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 | $0.00124 | $0.03315 |
| Opus 5.5 | $0.00050 | $0.01326 |
| Sonnet 5.5 | $0.00025 | $0.00663 |
| Haiku 4.5 | $0.00012 | $0.00331 |
Grade A, and why
design-critique scanned grade A with 1 finding 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.

design-critique
Judges a built thing against what you said you wanted. One question, asked seriously: does this match the stated intent, and where it doesn't, how does it actually read?
Design feedback from a model fails in two directions and this skill is shaped against both. It flatters — every finding hedged into a suggestion, every section opening with what's working — or it produces a checklist of generic improvements that would apply equally to any interface ever built. Both are useless. What's useful is the thing a good design critic does: name how the thing reads to someone encountering it, then say what to do about it.
The hard gate in Step 1 is this skill's expression of ADR 0021, which closes by naming this skill directly: it "may only review against a written brief, because reviewing against nothing is exactly the generation this decision forbids." Critique is a check, and a check needs something to check against.
Three rules govern this skill:
- Diagnosis before prescription. Every finding must first name how the thing reads — in the form "reads as X rather than Y" — before any fix is proposed. No diagnosis, no finding. This is not a stylistic preference: a fix without a diagnosis is a guess, and it's how critique turns into an arbitrary list of changes. Five chips floating in an empty card "read as browser tabs rather than an iteration canvas." That sentence is the entire value of a critique; the fix follows from it in a way it never does from "consider adjusting the spacing".
- Delete is a verdict, and it's first in the list. Most model critique only ever adds — another affordance, another label, another explanatory line. In practice the most common good design move is removal: the redundant CTA, the feature card promising something that doesn't ship yet, the caption explaining what the UI already shows, the greyed-out button that's never enabled.
- Against intent, not against taste. With no written intent this becomes your aesthetic preferences delivered with authority. That's why the gate in Step 1 is hard rather than advisory.
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 vidhunnan/agentic-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 124 tokens to every session and 3,315 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
