jr-sysinfo

Keeps the Mac awake while Claude works, shared by every session on the machine, and warns before the next sleep.

A coloured project badge and its branch, on the right above the prompt, so you always know which window you are typing in. Hidden until you type /jr-badge. A `badge: LABEL #hex` line in CLAUDE.md sets your own.

A toast 30 seconds before the prompt cache goes cold, and on /jr-cache-clock a quiet countdown above the prompt: how long the cache stays warm after Claude's last reply, going green to red, and the last cache hit rate.

Nudges you toward small atomic commits: when uncommitted changes pass a threshold, a band and a toast suggest a split by folder.

The context window in one quiet row above the prompt: a mini bar coloured by category, the fill and the window, turning into an alert when compaction is near. /jr-context hides or shows it, /jr-context details opens the full bar with its legend.

A decision journal per project: /jr-decisions <decision> or a prompt starting with "decision:" records one, /jr-decisions lists them, /jr-decisions export writes docs/decisions.md.
