Manifest Generation Task

Objective

Create and maintain the isaac_manifest.json configuration file that serves as the central definition for cross-platform installer generation, incorporating project analysis results and user customizations.

Task Overview

This task transforms project analysis results into a structured, comprehensive manifest file that defines all aspects of the installation process, including dependencies, configuration parameters, target platforms, and installation steps.

Process Steps

1. Manifest Structure Creation

Purpose: Establish the foundational structure of the isaac_manifest.json file

Actions:

• Initialize manifest with project metadata (name, version, description)

• Create technology stack section from project analysis results

• Establish dependency categories (runtime, system, development)

• Define configurable parameters structure with validation rules

• Set up target platform specifications

• Create installation steps framework

Output: Basic manifest structure with all required sections

2. Project Analysis Integration

Purpose: Populate manifest with data from project scanning results

Actions:

• Import detected technology stack information

• Map identified dependencies to manifest dependency structure

• Convert discovered configuration parameters to manifest format

• Integrate platform compatibility assessment results

• Import service and infrastructure requirements

• Validate imported data for completeness and accuracy

Output: Manifest populated with project-specific data

3. Platform-Specific Configuration

Purpose: Define platform-specific variations and requirements

Actions:

• Configure platform-specific dependency installation commands

• Define architecture-specific requirements (x64, ARM64, etc.)

• Set up platform-specific file paths and directory structures

• Configure service management approaches per platform

• Define platform-specific validation and testing procedures

• Establish platform-specific error handling strategies

Output: Complete platform configuration matrix

4. Interactive Parameter Definition

Purpose: Define user-configurable parameters with validation and defaults

Actions:

• Categorize configuration parameters by type and importance

• Define validation rules and input constraints

• Set appropriate default values based on common usage patterns

• Create parameter dependencies and conditional logic

• Define parameter grouping for organized user interaction

• Establish parameter documentation and help text

Output: Comprehensive parameter configuration system

5. Installation Step Orchestration

Purpose: Define the complete installation workflow with platform variations

Actions:

• Break down installation into logical, atomic steps

• Define step dependencies and execution order

• Create platform-specific command variations for each step

• Establish validation criteria for each installation step

• Define rollback procedures for failed steps

• Create progress tracking and user feedback mechanisms

Output: Complete installation workflow definition
