indexing_get_metadata

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

No annotations are present, so the description must fully disclose behavior. It states the tool 'checks' metadata, implying read-only, but doesn't confirm idempotency, rate limits, or authentication requirements. The return format is also not described, leaving uncertainty about what the agent receives.

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 a single, well-formed sentence with no unnecessary words. It is front-loaded with the action and resource, making it easy to parse quickly. Ideal conciseness for a simple tool.

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?

Given the tool's simplicity (one parameter, no nested objects, no output schema) and the lack of annotations, the description is minimally adequate. It explains the primary action but omits behavioral details like response format and whether the call is safe. It could be more complete without sacrificing conciseness.

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 100% with one parameter 'url' described as 'Fully-qualified URL to check.' The description rephrases this but adds no new semantic info (e.g., requires http/https, what constitutes 'latest', or handling of malformed URLs). Per guidelines, baseline is 3 when coverage is high, and the description does not exceed that baseline.

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 uses a specific verb 'Check' and identifies a clear resource: 'latest Indexing API update/remove notification metadata for a URL.' This distinguishes it from sibling tools like 'indexing_publish_url' and 'inspect_url'. However, the jargon 'Indexing API update/remove notification metadata' may not be immediately clear to all users, slightly reducing clarity.

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 guidance is provided on when to use this tool versus alternatives, or any prerequisites. Sibling tools include 'indexing_publish_url', 'indexing_batch_publish', and 'inspect_url', but the description gives no context for differentiating use cases.

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