49ca02711e Improved query, print & exception handling in REPL Tool (#4997)
Update to pull request https://github.com/hwchase17/langchain/pull/3215

Summary:
1) Improved the sanitization of query (using regex), by removing python
command (since gpt-3.5-turbo sometimes assumes python console as a
terminal, and runs python command first which causes error). Also
sometimes 1 line python codes contain single backticks.
2) Added 7 new test cases.

For more details, view the previous pull request.

ef7d015be5 Separate Runner Functions from Client (#5079)
Extract the methods specific to running an LLM or Chain on a dataset to
separate utility functions.

This simplifies the client a bit and lets us separate concerns of LCP
details from running examples (e.g., for evals)

443ebe22f4 docs: Deployments page moved into Ecosystem/ (#4949)
# docs: `deployments` page moved into `ecosystem/`

The `Deployments` page moved into the `Ecosystem/` group

Small fixes:
- `index` page: fixed order of items in the `Modules` list, in the `Use
Cases` list
- item `References/Installation` was lost in the `index` page (not on
the Navbar!). Restored it.
- added `|` marker in several places.

NOTE: I also thought about moving the `Additional Resources/Gallery`
page into the `Ecosystem` group but decided to leave it unchanged.
Please, advise on this.

a395ff7c90 preserve language in conversation retrieval (#4969)
Without the addition of 'in its original language', the condensing
response, more often than not, outputs the rephrased question in
English, even when the conversation is in another language. This
question in English then transfers to the question in the retrieval
prompt and the chatbot is stuck in English.

I'm sometimes surprised that this does not happen more often, but
apparently the GPT models are smart enough to understand that when the
template contains

Question: ....
Answer:

then the answer should be in in the language of the question.

bf3f554357 feat: batch multiple files in a single Unstructured API request (#4525)
### Submit Multiple Files to the Unstructured API

Enables batching multiple files into a single Unstructured API requests.
Support for requests with multiple files was added to both
`UnstructuredAPIFileLoader` and `UnstructuredAPIFileIOLoader`. Note that
if you submit multiple files in "single" mode, the result will be
concatenated into a single document. We recommend using this feature in
"elements" mode.

### Testing

The following should load both documents, using two of the example docs
from the integration tests folder.

```python
    from langchain.document_loaders import UnstructuredAPIFileLoader

    file_paths = ["examples/layout-parser-paper.pdf",  "examples/whatsapp_chat.txt"]

    loader = UnstructuredAPIFileLoader(
        file_paths=file_paths,
        api_key="FAKE_API_KEY",
        strategy="fast",
        mode="elements",
    )
    docs = loader.load()
```

2aa3754024 Check for single prompt in __call__ method of the BaseLLM class (#4892)
# Ensuring that users pass a single prompt when calling a LLM 

- This PR adds a check to the `__call__` method of the `BaseLLM` class
to ensure that it is called with a single prompt
- Raises a `ValueError` if users try to call a LLM with a list of prompt
and instructs them to use the `generate` method instead

## Why this could be useful

I stumbled across this by accident. I accidentally called the OpenAI LLM
with a list of prompts instead of a single string and still got a
result:

```
>>> from langchain.llms import OpenAI
>>> llm = OpenAI()
>>> llm(["Tell a joke"]*2)
"\n\nQ: Why don't scientists trust atoms?\nA: Because they make up everything!"
```

It might be better to catch such a scenario preventing unnecessary costs
and irritation for the user.

