There is exactly one tool, so there is no possibility of misselection between tools. Its purpose—read-only polling of sequencer events across four named vendors—is stated explicitly and unambiguously.

The single tool follows a clear verb_noun convention (poll_sequencer_events) in snake_case. There is no competing convention to conflict with, so the naming is fully predictable.

The narrow read-only polling domain can legitimately be covered by one tool, but a single tool is thin: there is no separate way to check vendor connection status, list available vendors, or page through results without doing a full billed pull. The surface is defensible but minimal.

For a read-only event ingestion tool, the surface is essentially complete: it returns per-event rows plus a run summary with per-vendor status and errors. Minor gaps remain—vendor/connection discovery and result filtering must be inferred from the summary row rather than queried directly.
