Each tool targets a distinct screening concern—aggregate risk, balance errors, Benford distribution, duplicates, and rule metadata. screen_journals conceptually overlaps by applying all rules, but its description clearly frames it as a first-pass triage rather than a replacement for the focused checks.

Four tools follow a clear verb_noun pattern (screen_journals, check_balance, detect_duplicates, list_rules), and all names are snake_case. benford_analysis breaks the pattern by using a noun phrase instead of a verb-object form, though it remains readable.

Five tools is a well-scoped size for a specialized journal-entry screening server. Each tool covers a meaningful stage of the workflow without redundancy or bloat.

The set covers first-pass screening, unbalanced-entry cleanup, population-level Benford testing, duplicate detection, and rule documentation, which forms a coherent lifecycle. A per-entry rule explanation or a way to inspect raw risk factors would be a minor gap, but agents can work around it via screen_journals and list_rules.
