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

Annotations already indicate this is a non-read-only, idempotent, non-destructive operation. The description adds useful context about the link being short-lived and including NotePom return paths, but it leaves the external Stripe API side effect implicit. This is adequate but not especially rich.

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 with no filler and no duplication of the title. Every word adds relevant information.

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?

The output schema and annotations cover return values and idempotency/safety traits, so the description does not need to repeat those. However, the absence of usage guidance and parameter semantics makes the overall definition only minimally complete for an agent that must invoke it 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 0%, and the description provides no explanation of 'idempotencyKey' or 'country'. The agent gets no semantic help beyond raw schema constraints, so the description fails to compensate for the missing parameter documentation.

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 verb ('create') and a specific resource ('short-lived Stripe Connect onboarding link'), and adds NotePom return paths. This clearly distinguishes it from the listed sibling tools, none of which perform Stripe Connect onboarding.

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 does not state when to use this tool, what prerequisites exist, or which alternatives might be preferred. The only context is what the tool does; there is no explicit usage guidance or exclusion of other scenarios.

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