// Profiles Bun TypeScript and JavaScript package scripts. Use for launcher, benchmark, or packaging hot paths; use ccusage-rust-profile for native CLI performance.
Guides ccusage Rust tests. Use when adding or fixing cargo tests, CLI snapshots, Claude model pricing, LiteLLM compatibility, or Rust fixture-backed parser and loader tests.
Guides ccusage TypeScript package and tooling work. Use when editing apps/ccusage .ts/.js files, Vitest tests, Bun scripts, package launchers, schema tooling, or benchmark scripts.
Guides ccusage Rust implementation work. Use when editing rust/crates, native packaging, parser/module layout, pricing embedding, or Rust/TypeScript parity.
Creates atomic Conventional Commits. Use when committing code changes, splitting hunks into revertable units, or writing detailed commit messages.
Runs the full PR lifecycle. Use when creating a branch, committing, pushing, opening a PR, requesting AI review, and driving CI and review to completion.
Guides t-wada Red-Green-Refactor TDD. Use when implementing features, fixing bugs, or refactoring logic with strict test-first development.

Use this skill for TypeScript package scripts. The production CLI is Rust-first,
so native command performance work should use the ccusage-rust-profile skill
instead.
Read references/profile-workflow.md before profiling. It contains the Bun
profiler commands, ccusage branch-vs-main setup, hyperfine validation,
profile-reading checklist, Bun reference lookup, and lessons from past ccusage
performance work.
