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

No annotations are provided, so the description must fully disclose behavioral traits. It mentions HMAC+JWT for authentication but does not state whether the tool is read-only, idempotent, or has side effects. No info on rate limits or error conditions.

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 a single sentence, very concise and front-loaded with the core action. However, it sacrifices necessary details for brevity.

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 the tool has no parameters and no output schema, the description is incomplete. It does not explain how the purchase code is supplied (e.g., via request context or headers), nor does it describe the return value or success/failure indicators. The mention of HMAC+JWT adds technical color but does not compensate for missing operational context.

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 input schema is empty (type: object with no properties), but the description implies a purchase code is needed. This contradiction misleads the agent about required inputs. Schema description coverage is 100% only because there are no parameters, but the description fails to clarify the missing parameter.

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 states it validates a Codinfy purchase code using HMAC+JWT, which is a specific action. However, it is unclear how the purchase code is provided since the input schema has no parameters, creating ambiguity about the tool's actual input method.

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 on when to use this tool versus siblings like check_license_status or list_user_licenses. The description does not specify prerequisites or context for use.

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