Contribute to a repository you do NOT own or maintain (open source, an upstream you forked, another team). Use when opening or preparing a PR/patch to a foreign repo, or when the user mentions: contribute upstream, open-source PR, send a patch, fix in someone else's repo. NOT for your own/home repos — use the project's own pull-requests skill there.

Write or change a static-analysis / refactoring rule in the rector/symplify/Tomas ecosystem — a Rector rule, a PHPStan rule, or a symplify/phpstan-rules rule. Activate when: adding or modifying a rule, "write a rector rule", "add a phpstan rule", "new rule/sniff", or touching rules/ or src/Rules/.
