+#!/usr/bin/env bash
+# shannoncoat - run more than one claude desktop profile on mac.
+#
+# claude desktop app seems to keep everything important in one config directory,
+# so a different --user-data-dir gives a practically separate install.
+# and CLAUDE_CONFIG_DIR env var can isolate claude code sessions natively.
+# this script combines these to isolate both desktop sessions and the claude
+# code sessions they run.
+#
+# profiles are yaml files in ~/.shannoncoat:
+#   # ~/.shannoncoat/client1.yaml -> profile named "client1"
+#   paths:
+#     code: ~/work/client1/.claude/code
+#     desktop: ~/work/client1/.claude/desktop
+#
+# claude code inside the desktop app can run in some folder which already
+# defines a CLAUDE_CONFIG_DIR with direnv etc, that variable can be defined
+# this way to allow both individual and desktop sessions work properly:
+#   export CLAUDE_CONFIG_DIR="${CLAUDE_CONFIG_DIR:-$HOME/.claude}"
+#
+
