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

Annotations already cover safety, yet the description adds real behavioral detail beyond them: ordering (earliest to join first), key-scoped visibility ('a key limited to some agents sees only those agents in agent_ids'), the all_agents vs agent_ids distinction, and the exclusion of pending invitations. This is meaningful context an agent cannot get from the structured fields.

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?

Front-loaded with the verb+resource, then dense supporting detail. Four sentences that mostly earn their place, though the field-by-field enumeration and the visibility rule could be marginally tightened.

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 params, no output schema, and annotations carrying the safety profile, the description supplies everything an agent needs: what is returned, in what order, what is excluded, and how key scoping limits visibility. 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?

Zero parameters, so the baseline is 4. The description usefully explains response fields (all_agents/agent_ids, role, email) which the empty input schema cannot, adding value even though there are no params to document.

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 precise verb+resource ('List your organization's members') and enumerates the returned fields (role, email, agents). The word 'organization' implicitly distinguishes it from the sibling list_agent_members, though the sibling is never named, so the differentiation is inferable rather than explicit.

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 closing 'Read-only: your team is managed in the dashboard' hints at when to use this (inspection only, edits happen elsewhere), but there is no explicit when-to-use versus alternatives guidance or reference to list_agent_members. Usage is only implied.

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