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

With no annotations, the description carries the behavioral burden. It does state that this is a read operation for account and quota, which implies no mutation. However, it does not disclose details like response structure, authentication needs, or any rate-limit behavior, though those may be less critical for a simple read tool.

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 short and front-loads the key instruction to use the tool first. It includes a useful API URL without excessive detail, though the Vietnamese and English sentences are partially redundant.

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 zero-parameter read tool, the description provides enough context: when to use it, what it reads, and where the API endpoint lives. It does not describe the exact return payload, but 'account and quota' gives adequate operational meaning without an output schema.

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 tool has zero parameters and the schema is fully covered, so the description need not explain parameters. The baseline of 4 applies and the description appropriately omits irrelevant parameter details.

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 reads the account and quota, and explicitly says to use it first during email integration. The verb 'read' plus the resource 'account and quota' is specific, though it does not explicitly differentiate from sibling mail tools.

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 gives clear usage context: 'Khi bắt đầu tích hợp email' (when starting email integration) and 'Use first'. It communicates when to invoke the tool but does not mention when not to use it or point to alternatives.

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