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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, covering the safety profile. The description adds that this is an aggregated dashboard spanning queries, pages, coverage, sitemaps, and issues, but says nothing about auth requirements, data freshness, or how it relates to the individual GSC tools.

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?

A single front-loaded sentence with no filler; the long metric list is dense but directly informative. It remains readable and appropriately sized for the tool's scope.

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?

With no output schema and a read-only aggregate tool, the metric enumeration is helpful. However, given the crowded GSC sibling set, the description omits the boundary between this dashboard and get_gsc_pages/get_gsc_queries/get_gsc_sitemaps, leaving an important selection gap.

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 description coverage is 100%, including a thorough description of the 'detail' verbosity parameter, so the schema already does the heavy lifting. The description adds no parameter-level meaning beyond what the schema provides, which is the correct baseline for full coverage.

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 (Get) and resource (Google Search Console dashboard for a site) and enumerates the metric categories returned. It does not, however, distinguish itself from narrow siblings like get_gsc_pages, get_gsc_queries, and get_gsc_sitemaps, which overlap with the listed content.

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?

There is no guidance on when to use this aggregate dashboard versus the narrower GSC siblings, nor any stated prerequisites (e.g., site must be connected to Search Console). The agent must infer usage from the metric list alone.

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