JWT Token validieren

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

With no annotations, the description carries full responsibility for disclosing behavior. It only states that it validates a token, but omits what happens with invalid tokens, whether it falls back to the current token when none is provided, or what the return format is. This is a significant transparency gap for a validation 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 a single short sentence with no fluff, but it essentially restates the title 'JWT Token validieren'. While concise in length, it is under-specified and does not earn its place by adding new information, making it only average on this dimension.

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 lack of annotations and output schema, and the presence of many sibling JWT tools, the description is incomplete. It fails to mention expected outputs, error behavior, or any contextual details that would help an agent use the tool correctly in different scenarios.

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 already provides 100% coverage of the single parameter, including that it is optional and uses the current token if not provided. The description adds no further meaning, so the baseline score of 3 is appropriate.

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 the verb 'Validiert' (validates) and the resource 'JWT Token', making the tool's basic purpose evident. However, it does not distinguish this tool from sibling JWT tools like jwt_authenticate or jwt_token_info, so it lacks sibling differentiation.

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?

There is no guidance on when to use this tool versus other JWT-related tools. The description provides no contextual cues, alternative suggestions, or exclusions, leaving usage entirely implied at best.

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