paypal_list_transactions

Read-onlyIdempotent

Fetch PayPal transaction records for a project-bound connector account. Use this read operation to retrieve transaction data through the approved, project-specific connector authority.

Instructions

Paypal connector operation list_transactions (platform tool paypal.list_transactions).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Required and must be read; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

TDQS

D1.9/5.0
Behavior3/5

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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the description needs little extra. It adds that effect must be 'read' and mentions an idempotency key, which is consistent, though the approval_ref 'when resuming a write' reference is confusing for a read-only tool. No direct contradiction with annotations.

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

Conciseness3/5

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

The description is reasonably compact and uses a clear argument list, but much of the content is generic and repetitive across connector tools. It is structured but not especially informative.

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

Completeness1/5

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

The description lacks domain-specific context: what 'list_transactions' returns, what filters or query options should go into 'arguments', output shape, and when to pick this over related tools. It is essentially a template wrapper and does not complete the picture for an agent.

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

Parameters1/5

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

Schema description coverage is 0%, and the descriptions are generic boilerplate: 'JSON string of arguments for the connector operation' does not explain what arguments are valid for listing transactions, and fields like project_id/project_ref/connector_account_ref are only restated with vague one-line labels. This does not meaningfully help an agent fill in the parameters.

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

Purpose2/5

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

The name and first line identify the resource/action ('list transactions'), but the description otherwise only repeats the tool name and generic routing/authority language. It does not state what the operation actually does or how it differs from sibling PayPal list tools like list_disputes, list_invoices, or list_payouts.

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

Usage Guidelines1/5

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

No guidance is given for when to use this tool versus the many PayPal and financial sibling tools. The 'routes only through the exact project/account governed connector authority' sentence is an access constraint, not a usage recommendation.

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