+# Implementation Plan: Rhai Integration for OS Module Functions
+
+## 1. Project Structure Changes
+
+We'll create a new directory structure for the Rhai integration:
+
+```
+src/
+├── rhai/
+│   ├── mod.rs         # Main module file for Rhai integration
+│   ├── os.rs          # OS module wrappers
+│   └── error.rs       # Error type conversions
+```
+
+## 2. Dependencies
+
+Add Rhai as a dependency in Cargo.toml:
+
+```toml
+[dependencies]
+# Existing dependencies...
+rhai = { version = "1.12.0", features = ["sync"] }
+```
+
+## 3. Implementation Steps
+
+### 3.1. Create Basic Module Structure
+
+1. Create the `src/rhai/mod.rs` file with:
+   - Module declarations
+   - A modular registration system
+   - Public exports
+
+2. Create the `src/rhai/error.rs` file with:
+   - Conversions from our custom error types to Rhai's `EvalAltResult`
+   - Helper functions for error handling
+
+### 3.2. Implement OS Module Wrappers
+
+Create the `src/rhai/os.rs` file with:
+
+1. Import necessary modules and types
+2. Create wrapper functions for each function in `src/os/fs.rs` and `src/os/download.rs`
+3. Implement a registration function specific to the OS module
+4. Expose error types to Rhai
+
+### 3.3. Update Main Library File
+
+Update `src/lib.rs` to expose the new Rhai module.
+
+## 4. Detailed Implementation
+
+### 4.1. Error Handling
+
+For each function that returns a `Result<T, E>` where `E` is one of our custom error types:
+
+1. Create a wrapper function that converts our error type to Rhai's `EvalAltResult`
+2. Register the error types with Rhai to allow for proper error handling in scripts
+
+### 4.2. Function Wrappers
+
+For each function in the OS module:
+
+1. Create a wrapper function with the same name
+2. Handle any necessary type conversions
+3. Convert error types to Rhai's error system
+4. Register the function with the Rhai engine
+
+### 4.3. Registration System
+
+Create a modular registration system:
+
+1. Implement a general `register` function that takes a Rhai engine
+2. Implement module-specific registration functions (e.g., `register_os_module`)
+3. Design the system to be extensible for future modules
+
+## 5. Implementation Flow Diagram
+
+```mermaid
+flowchart TD
+    A[Add Rhai dependency] --> B[Create directory structure]
+    B --> C[Implement error conversions]
+    C --> D[Implement OS module wrappers]
+    D --> E[Create registration system]
+    E --> F[Update lib.rs]
+    F --> G[Test the implementation]
+```
+
+## 6. Function Mapping
+
+Here's a mapping of the OS module functions to their Rhai wrappers:
+
+### File System Functions (from fs.rs)
+- `copy` → Wrap with error conversion
+- `exist` → Direct wrapper (returns bool)
+- `find_file` → Wrap with error conversion
+- `find_files` → Wrap with error conversion
+- `find_dir` → Wrap with error conversion
+- `find_dirs` → Wrap with error conversion
+- `delete` → Wrap with error conversion
+- `mkdir` → Wrap with error conversion
+- `file_size` → Wrap with error conversion
+- `rsync` → Wrap with error conversion
+
+### Download Functions (from download.rs)
+- `download` → Wrap with error conversion
+- `download_install` → Wrap with error conversion
+
+## 7. Error Type Handling
+
+We'll expose our custom error types to Rhai:
+
+1. Register `FsError` and `DownloadError` as custom types
+2. Implement proper error conversion to allow for detailed error handling in Rhai scripts
+3. Create helper functions to extract error information
+
+## 8. Testing Strategy
+
+1. Create unit tests for each wrapper function
+2. Create integration tests with sample Rhai scripts
+3. Test error handling scenarios
