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

readOnlyHint=true already establishes this is a safe read, so the description's burden is lower. It adds the underlying endpoint (GET /team/get/{USER_ID}) and the set of fields returned, which is useful, but says nothing about auth, rate limits, or error behavior on an unknown id.

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?

One compact sentence with the field list front-loaded, followed by the endpoint reference. No filler, though the endpoint line is mostly duplicative metadata for an agent.

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 only one parameter and no output schema, the description compensates well by enumerating the returned fields. The remaining gap is the absence of any guidance on failure modes or follow-up tools, which is minor for a simple read.

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 in the schema as the user's id from workiz_list_team. The description adds no syntax, format, or validation detail beyond that, so the baseline 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?

States a specific verb (fetch) and resource (one team member) and enumerates the returned fields (name, role, field-tech flag, email, service areas, skills, active status). The singular framing implicitly distinguishes it from the sibling workiz_list_team, though it never names the alternative explicitly.

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 implied by 'by user id' and the schema hint that the id comes from workiz_list_team, but there is no explicit when-to-use statement, no prerequisites, and no named alternatives. An agent can infer the workflow but must do so itself.

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