client_unsubscribeFromChannel

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, but it only states the action without mentioning side effects, the meaning of optional parameters, idempotency, or permissions. The optional deleteLocalModels flag is completely unexplained.

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 short sentence with no fluff, but it is so minimal that it borders on under-specification. It earns its place as a concise statement but lacks informative content.

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 tool with three parameters including an optional nested object, the description is incomplete. It does not clarify why channelId is optional, what deleteLocalModels does, or the consequences of unsubscribing. The absence of an output schema further increases the need for behavioral context that is not provided.

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 provides descriptions for channelId and sessionId, covering 67% of parameters, but the description adds no parameter-level meaning. The options object with deleteLocalModels lacks any description in both schema and tool description, so the description does not compensate for this gap.

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 'Unsubscribe from channel' directly restates the tool name, adding no new information about the operation's scope or effects. It is a tautology rather than an explanatory statement.

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?

The description provides no guidance on when to use this tool versus alternatives like client_subscribeToChannel or channel_unmute. No context is given about prerequisites or the relationship to other channel-related operations.

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