youtube.niche.find

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

No annotations are provided, so the description must fully disclose behavior. It mentions using 'search demand and competition proxies' but does not explain what these mean, how ranking works, or any side effects, authentication needs, or rate limits. The description lacks behavioral depth.

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 concise single sentence with no unnecessary words. It is efficiently structured but could benefit from additional sentences to cover key details without becoming 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 no output schema and three parameters, the description is incomplete. It does not describe the output format, ranking criteria, or how to interpret results. The tool's complexity is moderate, and the description leaves many unknowns for the AI agent.

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%, so the description must add meaning beyond the schema. It implies the 'seedTopics' parameter but does not explain 'maxResults' or 'regionCode'. No parameter descriptions are given, leaving the agent to infer usage from names alone.

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 'rank' and resource 'niche opportunities', and specifies inputs as 'seed topics' and method 'using search demand and competition proxies'. It distinguishes itself from sibling tools like youtube.video.search or youtube.channel.get_profile by focusing on niche opportunity ranking.

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 on when to use this tool versus alternatives. Does not specify prerequisites, when not to use, or mention sibling tools for similar tasks. The description only states what it does.

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