Dev Cheat Sheet

Quick-reference notes for things I always look up.

feat:Introduces a new feature.(MINOR)
fix:Patches a bug in existing code.(PATCH)
build:Changes to the build system or external dependencies.
chore:Routine maintenance; no production code change.
ci:CI/CD configuration files and scripts.
docs:Documentation changes only.
style:Formatting or whitespace — no logic changes.
refactor:Restructured code; no new feature or bug fix.
perf:A change that improves performance.
test:Adds or corrects tests.
