- If you are working with the same repository folder in a container and Windows, you'll want consistent line endings (otherwise you may see hundreds of changes in the SCM view). The `.gitattributes` file in the root of this repo will disable line ending conversion and should prevent this.

Hi there! Thank you for even being interested in contributing to LangChain.
As an open-source project in a rapidly developing field, we are extremely open to contributions, whether they involve new features, improved infrastructure, better documentation, or bug fixes.
To learn how to contribute to LangChain, please follow the [contribution guide here](https://docs.langchain.com/oss/python/contributing).
## 🗺️ Guidelines
### 👩‍💻 Contributing Code
To contribute to this project, please follow the ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow.
Please do not try to push directly to this repo unless you are a maintainer.
Please follow the checked-in pull request template when opening pull requests. Note related issues and tag relevant
maintainers.
Pull requests cannot land without passing the formatting, linting, and testing checks first. See [Testing](#testing) and
[Formatting and Linting](#formatting-and-linting) for how to run these checks locally.
It's essential that we maintain great documentation and testing. If you:
- Fix a bug
- Add a relevant unit or integration test when possible. These live in `tests/unit_tests` and `tests/integration_tests`.
- Make an improvement
- Update any affected example notebooks and documentation. These live in `docs`.
- Update unit and integration tests when relevant.
- Add a feature
- Add a demo notebook in `docs/modules`.
- Add unit and integration tests.
We are a small, progress-oriented team. If there's something you'd like to add or change, opening a pull request is the
best way to get our attention.
### 🚩GitHub Issues
Our [issues](https://github.com/langchain-ai/langchain/issues) page is kept up to date with bugs, improvements, and feature requests.
There is a taxonomy of labels to help with sorting and discovery of issues of interest. Please use these to help organize issues.
If you start working on an issue, please assign it to yourself.
If you are adding an issue, please try to keep it focused on a single, modular bug/improvement/feature.
If two issues are related, or blocking, please link them rather than combining them.
We will try to keep these issues as up-to-date as possible, though
with the rapid rate of development in this field some may get out of date.
If you notice this happening, please let us know.
### 🙋Getting Help
Our goal is to have the simplest developer setup possible. Should you experience any difficulty getting setup, please
contact a maintainer! Not only do we want to help get you unblocked, but we also want to make sure that the process is
smooth for future contributors.
In a similar vein, we do enforce certain linting, formatting, and documentation standards in the codebase.
If you are finding these difficult (or even just annoying) to work with, feel free to contact a maintainer for help -
we do not want these to get in the way of getting good code into the codebase.
## 🚀 Quick Start
This quick start guide explains how to run the repository locally.
For a [development container](https://containers.dev/), see the [.devcontainer folder](https://github.com/langchain-ai/langchain/tree/master/.devcontainer).
### Dependency Management: Poetry and other env/dependency managers
This project utilizes [Poetry](https://python-poetry.org/) v1.6.1+ as a dependency manager.
❗Note: *Before installing Poetry*, if you use `Conda`, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
Install Poetry: **[documentation on how to install it](https://python-poetry.org/docs/#installation)**.
❗Note: If you use `Conda` or `Pyenv` as your environment/package manager, after installing Poetry,
tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
### Core vs. Experimental
This repository contains two separate projects:
- `langchain`: core langchain code, abstractions, and use cases.
- `langchain.experimental`: see the [Experimental README](https://github.com/langchain-ai/langchain/tree/master/libs/experimental/README.md) for more information.
Each of these has its own development environment. Docs are run from the top-level makefile, but development
is split across separate test & release flows.
For this quickstart, start with langchain core:
```bash
cd libs/langchain
```
### Local Development Dependencies
Install langchain development requirements (for running langchain, running examples, linting, formatting, tests, and coverage):
```bash
poetry install --with test
```
Then verify dependency installation:
```bash
make test
```
If the tests don't pass, you may need to pip install additional dependencies, such as `numexpr` and `openapi_schema_pydantic`.
If during installation you receive a `WheelFileValidationError` for `debugpy`, please make sure you are running
Poetry v1.6.1+. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases.
If you are still seeing this bug on v1.6.1, you may also try disabling "modern installation"
(`poetry config installer.modern-installation false`) and re-installing requirements.
See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
### Testing
_some test dependencies are optional; see section about optional dependencies_.
Unit tests cover modular logic that does not require calls to outside APIs.
If you add new logic, please add a unit test.
To run unit tests:
```bash
make test
```
To run unit tests in Docker:
```bash
make docker_tests
```
There are also [integration tests and code-coverage](https://github.com/langchain-ai/langchain/tree/master/libs/langchain/tests/README.md) available.
