Setup Development Environment
This skill automates the process of setting up the development environment to ensure all tools and dependencies are correctly installed and configured.
Workflow Checklist
Detailed Instructions
1. Environment Validation
Node.js Version
Read the .node-version file in the workspace root. Ensure the current Node.js environment matches this version. If there's a mismatch, inform the user to switch Node versions (e.g., using nvm or fnm).
2. Dependency Installation
Run the following command at the workspace root to install all project dependencies. This brings the Trunk launcher into node_modules/.bin so pnpm scripts can run trunk without a global install. Refer to ../common-references/pnpm-commands.md for more pnpm commands.
pnpm install
3. Verify Trunk
Confirm the launcher is available:
pnpm exec trunk --version
If this fails, dependencies may be incomplete—re-run pnpm install at the repo root.
If you need a global trunk on your PATH (optional), see the Trunk installation guide. On macOS, Homebrew (brew install trunk-io) is one option.
4. Tooling Setup
Trunk manages linters and formatters hermetically. Run the following command to ensure all required tools are downloaded and ready. Refer to ../common-references/trunk-commands.md (including Trunk in this repository (pnpm)) for more Trunk commands.
pnpm exec trunk install
Success Criteria
- All
pnpm dependencies are installed successfully.
pnpm exec trunk --version succeeds.- Managed Trunk tools are initialized if you ran
pnpm exec trunk install.
- The Node.js version matches the requirement in
.node-version.
Post-Setup Verification
To ensure the environment is fully operational:
- Invoke Verifier: Run the
verifier subagent (../../agents/verifier.md). This confirms that the freshly installed dependencies allow for a successful build, pass lint checks, and satisfy all unit tests.
- Handle Failure: If the
verifier fails, follow its reporting to resolve environment-specific issues.
