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

There are no annotations, so the description carries full responsibility for behavioral disclosure. It fails to describe what the tool does, side effects, or return values. The only extra detail is the cost ($0.001 USDC via x402), which is a business detail rather than behavioral 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?

The description is extremely brief, but it wastes its length by restating the name and adding a generic category. It is under-specified rather than effectively concise, similar to the 'Process' calibration example.

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?

With no output schema and a generic input schema, the description must provide essential context about inputs and outputs. It provides none, making it impossible for an agent to correctly select and invoke the tool.

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 only defines a generic 'params' object with no properties, and the description does not compensate by explaining expected inputs (e.g., strings to compare). Schema coverage of the generic wrapper is irrelevant without actual parameter documentation.

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 merely restates the tool name ('anagram check') and adds a vague category label ('Other Utilities tool'). It does not use a specific verb or describe what the tool actually does, leaving it indistinguishable from sibling utilities like palindrome_check or word_similarity.

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?

The description provides no guidance on when to use this tool versus alternatives. It only mentions pricing and category, with no context about appropriate use cases, prerequisites, or scenarios.

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