First observedApr 14, 2026

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare read-only, idempotent, and non-destructive behavior. The description adds context that the tool performs public-site scans (network access) and clarifies the scope of comparison (readiness, not live rankings), which goes beyond the annotation hints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences, front-loaded with the core action and outcome. Every word earns its place, with no fluff or repetition of schema information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the output schema exists and annotations are strong, the description sufficiently covers the tool's purpose, scope, and limitations. It mentions the types of outputs (aggregate scores, evidence, signals, issues) without needing to detail return structure, and the exclusion clarifies edge cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema provides 100% coverage with clear descriptions and examples for both parameters. The description does not add additional parameter-level detail, so it meets the baseline for high schema coverage but does not exceed it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: running SEO/AEO readiness scans on two websites and comparing scores, evidence, signals, and issues. It distinguishes from siblings by focusing on comparison of two sites, and explicitly clarifies it is not rank or citation benchmarking.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context that this is for comparing two business websites' readiness, and includes an exclusion ('not observed rank or live citation benchmarking'). However, it does not explicitly name alternative tools (e.g., scan_visibility) or state when to choose this over them.

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

A4.4/5.0

Disambiguation5/5

Each tool has a clearly distinct purpose: scan_visibility handles a single site, compare_visibility handles two sites, and visibility_audit_info provides explanatory context. There is no functional overlap or ambiguity.

Naming Consistency4/5

The two primary tools follow a consistent verb_noun pattern (compare_visibility, scan_visibility). The third tool, visibility_audit_info, uses a noun-based name, which is a minor deviation but still clearly readable and thematically aligned.

Tool Count4/5

With only 3 tools, the server is minimally scoped but appropriately covers its core functionality: single scan, comparison, and informational support. This is on the low end but well-suited for a focused visibility assessment service.

Completeness4/5

The tool set covers the primary operations needed for this domain: scanning one site, scanning and comparing two sites, and understanding the methodology. No critical gaps exist for a stateless scanning service, though historical scans or bulk operations are absent.
