check_ip_threat_intel

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds no behavioral details beyond noting it queries 'feeds'. It is adequate but does not elaborate on side effects like API calls or rate limits.

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?

Extremely concise: one sentence plus two bullet-style parameter lines. No wasted words, and the structure is front-loaded with the main 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?

For a simple tool with no output schema, the description should at least hint at the response format (e.g., threat score, categories) or prerequisites (e.g., API keys). It does neither, leaving the agent with incomplete context.

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 coverage is 0%, so the description must compensate. It explains that 'ip_address' is the IP to check and 'providers' is a comma-separated list with examples (urlhaus, abuseipdb). This adds meaning beyond the schema's bare titles, though more detail on IP format or allowed provider values would be better.

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 states 'Check an IP address against threat intelligence feeds', which is a specific verb+resource combination. It clearly distinguishes from sibling tools that focus on network traffic capture/analysis, DNS, HTTP, etc.

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 on when to use this tool vs alternatives. It does not mention when not to use it, nor does it reference sibling tools like 'scan_capture_for_threats' or explain that this is for external IP addresses.

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