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

Annotations already declare that this is a non-read-only, open-world, non-idempotent write operation, covering the safety profile. The description adds that resubmission is possible and that the sitemap URL must be complete, but it does not disclose auth requirements, rate limits, or what happens if the sitemap already exists, so added behavioral context is modest.

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 three short sentences, front-loads the core action, and each sentence contributes useful information without repetition or 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 and annotations cover the safety profile, reducing the description's burden. However, with 0% schema description coverage, the lack of explanation for site_url and the absence of context about prerequisites or alternative tools leaves meaningful gaps for an agent invoking the tool.

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 must compensate for both parameters. It adds useful meaning for sitemap_url by requiring a complete URL and giving an example, but site_url is left entirely unexplained, so the compensation is only partial.

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 verb and resource: 'Submits/resubmits a sitemap to Google.' It clearly conveys the action, but does not differentiate itself from sibling tools like gsc_delete_sitemap or gsc_sitemaps, leaving the agent to infer the distinction from the tool name alone.

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 explicit when-to-use or when-not-to-use guidance is provided. The phrase 'Enables faster crawling of new/updated content' gives a reason to use the tool, but it does not tell the agent when this tool is preferred over alternatives or what prerequisites exist.

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