Gửi thử thông báo email

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

The annotations indicate this is not a read-only operation (readOnlyHint: false) and is not idempotent (idempotentHint: false), which the description aligns with by saying 'Send'. It also clarifies that the email goes only to 'verified recipients' and is a test message, adding useful context. However, it does not disclose potential side effects like rate limits or what happens if the config is invalid.

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, front-loaded sentence that efficiently conveys the action and scope. Every part of the sentence earns its place with no redundancy.

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 tool with one parameter, no output schema, and annotations covering safety profile, the description is adequate but incomplete. It lacks details on error handling, recipient verification status implications, or comparison with similar testing tools, which would help an agent use it correctly in context.

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 fully documents the single parameter 'config_id' with a UUID description, so the baseline is 3. The description does not add any further meaning about this parameter, but it also does not need to since the schema coverage is 100%.

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 a specific verb ('Send a test notification') and resource ('email'/'verified recipients'), making the action understandable. However, it does not explicitly differentiate itself from its likely sibling tool (monapay_test_zalo_group) or clarify its relation to other email config 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 provides no guidance on when or why to use this tool versus alternatives like monapay_test_zalo_group or mail_webhook_test. There is no mention of prerequisites or contexts for usage, leaving the agent to infer.

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