batch_execute

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

No annotations are provided, so the description must fully disclose behavior. It only lists supported actions and says 'constrained sequence' but fails to explain constraints (e.g., max 10 steps, stopOnError default), what happens on failure, or whether state is preserved between steps. The schema contains details but the description adds minimal behavioral context.

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 very short and front-loaded with action, which is good for scanning. However, it is overly terse; a few more sentences explaining parameters or usage context would improve completeness without sacrificing conciseness.

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 complexity of the input schema (multiple action types with varying properties) and the lack of output schema, the description is insufficient. It does not address how to construct the steps parameter, selector format, or error handling. Sibling tools provide individual actions, but no context is given for when to batch them.

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%, meaning the description must add meaning for the parameters. The description does not mention 'steps' or 'stopOnError' at all, only lists action types. This leaves the agent without any explanation of the parameter structure, which is complex (array of discriminated unions).

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?

Clearly states it executes a constrained sequence of browser actions in one call and lists supported actions. However, it doesn't explicitly differentiate from calling individual sibling tools sequentially, though 'in one call' implies batching.

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 explicit guidance on when to use this tool versus individual action tools like click, navigate, etc. The description implies batching multiple actions but does not provide criteria for choosing batch over single actions or mention when not to use.

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