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

Adds substantial behavior beyond the annotations: rate limits (weekly free / hourly premium) and the auth flow (guest call returns 401 and kicks off OAuth). These operational details are exactly what the structured fields cannot convey and directly affect whether/how an agent invokes it.

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?

Three tight sentences: purpose first, then cadence limits, then auth. No filler, and the most decision-relevant information is front-loaded.

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?

There is no output schema, so the description is the sole source of return-value context, and it does say what facets get re-measured. It omits whether the read is synchronous or asynchronous and what the response shape is, leaving a minor gap for a mutation-triggering, non-idempotent call.

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, so the schema already documents 'domain' as the Atlas-listed domain. The description's 'claimed site' and 'pages you named' hint at the domain's relationship to the ownership claim, but add no syntax or format detail beyond the schema. Baseline 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 gives a specific verb ('Re-read the claimed site now') and enumerates exactly what is captured - activity, hiring, releases, crawler policy, identity files. It is clear what the tool does, though it does not explicitly contrast itself with close siblings like atlas_owner_verify, atlas_owner_stats, or analyze_site.

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 implies usage ('now', plus weekly/hourly cadence tied to tier) and states the auth prerequisite, but names no alternative tool and gives no when-not-to-use guidance. An agent can infer this is the forced-fresh read path, but must deduce it from siblings.

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