Compatibility and portability checkers for developers — "will this break somewhere else, and why?"

How YAML means something different under 1.1 vs 1.2 rules.
Date String Portability Checker
Checks whether a date/time string is unambiguous and portable across runtimes.

Finds .env values that behave differently across Node's dotenv, Docker/Docker Compose and POSIX shell sourcing.
Regex Portability Checker
Checks whether a regular expression will work the same way in Python and PCRE-family engines.
SQL Identifier Portability Checker
Checks a table/column name against reserved words and quoting rules across databases.
YAML Cross-Runtime Preflight
Checks whether YAML will behave consistently across CI, Docker Compose, Kubernetes and more.
