Most tools target a distinct resource+action, and the setup quartet (get_setup_catalog, inspect_setup, plan_setup, apply_setup) forms a clear lifecycle. The only real friction is between collect_context and inspect_setup (both consent-gated, read-only host reads) and among the three list/catalog tools, though descriptions do disambiguate them.

Nearly all names follow a snake_case verb_noun pattern (list_diagnostics, get_control_catalog, audit_coverage, collect_context, inspect_setup, plan_setup, apply_setup). The lone deviation is the bare verb 'diagnose', which is readable but breaks the two-part convention.

Ten tools is well within a well-scoped range and each maps to a plausible step in diagnosis or setup management. A couple (run_self_test, audit_coverage) feel like auxiliary capabilities rather than core workflow, but nothing is clearly redundant.

Setup coverage is strong end-to-end (catalog, inspect, plan, apply with backups), and diagnostics has rule listing, ranking, context collection and self-test. The main gap is the absence of a remediation or rollback/undo tool for non-setup problems, so a diagnosed hook or plugin fault has no direct fix operation in the surface.
