Create Vendor

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

Annotations already indicate a non-read-only mutation. The description adds a requirement (minimum a name) and includes an example, which enriches behavioral transparency beyond the annotations. However, it does not detail further behavioral traits like idempotency or side effects.

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 efficient with two sentences plus an example. It is front-loaded with the core purpose. The bilingual repetition slightly reduces conciseness, but overall it is clear and compact.

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?

The tool has a modest parameter set (5) with 1 required, and an output schema exists. The description explains the purpose, required field, and usage context. It lacks detail on validation or error handling, but for a simple creation tool, it is reasonably complete.

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 coverage is 100%, so baseline is 3. The description goes beyond by providing a concrete example with parameter values (name, email, taxId, address), demonstrating the structure and acceptable data. This adds meaning that aids selection and 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 'Create a new vendor/supplier' with a specific verb and resource. It distinguishes from sibling tools like list_vendors, get_vendor, etc., by explicitly stating the creation action.

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 context by mentioning that vendors are used when tracking expenses and purchase orders, giving a clear usage scenario. It does not explicitly list alternatives or when not to use, but the context is sufficient for a creation tool with no direct sibling.

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