## What is Production AI Agents by CS?

Production AI Agents is a practical learning and planning app for engineers who want to move beyond AI demos and build reliable LLM-powered systems.

Read a complete 12-chapter guide, track production readiness, test your understanding, and use focused engineering references for the tradeoffs that matter before deployment: prompts, evaluation, cost, context, latency, retries, queues, error budgets, architecture, troubleshooting, and reliability.

What you can do:

- Read a structured guide to agent architecture, tool use, memory, reliability, observability, security, scaling, and evaluation
- Work through an 8-phase production readiness checklist mapped to the guide chapters
- Use 9 production tools for token cost, context budgets, retries, concurrency, reliability, prompt building, eval sample sizing, error budgets, and queue planning
- Choose an agent architecture with a guided wizard
- Browse a patterns playbook covering ReAct, Plan-and-Execute, multi-agent orchestration, swarms, fan-out, circuit breakers, prompt caching, shadow testing, and model routing
- Diagnose common agent failure modes with a symptom-based troubleshooter
- Copy practical templates for system prompts, retry logic, MCP servers, tracing, guardrails, idempotency, context compaction, and eval harnesses
- Save takeaways, glossary terms, snippets, and patterns to My Library
- Review missed quiz questions and study glossary flashcards with spaced repetition
- Track daily streaks, cards due, bookmarks, quiz results, checklist progress, tool use, and achievements locally on your device
- Generate a shareable completion certificate after finishing the guide, quizzes, and readiness checklist

Production AI Agents is designed for software engineers, ML engineers, AI developers, technical founders, and teams preparing real agentic workflows for production. The app focuses on practical engineering judgment: architecture choices, prompt discipline, failure handling, cost control, security review, evaluation, and operational visibility.

No account is required. Your progress, saved items, review history, settings, streaks, and achievements are stored locally on your device.
