ODSH Bridge — OpenClaw × DeepSeek Harness connectivity bridge

One-line positioning: lets DeepSeek Harness (DSH, the execution layer) reach the OpenClaw (brain/persona layer) gateway over WebSocket, hand off tasks reliably between the two containers through a shared directory bridge (envelope + daemon), and — since v1.1 — operate a real Windows desktop on the host machine via SSH + Cua Driver (no OpenClaw Desktop, no dedicated node daemon).

Everything here comes from a real integration that was run and verified in 2026-08 on the docker agent-mesh network; anything not verified or speculative is marked ⚠️ verify yourself. All credentials are placeholders — no real token/secret should ever appear in this repository.

There are three data flows:

1. Realtime channel: A DSH script connects to the OpenClaw gateway on 18789 as a "paired device" (HTTP Upgrade + origin allowlist + Ed25519 signature pairing + connect.challenge → hello-ok), then calls methods in a JSON-RPC style.
2. Async bridge: Either side writes a task envelope to Input/T-*.json → the daemon watches and executes it → atomically writes back Output/<taskId>_result.json, optionally notifying a Discord channel via oc-send.
3. Windows desktop execution (v1.1+): DSH calls oc-cua.mjs → ssh into the Windows host → invokes cua-driver call <tool> '<json>' → the driver operates the real desktop (snapshot, click/type/hotkey, browser via CDP, app launch) without stealing focus.

2. Verified features

Each item below was actually exercised and passed in the real environment.

• ✅ Gateway WebSocket handshake + Ed25519 device pairing: HTTP Upgrade (with explicit Origin) → connect.challenge (nonce) → sign the v2 claim string → connect → hello-ok; the device is approved through the Control UI (operator role + 5 scopes). deviceId = hex(SHA-256(Ed25519 public key)) stays constant, so a device approved once stays approved forever. Known pitfall fixed: the claim and device.signedAt must come from the same Date.now() call (see docs/PROTOCOL.md §2.3).
• ✅ Gateway method calls: agents.list, status, health, talk.catalog, talk.session.create, tools.invoke (message send/read), config.schema.lookup — all pass.
• ✅ Async bridge: envelope → daemon → result, with .tmp → rename atomic writes and an idempotent .state store; kinds echo / notify / run-command / write-file / read-file / bridge-status.
• ✅ Windows desktop execution via Cua Driver (v1.1): verified from the DSH container over SSH:
  • cua-driver --version → 0.21.0
  • get_screen_size → real host resolution (e.g. 2560×1440)
  • get_accessibility_tree → live desktop process tree via UIA
  • full tool surface: get_desktop_state, browser_navigate/click/type/pointer, launch_app, kill_app, click/double_click/right_click/hotkey/type/scroll, list_apps, list_windows …

3. Deploy in minutes

Requires: Docker + two images — OpenClaw (official openclaw/openclaw:latest) and DSH (no public image; build deepseek-harness:local from the DeepSeek Harness repo).

# 1. Clone, then scaffold the bridge with the interactive wizard
git clone https://github.com/Mikoribbit/odsh-bridge.git && cd odsh-bridge
chmod +x scripts/new-bridge.sh
./scripts/new-bridge.sh            # visual prompts; press Enter to keep defaults

# 2. Bring up OpenClaw + DSH (bridge daemon auto-starts inside DSH)
docker compose up -d              # uses the generated docker-compose.yaml

# 3. Pair once, then it just works
node src/oc-client.mjs connect    # approve the deviceId in the OpenClaw Control UI

# (optional) verify daemon health + a round-trip
node src/dshtrigger.mjs status
node src/dshtrigger.mjs send --kind echo --text "hello"

5. Credits

• odsh-interop (ClawHub) — the OpenClaw-side skill is published on ClawHub (package: odsh-interop); install with openclaw skills install odsh-interop.
• Cua — this project's Windows desktop execution layer is powered by Cua Driver (by the trycua team). Huge thanks for an open, cross-platform, focus-safe computer-use driver that lets agents drive desktop apps without stealing the user's cursor. The Cua Driver is independently licensed by their authors — see their repository for details.
