+    Synopsis:  agy [args...]
+    Wrapper for the agy Antigravity AI CLI. Before launching, delegates to
+    agents-init --agents to ensure AGENTS/ is scaffolded and CLAUDE.md is
+    symlinked to AGENTS/AGENTS.md in the current project, then forwards all
+    arguments verbatim to the real agy binary. Command shadow (C1): when
+    __fish_config_op_aliases (or the master) is disabled, the call is
+    passed through to the real agy binary unchanged.
