paypal_list_transactions

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

No annotations are present, so the description carries full burden. It mentions routing details but does not disclose key behavioral traits such as read-only nature, required permissions, pagination, rate limits, or what the underlying API actually returns. This is insufficient for safe invocation.

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 short but includes some extraneous routing information that is of limited value for tool selection. It is not excessively long, but could be more focused on essential usage details.

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 that the tool has an output schema, return values need not be detailed, but the description still lacks critical context about scope (e.g., all transactions vs. date-filtered), pagination behavior, and how to leverage the 'arguments' parameter. The agent is poorly equipped to invoke this tool correctly.

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 only parameter, 'arguments', is described simply as 'JSON string of arguments for the connector operation.' With 0% schema description coverage, the description adds no meaningful semantics—it does not specify expected keys, required fields, or format examples. The agent must guess how to construct valid arguments.

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 name and description clearly indicate the tool lists PayPal transactions. However, it does not differentiate from sibling tools like paypal_list_disputes or paypal_list_payouts, which could confuse the agent about which list tool to use for a given request.

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 paypal_list_payouts or other PayPal list tools. The agent is left without context for tool selection.

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