Read any allowed Printful path

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false. The description adds the crucial allowlist constraint and refusal behavior, which is not in the annotations, and clarifies GET-only, consistent with readOnly. No contradiction found.

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 short sentences that front-load the purpose and then state the constraints. No fluff; every sentence adds necessary information, making it efficient and well-structured.

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 single-parameter tool with no output schema, the description covers the allowed paths, the method, and the refusal behavior. It does not describe response shapes, but that is acceptable given the openWorldHint and the generic nature of an escape hatch. The information is sufficient to invoke it correctly.

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 already provides a complete description of the path parameter (type, maxLength, example), and the tool description does not add further parameter-specific detail beyond enumerating allowed paths, which is more about usage than parameter semantics. With 100% schema coverage, the baseline of 3 applies.

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 it is an escape hatch for read endpoints without a dedicated tool, lists the exact allowed paths, and explicitly says GET only and that anything else is refused. This clearly distinguishes it from sibling tools that handle specific read endpoints, giving an agent a precise understanding of its scope.

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?

Explicitly states it should be used when there is no dedicated tool for the read endpoint, and restricts usage to the allowlist and GET method. It does not name sibling tools individually but the 'without a dedicated tool' condition is clear and actionable, and the sibling list is available separately.

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