auto-test

auto-test is a skill for Claude Code, Codex from A7um/zero-review. It costs 25 tokens per session (1,164 once invoked), scanned A, original, MIT.

A simulated user-testing workflow that runs a built application through realistic goals and reports the experience.

In plain words
What is it for?
Use it after an application can run to test it through different user personas and produce structured feedback from their perspective.
Why use it?
It finds not only crashes but also confusion, delays, awkward flows, and missing features that technical checks may overlook.

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.

Security

Grade A, and why

auto-test 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 4d 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.

Auto-Test Skill

WHEN TO USE: You have a built, runnable artifact and need to exercise it from a user's perspective — discovering bugs, friction, and feature gaps through realistic usage.

Testing Philosophy

You are a user, not an engineer. Experience the software, don't analyze it.

Have a goal, not a checklist — Real users open software to accomplish something. You do the same. Your persona has goals — pursue them naturally, don't methodically sweep every feature.

Friction is signal — Confusion, slowness, unexpected behavior, and missing affordances are all findings. Not just crashes. A flow that "works" but takes 12 clicks when it should take 3 is a real problem.

Report what you experienced — Describe what happened from the user's perspective. "The page was blank for 5 seconds after I clicked Save" — not "the React hydration failed due to a missing Suspense boundary." You're a reporter, not a diagnostician.

Respect your persona's limits — A novice gives up when confused. A power user pushes through. An adversarial tester tries to break things. Your behavior must match the persona you adopted — don't be omniscient.

Stop when your goals are done — Don't hunt for edge cases beyond your persona's natural behavior. When your goals are attempted (achieved or abandoned), the session is over.

Capability Tiers

Not all testing modes are equally reliable. Check this table before starting — it determines what interaction toolkit to use and what confidence to assign to findings.

Capability Tier Model Requirement Notes
CLI tool testing Stable Any Text-in text-out, fully reliable
REST/GraphQL API testing Stable Any HTTP interaction, structured responses
Web app — DOM/accessibility tree Stable Any Playwright structured interaction
Web app — visual validation Experimental Vision-capable (GPT-4o+, Gemini Pro Vision+) Screenshot interpretation varies by model
Desktop GUI — Electron Experimental Vision-capable (GPT-5.4+, Claude with vision) Playwright Electron mode; reasonable but fragile
Desktop GUI — native (GTK/Qt) Experimental Strong vision + tool-use (GPT-5.4+) xdotool + AT-SPI; expect failures on complex flows
Realistic persona simulation Experimental Strong role-play (GPT-5.4+, Claude Opus+) Agent perceives as engineer; persona constraints help but authentic confusion is hard to simulate

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.

auto-test is a skill published in the GitHub repository A7um/zero-review (45 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 1,164 once invoked, about $0.0001 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.
