Each tool maps to a distinct stage of a bounty workflow: browse (list_bounties), inspect (get_bounty), evaluate local work (verify_deliverable), and sign/register (submit_proof). There is no plausible confusion between listing many bounties versus fetching one, or between local verification and on-chain submission.

All four names use a uniform `gibwork_` namespace prefix followed by a verb_noun pattern in snake_case (list_bounties, get_bounty, verify_deliverable, submit_proof). The convention is fully predictable and readable.

Four tools is on the lean side but each earns its place within a narrow bounty-hunting scope, and there is no filler. It sits just below the ideal mid-range, leaving little room for auxiliary operations.

The core discovery-to-submission lifecycle is fully covered, including a verification step most servers would omit. Minor gaps remain: no way to check submission status or withdraw/resubmit a proof, and no agent-side profile or submission history lookup.
