Each tool targets a distinct operation: write submission, local ledger query, auth self-check, and plugin self-description. The only mild overlap is between vod_auth_status and vod_devkit_info, both of which report configuration/environment info, but their descriptions make the split (auth/key status vs. version/host identity) reasonably clear.

All tools share the consistent 'vod_' prefix, which aids grouping. However, the suffixes mix conventions: verb-first (submit_voices, list_submitted) alongside noun-first (devkit_info, auth_status), so the pattern is readable but not fully predictable.

Four tools is a well-scoped surface for a focused feedback-submission plugin with auth and introspection needs. Each tool earns its place, though the set is on the lean side.

The surface covers the core lifecycle: submit feedback, list locally submitted items, verify auth, and report plugin metadata, which supports the stated purpose. Missing per-item detail retrieval or update/cancel operations, but submissions appear intentionally append-only, so gaps are minor.
