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

Annotations already cover the safety profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint), so the bar is lower. The description adds genuine behavioral context beyond that: the auth precondition, the integration URL for remediation, and the multi-account resolution rule ('the property is read through the account that can see it'). It does not cover pagination or return shape, but that is a modest gap.

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?

Four sentences are efficiently used: the field list is front-loaded, followed by the auth prerequisite, the remediation URL, and the account-resolution edge case. Slightly dense but every sentence carries distinct information.

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 read-only list tool whose annotations already establish the safety profile, the description covers purpose, returned fields, prerequisites, and a tricky multi-account case. No output schema exists, but the description enumerates the key returned fields, leaving little an agent needs unresolved.

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?

There is a single parameter with 100% schema description coverage ('Property URL e.g. https://example.com'), so the schema already documents it fully. The description only implies the 'property' concept and adds no syntax or format detail beyond the schema, making the baseline 3 appropriate.

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 (List) and resource (submitted sitemaps for a property) and enumerates the returned fields: submission date, last download time, URL counts, errors/warnings. It is clear on its own but never distinguishes itself from the sibling get_sitemap, which could plausibly cover similar ground.

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?

It communicates a prerequisite (Google Search Console must be connected) and where to connect it, which is real usage context. However, it offers no explicit when-to-use guidance relative to siblings like get_sitemap or the other GSC tools, so selection is left to inference.

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