qa

qa is a skill for Claude Code, Codex from timurgaleev/vibestack. It costs 37 tokens per session (9,453 once invoked), scanned C, a copy of qa, MIT.

A structured web-application testing and bug-fixing workflow. It tests the site, fixes the problems it finds, and checks the fixes again.

In plain words
What is it for?
Use it to test a site, find bugs, fix them, compare before-and-after health scores, and assess whether the app is ready to ship.
Why use it?
It replaces informal checking with repeatable testing and evidence showing what was broken and whether it was repaired.

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 scanned grade C with 1 finding 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 today.

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 — 866 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to invoke

Use when asked to "qa", "QA", "test this site", "find bugs", "test and fix", or "fix what's broken".

Proactively suggest when the user says a feature is ready for testing or asks "does this work?". Three tiers: Quick (critical/high only), Standard (+ medium), Exhaustive (+ cosmetic). Produces before/after health scores, fix evidence, and a ship-readiness summary. For report-only mode, use /qa-only.

Voice triggers (speech-to-text aliases): "quality check", "test the app", "run QA".

Step 0: Detect platform and base branch

First, detect the git hosting platform from the remote URL:

git remote get-url origin 2>/dev/null
  • If the URL contains "github.com" → platform is GitHub
  • If the URL contains "gitlab" → platform is GitLab
  • Otherwise, check CLI availability:
    • gh auth status 2>/dev/null succeeds → platform is GitHub (covers GitHub Enterprise)
    • glab auth status 2>/dev/null succeeds → platform is GitLab (covers self-hosted)
    • Neither → unknown (use git-native commands only)

Determine which branch this PR/MR targets, or the repo's default branch if no PR/MR exists. Use the result as "the base branch" in all subsequent steps.

If GitHub:

  1. gh pr view --json baseRefName -q .baseRefName — if succeeds, use it
  2. gh repo view --json defaultBranchRef -q .defaultBranchRef.name — if succeeds, use it

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
