Get supplier

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

Discloses error behavior (400 returns verbatim error message) and references API documentation. No other behavioral traits mentioned, but with no annotations, this provides reasonable transparency.

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?

Two concise sentences. First sentence conveys purpose and endpoint; second provides error handling guidance. No filler or redundant information.

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 simple single-parameter GET tool, the description covers purpose, endpoint, and error handling. It could mention typical response fields, but references API docs. Sufficient for basic usage.

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% and describes the 'id' parameter as 'The supplier id.' Description adds no additional semantic meaning beyond the schema, maintaining baseline.

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?

Description states 'Get a single supplier by id (GET /suppliers/{id})' which clearly specifies the action and resource, distinguishing it from sibling tools like loyverse_list_supplier.

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?

Implied usage context via the endpoint and error handling, but no explicit guidance on when to use this tool versus alternatives like list_supplier or create_supplier.

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