LangGraph in Python: State, Parallel Nodes, Checkpoints and Human Review
A hands-on LangGraph tour in Python: TypedDict state and reducers, edges, checkpointers, interrupts, and an email triage workflow with human approval.
25 min readLoops vs. Graphs: Two Ways to Architect AI Agents
Loop engineering vs graph engineering for AI agents: how each architecture works, when to pick one over the other, and a checklist to use before production.
12 min readReplay-Safe Agents: Keeping LLM Calls Out of the Workflow With Temporal
Why an agent that crashes mid-run must not re-fire its LLM: activities as a non-determinism boundary, replay mechanics, heartbeats, retries and stateless graphs.
16 min readGraph Engineering for AI Coding Agents: Context, Contracts and Repair
What a contract-driven agent graph taught one developer: scoped context, deterministic validation, targeted repair, and when the extra compute cost is justified.
11 min readWorkflows vs Agents: Who Should Choose the Next Research Step?
Workflows vs agents for research: when to hard-code the path and when the model should pick the next search, with a LangGraph and Anthropic web tools design.
5 min readLangGraph Conditional Edges: Routing a Graph With State and Decisions
Learn how LangGraph conditional edges work: write a router that stores its decision in state, map outcomes to nodes and send each path where it should go.
5 min readPractical notes: 3 Lessons I Learned Building Agentic Workflows
Operable walkthrough of Practical notes: 3 Lessons I Learned Building Agentic Workflows: contracts, checks, and drop-in code slots for teams shipping this pattern.
6 min readLangGraph Conditional Workflows: Branching Without Prompt Spaghetti
Encode LangGraph if-else routing as named conditional edges with clear state contracts and recoverable failures, instead of stuffing branching into prompts.
10 min readBeyond Linear Scripts: LangGraph Nodes, Edges, and Durable State
Swap brittle LLM loops for LangGraph graphs: specialized nodes, explicit state schemas, branching edges, human approval gates and paths that survive failures.
