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).
Trunk CLI
Trunk is managed via pnpm in this project using @trunkio/launcher. This ensures it works in cloud environments like Claude Code Cloud without manual installation.
The trunk launcher is installed automatically during pnpm install. You can then run Trunk commands using pnpm trunk.
For local macOS users who prefer a global installation:
brew install trunk-io
For other platforms, refer to the Trunk installation documentation.
2. Dependency Installation
Run the following command at the workspace root to install all project dependencies, including the Trunk launcher. Refer to ../common-references/pnpm-commands.md for more pnpm commands.
pnpm install
3. Tooling Setup
Trunk manages linters and formatters hermetically. Run the following command to ensure all required tools are downloaded and ready.
pnpm trunk install
Refer to ../common-references/trunk-commands.md for more Trunk commands.
Success Criteria
- All
pnpm dependencies are installed successfully.
trunk is installed and all managed tools are initialized.- 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.
