langchain-azure-js: Instructions file for Codex

AGENTS.md

langchain-azure-js AGENTS.md is an instructions file for Codex, OpenCode from langchain-ai/langchain-azure-js. It costs 2,110 tokens per session, scanned A, original, MIT.

Repository guidance stored in AGENTS.md files for a JavaScript and TypeScript monorepo, a repository containing multiple related packages. It describes the project’s purpose, Azure authentication, development rules, and compatibility with LangChain.js and LangGraph.js.

In plain words
What is it for?
Guiding API changes, package development, testing, documentation, and decisions that should remain compatible with the related LangChain projects.
Why use it?
It gives coding agents the local rules and reference points they need before changing the repository.

This is langchain-ai/langchain-azure-js's own configuration. It tells Codex and OpenCode how to work on langchain-azure-js itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything langchain-azure-js configures →

About the project

langchain-ai/langchain-azure-js is an early-stage JavaScript integration project that connects LangChain.js and LangGraph.js applications with Microsoft Azure AI services. It is intended for developers building LangChain-compatible applications with Azure models and services using standard runnables and Azure SDK clients. The catalogue instruction relates to using this repository's integration scaffolding.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

langchain-azure-js AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Guidelines

Purpose and Scope

  • This monorepo provides SDKs that help LangChain.js and LangGraph.js users connect to Azure resources.
  • Treat LangChain.js and LangGraph.js as the upstream compatibility references.
  • Use langchain-azure, the Python counterpart, as a secondary reference for feature coverage, service behavior, and design lessons. Aim for long-term capability convergence rather than line-by-line parity, and account for differences between the JavaScript and Python Azure SDKs and language ecosystems.
  • A nested AGENTS.md extends these repository-wide instructions for its package. Follow both files; when guidance conflicts, the instruction closest to the edited file takes precedence.
  • Keep agent instructions in hierarchical AGENTS.md files. Do not add parallel copilot-instructions.md or *.instructions.md files.

Upstream Compatibility

  • Before designing or changing a public API, find the analogous upstream abstraction, implementation, tests, and documentation. Prefer upstream names, signatures, option shapes, return types, and lifecycle semantics.
  • Preserve LangChain contracts for runnables, callbacks, streaming, tool calling, serialization, tracing, cancellation, and standardized input/output types wherever they apply.
  • Keep integrations naturally usable from LangGraph.js. Prefer shared LangChain primitives over graph-specific wrappers unless the feature is inherently graph-specific.
  • Introduce Azure-specific behavior only where the service requires it. Keep it additive and document any deliberate divergence from upstream behavior.
  • Do not copy an upstream implementation blindly. Reconcile it with this repository's supported @langchain/core, Azure SDK, TypeScript, and runtime versions.
  • Treat public exports, constructor options, serialized fields, and environment-variable names as compatibility surfaces. Avoid breaking them without an explicit migration plan and tests.
  • Preserve published APIs by default. Change a public API only when a new capability or a deliberate change in the product's mental model requires it; align the new shape with LangChain.js conventions and clearly communicate compatibility impact and migration guidance to users.
  • Prefer additive evolution and deprecation periods over immediate removal or renaming of published APIs. Record any public compatibility impact, before-and-after usage, and migration guidance in the corresponding SDK documentation.
  • Refine internal interfaces proactively as understanding improves. Internal parameter shapes and module boundaries may change when doing so makes the implementation simpler, more coherent, or easier to extend.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
