# src/interfaces/command-finder.ts @source-hash: d4247b735492e106 @generated: 2026-02-10T00:41:43Z ## Purpose TypeScript interface and error class for system command resolution functionality. Provides a contract for finding executable commands in the system PATH and handling command resolution failures. ## Key Components ### CommandFinder Interface (L4-12) - **Purpose**: Contract for command resolution implementations - **Method**: `find(command: string): Promise<string>` (L11) - Asynchronously resolves command name to full executable path - Throws `CommandNotFoundError` when command not found in PATH - Returns Promise<string> containing absolute path to executable ### CommandNotFoundError Class (L17-22) - **Purpose**: Specialized error for command resolution failures - **Extends**: Built-in Error class - **Properties**: - `command: string` (L18) - readonly property storing the failed command name - **Constructor** (L18-21): Sets error message format and error name for proper error identification ## Architecture Notes - Interface follows async pattern (Promise-based) for potential I/O operations - Error class uses readonly property pattern for immutable command reference - Clean separation of concerns: interface defines contract, error class handles failure cases - Designed for dependency injection pattern (interface-based)
