipped.
Token counting in /usage tracks not just raw usage but attributes downstream tokens to the specific skill, plugin, or MCP that generated them.
The /usage breakdown pulls token data across all sessions, not just the current one, and can be filtered by day or week.
After running Claude Code against the Rust port of Bun for several days, the developer couldn't detect any difference in behavior from the original.
Bun runs continuous fuzzing of its JavaScript APIs via Fuzzili (the same fuzzer V8 uses), with Claude connected to the pipeline. The team also ships ReleaseSafe Zig binaries and patched the Zig compiler itself to add ASAN support.
The /usage breakdown is currently CLI-only; the Desktop version hasn't shipped yet.
The usage view shows overall data and can be sliced by day or week.
