 - **`OutputCapture`**: Buffers command output for redirection to files
 
 ### Modular Command Architecture
-The project now uses a fully modularized command architecture where each DOS command is implemented in its own file:
+The project uses a fully modularized command architecture with unified context management:
 
 - **`src/cmd/`**: Directory containing individual command implementations
-- **Command Pattern**: Each command implements an `eval()` method with consistent signature
+- **`CommandContext`**: Unified context struct containing allocator, I/O capture, and execution functions
+- **Command Pattern**: Each command implements `eval(command, ctx: CommandContext)` with consistent signature
 - **Type Safety**: Commands are strongly typed Zig structs with compile-time guarantees
 - **Shared Types**: Common types defined in `src/cmd/lib/types.zig` for consistency
+- **Clean Architecture**: All commands (Builtin, External, Redirect, Pipe) use the same modular pattern
