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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description contributes only the hint that progress counts are included, which is thin given there is no output schema to describe the response shape.

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 front-loaded sentence with no filler or repetition. Brevity here reflects under-specification rather than waste, but nothing needs to be cut.

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 one-parameter read tool with full annotation coverage, the essentials are present. However, with no output schema, the description should say more about what 'progress counts' includes or how this differs from get_batch_results; that gap is a real one for an agent assembling a batch-status workflow.

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% (single required 'id' documented as 'Batch id'), so the schema already carries parameter meaning. The description adds nothing about format, source of the id, or behavior when the id is unknown, so baseline 3 applies.

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?

Specific verb (retrieve) and resource (a batch), plus a phrase naming the payload ('progress counts') that goes slightly beyond the title 'Get batch'. It does not differentiate itself from close siblings such as get_batch_results, list_batches, or list_batch_recipients, which an agent must otherwise infer.

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 when-to-use guidance and no mention of alternatives. With get_batch_results, list_batches, and list_batch_recipients all in the sibling set, the agent gets no help deciding which returns per-recipient results versus aggregate progress.

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