ccusage Profile

Use this skill for ccusage performance work. The production CLI is Rust-first, but the TypeScript launcher and Nushell benchmark/package scripts still need focused 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 Scripts

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