Agent / site visibility snapshot

get_agent_visibility
Read-onlyIdempotent

Returns a 0–100 generative-engine visibility score and estimated LLM mention rate for a URL. Cost $0.01 per call. Not HTTP uptime, TLS, or a credit.

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already indicate read-only, idempotent, non-destructive behavior. The description adds valuable context beyond that: the $0.01 per-call cost and the explicit statement of what the metric is not. This is useful behavioral disclosure for an agent deciding whether to invoke the tool.

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?

Three short sentences, each earning its place: the return value, the cost, and the negative scope. Information is front-loaded and free of filler.

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?

For a one-parameter read-only tool with an output schema present, this description covers what the call returns, the cost, and its boundaries. Nothing essential is missing for an agent to select and invoke it correctly.

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?

Schema coverage is 100%, so the schema already fully documents the single `url` parameter. The description adds minimal parameter meaning beyond restating that the score applies 'for a URL', which is consistent but not additive. Baseline 3 is appropriate.

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?

States a specific verb ('Returns') with a clear resource (generative-engine visibility score and LLM mention rate for a URL), and directly distinguishes itself from HTTP/TLS/credit checks. An agent can immediately understand the tool's core function.

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?

Provides clear exclusions ('Not HTTP uptime, TLS, or a credit'), helping an agent know when NOT to use this tool. It doesn't explicitly name a sibling alternative, but the negative scope meaningfully guides selection among the listed verify/agent tools.

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