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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds real value beyond that by disclosing the shape and authority scope of the result set (id, name, address, role, with the four role values), which tells the agent what it can do with the output.

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?

A single front-loaded sentence identifies the collection first and the payload second, with no filler. The 'as Settings → Team lists them' clause is slightly wordy but it does anchor the resource to a UI the agent may already know.

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 no output schema and no parameters, the description carries the return-value burden and discharges it (fields plus the role enum). The only thin area is the absence of any dependency note on who may view the team, but as a safe read-only listing nothing essential is missing.

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 tool takes no parameters, so per the rubric the baseline is 4. The schema coverage is 100% and there are no arguments whose meaning could be ambiguous.

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 (list) and resource (the workspace team), and enumerates what each entry contains: user id, name, address and role. It implicitly distinguishes itself from the adjacent list_contacts/search_contacts tools by scoping to 'people of this workspace', though it never names those siblings 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 only implied by the resource it returns; there is no statement of when to prefer this over list_contacts or change_a_members_role, and no prerequisites or exclusions. For a zero-parameter read tool the implied usage is adequate, but the description does no routing work.

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