### Formatting and Linting
Run these locally before submitting a PR; the CI system will check also.
#### Code Formatting
Formatting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/) and [ruff](https://docs.astral.sh/ruff/rules/).
To run formatting for this project:
```bash
make format
```
Additionally, you can run the formatter only on the files that have been modified in your current branch as compared to the master branch using the format_diff command:
```bash
make format_diff
```
This is especially useful when you have made changes to a subset of the project and want to ensure your changes are properly formatted without affecting the rest of the codebase.
#### Linting
Linting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/), [ruff](https://docs.astral.sh/ruff/rules/), and [mypy](http://mypy-lang.org/).
To run linting for this project:
```bash
make lint
```
In addition, you can run the linter only on the files that have been modified in your current branch as compared to the master branch using the lint_diff command:
```bash
make lint_diff
```
This can be very helpful when you've made changes to only certain parts of the project and want to ensure your changes meet the linting standards without having to check the entire codebase.
We recognize linting can be annoying - if you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
#### Spellcheck
Spellchecking for this project is done via [codespell](https://github.com/codespell-project/codespell).
Note that `codespell` finds common typos, so it could have false-positive (correctly spelled but rarely used) and false-negatives (not finding misspelled) words.
To check spelling for this project:
```bash
make spell_check
```
To fix spelling in place:
```bash
make spell_fix
```
If codespell is incorrectly flagging a word, you can skip spellcheck for that word by adding it to the codespell config in the `pyproject.toml` file.
```python
[tool.codespell]
...
# Add here:
ignore-words-list = 'momento,collison,ned,foor,reworkd,parth,whats,aapply,mysogyny,unsecure'
```
## Working with Optional Dependencies
Langchain relies heavily on optional dependencies to keep the Langchain package lightweight.
If you're adding a new dependency to Langchain, assume that it will be an optional dependency, and
that most users won't have it installed.
Users who do not have the dependency installed should be able to **import** your code without
any side effects (no warnings, no errors, no exceptions).
To introduce the dependency to the pyproject.toml file correctly, please do the following:
1. Add the dependency to the main group as an optional dependency
```bash
poetry add --optional [package_name]
```
2. Open pyproject.toml and add the dependency to the `extended_testing` extra
3. Relock the poetry file to update the extra.
```bash
poetry lock --no-update
```
4. Add a unit test that the very least attempts to import the new code. Ideally, the unit
test makes use of lightweight fixtures to test the logic of the code.
5. Please use the `@pytest.mark.requires(package_name)` decorator for any tests that require the dependency.
## Adding a Jupyter Notebook
If you are adding a Jupyter Notebook example, you'll want to install the optional `dev` dependencies.
To install dev dependencies:
```bash
poetry install --with dev
```
Launch a notebook:
```bash
poetry run jupyter notebook
```
When you run `poetry install`, the `langchain` package is installed as editable in the virtualenv, so your new logic can be imported into the notebook.
## Documentation
While the code is split between `langchain` and `langchain.experimental`, the documentation is one holistic thing.
This covers how to get started contributing to documentation.
From the top-level of this repo, install documentation dependencies:
```bash
poetry install
```
### Contribute Documentation
The docs directory contains Documentation and API Reference.
Documentation is built using [Docusaurus 2](https://docusaurus.io/).
API Reference are largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code.
For that reason, we ask that you add good documentation to all classes and methods.
Similar to linting, we recognize documentation can be annoying. If you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
### Build Documentation Locally
In the following commands, the prefix `api_` indicates that those are operations for the API Reference.
Before building the documentation, it is always a good idea to clean the build directory:
```bash
make docs_clean
make api_docs_clean
```
Next, you can build the documentation as outlined below:
```bash
make docs_build
make api_docs_build
```
Finally, run the link checker to ensure all links are valid:
```bash
make docs_linkcheck
make api_docs_linkcheck
```
### Verify Documentation changes
After pushing documentation changes to the repository, you can preview and verify that the changes are
what you wanted by clicking the `View deployment` or `Visit Preview` buttons on the pull request `Conversation` page.
This will take you to a preview of the documentation changes.
This preview is created by [Vercel](https://vercel.com/docs/getting-started-with-vercel).
## 🏭 Release Process
As of now, LangChain has an ad hoc release process: releases are cut with high frequency by
a developer and published to [PyPI](https://pypi.org/project/langchain/).
LangChain follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).
### 🌟 Recognition
If your contribution has made its way into a release, we will want to give you credit on Twitter (only if you want though)!
If you have a Twitter account you would like us to mention, please let us know in the PR or through another means.

