You know the feeling. You run git blame, expecting to understand why a line of code exists. Instead, you see “fix”. Or “update”. Or worse, nothing. Your blood pressure rises. You’ve just lost 20 minutes of your life.
This isn’t a minor annoyance. It’s a silent tax on every developer who touches your code. And it’s entirely preventable.
Here’s the brutal truth: A terse commit message is not efficiency. It’s technical debt, masquerading as speed.
We’ve all been there. You’re in the flow, cranking out code. The last thing you want to do is write a paragraph about what you just changed. So you type git commit -m "fix bug" and move on. Feels productive, right? Wrong.
Every time you do that, you’re stealing from your future self. And from every teammate who comes after you. Your future self is not a detective. Don’t make them play one.
Let me tell you about a project I worked on. The most senior developer there was a wizard. His code was elegant, his logic flawless. But his commit messages were one-word wonders. “Fix.” “Update.” “Change.” We spent hours reverse-engineering his reasoning. He was brilliant, but his commit messages made him a liability. The team’s velocity dropped every time we had to touch his code.
This is the hidden cost of bad commit messages. They don’t just waste time — they erode trust. When you see a vague message, you start questioning the author’s intent. Was this a quick hack? A deliberate design decision? A mistake? You have to dig through diffs, check other files, possibly run the code. All because someone couldn’t spare 30 seconds to write a clear sentence.
Now, I’m not saying every commit needs a novel. But there’s a middle ground between “fix” and a full essay. The best commit messages follow a simple formula: What changed + Why it changed. That’s it. The “why” is the golden nugget — it tells your future self (or your teammate) the reasoning behind the change. It turns a log entry into a piece of history.
Think about it: code tells you what the system does. The commit message tells you why it does it that way. Without the “why,” you’re flying blind. Code explains the present. A good commit message explains the past.
So take a side. Stop pretending that speed is more important than clarity. Stop writing “update” and start writing commit messages that respect the time of everyone who reads them. Your future self will thank you. Your teammates will thank you. And your codebase will become a place of understanding, not frustration.
Write a commit message that your future self would thank you for. Or prepare to keep paying the price.
FAQ
Q: But I'm the only one working on this project. Do I really need to write detailed commit messages?
A: Yes. Your future self is the most important collaborator you'll ever have. In six months, you won't remember why you made that change. A clear commit message saves you hours of digging through your own code.
Q: What's the practical first step to improving my commit messages?
A: Start with one rule: always include the reason for the change. For example, instead of 'Fix login bug', write 'Fix login bug: token validation was missing for OAuth redirects'. Use the imperative mood, keep the subject under 50 characters, and add a blank line before the body.
Q: Aren't commit messages just overhead? I want to ship code fast.
A: Speed without context is a false economy. Every minute you save by writing 'fix' today costs you or someone else ten minutes tomorrow. Good commit messages are an investment, not a tax. The best developers don't write the fastest code — they write the clearest history.
