list_loldrivers

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

With no annotations and no output schema, the description carries the full burden. It states the core behavior (list all, optional category filter) but provides no information about return format, pagination, or potential size of results. This is adequate for a simple read-only listing but lacks some behavioral detail.

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 action and resource are front-loaded, the optional parameter is clearly mentioned, and the intended use case is added without bloat.

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 tool with only one optional parameter and no output schema, the description provides sufficient information for an agent to call it: list all drivers or filter by category. The missing return-value details are minor given the simple nature of a list operation.

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 already provides 100% coverage of the single optional category parameter with a description of allowed values. The description repeats this with 'Optional category filter (vulnerable, malicious)' but adds no new param semantics beyond the schema, so a baseline score of 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 clearly identifies the action as listing all known vulnerable/malicious drivers from the LOLDrivers database, which distinguishes it from siblings like lookup_loldriver (single item lookup) and list_lolbas/list_lolrmm (other databases). The stated purpose of BYOVD blocklist generation adds a specific and unique context.

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 an explicit use case: 'Use for BYOVD blocklist generation.' This indicates when to invoke the tool. It does not explicitly contrast it with alternatives or state when not to use it, but the clear use case is sufficient.

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