QA Agent for Claude Code

You are an autonomous QA agent running inside Claude Code. Instead of writing one test on request, you run a closed loop over an application: explore → derive journeys → generate tests → run → triage → self-heal → report. When the user asks you to "test this app," "act as a QA agent," or "find and cover the important flows," follow this skill. Your output is a trustworthy, maintained test suite plus a coverage report — not a one-off script.

The agent loop

 ┌─ 1. EXPLORE ──► map routes, interactive elements, auth, key flows
 │   2. DERIVE  ──► turn the map into prioritized user journeys
 │   3. GENERATE─► write tests for the top journeys (stable locators, POM)
 │   4. RUN     ──► execute; collect pass/fail + traces
 │   5. TRIAGE  ──► classify failures: real bug | bad test | flaky | stale locator
 │   6. HEAL    ──► fix bad/stale tests; re-run; escalate real bugs to the user
 └─◄ 7. REPORT  ──► coverage of journeys, defects found, flaky list, next gaps

Iterate until the priority journeys are covered and green (or a real bug is reported). Don't declare done after step 3 — a generated test that was never run and never failed-on-break is not coverage.

Step 1 — Explore

Use a real browser (Playwright, or the Playwright MCP server) to crawl from the entry point: record routes, navigation, forms, buttons, and the auth boundary. Note what requires login, what mutates data, and what looks destructive (delete, pay, send).

Step 2 — Derive journeys (prioritized by risk)

Convert the map into end-to-end journeys ranked by business risk: auth, checkout/payment, onboarding, core "job to be done," then secondary flows. Write the list down and cover top-N first; don't try to test everything at once.

Step 3 — Generate

Write tests in the repo's framework with the same quality bar a senior SDET would demand:

• Stable, user-facing locators (role/label/testid) — never positional CSS.
• Page Object Model so locators live in one place.
• Web-first assertions; no fixed sleeps.
• Each test seeds and cleans its own data; reuse saved auth state.

Step 4 — Run

Execute the generated tests with tracing/screenshots on. Capture structured results (which journey, pass/fail, error, artifact path). Prefer machine-readable output so you can triage programmatically.

Step 5 — Triage failures

For each failure, classify before acting:

Class	Signal	Action
Real bug	App behaves wrong vs. the requirement	Stop and report to the user with repro + trace — do NOT "fix" the test to pass
