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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety and scope are covered. The description adds a useful conditional note that impressions and clicks are only returned when Search Console or Bing is connected, which is real behavioral context beyond the annotations. It does not, however, discuss pagination behavior or default date handling.

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, front-loaded sentence that packs the relevant output fields without wasted words. The noun-phrase structure is slightly less clear than a full declarative sentence, but it is efficient and appropriately sized.

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 read-only retrieval tool with no output schema, the description enumerates the primary return fields and notes the conditional availability of impression/click data. This gives the agent enough to understand what comes back, though it omits pagination behavior and any hint about sorting or result ordering.

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 description coverage is 100%, so each of the five parameters is fully documented in the input schema. The description adds no additional meaning about the date range, brand selection, or pagination parameters, leaving the baseline score of 3 appropriate.

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 specifies the resource (articles written for the brand) and the key data fields returned (status, GEO score, published URL, indexing status, impressions, clicks), making the tool's function clear. However, it is a noun phrase without an explicit verb like 'retrieves' or 'lists', and it does not differentiate itself from the sibling list_articles, so it stops short of a 5.

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 when-to-use guidance is provided. The description never mentions when this tool should be chosen over list_articles, get_visibility, or other siblings, nor does it note any prerequisites or exclusions. The agent is left to infer usage entirely from the tool name and data fields.

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