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

Beyond the readOnlyHint and destructiveHint annotations, the description discloses the required manage_automation permission, explains that nextSteps is ordered and empty means ready to sell, and lists three setup actions that cannot be done by any tool. This adds meaningful behavioral and permission context.

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 front-loaded with the verb, resource, and returned fields, then adds permission and setup context without redundancy. The manual-steps sentence is long but high-value for an agent trying to understand what remains outside tool control.

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?

There is no output schema, but the description enumerates the important returned setup fields and defines nextSteps semantics. Combined with the fully documented single parameter and safety annotations, it gives an agent enough information to select and invoke the tool correctly.

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 description coverage is 100%, and the applicationId parameter is already fully documented in the schema, including app-scoped versus personal key defaults and the MCP_APPLICATION_REQUIRED failure mode. The description adds only an implicit 'of an application' scope, so the schema carries the parameter semantics.

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 states a specific read operation on a specific resource: the Tribute one-time payment setup of an application. It enumerates the returned setup details (connection status, notification link confirmation, products, contact variables, nextSteps) and positions itself as the starting point for Tribute-related work.

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 clearly says to start here for anything about Tribute and notes the manage_automation permission requirement, which gives useful invocation context. It does not explicitly route to or exclude sibling tools such as list_tribute_account_products, list_tribute_purchases, or update_tribute_connection.

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