no_response_closure_email

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

With no annotations, the description fully covers behavioral traits: tone (calm, friendly, no guilt-tripping), length (under 80 words), and a notable effect (often gets reply). Also mentions it doesn't count against monthly draft limit. No contradictory or missing key traits for an email 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?

Extremely concise: three sentences covering purpose, benefit, and constraints. Front-loaded with the action verb and resource. Every sentence adds value, no fluff.

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 email generation tool with no output schema and complete parameter descriptions, the description adequately explains context, tone, and effect. Could mention whether the email is drafted or sent, but overall sufficient.

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?

Input schema has 100% description coverage, so baseline is 3. The description does not add new parameter-specific meaning beyond what the schema already provides, thus no extra value.

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?

Description clearly states it's for writing a 'just closing the loop' email to a prospect who has gone dark after follow-ups. It distinguishes from other email tools by emphasizing the counter-intuitive effect and tone, but could more explicitly differentiate from similar sibling tools like reactivation_email or win_back_email.

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?

Describes when to use (prospect gone dark after follow-ups) and includes a strong rationale for use. However, lacks explicit when-not-to-use guidance or alternatives among siblings.

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