Requirements Language

Specifications use the standard RFC 2119 keywords to indicate requirement levels:

  • MUST: Absolute requirement
  • MUST NOT: Absolute prohibition
  • SHOULD: Recommended requirement
  • SHOULD NOT: Recommended prohibition
  • MAY: Optional feature

Using These Specifications

For Developers

  • Read the relevant specification before implementing changes
  • Ensure your implementation meets all MUST requirements
  • Consider SHOULD recommendations for best practices
  • Update specifications when adding new features or changing behavior

For Code Reviewers

  • Reference specifications when reviewing changes
  • Verify that implementations match documented requirements
  • Check that error handling meets specification standards
  • Ensure security requirements are met

For Testers

  • Create test cases based on MUST requirements
  • Test edge cases and error conditions
  • Verify that all formats are handled correctly
  • Check cross-browser compatibility where specified

Specification Structure

Each specification follows a consistent structure:

  1. Overview: High-level description of the feature
  2. Requirements: Detailed requirements using MUST/SHOULD/MAY
  3. API/Interface: Function signatures and data structures where applicable
  4. Error Handling: How errors should be handled
  5. Security: Security considerations
  6. Performance: Performance requirements

Keeping Specifications Updated

Specifications should be updated when:

  • New features are added
  • Existing behavior changes
  • New platforms are supported
  • Security requirements evolve
  • Performance characteristics change

Architecture Overview

The application follows a modular architecture:

App (State Management)
├── FileHandler (File Import)
│   └── Parsers (Conversation Parsing)
├── Storage (IndexedDB)
├── Sidebar (Conversation List UI)
│   └── Markdown (Markdown Rendering)
└── ChatView (Message Display UI)
    ├── Markdown (Markdown Rendering)
    └── Platform URLs (Continue Conversation)

Data flows through the system as follows:

  1. Import: FileHandler → Parsers → AppState
  2. Storage: AppState ↔ Storage (IndexedDB)
  3. Display: AppState → Sidebar/ChatView
  4. Export: AppState → Export Module → File Download
