Set Up Your MCP Dev Stack in Claude Code: GitHub, Postgres, Playwright, Filesystem

Production Agent System Prompt Template
A fill-in-the-blanks system prompt for tool-using agents — role, goals, tool policy, autonomy limits, escalation rules, output contract and self-checks — following Anthropic's published guidance on building effective agents.
Exploratory QA Agent with Playwright MCP
Turns Claude Code + Playwright MCP into a methodical QA tester: it explores your app like a user, reproduces bugs with exact steps, and writes Playwright regression tests for what it finds.
