sklearn_add_preprocessing

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

There are no annotations and no output schema, so the description bears full responsibility for disclosing behavioral traits. It only restates the action and gives no information about side effects, file modifications, idempotency, required permissions, or what happens after adding steps.

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 brief and front-loaded with the primary verb and object, but it is under-specified to the point of being unhelpful. It provides almost no structured information beyond what the tool name already conveys.

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 two parameters with one undocumented, no annotations, no output schema, and a large sibling toolset, this description is far from sufficient. An agent cannot confidently determine what steps are added, how they are configured, or what the expected result is.

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?

Schema description coverage is only 50%, with 'directory' documented but 'api_key' left unexplained. The description adds no meaning to either parameter, failing to compensate for the undocumented api_key or clarify why the directory is required.

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 a specific verb ('Add') and resource ('feature preprocessing steps'), which clearly distinguishes this from sibling tools like sklearn_generate_pipeline and sklearn_add_evaluation. However, it does not explicitly mention the target pipeline or what preprocessing steps are included.

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 given on when to use this tool versus sklearn_generate_pipeline or sklearn_add_evaluation. The usage context is only implied by the phrase 'Add feature preprocessing steps,' with no exclusions, prerequisites, or recommended invocation conditions.

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