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 | $0.00062 | $0.03730 |
| Opus 5.5 | $0.00025 | $0.01492 |
| Sonnet 5.5 | $0.00012 | $0.00746 |
| Haiku 4.5 | $0.00006 | $0.00373 |
Grade A, and why
web-design 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 24d 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 — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
web-design
Guidance for producing web UI that looks deliberately designed, not auto-generated. The single failure mode this skill exists to prevent: shipping something a viewer can immediately tell an AI made. If it reads as the AI default — purple gradients, beige hero, three equal cards, em-dashes, Inter on slate-900 — it failed, regardless of how clean the code is.
Three ideas run through everything here:
- Taste is trained, not innate. Good design is a stack of small correct decisions, each defensible. There is no single magic move.
- Unseen details compound. The 75ms exit animation, the 1px focus ring offset, the tinted neutral instead of pure gray — individually invisible, collectively the difference between "fine" and "considered."
- Restraint beats expression by default. One accent, one type scale, one corner-radius scale, motion only where it earns its place. Reach for more only when the brief asks for it.
When to use this
Use it whenever you design or review web UI: a landing page, a dashboard, a component, a form, a marketing section. Use it before you call a screen "done." Don't treat it as always-on — it's a lens for visual/frontend work, not a tax on every code change.
Workflow
- Read the brief (below) — infer intent, write a one-line Design Read, set the dials.
- Apply the fundamentals — type, color, spacing, the interactive states. Pull depth from
references/as needed. - Avoid the anti-patterns —
references/anti-patterns.mdis the load-bearing don't-list. - Look at it in a browser — screenshot and eyeball. Do not ship on faith (see Iterate by eye).
- Run the pre-ship checklist (below) before declaring done.
The brief read
Before writing any CSS, infer from what you were asked:
- Page kind — product UI / dashboard / landing page / form / docs / editorial. This dominates every other choice (a dashboard and an Awwwards landing page want opposite densities).
- Audience & register — internal tool / consumer / enterprise / public-sector.
- Vibe words & references — anything the brief implies about feel ("calm", "punchy", "premium").
- Hard constraints — accessibility requirements, regulated/public-sector rules, brand assets. These override aesthetic preference, always.
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

web-design is a skill published in the GitHub repository DanielC000/loom (7 stars, last pushed yesterday), licensed MIT. It adds 62 tokens to every session and 3,730 once invoked, about $0.0002 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 2026-08-31.