## Proposed behaviour

```
>>> from langchain.llms import OpenAI
>>> llm = OpenAI()
>>> llm(["Tell a joke"]*2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/marcus/Projects/langchain/langchain/llms/base.py", line 291, in __call__
    raise ValueError(
ValueError: Argument `prompt` is expected to be a single string, not a list. If you want to run the LLM on multiple prompts, use `generate` instead.

ddd595fe81 feature/4493 Improve Evernote Document Loader (#4577)
# Improve Evernote Document Loader

When exporting from Evernote you may export more than one note.
Currently the Evernote loader concatenates the content of all notes in
the export into a single document and only attaches the name of the
export file as metadata on the document.

This change ensures that each note is loaded as an independent document
and all available metadata on the note e.g. author, title, created,
updated are added as metadata on each document.

It also uses an existing optional dependency of `html2text` instead of
`pypandoc` to remove the need to download the pandoc application via
`download_pandoc()` to be able to use the `pypandoc` python bindings.

Fixes #4493

0ff59569dc Adds 'IN' metadata filter for pgvector for checking set presence (#4982)
# Adds "IN" metadata filter for pgvector to all checking for set
presence

PGVector currently supports metadata filters of the form:
```
{"filter": {"key": "value"}}
```
which will return documents where the "key" metadata field is equal to
"value".

This PR adds support for metadata filters of the form:
```
{"filter": {"key": { "IN" : ["list", "of", "values"]}}}
```

Other vector stores support this via an "$in" syntax. I chose to use
"IN" to match postgres' syntax, though happy to switch.
Tested locally with PGVector and ChatVectorDBChain.

06e524416c power bi api wrapper integration tests & bug fix (#4983)
# Powerbi API wrapper bug fix + integration tests

- Bug fix by removing `TYPE_CHECKING` in in utilities/powerbi.py
- Added integration test for power bi api in
utilities/test_powerbi_api.py
- Added integration test for power bi agent in
agent/test_powerbi_agent.py
- Edited .env.examples to help set up power bi related environment
variables
- Updated demo notebook with working code in
docs../examples/powerbi.ipynb - AzureOpenAI -> ChatOpenAI

Notes: 

Chat models (gpt3.5, gpt4) are much more capable than davinci at writing
DAX queries, so that is important to getting the agent to work properly.
Interestingly, gpt3.5-turbo needed the examples=DEFAULT_FEWSHOT_EXAMPLES
to write consistent DAX queries, so gpt4 seems necessary as the smart
llm.

Fixes #4325

## Before submitting

Azure-core and Azure-identity are necessary dependencies

check integration tests with the following:
`pytest tests/integration_tests/utilities/test_powerbi_api.py`
`pytest tests/integration_tests/agent/test_powerbi_agent.py`

You will need a power bi account with a dataset id + table name in order
to test. See .env.examples for details.

bf5a3c6dec Support Databricks in SQLDatabase (#4702)
This PR adds support for Databricks runtime and Databricks SQL by using
[Databricks SQL Connector for
Python](https://docs.databricks.com/dev-tools/python-sql-connector.html).
As a cloud data platform, accessing Databricks requires a URL as follows

`databricks://token:{api_token}@{hostname}?http_path={http_path}&catalog={catalog}&schema={schema}`.

**The URL is **complicated** and it may take users a while to figure it
out**. Since the fields `api_token`/`hostname`/`http_path` fields are
known in the Databricks notebook, I am proposing a new method
`from_databricks` to simplify the connection to Databricks.

## In Databricks Notebook
After changes, Databricks users only need to specify the `catalog` and
`schema` field when using langchain.

the output parser form chat conversational agent now raises
`OutputParserException` like the rest.

The `raise OutputParserExeption(...) from e` form also carries through
the original error details on what went wrong.

I added the `ValueError` as a base class to `OutputParserException` to
avoid breaking code that was relying on `ValueError` as a way to catch
exceptions from the agent. So catching ValuError still works. Not sure
if this is a good idea though ?

e2d7677526 docs: compound ecosystem and integrations (#4870)
# Docs: compound ecosystem and integrations

**Problem statement:** We have a big overlap between the
References/Integrations and Ecosystem/LongChain Ecosystem pages. It
confuses users. It creates a situation when new integration is added
only on one of these pages, which creates even more confusion.
- removed References/Integrations page (but move all its information
into the individual integration pages - in the next PR).
- renamed Ecosystem/LongChain Ecosystem into Integrations/Integrations.
I like the Ecosystem term. It is more generic and semantically richer
than the Integration term. But it mentally overloads users. The
`integration` term is more concrete.
UPDATE: after discussion, the Ecosystem is the term.
Ecosystem/Integrations is the page (in place of Ecosystem/LongChain
Ecosystem).

As a result, a user gets a single place to start with the individual
integration.

7642f2159c Add human message as input variable to chat agent prompt creation (#4542)
# Add human message as input variable to chat agent prompt creation

This PR adds human message and system message input to
`CHAT_ZERO_SHOT_REACT_DESCRIPTION` agent, similar to [conversational
chat
agent](7bcf238a1a/langchain/agents/conversational_chat/base.py (L64-L71)).

I met this issue trying to use `create_prompt` function when using the
[BabyAGI agent with tools
notebook](https://python.langchain.com/en/latest/use_cases/autonomous_agents/baby_agi_with_agent.html),
since BabyAGI uses “task” instead of “input” input variable. For normal
zero shot react agent this is fine because I can manually change the
suffix to “{input}/n/n{agent_scratchpad}” just like the notebook, but I
cannot do this with conversational chat agent, therefore blocking me to
use BabyAGI with chat zero shot agent.

I tested this in my own project
[Chrome-GPT](https://github.com/richardyc/Chrome-GPT) and this fix
worked.

c998569c8f docs: text splitters improvements (#4490)
#docs: text splitters improvements

Changes are only in the Jupyter notebooks.
- added links to the source packages and a short description of these
packages
- removed " Text Splitters" suffixes from the TOC elements (they made
the list of the text splitters messy)
- moved text splitters, based on the length function into a separate
list. They can be mixed with any classes from the "Text Splitters", so
it is a different classification.

But many use cases need to assign API keys dynamically, recently.

llm = OpenAI(openai_api_key="OPENAI_API_KEY")
```

