get_channel_info

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get information,' implying a read operation, but does not state whether auth is required, rate limits apply, or what side effects (none expected) occur. It does not even mention that the call is read-only explicitly.

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 single, front-loaded sentence with no wasted words. However, it is under-specified to the point of being only barely more informative than the tool name, so the conciseness is not effectively serving the agent.

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?

Even though an output schema exists, the description is too thin for a tool that likely depends on OAuth (given siblings like get_youtube_token_status) and a channel identifier. It does not mention prerequisites, how to find the channel_id, or any constraints, leaving the agent under-informed for a correct invocation.

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?

The schema has zero description coverage for channel_id, and the description adds no parameter meaning. It does not explain what channel_id should be (e.g., a YouTube channel ID vs. handle), how to obtain it, or any expected format. With 0% coverage, the description was expected to compensate but does not.

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 uses a specific verb ('Get') and resource ('YouTube channel'), clearly stating the tool's function. However, it does not explicitly distinguish it from sibling tools like get_video_details or get_youtube_subscriptions, though the resource type is inherently distinct.

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?

There is no guidance on when to use this tool versus alternatives, no mention of prerequisites such as OAuth authentication, and no indication of what situations call for this compared to other 'get_*' tools. The agent must guess when to invoke it.

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