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

The readOnlyHint annotation covers safety, and the description adds meaningful behavioral context: it examines data from the last day, works per environment, and looks for specific issue categories including leaked keys and stale SDKs. It does not describe output shape, but that is less critical for a read-only diagnostic tool without an output schema.

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 dense but useful, front-loading the diagnostic scope and then the usage trigger. It could be tightened slightly, but every sentence contributes information about what is checked or when to call it.

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 simple, read-only, one-parameter diagnostic tool, the description covers purpose, scope, and usage well enough to call it correctly. The main gap is the unexplained applicationId parameter, but no output schema is present so return values need not be described here.

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 description coverage is 0%, and the description does not explain the applicationId parameter, its format, or how to obtain a valid ID. The phrase 'an application's SDKs' implies an application-scoped call, but the parameter itself is essentially undocumented outside the raw schema.

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 states a clear diagnostic resource: SDK setup problems per environment based on recent traffic. It specifies the kinds of problems detected, making the tool distinguishable in practice, but it does not explicitly contrast itself with sibling tools such as get_sdk_docs or generate_flag_types.

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?

It gives explicit when-to-use guidance: when flags aren't behaving as expected, and after adding flag code and running the app. It does not state when not to use the tool or name an alternative, so it falls short of full when/when-not guidance.

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