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 | $0.00020 | $0.01875 |
| Opus 5 | $0.00010 | $0.00937 |
| Sonnet 5 | $0.00004 | $0.00375 |
| Haiku 4.5 | $0.00002 | $0.00187 |
Grade A, and why
design-review 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 11d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Review Skill
Core Pack — Always Active
This is a core skill. Apply it on ALL visual and frontend work, no exceptions. You do not need permission or a specific trigger to use this.
Visual foundation contract
Read ../agentic-design-system/contracts/visual-foundation.v2.json before build or review.
Confirmed never rules block presentation.
- Never put a border on only one edge of a rounded rectangle. A complete perimeter remains valid.
- Never recreate that one-edge treatment with a zero-blur or inset shadow.
- Never force uppercase styling. Authored interface copy uses sentence case or title case, with a narrow exception for literal external identifiers that would become inaccurate if changed.
- Never use em dashes in interface copy.
- Never use static or animated status dots. Status remains readable without color; add an icon only when it materially improves scanning or comprehension.
- Use a real icon when a control has an icon equivalent. Preserve one coherent project family; otherwise use licensed Nucleo or one open family, never a mix.
- Utility work starts with the product font, a system sans, or another conventional general-purpose family. Expressive typography requires an eligible surface or an explicit outcome.
- Custom letter spacing and line height come from a declared type role, not decorative improvisation.
- Avoid colons in interface copy when a normal phrase works. Literal time, links, code, protocols, structured data, and verbatim external data remain valid.
- Use whitespace and grouping before adding dividers. Divider density stays an independent review judgment rather than a brittle automatic gate.
When to Use
- Before presenting ANY visual or UX work.
- Treat this as a quality gate, not optional polish.
- Sub-agents doing design/frontend work MUST run this before announcing completion.
Pre-Work: Read Before Building
1. Read the project's guidelines
- Read
guidelines.mdor equivalent design system doc first if it exists. - Follow the project's existing components, tokens, and patterns before inventing anything.
- If no formal guidelines exist, inspect the existing product and match its logic.

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-review is a skill published in the GitHub repository aa-on-ai/agentic-design-system (5 stars, last pushed 21d ago), licensed MIT. It adds 20 tokens to every session and 1,875 once invoked, about $0.0001 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 2026-08-31.
