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

No annotations are provided, so the description carries the behavioral disclosure burden. It does disclose the returned data fields and the authorized audience, and it implies a non-mutating listing operation, but it does not explicitly state that no mutation occurs, whether the list is scoped to the current workspace, or how empty results behave.

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 compact sentence with no filler and includes several concrete data points. It is slightly less scannable because it begins with a noun phrase ('Everyone waiting...') rather than an imperative verb, but it is still appropriately brief.

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 listing tool with one optional parameter and no output schema, the description conveys what the tool shows, which fields are present, and who is allowed to see it. It does not explicitly state that this is a read-only list or describe edge cases, but the essential invocation information is present.

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 input schema has 100% description coverage for the only parameter, workspace, so the schema already explains its meaning. The description adds no additional parameter semantics, placing this at the baseline 3.

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 identifies the resource as people waiting to be granted access to workspace tools and enumerates the included fields: request id, email, tier asked for, and message. It clearly differs from action-oriented siblings like request_access and allow_request, though it never uses an explicit verb such as 'list' or 'get'.

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 provides useful context by indicating the tool shows pending requests and restricts visibility to owners and tool admins. However, it gives no explicit guidance about when to use this tool instead of allow_request, request_access, set_access, or other access-related siblings, and no when-not conditions.

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