lookup_loldriver

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

With no annotations provided, the description carries the burden of disclosure. It clearly states what the tool does and what it returns (driver details, hashes, CVEs, detection guidance). It does not mention possible limitations such as not-found behavior or data freshness, but for a lookup tool this is reasonably transparent.

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 two sentences with no filler. The key action, resource, and input types are front-loaded, and the BYOVD context is added as a meaningful final sentence.

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 simple one-parameter lookup tool with no output schema, the description adequately explains the return contents and use case. It could be slightly more complete by noting behavior when no match is found, but overall an agent has enough to invoke it correctly.

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 100%, so the schema already documents the 'query' parameter well. The description adds the SHA256 detail and the 'name or hash' semantics, but this mostly restates what the schema already conveys. The baseline of 3 is appropriate here.

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 uses a specific verb ('Look up') with a clear resource ('LOLDrivers database') and explains the query types (name or SHA256). It also clarifies the return value and distinguishes itself from sibling list/search tools by focusing on a single driver lookup.

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?

Provides clear context for when to use this tool: for vulnerable/malicious driver lookup and BYOVD detection. It does not explicitly name alternatives or state when not to use it, but the use case is clear enough for an agent to select it correctly among siblings.

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