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 | $0.00084 | $0.01275 |
| Opus 5 | $0.00042 | $0.00638 |
| Sonnet 5 | $0.00017 | $0.00255 |
| Haiku 4.5 | $0.00008 | $0.00128 |
Grade A, and why
ux-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 12d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UX Audit
Run a structured usability audit and produce a scored, severity-ranked report. This skill is the qualitative-heuristics counterpart to two siblings: ux-metrics (quantitative behavioral data — task success, time-on-task, conversion, drop-off) and accessibility-audit (WCAG conformance — contrast, keyboard, screen readers, semantics). Keep the division of labor clear: this skill judges whether the design is usable and well-structured for a sighted user completing tasks; it does not measure traffic and it does not certify accessibility. A full /ux-audit engagement combines usability findings (this skill) with an accessibility pass (accessibility-audit) so nothing falls between the cracks.
When to use
Trigger on requests like: "audit this UX", "usability review", "heuristic evaluation", "review this flow", "review this screen", "what's wrong with this UI", "is this usable", "evaluate this onboarding". Use it whether the goal is a quick critique or a formal scored report — always produce the scored output, scaled to the input.
Inputs
Work from whatever is available, in rough order of richness:
- Screenshots / mockups — evaluate visible structure, hierarchy, copy, affordances. Note that hidden states (loading, error, hover) cannot be judged and must be flagged as assumptions.
- A live page or URL — the strongest input; walk real tasks, trigger real states, count real steps.
- A description — evaluate the described flow and intent; ask for screenshots or a link if findings would be speculative.
- Source code — read component markup, routing, and state to infer the rendered experience and locate issues precisely (file and component names sharpen recommendations).
When the input is thin, state what could and could not be evaluated rather than inventing findings.
Method
Evaluate across these dimensions. Read references/nielsen-heuristics.md before scoring — it defines each heuristic, what to look for, and the severity scale.
What ships with it
2 files 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.

ux-audit is a skill published in the GitHub repository TimboGP/timbogp-marketplace (3 stars, last pushed 2mo ago), licensed MIT. It adds 84 tokens to every session and 1,275 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.
