* the agent-server from local source and installs openhands-sdk,
* openhands-tools and openhands-workspace as editable so source edits are
* picked up without manual reinstall.
* - OH_AGENT_SERVER_GIT_REF: Git ref for agent-server
* Secrets:
* The session API key is automatically seeded into agent-server secrets
* as OPENHANDS_AUTOMATION_API_KEY, making it available to agents in conversations.
* Both the agent-server and automation backend use the same key value
* and the same `X-Session-API-Key` header for authentication.
* AUTOMATION_KV_SECRET is derived from the session key if not set explicitly,
* enabling the KV store out of the box for local development.

Agent Canvas + Automation Development Stack
Runs agent-canvas with the automation backend (via uvx, no clone needed).
Uses a standalone ingress proxy to route traffic.
USAGE:
node scripts/dev-with-automation.mjs [options]
OPTIONS:
-p, --port <port> Ingress port (default: 8000)
--automation-ref <ref> Git ref for automation (branch/tag/SHA)
--automation-repo <url> Git repo URL (default: ${DEFAULT_AUTOMATION_REPO})
--static Serve an existing production build instead of Vite
--static-dir <dir> Static build directory (default: build/)
--skip-build Reuse build/ when the launcher builds static assets
--dynamic Force Vite dev server when a wrapper defaults static
--frontend-only Start only the frontend behind ingress
--backend-only Start only agent-server + automation behind ingress
-v, --verbose Show detailed output
-h, --help Show this help
ENVIRONMENT VARIABLES:
PORT Alternative to --port
OH_AUTOMATION_GIT_REF Git ref for automation (overrides default version)
OH_AUTOMATION_VERSION Specific PyPI version for automation (default: ${DEFAULT_AUTOMATION_VERSION})
OH_AUTOMATION_LOCAL_PATH Absolute path to a local automation checkout (overridden only by --automation-git-ref)
OH_AGENT_SERVER_LOCAL_PATH Absolute path to a local software-agent-sdk checkout (highest precedence)
OH_AGENT_SERVER_GIT_REF Git ref for agent-server SDK (overrides default version)
OH_AGENT_SERVER_VERSION Specific PyPI version for agent-server
OH_SECRET_KEY Secret key for sessions
SECRETS:
The session API key is automatically seeded into agent-server secrets
as OPENHANDS_AUTOMATION_API_KEY, making it available to agents in conversations.
Both backends (agent-server and automation) share the same key value.
AUTOMATION_KV_SECRET defaults to the session key so the KV store works
out of the box; override with an explicit value for stronger isolation.

Main UI: http://localhost:PORT/
API Docs: http://localhost:PORT/api/automation/docs
