Install

curl -fsSL https://han.guru/install.sh | bash
han plugin install --auto

This is third-party code. Review the repository files before installing.

What it does

Han installs a CLI that detects the project stack and picks plugins. When Claude Code finishes, hooks run linters, formatters, type checks and tests so the code is ready to merge. Plugins fall into categories: core, languages, frameworks, validation, tools, MCP integrations, engineering discipline agents and practices like TDD. Checks are cached and rerun only when related files change, and success metrics stay local.

Who it is for. For developers who want Claude Code to run quality checks on its own before handing work back.

Good fit when

  • You want linters and tests to run after every agent session
  • You want stack-matched plugins in one command
  • You need ready agents for security, accessibility or architecture

Not a fit when

  • Checks are already set up in your own Claude Code hooks
  • You do not use Claude Code or its hooks

Example request

Install Han and pick plugins for this project

Limitations

Claude Code is the main target; other agents rely on separate bridge plugins. Hooks run project tools, so sessions take longer to finish. Installs via a curl script or Homebrew; GitHub does not detect the license, the README states MIT.

How to disable. Remove plugins with han plugin uninstall <name>; han hook explain shows which hooks are configured.

Security check

  • Hooks execute project linters and tests
  • Installs via a script from the internet

README in short

The README promises a two-command start: install the CLI and auto-select plugins. It describes the loop: install, normal agent work, stop-hook validation and local metrics. It includes a plugin category table and CLI command reference, including an MCP server for running hooks. Full docs live at han.guru.

FAQ

Does any data leave my machine?

The README says metrics and confidence calibration stay on your machine.

Can I choose plugins manually?

Yes, han plugin search queries the marketplace and han plugin install <name> installs a specific plugin.
