Create Member

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

The annotations state readOnlyHint=false, indicating a write operation, and the description's 'Add' aligns with that. The description adds the detail 'Members are anonymized by default,' but this is already captured in the schema's anonymized property default, so it adds no new behavioral context. It doesn't disclose side effects, conflict handling, or permission requirements.

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 very concise—two sentences with no filler. It leads with the core purpose, then lists required fields and a default behavior, all in under 30 words. This is efficient, though the field list is a bit perfunctory.

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 19 parameters, 11 required, no output schema, and low schema coverage, the description is under-specified. It doesn't describe what a member success story entails, how to structure the content fields, what the tool returns, or how it interacts with other member tools. This leaves an agent without enough guidance to invoke it confidently.

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?

With schema description coverage at 37%, the description should explain key parameters, but it only repeats the required field names from the schema. It doesn't provide any additional meaning for fields like city, name, initials, quote, or category, nor for optional fields, leaving significant ambiguity for an agent.

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 uses a specific verb 'Add' and identifies the resource as 'member success story,' clearly stating the tool's function. However, sibling tools like create_testimonial also deal with success stories, and the description doesn't differentiate between them, so it's clear but not fully distinguished.

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 create_member versus update_member, delete_member, or create_testimonial. It only states what it does and lists required fields, with no context about scenarios or alternatives.

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