+# cc() tmux alias: auto-launch Claude with nesting support
+
+## Context
+
+Cal's `~/.zshrc` has a `cc()` function for quickly launching Claude Code inside a named tmux session.
+
+## Final Implementation
+
+```zsh
+cc() {
+  local name="${1:-$(basename $PWD)}"
+  if [ -n "$TMUX" ]; then
+    tmux new -ds "$name" "claude" 2>/dev/null || tmux switch-client -t "$name"
+    tmux switch-client -t "$name"
+  else
+    tmux new -s "$name" -A "claude"
+  fi
+}
+```
+
+## Key Behaviors
+
+- Auto-names session from current directory basename if no argument given
+- Launches `claude` automatically inside the new session
+- If already inside tmux (`$TMUX` is set): creates a detached session and switches to it, avoiding nested tmux
+- If not in tmux: creates or attaches (`-A`) to the named session
+- The `2>/dev/null || switch-client` pattern handles the case where the session already exists
+
+## Notes
+
+- Cal's terminal (Warp or similar) may auto-start tmux on login, so the nesting check is important in practice
+- `cc project-name` overrides the auto-naming behavior
