api_jwt_analyze

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

With no annotations, the description carries the full burden of behavioral disclosure. 'Analyze JWT' discloses no behavior: whether it decodes, validates, makes network requests, or returns specific output. This is a significant gap for a tool that likely performs multiple operations on a token.

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 extremely concise (two words) but this is under-specification rather than effective brevity. It lacks essential details, so the conciseness comes at the expense of usefulness.

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?

Even for a simple tool with one parameter and no output schema, the description is incomplete. It fails to explain what analysis means, what the returned result looks like, or any edge cases. A minimal description like 'Decode and display JWT header, payload, and signature' would be far more 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?

The input schema has one parameter 'token' with no description, and schema description coverage is 0%. The tool description does not mention the parameter, its format, or how it is used. The description adds no semantic value beyond the schema's bare property name.

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 says 'Analyze JWT', which identifies the resource (JWT) and a general action (analyze). However, it doesn't specify what analysis entails (decode, verify signature, inspect claims) and doesn't distinguish from sibling api_jwt_crack. This is vague but not a tautology.

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 is provided on when to use this tool versus alternatives like api_jwt_crack. There is no mention of use cases, prerequisites, or exclusions. The description implies it is for analyzing JWTs but offers no decision-making context.

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