Accepts `prewarm: bool` (v0.2.0+) |\n| `branch_sandbox` | **Branch a running sandbox into a new tag (v0.2.0+).** Accepts `diff: bool` for v0.3's 6-15× source-pause reduction on typical agent workloads (143× ceiling). |\n| `list_sandboxes` | List live sandboxes |\n| `get_sandbox` | Inspect one sandbox by id |\n| `exec_command` | Run a shell command in a sandbox |\n| `eval_code` | Evaluate Python against the warmed PID-1 |\n| `wait_for_text` | Poll a file in the guest for a marker string (v0.2.0+) |\n| `ping_sandbox` | Health-check a sandbox |\n| `kill_sandbox` | Terminate one sandbox |\n\nThe killer one is **`branch_sandbox`**: pause a running agent\nsandbox, snapshot, fan out N children that inherit the source's\nexact state and diverge under copy-on-write. Modal does this as\ntheir proprietary moat; forkd is the open-source equivalent. See\n[`bench/pause-window/RESULTS-v0.3.md`](../../bench/pause-window/RESULTS-v0.3.md)\nfor the measured numbers.\n\nEach tool maps 1:1 onto a forkd-controller REST endpoint\n([`docs/API.md`](../../docs/API.md)).
