backlink_analysis

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful behavioral context by disclosing that it combines Serpstat backlink overview with Moz domain authority data, which indicates data provenance. However, it does not mention output format, rate limits, or any caveats about data freshness or availability.

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 concise and front-loaded: the first sentence states the core purpose and outputs, the second adds data-source context, and the Args block clarifies the required parameter. Only minor redundancy exists with the schema for the 'domain' parameter, but overall it is tightly written.

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?

Given the tool's moderate complexity (one required parameter, no output schema), the description provides adequate purpose and data-source context. It lacks details on return structure, limitations, or when to prefer other SEO tools, but for a straightforward read-only analysis tool it is minimally sufficient.

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 description carries the responsibility. It explains the 'domain' parameter with a clear example ('example.com'), which is helpful. However, the 'config' parameter is entirely undocumented in both the schema and the description, leaving the agent without guidance on its purpose or accepted values.

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 uses a specific verb ('Analyze') and a clear resource ('a domain's backlink profile'), and lists concrete metrics (referring domains, domain authority, spam score). It distinguishes itself from sibling SEO tools by focusing on backlink data and naming the combined data sources (Serpstat and Moz).

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 description states what the tool does but does not provide any guidance on when to use it versus alternatives like competitor_analysis or seo_domain_overview. There are no exclusions, prerequisites, or contextual hints about suitable scenarios, leaving the agent to infer usage from the tool name alone.

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