Mask PII in-line. $ARGUMENTS is the raw user text — pass it verbatim, no escaping or quoting required (the heredoc below handles every shell metacharacter, newline, quote, and paren safely):
ZGPU_TEXT=$(cat <<'ZGPU_END_OF_INPUT'
$ARGUMENTS
ZGPU_END_OF_INPUT
)
zerogpu redact_pii "$ZGPU_TEXT"
Output is the original text with PII spans replaced by [LABEL] placeholders. To extract (not mask) PII, use extract-pii instead.
Savings note: only if the command output literally contains a line starting with 💰 ZeroGPU savings, append that exact line, unchanged, as the last line of your reply. If no such line is present, say nothing about savings.
