+# Shell Aliases
+
+Pi runs bash in non-interactive mode (`bash -c`), which doesn't expand aliases by default.
+
+To enable your shell aliases, add to `~/.pi/agent/settings.json`:
+
+```json
+{
+  "shellCommandPrefix": "shopt -s expand_aliases\neval \"$(grep '^alias ' ~/.zshrc)\""
+}
+```
+
+Adjust the path (`~/.zshrc`, `~/.bashrc`, etc.) to match your shell config.
