Disambiguation4/5

The three visa_bulletin tools share a source but are clearly differentiated by what they return (chart entry, DV cutoff, lettered notes), and fee/processing-time/edition lookups target distinct data. The only soft overlap is between check_form_edition and list_form_changes (both touch form editions) and between list_form_changes and search_alerts (both surface alerts), but descriptions draw workable boundaries.

Naming Consistency4/5

The set follows a broadly predictable verb_noun pattern (get_fee, get_processing_time, get_visa_bulletin, check_form_edition, list_form_changes, search_alerts). Verbs vary (get/check/list/search) but each is semantically appropriate rather than arbitrary, with only minor deviation from a single convention.

Tool Count5/5

Eight tools is well-scoped for a focused immigration-data lookup service, with each tool covering a distinct data concern (form editions, fees, processing times, visa bulletin variants, alerts). No redundant or padding tools are evident.

Completeness4/5

The surface covers the core read-only data domains (form editions and changes, fees, processing times, visa bulletins, alerts) with good lifecycle support for a data service. Minor gaps remain, such as no direct form/instructions lookup or case-status operation, but these are workable around.

Read-only

Inspect

The edition of a form USCIS accepts today, its accepted-from and rejected-from dates.

Free, no sign-in required. Not legal advice. Source: the form's page on uscis.gov, or a dated web.archive.org capture of that page.
