Agentic Periodic Table
35 design patterns. Two axes. One map.
Every agentic system is built from composable primitives. This table organises 35 patterns along two axes — function (what job the pattern does) and autonomy level (how much human oversight it requires) — so you can read a pattern's properties from its position, not just its name.
X-axis — Function (7 groups)
- Perception
- Reasoning
- Memory
- Action
- Coordination
- Evaluation
- Governance
Y-axis — Autonomy level (5 periods)
- P1 Directed — Human writes every step
- P2 Guided — Human sets goal, agent plans
- P3 Supervised — Agent runs, human reviews output
- P4 Monitored — Agent runs, human watches for anomalies
- P5 Autonomous — Agent self-directs and self-corrects

How to read this table
Position predicts properties
Top-left cells are the safest, most human-controlled primitives. Bottom-right cells are the most autonomous and hardest to govern. Reading diagonally tells you how risk scales.
Same row — same trust level
Patterns in the same period operate at the same autonomy level. They compose naturally with one another — a P2 reasoning pattern pairs well with a P2 memory pattern.
Same column — same job
Patterns in the same group do the same functional job at different autonomy levels. You can swap a P1 pattern for a P3 one as you scale up trust in the system.
Molecules are real systems
Any real agent product is a molecule: a combination of patterns across groups and periods. A coding agent, for instance, is typically P3/Rsn + P3/Act + P2/Evl working in concert.
The table is a statement
Unlike the physical periodic table, this one reflects a proposed taxonomy. Positions encode opinion — and they invite debate. Use it as a thinking tool, not a fixed truth.
