start-oz-cloud-session

name: start-oz-cloud-session description: Starts a new Oz (Warp) cloud agent run via the Oz API and returns the session link. Use when the user wants an Oz cloud session, Warp cloud agent, remote-oz worker, or mentions WARP_API_KEY and OZ_ENVIRONMENT_ID.

Start an Oz Cloud session

Create a new cloud agent run on the Oz Platform (Warp). Each run gets a run_id and a shareable session URL (session_link or https://oz.warp.dev/runs/...).

For Ralph multi-issue loops, use ralph with --worker remote-oz instead of this skill.

Prerequisites

Requirement	Notes
`WARP_API_KEY`	Oz / Warp API key
`OZ_ENVIRONMENT_ID`	Environment UID with repo + tooling configured — oz.warp.dev
Credits / plan	Cloud runs consume Warp credits; see billing

Optional: jq, curl for the helper script.

Quick start

export WARP_API_KEY=...
export OZ_ENVIRONMENT_ID=...

./.ralph/scripts/start-oz-cloud-session.sh \
  --title "Short run title" \
  "Your task prompt here"

Prints url=... and the session link. Capture the URL if you need to record it. Do not poll or wait for completion unless the user explicitly asked you to watch this run.

Workflow

Confirm environment — OZ_ENVIRONMENT_ID must match a configured environment (branch, secrets, MCP). Wrong env → agent lacks context.
Push branch if needed — Environments usually clone from GitHub; ensure the target branch exists on the remote before starting long AFK work.
Start run — Helper script or API POST /agent/run. The run executes asynchronously on Oz infrastructure.
Record URL (if needed) — Save session_link (or https://oz.warp.dev/runs/{run_id}). Stop — do not monitor the run.

Ralph / recursive chaining

When ralph-chain-next.sh starts the next Oz session:

Fire-and-forget — exit after create + URL; do not poll GET /agent/runs/{run_id} from the previous session.
Do not monitor the next session from the current agent.
sessions.log on the branch lists chained sessions for humans and cold-start workers.

Optional: paste the URL in chat only if a human in the same thread asked for it — not required for Ralph iteration handoff.

Helper script options

./.ralph/scripts/start-oz-cloud-session.sh --help

Flag	Effect
`--title`	Run title (default: truncated prompt)
`--environment-id`	Overrides `OZ_ENVIRONMENT_ID`
`--config-name`	Oz config name (default: `ad-hoc`)
`--model-id`	Optional model
`--auto-pr`	`create_pr: true`

API (manual)

curl -fsS \
  -H "Authorization: Bearer $WARP_API_KEY" \
  -H "Content-Type: application/json" \
  -X POST https://app.warp.dev/api/v1/agent/run \
  -d '{
    "prompt": "…",
    "title": "…",
    "config": {
      "environment_id": "'"$OZ_ENVIRONMENT_ID"'",
      "name": "ad-hoc"
    }
  }'