## Before submitting
```bash
export OPENAI_API_KEY="..."

# Add generic document loader

* This PR adds a generic document loader which can assemble a loader
from a blob loader and a parser
* Adds a registry for parsers
* Populate registry with a default mimetype based parser


## Expected changes

- Parsing involves loading content via IO so can be sped up via:
  * Threading in sync
  * Async  
- The actual parsing logic may be computatinoally involved: may need to
figure out to add multi-processing support
- May want to add suffix based parser since suffixes are easier to
specify in comparison to mime types

## Before submitting

No notebooks yet, we first need to get a few of the basic parsers up
(prior to advertising the interface)

# Docs: improvements in the `retrievers/examples/` notebooks

Its primary purpose is to make the Jupyter notebook examples
**consistent** and more suitable for first-time viewers.
- add links to the integration source (if applicable) with a short
description of this source;
- removed `_retriever` suffix from the file names (where it existed) for
consistency;
- removed ` retriever` from the notebook title (where it existed) for
consistency;
- added code to install necessary Python package(s);
- added code to set up the necessary API Key.
- very small fixes in notebooks from other folders (for consistency):
  - docs/modules/indexes/vectorstores/examples/elasticsearch.ipynb
  - docs/modules/indexes/vectorstores/examples/pinecone.ipynb
  - docs/modules/models/llms/integrations/cohere.ipynb

6a9cdc43f5 Fix TypeError in Vectorstore Redis class methods (#4857)
# Fix TypeError in Vectorstore Redis class methods

This change resolves a TypeError that was raised when invoking the
`from_texts_return_keys` method from the `from_texts` method in the
`Redis` class. The error was due to the `cls` argument being passed
explicitly, which led to it being provided twice since it's also
implicitly passed in class methods. No relevant tests were added as the
issue appeared to be better suited for linters to catch proactively.

Changes:
- Removed `cls=cls` from the call to `from_texts_return_keys` in the
`from_texts` method.

# update qdrant docs to reflect the proper way to initialize Qdrant()
constructor

The [Qdrant
docs](https://python.langchain.com/en/latest/modules/indexes/vectorstores/examples/qdrant.html)
still contain an old reference for passing an `embedding_function` into
the constructor. This is no longer supported.

This PR updates the docs to reflect the proper way to initialize
`Qdrant()`

e90654f39b Added cleaning up the downloaded PDF files (#4601)
ArxivAPIWrapper searches and downloads PDFs to get related information.
But I found that it doesn't delete the downloaded file. The reason why
this is a problem is that a lot of PDF files remain on the server. For
example, one size is about 28M.
So, I added a delete line because it's too big to maintain on the
server.

# Clean up downloaded PDF files
- Changes: Added new line to delete downloaded file
- Background: To get the information on arXiv's paper, ArxivAPIWrapper
class downloads a PDF.
It's a natural approach, but the wrapper retains a lot of PDF files on
the server.
- Problem: One size of PDFs is about 28M. It's too big to maintain on a
small server like AWS.
- Dependency: import os

Thank you.

432421ffa5 [Fix][GenerativeAgent] Get the memory importance score from regex matched group (#4636)
# Get the memory importance score from regex matched group

In `GenerativeAgentMemory`, the `_score_memory_importance()` will make a
prompt to get a rating score. The prompt is:
```
        prompt = PromptTemplate.from_template(
            "On the scale of 1 to 10, where 1 is purely mundane"
            + " (e.g., brushing teeth, making bed) and 10 is"
            + " extremely poignant (e.g., a break up, college"
            + " acceptance), rate the likely poignancy of the"
            + " following piece of memory. Respond with a single integer."
            + "\nMemory: {memory_content}"
            + "\nRating: "
        )
```
For some LLM, it will respond with, for example, `Rating: 8`. Thus we
might want to get the score from the matched regex group.

bcce9a3a92 Fix age inconsistency in plan and execute Jupyter notebook example (#4814)
The current example in
https://python.langchain.com/en/latest/modules/agents/plan_and_execute.html
has inconsistent reasoning step (observing 28 years and thinking it's 26
years):

