batch

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

With no annotations, the description carries the full behavioral burden. It discloses the 500-item limit and the free-tool restriction, but it is silent on important batch behavior such as partial failures, error aggregation, execution order, and whether the PRO trial note affects invocation or cost.

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 the core purpose. Every sentence earns its place, and the limit plus eligibility constraint are stated efficiently.

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?

The core invocation requirements are present, but with no output schema and no annotations, the description leaves batch failure/response behavior and the ambiguous "[PRO - 3 free trials]" note under-explained. An agent might invoke it correctly, but not fully understand what to expect from the result or cost model.

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 coverage is 100%, so the schema already documents both `tool` and `items`. The description adds little parameter-specific meaning beyond restating the item limit and the free-tool requirement, which the schema already contains.

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 is specific and verb-first: "Run any free tool across multiple inputs in one call." It clearly identifies the tool as a batching wrapper, which naturally distinguishes it from the sibling utility tools that operate on single inputs.

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?

The description gives clear context for when to use the tool: when you have multiple inputs for a free tool and want to run them in one call. It also states the key exclusion: only free tools are supported. It does not explicitly name alternatives, but the usage context is strong enough.

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