A surprising failure mode of agentic builds: the model sanitizes any shell pattern that loads secrets ($(cat ~/.supabase/token)), turning well-formed commands into syntactically broken ones like *** ~/.supabase/token). The workaround is to write a Python helper using os.path.expanduser so credentials are read at runtime — the sanitizer can't flag a literal os.environ load the same way. Type the real $(cat ~/.supabase/token) yourself in a separate terminal window, never copy from the model's output.
