For AI agents: The documentation index is at https://docs.digitalocean.com/llms.txt. Markdown versions of pages use the same URL with index.html.md in place of the HTML page (for example, append index.html.md to the directory path instead of opening the HTML document).

Usage

doctl harness-runtime [flags]

Aliases

agent, agents, ohr

Description

Managed Agents Runtime Services (M.A.R.S) — run a coding agent (Claude Code, OpenCode, Codex, …) in a DigitalOcean sandbox.

Currently in public preview. Public Preview Terms.

Two verbs cover the lifecycle, split on whether you want to watch:

• launch puts you in a session — creating it first if you gave it something to create from, or attaching to one you already have.
• create makes a session and leaves it alone, for scripts and agents.

Create a session and land in the chat:

doctl harness-runtime launch \
  --harness claude-code \
  --gh-repo owner/repo \
  --prompt "Review the README"

Or create without attaching, then open it later:

doctl harness-runtime create \
  --harness claude-code \
  --gh-repo owner/repo \
  --prompt "Review the README"
doctl harness-runtime launch my-session

Session commands accept a session ID or an exact unique name.

Renamed in recent betas. open-harness-runtime is now harness-runtime (also agent, agents, ohr). start / run are now create (both still work). attach is now launch (also up / chat / attach; interactive only — scripts should use create). destroy is now remove (still accepted as destroy / rm).
