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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds no behavioral context beyond those annotations—no auth requirements, pagination, rate limits, or scoping constraints—so it contributes nothing new to behavioral understanding.

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 front-loaded sentence with no wasted words, and the returned-field list is compact. It is essentially a verbatim repeat of the title, so it is concise but not substantively well-structured beyond that.

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 one-parameter read tool with no output schema, the description names the returned fields, which partially compensates for the missing output schema. However, it omits any parameter details and usage guidance, leaving the company argument and invocation prerequisites unexplained.

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 schema has one required 'company' parameter with 0% description coverage. The description implies company-scoping through 'company's teammates' but never explains the UUID format, required nature, or example values, failing to compensate for the schema's lack of parameter documentation.

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 states a specific verb ('List') and resource ('company's teammates'), and enumerates the returned fields. It does not explicitly differentiate from sibling tools such as summer_teammates_names_list or summer_teammates_mailbox_list, so it is clear but lacks sibling routing.

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?

There is no when-to-use guidance, no mention of alternative tools, and no prerequisites or exclusions. The description merely restates the purpose, leaving the agent to infer usage context.

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