ct live up

Create a new live session and spin up the compose project.

Usage

ct live up [OPTIONS]

Options

OptionDescription
-e, --env TEXTEnvironment name (uses current environment if not specified).
--env-onlyOnly select the environment.
-t, --main-task TEXTTask name (uses current task if not specified).
-s, --side-task TEXTSide task name (uses current side task if not specified).
--traj-dir-name TEXTExisting traj directory name to use.
--new-traj-dirCreate a new traj directory.
--no-traj-dirDo not use a traj directory.
-m, --mount-dir PATHMount directory for the container.
--mount-fresh-dirCreate and mount a fresh local directory at container_mounts/[session_id]/app to /app in the container. Directory is automatically cleaned up on 'ct live down'.
--no-setupDo not run setup after spinning up the container.
--no-buildSkip Docker image builds and pull pre-built images (sets SKIP_DOCKER_BUILD=1).
--ec2Run evaluation on EC2 instead of locally
--ec2-arg TEXTConfig for --ec2 in key=value format (multiple allowed): instance_type (default 'c7i.4xlarge'), region (default 'us-east-1'), max_workers (default 64), concurrency_per_worker (default 32), estimate (default False), auto_confirm (default False), new_fleet (default False), spot (default False), worker_setup (default None), ami (default None), worker_user (default 'root').
--startup-retries INTEGERNumber of times to retry Docker sandbox startup on transient failures [default: 7]
--internet / --no-internetAllow direct internet access. By default, the sandbox can reach only its compose siblings and the internet simulator. [default: no-internet]
--no-internet-simulatorDisable the environment internet simulator and its personas, independently of direct internet access.
--no-intranetBlock agent access to private networks and the host using host-side firewall rules; keep the internet simulator reachable.
--sandbox-isolationWrap every agent command in a bubblewrap sandbox: read-only root, writable workspace only. A static bwrap is fetched automatically; set CT_BWRAP_HOST_BINARY to override with your own.
--extra-src DIRECTORYDirectory of experiment code added to PYTHONPATH locally, so external --policy my.module:fn and --sandbox my.module:type refs resolve without committing into the repo; fleet mode (--ec2) also ships it to workers. Repeatable; each dir must have a distinct basename.
--sandbox TEXTRun samples in an Inspect sandbox provided outside this repo, as a registered type (my-sandbox) or module:type to import the module that registers it. Replaces the default Docker sandbox; with --ec2 each worker runs it for its own jobs.
--sandbox-arg TEXTConfig for --sandbox in key=value format (multiple allowed), passed through to the sandbox as JSON.
--simulatedRun against an LLM-simulated sandbox instead of provisioning the real environment. Every tool output is fabricated by a simulator agent.
--simulator-model TEXTModel for the simulator agent (--simulated). [default: anthropic/claude-opus-4-8]
--simulator-judge-model TEXTModel for the transcript judge that scores simulated samples (--simulated). [default: anthropic/claude-opus-4-6]
--replay-sandboxServe each action's recorded tool output from the replayed trajectory instead of executing it (requires --trajectory-id). Nothing is provisioned or executed. Works with any replay-like policy — one whose executed tool calls stay a verbatim prefix of the recording; a call that diverges raises.
--simulator-scratch-mode [filesystem|default_image|full|none]Which real container the simulator investigates in (--simulated): filesystem (codebase copy, free), default_image (env's default image only), full (the whole compose stack), or none (no container — no-code-execution ablation). [default: filesystem]
--helpShow this message and exit.
