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 (python, javascript, java, go, php, ruby, rust, salesforce, swift, terraform, dotnet, dotnetweb, c_cpp, documentation, formatters, security, ...). Mixed or unclear → all.
• CI system: from existing config (.github/ → gitHubActions, .gitlab-ci.yml → gitLabCI, azure-pipelines.yml → azure, bitbucket-pipelines.yml → bitbucket, Jenkinsfile → jenkins, .drone.yml → droneCI) or the git remote host. None → other.
• Default branch: git remote show origin or the current repository default.

2. Install or upgrade

No MegaLinter configuration yet — run the installer non-interactively:
