Okay so. Story time. Grab a coffee; this one's got a body count.
A few months back I got assigned a "small fix" on a payment reconciliation service. Small fix. That's what the ticket said. I need that on record before I tell you what happened next, because I want you to fully feel how personally I take that betrayal.
First file I open has a function called handlePayment2. Not handlePaymentV2. Not handlePaymentUpdated. Just 2. Like someone typed it out, looked at it, and thought, "Yeah, that's a professional software artifact," and then went to lunch. And it's sitting right next to handlePayment, which is STILL being called in three other places. Nobody deleted the original. It's just there. Both of them. Living together. Co-parenting the payment flow like a divorced couple who still share a group chat.
Zero comments anywhere in the file. Not one. I scrolled 400 lines and found exactly one piece of human text in the whole thing: // TODO fix this, dated 2022. Fix what. FIX WHAT, my guy. That's not a comment, that's a cry for help mailed to nobody.
This is when I realized the whole ordeal was giving me full Death Note energy — except instead of L calmly deducing a serial killer's identity from crumbs of evidence, it was just me, at 11pm, trying to deduce why a boolean exists using nothing but vibes and rage.
The Investigation Begins (Send Help)
Naturally I did the thing we all do when betrayed by silence: I opened git blame like it owed me money.
git blame on a codebase like this is a treasure map where X marks the spot, except the X is a commit from a user called temp-fix-do-not-merge who does not exist anymore, possibly never existed, possibly ascended. The treasure itself was a config flag called useNewLogic, which — plot twist — is neither new, nor optional, nor logic anyone currently understands. I spent two hours confirming the "old" path had been fully dead since 2023. Nobody deleted it. It's just sitting there, radioactive, feared by all, touched by none.
Big Frieren energy, honestly. A thousand-year-old elf mage carrying memories nobody else is even alive to share anymore. That's useNewLogic. It has seen wars. It remembers the Great Migration of 2023 that literally no one currently employed was present for.
The commit messages offered zero comfort. Real messages, paraphrased slightly so I don't doxx my former coworkers: "fix bug." "update per request." "changes." And then one, glorious, unhinged entry that just said: "idk." Lowercase. No period. A confession dressed up as documentation.
You inherit the code. You do not inherit the two Slack threads and one hallway conversation where the actual reasoning lived and died. That context left the building the day the original dev did, and there is no jutsu, no summoning scroll, no Dragon Ball wish that brings it back. I checked. I would not lie to you about something this important.
Why This Happens to Literally Everyone, Not Just Cursed People
I used to think uncommented codebases were a "lazy dev" problem. Wrong. I've met genuinely sharp, careful engineers who still leave behind absolute crime scenes, because it was never about laziness. It's about:
The deadline was real, the comment was not. Three hours before launch, nobody's thinking "how will this read to a confused stranger in 2026." They're thinking "please, for the love of god, just work." Comments die first in every crunch, on every team, in every universe including several I haven't worked on yet.
It felt obvious while you were inside it. The sneakiest one. Deep in a problem, your brain holds the whole context loaded, so everything looks self-explanatory — right up until that context evaporates and future-you is left staring at your own code like it's written in a language you almost speak.
Nobody ever got promoted for a great docstring. Ship the feature, get the Slack praise emoji. Explain the tradeoff clearly for whoever comes next? Silence. Not even future-you says thank you, and future-you is the one who needed it most.
Deleting dead code takes more nerve than writing new code. handlePayment2 exists because deleting handlePayment means someone has to be SURE, professionally, put-your-name-on-the-commit sure, that nothing depends on it. Way easier to slap a 2 on it and back away slowly. I say this with love: I have also been the guy who added the 2. We contain multitudes.
What Actually Changed For Me After This
I'm not going to pretend I became a documentation monk overnight, glowing with the wisdom of a thousand clean commits. But a few things genuinely stuck:
I started writing down the archaeology as I did it, not after, because "after" never comes. The second I confirmed something was dead, I left a comment saying so — confirmed dead as of this date, verified via logs, here's exactly how. Whoever comes next doesn't have to redo my two hours of suffering. Let my pain be their shortcut.
I stopped refactoring and understanding at the same time, because that's how you delete the one line holding the entire building up. Understand first, in a throwaway branch. Refactor second, once you actually know what's load-bearing and what's decorative.
I started assuming every "temporary" fix is permanent, because it always, always is. If it's survived longer than a sprint, it has tenure now. Respect the tenure.
And weirdly, I got a lot more sympathetic to whoever wrote the original mess. They weren't careless — they were a person, under a deadline, doing their best with the time they had. Same as me right now, quietly leaving behind my own future crime scene for someone else to git blame in 2027.
Your Turn, Don't Be Shy
I refuse to believe I'm the only one with a story like this. So:
What's the worst codebase you've ever inherited? What's the most deranged commit message you've personally witnessed with your own two eyes? And — deep breath — if a stranger opened your code from a year ago right now, zero context, cold read, would they curse your name, or would you actually be fine?
Asking for a friend. The friend is me. I already know the answer and I am choosing to grow from it.
