Behavior2/5

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

Annotations cover basic read/write/idempotency traits, but the description adds little behavioral context beyond the endpoint and a pointer to the schema. It does not disclose side effects, such as whether creating a notification sends something, requires specific permissions, or has retry consequences. No contradiction with annotations exists, but the description carries little extra behavioral weight.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and well organized: title, endpoint, then argument notes. It avoids filler and front-loads the essential operation. The only minor issue is that 'Create Notification.' repeats the tool name, but the overall structure is efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a create operation inside a large API with many sibling create tools, this description leaves too much unspecified: what a notification is in this system, when to choose this over notification test/action variants, and what force_save actually does. The output schema exists, so return values do not need explanation, but the surrounding context is still under-specified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It identifies body as the request payload and instructs the agent to read the matching GET or /schema endpoint for the expected fields, which is genuinely useful for an opaque object. force_save is only labeled as a query parameter with no explanation of its effect, so compensation is partial.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb and resource: 'Create Notification.' and reinforces it with the endpoint. However, it does not distinguish this from closely related siblings like create_notification_action_by_name, create_notification_test, or create_notification_testall, so the purpose is clear but the differentiation is missing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 alternative notification-related create tools. The only operational advice is to read the matching GET or /schema endpoint before constructing the body, which is a prerequisite rather than usage guidance. No exclusions, alternatives, or conditions are provided.

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