Notifications_createSubscription

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

With no annotations provided, the description carries the behavioral burden. It discloses that the operation 'Creates a subscription' and that it runs remotely in the Kuudo deployment, which is a useful behavioral trait. However, it does not mention prerequisites such as the destination already existing, whether duplicates are allowed, authentication needs, or what the response contains, leaving notable gaps for a state-changing tool.

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 and mostly information-dense, front-loading the execution location and then stating the purpose. The phrase 'Catalog entry' is filler and does not help an agent select or invoke the tool, which prevents a perfect score. Otherwise, the structure is clear and efficient.

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?

Despite the simple concept, the tool lacks an output schema, annotations, and defined parameters, so the description must carry the full invocation burden. It names conceptual inputs but does not provide enough detail for an agent to construct a valid call, such as parameter names, destination formats, or notification type values. The note about running in the Kuudo deployment is interesting but does not make the tool actionable.

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 input schema has zero defined properties, but the description adds meaning by naming the two conceptual inputs: 'specified notification type' and 'specified destination.' This is valuable given the empty schema, though it does not specify allowed formats, enums, or parameter names, so it stops short of a perfect score.

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: 'Creates a subscription for the specified notification type to be delivered to the specified destination.' This clearly separates it from sibling tools like createDestination and getSubscription. The 'Catalog entry' prefix is vague, but the core sentence is unambiguous about what the tool does.

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 implies the tool should be used when a subscription needs to be created for a notification type and destination, and it adds the context that it runs in the Kuudo deployment. However, it does not explicitly mention when not to use it or point to sibling alternatives such as Notifications_createDestination. Usage guidance is implied rather than explicit.

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