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

Annotations already declare readOnlyHint=true, openWorldHint=false, destructiveHint=false, so safety is covered. The description adds that results carry status and latest-check information, which is modestly useful, but says nothing about pagination, filtering behavior, or result volume for a 15-parameter query tool.

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 tight sentence with the resource and scope front-loaded and no filler. It is concise, though arguably too terse for a 15-parameter tool.

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?

Fifteen parameters at 0% description coverage, no output schema, and no annotation gaps filled by the text leaves an agent without enough to call this query tool precisely. The definition is incomplete for the tool's complexity.

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% across 15 parameters. The description names none of them, so filters like statuses, dofollow, pricingModes, categories, traffic/domain-rating ranges, and sortBy are only inferable from enum values. It fails to compensate for the coverage gap.

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 (List), resource (backlinks), and scope (those Ranklybee tracks for a website), plus a hint at returned fields (status, latest check). It is clear, but it does not differentiate itself from closely related siblings like list_featured_backlinks or get_backlinks_overview.

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 and no alternatives named, despite several overlapping siblings (list_featured_backlinks, get_backlinks_overview, check_site_backlinks). An agent must guess which listing tool fits a given intent.

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