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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real behavioral context beyond that: it degrades gracefully without credentials by explaining how to connect, and it enumerates the diagnostic payload (account, plan, auth method, per-property GA4/Bing/branded-term gaps, panel URL, remediation steps).

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 purpose is front-loaded and the usage trigger follows immediately, so an agent can stop reading early. The trailing Portuguese sentence restates the same content in another language, which is redundant for an agent parsing English and slightly dilutes an otherwise dense, waste-free description.

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 carries the full burden of describing return content, and it does so thoroughly: identity/auth state, plan, property inventory, per-property coverage gaps, remediation URLs and steps. Combined with the unauthenticated path, an agent knows exactly what it will get and what to do with it.

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 tool takes no parameters, so there is nothing for the description to disambiguate. Baseline 4 applies; no parameter-level claims are made or needed.

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: reports authentication state, the Organiq account (name, plan, auth method), available Search Console properties with data coverage, and what is missing with remediation steps. That scope is unmistakably distinct from every sibling, all of which are analysis/query tools.

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?

Explicitly names the triggering conditions: when another tool returned unauthorized or site_not_found, or before a first analysis. It does not state when not to call it or name a competing alternative, but for a diagnostic entry-point tool the positive guidance is unusually concrete.

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