getAtjsSettings

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

No annotations are provided, so the description carries the behavioral transparency burden. It does disclose that this is a read operation via 'Retrieve' and gives a sense of the returned content categories. However, it does not mention side effects, permissions, error behavior, or whether the response is complete or partial. For a simple parameterless getter, this is adequate but not rich.

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 sentence that front-loads the core action and resource, then lists useful specifics. Every part contributes meaning; even the trailing 'and other AT.js library settings' usefully signals that the list is non-exhaustive. It is compact without sacrificing clarity.

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?

For a parameterless read tool, the description provides a reasonable overview of what is returned, but it stops short of being fully complete. There is no output schema, so the description carries the burden of explaining the return value; it names several settings but remains vague about the full shape or behavior. Additionally, the broad sibling context offers no guidance to reduce ambiguity.

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 tool has zero parameters and the schema is empty, so there are no parameter semantics to document. The baseline for no parameters is 4, and the description correctly focuses on the output content rather than inputs. No additional parameter-related explanation is needed.

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 uses a specific verb 'Retrieve' with a concrete resource, 'AT.js settings', and enumerates key included fields (client code, decisioning method, timeout, global mbox configuration). This clearly separates it from the similarly named sibling getAtjsVersions, but it does not explicitly call out that distinction. Overall purpose is clear and actionable.

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?

There is no guidance about when to use this tool versus alternatives such as getAtjsVersions or getMbox. The context signals include many sibling tools that could overlap in the AT.js domain, but the description does not provide any 'use this when...' or 'for versions use getAtjsVersions' direction. Usage is only implied by the tool's name and the verb.

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