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

Goes well beyond the annotations: it discloses the required OAuth scope and its failure mode, that the response confirms only acceptance rather than processing, the async nature of Google's handling, and the full error-dict taxonomy (missing_permission/not_found/rate_limited/auth_error/http_error) with message and hint fields. Annotations only say readOnlyHint=false and openWorldHint=true; this adds the real operational picture.

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 write-verb and scope caveat are front-loaded, then behavior, then error shape, then parameter notes — a sensible order. The enumerated error codes are slightly list-heavy, but each element is actionable rather than filler.

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, yet the description still clarifies that the response only acknowledges receipt and where real status lives, which is the key interpretive gap for an async write. Combined with the error taxonomy and the scope prerequisite, nothing an agent needs to invoke this correctly 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 description coverage is 0%, so the description carries the full burden — and it does: sitemap_url is defined as a full URL inside the configured property, and workspace is explained as a customer slug that is optional when only one workspace exists. Both parameters gain meaning the schema alone does not provide.

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?

Names a specific verb+resource pair ('Sitemap-URL bei Google Search Console einreichen') and immediately classifies it as a write operation, which separates it cleanly from sc_list_sitemaps and sc_delete_sitemap in the sibling list.

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?

Gives a clear prerequisite (webmasters write scope, renew connection if missing) and an explicit follow-up path to sc_list_sitemaps for async status checks. It does not state when-not to use it (e.g. vs. bing_submit_sitemap or sc_delete_sitemap), so it stops short of a full routing rule.

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