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

Annotations already indicate this is a non-destructive, idempotent write operation with no open-world access. The description adds useful context that the request is 'private' and tied to the project owner, but it does not describe what happens after submission, whether the request is visible to others, or what the response contains.

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?

A single well-formed sentence that is front-loaded with the core action and includes the key prerequisite condition. There is no wasted wording.

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 five-parameter mutation/request tool with no schema parameter descriptions and no output schema, the description is too thin. It does not explain the roles of the optional parameters or what happens after submission, leaving significant gaps for an agent to infer.

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% across five parameters, so the description must compensate. It only broadly implies what is being requested ('missing geospatial data') and for whom ('project owner'); it does not explain dataset, geography, requirements, or knownSourceUrl, leaving most parameters undocumented.

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 clearly states the specific action: submitting a private request for missing geospatial data on behalf of the project owner. It implicitly distinguishes itself from catalogue-search tools by saying this is used after search found nothing suitable, though it does not 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 phrase 'after catalogue search found nothing suitable' gives a clear contextual trigger for when to use this tool. However, it does not name the alternative search tool or state explicit exclusions, so it stops short of full when/when-not guidance.

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