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?")
