msu-statusline-config

One file holds every setting: ${CLAUDE_CONFIG_DIR:-$HOME/.claude}/msu-statusline.conf, written as KEY=value, one per line. A # at the start of a value or after whitespace starts a comment; an embedded # such as LABEL=C#Build is literal. Newlines and comment-opening # cannot be represented inside a value by adding shell quotes.

The status line reads that file as data — it parses the keys it knows and ignores everything else, rather than executing it. So an unknown key is inert, not an error, and a value never needs shell quoting.

The keys

Ask the script, never this file and never memory.

bash "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/msu-statusline.sh" --config
