12-Step Blueprint for Building Production AI Agents — Part I
This MLPills newsletter issue presents the first half (steps 1–6) of a 12-step blueprint for designing production-ready AI agents. It frames agents as orchestrated systems rather than single models and covers foundational topics: defining use cases, success criteria and constraints; crafting system prompts (role, instructions, guardrails, output formatting); selecting and routing LLMs by capability, context window, cost and latency; designing tools and connectors (atomic tools, custom functions, MCP protocol, multi-agent orchestration); enforcing security (scoped credentials, input sanitization, action scoping, audit logging); and the need for a memory architecture. The piece includes practical examples (fraud detection, customer support triage, multi-model code-review pipelines) and mentions an associated paid course by Towards AI and Paul Iusztin.
Provides practical systems design guidance for building production AI agents—useful for engineering teams across AdTech/MarTech but not an industry-shifting announcement.

Key Takeaways & Evidence Grounding
- MLPills issue outlines steps 1–6 of a 12-step blueprint for building production-ready AI agents.
- Core design topics covered: use-case scoping, system prompt design, LLM selection and multi-model routing, tool design and orchestration, security controls, and memory architecture.
- Recommends tool principles (atomic tools, explicit schemas), use of an MCP (Model Context Protocol) for secure data access, and audit logging for every tool invocation.
- Provides concrete examples: fraud detection agent, customer support triage agent with JSON output, and a multi-model code-review agent using distinct Claude variants.
- Mentions a paid course titled 'Your Path to Agentic AI for Production' by Towards AI and Paul Iusztin.

12-Step AI Agent Blueprint — Part II
MLPills Issue #123 (Part II) continues a practical 12-step blueprint for taking an AI agent from prototype to production. The article covers orchestration (routes, triggers, error handling, conditional logic), human-in-the-loop checkpoints (approval gates, confidence thresholds, escalation paths), interface patterns (chat, dashboards, APIs, Slack/Discord bots), observability (tracing, token/cost tracking, latency and error dashboards), and production deployment considerations (containerization, serverless vs persistent compute, queue-based architectures, externalized state). It includes concrete examples—LangGraph orchestration for content pipelines, legal-review escalation flows, and an SQS+ECS Fargate data pipeline—and cites tooling such as LangSmith, Arize Phoenix, OpenTelemetry, Grafana and common cloud primitives (Lambda, SQS, Redis). The issue also advertises a paid course by Towards AI and Paul Iusztin.
AI Agents in Practice — Series Overview
A DEV Community article by Gursharan Singh (published 2026-05-23) presents an actively maintained, vendor-neutral series called “AI Agents in Practice.” The series focuses on building production-grade AI agents from first principles — explaining why prototype demos fail in production, what qualifies as an agent (a control loop with tools, state, and boundaries), and the core primitives (MCP for acting, RAG for knowledge, and reusable Skills). Part 1 and Part 2 are linked; Part 3 on agent execution loops is forthcoming. The post positions the series as practical and production-oriented, emphasizing patterns, engineering constraints (state, context, stopping conditions), and integrations with tool-calling and retrieval pipelines.
Micro Agents as Production-Grade Microservices
A technical guide explaining how to build production-grade AI agent systems by treating each autonomous capability as an independently deployable microservice. The article covers architecture and engineering patterns including FastAPI/gRPC service design, async task queues (Kafka), external memory (Redis, Qdrant), a centralized Tool Registry with JSON Schema contracts, observability via OpenTelemetry and Prometheus, Kubernetes deployment and HPA policies, fault-tolerance (circuit breakers, retries, DLQs, checkpointing), multi-model fallback strategies, security (JWT, RBAC, secrets in Vault), testing practices, CI/CD, and cost/token budgeting. It provides code examples (AgentRunner loop, ContextManager, gRPC/Avro schemas), recommended metrics/alerts, and a production-readiness checklist for operating LLM-backed agents at scale.