# Global Development Guidelines for LangChain Projects
## Core Development Principles
### 1. Maintain Stable Public Interfaces ⚠️ CRITICAL
**Always attempt to preserve function signatures, argument positions, and names for exported/public methods.**
**Bad - Breaking Change:**
```python
def get_user(id, verbose=False): # Changed from `user_id`
pass
```
**Good - Stable Interface:**
```python
def get_user(user_id: str, verbose: bool = False) -> User:
"""Retrieve user by ID with optional verbose output."""
pass
```
**Before making ANY changes to public APIs:**
- Check if the function/class is exported in `__init__.py`
- Look for existing usage patterns in tests and examples
- Use keyword-only arguments for new parameters: `*, new_param: str = "default"`
- Mark experimental features clearly with docstring warnings (using reStructuredText, like `.. warning::`)
🧠 *Ask yourself:* "Would this change break someone's code if they used it last week?"
### 2. Code Quality Standards
**All Python code MUST include type hints and return types.**
**Bad:**
```python
def p(u, d):
return [x for x in u if x not in d]
```
**Good:**
```python
def filter_unknown_users(users: list[str], known_users: set[str]) -> list[str]:
"""Filter out users that are not in the known users set.
Args:
users: List of user identifiers to filter.
known_users: Set of known/valid user identifiers.
Returns:
List of users that are not in the known_users set.
"""
return [user for user in users if user not in known_users]
```
**Style Requirements:**
- Use descriptive, **self-explanatory variable names**. Avoid overly short or cryptic identifiers.
- Attempt to break up complex functions (>20 lines) into smaller, focused functions where it makes sense
- Avoid unnecessary abstraction or premature optimization
- Follow existing patterns in the codebase you're modifying
### 3. Testing Requirements
**Every new feature or bugfix MUST be covered by unit tests.**
**Test Organization:**
- Unit tests: `tests/unit_tests/` (no network calls allowed)
- Integration tests: `tests/integration_tests/` (network calls permitted)
- Use `pytest` as the testing framework
**Test Quality Checklist:**
- [ ] Tests fail when your new logic is broken
- [ ] Happy path is covered
- [ ] Edge cases and error conditions are tested
- [ ] Use fixtures/mocks for external dependencies
- [ ] Tests are deterministic (no flaky tests)
Checklist questions:
- [ ] Does the test suite fail if your new logic is broken?
- [ ] Are all expected behaviors exercised (happy path, invalid input, etc)?
- [ ] Do tests use fixtures or mocks where needed?
```python
def test_filter_unknown_users():
"""Test filtering unknown users from a list."""
users = ["alice", "bob", "charlie"]
known_users = {"alice", "bob"}
result = filter_unknown_users(users, known_users)
assert result == ["charlie"]
assert len(result) == 1
```
### 4. Security and Risk Assessment
**Security Checklist:**
- No `eval()`, `exec()`, or `pickle` on user-controlled input
- Proper exception handling (no bare `except:`) and use a `msg` variable for error messages
- Remove unreachable/commented code before committing
- Race conditions or resource leaks (file handles, sockets, threads).
- Ensure proper resource cleanup (file handles, connections)
**Bad:**
```python
def load_config(path):
with open(path) as f:
return eval(f.read()) # ⚠️ Never eval config
```
**Good:**
```python
import json
def load_config(path: str) -> dict:
with open(path) as f:
return json.load(f)
```
### 5. Documentation Standards
**Use Google-style docstrings with Args section for all public functions.**
**Insufficient Documentation:**
```python
def send_email(to, msg):
"""Send an email to a recipient."""
```
**Complete Documentation:**
```python
def send_email(to: str, msg: str, *, priority: str = "normal") -> bool:
"""
Send an email to a recipient with specified priority.
Args:
to: The email address of the recipient.
msg: The message body to send.
priority: Email priority level (``'low'``, ``'normal'``, ``'high'``).
Returns:
True if email was sent successfully, False otherwise.
Raises:
InvalidEmailError: If the email address format is invalid.
SMTPConnectionError: If unable to connect to email server.
"""
```
**Documentation Guidelines:**
- Types go in function signatures, NOT in docstrings
- Focus on "why" rather than "what" in descriptions
- Document all parameters, return values, and exceptions
- Keep descriptions concise but clear
- Use reStructuredText for docstrings to enable rich formatting
📌 *Tip:* Keep descriptions concise but clear. Only document return values if non-obvious.
