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

Annotations already carry readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the access-scoping behavior (results depend on the caller's membership and on org_id) and the differing data exposure per mode, including member emails and roles. It says nothing about pagination, result limits, or permission requirements beyond membership.

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?

Three tight sentences, front-loaded with the verb and then branching immediately into the no-org_id and with-org_id cases. The field enumerations are dense but each earns its place given no output schema exists.

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 single-optional-param read tool with no output schema, the description does the heavy lifting by enumerating both return shapes (id, name, owner, is_owner, org_id, my_role, member_count, emails; or per-team role values). The remaining gap is result sizing behavior — pagination, caps, or ordering are never mentioned.

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?

Only one optional parameter and schema description coverage is 100%, so the schema already documents org_id fully, including its origin in list_organizations and its effect. The description's explanation of the with/without org_id split duplicates the schema rather than adding new syntax or format detail. Baseline 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 and resource ('List teams') and then disambiguates two distinct behaviors by parameter presence, so the agent can distinguish it from create_organization_team, move_flow_to_team, and list_organizations without opening the schema. The returned fields for each mode further pin down what 'list' means here.

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 clear conditional usage: omit org_id for the signed-in user's teams, supply org_id for every team in an organization. That maps directly onto when each mode applies. It does not, however, name an alternative tool or state when-not-to-use (e.g., versus get_organization or list_organizations).

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