virustotal_scan_domain

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

With no annotations, the description should disclose behaviors like authentication (api_key) or rate limits, but it only states the core action. No mention of whether it triggers a scan or retrieves an existing report, or any potential side effects.

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 sentence, which is concise, but it sacrifices necessary detail. It is front-loaded but not sufficiently informative for the agent to use correctly.

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 presence of sibling tools and the lack of an output schema, the description is incomplete. It does not clarify the difference between this tool and virustotal_url_report, nor does it describe the report format or any constraints.

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?

The schema has 0% description coverage for its two parameters. The description fails to explain that 'domain' is the target domain or that 'api_key' is an optional authentication key, leaving the agent to infer from the tool name.

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 'Get a VirusTotal report for a domain' clearly states the action (get a report) and the target resource (domain). It distinguishes itself from sibling tools like virustotal_scan_ip, virustotal_scan_url, and virustotal_url_report by specifying domains.

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 no guidance on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or when to opt for scanning an IP or URL instead.

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