## Framework Comparison Matrix
| Framework | Loop Detection | Timeout | Circuit Breaker | Retry/Fallback | Multi-Agent | eFIT Alignment |
|-----------|---------------|---------|-----------------|----------------|-------------|----------------|
| **LangGraph** | `recursion_limit: 25` (default) | Per-node execution | Via error handling | State-driven fallback | Supervisor hierarchy | STOPPER + Dialectics |
| **Semantic Kernel** | Via filters | `request_timeout` | Via HttpClient resilience | Filter-based model fallback | Agent handoff (evolving) | Opposite Action + TIPP |
| **CrewAI** | `max_iter: 25` (default) | `max_execution_time` | Multi-stage guardrails | Agent delegation | Dynamic allocation + memory-based conflict resolution | STOPPER + Dialectics |
| **AutoGen** | `MaxMessageTermination` (no default) | `TimeoutTermination` | None (must implement) | Model switching (manual) | Group chat | STOPPER + Opposite Action |
| **AI Proxies** | N/A (gateway) | Per-request | Error rate monitoring | Provider fallback | N/A | TIPP + Distress Tolerance |

## Universal Patterns (Convergent Evolution)
### 1. The "25 Iterations" Convergence
**Finding**: Three major frameworks independently chose **25** as default iteration limit
| Framework | Parameter | Default | Configurable |
|-----------|-----------|---------|--------------|
| LangGraph | `recursion_limit` | 25 | β
|
| CrewAI | `max_iter` | 25 | β
|
| AutoGen | `MaxMessageTermination` | (must set) | β
|
**eFIT Protocol**: **STOPPER - Stop/Observe**
**Implication**: Natural balance point for preventing infinite loops while allowing complex tasks
---
### 2. Retry with Exponential Backoff
**Universal Pattern**: All frameworks use exponential backoff for retries
- Semantic Kernel: 2x backoff factor (default 3 retries)
- ResilientLLM: 2x backoff factor (configurable)
- AI Proxy: Provider-dependent exponential backoff
- Azure APIM: Configurable backoff with `retry-after` header detection
**eFIT Protocol**: **TIPP - Paced Breathing / Temperature Regulation**
**Psychological Parallel**: Gradually slowing down under stress (like paced breathing)
---
### 3. Model/Provider Fallback
**Universal Pattern**: Switch to alternative when primary fails
- Semantic Kernel: GPT-4 β GPT-3.5 (model downgrade)
- AI Proxies: Primary provider β Backup provider (provider switching)
- CrewAI: Agent delegation (agent switching)
- LangGraph: Alternative flows (path switching)
**eFIT Protocol**: **Opposite Action + TIPP**
**Psychological Parallel**: Switching approach when failing (opposite of persisting) + Intensity reduction (downgrade)
---
### 4. Hierarchical Supervision
**Universal Pattern**: Supervisor coordinates specialized agents
- LangGraph: Multi-level supervisor hierarchy
- Semantic Kernel: Orchestrator with agent handoff
- CrewAI: Dynamic task allocation with conflict resolution
- AutoGen: Group chat with coordination
**eFIT Protocol**: **Dialectics + Wise Mind**
**Psychological Parallel**: Supervisor as mediator between conflicting agent perspectives (synthesis)
---
## Quick Code Examples
### LangGraph: Recursion Limit (STOPPER)
```python
from langgraph.errors import GraphRecursionError
config = {"recursion_limit": 100}
try:
app.invoke(inputs, config)
except GraphRecursionError:
# Handle infinite loop detection
print("STOP condition triggered")
```
---
### Semantic Kernel: Retry with Fallback (Opposite Action)
```csharp
public class RetryFilter : IFunctionInvocationFilter
{
public async Task OnFunctionInvocationAsync(context, next)
{
try { await next(context); }
catch (HttpOperationException ex)
{
// Switch to fallback model
context.Arguments.ExecutionSettings["model_id"] = fallbackModel;
await next(context); // Retry
}
}
}
```
---
### CrewAI: Max Iterations & Rate Limiting (STOPPER + TIPP)
```python
agent = Agent(
role='Research Analyst',
max_iter=25, # STOPPER: Iteration limit
max_rpm=60, # TIPP: Rate limiting (pacing)
max_execution_time=300 # TIPP: Timeout
)
```
---
### AutoGen: Termination Conditions (STOPPER)
```python
from autogen_agentchat.conditions import (
TimeoutTermination,
MaxMessageTermination,
ExternalTermination
)
# Multiple STOPPER mechanisms
termination = (
TimeoutTermination(300) | # Time-based stop
MaxMessageTermination(25) | # Iteration-based stop
ExternalTermination() # Human intervention
)
```
---
### ResilientLLM: Circuit Breaker (Distress Tolerance)
```javascript
const llm = new ResilientLLM({
circuitBreaker: {
failureThreshold: 5, // Open after 5 failures
successThreshold: 2, // Close after 2 successes
timeout: 60000 // 60-second "cooling off"
},
rateLimitConfig: {
requestsPerMinute: 60,
llmTokensPerMinute: 90000
},
retries: 3,
backoffFactor: 2
});
```

