findConsistentOutlierChannels

Read-onlyIdempotent

Discover emerging YouTube channels consistently outperforming their peers in any topic. Specify niche, channel age, and consistency level to find high-potential outliers.

Instructions

A powerful, high-cost discovery tool. It finds emerging channels that show consistent, high-performance relative to their size within a specific topic and timeframe.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
queryYesRequired. The core topic or niche to investigate (e.g., 'stoic philosophy', 'AI history explainers').
channelAgeNoOptional. Filters by channel age. Default: 'NEW'. 'NEW' = under 6 months (emerging), 'ESTABLISHED' = 6-24 months (proven).NEW
consistencyLevelNoOptional. Minimum required consistency. Default: 'MODERATE'. 'MODERATE' (~30%) for broad discovery. 'HIGH' (~50%) for exceptional channels.MODERATE
outlierMagnitudeNoOptional. Required 'viral factor' for videos. Default: 'STANDARD'. 'STANDARD' (views>subs) for regular content. 'STRONG' (views>3x subs) for viral channels.STANDARD
videoCategoryIdNoOptional. YouTube video category ID to narrow search (e.g., '27' for Education). Improves relevance.
regionCodeNoOptional. ISO 2-letter country code (e.g., 'US', 'DE') to target a regional audience.
maxResultsNoOptional. Max number of channels to return. Default: 10.
Behavior3/5

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

Annotations indicate read-only and idempotent, which the description does not contradict. The description adds 'high-cost' as a behavioral trait, but without explaining what that entails (e.g., rate limits, compute). No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no fluff, front-loaded with cost warning. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 7 parameters and no output schema, the description is brief. It explains the core function but does not mention return format or any edge cases. Lacks detail on how the 'consistency' or 'outlier magnitude' manifest in output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents all parameters. The description does not add further meaning beyond restating that the tool works on a topic and timeframe. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool finds emerging channels with consistent high performance relative to size within a topic and timeframe. It distinguishes from sibling tools like searchVideos which search for videos, not channels.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description notes it is 'high-cost', implying cautious use, but does not explicitly state when to use this tool vs alternatives like searchVideos or getChannelStatistics. No exclusions or clear context for when not to use.

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