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. It only mentions per-item success/failure details, omitting important aspects like ordering, atomicity, rate limits, or error handling for the batch as a whole.

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?

A single sentence of 16 words efficiently conveys the core purpose. No unnecessary details, and it is front-loaded with the main action.

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 simplicity (1 required param) and no output schema, the description adequately states return details. However, it lacks information about maximum batch size, required fields in each item, and whether results are ordered.

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%, and the description adds minimal value beyond what the schema provides (e.g., mentioning forwarding to a specific endpoint). It does not elaborate on the structure or constraints of the items array.

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 the tool runs multiple simulation requests in one call, distinguishing it from the sibling 'simulate' which likely handles single requests. The verb 'run' and resource 'simulation requests' are specific.

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 implies batch processing for multiple simulation requests, but it does not explicitly state when to use this over alternatives like 'simulate' or provide scenarios where batch is preferable. No exclusions or prerequisites are mentioned.

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