# peepshow — statusline badge script for Claude Code.
# Prints a colored [PEEPSHOW] badge when the plugin is active. No newline, so
# it can be concatenated with other plugin statuslines (e.g. caveman).
#
# Suffix composition: [PEEPSHOW[|Ns][:<run-status>]]
#   Ns        → count of persistent auto-sinks configured in sinks.json
#   run-status → read from $PEEPSHOW_STATUS_FILE (defaults to
#                ~/.claude/.peepshow-last). Set by the CLI: "decoding:42%",
#                "5frm:scene:system", etc.
#
# Usage in settings.json:
#   "statusLine": { "type": "command", "command": "bash /path/peepshow-statusline.sh" }
