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

With no annotations provided, the description bears the full behavioral burden, yet it discloses only that the feed is 'real-time.' It says nothing about whether the operation is read-only, whether it requires a target IP/domain, rate limits, authentication, or what the extraction actually returns. The repeated name contributes no behavioral information.

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 nearly all of it is wasted: the tool name and the phrase 'Attack Surface & Exposed Port Auditor' are duplicated verbatim across a colon and a sentence. There is no front-loaded statement of function before the redundancy.

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 security-auditing tool with zero required parameters and no output schema, the description must explain how the audit target is determined and what data comes back; it does neither. Nothing tells an agent what 'structured items' are or how a perimeter is selected, leaving the tool effectively uncallable with confidence.

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?

There is a single optional parameter (maxResults) and schema description coverage is 100%, so the schema already documents it fully. The description adds no meaning about what an 'item' is or what maxResults bounds, but per the high-coverage baseline a 3 is appropriate.

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 restates the tool name twice ('Cloud Perimeter IP Attack Surface & Exposed Port Auditor ... feed for Cloud Perimeter IP Attack Surface & Exposed Port Auditor') and adds only the vague phrase 'real-time structured data extraction.' No concrete verb+resource statement of what is actually done (scan? report? enumerate ports and CVEs?) and nothing distinguishing it from overlapping siblings such as shodan_internetdb_zero_key_ip_port_cve_scanner or b2b_cyber_insurance_ip_risk_underwriting_scanner.

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?

No when-to-use, when-not-to-use, or alternative-tool guidance appears anywhere in the description. An agent cannot tell from this text whether it should call this tool instead of the several sibling IP/port/CVE security scanners, and there are no prerequisites or exclusions stated.

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