```
Observation: 28 years
Thought:Based on my search, Gigi Hadid's current age is 26 years old. 
Action:
{
  "action": "Final Answer",
  "action_input": "Gigi Hadid's current age is 26 years old."
}
```

Guessing this is model noise. Rerunning seems to give correct answer of
28 years.

# Fix DeepLake Overwrite Flag Issue

Fixes Issue #4682: essentially, setting overwrite to False in the
DeepLake constructor still triggers an overwrite, because the logic is
just checking for the presence of "overwrite" in kwargs. The fix is
simple--just add some checks to inspect if "overwrite" in kwargs AND
kwargs["overwrite"]==True.

Added a new test in
tests/integration_tests/vectorstores/test_deeplake.py to reflect the
desired behavior.

# Glossary
# Concepts
This is a collection of terminology commonly used when developing LLM applications.
These are concepts and terminology commonly used when developing LLM applications.
It contains reference to external papers or sources where the concept was first introduced,
as well as to places in LangChain where the concept is used.
## Chain of Thought Prompting
## Chain of Thought
A prompting technique used to encourage the model to generate a series of intermediate reasoning steps.
`Chain of Thought (CoT)` is a prompting technique used to encourage the model to generate a series of intermediate reasoning steps.
A less formal way to induce this behavior is to include “Lets think step-by-step” in the prompt.
Resources:
- [Chain-of-Thought Paper](https://arxiv.org/pdf/2201.11903.pdf)
- [Step-by-Step Paper](https://arxiv.org/abs/2112.00114)
## Action Plan Generation
A prompt usage that uses a language model to generate actions to take.
`Action Plan Generation` is a prompting technique that uses a language model to generate actions to take.
The results of these actions can then be fed back into the language model to generate a subsequent action.
Resources:
- [WebGPT Paper](https://arxiv.org/pdf/2112.09332.pdf)
- [SayCan Paper](https://say-can.github.io/assets/palm_saycan.pdf)
## ReAct Prompting
## ReAct
A prompting technique that combines Chain-of-Thought prompting with action plan generation.
`ReAct` is a prompting technique that combines Chain-of-Thought prompting with action plan generation.
This induces the to model to think about what action to take, then take it.

| **LangChain** is a framework for developing applications powered by language models. We believe that the most powerful and differentiated applications will not only call out to a language model, but will also be:
1. *Data-aware*: connect a language model to other sources of data
2. *Agentic*: allow a language model to interact with its environment
- *Be data-aware*: connect a language model to other sources of data
- *Be agentic*: allow a language model to interact with its environment
| The LangChain framework is designed around these principles.
The LangChain framework is designed with the above principles in mind.

Modules
-----------
There are several main modules that LangChain provides support for.
For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.
These modules are, in increasing order of complexity:
| These modules are the core abstractions which we view as the building blocks of any LLM-powered application.
For each module LangChain provides standard, extendable interfaces. LangChain also provides external integrations and even end-to-end implementations for off-the-shelf use.
- `Models <./modules/models.html>`_: The various model types and model integrations LangChain supports.
| The docs for each module contain quickstart examples, how-to guides, reference docs, and conceptual guides.
- `Prompts <./modules/prompts.html>`_: This includes prompt management, prompt optimization, and prompt serialization.
| The modules are (from least to most complex):
- `Memory <./modules/memory.html>`_: Memory is the concept of 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.
- `Models <./modules/models.html>`_: Supported model types and integrations.
- `Indexes <./modules/indexes.html>`_: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.
