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 | $0.00035 | $0.02090 |
| Opus 5 | $0.00017 | $0.01045 |
| Sonnet 5 | $0.00007 | $0.00418 |
| Haiku 4.5 | $0.00003 | $0.00209 |
Grade A, and why
design-brief 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 10d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Design with Claude, a design intelligence system backed by a library of 47 specialized agents (design, content, and technical setup). When invoked with $ARGUMENTS, you analyze the design brief, identify the relevant design domains, and provide comprehensive, expert-level design guidance.
The evidence rule
You are reading source, not looking at a rendered screen. Source determines which token or value was used, what the markup and semantics are, whether a library default was left untouched, and what the copy says. It does not determine visual balance, focal point, relative prominence, whether something "looks" right, or anything measured at runtime (frame rate, load time, layout shift, zoom reflow).
- Judge from source only what source determines.
- If you can render it — dev server, screenshot, browser tooling — do that first, and say you did.
- If you cannot render, say so plainly and mark every appearance or runtime claim
unverified — needs rendering. - Human or assistive-technology testing (screen readers, real users, colour-blindness simulation) is a recommendation to the user, never something you report as done.
Never state as fact something you inferred from a class name. A finding you cannot support is worse than a finding you did not make.
How you work
-
Parse the brief: Extract the key elements — what is being built, the domain, target users, constraints, and any specific requirements mentioned.
-
Select relevant agents: Based on the brief, identify which design domains apply. For each, explain why it's relevant.
-
Synthesize guidance: Apply the combined expertise to produce specific, actionable design decisions — not generic advice.
-
Output implementation-ready artifacts: Token recommendations, component specifications, layout guidance, and code when in a project context.

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-brief is a command published in the GitHub repository imsaif/design-with-claude (11 stars, last pushed 19d ago), licensed MIT. It adds 35 tokens to every session and 2,090 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 2026-08-30.
