The **Plan** feature is a sophisticated system designed to break down high-level user requests into manageable,
actionable tasks. It leverages OpenAI's capabilities to automate task planning, execution, and management, ensuring
efficient workflow and seamless integration with existing systems.
---
## **Features Overview**
* **Dynamic Task Breakdown:** Automatically decompose user requests into smaller tasks with defined dependencies.
* **Task Execution:** Execute tasks such as code modifications, running shell commands, conducting code reviews, and
more.
* **Dependency Management:** Visualize and manage task dependencies using Mermaid diagrams.
* **Asynchronous Processing:** Execute tasks concurrently where possible, respecting dependencies to optimize
performance.
* **Customizable Settings:** Tailor the planning and execution process through configurable settings.
* **Extensible Architecture:** Easily add new task types and extend existing functionalities to fit unique requirements.
---
## **User Guide**
### **Accessing the Plan Feature**
To utilize the Plan feature, navigate to the application interface where task planning and management functionalities
are exposed. This could be within a web UI or another integrated platform provided by your organization.
### **Creating and Managing Plans**
1. **Initiate a New Plan:**
* Enter your high-level request or goal into the provided input field.
* For example: "Set up a new React project with TypeScript and implement authentication."
2. **Task Breakdown:**
* The system will analyze your request and automatically generate a list of actionable tasks.
* Each task will include details such as task type, description, dependencies, input files, and output files.
3. **Review Generated Tasks:**
* Examine the generated tasks to ensure they align with your expectations.
* Modify or adjust tasks if necessary through the interface (if supported).
4. **Execute the Plan:**
* Start the execution process, which will carry out each task based on the defined dependencies.
* Monitor the progress through real-time updates and logs.
### **Understanding Task Dependencies**
* **Visual Representation:**
* The Plan feature utilizes Mermaid to render task dependency graphs.
* Access the "Task Dependency Graph" section to visualize how tasks interrelate.
* **Interpreting the Graph:**
* Nodes represent individual tasks.
* Arrows indicate dependencies; a task will only execute after its dependent tasks are completed.
* Styles (e.g., color-coding) indicate the state of each task (Pending, In Progress, Completed).
### **Viewing Execution Logs**
* **Accessing Logs:**
* Execution logs are automatically generated and can be accessed through the UI.
* Logs provide detailed information about each task's execution, including API interactions and any errors
encountered.
* **Log Files:**
* Logs are stored in the `.logs` directory within your working directory.
* Each task execution generates a unique log file for traceability.

* **Solution:** Review the task definitions to ensure that dependencies are acyclic. Modify task dependencies to
eliminate cycles.
2. **Unknown Task Type Error:**
* **Issue:** An error stating "Unknown task type" is encountered.
* **Solution:** Ensure that all custom task types are properly defined and registered in `TaskType.kt`.
3. **API Errors:**
* **Issue:** Failures in API interactions during task execution.
* **Solution:** Check API credentials, network connectivity, and API service status. Review logs for detailed error
messages.
4. **File Reading Errors:**
* **Issue:** Errors while reading input or output files.
* **Solution:** Verify file paths, permissions, and the existence of the specified files.
5. **Task Execution Failures:**
* **Issue:** Individual tasks fail during execution.
* **Solution:** Examine the logs associated with the failed task for error details. Ensure that task configurations are
correct and dependencies are met.
