AI Search Comparison & Leaderboard (SE Ranking)

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states that it 'Returns brand presence, link presence, share of voice rankings, and leaderboard' but does not disclose potential side effects, authorization requirements, rate limits, or whether it is read-only. Given the absence of annotations, more behavioral detail is needed.

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 consists of two concise sentences that front-load the tool's primary function and outputs. Every sentence adds value, with no redundancy or filler.

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 (5 parameters with nested objects, no output schema, and a unique AI focus among siblings), the description adequately covers what the tool does and the kind of data it returns. It does not include return format details, but the absence of an output schema means the agent must rely on the description. The description could be slightly more complete regarding the exact data structure.

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%, meaning the input schema already provides detailed descriptions for all 5 parameters. The description does not add significant value beyond the schema for parameters; it merely rephrases the purpose. Hence a baseline score of 3 is appropriate.

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's purpose: 'Compare multiple domains/brands in AI search engines'. It specifies the resources (ChatGPT, Perplexity, Gemini, AI Overview, AI Mode) and the outputs (brand presence, link presence, share of voice rankings, leaderboard). This distinguishes it from sibling tools that focus on audits, backlinks, or keywords.

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 explicitly states the usage context: 'Use this for AI search comparison, competitor analysis, and visibility benchmarking.' This helps the agent determine when to invoke this tool. However, it does not mention when not to use it or suggest alternative tools.

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