Osint Domain Recon

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive. The description adds that it is free and lists the data categories, but it does not disclose other behavioral aspects like rate limits, pagination, or potential failure modes. With annotations covering safety, the added context 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, dense sentence that front-loads the purpose and enumerates the scope. No filler or redundant information; every word 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?

The tool has an output schema (per context signal), so return values are documented elsewhere. Annotations cover the safety profile. The description lists the data categories and indicates it is free. It does not mention that it aggregates multiple services or potential latency, but for a read-only recon tool with an output schema, this is sufficient.

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% description coverage for the 'domain' parameter. The description mentions 'for a domain,' indicating the input, but provides no format guidance (e.g., whether to include scheme or subdomain). Since it's a single, obvious parameter, this is minimally adequate but could benefit from a note on expected format.

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 tool performs reconnaissance on a domain and enumerates the specific data sources (DNS, WHOIS, crt.sh, hosts, email security, geoip). This distinguishes it from the many sibling tools that each focus on a single source, making the 'all-in-one' aggregation explicit.

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 phrase 'All-in-one' implies use for a broad overview rather than a specific lookup, but it never explicitly says when to prefer this over a dedicated sibling tool, nor does it name alternatives or exclusions. The usage context is implied but not stated.

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