trigger-app-event

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states 'trigger an app-defined event' without any details on side effects, required permissions, system state changes, or return behavior. This is insufficient for understanding the tool's impact.

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 sentence, which is concise and easy to read. However, it is so minimal that it approaches under-specification. Every word earns its place, but more informative content would be beneficial.

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 tool has 23 parameters, no output schema, and a complex function of triggering app events, the description is incomplete. It does not explain what constitutes an 'app-defined event', how to structure the payload, or what the response contains. This is insufficient for an agent to confidently use the tool.

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 91%, meaning most parameters are documented in the input schema. The description adds no extra meaning beyond what is already in the schema. The required 'event' parameter and optional 'payload' are not explained further in the description, so baseline 3 is appropriate.

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 verb 'trigger' and the resource 'app-defined event'. However, it does not differentiate from sibling tools like 'alert' or 'click' which also trigger actions. The purpose is clear but lacks specificity that distinguishes it.

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. The description does not specify the context, prerequisites, or any scenario where this tool is appropriate compared to sibling tools like 'open' or 'press'.

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