check_client_ip

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

With no annotations, the description carries the full burden. It conveys a read-only verification behavior through the verb 'Verify' and specifies the whitelist context, but it does not disclose response format, error handling, or whether blacklist is also considered. For a simple check, this level is acceptable but minimal.

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 sentence, front-loads the action, and contains no unnecessary words. It is perfectly concise and 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 simplicity, one required parameter, and the presence of an output schema to document return values, the description is sufficiently complete. It provides all necessary context for correct invocation.

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 schema has 0% coverage, but the description explicitly identifies ip_address as 'a given client IP address', which adds semantic meaning beyond a bare string type. It clearly maps the parameter's purpose, though it lacks format constraints or examples.

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 uses the specific verb 'Verify' and clearly states the resource (client IP address) and the criterion (allowed by security policy whitelist). It effectively distinguishes this tool from sibling security tools like audit_security_rules and get_security_summary by focusing on a single IP check.

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 implies usage when needing to verify a client IP against the whitelist, but it does not explicitly state when to use this tool versus alternatives or provide exclusions. No sibling tool comparisons are mentioned.

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