impeccable-posttooluse-hook-enables-zero-token-design-scanning

Impeccable’s 3,590-line JS detection engine runs deterministically via npx impeccable detect --json <file> with zero LLM tokens consumed. Wiring it as a PostToolUse hook on Write/Edit for .html/.css/.tsx/.jsx/.svelte/.astro files gives automated violation surfacing at near-zero cost. The 25 rules cover 13 AI-slop tells (glassmorphism, gradient text, pill badges, bounce easing, card-in-card nesting, etc.) and 12 general quality checks.
