analyze_community_posts

Generate high-engagement YouTube Community Tab polls, quizzes, and discussions for any niche. Use algorithm insights to reach non-subscribers and achieve growth, validation, or loyalty goals.

Instructions

Generate high-engagement Community Tab polls, quizzes, and discussion posts.

Leverages YouTube's Community Tab algorithm, which distributes polls into the home feeds of non-subscribers, creating viral discovery for new channels between video releases.

Args: niche_or_channel: Topic, niche, or creator handle (e.g. 'python programming', 'personal finance'). target_goal: Goal for the community strategy ('growth', 'video_validation', 'audience_loyalty').

Behavior2/5

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. It adds useful context about YouTube's algorithm distributing polls to non-subscribers, but it does not disclose whether the tool actually publishes posts or only generates drafts, nor does it mention authorization, rate limits, or side effects.

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

Conciseness4/5

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

The description is compact and front-loaded with the core purpose, then provides algorithm context, then documents arguments. No unnecessary filler, though the algorithm explanation could be condensed without losing value.

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?

An output schema is present, so return-value details are not the description's responsibility. However, with many sibling tools, the description provides limited decision guidance for when to choose this over alternatives, and it leaves ambiguity around publishing vs. draft generation.

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

Parameters4/5

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

Schema description coverage is 0%, so the description must define the parameters itself. It does this well with concrete examples for niche_or_channel and enumerates accepted values for target_goal, adding meaning beyond the bare schema properties.

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

Purpose4/5

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

The description clearly states a specific action ('Generate high-engagement Community Tab polls, quizzes, and discussion posts') and identifies the target resource (YouTube Community Tab). It is distinguishable from sibling tools that analyze sentiment or generate other content types, though the tool name 'analyze_community_posts' is somewhat inconsistent with the 'generate' action.

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 implies when to use it by mentioning viral discovery for new channels 'between video releases' and by offering target_goal options like growth and audience loyalty. However, it never explicitly says when NOT to use it or names alternative tools for similar community-analysis tasks.

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