qaBrowser-based QA verification. An agent skill from SethGammon/Citadel.
QA is an agent skill from SethGammon/Citadel. Browser-based QA verification. Launches a real browser, navigates the app, clicks buttons, fills forms, and tests user flows. Works as a standalone skill or as a phase end condition in campaigns. Requires Playwright (optional dependency, graceful skip if not installed).
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `__benchmarks__/no-playwright.md` and `__benchmarks__/no-server.md`).
It sits in Testing & QA, covering Browser testing and UX design. It works with Playwright and npm. The repository describes itself as: The operating layer for Claude Code + OpenAI Codex: persistent project memory, intent routing, safety hooks, cost telemetry, and parallel agent fleets. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit e41ff1d. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
npxnpmnodeFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npx and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
QA loads about 2.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 887 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
NEVER read from `.env` (protected by the hook). Use test accounts only.- Access .env files (uses .env.example or test credentials from campaign)Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/qa/SKILL.md (or your agent's skills folder). This skill also uses 2 other files; get the full folder from GitHub./qa requires Playwright. It's an optional dependency.
If Playwright is installed: full browser QA works. If Playwright is NOT installed: the skill offers to install it, or falls back to /live-preview (screenshot-only verification).
Detection:
npx playwright --version 2>/dev/nullInstallation (if user agrees):
npm install -D playwright
npx playwright install chromiumOnly installs Chromium (smallest download, ~150MB). Not Firefox or WebKit unless the user asks for cross-browser testing.
/do setup integration: During setup, if the project is a web app (has React, Next.js, Vue, Svelte, or HTML files), offer to install Playwright: "I see this is a web project. Want to enable browser QA testing? This installs Playwright (~150MB) for interaction testing. (y/n)"
If they say no, /qa falls back to /live-preview. No pressure.
Before testing, understand what to test:
If no PRD or campaign exists, ask: "What should I test? Give me 1-3 user flows."
Before testing, the app needs to be running:
npm run dev or equivalent, in backgroundTrack whether the agent started the server. If so, kill it on completion.
For each flow identified in Step 1, write and run a Playwright script:
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch({ headless: true });
const page = await browser.newPage();
// Navigate
await page.goto('http://localhost:3000');
// Verify page loaded
const title = await page.title();
// Test interactions
await page.click('button[data-testid="add-todo"]');
await page.fill('input[name="title"]', 'Test todo');
await page.click('button[type="submit"]');
// Verify result
const todoText = await page.textContent('.todo-item:last-child');
// Screenshot for evidence
await page.screenshot({ path: '.planning/screenshots/qa-flow-1.png' });
await browser.close();
})();For each test:
Write results to .planning/qa-report-{date}.md:
# QA Report: {App Name or Feature}
> Date: {ISO date}
> Flows tested: {N}
> Passed: {N}
> Failed: {N}
> Screenshots: .planning/screenshots/qa-*.png
## Results
### Flow 1: {description}
- Steps: {what was done}
- Expected: {what should happen}
- Actual: {what did happen}
- Result: PASS / FAIL
- Screenshot: {path}
- Notes: {any observations}
### Flow 2: ...When running as a phase end condition:
The campaign file can specify QA conditions:
| 3 | qa_verify | /qa passes for: add todo, complete todo, delete todo |/qa reads the condition, runs those specific flows, and reports pass/fail. The phase is complete only if all specified flows pass.
For apps with authentication:
Test credentials should come from .env.example or the campaign file.
NEVER read from .env (protected by the hook). Use test accounts only.
If Playwright isn't installed and the user declines installation:
Playwright not installed and user declines: Fall back to /live-preview. Mark all interaction tests as SKIPPED in the report. Visual-only verification still runs.
Dev server won't start: Report the startup error and stop. Do not attempt to test a server that isn't running. Suggest the user fix the startup error first.
No routes or pages discoverable: Ask the user for 1-3 flows to test. Do not guess at routes.
No UI (API-only project): Report "No UI detected — /qa requires a browser-accessible interface. Use typecheck and unit tests for API verification." Then stop gracefully.
If .planning/screenshots/ does not exist: Create it before saving screenshots. If .planning/ doesn't exist, save screenshots to a qa-screenshots/ directory in the project root and note the path in the report.
After saving screenshots, videos, rendered PDFs, or QA reports in Codex, register each durable artifact so the Codex app/browser workflow can find it later:
node scripts/codex-app-artifacts.js record --workflow qa --kind screenshot --path ".planning/screenshots/qa-flow-1.png" --status passThe manifest lives at .planning/artifacts/codex-app-evidence.jsonl.
Before reporting QA as complete in Codex, verify the manifest points at real files:
node scripts/codex-app-artifacts.js verify --require-artifactsDisclosure: May start a dev server; saves screenshots and report to .planning/. States server ownership before starting.
Reversibility: amber — creates report and screenshots; dev server stopped only if this skill started it. Delete generated files to undo.
Trust gates: Any. Familiar (5+) to run against external/production URLs.
---HANDOFF---

Browser-based QA verification. An agent skill from SethGammon/Citadel. QA is an agent skill from SethGammon/Citadel. Browser-based QA verification.
QA fits situations like: tasks that involve Browser testing; tasks that involve UX design.
Run `npx skills add SethGammon/Citadel --skill qa -a claude-code`. Or copy the skill folder (skills/qa in SethGammon/Citadel) into .claude/skills/qa in your project. Claude Code loads it when a task matches its description.
Run `npx skills add SethGammon/Citadel --skill qa -a codex`. Or copy the skill folder (skills/qa in SethGammon/Citadel) into .agents/skills/qa in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add SethGammon/Citadel --skill qa -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/qa, .gemini/skills/qa, .github/skills/qa and .opencode/skills/qa in your project.
Going by SKILL.md and its folder, QA needs the command-line tools its instructions call (npx, npm and node). Our summary lists: Node.js.
SKILL.md contains no URLs. Its commands use npx and npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
QA is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with QA: Playwright (Kiln-AI/Kiln, 5.2k stars), UI Preview (tingly-dev/tingly-box, 351 stars), Run One Spec (LiberatedPixelCup/Universal-LPC-Spritesheet-Character-Generator, 1.8k stars) and UI Visual Debugging (NangoHQ/nango, 13k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
