15Options:
16 --isolated, --isolation, -i <env> Run in isolated environment (screen, tmux, docker, ssh)
17 --attached, -a Run in attached mode (foreground)
18 --detached, -d Run in detached mode (background)
19 --session, -s <name> Session name for isolation
20 --session-id <uuid> Session UUID for tracking (auto-generated if not provided)
21 --session-name <uuid> Alias for --session-id
22 --image <image> Docker image (optional, defaults to OS-matched image)
23 --volume, -v <spec> Docker bind mount/volume host:container[:mode] (repeatable, docker only)
24 --mount <spec> Docker --mount spec (repeatable, docker only)
25 --env, -e <KEY=VALUE> Environment variable for docker container (repeatable, docker only)
26 --privileged Run docker container in privileged mode (docker only)
27 --network <name> Connect to a named network (repeatable, docker only)
28 --network-alias <alias> Add alias to the first network (repeatable, docker only)
29 --on-kill-resume <N> Resume a killed (exit 137 / OOM) detached docker session up to N times
30 --recovery-command <cmd> Command to run in the same container on such a resume
31 --on-kill-resume-delay <min[-max]> Wait a random number of seconds before each such resume (default 0)
32 --memory <size|N%|MIN%-MAX%> Docker RAM cap; percentages use daemon capacity
33 --memory-swap <spec> Combined memory+swap cap (defaults to memory, no extra swap)
34 --cpus <n|N%|MIN%-MAX%> Docker CPU cap; ranges draw once per creation
35 --on-kill-resume-memory <spec> New memory cap before a qualifying OOM recovery
36 --cpu-penalty Enable delayed Docker CPU penalty (default off)
37 --cpu-penalty-cpus <n> Penalty cap (default 2 CPUs)
38 --cpu-penalty-trigger <p%> Busy threshold (default 95% of usable CPUs)
39 --cpu-penalty-trigger-window <d> Fully covered busy window (default 15m)
40 --cpu-penalty-release <p%> Quiet threshold (default 65% of penalty cap)
41 --cpu-penalty-release-window <d> Minimum quiet/capped window (default 15m)
42 Durations accept ms, s, m, h; --status reports penalty state
43 --endpoint <endpoint> SSH endpoint (required for ssh isolation, e.g., user@host)
44 --isolated-user, -u [name] Create isolated user with same permissions
45 --keep-user Keep isolated user after command completes
46 --keep-alive, -k Keep isolation environment alive after command exits
47 --auto-remove-docker-container Always remove docker container after exit (compatibility alias)
48 --always-cleanup-container Always remove docker container after exit
49 --keep-container Keep docker container filesystem after exit
50 --keep-container-on-fail Remove successful docker containers, keep failed or OOM-killed ones
51 --shell <shell> Shell to use in isolation environments: auto, bash, zsh, sh (default: auto)
52 --use-command-stream Use command-stream library for execution (experimental)
53 --status <id> Show status of execution by UUID or session name (--output-format: links-notation|json|text)
54 --list List all tracked executions (--output-format: links-notation|json|text)
55 --running With --list, only report executions that are still running
56 --upload-log <id> Upload the stored log for an execution UUID or session name
57 --stop <id> Ask a detached isolated execution to stop gracefully
58 --terminate <id> Terminate a detached isolated execution immediately
59 --attach <id> Attach to a running detached isolated execution
60 --read-only With --attach, follow output without sending input
61 --resume <id> Restart a stopped detached execution in the same environment
62 (append -- <command> to run a different command there)
63 --resume-all Re-attach or reconcile every execution still marked running
64 --cleanup Clean up stale "executing" records (crashed/killed processes)
65 --cleanup-dry-run Show stale records that would be cleaned up (without cleaning)
66 --version, -v Show version information
