encoding_decoding_jwt

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

Describes read-like operations (decode, parse, validate) and no destructive actions. Lacks details on required permissions, token format expectations, or error behavior. No annotations provided, so description carries burden but is moderately informative.

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?

Concise three-sentence description. First sentence includes menu ID and tool name, second covers functionality, third provides a pointer to more info. Efficient and front-loaded.

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?

Lacks output schema, parameter formatting details, and error scenarios. Relies on describe_tool for completeness, but as a standalone description it leaves out important context about return values and usage nuances.

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 sole parameter 'token' is implied to be a JWT string by the description ('decode and analyze JWT'). However, no further details on expected format, examples, or constraints. Schema coverage is 0%, so description helps but is minimal.

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?

Clearly states 'decode and analyze JSON Web Tokens (JWT)' with details on parsing header, payload, signature, and validating structure. Distinguishes from sibling decoding tools and the nearby security_jwt_generator_validator.

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?

Provides a pointer to describe_tool for full guidance but does not explicitly state when to use this tool over alternatives (e.g., security_jwt_generator_validator) or exclude scenarios. Usage context is implicit from the decoding focus.

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