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 | $0.00105 | $0.02325 |
| Opus 5.5 | $0.00042 | $0.00930 |
| Sonnet 5.5 | $0.00021 | $0.00465 |
| Haiku 4.5 | $0.00011 | $0.00232 |
Grade A, and why
design-critique 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 1mo 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.
This is a copy
91% identical to critique — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Critique Skill · 5 维度专家评审
Produce a single-file HTML "design review report" that scores any artifact across 5 dimensions and proposes actionable fixes. Inspired by the huashu-design expert-critique flow.
When to use
- After the agent (or user) generates an artifact (deck / prototype / landing page) and the user asks "what's wrong with this?" or "review this"
- As a self-check loop the agent can run on its own output before emitting it
- For comparing two variants of the same design
What you produce
A single self-contained <artifact type="text/html"> review report
including:
- Header — what artifact was reviewed, date, reviewer ("OD · Critique skill"), 1-line verdict
- Radar chart (inline SVG, no library) showing the 5 scores
- Five dimension cards, each with:
- Score 0–10 (with band: 0–4 Broken · 5–6 Functional · 7–8 Strong · 9–10 Exceptional)
- 1-paragraph evidence (cite specific elements / files / lines)
- One Keep / Fix / Quick-win bullet
- Combined action lists at the bottom:
- Keep — what's working, don't touch
- Fix — P0 / P1 issues that are visually expensive
- Quick wins — 5–15 minute tweaks with disproportionate impact
The 5 dimensions
Each dimension is independent — a deck can be 9/10 on Innovation but 4/10 on Hierarchy and the report should say so plainly. Don't average away interesting failures.
1. Philosophy consistency · 哲学一致性
Does the artifact pick a clear direction and stick to it through every micro-decision (chrome / kicker / spacing / accent)?
Evidence to look for:
- Is there one declared design direction (e.g. Monocle / WIRED / Kinfolk) or is it three styles in a trench coat?
- Does the chrome / kicker vocabulary stay in one register, or does page 3 say "Vol.04 · Spring" and page 7 say "BUT WAIT 🔥"?
- Are accent / serif / mono used by the same rule throughout?
0–4 Three styles fighting each other. 5–6 One direction but half the elements drift. 7–8 Coherent, occasional drift on edge pages. 9–10 Every element argues for the same thesis.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-critique is a skill published in the GitHub repository the-sid-dani/second-brain-os (3 stars, last pushed 7d ago), licensed MIT. It adds 105 tokens to every session and 2,325 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to critique, differing in 33 lines, and is treated as a copy.

scholar-nerd-style
Apply a scholarly 'nerd' visual style to single-file handwritten HTML document sites: publication-list look, restrained typography, no frameworks. Use when building or reviewing a lab site, a publications page or any new page that should match this house style. Triggers: /scholar-nerd-style, /nerd, nerd style, scholar…
visual-asset-design
A guide for turning character, scene, and prop ideas into prompts for generating consistent reference images. It covers layouts, camera views, visual identity, and continuity across image variations.
ui-mockup
Create UI mockups at three fidelity levels — ASCII wireframes for quick iteration, standalone HTML mockups for delivery with requirements, and live prototypes for interaction testing.
oma-design
Define or review a visual system, DESIGN.md, or redesign direction. Use for typography, layout, color, motion, and interaction design decisions.
conversion-review
Review a landing page or form to find why visitors do not sign up or buy: unclear message, friction, missing proof, weak call to action. Looks at the real page on desktop and phone and ranks the fixes.
frontend-design
Give a web page or app its own look instead of a generic AI-made one: choose colors, type and layout on purpose before building, then critique the result. Use when building a new interface or reshaping an existing one.
