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

There are no annotations, so the description carries the full burden. It discloses the 'random' behavior and the quote content, but it does not mention the quote source, possible failure modes, or whether the result is purely read-only. For a trivial no-param fetch tool, this is adequate but not rich.

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 clear sentence with no superfluous wording. The '[COST: ]' placeholder is noise, but it doesn't obscure the meaning. Overall it is compact and front-loaded.

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 no-parameter random-quote tool with an output schema available, the description is largely sufficient. It leaves unspecified details like quote source or formatting, but these are minor for such a simple, low-risk operation.

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 tool takes no parameters, so parameter documentation is unnecessary. The baseline for a 0-parameter tool is 4, and the description does not need to compensate for any schema gaps.

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 uses a specific verb and resource: 'Get a random Donald Trump quote'. It clearly identifies the tool's purpose and the resource is specific enough to stand apart from quote siblings like get_kanye_quote or get_ron_swanson_quote, though it doesn't explicitly call out that distinction.

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?

Usage context is implied: an agent would use this when it wants a random Donald Trump quote. However, the description provides no explicit guidance about when not to use it or which sibling tool to prefer for more general or categorized quotes.

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