Install or upgrade MegaLinter on a repository. Use when the user wants to add MegaLinter.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MegaLinter setup Install or upgrade MegaLinter on the current repository. **Always use `npx mega-linter-runner` to scaffold or upgrade the configuration — never write `.mega-linter.yml` or CI workflow files from scratch.** Only refine the generated files afterwards. **Custom flavor repositories**: if — and only if — the user explicitly asks to create or maintain a **custom MegaLinter flavor** (their own image with just the linters they need, published from a dedicated `megalinter-custom-flavor-*` repository), this is a different job from the install flow below: load `custom-flavor.md` from this skill's directory and follow it instead. Everything else on this page targets a project that *consumes* MegaLinter. ## 1. Analyze the repository Gather what you need to answer the installer's options: - **Flavor**: detect the main technology and pick a [flavor](https://megalinter.io/flavors/) (`python`, `javascript`, `java`, `go`, `php`, `ruby`, `rust`, `salesforce`, `swift`, `terraform`, `dotnet`, `dotnetweb`, `c_cpp`, `documentation`, `formatters`, `security`, ...). Mixed or unclear → `all`. …

How to install
mdr add ulises-jeremias/agent-toolkit/megalinter-setup@sha256:ebca08e8b4ed69e7The line at the top of this page pins the label git:20261016.f2102cf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
