The Agentic Periodic Table

Raw sequential computation. CPU and RAM at the sub-atomic level. The substrate of all computation inside an agent.

P1 Infrastructure. Provides the computational and connectivity substrate required before any higher-order agentic behavior can function.

Unstructured persistent storage. Bytes, files, and artifacts that survive process boundaries. Imposes no schema.

P1 Infrastructure. Provides the computational and connectivity substrate required before any higher-order agentic behavior can function.

Schema-governed, queryable, transactional storage. Enables precise retrieval, joins, and transactional integrity.

P1 Infrastructure. Provides the computational and connectivity substrate required before any higher-order agentic behavior can function.

Network connectivity to APIs, queues, webhooks. The boundary between internal computation and the outside world.

P1 Infrastructure. Provides the computational and connectivity substrate required before any higher-order agentic behavior can function.

Transient data during active processing: intermediate outputs, current tool results, and active reasoning context.

P2 Context. Captures live operational context during execution and keeps a running system coherent across steps.

Position and control flow across multi-step processes. Carries a double bond in plan-and-execute compositions.

P2 Context. Captures live operational context during execution and keeps a running system coherent across steps.

Serialized snapshots of execution enabling pause, resume, replay, and recovery.

P2 Context. Captures live operational context during execution and keeps a running system coherent across steps.

Accumulated context of an active interaction: dialogue history, recent exchanges, and active preferences.

P3 Short-Horizon Retention. Holds information across time, from active session context to durable long-horizon memory.

Temporary task-specific artifacts during active execution. Task-scoped scratch space for intermediate results.

P3 Short-Horizon Retention. Holds information across time, from active session context to durable long-horizon memory.

Generates and interprets meaning. The cognitive substrate of every agent. The only element that reasons.

P4 Semantic Processing. Generates or encodes meaning and defines the semantic core of the framework.

Encodes content into dense vector representations. Does not reason; it represents. Load-bearing in all RAG agents.

P4 Semantic Processing. Generates or encodes meaning and defines the semantic core of the framework.

Durable world knowledge as semantic vectors. Requires Ec to populate and Lm to query. The substrate of RAG pipelines.

P5 Long-Horizon Retention and Action. Holds information across time, from active session context to durable long-horizon memory.

Durable knowledge of how work should be performed: playbooks, rulebooks, SOPs, and multi-step protocols.

P5 Long-Horizon Retention and Action. Holds information across time, from active session context to durable long-horizon memory.

Records of prior executions, feedback signals, and corrections generated by the collision of traces with correction signals.

P5 Long-Horizon Retention and Action. Holds information across time, from active session context to durable long-horizon memory.

Observational access to external state. Retrieves information without mutating it.

P5 Long-Horizon Retention and Action. Directs cognition toward effect in the world through observation, mutation, computation, or communication.

Mutational access to external state. Performs actions that change something in the world outside the agent.

P5 Long-Horizon Retention and Action. Directs cognition toward effect in the world through observation, mutation, computation, or communication.

Deterministic computation and transformation. Executes code and performs mathematical operations.

P5 Long-Horizon Retention and Action. Directs cognition toward effect in the world through observation, mutation, computation, or communication.

Emits information outward to humans or systems. Directed at an interpreter rather than a storage target.

P5 Long-Horizon Retention and Action. Directs cognition toward effect in the world through observation, mutation, computation, or communication.

Extracting, identifying, labeling, and classifying. Structures Lm output when the task is to identify what something is.

P6 Reasoning Patterns. Structures how cognition operates without directly acting on the world.

Condensing, reorganizing, and normalizing. Changes the form of content without changing its substance.

P6 Reasoning Patterns. Structures how cognition operates without directly acting on the world.

Producing new artifacts, language, and code. Structures Lm output when the task is to create something new.

P6 Reasoning Patterns. Structures how cognition operates without directly acting on the world.

Routing, evaluating, and prioritizing. Structures Lm output when the task is to choose between options.

P6 Reasoning Patterns. Structures how cognition operates without directly acting on the world.

Predicted gap. Real-time engagement adapting dynamically within a live exchange, distinct from Generation Skill.

P6 Reasoning Patterns. Marks a structurally expected element whose behavior is visible in practice but not yet fully formalized.

Logical protocol surface for inter-agent delegation. Carries task, intent, and authority together.

P4 Semantic Processing. Mediates protocol-level interaction between molecules, tools, and humans.

Closes the intent chain. Delivers legible output to the human whose intent initiated execution.

P6 Reasoning Patterns. Mediates protocol-level interaction between molecules, tools, and humans.

Logical protocol surface for tool discovery and invocation. Carries data and execution, not intent or authority.

P2 Context. Mediates protocol-level interaction between molecules, tools, and humans.
