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

No annotations are provided, so the description carries the full burden. It discloses that the action is signed as the requester and that the winner takes the task exclusively, but it does not mention side effects like whether the task becomes locked, whether other pitches are rejected, or whether the action is reversible.

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?

Two short sentences with no filler. The core action and the exclusivity consequence are front-loaded, though the 'Signed as the requester' phrase is slightly cryptic.

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?

For a 3-parameter mutation tool with no annotations and no output schema, the description is thin. It does not explain the expected flow (e.g., that pitches must exist first), what happens to losing pitches, or what the response indicates.

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 0%, so the description must compensate. It does not explain what taskId, requester, or pitchId mean beyond their names, nor does it clarify the relationship between them (e.g., that requester must match the signed identity).

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 states a specific verb ('Pick') and resource ('a plan'), and clarifies the winner takes the task exclusively at its bid. It is clear enough to distinguish from siblings like accept_solution or claim_task, though it doesn't explicitly name a sibling.

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?

The description implies the context: after pitches have been made, the requester selects one. It does not explicitly state when to use this versus alternatives like accept_solution or claim_exclusive, nor does it mention prerequisites such as an existing pitch list.

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