+# Story 269: @ file references in web UI chat input
+
+## User Story
+
+As a user chatting in the web UI, I want to type @ to get an autocomplete overlay listing project files, so that I can reference specific files in my messages the same way Zed and Claude Code do.
+
+## Acceptance Criteria
+
+- [ ] Typing @ in the chat input triggers a file picker overlay
+- [ ] Overlay searches project files with fuzzy matching as the user types after @
+- [ ] Selecting a file inserts a reference into the message (e.g. @path/to/file.rs)
+- [ ] The referenced file contents are included as context when the message is sent to the LLM
+- [ ] Overlay is dismissable with Escape
+- [ ] Multiple @ references can be used in a single message
+
+## Out of Scope
+
+- TBD
