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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine value by disclosing the null-tracker case, but says nothing about permissions, error behavior, or freshness of the check time beyond the stat list.

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?

Two tight sentences, front-loaded with the primary behavior and finishing with the important null edge case. Minimal waste, though the stat enumeration is somewhat redundant with the output schema.

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?

Because an output schema exists, the return-value detail is not strictly needed, and the description instead omits the more valuable missing piece: how this differs from get_indexing_tracker_report. Adequate for a simple single-parameter read tool, but with a clear routing gap.

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?

Only one parameter (siteUrl) and the schema description coverage is 0%, so the description carries some burden. It implies the tool is property-scoped via 'for a property', which loosely maps to siteUrl, but adds no format or validation guidance beyond the schema's minLength constraint.

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 (returns the Indexing Tracker config plus summary stats) and even enumerates the stat categories, so the agent knows exactly what comes back. It does not, however, distinguish itself from the close sibling get_indexing_tracker_report, leaving the agent to guess which to call.

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?

There is no when-to-use guidance and no mention of the obvious alternative get_indexing_tracker_report (or list_tracked_urls for URL-level data). The only usage hint is implicit in the null-return note.

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