Which package managers are supported?

It supports a wide range of managers including npm, yarn, pnpm, bun, poetry, uv, pip, cargo, go modules, bundler, maven, and gradle.

Does this work with local development?

Yes, it works locally by default, but you can use the --remote-only flag to restrict the hook's execution to web-based sessions to save time on your local machine.

Can I customize the generated script?

Absolutely. The skill creates a standard shell script at scripts/claude-session-start.sh that you can manually edit to include custom setup logic or specific environment requirements.

What does the SessionStart hook actually do?

It runs a shell script every time you start or resume a Claude Code session to ensure your dependencies are installed, environment variables are set, and your project is ready for development.

Will this overwrite my existing Claude settings?

No, the skill intelligently merges the new hook configuration into your existing .claude/settings.json file and prompts you for action if a SessionStart hook is already defined.

배포 및 DevOps

Automates environment setup, dependency installation, and health checks for Claude Code development sessions.

This skill streamlines the onboarding process for repositories in Claude Code by generating a custom SessionStart hook. It automatically detects your project's technology stack—including Node.js, Python, Rust, Go, Ruby, and Java—to install dependencies using frozen lockfiles, configure environment variables, and verify that tests and linters are passing before you start coding. This ensures a consistent and functional development environment across both local and remote web sessions, significantly reducing manual configuration time.
