audit_dependencies

Scans an npm project's dependencies for known vulnerabilities using OSV. Offers deterministic mock mode for offline use or live mode with retry and caching.

Instructions

Audit the repository dependencies against OSV (api.osv.dev). Supports a deterministic mock adapter (default, no network) and a live adapter (timeout, bounded retry, TTL cache, sliding-window rate limit). Returns the dependency list and the matched vulnerabilities.

Behavior4/5

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

Describes mock vs live adapter behavior (network, retry, cache, rate limits) and return value, compensating for missing annotations. Does not cover authentication or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, no fluff, front-loaded with main action and key details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers adapters and return but lacks explanation of repoRoot path requirements, ecosystem options, and output format. Adequate for simplicity but gaps remain.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Adds meaning to osvMode by explaining mock/live behavior; ecosystem and repoRoot are not described. With 0% schema coverage, description partially compensates.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool audits repository dependencies against OSV and lists adapters and outputs. It distinguishes from siblings by context, though not explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like scan_repository or generate_sbom. Missing prerequisites or scenarios.

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