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

With no annotations, the description carries the full behavioral burden, and it does disclose two concrete traits beyond the schema: cost (1 credit per call) and determinism ('Repeatable with a seed'). It stops short of describing the return payload or error behavior for an invalid style, so it is strong but not exhaustive.

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, no filler, with the core purpose and the valid styles front-loaded before the operational notes. Every sentence adds information the agent needs.

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?

There is no output schema, so the description should have picked up the return-value burden, but it never says the result is a list of names or how many are returned by default. Combined with the undocumented 'count' parameter, an agent can call the tool but cannot fully predict its response.

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%, so the description must compensate. It does explain 'seed' (repeatability) and enumerates all five style values, but it never mentions 'count' (default 10, max 50), leaving one of three parameters undocumented in both the description and the schema.

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 ('Generate character, town or ship names') and scopes it with the chosen style and its enum values. It distinguishes the tool from other random generators in the sibling list (dice_roller, loot_table, xp_curve) by naming exactly what is produced.

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 is implied by the purpose plus the credit-cost note, which tells the agent the call has a price. However, there is no explicit when-to-use or when-not-to-use guidance, no alternative tool named, and no prerequisite or rate-limit context to help route between this and the other generative siblings.

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