Agentic Workflow - Patterns, Security, and Production Design
An agentic workflow is a multi-step AI process where agents autonomously choose tools, delegate subtasks, and adapt based on intermediate results. Core patterns, failure modes, and security design.
AI Agent Architecture — Layers, Topologies, and Security-First Design
AI agent architecture: four structural layers (perception, reasoning, memory, action), single vs multi-agent topologies, ReAct loop, and 2025 cross-agent standards (Google A2A, OpenAI handoffs).
AI Agent Context Window — Management, Limits, and Security
AI agent context window management: token budgets, context poisoning via OWASP LLM01:2025, compression strategies, and how OpenLegion enforces per-agent context isolation.
AI Agent Evaluation: Benchmarks, Metrics, and Testing
AI agent evaluation is the discipline of measuring whether agents reliably complete tasks, use tools safely, and stay within cost bounds — covering benchmarks, LLM-as-judge, and trace analysis.

AI agent security guide: credential leakage, prompt injection, sandbox escape, and how container isolation, vault-proxied credentials, and budget controls mitigate each threat.
AI Agent State Management — Checkpointing, Shared State, and Crash Recovery
Checkpointing, shared state, and crash recovery for AI agents. Covers LangGraph checkpointers, transactional blackboard writes, reducer patterns, snapshot isolation, and cross-agent synchronization.
AI Agent Tool Use — Function Calling, Schemas, and Safe Execution
How AI agents use tools: defining tool schemas, function calling across providers, parallel and chained calls, output parsing, error recovery, and permission scoping for safe production execution.
AI Coding Agents - Deploy Secure Dev Agent Teams
AI coding agents that plan, write, test, and review code autonomously. OpenLegion runs them in isolated containers with vaulted credentials and per-agent budgets - a self-hostable dev agent team.
Browser Use Agents — How AI Agents Control the Web
Browser use agents let AI autonomously navigate websites, fill forms, and extract data. Learn how they work, their security risks, and how to run them safely in isolated containers.
