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

No annotations are provided, so the description carries the full behavioral burden. It is an external side-effecting action against Google's API with known quotas and (typically) asynchronous processing, yet the description says nothing about rate limits, partial failure, idempotency, or whether a job/status handle is returned.

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 front-loaded sentence with no redundancy — the core action is stated immediately. It is terse to the point of under-specification, but that is a completeness issue rather than wasted text.

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 mutation tool with no annotations, no output schema, and an undocumented required array parameter, the description is not complete enough. It omits return behavior (sync success vs job id), quota/rate constraints, and the failure mode for unpublished or invalid URLs.

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 only 50%: product_id is documented ('from list_products on Product Admin') but the urls array has no description of format (absolute vs relative, whether they must belong to the product's property) or cardinality limits. The description's 'published URLs' is the only hint and does not compensate for the gap on the required urls parameter.

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 ('Submit') and resource ('published URLs to Google Search Console for indexing'), which is far more informative than the bare name index_content. It does not need to differentiate from siblings since none of the listed tools (publish_content, trigger_scan, etc.) overlap directly, but it stops short of noting scope limits such as the GSC property or URL count.

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?

The phrase 'published URLs' implies a precondition (content must already be published) and gestures at the publish_content sibling, but no explicit when-to-use or when-not-to-use guidance is given. Nothing tells the agent whether to call this after publish_content, whether repeated submissions are safe, or what alternative exists for unpublished content.

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