description	Profiles ccusage performance. Use when debugging slow Rust CLI commands, TypeScript package scripts, launchers, benchmarks, packaging hot paths, or branch-vs-main speed changes.

ccusage Profile

Use this skill for ccusage performance work. The production CLI is Rust-first, but TypeScript launcher, benchmark, and packaging scripts still need Bun profiling when those paths are in scope.

Rust

Read references/rust.md for native CLI profiling, branch-vs-main worktree setup, hyperfine validation, JSON parity checks, and PR performance workflow reproduction.

TypeScript And Bun

Read references/typescript.md for Bun profiler commands, package script profiling, TypeScript launcher/benchmark setup, profile reading, local Bun docs, and ccusage-specific performance lessons.
