ip_reputation

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

No annotations are provided, so the description carries full burden. It discloses the dependency on a third-party API key but does not mention rate limits, error handling, or whether the operation is read-only. Minimal transparency beyond the basic action.

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 sentences: first states purpose, second states prerequisite. No unnecessary words, front-loaded with the core action. Efficient and clear.

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?

The tool has an output schema (known from context), so the description does not need to detail return values. It covers the essential context (purpose and API key requirement). Could mention additional details like supported IP versions or potential limitations, but overall adequate for a simple one-parameter tool.

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%. The description implicitly mentions the IP address parameter but adds no format details (e.g., IPv4/IPv6), constraints, or examples beyond the property name. For a single parameter tool, the description provides only minimal added value.

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 (check), the resource (IP address), and the context (malicious reputation via AbuseIPDB). It distinguishes from sibling tools like whois_lookup or port_scan by focusing on reputation.

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 mentions a prerequisite (ABUSEIPDB_API_KEY) but does not explicitly state when to use this tool versus other sibling tools. The purpose implies when to use it, but no alternatives or exclusions are provided.

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