Guides ccusage monorepo development. Use when editing packages, docs, shared configuration, bundled CLI packaging, dependencies, exports, or validation commands.
Guides ccusage Rust and Vitest tests. Use when adding or fixing cargo tests, CLI snapshots, Claude model pricing, LiteLLM compatibility, Vitest tests, or fixture-backed tests.
Guides ccusage TypeScript and JavaScript work. Use before reading or editing .ts, .tsx, .js, or .jsx files, including package launchers, Vitest tests, Bun scripts, schemas, mocks, and typed fixtures.
Guides t-wada Red-Green-Refactor TDD. Use when implementing features, fixing bugs, or refactoring logic with strict test-first development.
Creates atomic Conventional Commits. Use when committing code changes, splitting hunks into revertable units, or writing detailed commit messages.
Checks local bun-types documentation before using or changing Bun runtime APIs such as Bun.$, files, spawning, argv, stdout, stderr, and string width.

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