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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is known. The description adds the 'Public API preview' caveat, which is useful, but does not disclose other behavioral traits such as response structure, rate limits, or prerequisites beyond what annotations imply. This meets the baseline for annotation-backed tools.

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 that includes the HTTP endpoint, action, and a stability note. Every word earns its place with no redundancy or 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 tool with strong annotations and no output schema, the description is largely sufficient. It conveys the resource, action, and preview status. However, it does not mention anything about the response format or any filtering/pagination behavior, and the ambiguous brand_id parameter remains unexplained, leaving slight gaps.

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 coverage is only 50%, with brand_id completely undocumented. The description names workspaceId in the path, but does not explain query, brand_id, or workspace_id. The schema's workspace_id description provides useful guidance, but the description itself adds no parameter meaning, so it fails to compensate for the coverage gap.

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 starts with the exact HTTP method and path, then states the specific action: 'read member and owner-review approval settings.' This is a specific verb+resource with clear scope, distinguishing it from siblings like get_approvals (which likely returns approval items) and update_approval_settings (which writes).

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 makes it clear this tool reads approval settings for a workspace, giving clear context for when to use it. However, it does not explicitly state when not to use it or name alternatives like get_approvals or list_pending_approvals, so the guidance is implied rather than explicit.

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