Create a notification channel

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

The description adds no behavioral detail beyond the annotations. Annotations already indicate this is a mutating, non-idempotent, non-destructive operation, but nothing is said about side effects, duplicate channel behavior, validation rules, or what the API returns after creation.

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 short, but brevity is under-specification, not effectiveness. The single sentence merely repeats the tool's title and provides no behavioral, usage, parameter, or alternative guidance.

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 creation tool with nested config, an enum type, and no output schema, this description is severely incomplete. The agent is left to infer outcomes, error cases, idempotency implications, and return values entirely from schema and tool name.

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 only 25%, and the tool description contributes nothing about the parameters. The schema's config property does explain type-specific shapes, but that is structured-schema value, not description value; the tool description itself must compensate for the other undocumented parameters and does not.

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?

Tautological: description restates name/title.

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 choose this tool over other notification-channel operations such as updating a channel, listing channels, or sending a test notification. The word 'create' weakly implies use for creation, but no context, prerequisites, or alternatives are provided.

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