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 for behavioral disclosure. It states this is a creation operation but provides no information about permissions required, rate limits, whether emails are actually sent or just stored, what happens on partial failures, or what the response contains. For a mutation tool with complex nested parameters, this is a significant gap in behavioral context.

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 waste. It's appropriately sized for a tool name that already indicates 'batch_create' functionality, though this conciseness comes at the expense of providing necessary context for proper usage.

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 (including required fields, enums, and associations), no annotations, and no output schema, the description is severely inadequate. It doesn't explain what 'email records' mean in this context, whether this sends emails or just creates records, what validation occurs, or what the response looks like. The agent lacks critical information to use this tool effectively.

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 input schema has 0% description coverage, meaning all 1 parameter and its complex nested structure are undocumented in the schema. The description mentions 'multiple email records' which hints at the array structure, but provides no details about what constitutes a valid email record, required fields, or the associations parameter. It 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 multiple email records') and resource ('email records'), and specifies it's a batch operation ('in a single request'). It distinguishes from the singular 'emails_create' sibling tool by emphasizing the batch nature, though it doesn't explicitly contrast with other email batch operations like 'emails_batch_read' or 'emails_batch_update'.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention when batch creation is preferable to individual creation, what prerequisites might exist, or how it relates to other email tools like 'emails_batch_read' or 'emails_batch_update'. The agent must infer usage from the name alone.

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