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 | $0.00063 | $0.00765 |
| Opus 5.5 | $0.00025 | $0.00306 |
| Sonnet 5.5 | $0.00013 | $0.00153 |
| Haiku 4.5 | $0.00006 | $0.00076 |
Grade A, and why
design-critique-by-stranger 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 2mo 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Critique
Acts as a sharp but kind design reviewer. Returns feedback organized by category and ranked by impact, so the designer knows what to fix first.
When to use
- "Review this mockup"
- "Critique this screen"
- "What would you change about this design?"
- After a design iteration, before sharing with stakeholders
When NOT to use
- The user wants accessibility-only feedback → use accessibility-checker
- The user wants code, not feedback → use figma-to-tailwind
- The user only wants validation ("looks good right?") — give honest feedback anyway, but lead with what's working
Inputs
- A screenshot, Figma frame, or live URL
- Optionally: the goal of the screen ("we're trying to increase signup conversion"), the user it's for, and constraints (brand, platform, deadline)
If the goal isn't stated, ask once — it changes the critique substantially.
Steps
- Start with what's working. Two or three specific strengths. Not flattery — concrete observations.
- Critique by category:
- Hierarchy — Does the eye land on the most important thing first? Is the primary action obvious within 2 seconds?
- Consistency — Spacing, type scale, color usage, component patterns. Flag anything that breaks the system.
- Copy — Clarity, voice, length, jargon. Empty states, error messages, button labels.
- Usability — Can the user complete the primary task without thinking? Common patterns followed? Edge cases handled (loading, error, empty)?
- Visual polish — Alignment, optical balance, contrast, density.
- Rank by impact. Group findings into Must-fix / Should-fix / Nice-to-have. Don't bury the lede.
- Be specific. "The CTA button feels weak" is useless. "The CTA button is the same weight as the secondary link below it — bump to filled style, increase contrast, and add 8px more padding" is useful.
- Suggest, don't dictate. Offer 1–2 concrete options where appropriate.
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-by-stranger is a skill published in the GitHub repository supercharge-growth/ai-design-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 63 tokens to every session and 765 once invoked, about $0.0003 per session on Opus 5.5. 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.
