create_vendor

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

With no annotations, the description carries the full burden for behavioral disclosure. It only states the creation action without addressing permissions, duplicate handling, required fields beyond name, mutability, or response format. This is a clear gap for a mutation 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 compact and front-loaded with the primary purpose. The parameter lines are brief and free of fluff, making the structured list easy to scan. However, the formatting could be slightly improved by grouping or marking required fields.

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?

Given 10 parameters, no annotations, no output schema, and no usage guidance, the description is insufficient for correct invocation. Half the parameters are undocumented and there is no explanation of the creation process, restrictions, or results, leaving critical context gaps.

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 description explains 5 of the 10 parameters (name, email, account_number, bank_country_code, financial_details). However, it completely ignores visible, settings, is_active, address_details, and contact_details, and the schema provides no descriptions at all. It adds some value but fails to compensate for the 0% schema coverage.

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 begins with 'Create a new supplier/vendor profile,' which is a specific verb and resource. It clearly distinguishes this from sibling tools like list_vendors and delete_vendor.

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?

No guidance is given on when to use this tool versus alternatives, no prerequisites, and no mention of related operations. The intended use is only implied by the verb 'Create,' so the agent lacks clear decision support.

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