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

With no annotations provided, the description carries full burden. It discloses the API key prerequisite and the 'push to any webhook' side effect, but doesn't clarify whether this is a one-time operation or a continuous monitor (despite the tool name), nor does it mention response format, pagination, or potential costs/rate limits. The description adds some context but leaves significant behavioral aspects unspecified.

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 three sentences with a clear front-loaded tagline and a dense capability list. The final sentence provides required API key info and an alternative. It is concise and earns its place, though 'Universal web intelligence' is somewhat generic and could be replaced with a more specific operational statement.

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's high complexity (nested objects, multiple optional capabilities) and the absence of an output schema, the description fails to explain what the tool returns, whether it's synchronous or asynchronous, or whether the webhook is the only output. It also doesn't clarify if analysis/enrichment are optional. The description is too high-level to be fully actionable without additional info.

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 coverage is 80%, so baseline is 3. The description adds meaning by explaining the purpose of parameter groups: 'Firecrawl full power' clarifies source actions, 'any LLM model' contextualizes analysis.model, and 'cross-reference with thousands of prediction markets' gives intent to the enrich object. This goes beyond the schema's field-level descriptions.

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 the tool's core capabilities: 'Scrape any URL (Firecrawl full power), analyze with any LLM model, cross-reference with thousands of prediction markets, push to any webhook.' This is a specific verb+resource formulation that distinguishes it from siblings like enrich_content, which is explicitly named as a free demo alternative.

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 an explicit alternative and condition: 'For free demo, use enrich_content instead.' It also mentions the API key requirement, implying this tool is for users with credentials, while enrich_content serves as a no-key alternative. This is clear usage guidance.

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