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

Annotations are empty, so the description bears the full burden of behavioral disclosure. It does reveal access requirements and the ownership constraint, which is useful. However, it does not describe the actual effect of disabling (e.g., whether notifications stop immediately, whether the action is reversible, idempotency, or error behavior), leaving meaningful behavioral ambiguity.

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 one concise sentence with the action and resource front-loaded, followed by the essential access prerequisite. There is no filler, repetition, or unnecessary detail.

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 single-parameter mutation with no output schema, the description provides the core action, resource ownership, and access requirements, which is sufficient for an agent to select and invoke the tool correctly. It falls short only in not describing the outcome/return shape or reversibility, but the tool's low complexity keeps this gap relatively minor.

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 has 100% description coverage for the single parameter, channel_id, described as 'The ID of the notification channel to disable.' The description only repeats 'by ID' and adds no new information about the parameter's format, origin, or constraints, so it does not enhance 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?

The description uses the specific verb 'Disable' and clearly identifies the resource as 'a notification channel owned by the current user by ID.' This distinguishes it from enable-notification-channel, delete-notification-channel, and test-notification-channel, making the tool's exact scope unambiguous.

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 mentions important prerequisites: Full Access MCP token and an eligible paid plan. However, it does not explicitly explain when to choose this tool over enable-notification-channel, delete-notification-channel, or test-notification-channel. The usage context is mostly implied by the action verb and sibling tool names rather than stated directly.

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