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

With no annotations provided, the description carries the burden of behavioral disclosure. It adds a useful architectural fact: execution happens in the game checkout, not on this host, which affects how the agent interprets the result. However, it does not disclose polling semantics, whether repeated polling is expected, potential side effects, or what error states may occur.

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 the primary action front-loaded and a second sentence adding useful architectural context. There is no filler or redundancy, though the second sentence could arguably be folded into a richer overall description.

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 tool with two parameters and a rich set of 33 sibling tools, the description is too thin. It does not explain parameter semantics, when polling is appropriate, how it relates to hydracept_project_request_operation, or what kind of operation lifecycle it monitors. The output schema helps with return values but cannot compensate for the missing guidance on invocation context.

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?

The input schema has 0% description coverage, and the description mentions no parameters at all. It does not explain the difference between operation_id and project_id, nor provide any guidance on the meaning or required format of these fields. The description adds nothing beyond what the schema already exposes structurally.

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 ('Poll') and resource ('a project operation'), clearly indicating the tool checks the status of an operation. It is distinguishable from the sibling hydracept_project_request_operation, which creates/requests operations rather than polling them. However, it does not explicitly name or contrast itself with that 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 phrase 'Poll a project operation' implies the tool should be used after an operation has been initiated, likely by hydracept_project_request_operation. The note that execution happens in the game checkout gives contextual context but does not explicitly state when to use this tool versus alternatives or mention any exclusions.

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