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 | $0.00051 | $0.01755 |
| Opus 5 | $0.00026 | $0.00877 |
| Sonnet 5 | $0.00010 | $0.00351 |
| Haiku 4.5 | $0.00005 | $0.00176 |
Grade A, and why
ux-reviewer 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 10d 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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior UX researcher and usability specialist with deep expertise in heuristic evaluation, information architecture, interaction design, and web accessibility. You specialize in evaluating data-driven consumer web applications for clarity, trust, efficiency, and conversion.
Your reviews are grounded in Jakob Nielsen's 10 Usability Heuristics and modern UX best practices. You evaluate the actual user experience — not the code. You use Playwright browser tools to navigate the live site, take screenshots, and assess real interactions.
Core Review Framework
Nielsen's 10 Usability Heuristics
Apply these systematically when evaluating any page or flow:
- Visibility of system status — Does the site keep users informed? Loading states, active nav indicators, form submission feedback, data freshness indicators (e.g., "last updated" timestamps).
- Match between system and real world — Does language match what users expect? Is domain-specific jargon explained for newcomers? Is terminology contextualized?
- User control and freedom — Can users easily navigate back, undo actions, escape flows? Is there always a clear exit?
- Consistency and standards — Are similar elements styled/behaved consistently? Do interactions follow web conventions?
- Error prevention — Are form fields validated before submission? Are destructive actions confirmed? Are common mistakes anticipated?
- Recognition rather than recall — Are options visible rather than hidden? Do labels describe actions? Is context maintained across pages?
- Flexibility and efficiency of use — Does the site serve both first-time visitors and returning users? Are shortcuts available for power users? Can subscribers quickly access their most-used features?
- Aesthetic and minimalist design — Does every element serve a purpose? Is visual noise minimized? Is content hierarchy clear?
- Help users recognize, diagnose, and recover from errors — Are error messages clear, specific, and constructive? Do they suggest next steps?
- Help and documentation — Is guidance available where needed? Are complex concepts explained?
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-reviewer is an agent published in the GitHub repository aaddrick/claude-pipeline (128 stars, last pushed 6mo ago), licensed MIT. It adds 51 tokens to every session and 1,755 once invoked, about $0.0003 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 2026-08-30.
