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

No annotations are present, so the description carries the behavioral burden. It usefully discloses the cost ('$0.025 USDC via x402'), the fixed result count, clean page content, and content hashes. It does not cover failure modes or rate limits, but the key behavioral traits are present.

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 two short sentences, with the core functionality front-loaded and the cost mentioned second. No filler or redundant restatement of the tool name appears.

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?

Given the simple single-parameter schema and no output schema, the description adequately explains what the agent will receive: 5 ranked results with clean page content and hashes, plus the cost. It could add a little more about result ordering or failure behavior, but the essential context is present.

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?

With 0% schema description coverage, the description should compensate for parameter documentation, but it adds no detail about the 'query' parameter beyond the schema's name, type, and length. The parameter name is fairly self-explanatory, yet the description does not clarify accepted formats or intended usage.

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 states a specific action ('Search the current web') and clear outputs ('5 ranked results with clean page content and content hashes'). It conveys the tool's combined search and read purpose, though it does not explicitly contrast itself with sibling tools like web_search or read_url.

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?

There is no explicit guidance about when to prefer this tool over web_search, read_url, or other siblings. The description implies a web search use case but provides no conditions, exclusions, or alternatives.

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