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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered structurally. The description adds meaningful behavioral context beyond annotations: monitors stop sending alerts to the deleted channel, which explains a downstream consequence. It does not mention irreversibility or required permissions, but the key consequence is disclosed.

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 two short sentences with no wasted words. The purpose is front-loaded, and the behavioral consequence follows immediately. Every sentence earns its place.

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 delete tool with annotations covering destructiveness and idempotency, the description is nearly complete. It states the action and the downstream effect on monitors. It could add a note about irreversibility or confirmation, but the essential context needed to call it correctly is present.

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 coverage is 100%, so the channel_id parameter is already fully documented in the schema. The description adds no additional meaning about format, source, or validation for channel_id. Baseline 3 is appropriate when the schema carries parameter semantics.

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 states a specific verb and resource: delete an alert channel. It is clearly distinct from delete_monitor, delete_page, and update_channel because the resource is named. It does not explicitly differentiate from other delete tools, but the resource name makes selection straightforward.

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 such as update_channel or delete_monitor. It does not mention prerequisites, confirmation requirements, or conditions under which deletion is inappropriate. The implied usage is simply 'use this to delete,' which is minimal guidance.

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