ccusage

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

Guides ccusage monorepo development. Use when editing packages, docs, shared configuration, bundled CLI packaging, dependencies, exports, or validation commands.

Creates atomic Conventional Commits. Use when committing code changes, splitting hunks into revertable units, or writing detailed commit messages.

Guides ccusage Nushell scripts. Use when adding, editing, formatting, or validating .nu scripts, Nix shebangs, GitHub Actions script calls, or just recipes that invoke Nushell.

Guides t-wada Red-Green-Refactor TDD. Use when implementing features, fixing bugs, or refactoring logic with strict test-first development.

Guides ccusage Rust and Node tests. Use when adding or fixing cargo tests, Node test files, CLI snapshots, Claude model pricing, LiteLLM compatibility, or fixture-backed tests.

Guides ccusage TypeScript and JavaScript work. Use before reading or editing .ts, .tsx, .js, or .jsx files, including package launchers, Node tests, schemas, mocks, and typed fixtures.

Guides Rust binary size reduction for ccusage. Use when changing release profiles, dependency features, native packaging size, or investigating Rust executable bloat.

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 repo-local skill creation and updates. Use when adding or editing .agents/skills, SKILL.md frontmatter, references, scripts, or skill routing.

Guides ccusage agent source formats. Use when checking agent log locations, raw record structure, token mappings, model names, precomputed costs, or source-specific CLI behavior.

Routes ccusage documentation impact work. Use when code or behavior changes affect README files, docs guides, VitePress navigation, screenshots, schema docs, or user-facing commands/options.

Diagnoses and fixes failing GitHub Actions checks with gh. Use when CI fails on a pull request and needs logs, focused fixes, and validation.

Guides ccusage Rust implementation work. Use when editing rust/crates, native packaging, parser/module layout, pricing embedding, or Rust/TypeScript parity.

Guides ccusage structural code searches with ast-grep. Use when finding Rust or TypeScript syntax patterns, validating migrations, or writing AST-based search commands.

Detect duplicate Rust code using AST-based similarity analysis. Use when working with .rs files and looking for code duplication or refactoring opportunities.

Guides cmux terminal debugging. Use when validating CLI visual output, responsive tables, terminal geometry, long-running commands, or pane captures.
