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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds that results include status, errors, and warnings, which is genuinely useful context about the returned content, but it offers nothing on permissions, sync prerequisites, or whether data must first be synced via sync_search_console.

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 compact sentence with no filler and the resource front-loaded. It is a fragment and could be tightened into a proper clause, but nothing is wasted.

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 one-parameter read tool with no output schema, the description usefully states the returned data shape (status, errors, warnings), which compensates for the missing output schema. Only the absence of any usage routing keeps it from being fully complete.

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?

With a single site_id parameter at 100% schema description coverage, the schema carries full responsibility for parameter documentation. The description adds no meaning beyond it, so the baseline 3 applies.

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 names a specific resource — submitted sitemaps from Google Search Console — and lists the data returned (status, errors, warnings). This clearly distinguishes it from siblings like get_gsc_metrics, get_gsc_pages, and get_gsc_queries, though it is a sentence fragment rather than a full statement of purpose.

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 tool versus alternatives such as submit_sitemap (its natural counterpart) or the other get_gsc_* readers. No prerequisites or exclusions are stated, leaving usage to inference.

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