### 6. Architectural Improvements
**When you encounter code that could be improved, suggest better designs:**
**Poor Design:**
```python
def process_data(data, db_conn, email_client, logger):
# Function doing too many things
validated = validate_data(data)
result = db_conn.save(validated)
email_client.send_notification(result)
logger.log(f"Processed {len(data)} items")
return result
```
**Better Design:**
```python
@dataclass
class ProcessingResult:
"""Result of data processing operation."""
items_processed: int
success: bool
errors: List[str] = field(default_factory=list)
class DataProcessor:
"""Handles data validation, storage, and notification."""
def __init__(self, db_conn: Database, email_client: EmailClient):
self.db = db_conn
self.email = email_client
def process(self, data: List[dict]) -> ProcessingResult:
"""Process and store data with notifications."""
validated = self._validate_data(data)
result = self.db.save(validated)
self._notify_completion(result)
return result
```
**Design Improvement Areas:**
If there's a **cleaner**, **more scalable**, or **simpler** design, highlight it and suggest improvements that would:
- Reduce code duplication through shared utilities
- Make unit testing easier
- Improve separation of concerns (single responsibility)
- Make unit testing easier through dependency injection
- Add clarity without adding complexity
- Prefer dataclasses for structured data
## Development Tools & Commands
### Package Management
```bash
# Add package
uv add package-name
# Sync project dependencies
uv sync
uv lock
```
### Testing
```bash
# Run unit tests (no network)
make test
# Don't run integration tests, as API keys must be set
# Run specific test file
uv run --group test pytest tests/unit_tests/test_specific.py
```
### Code Quality
```bash
# Lint code
make lint
# Format code
make format
# Type checking
uv run --group lint mypy .
```
### Dependency Management Patterns
**Local Development Dependencies:**
```toml
[tool.uv.sources]
langchain-core = { path = "../core", editable = true }
langchain-tests = { path = "../standard-tests", editable = true }
```
**For tools, use the `@tool` decorator from `langchain_core.tools`:**
```python
from langchain_core.tools import tool
@tool
def search_database(query: str) -> str:
"""Search the database for relevant information.
Args:
query: The search query string.
"""
# Implementation here
return results
```
## Commit Standards
**Use Conventional Commits format for PR titles:**
- `feat(core): add multi-tenant support`
- `fix(cli): resolve flag parsing error`
- `docs: update API usage examples`
- `docs(openai): update API usage examples`
## Framework-Specific Guidelines
- Follow the existing patterns in `langchain-core` for base abstractions
- Use `langchain_core.callbacks` for execution tracking
- Implement proper streaming support where applicable
- Avoid deprecated components like legacy `LLMChain`
### Partner Integrations
- Follow the established patterns in existing partner libraries
- Implement standard interfaces (`BaseChatModel`, `BaseEmbeddings`, etc.)
- Include comprehensive integration tests
- Document API key requirements and authentication
---
## Quick Reference Checklist
Before submitting code changes:
- [ ] **Breaking Changes**: Verified no public API changes
- [ ] **Type Hints**: All functions have complete type annotations
- [ ] **Tests**: New functionality is fully tested
- [ ] **Security**: No dangerous patterns (eval, silent failures, etc.)
- [ ] **Documentation**: Google-style docstrings for public functions
- [ ] **Code Quality**: `make lint` and `make format` pass
- [ ] **Architecture**: Suggested improvements where applicable
- [ ] **Commit Message**: Follows Conventional Commits format

# We explicitly *don't* set up caching here. This ensures our tests are
# maximally sensitive to catching breakage.
#
# For example, here's a way that caching can cause a falsely-passing test:
# - Make the langchain package manifest no longer list a dependency package
# as a requirement. This means it won't be installed by `pip install`,
# and attempting to use it would cause a crash.
# - That dependency used to be required, so it may have been cached.
# When restoring the venv packages from cache, that dependency gets included.
# - Tests pass, because the dependency is present even though it wasn't specified.
# - The package is published, and it breaks on the missing dependency when
# used in the real world.

#
# Examples:
# feat(core): add multitenant support
# fix(cli): resolve flag parsing error
# docs: update API usage examples
# docs(openai): update API usage examples
#
# Allowed Types:
# * feat — a new feature (MINOR)
# * fix — a bug fix (PATCH)
# * docs — documentation only changes (either in /docs or code comments)
# * style — formatting, linting, etc.; no code change or typing refactors
# * refactor — code change that neither fixes a bug nor adds a feature
# * perf — code change that improves performance
# * test — adding tests or correcting existing
# * build — changes that affect the build system/external dependencies
# * ci — continuous integration/configuration changes
# * chore — other changes that don't modify source or test files
# * revert — reverts a previous commit
# * release — prepare a new release

# Global Development Guidelines for LangChain Projects
## Core Development Principles
### 1. Maintain Stable Public Interfaces ⚠️ CRITICAL
**Always attempt to preserve function signatures, argument positions, and names for exported/public methods.**
**Bad - Breaking Change:**
```python
def get_user(id, verbose=False): # Changed from `user_id`
pass
```
**Good - Stable Interface:**
```python
def get_user(user_id: str, verbose: bool = False) -> User:
"""Retrieve user by ID with optional verbose output."""
