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

Annotations indicate this is a non-read-only, non-destructive operation, but the description adds no behavioral context beyond that. It does not disclose whether the scan is asynchronous, if it returns a scan ID, or if there are rate limits, which are essential for a submission tool.

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 only six words, which is extremely concise but under-specified. It does not earn its place by adding value beyond the tool name, as it provides no actionable information. It is more under-specified than appropriately concise.

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 four parameters and an output schema, the description is far from complete. It does not explain the scan submission workflow (e.g., subsequent calls to wait_for_scan or get_scan_result), nor does it describe possible options or scan types, leaving the agent without enough context to use the tool effectively.

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 only mentions 'URL', ignoring the other three parameters (options, scan_type, user_agent). It does not explain the meaning of these parameters or their defaults, which is a significant gap for an agent trying to invoke the tool correctly.

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 action ('Submit a URL') and the purpose ('for scanning'), making it obvious what the tool does. However, it does not distinguish it from the sibling tool 'submit_scan_report', which could cause confusion about which submission tool to use.

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 gives no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or workflows. There is no mention of how it differs from submit_scan_report or wait_for_scan, leaving the agent without context for selection.

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