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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds valuable operational context: fetches from a datacenter IP without JavaScript, reads about a dozen public URLs once, and logs the domain and tool name for usage statistics. This goes beyond the annotations without contradicting them.

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 long but every sentence contributes meaningful detail: retrieval methodology, check categories, output format, resource usage, and logging side effects. It is appropriately detailed for a complex scanning tool, though the check list is dense and could be slightly tightened.

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?

For a tool of this complexity, the description is remarkably complete. It explains how the crawl is performed, what checks are run, what metrics are returned, how many URLs are read, and what side effects occur. The output schema covers the return structure, so no critical information 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 100%, and the schema already clearly defines the 'domain' parameter with an example and the 'no path' restriction. The description reinforces that the domain must be public, but it does not add significant semantic meaning beyond the schema.

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 identifies a specific verb and resource: fetch a public domain like search engines and AI crawlers, run 22 weighted checks, and return a 0-100 score with per-check results. This is clear and detailed, but it does not explicitly differentiate itself from sibling tools such as growthr_ai_visibility, growthr_fix_order, or growthr_llms_txt.

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?

No guidance is provided on when to use this tool instead of its siblings. There are no when-to-use, when-not-to-use, or alternative tool references. The description only explains mechanics, leaving the agent to infer selection context.

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