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 | $0.00077 | $0.02367 |
| Opus 5 | $0.00039 | $0.01184 |
| Sonnet 5 | $0.00015 | $0.00473 |
| Haiku 4.5 | $0.00008 | $0.00237 |
Grade A, and why
ux-dark-patterns-audit 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 8d 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.

Dark Patterns Audit Skill
How this skill behaves (read first)
This is an evaluative skill — it reviews existing work, auto-runs, and is built to be called as a validation step by generative skills, especially ones touching conversion, pricing, sign-up, subscription, or cancellation (pricing, login-signup, checkout-payment, onboarding, offboarding). It's the systematic version of the ethics guardrail those skills carry inline.
It owns intent to deceive/manipulate. Deliberate deferrals so it doesn't duplicate:
- Honest usability problems (a confusing-but-not-deliberate layout, unclear label) → the heuristics audit. A UX mistake is not a dark pattern.
- Visual clutter / overdesign → the aesthetics audit.
- Accessibility → the accessibility audit.
The line is intent: this audit asks whether the design exploits the gap between what users think they're doing and what the product actually does.
Scope discipline. When invoked directly (the user named this audit), review only this concern — don't pull in sibling audits. It runs alongside other lenses only when an orchestrator (ux-design-review) or a generative skill calls it under docs/orchestration-policy.md, where it sits in Tier A — always-relevant, auto-runs. Explicit scope always wins.
What this skill changes vs. default behavior
By default, manipulation only gets flagged when it's blatant, with no framework, no severity, and a tendency to either miss subtle patterns (preselection, forced continuity, manufactured FOMO, bad defaults) or over-accuse honest mistakes. This skill forces:
- A systematic sweep of the named pattern catalog — not just the obvious offenders.
- Intent classification — Dark vs. Grey vs. honest Mistake — so findings are fair, not alarmist.
- A concrete, honest-design fix for each.
- Decision tests (the Newspaper Test, the intent-gap question) that surface the subtle cases.
The core lens: intent and the dark / grey / mistake spectrum
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.

ux-dark-patterns-audit is a skill published in the GitHub repository Uxcel-Lab/product-skills (10 stars, last pushed 2mo ago), licensed MIT. It adds 77 tokens to every session and 2,367 once invoked, about $0.0004 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.
