Automation
Deterministic workflows: ‘when X, do Y.’ Reliable, no judgment. Examples: Zapier flows, PM tool rules.
Agent
Given a goal, it plans steps, calls tools, and acts across systems — ‘research vendors and draft a comparison.’ Powerful but needs guardrails and review.
When to use which
Assistants for drafting, automations for repeatable plumbing, agents for bounded multi-step research/ops tasks — always with human review on outputs that reach others.
