qa-only

A report-only quality check for a web application, testing it as a user would and recording the results. Quality assurance, or QA, means checking that software behaves as expected.

In plain words
What is it for?
Testing clicks, forms, error states, accessibility, changed user flows, and saved data, then producing a health score and structured bug report.
Why use it?
It identifies bugs and usability problems without changing the application. The report includes evidence and reproduction steps so developers can investigate the findings.

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

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.

/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.

BitFun Team Mode Dispatch

When this skill is invoked by BitFun Team Mode, this skill supplies the report-only QA methodology. Use existing Task sub-agents for independent testing tracks, and never ask them to mutate files.

  • Do not assume a QA Reporter sub-agent exists. Choose only from the Task tool's available agents.
  • Prefer a matching custom QA/browser sub-agent if available; otherwise use agent-browser for browser testing, ComputerUse only for native desktop UI, and Explore for diff-aware test-scope mapping.
  • Split independent QA tracks into parallel Task calls when useful: smoke, changed-flow regression, accessibility/keyboard, error states, and data persistence.
  • Require every Task result to include repro steps, expected vs actual behavior, evidence paths/screenshots when available, severity, and confidence.
  • The main Team orchestrator consolidates duplicates and decides what blocks Ship.

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 .bitfun/team/qa-reports/baseline.json
Output dir .bitfun/team/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

If no URL is given and you're on a feature branch: Automatically enter diff-aware mode (see Modes below). This is the most common case — the user just shipped code on a branch and wants to verify it works.

Browser/desktop QA tooling: Use agent-browser for browser QA and BitFun ComputerUse only for native desktop surfaces it cannot reach. Save QA artifacts under .bitfun/team/qa-reports/.

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 GCWing/BitFun (1,871 stars, last pushed yesterday), licensed MIT. It adds 111 tokens to every session and 4,429 once invoked, about $0.0006 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 2026-08-30.
