pangram_check

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

The description discloses the cost and payment mechanism ('Costs $0.001 USDC via x402'), which is a useful side-effect signal. However, without annotations, it carries the full burden of transparency and fails to mention expected inputs, outputs, or any other behavioral characteristics.

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 short but not effectively concise. The opening phrase 'pangram check' repeats the tool name, adding no value, and the category 'Other Utilities tool' is vague. The cost sentence is the only substantive part.

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?

The description is severely incomplete for a tool with no annotations, no output schema, and a generic parameter schema. It does not explain what a pangram is, what input structure is expected, or what the output represents, making it impossible for an agent to invoke correctly without external knowledge.

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 provides 100% coverage with a description for the sole parameter ('Tool parameters as JSON object'), which is generic boilerplate. Per the rubric, high schema coverage earns a baseline of 3; however, the description adds no specific parameter semantics, leaving the actual required properties undefined.

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 'pangram check — Other Utilities tool' merely restates the tool name with a generic category, providing no verb or resource that explains what the tool does. It fails to specify that it checks whether a text is a pangram (contains every letter of the alphabet).

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 usage guidance is provided; the description does not indicate when to use this tool versus alternatives like anagram_check or palindrome_check, nor any scenarios where pangram check would be appropriate.

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