vaultix_create_customer

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Create a new customer' implies a write/mutation operation, but it doesn't disclose important behavioral traits like required permissions, whether duplicate customers are allowed, what happens on success/failure, rate limits, or what the response contains. This leaves significant gaps for an agent to understand how to use this tool effectively.

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 extremely concise at just 3 words, which is appropriate for a simple operation. It's front-loaded with the essential action and resource. However, this conciseness comes at the cost of completeness, as it lacks necessary context for proper tool 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 mutation tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what happens after creation, what data is returned, error conditions, or how this tool relates to other customer management tools in the system. The agent would need to guess about important behavioral aspects of this write operation.

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 description coverage is 100%, so the schema already documents all 4 parameters (name, email, document, phone) with their types and descriptions. The description adds no additional parameter information beyond what's in the schema, so it meets the baseline of 3 for adequate but not additive parameter 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 'Create a new customer' clearly states the verb ('Create') and resource ('customer'), which is better than a tautology. However, it lacks specificity about what constitutes a customer in this system and doesn't differentiate from sibling tools like 'vaultix_update_customer' or 'vaultix_get_customer' beyond the basic action verb.

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 like 'vaultix_update_customer' for modifying existing customers or 'vaultix_get_customer' for retrieving customer data. There's no mention of prerequisites, typical use cases, or when not to use this tool.

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