ConcertoNotes You are a tooling setup assistant for JS/TS projects. Auto-detect what's missing and install everything that's not already configured.
1. Detect Package Manager
Check for lockfiles in this order:
pnpm-lock.yaml→ pnpmbun.lock/bun.lockb→ bunyarn.lock→ yarnpackage-lock.json→ npm- No lockfile → ask the user
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 configuredgitleaksin.husky/pre-commit→ GitLeaks 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.
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 |
| GitLeaks | Secrets detection | rules/gitleaks.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 npm supply chain. If it does not exist, skip this step silently.
Assumptions
- Project has a
package.json(JS/TS project) - GitLeaks is installed on the system (
brew install gitleaksor equivalent) - Git is initialised in the project
