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

With no annotations provided, the description carries the full burden of disclosing behavior, but "V1 Web Crawl" says nothing about crawling semantics, pagination, following links, limits, timeout behavior, authentication, or side effects. An agent has no way to predict what invoking this tool will do.

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 text is short, but this is under-specification rather than effective conciseness. The single phrase provides no useful information and is not structured to help an agent decide whether to invoke the tool.

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 tool with three undocumented parameters, no annotations, and no output schema, the description is grossly incomplete. It omits what a crawl returns, how max_pages and maxTimeout are interpreted, and how this relates to sibling tools.

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?

Schema description coverage is 0%, and the description does not compensate by explaining url, max_pages, or maxTimeout. Units, optionality, and behavior of these parameters are entirely 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 "V1 Web Crawl" merely restates the tool name web_crawl with a version prefix; it does not state a specific verb, output, or scope. It also fails to differentiate from sibling tools browse and fetch, which likely overlap in retrieval behavior.

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 offers no guidance on when to use web_crawl versus browse, fetch, or captcha_solve. There is no mention of appropriate use cases, exclusions, or alternatives, so an agent must guess from the name alone.

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