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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered by structured data. The description adds that this reflects an import/ingestion state, which is useful context, but says nothing about freshness, staleness, or any intermediate/in-progress status the caller must interpret.

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?

A single front-loaded sentence with no filler; the core meaning lands immediately. It is appropriately sized for a simple status lookup, though terse enough to be bordering on under-specified.

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?

The tool is simple (2 required params, no output schema, no nesting), and the description conveys the essential purpose. However, both required parameters remain unexplained and there is no hint of what statuses or states the caller should expect, leaving a gap for correct invocation.

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 0%, so the schema documents neither projectId nor siteId, and the description does not compensate—it never mentions either parameter, their formats, or how siteId relates to projectId. With a low-coverage schema the description should carry this burden and does not.

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 (Read) and resource (backlink inventory status / import state), which is distinct from act-on siblings like start_backlink_inventory or add_backlink. It does not, however, explicitly name the neighboring read tools (get_backlinks_overview, list_backlinks) to sharpen the boundary.

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?

The phrasing implies a status-polling use case for a backlink import, so an agent can infer it is called after start_backlink_inventory and before consuming results. But there is no explicit when-to-use, no mention of alternatives such as get_backlinks_overview, and no statement of prerequisites.

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