mixer_link_to_channel

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only states the mode values without defining what 'replace' or 'add' actually do to existing routings. It does not mention side effects, whether previous links are removed, or how the operation affects the mixer state.

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 compact and front-loaded, stating the key action in the first sentence and mode options in the second. It contains no filler, though the terse 'mode=...' notation is slightly cryptic.

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 mutating tool with three parameters, no annotations, and no output schema, the description provides only the bare minimum. An agent can make a call, but cannot be confident about the exact behavior of the two modes or the implications for existing mixer routing.

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 0%, so the description must compensate. It partially does by clarifying that 'channel' is the channel being linked and 'track' is the mixer track, and by giving valid mode values. However, it does not explain the meaning of 'replace' versus 'add' in terms of the underlying state.

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 names a specific action ('Link a channel to a mixer track') and the resource relationship, so the basic purpose is clear. However, it does not distinguish this from closely related sibling tools such as channel_route_to_mixer or mixer_route, which likely perform similar linking/routing operations.

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 about when to use this tool versus alternative routing or mixer tools. The mode values 'replace'|'add' are mentioned, but there is no explanation of which mode to choose in a given situation or what happens if channel routing already exists.

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