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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint. The description adds the 'bounded page' behavior, indicating pagination, which is not in the annotations. This adds useful context beyond the structured data, though it could be more specific about pagination mechanics.

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 a single, well-structured sentence that is front-loaded with the action and resource. Every word adds value; there is no redundancy or filler.

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?

Given the tool's simplicity (list with pagination) and the presence of annotations, the description covers the essential purpose and return content. It does not describe return format or pagination details, but no output schema exists and the parameters are simple. A minor gap is the lack of explicit parameter mapping, but overall it is reasonably complete for the tool's scope.

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%, and the description does not explicitly mention limit or offset. The phrase 'bounded page' hints at pagination but does not explain how parameters control it. The parameter names are standard, but the description fails to compensate for the lack of schema descriptions, leaving parameter semantics largely implicit.

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 tool lists a bounded page of DigiKey manufacturers and their manufacturer IDs. The verb 'List' is specific, and the resource is clearly identified, distinguishing it from sibling tools like search_products or list_categories.

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 the core functionality but no explicit guidance on when to use this tool vs alternatives. There are no sibling comparisons or contextual cues. Usage is implied by the tool's name and description, but no when/when-not guidance is given.

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