search_vulnerabilities

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

No annotations provided, so description must carry the burden. It explains that the tool returns a list of collections (threats) and details ordering behavior. However, it omits information on side effects, authentication requirements, rate limits, or that it is a read-only operation. This is adequate but not comprehensive.

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 well-structured with an Args section. It is concise with no redundant sentences, delivering necessary information efficiently. Every sentence adds value.

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?

Given the presence of an output schema, the description does not need to explain return values. It covers the usage flow with get_collection_report. However, it could be more complete by mentioning pagination or result limits beyond the default.

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?

Input schema has 0% description coverage, so description must compensate. It explains query is required, limit default is 10, and order_by defaults to 'relevance-' with accepted values (relevance, creation_date) and sign usage (+/-). This adds significant meaning beyond the schema, though the query format itself is not detailed.

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?

Clearly states it searches vulnerabilities (CVEs) in the Google Threat Intelligence platform. Distinguishes from siblings by specifying it returns collections that can be used with get_collection_report, differentiating from search_threats and other search tools.

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?

Provides guidance on using get_collection_report after obtaining collections, but does not explicitly state when to use this tool versus alternatives like search_iocs or search_threats. More explicit when-not-to-use guidance would improve clarity.

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