Each tool targets a distinct area: OAuth, company read, employee listing, salary update, payroll status, and payroll preview. The only potential confusion is qbo_payroll_status vs qbo_payroll_preview, since both concern the dry-run payroll path, but the descriptions clarify that one reports run status while the other produces preview totals and output artifacts.

All tools share the qbo_ prefix and snake_case style, and most follow a verb_noun pattern (read_company, list_employees, update_employee_salary). Minor deviations exist: qbo_oauth is a bare noun and the two payroll tools are noun phrases, but the overall pattern remains predictable and readable.

Six tools is well-scoped for a QuickBooks employee/payroll integration. Each tool earns its place, covering a step in the auth → company → employees → payroll workflow without padding or bloat.

The core workflow is covered: authenticate, read company, list employees, update salary, preview payroll, and check status. Minor gaps like employee creation/deletion, company update, and actual payroll submission are absent, but the payroll submission omission appears intentional given the repeated 'never submits payroll' notes, so agents can still complete the intended workflow.