pass
```
**Before making ANY changes to public APIs:**
- Check if the function/class is exported in `__init__.py`
- Look for existing usage patterns in tests and examples
- Use keyword-only arguments for new parameters: `*, new_param: str = "default"`
- Mark experimental features clearly with docstring warnings (using reStructuredText, like `.. warning::`)
🧠 *Ask yourself:* "Would this change break someone's code if they used it last week?"
### 2. Code Quality Standards
**All Python code MUST include type hints and return types.**
**Bad:**
```python
def p(u, d):
return [x for x in u if x not in d]
```
**Good:**
```python
def filter_unknown_users(users: list[str], known_users: set[str]) -> list[str]:
"""Filter out users that are not in the known users set.
Args:
users: List of user identifiers to filter.
known_users: Set of known/valid user identifiers.
Returns:
List of users that are not in the known_users set.
"""
return [user for user in users if user not in known_users]
```
**Style Requirements:**
- Use descriptive, **self-explanatory variable names**. Avoid overly short or cryptic identifiers.
- Attempt to break up complex functions (>20 lines) into smaller, focused functions where it makes sense
- Avoid unnecessary abstraction or premature optimization
- Follow existing patterns in the codebase you're modifying
### 3. Testing Requirements
**Every new feature or bugfix MUST be covered by unit tests.**
**Test Organization:**
- Unit tests: `tests/unit_tests/` (no network calls allowed)
- Integration tests: `tests/integration_tests/` (network calls permitted)
- Use `pytest` as the testing framework
**Test Quality Checklist:**
- [ ] Tests fail when your new logic is broken
- [ ] Happy path is covered
- [ ] Edge cases and error conditions are tested
- [ ] Use fixtures/mocks for external dependencies
- [ ] Tests are deterministic (no flaky tests)
Checklist questions:
- [ ] Does the test suite fail if your new logic is broken?
- [ ] Are all expected behaviors exercised (happy path, invalid input, etc)?
- [ ] Do tests use fixtures or mocks where needed?
```python
def test_filter_unknown_users():
"""Test filtering unknown users from a list."""
users = ["alice", "bob", "charlie"]
known_users = {"alice", "bob"}
result = filter_unknown_users(users, known_users)
assert result == ["charlie"]
assert len(result) == 1
```
### 4. Security and Risk Assessment
**Security Checklist:**
- No `eval()`, `exec()`, or `pickle` on user-controlled input
- Proper exception handling (no bare `except:`) and use a `msg` variable for error messages
- Remove unreachable/commented code before committing
- Race conditions or resource leaks (file handles, sockets, threads).
- Ensure proper resource cleanup (file handles, connections)
**Bad:**
```python
def load_config(path):
with open(path) as f:
return eval(f.read()) # ⚠️ Never eval config
```
**Good:**
```python
import json
def load_config(path: str) -> dict:
with open(path) as f:
return json.load(f)
```
### 5. Documentation Standards
**Use Google-style docstrings with Args section for all public functions.**
**Insufficient Documentation:**
```python
def send_email(to, msg):
"""Send an email to a recipient."""
```
**Complete Documentation:**
```python
def send_email(to: str, msg: str, *, priority: str = "normal") -> bool:
"""
Send an email to a recipient with specified priority.
Args:
to: The email address of the recipient.
msg: The message body to send.
priority: Email priority level (``'low'``, ``'normal'``, ``'high'``).
Returns:
True if email was sent successfully, False otherwise.
Raises:
InvalidEmailError: If the email address format is invalid.
SMTPConnectionError: If unable to connect to email server.
"""
```
**Documentation Guidelines:**
- Types go in function signatures, NOT in docstrings
- Focus on "why" rather than "what" in descriptions
- Document all parameters, return values, and exceptions
- Keep descriptions concise but clear
- Use reStructuredText for docstrings to enable rich formatting
📌 *Tip:* Keep descriptions concise but clear. Only document return values if non-obvious.
