extractMethodPreview

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 mentions 'previews,' implying a read-only or non-destructive operation, but fails to detail what the preview entails (e.g., output format, side effects, or any constraints like rate limits). This leaves significant gaps in understanding 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, efficient sentence that directly states the tool's purpose without any unnecessary words. It is front-loaded and wastes no space, making it highly concise and well-structured.

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 lack of annotations and output schema, the description is incomplete. It doesn't explain what the preview returns, how it differs from related tools, or any behavioral nuances. For a tool with no structured support, this minimal description fails to provide sufficient context for effective use.

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 the 'proposal' parameter clearly documented as 'The extract method proposal.' The description adds no additional meaning beyond this, but since the schema is comprehensive, a baseline score of 3 is appropriate as it doesn't detract from the existing documentation.

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 states the tool 'previews an extract method refactoring,' which clearly indicates its purpose as a preview operation for refactoring. However, it lacks specificity about what resources or inputs are involved beyond 'extract method,' and it doesn't differentiate from sibling tools like 'extractMethodEvaluate' or 'extractMethodExecute,' making it somewhat vague.

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 such as 'extractMethodEvaluate' or 'extractMethodExecute.' There is no mention of prerequisites, context, or exclusions, leaving the agent without clear usage instructions.

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