### Distress Tolerance
**Implementations**:
- ResilientLLM: Circuit breaker with half-open state
- Azure APIM: Circuit breaker with sampling duration
- AI Proxy: Error rate monitoring
- Semantic Kernel: Streaming retry (mid-stream recovery)
**Key Feature**: Accepting temporary failure, cooling off periods
---

## Missing eFIT Protocols
### ABC PLEASE (Physical Welfare)
**Current State**: No frameworks track agent "health" over time
**Recommendation**:
- Add agent-level error rate tracking
- Enforce cooldown periods for consistently failing agents
- Monitor resource usage per agent (token consumption, execution time)
---
### Radical Acceptance
**Current State**: Limited graceful degradation (mostly retry or fail)
**Recommendation**:
- Add "accept reduced quality" modes
- Fallback chains: GPT-4 β GPT-3.5 β Simple heuristic β Cached response
- Explicit "good enough" thresholds
---
### Build Mastery
**Current State**: No learning from failures across sessions
**Recommendation**:
- Persistent error pattern learning
- Track which approaches fail for which query types
- Suggest alternative approaches based on historical failures
---
### Mindfulness (Observe)
**Current State**: Limited observability into agent reasoning mid-execution
**Recommendation**:
- Real-time streaming of agent "thought process"
- Expose internal state transitions
- Observable metrics for each eFIT protocol trigger
---
## Key Insights
### 1. Computational Homology Validated
**Evidence**: 25-iteration convergence across LangGraph, CrewAI, AutoGen
**Implication**: Same problems across substrates (human vs. AI) yield same solutions
**Clinical Psychology Parallel**: STOPPER protocol emerged independently in DBT (humans) and AI orchestration (agents)
---
### 2. Circuit Breakers = Distress Tolerance
**Pattern**: Stop trying after repeated failures, cooling off period, cautious re-engagement
**Implementations**:
- ResilientLLM: 5 failures β 60s open β half-open state
- Azure APIM: 3 failures (30s window) β 1m open β 2 successes to close
- AI Proxy: Dynamic error rate monitoring β priority-based routing
**Psychological Parallel**: "Cooling off period" before re-attempting distressing task
---
### 3. Multi-Level Timeouts = TIPP Hierarchy
**Pattern**: Temperature/Intensity regulation at multiple time scales
**Implementations**:
- Request-level: Individual API calls (seconds)
- Task-level: Function/agent execution (minutes)
- Session-level: Entire conversation (iterations or time)
**Psychological Parallel**: Physiological regulation at multiple scales (breath β posture β environment)
---
### 4. Model Fallback = Opposite Action + TIPP
**Pattern**: Switch to alternative when failing + Reduce intensity
**Implementations**:
- Semantic Kernel: GPT-4 β GPT-3.5 (model downgrade)
- AI Proxies: Primary β Backup provider (provider switch)
- CrewAI: Delegate to different agent (agent switch)
**Psychological Parallel**: "Do the opposite" (switch approach) + "Turn down the temperature" (reduce intensity)
