Commit Messages Are Your Professional Legacy

You're three weeks at a new job. A production incident at 3 PM Thursday. The payment service returned HTTP 500 for 12 minutes. You dive into git log and find:

fix: fix things
WIP
asdf
updated stuff
lol
typo
DAMN IT

The last 40 commits are a cry for help. You find the culprit — a one-line timeout change buried in a 200-line diff titled "updated stuff" from someone who left eight months ago. 300ms instead of 30s. No explanation. No ticket number.

Your commit history is the only permanent record of your thinking. Bad commit messages are technical debt that compounds faster than anything else — because unlike bad code, which at least runs, bad commit messages are invisible until you need them.

The five-minute commit message rule:

• Subject line: WHAT changed (one sentence)


• Body: WHY it changed


• Reference: ticket, issue, or decision

git commit -m "Increase payment retry timeout from 300ms to 30s

The old 300ms timeout caused premature retries during peak load,
creating duplicate charge attempts. Downstream provider rate limit
kicks in after 5 req/s, our retry loop was sending 10/s.

Refs: #4821, incident-2026-07-03-payment-timeouts"

That's four lines. Sixty seconds. Saves someone forty-five minutes six months from now.

"A commit message is the last thing you'll ever say about a change. Make it worth the archaeology."
