# bb-peek — look at a page before you touch it. Read only.
#
# Matt (2026-10-23): "I filled out TruePeopleSearch and hit send and it okayed it.
# Now you didn't recognize that on the screen and you're doing it again."
# Run this BEFORE every step on a page the human might have touched. For every
# open tab that matches it prints the current URL, title, the start of the visible
# text, the form fields that hold something (passwords and card numbers masked),
# and whether the human is working in it right now. Tabs the human opened himself
# match too. It never reloads, focuses, navigates or types; nothing on his screen
# changes.
#
#   bb-peek <owner|url-substring|target-id> [chars]

# Exit 0 found something · 3 nothing matched · 1 error / broker down.
