winget install --id=rhysd.actionlint -e Static checker for GitHub Actions workflow files
ActionLint is a static checker designed to analyze GitHub Actions workflow files for errors, security issues, and best practices. It helps identify potential problems in workflow configurations before they cause runtime failures or security vulnerabilities.
Key Features:
- Syntax Validation: Ensures that workflow files adhere to the correct syntax by checking keys and structure against GitHub's requirements.
- Type Checking: Performs strong type checks on expressions (e.g.,
${{ }}) to detect issues like invalid property access, type mismatches, or incorrect usage of variables. - Action Usage Verification: Validates inputs, outputs, and secrets used in actions to ensure they align with the action's specifications.
- Reusable Workflow Checks: Examines reusable workflows for correct input/output definitions and secret usage.
- Security Analysis: Detects potential security risks such as script injection from untrusted sources or hard-coded credentials.
- Integration Support: Includes integrations like shellcheck and pyflakes to analyze scripts in workflow steps, ensuring they are safe and syntactically correct.
Audience & Benefit: Ideal for developers, DevOps engineers, and CI/CD pipeline maintainers who work with GitHub Actions. By identifying issues early, ActionLint helps reduce runtime errors, improve workflow reliability, enhance security practices, and streamline the development of CI/CD pipelines. It can be installed via winget or other package managers to integrate seamlessly into your workflow validation process.
