cloak_fill_form

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

No annotations provided; description lacks any behavioral details beyond purpose. Does not mention that optional 'submit_ref' triggers click after fill, nor any side effects or state changes. Very minimal disclosure.

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?

Extremely concise (one sentence) but at the expense of valuable details. Not wasteful, but under-specification reduces utility.

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 no output schema, no annotations, and two parameters including an optional submit, the description is insufficient. Agent lacks info on return values, field validation, error behavior, or whether submit_ref is required for forms without native submit.

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 100% meaning the schema already documents both parameters adequately. Description adds no additional semantics beyond 'fill multiple form fields' – no clarification on ref/value interpretation or order of operations.

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?

Description uses specific verb 'fill' and resource 'multiple form fields at once', clearly indicating bulk operation. Distinguishes from siblings like 'cloak_type' (single field) and 'cloak_click' (submit action). Could explicitly contrast with single-field tools.

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 vs siblings like 'cloak_type' or 'cloak_click' for individual fills or sumbits. Agent must infer usage context from name alone.

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