setPrettyPrinterSetting

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

No annotations are provided, so the description must carry the full burden. It only says 'Sets the pretty printer settings,' implying a mutable operation, but does not disclose side effects, persistence scope, prerequisites, or return behavior. This is insufficient for an agent to understand the tool's behavior.

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, making it concise. However, it borders on tautological with the tool name and provides no additional detail or structure. It is efficient but not informative, so it earns a 3.

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?

The tool has only two simple parameters and no output schema, but the description lacks context about the effect of the settings, how they relate to sibling tools, or any practical usage context. It is not complete enough for an agent to decide when to use it.

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% coverage with descriptions for both parameters ('style' and 'indent'), so the schema already documents them. The tool description adds no additional semantic meaning beyond the schema, so the baseline 3 is appropriate.

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' clearly identifies a setter action for pretty printer settings. It uses a specific verb and resource, but does not differentiate from sibling tools like 'prettyPrinterSetting' or 'prettyPrinter' that may serve related purposes.

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. It does not mention that this tool modifies settings, nor does it reference related tools for reading or configuring pretty printer settings. There is no context for when to invoke it.

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