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

The description goes far beyond the input schema by detailing the three specific output formats (Markdown diff, JSON field paths, Mixed) and explicitly mentioning pagination using a 'next' URL, providing critical behavioral traits that the structured data lacks.

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 highly dense and efficient, placing the primary retrieval purpose first and following it with all necessary technical implementation details (formats, pagination) in a single, well-structured paragraph.

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?

Despite lacking an output schema or annotations, the description is exceptionally complete. It covers the core function, the filtering capability, the detailed return formats, and pagination, giving the agent everything needed to anticipate the results.

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 schema description coverage at 0%, the description is extremely vital. It compensates fully by listing all supported page statuses (`same`, `new`, etc.) and explaining the complex nature of the tracking and results, which the schema cannot convey.

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 purpose is clearly defined as retrieving one specific monitor check and its page-level results. By specifying 'one monitor check,' it differentiates itself from presumed listing tools like firecrawl_monitor_list.

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?

It clearly dictates the scope of use: retrieving detailed page-level results, and implies usage context through the available filters like page status. The focus on 'one check' guides the agent's intent appropriately.

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