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

The annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds a useful caveat that competitor rankings are estimates, but it omits other behavioral details such as data freshness, authentication needs, pagination, or result volume.

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 two concise sentences with no filler, front-loading the core comparison and ending with the estimate caveat. Every sentence contributes useful context.

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 need not be described, and annotations cover the read-only profile. However, for a tool with 19 undocumented parameters and no required-argument guidance, the description leaves major gaps in how to call it correctly.

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?

There are 19 optional parameters with 0% schema description coverage, and the description explains none of them. It gives no meaning for url, days, action, status, date_from/date_to, site_url, sort_by, or other inputs, leaving an agent unable to infer how to invoke the tool correctly.

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 states a specific resource and comparison basis: competitor-tracked keywords versus the user's exact Search Console position, with three result categories. It is clear what the tool does, though it does not explicitly distinguish itself from siblings such as search_get_competitors or search_get_top_queries.

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 description does not state when to use this tool versus alternatives, nor does it mention prerequisites, exclusions, or related sibling tools. Usage is only implied by the gap-comparison framing.

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