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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful content-level disclosure (roles, sub-teams, invitations), but says nothing about pagination, result size, or permission requirements for seeing invitations.

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 the returned content front-loaded and the intended use trailing. The opening 'Who is in this organization' is slightly indirect phrasing rather than a direct statement of the operation, but there is no filler.

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 simple, read-only, zero-required-param list tool with full schema coverage and no output schema, the description is adequate: it says what is returned and what the output is for. It could note the 'capacity' block and pagination behavior, but nothing essential for correct invocation 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?

Schema description coverage is 100% and the single 'include' parameter is documented with its enum and default in the schema, so the description is not required to carry it. The description's mention of members/teams/invites loosely maps to three of the four enum values but omits 'capacity', adding no real semantic value beyond the schema.

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 enumerates the resource contents precisely: people with their role, sub-teams, and pending invitations, so an agent knows exactly what comes back. It stops short of differentiating from close siblings like list_members or get_organization, which also surface organizational people data, so an agent cannot tell them apart without opening schemas.

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?

It gives a concrete downstream use: obtaining ids for assigning a handoff (assignUserId / assignTeamId) and identifying approvers. That is clear when-to-use guidance, but there is no when-not-to-use clause and no pointer to the alternative list_members tool for narrower people-only lookups.

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