vaultix_create_payment_link

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the amount is in cents but lacks critical details such as authentication requirements, rate limits, whether the link is reusable or single-use, or what happens upon creation (e.g., returns a URL). This leaves significant gaps in understanding the tool's behavior.

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 concise with two short sentences that are front-loaded and waste no words. Every part ('Create a shareable payment link. Amount in cents.') directly contributes to understanding the tool's purpose and a key parameter detail.

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?

Given the complexity of a payment creation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what is returned (e.g., a URL or ID), error conditions, or side effects, making it incomplete for effective agent use despite the concise structure.

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%, so the schema already documents all parameters thoroughly (e.g., amount in cents with minimum, allowed payment methods). The description adds minimal value by reiterating 'Amount in cents' but doesn't provide additional context beyond what the schema specifies, aligning with the baseline for high coverage.

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 action ('Create a shareable payment link') and specifies the resource ('payment link'), making the purpose evident. However, it doesn't explicitly differentiate from sibling tools like 'vaultix_create_charge' or 'vaultix_get_payment_link', which would require mentioning that this is for generating a reusable link rather than a direct charge or retrieval.

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 is provided on when to use this tool versus alternatives. For example, it doesn't compare to 'vaultix_create_charge' for immediate payments or 'vaultix_get_payment_link' for viewing existing links, leaving the agent without context for selection among siblings.

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