subscribe_alerts

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

No annotations are provided, so the description must fully disclose behavior. It covers connecting to a Socket.IO server and receiving alerts, but lacks details on connection lifecycle, how to stop (though unsubscribe_alerts exists), and whether data is returned immediately. The test mode is mentioned, but more behavioral context is needed.

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 a single clear sentence that efficiently conveys the purpose and optional features, though it could be slightly more structured.

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 subscription tool with no required parameters and no output schema, the description provides adequate context but lacks details on return format, how to unsubscribe, and error handling. It is minimally complete given the tool's complexity.

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 coverage is 100% with clear descriptions for all three parameters. The description adds minimal extra value beyond the schema, such as summarizing filtering and test mode, but does not provide new semantic information.

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 clearly states the tool's action (connect and receive) and resource (real-time emergency alerts), and includes optional filtering and test mode, distinguishing it from siblings like get_active_alerts and unsubscribe_alerts.

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 optional filtering by alert types and test mode, but does not explicitly guide when to use this subscription tool versus polling alternatives like poll_alerts or get_active_alerts.

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