setPrettyPrinterSetting

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'Sets', implying a mutation operation, but fails to disclose critical traits such as required permissions, whether changes are reversible, side effects, or response behavior. This leaves significant gaps in understanding the tool's impact and operation.

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, efficient sentence with no wasted words, making it appropriately concise. However, it is under-specified rather than optimally structured, as it lacks front-loaded critical information that could enhance usability, such as the tool's purpose or key constraints.

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 the tool's mutation nature, lack of annotations, and absence of an output schema, the description is incomplete. It does not compensate for these gaps by explaining behavioral aspects, return values, or error conditions, making it inadequate for safe and effective use by an AI agent in a complex environment.

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 input schema has 100% description coverage, with clear documentation for both parameters ('indent' and 'style'). The description adds no additional meaning beyond what the schema provides, such as explaining the purpose of these settings or their effects. However, with high schema coverage, the baseline score of 3 is appropriate as the schema adequately handles parameter semantics.

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 'Sets the pretty printer settings' is a tautology that essentially restates the tool name 'setPrettyPrinterSetting' with minimal elaboration. While it identifies the action ('Sets') and resource ('pretty printer settings'), it lacks specificity about what these settings control or their purpose, making it vague compared to more descriptive alternatives.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention sibling tools like 'prettyPrinter' or 'prettyPrinterSetting', nor does it specify any prerequisites, contexts, or exclusions for its use, leaving the agent without direction.

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