+# Hooks Guidance for Cursor
+
+Cursor does not have a native hooks system like Claude Code's PreToolUse/PostToolUse/Stop hooks. However, you can achieve similar automation through:
+
+## Formatting on Save
+
+Configure your editor settings to run formatters on save:
+- **TypeScript/JavaScript**: Prettier, ESLint with `--fix`
+- **Python**: Black, Ruff
+- **Go**: gofmt, goimports
+
+## Linting Integration
+
+Use Cursor's built-in linter support:
+- ESLint for TypeScript/JavaScript
+- Ruff/Flake8 for Python
+- golangci-lint for Go
+
+## Pre-Commit Hooks
+
+Use git pre-commit hooks (via tools like `husky` or `pre-commit`) for:
+- Running formatters before commit
+- Checking for console.log/print statements
+- Running type checks
+- Validating no hardcoded secrets
+
+## CI/CD Checks
+
+For checks that ran as Stop hooks in Claude Code:
+- Add them to your CI/CD pipeline instead
+- GitHub Actions, GitLab CI, etc.
