Logos Router — Distributed Reasoning Skill

Skill by ara.so — MCP Skills collection.

Overview

Logos Router is a distributed semantic reasoning gateway that fragments AI reasoning across local nodes with zero-drift consensus guarantees. Unlike traditional single-model inference pipelines, it distributes subproblems across a mesh of reasoning units that coordinate through a disciplined write protocol. The system maintains reasoning fidelity through cross-validation, preventing the drift common in long-context AI interactions.

Key differentiators:

• Zero-drift consensus: Strict Write Discipline (SWD) protocol validates every reasoning step
• Adaptive depth: Dynamically adjusts cognitive complexity based on problem difficulty
• Multilingual support: 16 languages with unified reasoning representation
• Causal audit trails: Every decision is traceable and verifiable
• Local-first: All reasoning runs on your infrastructure

Core Usage Patterns

Single-Query Reasoning

from logos import Router

# Initialize router with configuration
router = Router(config="mesh_config.yaml")

# Simple query with adaptive depth
response = router.query(
    prompt="Explain the relationship between recursion and self-reference in formal systems.",
    depth="adaptive",  # or specify 1-7
    language="en"
)

print(response.text)
print(f"Reasoning depth used: {response.depth}")
print(f"Nodes consulted: {response.nodes_involved}")
print(f"Consensus score: {response.consensus_score}")

# Access audit trail
for step in response.reasoning_trail:
    print(f"Step {step.index}: {step.action}")
    print(f"  Node: {step.node_id}")
    print(f"  Confidence: {step.confidence}")
    print(f"  Verified by: {step.verifiers}")

Multi-Step Workflow

from logos import Router, Workflow

router = Router(config="mesh_config.yaml")

# Create a multi-step reasoning workflow
workflow = router.create_workflow(
    name="code_analysis",
    description="Analyze code for security and performance issues"
)

# Define workflow steps
workflow.add_step(
    name="extract_structure",
    prompt="Analyze the code structure and identify key components",
    depth=3
)

workflow.add_step(
    name="security_review",
    prompt="Identify potential security vulnerabilities",
    depth=5,
    requires_consensus=True
)

workflow.add_step(
    name="performance_analysis",
    prompt="Analyze performance characteristics and bottlenecks",
    depth=4
)

workflow.add_step(
    name="generate_report",
    prompt="Synthesize findings into a comprehensive report",
    depth=6,
    synthesis_mode="harmonized"
)

# Execute workflow with input
with open("target_code.py", "r") as f:
    code_content = f.read()

result = workflow.execute(input_data={"code": code_content})

# Access workflow results
for step_name, step_result in result.steps.items():
    print(f"\n{step_name}:")
    print(step_result.text)
    print(f"Consensus: {step_result.consensus_score}")

Document Analysis Workflow

from logos import Router

router = Router(config="mesh_config.yaml")

# Create document analysis task
task = router.create_workflow("analyze_research_paper.pdf")

# Chain analysis steps
task.extract_claims()  # Depth 4
task.verify_claims(consensus=True)  # Depth 6, requires 0.95 consensus
task.cross_reference(sources=["./references/"])  # Depth 5
task.generate_summary(style="academic", length=500)  # Depth 4

# Execute with progress tracking
result = task.execute(progress_callback=lambda step, progress: 
    print(f"{step}: {progress * 100:.1f}%")
)

print(result.summary)
print(f"Claims verified: {len(result.verified_claims)}")
print(f"Total reasoning time: {result.execution_time}s")

Multilingual Reasoning

from logos import Router

router = Router(config="mesh_config.yaml")

# Query in Chinese, get response in English
response = router.query(
    prompt="解释量子纠缠的基本原理",  # Chinese input
    depth="adaptive",
    source_language="zh",
    target_language="en"  # Output in English
)

print(response.text)  # English explanation

# Or keep same language
response_zh = router.query(
    prompt="解释量子纠缠的基本原理",
    depth=5,
    language="zh"  # Input and output in Chinese
)

Streaming Reasoning Steps

from logos import Router

router = Router(config="mesh_config.yaml")

# Stream reasoning steps in real-time
for step in router.query_stream(
    prompt="Design a distributed consensus algorithm",
    depth=7
):
    print(f"Node {step.node_id}: {step.text}")
    print(f"  Confidence: {step.confidence:.3f}")
    print(f"  Verification: {step.verification_status}")
    
    # Access intermediate reasoning
    if step.type == "deliberation":
        print(f"  Considering: {step.alternatives}")

Advanced Configuration

Custom Reasoning Profile

Create a custom reasoning profile for specialized domains:

# profiles/scientific_reasoning.yaml
profile:
  name: scientific-reasoning
  max_depth: 7
  
  heuristics:
    - name: hypothesis_generation
      trigger: "problem requires speculation"
      depth_escalation: +2
      
    - name: empirical_verification
      trigger: "factual claim detected"
      requires_consensus: true
      min_verifiers: 3
      
    - name: mathematical_rigor
      trigger: "quantitative reasoning"
      precision_threshold: 0.99
  
  synthesis:
    style: academic
    citation_format: apa
    contradiction_policy: flag_and_escalate

Load custom profile:

from logos import Router

router = Router(
    config="mesh_config.yaml",
    profile="profiles/scientific_reasoning.yaml"
)

response = router.query(
    prompt="Design an experiment to test quantum entanglement",
    use_profile=True
)

