TDQS

A3.5/5.0
Behavior3/5

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

No annotations are present, so the description carries the full behavioral burden. It discloses verified-domain requirements, sandbox side effects, and the onboarding address limitation. However, it does not mention real-send costs/quota, idempotency behavior, template versus subject requirements, or how suppression lists affect delivery.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loads the most critical constraint: verified domain usage. The bilingual repetition is somewhat redundant but serves a mixed-language audience, and there is no filler or excessive detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 12 parameters, no annotations, and no output schema, a two-sentence description is insufficient. It omits the subject/template selection rule, retry semantics, quota/cost behavior for real sends, and what a successful response means. An agent would need to inspect the schema and infer significant behavior before invoking this side-effecting tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 25%, and the tool description adds useful meaning for sandbox behavior and the from-address requirement. It does not compensate for the many undocumented parameters such as template_id, variables, reply_to, tags, idempotency_key, and unsubscribe_url, leaving important invocation details to inference.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action: sending transactional email, and it mentions concrete use cases: OTP or notifications and sandbox testing. It does not explicitly contrast itself with sibling tools like mail_template_create or mail_suppressions_list, but the send/test framing is distinct enough.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear usage context: use a verified domain, sandbox for zero-charge tests without Internet delivery, and a special restriction on the onboarding@monamail.vn address. It does not name sibling alternatives or state when not to use this tool, so it falls short of a 5.

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