Article 1Data Pipeline Orchestration Pattern: DAG Scheduling, Retries, and RecoveryTLDR: Pipeline orchestration is an operational control plane problem that requires explicit dependency, retry, and backfill contracts.
TLDR: Pipeline orchestration is less about drawing DAGs and mor14 minArticle 2Human-in-the-Loop Workflows with LangGraph: Interrupts, Approvals, and Async ExecutionTLDR: Pause LangGraph agents mid-run with interrupt(), get human approval, resume with Command.
š The Autonomous Agent Risk: When Acting Without Permission Goes Wrong
Your autonomous coding agent r18 minArticle 3Saga Pattern: Coordinating Distributed Transactions with CompensationTLDR: A Saga replaces fragile distributed 2PC with a sequence of local transactions, each backed by an explicit compensating transaction. Use orchestration when workflow control needs a single brain; 15 minArticle 4Dead Letter Queue Pattern: Isolating Poison Messages and Recovering SafelyTLDR: A dead letter queue protects throughput by moving repeatedly failing messages out of the hot path. It only works if retries are bounded, triage has an owner, and replay is a deliberate workflow 14 min
Article 5Skills vs LangChain, LangGraph, MCP, and Tools: A Practical Architecture GuideTLDR: These are not competing ideas. They are layers. Tools do one action. MCP standardizes access to actions and resources. LangChain and LangGraph orchestrate calls. Skills package business outcomes15 min
Article 6LLM Skills vs Tools: The Missing Layer in Agent DesignTLDR: A tool is a single callable capability (search, SQL, calculator). A skill is a reusable mini-workflow that coordinates multiple tool calls with policy, guardrails, retries, and output structure.16 min
