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

With no annotations, the description carries full behavioral disclosure burden. It only says it generates a key, but does not state side effects, whether the key is one-time or persistent, permissions required, or reversibility. The phrase 'texto 1×' is ambiguous and does not clarify behavior. This is a significant gap for a mutation 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?

The description is extremely short (one phrase) but is under-specified rather than concisely complete. It lacks essential context and structure, making it more inadequate than appropriately sized. It is front-loaded with the action but fails to convey necessary details.

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?

Given the tool's low complexity (single optional param, no output schema) and no annotations, the description is still incomplete. An agent cannot determine when to invoke it, what the key is for, or what to expect from the response. The ambiguity of 'texto 1×' further undermines completeness.

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 100%, so the label parameter is fully documented. The description adds no extra meaning beyond what the schema provides, so baseline 3 is appropriate. The 'texto 1×' phrase might relate to the key output, but it does not enhance parameter understanding.

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 action ('Gera API key') and the resource (API key with iptk_ prefix), making the tool's purpose evident. However, it lacks detail about what the key is used for and does not differentiate from potential related siblings like auth_start or auth_verify, though no direct conflict exists.

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 guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions. The description is purely declarative and leaves the agent without decision support.

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