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

readOnlyHint=true already declares the safety profile, so the bar is lower. The description adds the HTTP verb/path (GET /team-members/{publicUserId}), which corroborates the read semantics, but says nothing about error behavior for a bad id, whether the response is a full object, or any access constraints.

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?

Two tight sentences with zero waste; the identification rule is front-loaded and the endpoint is a useful trailing detail.

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?

With one required param and read-only annotations, the call mechanics are covered. But there is no output schema, and the description does not say what a team member record contains or how a missing/invalid id manifests, leaving the agent to guess the return shape.

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 description coverage is 100% and the single parameter is documented with its exact source (locate2u_list_team_members). The description adds no format or validity detail beyond 'public user id', so it neither compensates for nor exceeds the schema — baseline 3.

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?

States a specific verb and resource ('Get one team member') plus the keying parameter ('by public user id'), and the endpoint path reinforces it. It implicitly separates itself from locate2u_list_team_members via 'one', but never names the sibling, so differentiation is left partly to inference.

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?

Usage is only implied: 'get one' suggests retrieval after a list call, and the schema description points at locate2u_list_team_members as the id source. There is no explicit statement of when to prefer this over the list tool or what happens if the id is unknown.

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