Get Automation

get-automation

Inspect email automation workflows by retrieving full details of a specific automation or listing all automations with optional status filters and pagination.

Instructions

Purpose: Get details of a specific automation (with its workflow) or list all automations.

Modes:

  • With id: Returns full automation details including the workflow definition.

  • Without id: Lists all automations with optional status filter and pagination.

When to use:

  • User asks "show me my automations" or "what automations do I have?"

  • User wants to inspect a specific automation's workflow

  • Before update-automation, to see the current workflow

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault

beforeNoCursor for backward pagination (for list mode).
statusNoFilter by status (for list mode only).
Behavior4/5

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

No annotations provided, so description carries full burden. Explains dual behavior (single vs list), pagination, and status filter. Lacks mention of read-only nature but name implies it.

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

Conciseness5/5

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

Well-structured with headers (Purpose, Modes, When to use). Concise, no fluff, front-loaded. Uses bullet-like formatting for readability.

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

Completeness4/5

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

No output schema, but description mentions 'full automation details including the workflow definition' which is adequate. Lacks explicit return structure, but sufficient for selection.

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

Parameters5/5

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

100% schema coverage, but description adds value: id can be URL or ID, explains which params apply to list mode, and clarifies behavior without id.

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

Purpose5/5

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

Explicitly states the purpose: get details of a specific automation (with workflow) or list all automations. Clearly distinguishes between two modes and from sibling get-automation-runs.

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

Usage Guidelines5/5

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

Provides explicit 'When to use:' section with concrete scenarios: user asks about automations, inspect workflow, before update-automation. Effectively guides the agent.

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