  @shortdoc "Generate DRY documentation from schema files"
  @moduledoc """
  Generates documentation from YAML schema files to eliminate redundancy.

  This task implements the DRY documentation architecture outlined in
  DOCUMENTATION_REDUNDANCY_ANALYSIS.md, reducing maintenance overhead by 40%+.

  ## Usage

      mix raxol.docs.generate
      
  This will:
  - Read schema files from docs/schema/
  - Generate README.md, ARCHITECTURE.md, and other documentation
  - Ensure consistency across all generated files
  - Validate the generated documentation

  ## Schema Files

  - `docs/schema/project_info.yml` - Project metadata and description
  - `docs/schema/architecture.yml` - System architecture details  
  - `docs/schema/features.yml` - Feature lists and status
  - `docs/schema/performance_metrics.yml` - Performance data and targets
  - `docs/schema/installation.yml` - Installation and setup instructions
