project_zero_search

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

No annotations are provided, so the description carries the behavioral burden. It goes beyond a simple search description by disclosing that the tool automatically extracts MITRE TTPs, CVEs, and IOC markers, which meaningfully sets expectations about what the tool does with search results.

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?

One sentence, front-loaded with the core action and resource, with no filler. The added extraction behavior is stated compactly and earns its place.

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?

For a simple two-parameter search tool with no output schema, the definition is largely complete: it identifies the source, the search mode, and the automatic enrichment behavior. It does not describe the exact output format, but that is not critical for correct invocation here.

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 input schema already fully describes both parameters: query as a search keyword/CVE/vulnerability name, and limit with default and max. The description reinforces that this is a keyword search but adds little beyond the schema, so 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 names a specific verb ('Search'), a specific resource ('Google Project Zero vulnerability research blog'), and the mode ('by keyword'). It also adds a distinct processing behavior—extracting MITRE TTPs, CVEs, and IOC markers—which separates it from generic blog-search tools and most siblings.

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 description gives clear context: use this tool when you need to search the Google Project Zero research blog by keyword. It does not explicitly name alternatives or exclusion criteria, but the unique source makes the intended usage obvious.

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