Replace black/pylint/super-linter with ruff #2819
Conversation
Ruff is 10-100x faster than traditional Python linters and can replace multiple tools with a single, unified configuration. ## Deleted (replaced by ruff) - .github/workflows/black.yml - .github/workflows/black_auto.yml - .github/workflows/pylint.yml - .github/workflows/linter.yml (super-linter) - .github/workflows/matchers/*.json ## Added - .github/workflows/ruff.yml - Fast Python linting + YAML validation - .pre-commit-config.yaml - Git hooks for automated checks - .yamllint - YAML linting configuration - pyproject.toml - Ruff configuration (replaces black/pylint settings) ## Benefits - Single tool instead of black + pylint + flake8 + isort - 10-100x faster than traditional linters - Pre-commit hooks catch issues before CI - Native pyproject.toml configuration 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

To fix the problem, we need to explicitly set the permissions block in the workflow. For this workflow, the only activities are linting the code and yaml files—no steps involve writing results back to the repository, interacting with issues, or creating PRs. Therefore, the minimal permission required is contents: read. The permissions: key can be added either at the workflow root (affecting all jobs) or within a specific job (affecting only that job). Since there is only one job (lint), either is acceptable; best practice is at the workflow root for simplicity. To implement the change, add a block directly below the workflow name: on line 2:
permissions:
contents: readNo new imports or custom methods are needed for this change.
