 * **Anticipate Potential Misuse**: Just as humans can err, so can Large Language Models (LLMs). Always assume that any system access or credentials may be used in any way allowed by the permissions they are assigned. For example, if a pair of database credentials allows deleting data, it's safest to assume that any LLM able to use those credentials may in fact delete data.
 * [**Defense in Depth**](https://en.wikipedia.org/wiki/Defense_in_depth_(computing)): No security technique is perfect. Fine-tuning and good chain design can reduce, but not eliminate, the odds that a Large Language Model (LLM) may make a mistake. It's best to combine multiple layered security approaches rather than relying on any single layer of defense to ensure security. For example: use both read-only permissions and sandboxing to ensure that LLMs are only able to access data that is explicitly meant for them to use.

-## Message IDs
-
-LangChain messages include an optional `id` field that serves as a unique identifier. Understanding when and how these IDs are assigned can be helpful for debugging, tracing, and working with message history.
-
-### When Messages Get IDs
-
-Messages receive IDs in the following scenarios:
-
-**Automatically assigned by LangChain:**
-- When generated through chat model invocation (`.invoke()`, `.stream()`, `.astream()`) with an active run manager/tracing context
-- IDs follow the format:
-    - `run-$RUN_ID` (e.g., `run-ba48f958-6402-41a5-b461-5e250a4ebd36-0`)
-    - `run-$RUN_ID-$IDX` (e.g., `run-ba48f958-6402-41a5-b461-5e250a4ebd36-1`) when there are multiple generations from a single chat model invocation.
-
-**Provider-assigned IDs (highest priority):**
-- When the model provider assigns its own ID to the message
-- These take precedence over LangChain-generated run IDs
-- Format varies by provider
-
-### When Messages Don't Get IDs
-
-Messages will **not** receive IDs in these situations:
-
-- **Manual message creation**: Messages created directly (e.g., `AIMessage(content="hello")`) without going through chat models
-- **No run manager context**: When there's no active callback/tracing infrastructure
-
-### ID Priority System

-LangChain follows a clear precedence system for message IDs:
-
-1. **Provider-assigned IDs** (highest priority): IDs from the model provider
-2. **LangChain run IDs** (medium priority): IDs starting with `run-`
-3. **Manual IDs** (lowest priority): IDs explicitly set by users

-## Tool Artifacts vs. Injected State
-
-Although similar conceptually, tool artifacts in LangChain and [injected state in LangGraph](https://langchain-ai.github.io/langgraph/reference/agents/#langgraph.prebuilt.tool_node.InjectedState) serve different purposes and operate at different levels of abstraction.
-
-**Tool Artifacts**
-
-- **Purpose:** Store and pass data between tool executions within a single chain/workflow
-- **Scope:** Limited to tool-to-tool communication
-- **Lifecycle:** Tied to individual tool calls and their immediate context
-- **Usage:** Temporary storage for intermediate results that tools need to share
-
-**Injected State (LangGraph)**
-
-- **Purpose:** Maintain persistent state across the entire graph execution
-- **Scope:** Global to the entire graph workflow
-- **Lifecycle:** Persists throughout the entire graph execution and can be saved/restored
-- **Usage:** Long-term state management, conversation memory, user context, workflow checkpointing
-
-Tool artifacts are ephemeral data passed between tools, while injected state is persistent workflow-level state that survives across multiple steps, tool calls, and even execution sessions in LangGraph.
-
 ## Best practices

-### Pre-commit
-
-We use [pre-commit](https://pre-commit.com/) to ensure commits are formatted/linted.
-
-#### Installing Pre-commit
-
-First, install pre-commit:
-
-```bash
-# Option 1: Using uv (recommended)
-uv tool install pre-commit
-
-# Option 2: Using Homebrew (globally for macOS/Linux)
-brew install pre-commit
-
-# Option 3: Using pip
-pip install pre-commit
-```
-
-Then install the git hook scripts:
-
-```bash
-pre-commit install
-```
-
-#### How Pre-commit Works
-
-Once installed, pre-commit will automatically run on every `git commit`. Hooks are specified in `.pre-commit-config.yaml` and will:
-
-- Format code using `ruff` for the specific library/package you're modifying
-- Only run on files that have changed
-- Prevent commits if formatting fails
-
-#### Skipping Pre-commit
-
-In exceptional cases, you can skip pre-commit hooks with:
-
-```bash
-git commit --no-verify
-```
-
-However, this is discouraged as the CI system will still enforce the same formatting rules.
-

 `langchain`, `langchain-community`, and `langchain-experimental` rely on optional dependencies to keep these packages lightweight.

