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

Since no annotations are provided, the description was expected to carry the burden of behavioral disclosure. However, it only mentions billing per call and does not describe side effects, authentication requirements, or what data is returned, leaving the agent without essential transparency.

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 short but under-specified rather than concise. 'Channel Details Group: Channel' is nearly meaningless without context, and the billing note is the only concrete information. It does not front-load helpful content that aids tool selection or invocation.

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 lack of an output schema, existing annotations, and a minimal description, the tool is severely underdocumented. An agent cannot discern the return format, error conditions, or even the basic purpose, making correct usage near impossible.

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 only 33% (only 'id' has a description), yet the main description adds no explanation for 'gl' or 'hl' parameters. It fails to compensate for the sparse schema, providing zero additional semantic context for 2 of 3 parameters.

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 'Channel Details Group: Channel' is vague and essentially restates the tool name and title without specifying a verb or resource. It fails to distinguish this from siblings like get_v1_channel_channels or get_v1_channel_community, leaving the agent unsure what 'details' includes.

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 is given on when to use this tool versus alternatives. There is no mention of prerequisites, typical use cases, or exclusion criteria, making it impossible for an agent to know if this is the right endpoint.

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