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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered elsewhere. The description adds nothing beyond the name: it does not say whether output is a list, how many names are returned, whether results are deterministic given seeds, or how the limit interacts with generation.

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 words is not conciseness here but under-specification; there is no front-loaded intent statement, no scope, and nothing for the agent to anchor on beyond the title repeated in the name.

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 carried the burden of explaining the return shape but says nothing about it. For a two-parameter generator with a required 'seeds' array and a numeric 'limit', the definition omits everything an agent needs to call it correctly.

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%: neither 'seeds' (a required array of strings) nor 'limit' (a number with minimum 0) is documented anywhere. The description could have explained that seeds drive generation and that limit caps the number of names, but mentions neither.

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?

'Startup name generator' names a recognizable resource (startup names) and implies the action (generate), so an agent can guess the intent. However, it is a bare noun phrase with no verb, no scope, and no attempt to distinguish it from the many document/calculator siblings in the business_* family.

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?

No when-to-use, when-not-to-use, or prerequisite information is given. The description does not mention that it requires seeds, nor how it relates to alternatives, leaving selection entirely to the tool name.

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