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

The annotations only provide destructiveHint: false, indicating it is not destructive. However, the description does not add behavioral details such as whether the tool is idempotent, requires authentication, sends verification emails, or handles duplicate errors. The description carries the full burden but fails to disclose important behaviors beyond the minimal annotation.

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 efficient sentence of 12 words with no redundancy or unnecessary information. It front-loads the core purpose.

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 has 4 required parameters, no output schema, and minimal annotations, the description is too brief. It fails to explain expected return values, error handling, uniqueness constraints, or post-registration steps (e.g., verification). The description is incomplete for a registration tool.

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 coverage is 100%, and each parameter already has a clear description in the schema. The description merely lists the field names without adding any additional meaning, constraints, or context beyond what the schema provides. Baseline 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 clearly states the action (register) and the resource (new user account) and lists the required fields (name, email, password, organization name). It is specific and distinguishes this tool from siblings like neuron_login.

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 description implies usage for creating a new account but does not provide explicit guidance on when to use it versus alternatives (e.g., when a user already exists, use neuron_login). No exclusion criteria or prerequisites are mentioned.

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