Agentica Infrastructure Reference

Complete API specification for Agentica multi-agent coordination infrastructure.

When to Use

• Building multi-agent workflows with Agentica patterns
• Need exact constructor signatures for pattern classes
• Want to understand coordination database schema
• Implementing custom patterns using primitives
• Debugging agent tracking or orphan detection

Quick Reference

11 Pattern Classes

Pattern	Purpose	Key Method
Swarm	Parallel perspectives	.execute(query)
Pipeline	Sequential stages	.run(initial_state)
Hierarchical	Coordinator + specialists	.execute(task)
Jury	Voting consensus	.decide(return_type, question)
GeneratorCritic	Iterative refinement	.run(task)
CircuitBreaker	Failure fallback	.execute(query)
Adversarial	Debate + judge	.resolve(question)
ChainOfResponsibility	Route to handler	.process(query)
MapReduce	Fan out + reduce	.execute(query, chunks)
Blackboard	Shared state	.solve(query)
EventDriven	Event bus	.publish(event)

Core Infrastructure

Component	File	Purpose
CoordinationDB	coordination.py	SQLite tracking
tracked_spawn	tracked_agent.py	Agent with tracking
HandoffAtom	handoff_atom.py	Universal handoff format
BlackboardCache	blackboard.py	Hot tier communication
MemoryService	memory_service.py	Core + Archival memory
create_claude_scope	claude_scope.py	Scope with file ops

Primitives

Primitive	Purpose
Consensus	Voting (MAJORITY, UNANIMOUS, THRESHOLD)
Aggregator	Combine results (MERGE, CONCAT, BEST)
HandoffState	Structured agent handoff
build_premise	Structured premise builder
gather_fail_fast	TaskGroup-based parallel execution

Usage Example

from scripts.agentica_patterns.patterns import Swarm, Jury
from scripts.agentica_patterns.primitives import ConsensusMode
from scripts.agentica_patterns.coordination import CoordinationDB
from scripts.agentica_patterns.tracked_agent import tracked_spawn

# Create tracking database
db = CoordinationDB(session_id="my-session")

# Swarm with tracking
swarm = Swarm(
    perspectives=["Security expert", "Performance expert"],
    db=db
)
result = await swarm.execute("Review this code")

# Jury with consensus
jury = Jury(
    num_jurors=3,
    consensus_mode=ConsensusMode.MAJORITY,
    premise="You evaluate code quality",
    db=db
)
verdict = await jury.decide(bool, "Is this code production ready?")