### 6. Architectural Improvements
**When you encounter code that could be improved, suggest better designs:**
**Poor Design:**
```python
def process_data(data, db_conn, email_client, logger):
# Function doing too many things
validated = validate_data(data)
result = db_conn.save(validated)
email_client.send_notification(result)
logger.log(f"Processed {len(data)} items")
return result
```
**Better Design:**
```python
@dataclass
class ProcessingResult:
"""Result of data processing operation."""
items_processed: int
success: bool
errors: List[str] = field(default_factory=list)
class DataProcessor:
"""Handles data validation, storage, and notification."""
def __init__(self, db_conn: Database, email_client: EmailClient):
self.db = db_conn
self.email = email_client
def process(self, data: List[dict]) -> ProcessingResult:
"""Process and store data with notifications."""
validated = self._validate_data(data)
result = self.db.save(validated)
self._notify_completion(result)
return result
```
**Design Improvement Areas:**
If there's a **cleaner**, **more scalable**, or **simpler** design, highlight it and suggest improvements that would:
- Reduce code duplication through shared utilities
- Make unit testing easier
- Improve separation of concerns (single responsibility)
- Make unit testing easier through dependency injection
- Add clarity without adding complexity
- Prefer dataclasses for structured data
## Development Tools & Commands
### Package Management
```bash
# Add package
uv add package-name
# Sync project dependencies
uv sync
uv lock
```
### Testing
```bash
# Run unit tests (no network)
make test
# Don't run integration tests, as API keys must be set
# Run specific test file
uv run --group test pytest tests/unit_tests/test_specific.py
```
### Code Quality
```bash
# Lint code
make lint
# Format code
make format
# Type checking
uv run --group lint mypy .
```
### Dependency Management Patterns
**Local Development Dependencies:**
```toml
[tool.uv.sources]
langchain-core = { path = "../core", editable = true }
langchain-tests = { path = "../standard-tests", editable = true }
```
**For tools, use the `@tool` decorator from `langchain_core.tools`:**
```python
from langchain_core.tools import tool
@tool
def search_database(query: str) -> str:
"""Search the database for relevant information.
Args:
query: The search query string.
"""
# Implementation here
return results
```
## Commit Standards
**Use Conventional Commits format for PR titles:**
- `feat(core): add multi-tenant support`
- `fix(cli): resolve flag parsing error`
- `docs: update API usage examples`
- `docs(openai): update API usage examples`
## Framework-Specific Guidelines
- Follow the existing patterns in `langchain-core` for base abstractions
- Use `langchain_core.callbacks` for execution tracking
- Implement proper streaming support where applicable
- Avoid deprecated components like legacy `LLMChain`
### Partner Integrations
- Follow the established patterns in existing partner libraries
- Implement standard interfaces (`BaseChatModel`, `BaseEmbeddings`, etc.)
- Include comprehensive integration tests
- Document API key requirements and authentication
---
## Quick Reference Checklist
Before submitting code changes:
- [ ] **Breaking Changes**: Verified no public API changes
- [ ] **Type Hints**: All functions have complete type annotations
- [ ] **Tests**: New functionality is fully tested
- [ ] **Security**: No dangerous patterns (eval, silent failures, etc.)
- [ ] **Documentation**: Google-style docstrings for public functions
- [ ] **Code Quality**: `make lint` and `make format` pass
- [ ] **Architecture**: Suggested improvements where applicable
- [ ] **Commit Message**: Follows Conventional Commits format

# Migrating
# Migrating to `langchain_experimental`
Please see the following guides for migrating LangChain code:
We are moving any experimental components of LangChain, or components with vulnerability issues, into `langchain_experimental`.
This guide covers how to migrate.
* Migrate to [LangChain v0.3](https://python.langchain.com/docs/versions/v0_3/)
* Migrate to [LangChain v0.2](https://python.langchain.com/docs/versions/v0_2/)
* Migrating from [LangChain 0.0.x Chains](https://python.langchain.com/docs/versions/migrating_chains/)
* Upgrade to [LangGraph Memory](https://python.langchain.com/docs/versions/migrating_memory/)
## Installation
The [LangChain CLI](https://python.langchain.com/docs/versions/v0_3/#migrate-using-langchain-cli) can help you automatically upgrade your code to use non-deprecated imports.
This will be especially helpful if you're still on either version 0.0.x or 0.1.x of LangChain.
