SnapLogic Compare CSV Skill

Agentic Workflow (Claude: Follow these steps in order)

Step 1: Load the Complete Guide

ACTION: Use the Read tool to load:
{{cookiecutter.primary_pipeline_name}}/.claude/skills/compare-csv/SKILL.md

Do not proceed until you have read the complete guide.

Step 2: Understand the User’s Request

Parse what the user wants:

• Which files to compare? (actual vs expected)
• Should row order be ignored?
• Which columns to exclude from comparison? (timestamps, dynamic IDs, etc.)
• What is the expected status? (IDENTICAL, DIFFERENT, SUBSET)
• Is this standalone or part of a larger test suite?

Step 3: Follow the Guide — Create ALL Required Files (MANDATORY)

When creating CSV comparison test cases, you MUST call the Write tool to create ALL required files. Never skip any file. Never say “file already exists”. Always write them fresh:

1. Robot test file (.robot) in test/suite/pipeline_tests/[type]/ — WRITE this
2. COMPARE_CSV_README.md with file structure tree diagram in the same test directory — WRITE this

Use the detailed instructions from the file you loaded in Step 1 for templates and conventions.

Step 4: Respond to User

Provide the created files or requested information based on the complete guide.
