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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, covering the safety profile. The description adds minimal context beyond this, like the fact that it uses Firecrawl and extracts structured data, but does not disclose potential rate limits, external dependency costs, or failure behavior.

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 a single, front-loaded sentence with no redundant phrasing aside from 'Investigate or', which slightly dilutes precision. It earns a high score for being compact and easy to parse.

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 tool has nested objects (options), 4 parameters, and no output schema, the description is far too sparse. It does not explain return values, how prompts interact with extraction, or the meaning of enableWebSearch, making it inadequate for correct invocation in many scenarios.

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%, so the description must compensate by explaining parameters, but it does not. It only hints at the 'url' resource and says nothing about 'prompt', 'options', or 'enableWebSearch', leaving the agent without enough information to correctly populate these fields.

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 clearly states a specific action ('Extract structured data') and resource ('web pages or urls'), and references Firecrawl as the underlying service. However, it does not explicitly distinguish itself from the sibling 'websearch' tool, relying on the word 'Extract' to imply a difference.

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 guidance on when to use this tool versus alternatives like 'websearch' or other chain-specific tools. The description only states what the tool does, not in what context it should be chosen or when to avoid it.

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