# Playwright E2E AI Skill Guide (Gemini)

## Operational Capabilities & Agent Directives

1. **Trace waterfall**: Identify last successful action before timeout.
2. **Strict mode**: Screenshot showing multiple matching elements → locator too broad.
3. **Worker collisions**: Failures only on sharded CI → shared DB user conflict.

## Agent Operational Directive

> **MANDATORY**: Recommend locator narrowing and worker-scoped data before increasing retries.
