Generate a minimal request (curl + Node)

plaid_api_request_example

Construct a minimal Plaid API request from OpenAPI required fields, then output curl and plaid-node examples targeting sandbox.plaid.com. Use the body parameter to override placeholder values.

Instructions

Builds the smallest valid request body for an endpoint from the OpenAPI required fields, then renders it as a curl command and a plaid-node snippet against sandbox.plaid.com. Override fields with body.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A3.5/5.0

Behavior3/5

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

No annotations exist, so the description carries the burden. It discloses that output targets sandbox.plaid.com and that fields can be overridden with body, implying generation rather than execution. However, it does not explicitly state that no network call is made, whether credentials are needed, or what the response format is beyond snippets.

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

Conciseness5/5

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

Two sentences with no filler. The core behavior is stated first, and the override mechanism is appended efficiently. Every clause adds information.

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

Completeness3/5

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

The description covers the tool's main behavior and output well, but with no output schema and no annotations, it should also clarify the format parameter's options and whether the tool executes requests. It is adequate for a simple generator but leaves a few operational details unstated.

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

Parameters3/5

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

Schema coverage is only 33%, so the description must compensate. It adds meaning for body ('Override fields with body') and path ('for an endpoint'), but the format parameter is not described, despite having an enum and default. The title hints at curl/Node, but the schema's format control is left implicit.

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

Purpose5/5

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

States a specific verb ('Builds'), a specific resource ('smallest valid request body for an endpoint'), and the concrete outputs ('curl command and a plaid-node snippet'). This clearly distinguishes it from sibling tools like plaid_api_describe or plaid_docs_search.

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

Usage Guidelines2/5

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

No explicit when-to-use guidance, alternatives, or exclusions are provided. An agent must infer that this is for generating example requests, and nothing distinguishes it from nearby search/describe tools.

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