QA Test

Verify implemented features in a real browser. Exercise each acceptance criterion, verify via snapshots, report results.

Context-efficient design: browser testing runs in a sub-agent so snapshot/interaction data stays out of the main thread. Main thread only sees compact pass/fail summaries.

Sub-agent rule: Always use sub-agents for browser interaction and pre-flight exploration — these are broad, multi-step tasks that generate significant context. Fan out pre-flight and browser testing as separate sub-agents when they're independent. Handle directly only when verifying a single, specific element or reading one file for criteria.

Process

1. Pre-flight (sub-agent) — gather criteria, resolve URL, check environment
2. Interactive setup — human steers browser for hard-to-automate steps (login, drag, etc.)
3. Browser testing (sub-agent) — exercises all criteria in isolated context
4. Report results — main thread receives compact summary only
5. Handle failures — retry failed criteria after manual intervention if needed

1. Pre-flight Sub-agent

Launch an Explore sub-agent before any browser interaction to gather all context in parallel.
