Merge branch 'feat/ibm-memory' of https://github.com/joaomdmoura/crewAI into feat/ibm-memory

This commit replaces .netrc with uv environment variables for installing
tools from private repositories. To store credentials, I created a new
and reusable settings file for the CLI in
`$HOME/.config/crewai/settings.json`.

The issue with .netrc files is that they are applied system-wide and are
scoped by hostname, meaning we can't differentiate tool repositories
requests from regular requests to CrewAI's API.

+### Adding Additional Crews Using the CLI
+
+Once you have created your initial flow, you can easily add additional crews to your project using the CLI. This allows you to expand your flow's capabilities by integrating new crews without starting from scratch.
+
+To add a new crew to your existing flow, use the following command:
+
+```bash
+crewai flow add-crew <crew_name>
+```
+
+This command will create a new directory for your crew within the `crews` folder of your flow project. It will include the necessary configuration files and a crew definition file, similar to the initial setup.
+
+#### Folder Structure
+
+After adding a new crew, your folder structure will look like this:
+
+name_of_flow/
+├── crews/
+│   ├── poem_crew/
+│   │   ├── config/
+│   │   │   ├── agents.yaml
+│   │   │   └── tasks.yaml
+│   │   └── poem_crew.py
+│   └── name_of_crew/
+│       ├── config/
+│       │   ├── agents.yaml
+│       │   └── tasks.yaml
+│       └── name_of_crew.py
+
+You can then customize the `agents.yaml` and `tasks.yaml` files to define the agents and tasks for your new crew. The `name_of_crew.py` file will contain the crew's logic, which you can modify to suit your needs.
+
+By using the CLI to add additional crews, you can efficiently build complex AI workflows that leverage multiple crews working together.

Whether you choose to use the `plot()` method or the command line, generating plots will provide you with a visual representation of your workflows, aiding in both development and presentation.
+## Advanced
+
+In this section, we explore more complex use cases of CrewAI Flows, starting with a self-evaluation loop. This pattern is crucial for developing AI systems that can iteratively improve their outputs through feedback.
+
+### 1) Self-Evaluation Loop
+
+The self-evaluation loop is a powerful pattern that allows AI workflows to automatically assess and refine their outputs. This example demonstrates how to set up a flow that generates content, evaluates it, and iterates based on feedback until the desired quality is achieved.
+
+#### Overview
+
+The self-evaluation loop involves two main Crews:
+
+1. **ShakespeareanXPostCrew**: Generates a Shakespearean-style post on a given topic.
+2. **XPostReviewCrew**: Evaluates the generated post, providing feedback on its validity and quality.
+
+The process iterates until the post meets the criteria or a maximum retry limit is reached. This approach ensures high-quality outputs through iterative refinement.
+
+#### Importance
+
+This pattern is essential for building robust AI systems that can adapt and improve over time. By automating the evaluation and feedback loop, developers can ensure that their AI workflows produce reliable and high-quality results.
+
+#### Main Code Highlights
+
+Below is the `main.py` file for the self-evaluation loop flow:
+
+```python
+from typing import Optional
+from crewai.flow.flow import Flow, listen, router, start
+from pydantic import BaseModel
+from self_evaluation_loop_flow.crews.shakespeare_crew.shakespeare_crew import (
+    ShakespeareanXPostCrew,

+    feedback: Optional[str] = None
+    valid: bool = False
+    retry_count: int = 0
+
+class ShakespeareXPostFlow(Flow[ShakespeareXPostFlowState]):
+
+    @start("retry")
+    def generate_shakespeare_x_post(self):
+        print("Generating Shakespearean X post")
+        topic = "Flying cars"
+        result = (
+            ShakespeareanXPostCrew()
+            .crew()
+            .kickoff(inputs={"topic": topic, "feedback": self.state.feedback})
+        )
+        print("X post generated", result.raw)
+        self.state.x_post = result.raw
+
+    @router(generate_shakespeare_x_post)
+    def evaluate_x_post(self):
+        if self.state.retry_count > 3:
+            return "max_retry_exceeded"
+        result = XPostReviewCrew().crew().kickoff(inputs={"x_post": self.state.x_post})
+        self.state.valid = result["valid"]
+        self.state.feedback = result["feedback"]
+        print("valid", self.state.valid)
+        print("feedback", self.state.feedback)
+        self.state.retry_count += 1
+        if self.state.valid:
+            return "complete"
+        return "retry"
+
+    @listen("complete")
+    def save_result(self):
+        print("X post is valid")
+        print("X post:", self.state.x_post)
+        with open("x_post.txt", "w") as file:
+            file.write(self.state.x_post)
+
+    @listen("max_retry_exceeded")
+    def max_retry_exceeded_exit(self):
+        print("Max retry count exceeded")
+        print("X post:", self.state.x_post)
+        print("Feedback:", self.state.feedback)
+
+def kickoff():
+    shakespeare_flow = ShakespeareXPostFlow()
+    shakespeare_flow.kickoff()
+
+def plot():
+    shakespeare_flow = ShakespeareXPostFlow()
+    shakespeare_flow.plot()
+
+if __name__ == "__main__":
+    kickoff()
+```
+
+#### Code Highlights
+
+- **Retry Mechanism**: The flow uses a retry mechanism to regenerate the post if it doesn't meet the criteria, up to a maximum of three retries.
+- **Feedback Loop**: Feedback from the `XPostReviewCrew` is used to refine the post iteratively.
+- **State Management**: The flow maintains state using a Pydantic model, ensuring type safety and clarity.
