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

Annotations already declare readOnlyHint=true and destructiveHint=false, indicating safe read-only behavior. The description adds no further behavioral context, such as response format or pagination, which is acceptable but minimal.

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?

Two short, front-loaded sentences with no extraneous content. Every word earns its place, efficiently conveying the tool's purpose and naming clarification.

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 read-only tool with two parameters, the description adequately covers the purpose and key schema details. The naming clarification is valuable given the sibling tool 'get_business_permissions'. No output schema exists, but the description is sufficient for a simple permission lookup.

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 0%, so the description must add meaning. It mentions 'community' (communityId) and 'usage' (includeUsage) in context, providing some semantic value beyond the schema, but does not elaborate on parameter formats or constraints.

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 it retrieves feature permissions for a managed community, with an optional usage parameter. It explicitly clarifies that 'business' and 'community' are interchangeable, resolving potential confusion with the sibling tool 'get_business_permissions'.

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 notes that 'business' and 'community' are synonymous, which helps differentiate from 'get_business_permissions', but lacks explicit guidance on when to use this tool versus other permission-related siblings like 'list_feature_plan_permissions'.

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