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

Annotations declare readOnlyHint=true, confirming safe read behavior. The description adds value beyond annotations by disclosing that the owner appears via a synthetic row, which is a non-obvious behavioral trait. No contradictions detected.

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 consists of two short, clear sentences. It is front-loaded with the core purpose and includes an important behavioral note without any wasted words.

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 simple tool (one parameter, read-only, with output schema), the description is complete. It covers the action, identification method, and a notable result behavior. The presence of an output schema means return values need not be detailed.

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 description coverage is 100% for the single parameter team_identifier. The description mentions 'by UUID or handle', which mirrors the schema's own description. No new meaning is added beyond the schema, so baseline score of 3 applies.

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 verb 'List', the resource 'members of a team', and the identification method 'by UUID or handle'. It also adds a specific detail about the owner appearing via a synthetic row. Among siblings like add_team_member and list_teams, this tool's function is distinct.

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 does not provide explicit guidance on when to use this tool versus alternatives, such as listing teams or adding members. It lacks context about prerequisites or conditions that might warrant using this tool over others. While the purpose is clear, usage scenarios are left implied.

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