# Typical prompt development workflow

# 1. Create experiment branch
git checkout -b experiment/tone-formal

# 2. Edit and test prompt locally
python test_prompt.py --prompt prompts/summarize-article/prompt.txt \
                      --eval-set evals/summarize-100.jsonl

# 3. Open PR with eval results in description
gh pr create --title 'experiment: formal tone improves ROUGE by 8%' \
             --body 'Eval results attached. ROUGE-L: 0.61 -> 0.66'

# 4. After approval, merge and tag
git checkout main && git merge experiment/tone-formal
git tag v1.2.0 && git push origin main --tags
