list_hijacklibs

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

No annotations are provided, so the description carries the full burden. It states the operation is a list/read, but it does not disclose output format, source of the data, freshness, pagination, or any other behavioral traits. The description is not misleading, but it is thin on behavioral context.

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 short sentences with no filler. The primary purpose is stated first, and the optional filter is added in the second sentence. Every word earns its place.

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 list tool with one fully documented optional parameter, the description is minimally adequate. However, with no annotations and no output schema, it would benefit from stating what fields are returned or what 'known' means. The lack of usage guidance and behavioral details leaves some gaps, but the low complexity keeps it at a passing level.

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 optional 'type' parameter with the same hijack type values. The description repeats this information without adding meaningful new semantics beyond what the schema provides, so the 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 states a specific verb and resource: 'List all known DLL hijacking candidates.' It also defines the optional filter dimension. However, it does not explicitly distinguish itself from the sibling lookup_hijacklib, which likely handles individual lookups rather than listing all candidates.

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 the tool is for listing candidates and optionally filtering by hijack type, but it provides no guidance on when to choose this tool over alternatives such as lookup_hijacklib or list_lolrmm. There are no exclusions or explicit comparison to sibling tools.

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