Previously:
`pip install -U langchain`
Now (only if you want to access things in experimental):
`pip install -U langchain langchain_experimental`
## Things in `langchain.experimental`
Previously:
`from langchain.experimental import ...`
Now:
`from langchain_experimental import ...`
## PALChain
Previously:
`from langchain.chains import PALChain`
Now:
`from langchain_experimental.pal_chain import PALChain`
## SQLDatabaseChain
Previously:
`from langchain.chains import SQLDatabaseChain`
Now:
`from langchain_experimental.sql import SQLDatabaseChain`
Alternatively, if you are just interested in using the query generation part of the SQL chain, you can check out [`create_sql_query_chain`](https://github.com/langchain-ai/langchain/blob/master/docs/extras/use_cases/tabular/sql_query.ipynb)
`from langchain.chains import create_sql_query_chain`
## `load_prompt` for Python files
Note: this only applies if you want to load Python files as prompts.
If you want to load json/yaml files, no change is needed.
Previously:
`from langchain.prompts import load_prompt`
Now:
`from langchain_experimental.prompts import load_prompt`

## 🚨Breaking Changes for select chains (SQLDatabase) on 7/28/23
## Why use LangChain?
In an effort to make `langchain` leaner and safer, we are moving select chains to `langchain_experimental`.
This migration has already started, but we are remaining backwards compatible until 7/28.
On that date, we will remove functionality from `langchain`.
Read more about the motivation and the progress [here](https://github.com/langchain-ai/langchain/discussions/8043).
Read how to migrate your code [here](MIGRATE.md).
LangChain helps developers build applications powered by LLMs through a standard
interface for models, embeddings, vector stores, and more.
## Quick Install
Use LangChain for:
`pip install langchain`
or
`pip install langsmith && conda install langchain -c conda-forge`
- **Real-time data augmentation**. Easily connect LLMs to diverse data sources and
external/internal systems, drawing from LangChains vast library of integrations with
model providers, tools, vector stores, retrievers, and more.
- **Model interoperability**. Swap models in and out as your engineering team
experiments to find the best choice for your applications needs. As the industry
frontier evolves, adapt quickly — LangChains abstractions keep you moving without
losing momentum.
## 🤔 What is this?
## LangChains ecosystem
Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. However, using these LLMs in isolation is often insufficient for creating a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge.
While the LangChain framework can be used standalone, it also integrates seamlessly
with any LangChain product, giving developers a full suite of tools when building LLM
applications.
This library aims to assist in the development of those types of applications. Common examples of these applications include:
To improve your LLM application development, pair LangChain with:

## 🚀 What can this help with?
There are six main areas that LangChain is designed to help with.
These are, in increasing order of complexity:
**📃 LLMs and Prompts:**
This includes prompt management, prompt optimization, a generic interface for all LLMs, and common utilities for working with LLMs.
**🔗 Chains:**
Chains go beyond a single LLM call and involve sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.
**📚 Data Augmented Generation:**
Data Augmented Generation involves specific types of chains that first interact with an external data source to fetch data for use in the generation step. Examples include summarization of long pieces of text and question/answering over specific data sources.
**🤖 Agents:**
Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end-to-end agents.
**🧠 Memory:**
Memory refers to persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.
**🧐 Evaluation:**
[BETA] Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is by using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.
For more information on these concepts, please see our [full documentation](https://python.langchain.com).

# Security Policy
LangChain has a large ecosystem of integrations with various external resources like local and remote file systems, APIs and databases. These integrations allow developers to create versatile applications that combine the power of LLMs with the ability to access, interact with and manipulate external resources.
## Reporting a Vulnerability
## Best practices
When building such applications, developers should remember to follow good security practices:
* [**Limit Permissions**](https://en.wikipedia.org/wiki/Principle_of_least_privilege): Scope permissions specifically to the application's need. Granting broad or excessive permissions can introduce significant security vulnerabilities. To avoid such vulnerabilities, consider using read-only credentials, disallowing access to sensitive resources, using sandboxing techniques (such as running inside a container), specifying proxy configurations to control external requests, etc., as appropriate for your application.
* **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.
Risks of not doing so include, but are not limited to:
* Data corruption or loss.
* Unauthorized access to confidential information.
* Compromised performance or availability of critical resources.
Example scenarios with mitigation strategies:
* A user may ask an agent with access to the file system to delete files that should not be deleted or read the content of files that contain sensitive information. To mitigate, limit the agent to only use a specific directory and only allow it to read or write files that are safe to read or write. Consider further sandboxing the agent by running it in a container.
* A user may ask an agent with write access to an external API to write malicious data to the API, or delete data from that API. To mitigate, give the agent read-only API keys, or limit it to only use endpoints that are already resistant to such misuse.
* A user may ask an agent with access to a database to drop a table or mutate the schema. To mitigate, scope the credentials to only the tables that the agent needs to access and consider issuing READ-ONLY credentials.
If you're building applications that access external resources like file systems, APIs or databases, consider speaking with your company's security team to determine how to best design and secure your applications.
