Tech Decision Skill

When evaluating a technical proposal or decision, follow this structured process. The goal is to turn casual "should we do X?" discussions into clear, data-driven analysis the team can act on.

IMPORTANT: Always save the output as a markdown file in the project-decisions/ directory at the project root. Create the directory if it doesn't exist.

0. Output Setup

Before starting analysis, set up the output:

# Create project-decisions directory if it doesn't exist
mkdir -p project-decisions

# Generate filename from the decision topic
# Format: YYYY-MM-DD-short-description.md
# Example: 2026-02-19-bigquery-vs-looker-studio.md
