Dev Secure Coding · slackwero bundle Use when writing or modifying application code in any language — endpoints, handlers, database queries, HTTP clients, file access, forms, config loading — and whenever adding or upgrading a dependency. Applies whenever code touches user input, credentials, SQL, shell commands, file paths, external URLs, or authentication, even if the request never mentions security. Also use before declaring code finished, to self-check what was written. Triggers on "create an endpoint", "add this library", "connect to this API", "save this to the database", "read this file", "add login". Complements the stack skills (dev-python-clean-code, golang-clean-code, dev-react-internal, dev-angular-internal) rather than replacing them.
