A4.4/5.0
Scored across 3 tools
Disambiguation5/5
ask_henry and search_sources have clearly distinct outputs—one returns a synthesized cited answer, the other returns raw passages—while connect handles session state. No two tools appear to do the same thing.
Naming Consistency4/5
Two tools follow a verb_noun pattern (ask_henry, search_sources), while connect is a bare verb—a minor deviation. All names are lowercase snake_case and readable, so the set remains predictable.
Tool Count5/5
Three tools cover the core interactions for this specialized assistant: ask, search, and session connect. This is well-scoped and avoids redundancy.
Completeness5/5
For the stated domain of F-1/J-1/OPT/CPT questions, the set provides both direct Q&A and transparent source search, plus session continuity. There are no obvious dead ends for the intended workflow.
