create_event_subscription

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

No annotations are present, so the description carries all burden for behavioral disclosure. It implies a write operation but does not state side effects, required permissions, rate limits, or whether the subscription is active immediately. This leaves significant 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 very short at six words, which is concise but at the expense of substance. It front-loads the action and resource, but the brevity results in under-specification, making the tool harder to use correctly.

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?

Given the nested object parameter, no output schema, and no annotations, the description fails to provide near-zero contextual completeness. The agent cannot infer proper usage, data format, or expected results from this definition alone.

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 single parameter 'subscription_data' is an object with no description in the input schema (0% coverage). The tool description does not explain its structure, required fields, or purpose beyond the name. The agent has no guidance on how to construct this data.

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 'Create a new event subscription' clearly indicates the action and resource, but it does not provide any additional context to distinguish this tool from other create tools in the sibling list, such as create_bot or create_chart. The lack of specificity about what an event subscription is limits clarity.

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?

No guidance is provided on when to use this tool versus alternatives like update_event_subscription or test_event_destination. The description does not mention prerequisites, intended scenarios, or exclusions, leaving the agent without decision support.

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