repeated_words

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

The only behavioral disclosure is the cost ('Costs $0.001 USDC via x402'). With no annotations, the description fails to explain what the tool does, what inputs it expects, or what it returns, leaving the agent to guess.

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 it is under-specified, not concise. It offers no actionable information beyond cost.

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?

For a text-analysis tool with no output schema and a vague generic parameter wrapper, this description is inadequate. The agent cannot infer how to invoke the tool or interpret results.

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 contains a single generic 'params' object with no inner structure, and the description does not clarify what parameters are needed. This provides essentially no semantic guidance.

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 'repeated words — Other Utilities tool' merely restates the tool name and assigns a category. It does not specify a verb or resource, e.g., 'Find repeated words in a given text.' No distinct function is described, making it indistinguishable from many text-analysis siblings.

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 word_frequency or unique_words. The description omits any context, prerequisites, or exclusions.

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