random_quote

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

The description discloses that the tool returns an inspirational quote and requires no input. Since no annotations are provided, the description carries full burden and does so adequately, though it could mention if the quote is truly random or fetched from a source.

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 extremely concise, using only two sentences with no unnecessary words. It front-loads the main action and resource, and every word earns its place.

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 tool is simple with no parameters and a clear purpose. An output schema exists but is not described; however, for a random quote tool, the return format is likely obvious. The description is complete enough for use.

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?

There are no parameters, and the schema coverage is 100%. The description correctly notes 'No input required,' so no additional parameter information is needed.

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 gets a random inspirational quote, and the sibling tools (calculator, current_time, etc.) are all different in functionality, so there is no ambiguity.

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 explicitly states 'No input required,' which implies the tool is ready to use without preparation. However, it does not explicitly say when to use it versus alternatives, but given the unique purpose, it is sufficient.

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