# An Adeptus Mechanicus status line for Claude Code.
# Your context window is the machine spirit's soul; as it fills the Warp
# bleeds in and heresy rises. Purge with /compact to sanctify the cogitator.
#
# Reads Claude Code session JSON on stdin, prints two sanctified lines.
# Requires: jq. Degrades gracefully when fields are null/absent.
