Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.01360 |
| Opus 5 | $0.00014 | $0.00680 |
| Sonnet 5 | $0.00005 | $0.00272 |
| Haiku 4.5 | $0.00003 | $0.00136 |
Grade C, and why
lint-design-system scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

/lint-design-system
Scan changed files for design system violations. Detects hardcoded colors, raw spacing values, inline typography, and touch target issues.
Process
1. Detect Stack
Determine which stack to scan:
- If
*.dartfiles exist inlib/→ run Flutter checks - If
*.html,*.scss,*.tsfiles exist insrc/→ run Angular checks - If both → run both
2. Flutter Design Checks
Scan lib/**/*.dart (exclude *.g.dart, *.freezed.dart):
| Check | Pattern | Violation |
|---|---|---|
| Hardcoded colors | Color(0x...), Colors.xxx |
Use Theme.of(context).colorScheme tokens |
| Raw spacing | EdgeInsets.all(N), SizedBox(height: N) with numeric literals |
Use AppSpacing.xs/sm/md/lg/xl/xxl |
| Raw TextStyle | TextStyle(fontSize: N) |
Use Theme.of(context).textTheme |
| Small touch targets | SizedBox with width/height < 48 wrapping GestureDetector/InkWell |
Minimum 48x48dp for interactive elements |
Commands to run:
# Hardcoded colors
grep -rn "Color(0x\|Colors\." lib/ --include="*.dart" | grep -v ".g.dart" | grep -v ".freezed.dart" | grep -v "test/" | grep -v "// ignore-design"
# Raw spacing
grep -rn "EdgeInsets\.\(all\|symmetric\|only\)([0-9]" lib/ --include="*.dart" | grep -v ".g.dart" | grep -v ".freezed.dart" | grep -v "// ignore-design"
# Raw TextStyle
grep -rn "TextStyle(fontSize:" lib/ --include="*.dart" | grep -v ".g.dart" | grep -v ".freezed.dart" | grep -v "// ignore-design"
3. Angular Design Checks
Scan src/app/**/*.{html,scss,css,ts}:
| Check | Pattern | Violation |
|---|---|---|
| Hardcoded hex colors | bg-[#...], text-[#...], color: #... |
Use daisyUI semantic tokens (bg-primary, text-base-content) |
| Hardcoded rgb/hsl colors | rgb(...), rgba(...), hsl(...), hsla(...) |
Use daisyUI semantic tokens or CSS custom properties |
| Raw spacing utilities | mt-3, px-4, gap-2 (numeric) |
Use Tailwind's semantic scale or daisyUI component spacing |
| Raw typography | text-[14px], font-[...], font-size: N |
Use Tailwind typography scale (text-sm, text-lg) |
| Raw form inputs | <input> without formControl, bare <select> |
Use daisyUI form classes + reactive form bindings |
| Inline styles | style="..." in templates |
Use TailwindCSS utilities or SCSS |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lint-design-system is a command published in the GitHub repository kumaran-is/claude-code-onboarding (35 stars, last pushed 2mo ago), licensed MIT. It adds 27 tokens to every session and 1,360 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

The v2 flagship. Runs the 5-parallel-search Python engine across 11 data manifests (75+ styles, 170+ palettes, 65+ type pairs, 120+ components, 170+ industries, 110+ UX laws, 50+ motion presets, 120+ anti-patterns, 92 brand specs) and returns a complete recommended design system for your project — with always-on…
color-specialist
Use when colour is failing. Contrast below AA, a palette with no system behind it, dark mode that is only inverted light mode, or semantic colours that carry no meaning.
responsive-design-specialist
Use when a layout breaks between sizes. Arbitrary breakpoints, type that does not scale, images that blow out the grid, or a desktop design retrofitted onto mobile.
