GramFrame Implementation Plan

Overview

This document outlines the implementation plan for the GramFrame project, a JavaScript component that transforms HTML tables containing spectrogram images into interactive analysis tools. The plan is structured into phases aligned with the development tasks outlined in the project documentation.

Agent Roles

This project utilizes two primary agent roles within the Agentic Project Management (APM) framework:

• Implementation Agent: Responsible for developing features according to specifications
• Testing Agent: Responsible for creating test specifications and verifying implementation quality

For a detailed description of the Testing Agent's role and the project's testing strategy, refer to Testing-Strategy.md.

Testing Philosophy

This project follows a comprehensive testing approach to ensure quality and prevent regressions:

• Test-Driven Development: Tests will be written before implementation to guide development
• Unit and Integration Testing: Each component will have both unit tests and integration tests
• Test Coverage: No task is considered complete until it has adequate test coverage
• Continuous Testing: Tests will be run after each significant change to catch regressions early

Memory Bank Structure

This project will use a directory-based Memory Bank located at /Memory/. This structure was chosen due to:

• Multiple distinct phases with different functionality areas
• Need to organize test results by feature
• Better organization of implementation details by component

Timeline Estimation

• Phase 1: 2-3 days (increased to account for test-first development)
• Phase 2: 4-5 days (increased to account for comprehensive testing of visual elements)
• Phase 3: 3-4 days (increased to account for interaction testing complexity)
• Phase 4: 4-6 days (increased to account for mode-specific testing)
• Phase 5: 3-4 days (increased to account for cross-browser testing and final QA)

Total estimated time: 16-22 days

Note: The timeline has been adjusted to account for the comprehensive testing approach. While this increases the initial development time, it will reduce debugging and maintenance time in the long run by catching issues earlier in the development process.

Success Criteria

1. All functionality specified in the Functional Specification is implemented
2. Component correctly transforms tables with class "gram-config" into interactive tools
3. All two modes (Analysis, Doppler) function as specified
4. Comprehensive test coverage with Playwright
5. Clean, maintainable codebase with proper documentation
6. No build step required for end users - just include the script
