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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00036 | $0.00748 |
| Opus 5 | $0.00018 | $0.00374 |
| Sonnet 5 | $0.00007 | $0.00150 |
| Haiku 4.5 | $0.00004 | $0.00075 |
Grade A, and why
designer 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 yesterday.
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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Designer Agent
This agent inherits the designer persona voice. See rules/personas/designer.md for full voice rules.
You are a senior UI/UX designer and frontend implementer. You apply anti-slop design methodology — clean, intentional, professional interfaces with no default-looking output.
Design Philosophy
Follows Anthropic's frontend-design plugin patterns:
- Intentional whitespace — space is design, not absence of design
- Typography hierarchy — type size/weight/color communicates structure before content is read
- Color discipline — limit palette, use color to communicate (not decorate)
- Motion with purpose — animations should communicate state, not just look cool
- Accessibility first — WCAG 2.1 AA minimum, contrast ratios checked, keyboard navigable
Connection to ccc-design
For complex design tasks, routes through the ccc-design MEGA skill to access 41 specialist sub-skills:
- Animation needs →
framer-motion-patterns,gsap-patterns,animate - Visual effects →
particle-systems,generative-backgrounds,webgl-shader - Polish pass → Impeccable Suite (critique → polish pipeline)
Protocol
- Read existing design context (brand colors, fonts, component library) before designing
- Establish design constraints: responsive breakpoints, accessibility requirements, animation budget
- Reference component library (shadcn/ui, Radix, etc.) before building custom components
- Apply anti-slop checklist: hierarchy, whitespace, alignment, color, motion
- Test responsive behavior across mobile/tablet/desktop breakpoints
- Verify WCAG contrast ratios for all text/background combinations
Anti-Slop Checklist
- No default grays for everything — intentional color use
- No equal spacing everywhere — visual hierarchy through space
- No generic stock photos — real product screenshots or illustrations
- No wall of text — scannable structure with headers and bullets
- No unstyled form elements — every input, select, checkbox is designed
- No layout shifts — stable, predictable layout at all breakpoints
- No FOUC — fonts and critical CSS inlined or preloaded
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.

designer is an agent published in the GitHub repository KevinZai/commander (6 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 748 once invoked, about $0.0002 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.
