RALPH chart workflow

Copy this checklist and track your progress:

CopyProgress:
- [ ] Step 1: Parse task prompt
- [ ] Step 2: Resolve paths
- [ ] Step 3: Read templates
- [ ] Step 4: Load project knowledge
- [ ] Step 5: Analyze GATHERED_INFO
- [ ] Step 6: Generate RALPH chart
- [ ] Step 7: Write output

Step 1: Parse task prompt

Parse from task prompt:

• CONFIG: Project configuration (includes BASE_PATH)
• output_path: "tickets"
• output_filename: "ralph-chart.md"
• GATHERED_INFO: Git diff and file contents

Step 2: Resolve paths

Resolve paths:

• CONFIG.BASE_PATH required (error if missing: "CONFIG.BASE_PATHが未設定です")
• OUTPUT_DIR = CONFIG.BASE_PATH + "/" + output_path

Step 3: Read templates

Read templates (Handlebars format):

• ./templates/ralph-chart-template.md

Step 4: Load project knowledge

Run: python ~/.claude/scripts/resolve_knowledge.py --refs "${TICKET_PATH}/knowledge-refs.md" --workflow "/ui-test-design" --base "${CONFIG.BASE_PATH}"

• On success/partial: use knowledge[].content for Terminology and Specifications sections

Step 5: Analyze GATHERED_INFO

Analyze GATHERED_INFO:

• Identify purpose function (one chart per function)
• Extract Input factors from parameters, DTOs, API query params
• Extract State factors from conditional checks, entity status
• Extract Output factors from return types, exceptions, side effects
• Infer Noise factors from try-catch, timeouts, retry logic
• Infer Active Noise factors from validation, rate limiting, concurrency

Step 6: Generate RALPH chart

Generate RALPH chart document:

• Create ASCII structure diagram
• Build factor-level tables for all 5 categories
• Document constraints (invalid combinations)
• Include YAML structure data
• Add test design recommendation

Step 7: Write output

Write output to OUTPUT_DIR/output_filename.
