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?")Location
