Check setup health in one command

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

With no annotations, the description must fully disclose behavior. It only states it 'verifies' and 'suggests next action', but does not explain what happens on success/failure, whether any modifications occur, or any side effects. Lacks transparency about the nature of the check and output.

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 concise sentence, but it sacrifices completeness for brevity. While it front-loads the purpose, it omits parameter details and behavioral context, which are essential for correct usage.

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 no output schema, two undocumented parameters, and no annotations, the description fails to provide sufficient context. It does not explain the return format, how to interpret results, or the role of parameters, leaving significant gaps for a complete understanding.

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%, yet the description does not explain the two parameters 'accountAlias' and 'chatScope' at all. An agent has no information on how these affect the diagnostics, making parameter usage unclear.

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 title and description clearly state the tool performs a health check on specific components (credentials path, accounts storage, reminders store, active account binding) and suggests next action. This is a specific verb-resource combination, but it does not differentiate itself from sibling tools like 'multi_gmail_diagnostics' or 'status'.

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 on when to use this tool versus alternatives such as 'status' or 'multi_gmail_diagnostics'. No prerequisites, exclusions, or context for appropriate usage are provided.

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