ai-orchestration-langchain SKILL.md skillA
ai-orchestration-langchain from agents-inc/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add agents-inc/skills/ai-orchestration-langchain@git:20261016.afd0e14Pins git:20261016.afd0e14 in mdr.lock. Pin the fingerprint instead.

LangChain.js patterns for building LLM applications — chat models, LCEL chains, prompt templates, structured output, agents, tools, RAG, streaming, and LangSmith tracing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LangChain.js Patterns > **Quick Guide:** Use LangChain.js (v1.x) to build composable LLM applications. Use LCEL (`prompt.pipe(model).pipe(parser)`) for all chain composition -- never use legacy `LLMChain`. Use `withStructuredOutput(zodSchema)` for typed responses. Use `createAgent()` (LangGraph-backed) for agentic workflows -- `AgentExecutor` is legacy. All `@langchain/*` packages must share the same `@langchain/core` version or you get cryptic type errors at runtime. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST use LCEL pipe composition (`prompt.pipe(model).pipe(parser)`) for all chains -- never use legacy `LLMChain`, `ConversationChain`, or `SequentialChain`)** **(You MUST ensure all `@langchain/*` packages depend on the same version of `@langchain/core` -- version mismatches cause cryptic runtime errors)** **(You MUST use `withStructuredOutput(zodSchema)` for structured LLM responses -- never manually parse JSON from completion text)** **(You MUST use `createAgent()` from `langchain` for new agent code -- `AgentExecutor` and `createToolCallingAgent` are legacy patterns)** …

How to install
mdr add agents-inc/skills/ai-orchestration-langchain@sha256:3364829e6a1fd454The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
