langgraph
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
$langchainwhen the task is mostly prompt/tool chain composition without graph-level orchestration. - Switch to
$ag-uiwhen the task is protocol-level event synchronization with a frontend client. - Switch to
$copilotkitwhen the task is CopilotKit provider/hooks/shared-state UI integration.
Workflow
- Define state schema first. Include only fields required for routing, retries, and outputs.
- Define node contracts. Each node should have one clear responsibility and explicit input/output assumptions.
- Define edges and routers. Map all normal, retry, and terminal paths before implementing node internals.

copilotkit
CopilotKit integration patterns for providers, runtime wiring, `useCoAgent`, `useCopilotAction`, `useLangGraphInterrupt`, shared state, and HITL with LangGraph. Use when building agent-native product UX.
65ag-ui
AG-UI protocol implementation guidance for event ordering (`RUN_STARTED`, `TOOL_CALL_*`, `STATE_SNAPSHOT`/`STATE_DELTA`), streaming semantics, and middleware patterns. Use when integrating agent backends with AG-UI clients.
29mesop
Build Python-native web apps with Mesop. Triggers when users want to build, debug, or deploy Mesop applications, including AI chat interfaces, internal tools, and ML demos.
22plan
Generate a plan for how an agent should accomplish a complex coding task. Use when a user asks for a plan, and optionally when they want to save, find, read, update, or delete plan files in $CODEX_HOME/plans (default ~/.codex/plans).
22code-simplifier
Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Focuses on recently modified code unless instructed otherwise.
22ast-grep
Effective code search, analysis, and refactoring using ast-grep (sg). Use this skill for precise AST-based code modifications, structural search, and linting.
