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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool sends email but fails to explain critical behavioral traits: how it operates with zero parameters (does it open a draft window? use conversation context?), whether it triggers immediate sending, or any authentication/permission requirements.

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 extremely brief at three words with no filler. While efficient, it borders on under-specification rather than optimal conciseness, as it front-loads only the action without supporting context that would help an agent understand the zero-parameter behavior.

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 complex operation like sending email, the description is radically incomplete. With no output schema, no annotations, and a mysterious zero-parameter schema that contradicts typical email sending requirements (recipient, subject, body), the description fails to explain how the tool obtains necessary email content or what the execution flow entails.

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 input schema contains zero parameters. Per evaluation rules, zero-parameter tools receive a baseline score of 4. The description neither adds nor subtracts value regarding parameters since none exist to document.

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 states the basic action ('Send email') and specifies the platform ('via Outlook'), providing clear verb and resource. However, it fails to differentiate from the sibling tool 'send_email' or explain when to prefer this over other email-sending alternatives.

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 is provided on when to use this tool versus alternatives like 'send_email' or 'reply_email'. The mention of Outlook implies platform-specific usage, but explicit when-to-use or exclusion criteria are absent.

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