contacts_batch_create

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

With no annotations, the description carries the full burden of behavioral disclosure. It only mentions the action and expected dict keys, omitting permission requirements, partial failure behavior, idempotency, or any side effects beyond creation.

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 two sentences, front-loaded with the primary action, and every word adds value. No redundant or filler content.

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 mutation tool with no annotations, the description is adequate for basic usage but lacks guidance on validation, error handling, or batch semantics. The output schema covers return values, so that omission is acceptable, but the missing operational context prevents a higher score.

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 schema is minimal (array of objects with additionalProperties allowed), and description coverage is 0%. The description compensates by listing the expected fields (givenName, familyName, email, phone, organization, title), which adds meaning beyond the schema. However, it does not specify required fields or format constraints.

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 tool's action ('Create multiple contacts at once') with a specific verb and resource. It distinguishes itself from the sibling tool contacts_create by emphasizing batch operation.

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 phrase 'Create multiple contacts at once' implies use when batching is desired, but it does not explicitly contrast with contacts_create or mention when not to use it. No alternative tool is referenced.

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