Scan Dependencies

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

With no annotations, the description carries the full burden of behavioral disclosure. It identifies OSV.dev as the backend and indicates batch behavior, but does not described read-only semantics, network/API dependency, rate limits, or what happens when no vulnerabilities are found.

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?

A single, front-loaded sentence with no wasted words. It immediately conveys the core action, object, and target service.

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?

No output schema and no annotations exist, so the description should explain more about expected results and operational behavior. It does not mention the return shape, error conditions, or how this tool relates to its siblings, leaving important context for the agent missing.

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 ecosystem parameter is already documented by the schema's enum and description. The description's 'named dependencies (with versions)' adds some meaning to the dependencies array but does not explain version format or the structure of each item beyond what the schema already shows. With 50% schema coverage, the description only partially compensates.

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 states a specific verb ('Batch-check') and a clear resource ('a list of named dependencies (with versions) against OSV.dev'). The batch/list framing differentiates it from sibling tools like check_package or scan_dependency_file, which are likely single-package or file-based.

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?

Although the word 'batch' implies the tool is for dependency lists, there is no explicit when-to-use guidance, no mention of alternatives, and no exclusions. An agent must infer from sibling names rather than from the description.

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