The Learn–Teach–Master Framework
A Lightweight Python Agent Framework for Observability-First Microservices
When people hear the phrase agent framework, they imagine autonomous AI loops, recursive reasoning engines, and black-box systems making unpredictable decisions.
That’s not what we’re building.
We’re building something far more disciplined.
We’re building a lightweight, deterministic Python agent framework for microservices observability — engineered for production environments where control, clarity, and traceability matter more than novelty.
This is the Learn–Teach–Master Framework.
And it’s built with plain Python.
Why We Built It
Modern microservices environments are complex:
Hundreds of distributed services
Logs in multiple systems
Metrics in Prometheus
Traces in OpenTelemetry
Alerts firing constantly
Continuous deployments
Observability platforms give us data.
But data is not understanding.
Engineers still have to:
Correlate metrics with logs
Interpret latency spikes
Analyze error trends
Explain outages
Summarize incidents
Translate technical findings into executive language
AI can help.
But we do not need autonomous AI chaos.
We need structured intelligence.
What Is the Learn–Teach–Master Framework?
It is a plain Python orchestration layer built inside a FastAPI microservice that:
Learns from telemetry
Teaches through explanation
Masters patterns over time
It is not a heavyweight agent framework.
It is a controlled workflow engine.
Here is the execution model:
Client Request
↓
FastAPI Endpoint
↓
Agent Orchestrator (Python class)
↓
[1] Validate / Enrich Context
↓
[2] Routing / Decision Logic
↓
[3] Tool Execution (optional)
↓
[4] LiteLLM Call
↓
[5] Post-Processing
↓
Response
That’s it.
No hidden loops.
No framework lock-in.
No uncontrolled autonomy.
Just engineering.
The Core Architecture
1. FastAPI Boundary
This handles:
Authentication
Input validation
Rate limiting
Structured requests
The AI logic does not live here.
It lives below.
2. The Agent Orchestrator (Plain Python)
The orchestrator is simply structured code:
class AgentOrchestrator:
def init(self, llm_provider, tools):
self.llm = llm_provider
self.tools = tools
def handle(self, request):
context = self._validate_and_enrich(request)
if self._needs_tool(context):
tool_data = self._execute_tools(context)
context = self._merge(context, tool_data)
response = self.llm.generate(context)
return self._post_process(response)
This is not “AI magic.”
It is a workflow pipeline.
3. The Tool Layer (Observability Integrations)
The framework connects to:
Metrics APIs (Prometheus)
Logs (Elastic, Loki, Datadog)
Traces (OpenTelemetry)
Deployment history
Incident timelines
Health checks
The orchestrator calls these deterministically.
This ensures:
Reproducibility
Auditability
Traceable execution
4. LiteLLM Provider Layer
We use LiteLLM to abstract model providers:
OpenAI
Claude
Gemini
Local models
Bedrock
This gives us:
Vendor portability
Cost control
Model routing
Failover capability
The orchestration logic does not change if the model changes.
Why This Framework Is Different
It Is Deterministic
Every execution path is visible and observable.
You can diagram it.
You can log it.
You can measure it.
That matters in enterprise environments.
It Is Observability-First
The agent itself emits:
Timing metrics
Tool execution logs
LLM latency
Token usage
Health signals
The intelligence layer is observable.
We don’t just analyze systems — we instrument the analyzer.
It Is Vendor-Neutral
We are not locked into a specific LLM provider.
Switching models does not break architecture.
That is critical for long-term strategy.
It Aligns With Learn–Teach–Master
Learn
The framework gathers telemetry and context from distributed systems.
Teach
It explains what is happening in human-readable language.
Master
Over time, patterns, summaries, and structured outputs can be stored and reused, improving diagnosis speed and team knowledge.
This is not just AI assistance.
It is a system-level feedback loop.
Use Cases
Microservice Health Summaries
“Why is latency increasing in payment-service?”
Incident Narrative Generation
“What happened during yesterday’s outage?”
Deployment Impact Analysis
“Did the latest release correlate with error spikes?”
Executive Summaries
“Summarize the system health in non-technical language.”
Why We Did Not Use a Heavy Agent Framework
Most agent frameworks introduce:
Hidden state
Recursive loops
Autonomous tool selection
Complex debugging surfaces
That is risky in production observability systems.
We chose:
Control
Determinism
Traceability
Clarity
Because production systems demand discipline.
Final Thought
The Learn–Teach–Master Framework is not about chasing AI trends.
It is about building a lightweight intelligence layer for distributed systems.
It is plain Python.
It is modular.
It is observable.
And it is powerful enough for:
Enterprise observability platforms
TeamBrain knowledge systems
AI-assisted diagnostics
Sometimes the strongest framework is the one you build yourself — cleanly, intentionally, and with engineering discipline.
