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

No annotations are provided, so the description must carry the full burden. It does not disclose whether the tool is read-only, what side effects exist, or how results are returned. The mention of 'classify' suggests data processing but no behavioral traits like rate limits or data freshness.

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 sentence, which is concise but lacks structure. It front-loads the purpose but omits needed details like parameter usage, output format, or when to apply. It is not verbose, but it sacrifices completeness for brevity.

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 complexity (16 params, no output schema, no annotations), the description is severely incomplete. It does not explain what the returned data looks like, how pagination works, or any usage constraints. A tool with this many parameters requires a much richer description.

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% and the description adds no parameter-level details. With 16 parameters (including enums and constraints), the agent receives zero guidance on what params like 'dofollow_only' or 'backlinks_status_type' mean or how to use them effectively.

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 analyzes referring domains and classifies patterns like authority recovery and outreach. It names a specific verb 'analyze' and resource 'referring domains', and mentions distinct use cases that help differentiate from sibling tools like agentseo_backlinks_list or agentseo_backlinks_summary.

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 explicit guidance on when to use this tool vs alternatives. The description implies it's for analyzing domain patterns, but does not specify when not to use it or mention other tools for specific tasks (e.g., agentseo_backlinks_anchors for anchor analysis).

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