get_verifications_bulk_result

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

The description states a read-only retrieval, matching readOnlyHint=true, so there is no contradiction. It adds no behavioral details beyond that – no polling semantics, no rate limits, no note that results may be partial or cached. With annotations already covering the safety profile, the description contributes little behavioral context, so it under-delivers.

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. Every word earns its place and the core purpose is immediately visible.

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, the description and schema together tell an agent what to call and with what argument. However, the meaning of the returned 'results' is unspecified and the distinction from get_verification_result is left implicit. Slightly above minimal but not rich enough to fully orient an agent.

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 single id parameter is fully documented in the schema as 'Batch ID returned from verify_emails_bulk', so schema coverage is complete. The tool description says nothing about the parameter beyond its existence, which is fine because the schema carries the meaning. 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?

States the verb 'Retrieve', the resource 'results of a bulk email verification', and the bulk scope, which separates it from the singular get_verification_result. It does not name the sibling alternatives or the originating verify_emails_bulk call, but the resource is clear.

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 offers no explicit guidance on when to call this tool versus get_verification_result or get_emails_bulk_result. The word 'bulk' implies a batch scenario, but the prerequisite (batch ID from verify_emails_bulk) is only stated in the schema, not the tool description. This leaves routing to inference.

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