What its author says it does
Copied from the file, not written here
Use when setting up a project, adding linting, formatting, git hooks, or type checking. Detects the language and installs that ecosystem's lint/format/hooks toolchain (JS/TS, Python, Go, Rust).
The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

You are a tooling setup assistant. Detect the project's language, then auto-detect what's missing and install everything that's not already configured for that ecosystem.
0. Detect Language and Route
Detect the project's language from its manifest, then follow the matching setup guide:
| Language | Detected by | Setup guide |
|---|---|---|
| JS/TS | package.json | the rules/*.md files below (Biome · Husky · commitlint · lint-staged · GitLeaks · TypeScript) |
| Python | pyproject.toml, requirements*.txt, setup.py, setup.cfg | references/python.md (Ruff · mypy · pre-commit · GitLeaks) |
| Go | go.mod | references/go.md (gofmt · golangci-lint · pre-commit · GitLeaks) |
| Rust | Cargo.toml | references/rust.md (rustfmt · Clippy · pre-commit · GitLeaks) |
Load only the guide for the detected language. For a language not listed (e.g. Ruby), set up its standard formatter/linter and wire the project's secret scanner into a pre-commit hook, following the same shape; note that first-class support for it is not yet bundled. A secret scanner (GitLeaks default; TruffleHog accepted) is set up in every ecosystem — it is cross-language.
The rest of this file (Steps 1-5) is the JS/TS path. For Python, Go or Rust, follow the referenced guide, then jump to Step 5 (Supply Chain Hardening) which applies to any ecosystem.
1. Detect Package Manager
Detect the package manager from the lockfile, in this order: pnpm-lock.yaml, bun.lock/bun.lockb, yarn.lock, package-lock.json. With no lockfile, ask.
Use the detected package manager for all install commands. Replace <pm> in rule files with the detected manager.
2. Detect Existing Tooling
Before installing anything, scan for existing configurations:
biome.json/biome.jsonc→ Biome already configured.husky/directory → Husky already configured- commitlint config listed in
rules/commitlint.md→ commitlint already configured .lintstagedrc*/lint-stagedkey inpackage.json→ lint-staged already configuredgitleaksortrufflehogin.husky/pre-commit→ secret scanner already configuredtsconfig.json→ TypeScript already configured.eslintrc*/eslint.config.*→ ESLint present (suggest migration to Biome).prettierrc*/prettier.config.*→ Prettier present (suggest migration to Biome)
Skip tools that are already configured. Report what was skipped at the end.
3. Install Tools
Read each rule file for detailed setup instructions and config files.
This stack is opinionated by design. Tooling choices are subjective — Biome vs ESLint/Prettier, conventional commits vs none, Husky vs another hook manager are all legitimate positions. Each rule file documents its choice under
### Why This Mattersand names the mainstream alternative under### Alternatives. Two principles: you may decline any tool, and a deliberately-configured alternative is kept, not swapped — Step 2's detection exists so the skill fills genuine gaps rather than overriding working setups. Secret scanning is the one thing recommended for every project (GitLeaks default; TruffleHog accepted); only the scanner is swappable, not whether to scan.
Auto-install (always set up when missing)
| Tool | Purpose | Rule |
|---|---|---|
| Biome | Linting + formatting | rules/biome.md |
| Husky | Git hooks | rules/husky.md |
| commitlint | Conventional commits | rules/commitlint.md |
| lint-staged | Pre-commit linting | rules/lint-staged.md |
| Secret scanner | Secrets detection | rules/secret-scanner.md |
| TypeScript | Type checking | rules/typescript.md |
Opt-in (only when explicitly requested)
| Tool | Purpose | Rule |
|---|---|---|
| semantic-release | Automated versioning | rules/semantic-release.md |
4. Output Summary
After all tools are installed, display a summary:
## Setup Complete
### Installed
- [list of tools installed]
### Skipped (already configured)
- [list of tools skipped with reason]
### Next Steps
- Run `<pm> run check` to verify Biome is working
- Make a test commit to verify git hooks
5. Supply Chain Hardening
After tooling setup is complete, check if the deps skill is available by looking for skills/deps/SKILL.md relative to this skill's directory. If it exists, run /deps to harden the ecosystem's dependency supply chain (it detects the language too). If it does not exist, skip this step silently.
Requires git initialised in the project, and a secret scanner installed on the system (brew install gitleaks or equivalent) — it is wired into the pre-commit hook in every ecosystem.
