update_code_to_pep8

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

The description says 'Update Python code' which implies write/modify, but annotations list readOnlyHint: true, creating a contradiction. No additional behavioral traits disclosed.

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 concise with a single sentence, but it sacrifices essential details for brevity. Could be expanded without becoming verbose.

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 accepts nested objects and has an output schema, the description is insufficient. No information about return values, side effects, or prerequisites, making it incomplete for effective usage.

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?

Description adds no parameter meaning beyond the schema. Schema coverage is 0% with the top-level parameter 'model' lacking a description; nested objects have descriptions but not the required parameter. The description does not compensate.

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 clearly states the tool updates Python code to PEP8 style, specifying verb and resource. However, it does not differentiate from sibling tools like check_syntax or complete_code, which could also relate to code quality.

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 on when to use this tool versus alternatives (e.g., check_syntax, complete_code). The description lacks explicit usage context or prerequisites.

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