Business Feature Docs

EasyPlatform Business Feature Documentation

Generate comprehensive business feature documentation following the GOLD STANDARD template pattern.

GOLD STANDARD Reference: docs/features/README.ExampleFeature1.md (Example App) Template File: docs/templates/detailed-feature-docs-template.md

Output Structure

All documentation MUST be placed in the correct folder structure:

docs/
├── BUSINESS-FEATURES.md              # Master index (UPDATE if new module)
└── business-features/
    ├── {Module}/                     # Module folder
    │   ├── README.md                 # Complete module documentation
    │   ├── INDEX.md                  # Navigation hub
    │   ├── API-REFERENCE.md          # Endpoint documentation

    │   └── detailed-features/
    │       ├── README.{FeatureName}.md     # Deep dive (~1000 lines)
    │       └── README.{FeatureName}.ai.md  # AI companion (~300 lines)
    └── ...

MANDATORY 26-SECTION STRUCTURE

All feature documentation in detailed-features/ MUST follow this section order:

Phase 1: Module Detection & Context Gathering

Step 1.1: Identify Target Module

Determine which module the feature belongs to by:

1. User explicitly specifies module name
2. Feature name/domain implies module
3. Search codebase for feature-related entities/commands

Step 1.2: Read Existing Documentation

Before creating new docs, read existing structure:

1. Read docs/BUSINESS-FEATURES.md (master index)
2. Read docs/business-features/{Module}/INDEX.md (if exists)
3. Read docs/business-features/{Module}/README.md (if exists)
4. Identify what already exists vs what needs creation/update

Step 1.3: Codebase Analysis

Gather evidence from source code:

• Entities: src/Services/{Module}/{Module}.Domain/Entities/
• Commands: src/Services/{Module}/{Module}.Application/UseCaseCommands/
• Queries: src/Services/{Module}/{Module}.Application/UseCaseQueries/
• Controllers: src/Services/{Module}/{Module}.Service/Controllers/
• Frontend: src/Frontend/apps/playground-{module}/ or src/Frontend/libs/apps-domains/

Phase 2.5: AI Companion Generation

Generate AI-agent optimized companion file alongside the comprehensive documentation.

Output: docs/business-features/{Module}/detailed-features/README.{FeatureName}.ai.md Template: docs/templates/detailed-feature-docs-template.ai.md

AI Companion Structure (10 Sections, ~260 lines)

Compression Rules

1. Tables over prose - Convert paragraphs to table rows
2. Paths over descriptions - File:Line over "located in..."
3. Signatures over examples - { id: string } → { entity: Dto } over full code
4. Decisions over explanations - What to do, not why

AI Companion Quality Check

• File size ≤300 lines
• All file paths are exact and current
• API contracts include request/response shapes
• Business rules have evidence references
• Patterns section has ✅/❌ markers
• Evidence chain preserved from full doc

Phase 3: Master Index Update

After creating/updating module docs, update docs/BUSINESS-FEATURES.md:

1. Read current content
2. Verify module is listed in the "Detailed Module Documentation" table
3. Add link if missing:

   | **{Module}** | [Description] | [View Details](./business-features/{Module}/README.md) |
   

Anti-Hallucination Protocols

EVIDENCE_CHAIN_VALIDATION

• Every feature claim MUST have code reference with file path and line numbers
• Read actual source files before documenting
• Never assume behavior without code evidence

ACCURACY_CHECKPOINT

Before writing any documentation:

• "Have I read the actual code?"
• "Are my line number references accurate?"
• "Can I provide a code snippet as evidence?"
