vt_search_files_tool

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

With no annotations, the description carries the full burden. It discloses that advanced search syntax is supported and provides examples, which is useful behavioral context. However, it does not explicitly state that the operation is read-only, nor does it mention rate limits, authentication, or error behavior, leaving gaps in safety and operational transparency.

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 compact and front-loaded with the core purpose, followed by a bulleted list of syntax examples. Every sentence contributes actionable information with no redundant filler or repetition of schema fields.

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?

The output schema covers return values, and the description explains the main complexity (query syntax). However, it lacks any guidance on when to use this tool relative to other VT tools and does not mention operational constraints like pagination or search scope. Given the tool's simplicity and presence of an output schema, this is adequate but slightly incomplete.

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 100% so the baseline is 3. The description adds concrete syntax examples for the 'query' parameter (tag:, positives:, fs:, content:), which enriches meaning beyond the schema's simple 'query string' text. This extra detail supports correct query construction.

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 starts with 'Search for files using VirusTotal Intelligence', a specific verb+resource pair. The advanced syntax examples further clarify the intended function and distinguish it from sibling tools that scan or fetch reports.

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 implies usage for searching files but provides no explicit when-to-use vs alternatives such as vt_get_file_report_tool or vt_scan_file_tool. There are no exclusions or comparative guidance, so the agent must infer the appropriate context.

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