Node Capability Manifests

Define specialized node capabilities:

# nodes/math_specialist.yaml
node:
  name: math-reasoning-node
  type: local
  engine: vllm
  model: minerva-540b
  
  capabilities:
    - mathematical_reasoning
    - symbolic_manipulation
    - proof_verification
    
  specializations:
    - domain: calculus
      confidence_boost: 0.15
    - domain: linear_algebra
      confidence_boost: 0.12
      
  resource_limits:
    max_concurrent_queries: 4
    memory_limit: 16GB
    gpu_memory: 24GB

Register specialized node:

from logos import Router

router = Router(config="mesh_config.yaml")

# Register specialized node
router.register_node("nodes/math_specialist.yaml")

# Query will route to specialized node for math problems
response = router.query(
    prompt="Prove that the square root of 2 is irrational",
    prefer_capabilities=["mathematical_reasoning", "proof_verification"]
)

Graceful Degradation Configuration

mesh:
  name: production-mesh
  
  degradation:
    enabled: true
    
    triggers:
      - metric: memory_usage
        threshold: 90%
        action: reduce_depth
        
      - metric: latency
        threshold: 15s
        action: reduce_concurrency
        
      - metric: consensus_failures
        threshold: 3
        action: escalate_and_notify
    
    depth_reduction:
      strategy: proportional  # or "aggressive", "conservative"
      min_depth: 3
      notify_user: true

Troubleshooting

Low Consensus Scores

from logos import Router

router = Router(config="mesh_config.yaml")

# Enable diagnostic mode
router.enable_diagnostics()

response = router.query(
    prompt="Your query here",
    depth=5
)

# Check consensus details
diagnostics = router.get_diagnostics()
for step in diagnostics.consensus_failures:
    print(f"Step {step.index} failed consensus:")
    print(f"  Primary node score: {step.primary_score}")
    print(f"  Verifier scores: {step.verifier_scores}")
    print(f"  Reason: {step.failure_reason}")
    
# Adjust consensus threshold if needed
router.set_consensus_threshold(0.90)  # Lower from 0.95

High Latency Issues

from logos import Router

router = Router(config="mesh_config.yaml")

# Profile query performance
response = router.query(
    prompt="Your query",
    depth=5,
    profile=True
)

# Analyze bottlenecks
print(f"Total time: {response.metrics.total_time}s")
print(f"Node selection: {response.metrics.routing_time}s")
print(f"Inference: {response.metrics.inference_time}s")
print(f"Consensus: {response.metrics.consensus_time}s")
print(f"Synthesis: {response.metrics.synthesis_time}s")

# Optimize by reducing depth or adding nodes
if response.metrics.inference_time > 10.0:
    print("Consider adding more inference nodes")

Memory Pressure

# mesh_config.yaml - Enable aggressive memory management
mesh:
  nodes:
    - name: constrained-node
      memory_limit: 4GB
      swap_to_disk: true
      cache_strategy: aggressive_eviction
      
  grail:
    compression: true
    prune_old_trails: true
    max_trail_size: 100MB

Node Failures

from logos import Router

router = Router(config="mesh_config.yaml")

# Enable automatic failover
router.configure_resilience(
    auto_failover=True,
    health_check_interval=10,  # seconds
    max_retries=3
)

# Monitor node health
for node_id, health in router.get_node_health().items():
    if health.status != "healthy":
        print(f"Node {node_id}: {health.status}")
        print(f"  Last seen: {health.last_seen}")
        print(f"  Error: {health.error_message}")

Debugging Reasoning Trails

from logos import Router

router = Router(config="mesh_config.yaml")

response = router.query(
    prompt="Complex reasoning query",
    depth=7,
    save_trail=True
)

# Export full reasoning trail for inspection
trail = response.export_trail(format="json")

with open("reasoning_trail.json", "w") as f:
    json.dump(trail, f, indent=2)

# Visualize reasoning DAG
from logos.visualization import plot_reasoning_dag

plot_reasoning_dag(
    trail,
    output="reasoning_graph.svg",
    show_consensus=True,
    show_alternatives=True
)

Best Practices

1. Start with adaptive depth: Let the router determine optimal reasoning complexity
2. Use consensus for critical decisions: Enable requires_consensus=True for high-stakes reasoning
3. Monitor consensus scores: Scores below 0.90 indicate potential reasoning issues
4. Profile before scaling: Use diagnostic mode to identify bottlenecks before adding nodes
5. Cache semantic patterns: Enable semantic caching for repeated query patterns
6. Version reasoning profiles: Track profile changes alongside code changes
7. Audit critical trails: Export and review reasoning trails for important decisions

Performance Optimization

from logos import Router

# Production-optimized configuration
router = Router(
    config="mesh_config.yaml",
    cache_enabled=True,
    cache_ttl=3600,  # 1 hour
    parallel_verification=True,
    max_concurrent_queries=10
)

# Batch queries for efficiency
queries = [
    "Query 1",
    "Query 2",
    "Query 3"
]

responses = router.batch_query(
    prompts=queries,
    depth=4,
    max_parallel=3
)

for i, response in enumerate(responses):
    print(f"Query {i+1}: {response.text}")
