lint-and-validate
Automatic code quality checks and validation across Node.js, TypeScript, and Python projects.
Works with
What it does
Runs linting, type checking, and security audits with ecosystem-specific tools (ESLint/TypeScript for Node.js, Ruff/MyPy/Bandit for Python)
Enforces a mandatory quality loop: write code, run audit, analyze report, fix issues, and repeat until all checks pass
Includes helper scripts for unified lint checking and type coverage analysis across project paths
Blocks code submission until all v
Installation Guide
How to use lint-and-validate on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your machine
- ›Node.js 16+ with npm — verify with
node --version - ›Active project directory where you want to add
lint-and-validate
Run the install command
Execute the skills CLI command in your project's root directory to begin installation:
Fetches lint-and-validate from sickn33/antigravity-awesome-skills and configures it for Cursor.
Select Cursor when prompted
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate lint-and-validate. Access via /lint-and-validate in your agent's command palette.
Security Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.
Documentation
Lint and Validate Skill
MANDATORY: Run appropriate validation tools after EVERY code change. Do not finish a task until the code is error-free.
Procedures by Ecosystem
Node.js / TypeScript
- Lint/Fix:
npm run lintornpx eslint "path" --fix - Types:
npx tsc --noEmit - Security:
npm audit --audit-level=high
Python
- Linter (Ruff):
ruff check "path" --fix(Fast & Modern) - Security (Bandit):
bandit -r "path" -ll - Types (MyPy):
mypy "path"
The Quality Loop
- Write/Edit Code
- Run Audit:
npm run lint && npx tsc --noEmit - Analyze Report: Check the "FINAL AUDIT REPORT" section.
- Fix & Repeat: Submitting code with "FINAL AUDIT" failures is NOT allowed.
Error Handling
- If
lintfails: Fix the style or syntax issues immediately. - If
tscfails: Correct type mismatches before proceeding. - If no tool is configured: Check the project root for
.eslintrc,tsconfig.json,pyproject.tomland suggest creating one.
Strict Rule: No code should be committed or reported as "done" without passing these checks.
