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

With no annotations, the description carries the behavioral burden and does provide meaningful specifics: it reports real OSV.dev matches and freshness signals rather than mere placeholders. It does not disclose output format, potential external calls, or any limitations, but the core behavior 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?

Two sentences with no filler; the substantive content is front-loaded. The second sentence is positioned as a value proposition rather than technical detail, but it is still brief and useful.

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 description gives a clear sense of what the tool analyzes and what signals it reports, which is helpful given the absence of an output schema. It does not explain the return structure or how the 'standard' tier differs from sibling risk-report tools, leaving some context gaps.

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 both repo_url and ref are already described in the input schema. The description adds limited extra parameter context beyond emphasizing that the repository must be public.

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 that the tool produces an SBOM inventory, OSV.dev dependency-vulnerability matches, and dependency-freshness signals for a public Git repository. This makes the resource and content unmistakable, though it does not explicitly distinguish this tool from the sibling risk-report variants.

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?

It gives useful context by positioning the tool as a one-shot alternative to a secret-scanning subscription, implying a single-use, public-repo scenario. However, it does not state when to choose this 'standard' report over the 'deep' or 'due_diligence' sibling tools.

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