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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the important limitation that the tool runs elsewhere and is a catalog entry, which is useful. However, it does not indicate whether the operation is read-only, whether authentication is required, or what the return payload contains, leaving gaps for a no-annotation tool.

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?

The description is compact at three short sentences with no filler. However, the most important functional statement is placed last, after the ambiguous 'Catalog entry' fragment and the environment note, which slightly weakens front-loading. Every sentence contributes, but the ordering could be improved.

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?

The description offers no output schema and no annotations, and it fails to point the agent to an alternative tool when it declares that this one does not run here. Given the many closely related siblings, the absence of routing guidance is a significant omission. The tool's 'not here' caveat makes that guidance essential.

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 schema has zero properties, so the description's mention of 'the purchaseOrderNumber that you specify' is the only documentation of the key input. This adds meaning beyond the empty schema, but it lacks type, format, or placement details. With 0 parameters, the baseline is 4, and the description meets it by naming the primary input.

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 that the tool returns purchase order information for a specified purchaseOrderNumber, a specific verb and resource. However, the opening 'Catalog entry' and 'Runs in your Kuudo deployment, not here' introduce ambiguity about whether this tool is actually executable in the current environment. It does not explicitly distinguish itself from the sibling 20211228_getOrder, relying mostly on the name.

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 provides an explicit when-not: the tool runs in the Kuudo deployment, not here, so an agent should not invoke it in the current environment. This is clear context, but it does not name an alternative sibling such as getOrders or the 20211228_getOrder. No other usage conditions or exclusions are mentioned.

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