get_email

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

With no annotations provided, the description carries the burden of behavioral disclosure. It usefully states that the response includes subject, body, and thread, and 'Get' implies a read-only operation. It does not mention edge-case behavior such as not-found handling, authentication requirements, or whether the email is marked as read, but for a simple read tool this is a moderate gap.

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 with no filler. Every word contributes meaning by identifying the action, target, and returned content.

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 one-parameter read tool with no output schema, the description provides the essential information: what object is retrieved and what parts of it are returned. It does not cover error behavior or alternative usage, but those are minor for this simple tool and the description otherwise allows correct invocation.

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 has a single required parameter, email_id, with no description and 0% schema description coverage. The tool description does not elaborate on this parameter beyond naming the resource, so the description adds little semantic value. The parameter name and tool name make the meaning inferable, but the description does not compensate for the missing schema documentation.

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 uses a specific verb ('Get'), a specific resource ('one email'), and defines the content scope ('full subject/body/thread'). This clearly distinguishes it from list-oriented siblings like list_emails and from action-oriented siblings like reply_to_email or forward_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?

The intended use is implied by the singular 'one email' and the mention of full content: an agent can reasonably infer this tool is for retrieving a single email's details rather than listing or acting on emails. However, there is no explicit guidance about when to prefer this over list_emails or search_leads_by_email, nor any stated exclusions.

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