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

With no annotations, the description carries the full burden. It usefully discloses cost (free) and the return shape {decision, accepted, verdict, reason}, which compensates for the missing output schema. It does not say whether calling validate persists a verdict, whether validation is deterministic, how ties/uncertainty are handled, or what happens when acceptance rules are absent.

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?

Three tight sentences, no waste, with the most distinctive attribute (FREE) and the decision semantics front-loaded. The return-shape sentence is compact and informative.

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?

Adequate: return values are enumerated to offset the absent output schema, and the schema covers inline-task vs fetched-task mechanics. Still thin for an 8-parameter, nested-object tool with no annotations, since side effects, permissions, and the 'attempt under arbitration' lifecycle context are left unexplained.

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 coverage is 75%, so the schema already documents most parameters, including the notable 'acceptance supplied inline; used instead of fetching the task' behavior. The description reinforces the task/result/acceptance concepts but adds no format or precedence detail beyond the schema.

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?

States a specific verb and resource: decide accepted/rejected for a delivered task result against the task's published acceptance rules. An agent immediately knows this adjudicates results rather than fetching, listing, or packaging anything, and no sibling competes for that job.

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?

Usage is implied by 'delivered task result' and the 'FREE (no payment)' qualifier hints at a paid alternative path, but there is no explicit when-to-call guidance, no statement of who may call it, and no exclusions (e.g., before a result is delivered, or when the task has no acceptance rules).

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