Command reference

Commands

Command	Purpose
`oar --version`	Display the installed OAR version.
`oar init PROFILE_ROOT --model MODEL_ID`	Create editable copies of the packaged profiles.
`oar validate PROFILE_DIRECTORY`	Check the profile and its local resources.
`oar doctor`	Display the OpenShell version, gateway status, and inference configuration.
`oar run PROFILE_DIRECTORY --task TASK --output PATH`	Run a task and save its result.

init creates both profiles by default. Repeat --profile NAME to select which ones to create. It refuses to overwrite existing profile directories. --thinking accepts off, minimal, low, medium, high (default), xhigh, or max; choose a level your model supports.

Use oar COMMAND --help for all options. For a task's inputs, variables, and output format, put the profile and task before --help:

oar run ./profiles/code-reviewer --task review-repository --help

Run options

Option	Meaning / default
`--task NAME`	Required. Select a task in the profile.
`--output PATH`	Required. Save the result to this path on your machine.
`--input PATH`	Required when the task declares a document or repository input.
`--prompt-var NAME=VALUE`	Set a declared prompt variable. Repeat for several.
`--upload SOURCE:DESTINATION`	Upload a supporting file or directory. Repeat for several.
`--env KEY=VALUE`	Add a non-secret sandbox environment value. Repeat for several.
`--gateway NAME`	Use this gateway; otherwise use OpenShell's selected gateway.
`--workspace NAME`	Use this OpenShell workspace. Default: `default`.
`--timeout-seconds N`	Timeout for sandbox creation and agent execution, applied separately. Default: `1200`.
`--dry-run`	Validate the request and print planned operations without executing them.
`--keep-sandbox`	Retain the sandbox and print its name for debugging.

Choose a gateway and workspace

A gateway runs your sandboxes and connects them to inference. A workspace is a named group of resources on that gateway. It is different from the /workspace directory inside a sandbox.

Use the same --gateway and --workspace options with doctor and run. OAR uses existing gateways, workspaces, and inference configuration; manage them through OpenShell.

doctor displays configuration; it does not send a model request. Exit 0 means the inspection commands succeeded, not that inference is ready. If inference shows Not configured, configure a provider and route in OpenShell before running a task.

Upload supporting files

Use --input for the task's main file or directory. Use --upload for additional material, with a local source on the left and a sandbox destination on the right:

Option	Path the agent sees
`--input ./notes.txt` on a document task	`/workspace/input/document.txt`
`--input ./my-project` on a repository task	`/workspace/input/my-project/`
`--upload ./requirements.md:/workspace/requirements.md`	`/workspace/requirements.md`
`--upload ./references:/workspace`	`/workspace/references/`

Document inputs preserve ordinary file extensions. Directory uploads place the source directory inside the destination, like cp. Point the prompt or context variable at supporting files so the agent knows why they are there.

For uploads shared by every run, use sandbox.upload in profile.yaml. Uploads happen in order: profile uploads, required input, additional CLI uploads, then OAR's runtime files. Earlier files can be overwritten by later uploads. Relative upload sources are resolved from the caller's working directory. Use /workspace for your files; /sandbox/oar-runtime and /sandbox/artifacts are reserved for OAR.

Upload only what the agent needs. The destination may be a remote machine. Keep secrets in OpenShell's provider configuration; prompt variables and --env are for non-secret values. Environment names use letters, numbers, and underscores, cannot start with a number, and cannot start with OPENSHELL_.

What happens during a run

Each oar run moves work from your machine into a new sandbox and brings back one result. OAR checks the request before attempting to create the sandbox.

1. PREPARE · your machine / CI
   Load profile + task + input
   Fill in prompt variables
              |
              v
2. RUN · new OpenShell sandbox
   Create using the profile's policy
   Upload input, prompt, skills + schema*
   Run the agent using gateway inference
              |
              v
3. COLLECT · your machine / CI
   Download and validate the result
   Pass --> save to --output
   Fail --> keep existing output
              |
              v
4. CLEAN UP · on success or failure
   Verify ownership, then delete sandbox
   --keep-sandbox skips deletion
   Gateway stays running

* If the selected task declares a schema.

OAR downloads only the result, which must be non-empty and no larger than 1 MiB. For a JSON task, it must also match the schema named by the profile task. OAR replaces the host output only after validation succeeds; a failed download or invalid result leaves an existing output untouched.

Once sandbox creation is attempted, any failure skips the remaining steps and goes to cleanup. OAR checks the sandbox name and its oar-run-id ownership label before deleting it; if that check fails, it leaves the sandbox alone. --keep-sandbox skips deletion. Cleanup can fail after the result has already been saved; it does not undo that output.

Use OAR in CI

A CI job uses the same oar run command as a terminal. Install OAR and OpenShell, make the gateway and inference route available, then run the profile and retain the output file. Version the profile alongside the project and pin the OAR release in the job.

One gateway can serve several sequential runs; each run gets its own sandbox. Use the CI job's timeout to cap total wall time: --timeout-seconds applies to creation and execution separately, and uploads and cleanup take additional time.

Exit code	Meaning
`0`	The result was validated and saved, and requested cleanup succeeded.
`1`	OpenShell execution, timeout, download, ownership checking, or cleanup failed.
`2`	A command argument, profile, input, or prompt variable was invalid.
`3`	The downloaded result was empty or failed validation.

These are run outcomes. A reviewer can return needs_changes while OAR exits with 0. Read the JSON verdict if your CI policy depends on the review.

Troubleshooting

Symptom	Next step
`oar: command not found` after installation	Run `uv tool update-shell`, then open a new terminal.
`doctor` cannot connect	Check OpenShell gateway status and that you selected the intended gateway.
No inference route or model request fails	Check the route in OpenShell, then the model ID and thinking level in your profile.
`init` says a profile already exists	Use the existing profile or choose a new destination.
Unknown task or prompt variable	Run task-specific `--help` and check `profile.yaml`.
Missing or invalid result	Read the run's errors; use `--keep-sandbox` on the next run to inspect it.
No output with `--dry-run`	Expected: the plan is printed, but no result file is created.

To run the current source without installing a tool, use uv run --frozen oar from projects/openshell-agent-runner. See installation for making this version available as oar from any directory.
