Domain Keywords Comparison

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

No annotations are provided, so the description must disclose behavioral traits. It states the tool is read-only (analyzes/comparses), but does not mention required permissions, rate limits, data freshness, or side effects. The description lacks depth for a complex 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?

Two sentences, efficient and front-loaded. No redundant information. Every sentence serves a purpose: first states core function, second clarifies the two comparison modes.

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 is minimal for a tool with 10 parameters and no output schema. It covers the main idea but does not elaborate on pagination, sorting, or typical use cases. The schema fills some gaps, but the description could be richer.

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 100%, so the schema already documents each parameter. The description adds overarching context (e.g., explaining diff=0 vs 1, and which domain has keywords in gap mode). This adds moderate value beyond the schema descriptions.

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 compares keyword rankings between two domains, with two modes (common keywords or gap). It uses specific verbs ('analyzes', 'compares', 'finds'). However, it does not explicitly differentiate from sibling tools like 'domainKeywordsReverseComparison', which likely does the opposite comparison.

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 implies usage for comparing two domains, but provides no explicit guidance on when to use this tool versus alternatives (e.g., domainCompetitors, domainKeywords). No 'when not to use' or prerequisite conditions are mentioned.

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