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 | $0.00140 | $0.02463 |
| Opus 5 | $0.00070 | $0.01231 |
| Sonnet 5 | $0.00028 | $0.00493 |
| Haiku 4.5 | $0.00014 | $0.00246 |
Grade A, and why
frontend-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 12d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
frontend-design (dev-time)
A contributor workflow for editing AI Atelie's own chrome — the parts of the host app a user sees regardless of what they're designing inside the canvas. Dev-time only; does not load into adapter sessions spawned by the editor.
If you're editing the canvas frame, the chat sidebar, the toolbar, the projects screen, the settings dialog, or any CSS module under web/src/, this skill applies. If you're editing a SKILL.md under skills/<name>/ that governs user-generated designs, this skill does NOT apply — that's the product skill, a different surface.
Read the atelier first
atelier/ is AI Atelie's canonical craft rulebook. Tokens in web/src/index.css decide what the brand looks like; the atelier files decide how a competent designer uses them.
The frontmatter craft.requires declares which sections this skill depends on. Pull these into context before touching chrome — they are the floor, not aspiration:
| Atelier file | What it covers | When you need it |
|---|---|---|
| atelier/typography.md | Type scale, line height, ALL CAPS tracking floor (≥0.06em), font pairing, three-weight system, line length | Any text on screen |
| atelier/color.md | Palette structure (70-90% neutrals / 5-10% brand / 0-5% semantic / <1% effect), ≤2 visible --brand uses per screen, ink scale by job, contrast minimums, semantic naming |
Any styled surface |
| atelier/anti-ai-slop.md | The 7 P0 cardinal sins (lint-enforced): no Tailwind indigo, no two-stop trust gradients, no emoji-as-icons, no hardcoded display fonts, no rounded-card-with-left-border, no invented metrics, no filler copy. Plus soft tells and a chrome-PR checklist | Every chrome PR |
| atelier/state-coverage.md | Empty / loading / error states for any data-fetching surface | Anything that lists, fetches, or paginates |
| atelier/animation-discipline.md | Motion tokens, prefers-reduced-motion, when motion earns its place |
Anything that animates |
| atelier/accessibility-baseline.md | Contrast, keyboard, focus rings, ARIA on chrome | Any interactive control |
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.
