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

With no annotations provided, the description carries the full burden for behavioral disclosure. It does mention that the tool costs $0.001 USDC via x402, which is a key behavioral trait (payment side effect). However, it does not disclose other important behaviors such as whether it is read-only, what data it accesses, or any side effects beyond the cost. The cost disclosure is valuable but not comprehensive.

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 very short (one line), which is concise. It opens with the name and category, then provides the cost. The cost sentence is necessary, but the 'Content & AI tool' part is somewhat redundant with the name. Overall, it is efficient but not entirely free of redundancy.

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 incomplete for a paid AI tool. It lacks any information about the expected input text, the output format, or how it differs from similar siblings. Given there is no output schema and the input schema is a black-box JSON object, the agent cannot confidently invoke this tool. The cost disclosure is helpful but insufficient.

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 has one parameter 'params' described as 'Tool parameters as JSON object'. Since schema coverage is 100% (the single property has a description), the baseline is 3. However, the description adds no information about what keys should be present inside the JSON object. The tool name implies passing text, but the description does not help clarify the actual parameters.

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 only states 'proofread — Content & AI tool', which is a vague category, not a clear function. It does not specify that the tool proofreads text or what input it takes. The name implies the purpose, but the description relies on that rather than stating the verb and resource.

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 does not mention any use cases, prerequisites, or contrast with siblings like 'grammar', 'summarize', or 'paraphrase'. The only added note is the cost, which is not a usage guideline.

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