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 | $0.00018 | $0.00955 |
| Opus 5.5 | $0.00007 | $0.00382 |
| Sonnet 5 | $0.00004 | $0.00191 |
| Haiku 4.5 | $0.00002 | $0.00096 |
Grade A, and why
ui-lint scanned grade A with 0 findings 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 4d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Lint (Quick Check)
When to Use
Use this skill when you need quick automated lint — detects common design system violations in seconds.
When NOT to use
- For deeper review of design judgment (composition, hierarchy, rhythm) → use
/ss-review - For accessibility specifically → use
/ss-a11y - For Nielsen UX heuristics → use
/ss-audit - For applying refactors — this only flags violations; use
/ss-reviewto fix
Target: $ARGUMENTS
What This Does
Fast, grep-based scan for common design violations. Runs in seconds (unlike /ss-review which is a deep manual audit). Run this after every file change.
Checks
1. Hardcoded Colors
Search for hex colors in className strings that should be semantic tokens:
grep -n '#[0-9a-fA-F]\{3,8\}' [file] | grep -v 'theme.css\|tokens\|\.json'
Violation: text-[#3C3C3C], bg-[#721FE5]
Fix: text-text-primary, bg-brand
2. Raw Pixel Values in Tailwind
grep -n 'p-\[.*px\]\|m-\[.*px\]\|gap-\[.*px\]' [file]
Violation: p-[24px], gap-[12px]
Fix: p-6, gap-3
3. Old Width/Height Syntax
grep -n 'w-[0-9] h-[0-9]\|w-\[.*\] h-\[' [file]
Violation: w-4 h-4
Fix: size-4
4. Physical Properties (LTR-only)
grep -n ' ml-\| mr-\| pl-\| pr-' [file]
Violation: ml-2, mr-4
Fix: ms-2, me-4
5. Forbidden Colors
grep -n 'text-black\|bg-black\|#000000\|#000"' [file]
Violation: Any pure black Fix: Use skin's text-primary token
6. Missing data-slot
grep -n 'function [A-Z]' [file] # find components
grep -n 'data-slot' [file] # check if present
Violation: Component without data-slot
Fix: Add data-slot="component-name"
7. Font Size CSS Variables (CRITICAL — Tailwind v4 conflict)
grep -n 'text-\[var(--' [file]
grep -n '\-\-text-.*px\|--fs-.*px' [file]
Violation: text-[var(--text-sm)] or --text-sm: 13px in theme.css
Fix: Use explicit text-[13px]. CSS variable font sizes conflict with Tailwind v4's --text-* namespace — Tailwind reads them as color, not font-size.
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.

ui-lint is a skill published in the GitHub repository skillmds/skillmd (1 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 955 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-19.
