What is ux-interview?

A simulated user who tests a website or product by completing realistic tasks and describing their reactions aloud. It produces a report of usability problems, positive moments, and suggested improvements.

Use it to review navigation, sign-up, purchasing, or other user journeys from a chosen user’s perspective.

It reveals where real users may become confused or blocked, including issues automated tests may not identify.

Token cost

What it costs to keep this loaded

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	$0.00147	$0.04398
Opus 5	$0.00073	$0.02199
Sonnet 5	$0.00029	$0.00880
Haiku 4.5	$0.00015	$0.00440

Security

Grade A, and why

ux-interview 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 — 368 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UX Interview

Play a real user in an interview-style test of a web product. Narrate think-aloud reactions live as you click, scroll, and try to accomplish realistic goals — then deliver a structured report with severity-ranked findings, delight moments, and prioritized recommendations.

This skill is not an automated test runner (see /ui-test for that). It is a qualitative user-perspective audit. Findings are based on judgement, not assertions.

Preferences

On startup, use the Read tool to load ~/.claude/skills/ux-interview/preferences.md. If missing, treat as first-run (see First-time detection).

Defaults when no preferences exist:

output-root: ./ux-interviews/ (cwd-relative when in a project; falls back to ~/.claude/skills/ux-interview/runs/ otherwise)
default-depth: standard (quick ≈ 5–7 min walkthrough / standard ≈ 12–18 min / deep ≈ 25 min+ with multiple flows)
narration-style: expressive (expressive — feels like a real user / neutral — observational / terse — short notes only)
persona-mode: auto-suggest (auto-suggest with override / always-ask / fixed-default)
severity-floor: minor (nitpick / minor / moderate / major — anything at-or-above is reported)
capture-mode: friction-only (friction-only / per-section / never) — when GIFs/screenshots are taken
viewport: 1440x900 — also accepts a list (e.g. 375x812,1440x900) to test responsive
confirm-plan: always (always / never) — confirm the test plan before opening the browser
auto-open-report: true

Also load ~/.claude/skills/ux-interview/feedback-journal.md if present — surface the latest 5 Signal: lines to bias defaults (e.g. if the user repeatedly downgraded "minor copy issues", raise the severity floor pre-selection).

Context

On startup, use Bash to detect: today's date+time (date +%Y-%m-%d-%H%M), the current working directory (pwd), and whether the configured output-root exists. Do NOT call any browser tool yet — that happens in Step 4.

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.
