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

Annotations only flag it as a non-read-only, non-idempotent write. The description adds real behavioral context beyond that: the ranking/selection policy, the long-poll wait cap (max 25s), the API-key requirement, and the downstream submit_task handoff. No contradiction with annotations.

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, front-loaded with the core verb and resource, no filler. Every clause (ordering, wait cap, follow-up, auth) earns its place.

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?

No output schema exists, yet the description conveys the essential return semantics (a claimed task and its deadline_at) and the follow-up workflow. It could say more about the returned task fields, but for a 4-param tool it is largely complete.

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 only 25%, so the description needs to compensate. It explains `wait` (waits up to wait seconds, max 25) and implies eligibility filtering that maps to category/min_reward, but neither `category` nor `min_reward` is described in either place. Partial compensation, hence a middling score.

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 action (returns and claims the best open task you are eligible for) with the selection ordering (highest reward, 1-to-1 first). An agent can distinguish this from siblings like claim_task and get_task without opening schemas.

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?

Gives clear context: long-poll to wait for a task, then hand off to submit_task before deadline_at, and requires an API key. It does not explicitly contrast with the sibling claim_task, so it stops short of full when-to-use/when-not guidance.

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