fill_form

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

With no annotations, the description carries the full burden of behavioral disclosure. 'Fill out forms in batches' implies a mutation (data entry), but it omits critical details: whether it submits forms, what happens to existing data, error handling, or any side effects. This is insufficient for a write tool.

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, front-loaded sentence with no wasted words. However, it is too terse for the complexity of the tool, and its brevity fails to convey necessary operational context.

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 a nested object parameter, no annotations, and no output schema, the description is inadequate. It does not explain how to structure the 'fields' object, what 'submit' does, or what the tool returns, leaving significant gaps for correct invocation.

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 0% and the description does not mention either parameter. The 'fields' object structure and the 'submit' boolean are completely undocumented, leaving an agent with no guidance on expected input format or behavior.

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 (Fill out) and resource (forms) with a scope qualifier (in batches). It distinguishes the tool from its sibling 'fill' (likely single-field) by implying a form-level, batch operation. However, it does not explicitly differentiate from other form-related siblings or clarify what 'batches' means.

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 when-to-use guidance is provided. The description does not explain when to choose this tool over alternatives like 'fill', 'type', or 'batch', nor does it state any prerequisites or conditions. It only implies a batch context without elaboration.

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