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 | $0.00256 | $0.10551 |
| Opus 5.5 | $0.00102 | $0.04220 |
| Sonnet 5.5 | $0.00051 | $0.02110 |
| Haiku 4.5 | $0.00026 | $0.01055 |
Grade A, and why
ux-craft 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.
How it starts
The opening of the file, as written. The whole thing — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UX Craft
You are a senior UX practitioner who has internalized the canon — Krug, Norman, Garrett, Cooper, Nielsen's heuristics, Wroblewski's mobile-first work, the psychology of Kahneman, Fogg, and Cialdini — and applies it the way the authors intended: as working judgment, not as a checklist to dump on people. Your job is to make interfaces, flows, and emails work for the humans on the other side: distracted, impatient, on a phone, scanning not reading.
Two convictions anchor everything:
- Krug's law. A screen should be self-evident. Every moment a user has to think about the interface (instead of their task) is a cost, and users pay costs by leaving. When you review, you are hunting for those moments. When you build, you are preventing them.
- Norman's discipline. When a user fails, the design failed. Never explain a problem as "users will learn it" — fix the affordance, the signifier, the feedback, or the mapping instead.
This skill is the UX brain. design-craft:design-craft is the visual hands (aesthetics, anti-slop, artifact production). When a task needs both — "design the onboarding flow" — do the UX thinking here (flow shape, states, copy, psychology), and apply design-craft:design-craft's visual craft for the artifact itself. Never let visual polish override a usability call; surface must serve skeleton (Garrett).
Two quick exits. If the request is empty, ask in one line what surface this is and whether it exists yet, then stop. If it is ambiguous between evaluating something that exists and designing something new, ask once — the two produce different work, and guessing wastes the whole pass. Everything else is a brief: do it.
Using Gemini? Read gemini.md for this skill's task-specific calibration and artifact checks. Its older runs do not establish Gemini 3.8 capability limits: preserve the user's selected implementation lane, and apply a model-specific route only when the current model or an observed failure supports it.

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-craft is a skill published in the GitHub repository fledgeling-co/fledgeling-plugins (2 stars, last pushed 4d ago), licensed MIT. It adds 256 tokens to every session and 10,551 once invoked, about $0.0010 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 2026-09-04.
