apikeys_generate_api_key

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

With no annotations, the description discloses key behavioral traits: key shown only once, rate limit, and registered users benefit (500 calls/month). This provides sufficient transparency for a key generation tool.

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?

Four concise sentences, each adding distinct value: action, benefit, storage instruction, rate limit. Front-loaded with the main purpose. No wasted words.

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 one-parameter tool with an output schema, the description provides all necessary context: what it does, how to use the output, and rate limits. No gaps.

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?

Only one parameter (email) with 0% schema description coverage. The description only says 'for the given email address', which adds minimal meaning beyond the schema's required field. No format or validation details are provided, so compensation is poor.

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?

Clearly states the tool generates a DataNexus API key for an email address. The verb 'generate' and resource 'API key' are explicit. Sibling tools (revoke, rotate) have different actions, so purpose is distinguishable without explicit comparison.

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?

Provides important usage instructions: store the key (shown only once) and use it as the X-DataNexus-Key header. Also mentions rate limit (3 keys per IP per 24 hours). Does not explicitly state when not to use, but context is clear.

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