Create an analytics alert

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

The idempotentHint annotation already signals safe repeated calls, and the description adds the 'reusing an existing alert of the same type' behavior, which provides some transparency beyond the annotation. However, it does not clarify what happens to the existing alert (updated, replaced, ignored) or whether the operation is otherwise destructive.

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 one efficient sentence with no filler, and the core action is front-loaded. It loses a point because the phrase 'reusing an existing alert of the same type' is compressed to the point of ambiguity.

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?

With no output schema and only a short description, an agent is left guessing what a successful call returns, what happens when an alert of the same type exists, and whether metrics/funnels must be configured beforehand. The description only partially explains the reuse behavior.

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 schema describes projectId and the type enum, but only 33% of parameters have schema descriptions. The description adds some meaning by framing type as 'traffic or conversion', but it does not explain threshold units, threshold meaning, or how the three enum values map to alert behavior. Given the low coverage, the description does not sufficiently compensate.

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 names a specific verb and resource: it creates a traffic or conversion alert, which clearly distinguishes it from the sibling tools in this workspace (none of which are alert-specific). However, it is less explicit about whether the result is a brand-new alert or an update, which slightly weakens the 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?

The description implies that this tool is for creating alerts and mentions reuse, but it does not state when to prefer this over other tools, nor does it explain prerequisites such as needing analytics or project setup first. No alternatives or exclusions are given.

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