bulk_transfer_create

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

With no annotations, the description fully carries the burden of disclosing traits. It explains SCA polling behavior with wait parameter, auto-resolution of vop_proof_token and client_transfer_id, fallback to pending responses, and the effect of sca_session_token. This is comprehensive and transparent.

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 dense paragraph that front-loads the main purpose and covers essential behavior. It is concise given the complexity of SCA flows and multiple parameters, though a more structured format could improve readability.

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 description thoroughly explains input behavior but omits what the tool returns on success (e.g., a bulk transfer ID). Given the absence of an output schema, this gap reduces completeness. It also does not mention prerequisites like account ownership or beneficiary verification, though these are partially implied.

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%, providing baseline 3. The description adds value beyond schema by explaining the interplay of beneficiary_id vs beneficiary, auto-resolution logic, and the wait polling mechanism, clarifying the semantics of each parameter.

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 'Create a bulk SEPA transfer from a debit account,' using a specific verb and resource. It distinguishes itself from sibling tools like bulk_transfer_list and bulk_transfer_show, which are read-only, and no other create-transfer tool exists among siblings.

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 provides rich context on when to use the tool, including SCA handling, auto-generation of identifiers, and the distinction between beneficiary_id and inline beneficiary. However, it lacks explicit statements about when not to use it or direct alternatives, though the included details implicitly guide usage.

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