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

With no annotations, the description bears full responsibility for behavioral disclosure. It does not mention side effects, read-only nature, authorization needs, or rate limits. The only implied trait is that it's a summary, likely non-destructive, but this is insufficient.

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 concise sentence that covers the main purpose. It could be improved with structured bullet points or a clearer separation of inputs and outputs, but it is not verbose.

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 has 9 parameters and no annotations or output schema, the description is insufficiently complete. It does not explain the output format, the meaning of advanced parameters, or provide examples, which is necessary 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 coverage is 0%, so the description should compensate. It only explains the 'target' parameter by mentioning domain, subdomain, or URL. The other 8 parameters (e.g., sync, rank_scale, dofollow_only) are not described, leaving their meaning unclear.

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 clearly states the tool summarizes backlink-related metrics like authority, referring domains, spam risk, broken backlinks, and actions. The verb 'summarize' and the resource 'backlinks' are specific, and it is distinguishable from sibling tools like agentseo_backlinks_list, though not explicitly differentiated.

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 guidance is provided on when to use this tool versus alternatives such as agentseo_backlinks_competitors or agentseo_backlinks_anchors. The description only states what it does, not the context of usage.

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