evil_insult_random

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

The annotations already establish that this is a read-only, idempotent, non-destructive, open-world operation. The description adds only the entertainment-only caution and does not expand on content tone, possible offensiveness, or return behavior beyond what the annotations and schema provide.

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, front-loaded sentence with zero wasted text. It immediately states the action and adds only a brief usage caveat.

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 simple random-content tool with rich annotations and fully documented schema, the definition is nearly complete. It could optionally mention that insults may be offensive or that language support is available, but the essential call context is present.

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 input schema has 100% description coverage for the single optional lang parameter, including its default and supported language codes. The tool description does not mention language behavior at all, so the schema is doing the parameter documentation work and the baseline score of 3 is appropriate.

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 states a specific verb and resource: "Get a random insult." This clearly identifies the tool's function, but it does not differentiate from similar sibling tools such as joke_random, dadjoke_random, or chuck_random.

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 parenthetical "for entertainment only" gives a usage context, implying this is not for serious or professional use. However, it does not explicitly say when to choose this over sibling random-content tools or when to avoid it beyond the entertainment caveat.

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