emails_batch_create

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

With no annotations provided, the description carries full burden but only states it's a creation operation. It doesn't disclose whether this requires specific permissions, how failures are handled in batch operations, rate limits, whether emails are actually sent or just stored, or what the response format looks like for a batch operation.

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 a single, efficient sentence that communicates the core functionality without unnecessary words. It's appropriately front-loaded with the main action and resource.

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 batch creation tool with complex nested parameters (0% schema coverage), no annotations, and no output schema, the description is inadequate. It doesn't explain the batch operation semantics, error handling, required fields, or what constitutes a successful creation versus individual failures within 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?

Schema description coverage is 0%, and the description provides no information about the 'inputs' parameter structure. It doesn't explain what properties are required for each email, what the associations field does, or how to format the batch array. The description fails to compensate for the complete lack of schema documentation.

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 action ('Create') and resource ('multiple email records') with the batch operation context ('in a single request'). It distinguishes from non-batch email tools but doesn't explicitly differentiate from other batch email tools like emails_batch_update or emails_batch_read.

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 guidance on when to use this batch operation versus individual email creation (emails_create) or other batch operations. The description mentions 'multiple email records' but doesn't specify optimal batch sizes, error handling, or prerequisites for batch creation.

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