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.

What it costs to keep this loaded
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 | $0.00130 | $0.02405 |
| Opus 5 | $0.00065 | $0.01203 |
| Sonnet 5 | $0.00026 | $0.00481 |
| Haiku 4.5 | $0.00013 | $0.00241 |
Grade A, and why
design-brand-system 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 8d 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 — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.

design-brand-system
Visual design system skill for brand-aligned web projects. Absorbed from the retired v2.x *-design-system capability (per the design-system absorption policy) at v1.0.0. Enforces hero-first chaining, WCAG 2.1 AA contrast, and structured design token output for downstream implementation.
Quick Reference
Entry Conditions
Before generating design output, verify:
.moai/project/brand/visual-identity.mdexists and contains no_TBD_markers.- Copy scope is defined (from
design-copywritingJSON output or inline brief). - Target framework is confirmed (from
.moai/config/sections/design.yamldefault_framework).
If visual-identity.md has unresolved _TBD_ markers, stop and request brand interview completion.
If the defined color palette conflicts with generated design tokens, execution halts and a conflict report is returned (see Error Handling below).
Figma Integration
Figma integration is disabled by default. Check .moai/config/sections/design.yaml:
figma:
enabled: false
If figma.enabled: true and a public Figma file URL is provided, extract design tokens from the Figma file. Otherwise use visual-identity.md as the sole source of truth.
Implementation Guide
Hero-First Chaining
The hero section establishes the visual tone for the entire site. All subsequent sections chain from it:
- Extract hero background color, typography, and spacing from
visual-identity.md. - Derive complementary section colors using the established contrast ratio rules.
- Apply consistent spacing scale across all sections (do not reset per section).
- Navigation and footer inherit hero's typographic scale.
Hero section requirements:
- CTA button is visible above the fold on mobile (375px viewport, 667px height).
- Headline contrast ratio against background: minimum 4.5:1 (WCAG AA).
- Hero image or background: never pure white (#FFFFFF) unless brand explicitly specifies.
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.

design-brand-system is a skill published in the GitHub repository modu-ai/moai-cowork (300 stars, last pushed 8d ago), licensed Apache-2.0. It adds 130 tokens to every session and 2,405 once invoked, about $0.0006 per session on Opus 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 2026-09-03.

instant-ui
Build a BenAI-branded HTML page in the neo-brutalist instant-ui design language (cream background, near-black ink, 3px hard borders, 6px zero-blur shadows, a blue/green/amber gradient stripe, system font plus SF Mono, weight-900 headings).

motion-system
Define the app's motion language before animating anything -- a small set of durations, easings, and named moves that every animation draws from, so the app feels designed instead of decorated. Use before writing the first animation in a project, or when existing motion feels scattered.
polish-pass
The de-AI pass -- audit a vibe-coded app for template smell in design and copy, then fix it with editorial layout, purposeful motion, and human-sounding words. Use after any build session, before anyone else sees it.
