These pages describe the official Dagger modules. They are the standard library of tools that give a workspace useful work to do: test code, run a test runner, lint and format source, or validate Helm charts.
Reach for a module when you want a real tool that runs the same way locally, in CI, and in Dagger Cloud. Most expose checks, generators, or repair workflows, so the work stays consistent everywhere it runs.
Add any module to your project with dagger module install:
dagger module install dagger.io/go
Each page explains what the module is for, which checks or generators to reach for first, the settings that tune it, and how it fits into your project.
