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 'Create' which implies a write/mutation operation, but doesn't mention permissions required, rate limits, whether emails are actually sent vs. stored as drafts, error handling for partial failures, or what the response contains. This is a significant gap for a batch creation tool.

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 states the core purpose without unnecessary words. It's appropriately sized for a tool name that already conveys the domain ('emails') and operation type ('batch_create').

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 severely inadequate. It doesn't explain what constitutes a valid email record, how associations work, what statuses mean, or what happens after creation. The agent lacks critical context for successful tool use.

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%, so the description must compensate but adds no parameter information. The complex nested schema with 17+ properties and associations is completely undocumented in the description. The agent must infer parameter meaning from property names alone, which is insufficient for proper tool invocation.

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 the batch nature ('in a single request'). It distinguishes from the singular 'emails_create' sibling tool by emphasizing batch creation. However, it doesn't explicitly contrast with other batch operations 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?

The description implies usage for batch creation scenarios but provides no explicit guidance on when to use this vs. singular creation ('emails_create') or other batch operations. There's no mention of prerequisites, limitations, or alternative tools for different use cases.

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