paymentSessions.void

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It fails to indicate whether the operation is reversible, idempotent, asynchronous, or what status changes occur to the payment session. For a financial mutation tool, this absence of safety and state-change information is a significant gap.

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 extremely brief (5 words) and front-loaded with the action. While not wasteful, its extreme brevity contributes to informational inadequacy rather than efficient communication—it leaves critical gaps that sentences should have filled.

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 financial mutation tool with zero schema documentation, no annotations, and no output schema, the description is inadequately thin. It provides only the operation name without addressing side effects, error conditions, or return value structure necessary for safe invocation.

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?

The input schema has 0% description coverage and the description provides no parameter semantics whatsoever. While the single 'id' parameter is somewhat inferable from the tool name, the description does not compensate for the schema's lack of documentation by specifying what ID is required (format, source) or providing examples.

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 provides a specific verb ('Void') and resource ('Ryft payment session'), clearly identifying the operation's target. However, it fails to differentiate from the sibling tool 'paymentSessions.refund', which is crucial for payment operations where void and refund have distinct temporal and financial implications (pre vs post-settlement).

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?

No guidance provided on when to use this tool versus alternatives like 'paymentSessions.refund', 'paymentSessions.cancel', or when a session is eligible to be voided (e.g., authorization vs captured state). The description lacks prerequisites or exclusion criteria.

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