qa-only

qa-only is a skill for Claude Code, Codex from timurgaleev/vibestack. It costs 34 tokens per session (4,122 once invoked), scanned C, original, MIT.

A report-only quality-assurance skill for systematically testing a web application. It produces a health score, screenshots, and steps for reproducing problems, but does not change the code.

In plain words
What is it for?
Use it to test a web app and create a structured report with screenshots and reproduction steps without applying fixes.
Why use it?
It separates finding and documenting defects from fixing them, which is useful when you need an independent bug report.

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 C, and why

qa-only scanned grade C with 2 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 yesterday.

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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

12. **Never refuse to use the browser.** When the user invokes /qa or /qa-only, they are requesting browser-based testing. Never suggest evals, unit tests, or other alternatives as a substitute. Even if the diff appears

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

If `BROWSE_NOT_AVAILABLE`: skip all `$B` commands and use text-only fallbacks (curl, open, direct HTTP checks).

How it starts

The opening of the file, as written. The whole thing — 414 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to invoke

Use when asked to "just report bugs", "qa report only", or "test but don't fix". For the full test-fix-verify loop, use /qa instead.

Proactively suggest when the user wants a bug report without any code changes.

Voice triggers (speech-to-text aliases): "bug report", "just check for bugs".

/qa-only: Report-Only QA Testing

You are a QA engineer. Test web applications like a real user — click everything, fill every form, check every state. Produce a structured report with evidence. NEVER fix anything.

Every instruction that follows describes how to observe and record. Nothing below authorises an edit, a commit, or a "quick fix while I'm here" — a bug you fix is a bug the report can no longer prove was there, and the user chose this skill precisely because they want the diagnosis without the diff. When a fix looks obvious, that is not an invitation: record the observation and move on.

Setup

Parse the user's request for these parameters:

Parameter Default Override example
Target URL (auto-detect or required) https://myapp.com, http://localhost:3000
Mode full --quick, --regression .vibestack/qa-reports/baseline.json
Output dir .vibestack/qa-reports/ Output to /tmp/qa
Scope Full app (or diff-scoped) Focus on the billing page
Auth None Sign in to [email protected], Import cookies from cookies.json

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.

qa-only is a skill published in the GitHub repository timurgaleev/vibestack (6 stars, last pushed 3d ago), licensed MIT. It adds 34 tokens to every session and 4,122 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (tells the agent never to refuse, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
