Hermes · Drop Files In With @

Stop pasting code blocks. Type @ and a path instead. Hermes pulls the content in for you.

After this videoYou can now inject any file, folder, or URL without copy-paste.

Six @-reference types cover ~95% of the cases where you'd otherwise paste a blob: @file: for a file or a line range, @folder: for a directory tree, @url: for a web page, and @diff / @staged / @git:N for code review. Tab completion everywhere.

About these resources. One docs page contributed every fact in this video: the Context References feature page. It documents the full @-syntax catalog, line-range behavior, size limits, security blocklist, and tab-completion rules.
