start_automation_email

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

The description discloses that the tool resumes sending and is thus a mutation (consistent with annotations). It does not elaborate on side effects, idempotency, or what happens if the email is already running. The annotations already indicate non-read-only and non-destructive, so the description adds moderate value.

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 fairly concise, with a clear purpose statement followed by parameter and return details. Minor improvement could be merging the 'Args' section into prose, but overall it is well-structured and front-loaded.

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?

Given the tool's simplicity (3 parameters, no nested objects), the description covers the main action and required parameters. It mentions a JSON confirmation return but lacks details on error conditions or prerequisites. For a resume action, it is adequate but not comprehensive.

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 description provides basic explanations for the two required parameters 'workflow_id' and 'workflow_email_id', which is helpful since the schema has no descriptions. However, the optional 'account' parameter is left undocumented, and the schema coverage is 0%, so the description should compensate more fully.

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 the verb 'start' and the resource 'automation email', specifying that it resumes a previously paused email in a classic automation workflow. It distinguishes itself from siblings like 'start_automation' and 'pause_automation_email' by focusing on a single email rather than the entire workflow.

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 explains that the tool is used to resume a paused automation email, providing context on when to use it. However, it does not explicitly mention when not to use it or offer alternatives, such as using 'start_automation' for the entire workflow.

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