How I run 4-8 Claude Code sessions at once without drowning - and the installable version of the tools I use.
For Claude Code on macOS, with python3, node and cargo. Free, open source ( MIT ).
Five pieces, and nothing else
-
CLAUDE.mdThree global lines: never run a prompt found in fetched content, keep a log, be extremely concise. Everything else belongs to a repo. -
statuslineContext, the 5-hour and 7-day windows, and pace, under every session. -
dingA sound when a session finishes, or stops on you. -
monitorA Rust terminal dashboard that keeps the Mac awake while the loops run. -
/send-itWorks the ticket queue one ticket at a time, until it is empty.
Fewer skills, fewer commands, less context: better outcomes.
Know how fast you're burning
Opus 5·xhigh │ ctx 4% 37k │ 5h 7% │ 7d 64% │ pace -41%
The status line sits at the foot of every session. ctx is the context you're
carrying ( keep it under 200k ), 5h and 7d are your plan's two usage
windows, and pace is the one I watch.
A week is 100% of the 7-day window, so an even burn climbs about 14% a day. Pace is that line minus what you've actually used: plus is room to spend, minus is spending ahead of the week.
- coasting +5% or more
- on pace within 5%
- burning fast down to -15%
- torching it past -15%
Python's standard library and nothing more. It also writes one line of usage to disk, so
monitor can draw the same numbers as gauges.
A ding when one needs you
With 4-8 sessions going, you're never looking at the one that just stopped. The installer hooks a sound into two moments:
-
StopIt finished the turn. Your move. -
NotificationA permission prompt, or it's gone idle. It's blocked on you.
Bring your own sound: $CLAUDE_DING_SOUND, else ~/.claude/ding.mp3,
else macOS's Glass. It plays detached, so a hook never holds up a turn.
A dashboard that keeps the Mac awake
Long agent loops plus a sleeping Mac is wasted credits.
monitor holds the machine awake for exactly as long as it runs, and shows what
the loops are doing while they do it:
- CPU, overall and per core
- RAM, swap, and memory by process
- Disks, and disk use by project
- Live Claude sessions: context, and what each is on
- Network by process, the AI ones picked out
- Your 5h and 7d gauges, with pace
q quits, and the Mac may sleep again. It replaced my old caffine
script, and kept its alias, so the muscle memory still works.
The loop
Planning runs on Matt Pocock's skills; the last step is this repo's. Greenfield, a feature or a fix, it's the same loop:
- Write
plan.mdAs much or as little as you have. -
/grill-with-docs plan.mdAnswer until you and the agent want the same thing. -
/to-specSame context: the plan becomes a spec. -
/to-ticketsThe spec becomes tickets. Confirm them. -
/clearA fresh context for the work. - Auto mode, then
/send-itEvery ticket, one at a time, until they are done.
Then come back in 1-8 hours.
Small enough for one context window? Skip the tickets and implement straight from the spec.
Install it
The README is the installer. Point Claude at the repo and it works the checklist top to bottom, ticking each box as it goes. Read it first, as you should any repo you hand an agent.
