A FastAPI + vanilla JS chat app fronting an Anthropic Claude agent for order status, returns, and policy questions. Architecture: - agent.py: system prompt, runtime reminder injection, output validation, agentic tool-use loop with prompt caching on the system prompt block - tools.py: four tools (lookup_order, check_return_eligibility, initiate_return, lookup_policy) with per-session SessionGuardState enforcing protocol ordering on the tool side - mock_data.py: orders, return policy, and FAQ entries used as the single source of truth by both the prompt and the tools - server.py: FastAPI app exposing /api/chat, /health, and the static UI - static/: vanilla HTML/CSS/JS chat UI, no build step - tests/: 30 tests covering tool-side enforcement, the privacy boundary, output validation, and the agent loop with a mocked Anthropic client - deploy/: systemd unit and nginx site config for production
