batch_actions

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It mentions that actions are executed in one call, but it does not explain ordering guarantees, partial failure behavior, atomicity, return values, or what happens if one action fails. These are important unknowns for a batch execution 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 short and front-loaded with the core behavior. However, it includes an unlisted url field and omits timeout, so it is concise but not fully accurate.

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?

For a tool with no output schema and no annotations, the description is incomplete. It lacks information about supported action types, execution semantics, failure handling, and what the caller should expect after invoking the batch.

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?

The schema already documents the actions parameter and its properties in detail, so the description adds little semantic value. It also lists 'url?' as an optional action field even though url is not present in the schema, and it omits the timeout field that is present, which could mislead an agent.

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 that the tool executes multiple actions in a single call, which identifies the verb and resource. It does not explicitly contrast itself with the many sibling single-action tools, so it stops short of full sibling differentiation.

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?

There is no guidance on when to use batch_actions instead of individual action tools such as click, fill, type_text, press_key, or wait_for. The batching benefit is implied by the name and description, but no explicit when-to-use or alternatives are provided.

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