+
+## 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.

+### 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.
+

+## Snapshot Testing
+
+Some tests use [syrupy](https://github.com/tophat/syrupy) for snapshot testing, which captures the output of functions and compares them to stored snapshots. This is particularly useful for testing JSON schema generation and other structured outputs.
+
+### Updating Snapshots
+
+To update snapshots when the expected output has legitimately changed:
+
+```bash
+uv run --group test pytest path/to/test.py --snapshot-update
+```
+
+### Pydantic Version Compatibility Issues
+
+Pydantic generates different JSON schemas across versions, which can cause snapshot test failures in CI when tests run with different Pydantic versions than what was used to generate the snapshots.
+
+**Symptoms:**
+- CI fails with snapshot mismatches showing differences like missing or extra fields.
+- Tests pass locally but fail in CI with different Pydantic versions
+
+**Solution:**
+Locally update snapshots using the same Pydantic version that CI uses:
+
+1. **Identify the failing Pydantic version** from CI logs (e.g., `2.7.0`, `2.8.0`, `2.9.0`)
+
+2. **Update snapshots with that version:**
+   ```bash
+   uv run --with "pydantic==2.9.0" --group test pytest tests/unit_tests/path/to/test.py::test_name --snapshot-update
+   ```
+
+3. **Verify compatibility across supported versions:**
+   ```bash
+   # Test with the version you used to update
+   uv run --with "pydantic==2.9.0" --group test pytest tests/unit_tests/path/to/test.py::test_name
+
+   # Test with other supported versions
+   uv run --with "pydantic==2.8.0" --group test pytest tests/unit_tests/path/to/test.py::test_name
+   ```
+
+**Note:** Some tests use `@pytest.mark.skipif` decorators to only run with specific Pydantic version ranges (e.g., `PYDANTIC_VERSION_AT_LEAST_210`). Make sure to understand these constraints when updating snapshots.
+
 ## Coverage
 
 Code coverage (i.e. the amount of code that is covered by unit tests) helps identify areas of the code that are potentially more or less brittle.

+# 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
+