- `Prompts <./modules/prompts.html>`_: Prompt management, optimization, and serialization.
- `Chains <./modules/chains.html>`_: Chains go beyond just a single LLM call, and are 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.
- `Memory <./modules/memory.html>`_: Memory refers to state that is persisted between calls of a chain/agent.
- `Agents <./modules/agents.html>`_: 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.
- `Indexes <./modules/indexes.html>`_: Language models become much more powerful when combined with application-specific data - this module contains interfaces and integrations for loading, querying and updating external data.
- `Callbacks <./modules/callbacks/getting_started.html>`_: It can be difficult to track all that occurs inside a chain or agent - callbacks help add a level of observability and introspection.
- `Chains <./modules/chains.html>`_: Chains are structured sequences of calls (to an LLM or to a different utility).
- `Agents <./modules/agents.html>`_: An agent is a Chain in which an LLM, given a high-level directive and a set of tools, repeatedly decides an action, executes the action and observes the outcome until the high-level directive is complete.
- `Callbacks <./modules/callbacks/getting_started.html>`_: Callbacks let you log and stream the intermediate steps of any chain, making it easy to observe, debug, and evaluate the internals of an application.

Use Cases
----------
The above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.
| Best practices and built-in implementations for common LangChain use cases:
- `Autonomous Agents <./use_cases/autonomous_agents.html>`_: Autonomous agents are long running agents that take many steps in an attempt to accomplish an objective. Examples include AutoGPT and BabyAGI.
- `Autonomous Agents <./use_cases/autonomous_agents.html>`_: Autonomous agents are long-running agents that take many steps in an attempt to accomplish an objective. Examples include AutoGPT and BabyAGI.
- `Agent Simulations <./use_cases/agent_simulations.html>`_: Putting agents in a sandbox and observing how they interact with each other or to events can be an interesting way to observe their long-term memory abilities.
- `Agent Simulations <./use_cases/agent_simulations.html>`_: Putting agents in a sandbox and observing how they interact with each other and react to events can be an effective way to evaluate their long-range reasoning and planning abilities.
- `Personal Assistants <./use_cases/personal_assistants.html>`_: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.
- `Personal Assistants <./use_cases/personal_assistants.html>`_: One of the primary LangChain use cases. Personal assistants need to take actions, remember interactions, and have knowledge about your data.
- `Question Answering <./use_cases/question_answering.html>`_: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.
- `Question Answering <./use_cases/question_answering.html>`_: Another common LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.
- `Chatbots <./use_cases/chatbots.html>`_: Since language models are good at producing text, that makes them ideal for creating chatbots.
- `Chatbots <./use_cases/chatbots.html>`_: Language models love to chat, making this a very natural use of them.
- `Querying Tabular Data <./use_cases/tabular.html>`_: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.
- `Querying Tabular Data <./use_cases/tabular.html>`_: Recommended reading if you want to use language models to query structured data (CSVs, SQL, dataframes, etc).
- `Code Understanding <./use_cases/code.html>`_: If you want to understand how to use LLMs to query source code from github, you should read this page.
- `Code Understanding <./use_cases/code.html>`_: Recommended reading if you want to use language models to analyze code.
- `Interacting with APIs <./use_cases/apis.html>`_: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.
- `Interacting with APIs <./use_cases/apis.html>`_: Enabling language models to interact with APIs is extremely powerful. It gives them access to up-to-date information and allows them to take actions.
