thangchung Coffee Shop Customer Lookup Skill
Use this skill when the user asks account-related questions or provides customer identifiers.
Data Access — lookup_customer
Use ToolSearch.Gateway only. Do not call MCP protocol tools directly and do not use CLI fallback.
search_tools("customer lookup", limit: 5)- Pick the discovered
customer_lookuptool and schema. call_tool("customer_lookup", {"query":"<email|phone|name|customer_id>"})
call_tool returns MCP content text containing JSON. Parse that JSON.
Normalize to: {"id":"...","name":"...","email":"...","phone":"..."}
Workflow
- Extract email or customer ID from context.
- Resolve
lookup_customer. Prefer specific lookup over broad browse. - Return normalized summary.
Safety Notes
- Never infer identity from a weak match.
- Never expose unrelated customer records.
- If lookup fails, ask for exact email/customer ID.