-# MCP Toolbox
-
-The [MCP Toolbox](https://googleapis.github.io/genai-toolbox/getting-started/introduction/) in LangChain allows you to equip an agent with a set of tools. When the agent receives a query, it can intelligently select and use the most appropriate tool provided by MCP Toolbox to fulfill the request.
-
-## What is it?
-
-MCP Toolbox is essentially a container for your tools. Think of it as a multi-tool device for your agent; it can hold any tools you create. The agent then decides which specific tool to use based on the user's input.
-
-This is particularly useful when you have an agent that needs to perform a variety of tasks that require different capabilities.
-
-## Installation
-
-To get started, you'll need to install the necessary package:
-
-```bash
-pip install toolbox-langchain
-```
-
-## Tutorial
-
-For a complete, step-by-step guide on how to create, configure, and use MCP Toolbox with your agents, please refer to our detailed Jupyter notebook tutorial.

-# TrueFoundry
-
-TrueFoundry provides an enterprise-ready [AI Gateway](https://www.truefoundry.com/ai-gateway) to provide governance and observability to agentic frameworks like LangChain. TrueFoundry AI Gateway serves as a unified interface for LLM access, providing:
-
-- **Unified API Access**: Connect to 250+ LLMs (OpenAI, Claude, Gemini, Groq, Mistral) through one API
-- **Low Latency**: Sub-3ms internal latency with intelligent routing and load balancing
-- **Enterprise Security**: SOC 2, HIPAA, GDPR compliance with RBAC and audit logging
-- **Quota and cost management**: Token-based quotas, rate limiting, and comprehensive usage tracking
-- **Observability**: Full request/response logging, metrics, and traces with customizable retention
-
-
-## Prerequisites
-
-Before integrating LangChain with TrueFoundry, ensure you have:
-
-1. **TrueFoundry Account**: A [TrueFoundry account](https://www.truefoundry.com/register) with at least one model provider configured. Follow quick start guide [here](https://docs.truefoundry.com/gateway/quick-start)
-2. **Personal Access Token**: Generate a token by following the [TrueFoundry token generation guide](https://docs.truefoundry.com/gateway/authentication)
-
-## Quickstart
-
-You can connect to TrueFoundry's unified LLM gateway through the `ChatOpenAI` interface.
-
-- Set the `base_url` to your TrueFoundry endpoint (explained below)
-- Set the `api_key` to your TrueFoundry [PAT (Personal Access Token)](https://docs.truefoundry.com/gateway/authentication#personal-access-token-pat)
-- Use the same `model-name` as shown in the unified code snippet
-
-![TrueFoundry metrics](/img/unified-code-tfy.png)
-
-### Installation
-
-```bash
-pip install langchain-openai
-```
-
-### Basic Setup
-
-Connect to TrueFoundry by updating the `ChatOpenAI` model in LangChain:
-
-```python
-from langchain_openai import ChatOpenAI
-
-llm = ChatOpenAI(
-    api_key=TRUEFOUNDRY_API_KEY,
-    base_url=TRUEFOUNDRY_GATEWAY_BASE_URL,
-    model="openai-main/gpt-4o"  # Similarly you can call any model from any model provider
-)
-
-llm.invoke("What is the meaning of life, universe and everything?")
-```
-
-The request is routed through your TrueFoundry gateway to the specified model provider. TrueFoundry automatically handles rate limiting, load balancing, and observability.
-
-### LangGraph Integration
-
-
-```python
-from langchain_openai import ChatOpenAI
-from langgraph.graph import StateGraph, MessagesState
-from langchain_core.messages import HumanMessage
-
-# Define your LangGraph workflow
-def call_model(state: MessagesState):
-    model = ChatOpenAI(
-        api_key=TRUEFOUNDRY_API_KEY,
-        base_url=TRUEFOUNDRY_GATEWAY_BASE_URL,
-        # Copy the exact model name from gateway
-        model="openai-main/gpt-4o"
-    )
-    response = model.invoke(state["messages"])
-    return {"messages": [response]}
-
-# Build workflow
-workflow = StateGraph(MessagesState)
-workflow.add_node("agent", call_model)
-workflow.set_entry_point("agent")
-workflow.set_finish_point("agent")
-
-app = workflow.compile()
-
-# Run agent through TrueFoundry
-result = app.invoke({"messages": [HumanMessage(content="Hello!")]})
-```
-
-
-## Observability and Governance
-
-![TrueFoundry metrics](/img/gateway-metrics.png)
-
-With the Metrics Dashboard, you can monitor and analyze:
-
-- **Performance Metrics**: Track key latency metrics like Request Latency, Time to First Token (TTFS), and Inter-Token Latency (ITL) with P99, P90, and P50 percentiles
-- **Cost and Token Usage**: Gain visibility into your application's costs with detailed breakdowns of input/output tokens and the associated expenses for each model
-- **Usage Patterns**: Understand how your application is being used with detailed analytics on user activity, model distribution, and team-based usage
-- **Rate Limiting & Load Balancing**: Configure limits, distribute traffic across models, and set up fallbacks
