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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the search action and sources, but doesn't describe what the tool returns (though an output schema exists), whether it's a read-only operation, any rate limits, authentication needs, or error handling. For a tool that queries multiple external sources, this leaves significant behavioral gaps.

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 a single, efficient sentence that front-loads the core purpose without unnecessary words. Every part of the sentence contributes directly to understanding what the tool does, making it appropriately concise and well-structured.

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 tool's moderate complexity (searching multiple external sources), no annotations, and an output schema (which reduces need to describe returns), the description is minimally adequate. It covers the what and where, but lacks behavioral context, parameter guidance, and differentiation from siblings, leaving room for improvement despite the output schema's assistance.

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 0%, so the schema provides no parameter descriptions. The description doesn't mention any parameters explicitly, though it implies 'cve_id' through context ('proof-of-concept exploits' suggests CVE lookup). It doesn't explain the boolean flags for source inclusion. With 3 parameters (1 required) and no schema descriptions, the description adds minimal value beyond what's inferable from parameter names.

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 ('Search for proof-of-concept exploits') and specifies the resources/sources ('across GitHub, Exploit-DB, and Nuclei templates'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'check_exploit_availability' or 'lookup_cve', which might have overlapping domains.

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?

No guidance is provided on when to use this tool versus alternatives like 'check_exploit_availability' or 'search_cves'. The description implies usage for finding PoCs given a CVE, but lacks explicit context, prerequisites, or exclusions that would help an agent choose appropriately among the many security-related sibling tools.

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