- `Extraction <./use_cases/extraction.html>`_: Extract structured information from text.
- `Summarization <./use_cases/summarization.html>`_: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.
- `Summarization <./use_cases/summarization.html>`_: Compressing longer documents. A type of Data-Augmented Generation.
- `Evaluation <./use_cases/evaluation.html>`_: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.
- `Evaluation <./use_cases/evaluation.html>`_: Generative models are hard to evaluate with traditional metrics. One promising approach is to use language models themselves to do the evaluation.

2. Add your documents (PDF, DOCX or DOC) and allow Docugami to ingest and cluster them into sets of similar documents, e.g. NDAs, Lease Agreements, and Service Agreements. There is no fixed set of document types supported by the system, the clusters created depend on your particular documents, and you can [change the docset assignments](https://help.docugami.com/home/working-with-the-doc-sets-view) later.
3. Create an access token via the Developer Playground for your workspace. Detailed instructions: https://help.docugami.com/home/docugami-api
4. Explore the Docugami API at https://api-docs.docugami.com/ to get a list of your processed docset IDs, or just the document IDs for a particular docset.

6. Use the DocugamiLoader as detailed in [this notebook](../modules/indexes/document_loaders/examples/docugami.ipynb), to get rich semantic chunks for your documents.
7. Optionally, build and publish one or more [reports or abstracts](https://help.docugami.com/home/reports). This helps Docugami improve the semantic XML with better tags based on your preferences, which are then added to the DocugamiLoader output as metadata. Use techniques like [self-querying retriever](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query_retriever.html) to do high accuracy Document QA.

# Psychic
This page covers how to use [Psychic](https://www.psychic.dev/) within LangChain.
## What is Psychic?
Psychic is a platform for integrating with your customers SaaS tools like Notion, Zendesk, Confluence, and Google Drive via OAuth and syncing documents from these applications to your SQL or vector database. You can think of it like Plaid for unstructured data. Psychic is easy to set up - you use it by importing the react library and configuring it with your Sidekick API key, which you can get from the [Psychic dashboard](https://dashboard.psychic.dev/). When your users connect their applications, you can view these connections from the dashboard and retrieve data using the server-side libraries.
## Quick start
1. Create an account in the [dashboard](https://dashboard.psychic.dev/).
2. Use the [react library](https://docs.psychic.dev/sidekick-link) to add the Psychic link modal to your frontend react app. Users will use this to connect their SaaS apps.
3. Once your user has created a connection, you can use the langchain PsychicLoader by following the [example notebook](../modules/indexes/document_loaders/examples/psychic.ipynb)
# Advantages vs Other Document Loaders
1. **Universal API:** Instead of building OAuth flows and learning the APIs for every SaaS app, you integrate Psychic once and leverage our universal API to retrieve data.
2. **Data Syncs:** Data in your customers' SaaS apps can get stale fast. With Psychic you can configure webhooks to keep your documents up to date on a daily or realtime basis.
3. **Simplified OAuth:** Psychic handles OAuth end-to-end so that you don't have to spend time creating OAuth clients for each integration, keeping access tokens fresh, and handling OAuth redirect logic.

@@ -17,7 +17,7 @@ At the moment, there are two main types of agents:
When should you use each one? Action Agents are more conventional, and good for small tasks.
For more complex or long running tasks, the initial planning step helps to maintain long term objectives and focus. However, that comes at the expense of generally more calls and higher latency.
These two agents are also not mutually exclusive - in fact, it is often best to have an Action Agent be in change of the execution for the Plan and Execute agent.
