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

Annotations already declare destructive=true and idempotent=false, and the description adds genuinely new behavioral context: deleting only stops Google reading the URL as a sitemap and does not touch the file or deindex anything. The confirm=false preview mode is also disclosed, which annotations do not cover.

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?

Front-loads the action, then the rationale, then the constraints. The background narrative ('Submitting was possible, removing was not...') is slightly verbose but earns its place by justifying the tool's existence and preventing misuse.

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 3-parameter destructive tool with an output schema present, the description covers purpose, safety semantics, dry-run behavior, and input format. Nothing an agent needs to invoke it 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 coverage is 0%, so the description must compensate and largely does: sitemap_url must be the complete URL exactly as gsc_sitemaps lists it, and confirm=false previews the operation. site_url is left unexplained, but its meaning is self-evident from the Google Search Console context.

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 and resource ('Removes a submitted sitemap from Search Console') and clearly distinguishes itself from the sibling gsc_sitemaps/gsc_submit_sitemap operations. An agent can tell immediately that this is the removal counterpart to submission.

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 concrete when-to-use context: stale or wrongly submitted entries, a page accidentally submitted as a sitemap, an orphaned sitemap_index.xml. It also routes the agent to gsc_sitemaps for the exact URL. It doesn't state explicit when-NOT-to-use conditions, but the scope is clear.

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