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

Annotations already communicate that this is a safe, read-only, idempotent operation, so the description does not need to restate those traits. It adds a little extra context by saying the views are 'redacted,' but it does not explain what is redacted, how pagination behaves, or what the response shape looks like.

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?

The description is a single, front-loaded sentence with no filler or repetition. It is concise, though it may be slightly too terse to be fully informative.

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 four parameters, no output schema, and 0% schema description coverage, the description is far too minimal to be complete. It communicates only the basic operation, leaving pagination semantics, the required department parameter, and the meaning of 'redacted' views unexplained.

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 0%, and the description adds no parameter-level meaning. Required department_id, limit, starting_after, and request_id are left entirely undocumented, so the description fails to compensate for the schema's lack of explanations.

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 states a specific action ('List') and a clear resource ('Department invitation views'), and the word 'redacted' adds useful scope about the output. It does not explicitly differentiate from sibling tools, but the naming convention and the absence of other invitation list tools make the purpose reasonably unambiguous.

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 description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. An agent must infer from the name alone that this is the right call for listing department invitations, which is not explicit in the description.

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