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 | $0.00024 | $0.01799 |
| Opus 5 | $0.00012 | $0.00899 |
| Sonnet 5 | $0.00005 | $0.00360 |
| Haiku 4.5 | $0.00002 | $0.00180 |
Grade A, and why
Form UX Optimizer 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.

Form UX Optimizer
What this skill does
This skill reviews the code and design of web forms to identify usability and accessibility issues. It checks for poor field ordering, confusing labels, missing or unhelpful error messages, incorrect input types, broken keyboard navigation, and accessibility violations. The output is a prioritized list of specific improvements with code examples for each fix.
Use this before shipping a registration, checkout, contact, or any data-entry form — especially when your form has a high abandonment rate or you're getting support requests about users not knowing what to enter.
How to use
Claude Code / Cline
Copy this file to .agents/skills/form-ux-optimizer/SKILL.md in your project root.
Then ask:
- "Use the Form UX Optimizer skill to review our checkout form in
CheckoutForm.tsx." - "Review this registration form for UX and accessibility issues using the Form UX Optimizer skill."
Provide the form component code and, if available, any validation logic.
Cursor
Add the instructions below to your .cursorrules or paste them into the Cursor AI pane. Provide the form code to review.
Codex
Paste the form HTML/JSX and validation code. Ask Codex to follow the instructions below.
The Prompt / Instructions for the Agent
When asked to review a form for UX, follow this checklist systematically:
Category 1 — Field design and labeling
Labels
- Every input must have a visible
<label>element (not just placeholder text) - Labels must be associated with inputs via
for/htmlForor wrapping - Placeholder text must not be used as a substitute for labels — it disappears on input and has poor contrast
- Required fields must be clearly marked (e.g., asterisk with a legend explaining it means required)
Field order
- Fields should follow a logical, natural sequence (name before email, shipping before billing)
- Related fields should be grouped visually and in DOM order
- The most important or most-filled field should come first, not last
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.
