B3.1/5.0

Behavior2/5

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

With no annotations provided, the description bears the full burden of describing behavior, but it only states that an integration is created. It does not mention authentication requirements, idempotency, validation, side effects, or what happens on success or failure. This is minimal behavioral disclosure for a mutating operation.

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?

The description is a single sentence with no filler or redundant language. It front-loads the primary action and includes a distinguishing detail about the payload convention. Every word earns its place.

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

Completeness2/5

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

Given two required parameters, a nested arbitrary-shape payload, no output schema, and no annotations, the description is too thin. It fails to explain valid environment values, the expected Nango payload contract, return behavior, or how to verify success. More context is needed for the agent to invoke this tool correctly in practice.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It hints that payload should follow the 'Nango API payload shape,' which adds some meaning, but it does not explain the environment parameter or the payload structure beyond an external reference. This leaves the agent with insufficient information to construct valid arguments confidently.

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?

The description states a specific verb and resource: 'Create a Nango integration.' This clearly distinguishes it from siblings like update_integration, delete_integration, list_integrations, and get_integration. Adding 'using the Nango API payload shape' also helps differentiate it from other create_* tools and ties it to the Nango domain.

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?

There is no guidance on when to use this tool versus alternatives such as update_integration or delete_integration. No conditions, prerequisites, or exclusions are mentioned, leaving the agent to infer the appropriate create path from the tool name alone.

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