Each tool has a clearly distinct purpose: creating jobs, fetching individual customers or jobs, listing entities with filters, and a revenue summary. No two tools overlap in function.

All tools use lowercase with underscores; most follow verb_noun pattern (e.g., create_job, list_customers). 'revenue_snapshot' is a noun_noun exception, but the overall style is consistent and predictable.

With 7 tools covering customers, jobs, invoices, and a revenue report, the count is well-scoped for a focused business management service. It's neither too sparse nor overwhelming.

The tool set lacks update and delete operations for all entities, and there is no way to create a customer or invoice. This creates significant gaps in typical CRUD workflows that agents would likely need.
