Feature Request: Task Parallelization

[HadesArchitect]

Background

Currently, Kilo Code uses a stack-based sequential task execution model. When a task creates a subtask (using the new_task tool), the parent task pauses until the subtask completes. This limits productivity as only one task can be actively executed at a time.

Feature Description

Introduce task parallelization capability to allow multiple tasks to execute simultaneously. This would enable users to initiate background tasks while continuing to work on their main task without interruption.

Key Requirements

• Concurrent Task Execution: Allow parent tasks to spawn subtasks that run in parallel without blocking the parent
• Result Communication: Provide a mechanism for parallel tasks to communicate their results back to the parent task when complete
• Task Status Visibility: Enable users to see the status of all running tasks and switch between them

Benefits

• Improved Productivity: Users can continue working while waiting for resource-intensive operations
• Natural Workflow: Better represents real-world development processes where multiple operations often happen in parallel
• Resource Utilization: More efficient use of system resources and API bandwidth

Example Use Cases

• Generating multiple components simultaneously
• Running tests while continuing development
• Executing long-running commands while still being able to ask questions or work on other parts of the codebase
