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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds the 'detected flag' return cue and the phishing-kit interpretation context, but nothing about rate limits, permissions, or failure modes.

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?

Three short sentences, front-loaded with what is returned and followed by the domain rationale and the parameter note. Little waste, though the phishing-kit sentence is more flavor than operational detail.

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?

An output schema exists, so return values needn't be spelled out, and annotations cover the read-only/idempotent profile. For a single-parameter getter the description is sufficiently complete; only explicit routing versus sibling scan getters is missing.

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% and the only parameter is titled just 'Scan Id', so the description carries the burden – and it does, stating scan_id is the UUID of a ScanMalware scan. That meaningfully clarifies expected input format beyond the bare schema title.

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?

States a specific verb and resource: retrieve bot-protection and CAPTCHA services detected on a scanned page, with a concrete example (Cloudflare Turnstile) and a detected flag. The scope is distinct from sibling getters like get_technologies_by_scan or get_favicon, though it never names those alternatives explicitly.

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?

Usage is implied by the phishing-kit rationale (these services hide kits from scanners), which hints at when an analyst would care. There is no explicit when-to-use/when-not guidance and no named alternative among the many sibling scan getters.

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