sync_vulnerabilities

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

No annotations are provided, so the description must fully convey behavioral traits. It states 'sync' and 'update the cache', implying a write operation, but does not disclose side effects, permissions required, rate limits, or whether the operation is idempotent. The optional 'packages' parameter's effect on behavior (e.g., omitting it syncs all packages) is not explained.

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 efficient sentences: first defines purpose, second provides usage context. No unnecessary words or repetition. Front-loaded with the core action.

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?

With no output schema and no annotations, the description should compensate by clarifying return values, error states, and full scope of the sync operation. It covers the basic need but lacks detail on what the agent can expect after calling this tool, especially for error handling or partial sync behavior.

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 description adds no significant meaning beyond the schema. The schema already describes both parameters adequately (ecosystem with enum, packages as optional array). The description does not clarify behavior when packages is omitted, but 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 the action ('Sync') and the resource ('local OSV vulnerability database for a given ecosystem'). It distinguishes from sibling tools like 'check_dependencies' and 'scan_dependencies' by focusing on cache update rather than analysis.

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 second sentence explicitly advises calling this before checking dependencies, providing clear usage context. However, it does not mention when not to use or alternative approaches, which would improve guidance further.

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