Agent Architecture
Design AI-assisted marketing workflows with clear roles, inputs, and review gates.
Key takeaways
- The architecture defines what AI agents may draft, what humans must approve, and what evidence every output cites.
- Five agent roles (research, persona, content, performance, analytics) each have a required input and a human review gate.
- Agents never invent customer evidence, metrics, or legal claims; brand voice and forbidden claims live in a shared context pack.
- High-risk channels like paid ads and pricing pages require explicit approval before launch.
- Agent value is measured by decision speed and asset quality, not raw content volume.
AI agents should increase marketing throughput without turning the brand into generic output. The architecture must define what agents can draft, what humans approve, and what evidence every output must use.
Agent Roles
| Agent | Main job | Required input | Human gate |
|---|---|---|---|
| Research agent | Summarize market, customer, and competitor signals | Source list and research question | Source quality review |
| Persona agent | Convert signals into audience hypotheses | Segment, job, pains, triggers | Strategy review |
| Content agent | Draft outlines, posts, emails, and landing copy | Brief, voice rules, proof points | Editorial approval |
| Performance agent | Suggest creative tests and budget moves | Campaign data and constraints | Spend approval |
| Analytics agent | Explain KPI movement and anomalies | Dashboard export and context | Decision review |
Workflow Pattern
Operating Rules
- Agents never invent customer evidence, case studies, metrics, or legal claims.
- Every draft includes the source, target persona, funnel stage, and intended action.
- Brand voice and forbidden claims live in a shared context pack.
- High-risk channels such as paid ads, pricing pages, and legal-sensitive claims require explicit approval.
- Agent output is measured by decision speed and asset quality, not raw content volume.
