Ethora registration

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'registration', implying a write operation that creates a new user, but doesn't disclose any behavioral traits like authentication requirements, rate limits, error handling, or what happens upon success (e.g., does it return a user ID or token?). For a mutation tool with zero annotation coverage, this is a significant gap.

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 concise and front-loaded, consisting of a single sentence that directly states the tool's purpose and parameters. There's no wasted text, and every word earns its place by conveying essential information efficiently.

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 complexity of a user registration tool (a write operation with no annotations and no output schema), the description is incomplete. It doesn't explain what the tool returns, error conditions, or behavioral aspects like side effects. With no output schema and zero annotation coverage, the description should do more to compensate, but it only covers basic parameter requirements.

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?

The description lists the parameters (email, firstName, lastName) and marks them as required, which adds meaning beyond the input schema that has 0% description coverage. However, it doesn't provide additional semantics like format hints (e.g., email format is implied but not explained) or constraints beyond what's in the schema. With low schema coverage, this partially compensates but doesn't fully address gaps.

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 tool's purpose: 'Ethora registration with email (required), firstName (required), lastName (required)'. It specifies the verb 'registration' and the resource 'Ethora', making the action clear. However, it doesn't explicitly differentiate from sibling tools like 'ethora-user-login', which is a related but distinct operation.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, such as whether this is for new users only, or how it relates to sibling tools like 'ethora-user-login' for existing users. There's no explicit when/when-not usage context provided.

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