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

With no annotations, the description carries the full burden. It discloses credit consumption condition and scopes the analysis to netlinking platforms. It does not mention side effects or return format, but for a read-like analysis, the disclosure is adequate.

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 three sentences plus an argument line. It is front-loaded with the purpose, then cost, then param. No superfluous words, every sentence serves a purpose.

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 description covers purpose, cost, and argument, but lacks any indication of the output format (e.g., list of domains, counts). Given no output schema, the agent would benefit from knowing what to expect. Still, for a simple parameter, it is reasonably complete.

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?

The single parameter 'competitor' is described with its meaning ('Competitor domain') and an example ('competitor.com'), adding significant value over the schema which only has type and title. With 0% schema coverage, the description fully compensates.

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 verb 'Analyze' and the resource 'competitor's referring domains' with context 'available on netlinking platforms'. It distinguishes from siblings like 'check_domain' and 'similar_domains' which serve different purposes.

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 provides an explicit cost condition ('Costs 1 credit per request only if results found') and the argument format. However, it lacks explicit guidance on when not to use this tool versus alternatives like 'similar_domains' or 'check_domain'.

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