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

Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds that this tool creates a configuration and includes important prerequisites about free business restrictions and permission checks. This contextualizes the behavior beyond annotations.

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 concise and front-loaded with the core purpose. It includes essential usage guidelines without unnecessary fluff. The one redundancy ('Business and community...') is acceptable for clarity.

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?

While usage guidelines are strong, the description lacks parameter semantics and return value information. Given no output schema and 0% parameter coverage, more detail on inputs and outputs is needed for full 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?

Schema coverage is 0% and the description provides no explanation of the parameters (communityId, payoutAccountType, metadata). It does not add meaning beyond the schema's type constraints. For a tool with 3 parameters and nested objects, this is a significant 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 clearly states the tool creates a payout account configuration for a managed community. The additional note that 'Business and community refer to the same thing' clarifies potential confusion, though it does not explicitly distinguish from similar tools like create_business_payout_account.

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 guidance: check business permissions, call check_business_tool_access before inputs, show grace-period warning and verified resubscribe link, and never proceed when access is blocked. This fully helps an agent decide when to use this tool.

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