Use bash (git) to calculate DORA engineering metrics.

Deployment Frequency

bash

# Tags/releases in last 30 days
git tag --sort=-creatordate --format='%(creatordate:short) %(refname:short)' | head -30
git log --since="30 days ago" --oneline --merges --first-parent main | wc -l

Lead Time for Changes

bash

# Time from first commit to merge (for recent PRs)
gh pr list -R OWNER/REPO --state merged --limit 20 --json number,createdAt,mergedAt,title

Change Failure Rate

bash

# Reverts and hotfixes in last 30 days
git log --since="30 days ago" --oneline --grep="revert\|hotfix\|rollback" -i | wc -l
# vs total deploys
git tag --sort=-creatordate --after="30 days ago" | wc -l

Mean Time to Recovery (MTTR)

bash

# Time between bug report and fix merge
gh issue list -R OWNER/REPO --state closed --label "bug" --search "closed:>=$(date -d '30 days ago' +%Y-%m-%d)" --json number,createdAt,closedAt --limit 20

MTTR	< 1 hour	< 1 day	< 1 week	6 months

Tips

•Track over time using memory_save for historical data
•Compare across sprints for improvement trends
•Use git tags consistently for accurate deployment frequency