## Reporting OSS Vulnerabilities
LangChain is partnered with [huntr by Protect AI](https://huntr.com/) to provide
a bounty program for our open source projects.
Please report security vulnerabilities associated with the LangChain
open source projects at [huntr](https://huntr.com/bounties/disclose/?target=https%3A%2F%2Fgithub.com%2Flangchain-ai%2Flangchain&validSearch=true).
Before reporting a vulnerability, please review:
1) In-Scope Targets and Out-of-Scope Targets below.
2) The [langchain-ai/langchain](https://docs.langchain.com/oss/python/contributing/code#supporting-packages) monorepo structure.
3) The [Best Practices](#best-practices) above to understand what we consider to be a security vulnerability vs. developer responsibility.
### In-Scope Targets
The following packages and repositories are eligible for bug bounties:
* langchain-core
* langchain (see exceptions)
* langchain-community (see exceptions)
* langgraph
* langserve
### Out of Scope Targets
All out of scope targets defined by huntr as well as:
* **langchain-experimental**: This repository is for experimental code and is not
eligible for bug bounties (see [package warning](https://pypi.org/project/langchain-experimental/)), bug reports to it will be marked as interesting or waste of
time and published with no bounty attached.
* **tools**: Tools in either langchain or langchain-community are not eligible for bug
bounties. This includes the following directories
* libs/langchain/langchain/tools
* libs/community/langchain_community/tools
* Please review the [Best Practices](#best-practices)
for more details, but generally tools interact with the real world. Developers are
expected to understand the security implications of their code and are responsible
for the security of their tools.
* Code documented with security notices. This will be decided on a case-by-case basis, but likely will not be eligible for a bounty as the code is already
documented with guidelines for developers that should be followed for making their
application secure.
* Any LangSmith related repositories or APIs (see [Reporting LangSmith Vulnerabilities](#reporting-langsmith-vulnerabilities)).
## Reporting LangSmith Vulnerabilities
Please report security vulnerabilities associated with LangSmith by email to `security@langchain.dev`.
* LangSmith site: [https://smith.langchain.com](https://smith.langchain.com)
* SDK client: [https://github.com/langchain-ai/langsmith-sdk](https://github.com/langchain-ai/langsmith-sdk)
### Other Security Concerns

If the vector database lacks relevant information, the agent opts for web search. Open-source models for LLM and embeddings are used locally on an Intel Xeon CPU to execute this pipeline.
[rag_mlflow_tracking_evaluation.ipynb](https://github.com/langchain-ai/langchain/tree/master/cookbook/rag_mlflow_tracking_evaluation.ipynb) | Guide on how to create a RAG pipeline and track + evaluate it with MLflow.

"# Combine agents and vector stores\n",
"\n",
"This notebook covers how to combine agents and vector stores. The use case for this is that you've ingested your data into a vector store and want to interact with it in an agentic manner.\n",
"\n",
"The recommended method for doing so is to create a `RetrievalQA` and then use that as a tool in the overall agent. Let's take a look at doing this below. You can do this with multiple different vector DBs, and use the agent as a way to route between them. There are two different ways of doing this - you can either let the agent use the vector stores as normal tools, or you can set `return_direct=True` to really just use the agent as a router."

"### Why route chat messages through Kafka?\n",
"\n",
"It's easier to interact with the LLM directly using LangChains built-in conversation management features. Plus you can also use a REST API to generate a response from an externally hosted model. So why go to the trouble of using Apache Kafka?\n",
"\n",
"There are a few reasons, such as:\n",
"\n",
" * **Integration**: Many enterprises want to run their own LLMs so that they can keep their data in-house. This requires integrating LLM-powered components into existing architectures that might already be decoupled using some kind of message bus.\n",
"\n",
" * **Scalability**: Apache Kafka is designed with parallel processing in mind, so many teams prefer to use it to more effectively distribute work to available workers (in this case the \"worker\" is a container running an LLM).\n",
"\n",
" * **Durability**: Kafka is designed to allow services to pick up where another service left off in the case where that service experienced a memory issue or went offline. This prevents data loss in highly complex, distributed architectures where multiple systems are communicating with one another (LLMs being just one of many interdependent systems that also include vector databases and traditional databases).\n",
"\n",
"For more background on why event streaming is a good fit for Gen AI application architecture, see Kai Waehner's article [\"Apache Kafka + Vector Database + LLM = Real-Time GenAI\"](https://www.kai-waehner.de/blog/2023/11/08/apache-kafka-flink-vector-database-llm-real-time-genai/)."
