A3.7/5.0

Behavior3/5

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

The description discloses the key side effect: 'Panel credits the account', which is mutation and aligns with readOnlyHint=false. It does not add much beyond annotations; it omits failure modes, idempotency, or what happens if the session is invalid. With minimal annotations, this is acceptable but not rich behavioral disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that front-loads the timing condition and uses bold for key terms. Every word earns its place, and it is appropriately sized for a simple two-parameter tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that an output schema exists and the tool is a straightforward verify-and-credit action, the description covers the essential when and what. It lacks explicit mention of the create_checkout sibling or potential duplicate-call behavior, but it is sufficient for basic invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description is the only source for parameter meaning. It maps 'checkout session id' to sessionId and names packageId directly, which provides some context beyond the raw property names. However, it does not explain how to obtain these values or their relationship, so it only partially compensates for the schema gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the tool's role: after checkout, pass session ID and packageId so Panel credits the account. This clearly implies verification and credit action, and the 'After Checkout completes' condition gives context. It does not explicitly name the alternative create_checkout, but the purpose is understandable without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a clear temporal condition: use this after checkout completes. This is sufficient context for an agent to know when to invoke it. However, it does not explicitly reference sibling tools like ucode_payments_stripe_create_checkout or state that it should not be used before checkout, so it falls short of a full 5.

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