emails_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. 'Create a new email record' implies a write/mutation operation but reveals nothing about permissions required, whether creation is idempotent, what happens on failure, rate limits, or what the response contains. This is critically inadequate for a mutation tool with complex parameters.

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 maximally concise at 4 words with no wasted language. However, this conciseness comes at the cost of being severely under-specified for such a complex tool. Every word earns its place, but far too few words are present.

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 mutation tool with 2 complex parameters (0% schema coverage), no annotations, no output schema, and no sibling differentiation, the description is completely inadequate. It provides minimal purpose statement but lacks all necessary context about behavior, parameters, usage, and expected outcomes that an agent needs to invoke this tool correctly.

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%, meaning parameters are completely undocumented in the schema. The description mentions no parameters at all, failing to compensate for this gap. With 2 parameters (including a complex nested 'properties' object with 15+ fields), the agent has no semantic understanding of what inputs are needed or their purposes.

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 'Create a new email record' states the verb ('Create') and resource ('email record'), but it's a tautology that essentially restates the tool name 'emails_create'. It doesn't provide any distinguishing details about what constitutes an email record or how this differs from sibling email tools like emails_batch_create or emails_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 zero guidance on when to use this tool versus alternatives. There's no mention of prerequisites, appropriate contexts, or comparison to sibling tools like emails_batch_create for bulk operations or emails_update for modifications. The agent receives no usage direction.

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