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

With no annotations, the description must carry the full burden of behavioral disclosure. It only says the tool requests crawling and indexing; it does not mention side effects, rate limits, authentication, error behavior, or how the request outcome is reported. The note about JobPosting/BroadcastEvent is the only additional behavioral trait, but it is insufficient.

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 front-loaded with a clear purpose, but it includes a lengthy IMPORTANT section about data analysis and reporting that is tangential to the tool itself. This adds unnecessary verbosity and distracts from the tool's core behavior, making it less concise than it could be.

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 simple 2-parameter tool with no output schema and no annotations, the description covers the main function and one caveat (official schema support). However, it does not explain return values, failure modes, or any expectations after submission, leaving a moderate gap in contextual completeness.

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?

The input schema already provides complete descriptions for both parameters ('url' and 'action') with 100% coverage. The description adds minimal value beyond the schema, such as tying the action to new/updated content, but it does not introduce new syntax or clarifications, so the baseline of 3 applies.

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 clearly states the tool submits a URL to Google's Indexing API for crawling and indexing, and it distinguishes itself from siblings like submit_sitemap and submit_batch by targeting individual URL submission. It also clarifies the intended use for new or updated content.

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 description provides a clear context for use: notifying Google of new or updated content. It also includes a note about Google's official schema support versus all page types, which gives practical guidance. However, it does not explicitly mention alternatives or exclusions, so it falls short of full guidance.

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