create_invoice_link

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

Annotations indicate a non-read-only, non-idempotent operation, but the description adds no additional behavioral context. It does not mention side effects, required permissions, or the need for payment credentials, so the agent relies solely on the annotations.

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 sentence with no redundancy, earning high marks for conciseness. However, it is so brief that it borders on under-specification, though it still has a clear structure.

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 7-parameter schema, no output schema, and sparse annotations, the description is severely incomplete. It does not explain return format, required parameter semantics, or any behavioral caveats, making it inadequate for correct 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?

With 0% schema description coverage and no parameter details in the description, the agent gets no help understanding what 'title', 'payload', 'currency', or other fields mean. The description only says 'invoice' without mapping to any of the 7 parameters.

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 'Create a link for an invoice' clearly identifies the action (create) and the resource (invoice link), distinguishing it from sending an invoice via send_invoice by focusing on link creation. However, it does not explicitly contrast with sibling tools like create_chat_invite_link, so it falls just short of full differentiation.

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 such as send_invoice or create_chat_invite_link. The description only states what it does, not when to prefer it over siblings or any prerequisites like requiring a provider token.

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