langgraph
LangGraph state-machine design and debugging for `StateGraph`, node/edge routing, checkpoints, `interrupt`, and HITL flows. Use when building or troubleshooting graph-based agents with conditional edges and thread state.
npx skills add majiayu000/claude-skill-registry --skill langgraph-outlinedriven-odin-codex-plugin --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# LangGraph Use this skill to design, implement, and debug LangGraph workflows with explicit state contracts, deterministic routing, and robust interrupt handling. ## Quick Triage - Use this skill when the task involves graph nodes/edges, conditional routing, checkpointing, thread state, or HITL interrupts. - Switch to `$langchain` when the task is mostly prompt/tool chain composition without graph-level orchestration. - Switch to `$ag-ui` when the task is protocol-level event synchronization with a frontend client. - Switch to `$copilotkit` when the task is CopilotKit provider/hooks/shared-state UI integration. ## Workflow 1. Define state schema first. Include only fields required for routing, retries, and outputs. 2. Define node contracts. Each node should have one clear responsibility and explicit input/output assumptions. 3. Define edges and routers. Map all normal, retry, and terminal paths before implementing node internals. 4. Add persistence strategy. Choose checkpointer configuration and thread identity contract early. 5. Add interrupt strategy. Define where human approvals occur and how resume payloads are parsed. 6. Compile and visualize. Validate graph shape before runn

What does the langgraph skill do?
LangGraph state-machine design and debugging for `StateGraph`, node/edge routing, checkpoints, `interrupt`, and HITL flows. Use when building or troubleshooting graph-based agents with conditional edges and thread state.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill langgraph-outlinedriven-odin-codex-plugin --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
