Agents
Model Context Protocol (MCP) in 2026 — What It Solved, What It Didn't
Practical MCP: building an MCP server, integrating with Claude / Cursor, when MCP wins, and the security pitfalls of remote tool access.
Agentic Coding in 2026 — Claude Code, Cursor, and the Real Workflow
Honest take on AI coding agents: where Claude Code / Cursor shine, when they hurt, the discipline of using them well, and what stays human.
LLM Agent Frameworks in 2026 — LangGraph, CrewAI, and the Bare-Metal Alternative
Honest agent framework comparison: LangGraph for stateful workflows, CrewAI for multi-agent, OpenAI Agents SDK, and where 200 lines of Python beats them all.
Agent Memory Systems in 2026 — Episodic, Semantic, and the Patterns That Stick
Practical agent memory: working memory in the prompt, episodic memory in append-only stores, semantic memory in vector DBs, and how to compose them.
LLM Agent Error Recovery in 2026 — Patterns That Don't Loop Forever
Production agent error handling. Per-tool retries vs whole-agent retries, fallback paths, step caps, escalation, human-in-the-loop, and the patterns from real agent deployments.
Designing Tools for AI Agents in 2026 — The Patterns That Work
Tool design for agents — names, descriptions as prompts, input schemas, error handling, idempotency, and the patterns that make agents call them correctly.
Giving AI Agents Memory in 2026 — Mem0, Zep, and the Patterns That Work
Why agents need memory beyond the context window, the 2026 tools (Mem0, Zep, custom layers), summary vs episodic memory, retrieval, and the patterns from production agents.
Sandboxed Code Execution for AI Agents — E2B, Modal, Daytona, and the 2026 Stack
Why agents need sandboxed code execution, the 2026 platforms (E2B, Modal, Daytona, Fly Machines, custom microVMs), tradeoffs, and how to wire it into an agent.
Agentic RAG in 2026 — When Retrieval Becomes a Tool, Not a Pipeline
Why agentic RAG often beats one-shot RAG. Tool-based retrieval, decomposition, query rewriting, self-reflection, citations, and the production patterns that ship in 2026.
