Small graph. Clear behavior.

Type a support message and watch a deterministic LangGraph workflow classify it, fetch policy, draft a reply, review it, optionally revise it, then finalize.

classify — choose category and priority

fetch_policy — load the relevant rule

draft_reply — create a response

review_reply — branch if revision is needed

finalize — return the answer
