meow:lint-and-validate

Automatic quality control — runs linting, type checking, and security scanning after every code change.

What This Skill Does

Enforces the quality loop: write code → run lint → run typecheck → fix errors → repeat until clean. Supports Node.js/TypeScript (npm run lint, npx tsc --noEmit) and Python (ruff check, mypy). No code is committed or reported as "done" without passing these checks.

Core Capabilities

• Node.js/TypeScript — npm run lint, npx tsc --noEmit, npm audit
• Python — ruff check --fix, bandit -r, mypy
• Mandatory — No code submitted without passing checks
• MeowKit scripts — Uses .claude/scripts/validate.py and security-scan.py

Usage

Auto-activates after every code modification. Also triggered by: "lint", "format", "check", "validate", "types", "static analysis".
