get_channel

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

Annotations already disclose that the tool is read-only, idempotent, and non-destructive. The description adds limited context by naming the inspected entity, but it does not disclose behaviors like not-found handling or the form of the returned capabilities.

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?

A single front-loaded sentence with no wasted words or repetition of schema/annotation data. It earns every word.

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?

For a simple one-parameter tool with strong annotations, the description is nearly sufficient. However, without an output schema it could more clearly define what 'mechanical metadata and capabilities' includes and how this differs from read_channel.

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?

There is one parameter and the schema already documents it as an opaque channel identifier returned by list_channels, so schema coverage is 100%. The description adds no parameter detail, but none is needed beyond the schema.

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?

States a clear verb ('inspect') and a specific resource ('mechanical metadata and capabilities') for a single terminal channel, which distinguishes it from list_channels. It does not explicitly contrast with read_channel, so it stops just short of full clarity.

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 choose this tool over read_channel or list_channels, nor any explicit when-not-to-use conditions. The intended context must be inferred from the verb and resource.

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