design-review

design-review is a skill for Claude Code, Codex from fusengine/agents. It costs 29 tokens per session (3,025 once invoked), scanned A, original, MIT.

A final quality gate for a design deliverable, combining rule-based checks with a bounded visual review.

In plain words
What is it for?
Use it to review completed web, web-app, iOS, Android, or animated designs against their visual rules, accessibility needs, themes, and rendered appearance.
Why use it?
It identifies blocking, major, minor, and polish issues before a design is reported as complete.

Token cost

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.

Security

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 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Findings are tagged P0-P3 (Blocking / Major / Minor / Polish) and reported individually — there is NO aggregate score, health score, or letter grade, ever; an aggregated number invites self-grading theater.

The visual review is a bounded loop, maximum 2 fix cycles: the loop exits PASS only once the register-applicable positive floors are actually met, and a plateau (cycle 2 repeating cycle 1's finding) stops immediately even at cycle 1 of 2.

Before any "done" claim, a mandatory in-loop challenger gate judges the deliverable blind — fresh-context, off a rendered PNG only, never fed this procedure's own reasoning. A Block from the challenger must be resolved or owner-accepted before "done" is reported.

Design Review — Final Quality Gate

When

After design-motion (web/webapp) or directly after the mockup (design-ios/ design-android). The last step before reporting any design deliverable done — never skipped, never reported as passed if it wasn't actually run (references/review-procedure.md Failure Handling).

Input

  • The complete rendered artifact: components/mockup with animations (if any) and interactive states.
  • design-system.md as the audit baseline (tokens, forbidden fonts, contrast floors).
  • The Je reproduis line written by design-web/design-webapp — three declared elements, two tagged [corpus: {reference}/{tokens section}] (measured procedure, the craft) and one tagged [sector: {url} — register] (register signal only; [sector: none — register from brief] is valid, an empty slot is not). A missing or untagged line is a blocking Part 1 finding — the binary verdict has no input without it.
  • The corpus pages opened (Gate 0 artefact 3): at least two {reference}-recode/index.html, named. The [corpus: …] tags prove the corpus was read, never that it was seen — and a page sourced from markdown alone clears every mechanical check and reads dead. Absent ⇒ blocking Part 1 finding.
  • The on-screen inventory (Gate 0 artefact 4): what each section physically carries, plus the screen-holding-floor verdict. Blocking when VISUAL_DENSITY ≤ 3 or DESIGN_VARIANCE ≥ 6; reported otherwise.
  • Any declared premium pattern(s); the signature element (design-method Step 2) instead gets a Signature Dominance verdict.
  • The plan's two structural picks — hero treatment (design-method/references/macrostructure-bank.md) and body sequence (design-method/references/body-sequence-bank.md). A plan naming neither is itself a detector signal (anti-slop entry 15). brand register; a product deliverable carries neither.
  • The register (brand/product, from design-method Gate 0) — an input, never inferred mid-review: check 14's floors, Part 2 item 8's floors and the Lookalike Test (item 8b) all branch on it.

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 fusengine/agents (25 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 3,025 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 2026-09-03.
