Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only declare readOnlyHint=false, destructiveHint=true, openWorldHint=true; the description adds the substantive behavioral picture: evidence is mandatory for report kinds and a missing-evidence submission is rejected, judge scoring limits, instant-pay threshold, auto-pay timing, and the late-submission refund outcome. This is well beyond what annotations disclose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four sentences, front-loaded with the triggering condition and then the payout/judging rules; each sentence carries distinct operational information. Sentences are long and dense but nothing is redundant, so it lands just under the top mark.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description compensates by fully explaining what happens after submission (judge score, approval, auto-pay, refund on late submission). Combined with a complete schema, an agent has everything needed to invoke this correctly and anticipate the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the evidence parameter already documents the bug_repro/pr_review/site_walkthrough requirement, so the field documentation is doing the heavy lifting. The description restates the evidence requirement and adds the consequence of omission, which is useful but marginal at the parameter level.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific action (submitting finished work for a bounty you were accepted for) and implicitly scopes it apart from siblings like request_changes, approve_work, and accept_bid. An agent can tell what this tool does and where it sits in the bounty lifecycle without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a strong precondition (finished a bounty you were accepted for), plus rich follow-on context: judge scoring capped at 3 attempts, the 0.95 auto-pay threshold, poster approval, 72-hour auto-pay, and the deadline-refund consequence. It never explicitly routes to an alternative tool (e.g. request_changes or resubmission paths), so it stops short of the 5 bar.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
