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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description adds value by revealing access restrictions (FREE businesses blocked) and prerequisites (call check_business_tool_access). This goes beyond what annotations provide, though it does not cover potential side effects or rate limits.

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 relatively concise at four sentences, front-loading the purpose. However, the usage guidelines, while valuable, make it slightly longer than necessary. Overall it is well-structured and readable.

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?

Given the tool has two parameters and no output schema, the description provides essential usage context but fails to explain what the admin status response contains, how to interpret it, or error scenarios. It also omits description for the communityId parameter, leaving gaps in completeness.

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 schema has 0% description coverage, so the description must compensate. It only vaguely mentions 'one or more emails' without specifying the format (e.g., comma-separated) and does not describe the communityId parameter at all. This leaves the agent with insufficient guidance on how to provide parameter values.

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 clearly states the tool checks admin status for one or more emails, and clarifies that business and community are interchangeable. While the purpose is specific, it does not explicitly differentiate from the sibling tool 'get_business_admin_status' which likely serves a similar role for the business context.

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 explicit when-to-use instructions: check business permissions, note that FREE businesses cannot use it, call 'check_business_tool_access' before collecting inputs, and show grace-period warnings and resubscribe links. It also says never proceed when access is blocked, offering clear usage boundaries.

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