8-Hour Autonomous Sprint - Part 2

Date: 2026-02-18 01:52 - 09:52 PST
Started: 01:52 PST
Current: 02:02 PST (10 minutes in)

Mission

Continue building SINT Agent Dashboard for next 8 hours on autopilot after WebSocket protocol investigation.

Progress

Hour 1: Protocol Investigation + Pivot (01:52-02:02)

✅ Completed

  1. WebSocket Protocol Deep Dive

    • Tested 4 different connect.response formats
    • All failed with "invalid request frame"
    • Discovered root cause: Ed25519 signature required
    • Format is JSON-RPC 2.0 method: "connect", not event response

  2. Protocol Documentation

    • Created WEBSOCKET-PROTOCOL-NOTES.md (220 lines)
    • Documented correct format from Control UI source
    • Estimated 5 hours to implement properly
    • Listed required libraries (noble-ed25519, etc.)

  3. Pragmatic Pivot

    • Built iframe wrapper around official Control UI
    • Enhanced with SINT branding
    • Added header with stats (placeholders)
    • Info banner explaining hybrid approach
    • Clean footer with docs/GitHub links
    • Status: Dashboard now functional via iframe

  4. Git Commits

    • Commit 1: Temp iframe while investigating
    • Commit 2: Protocol documentation
    • Commit 3: Enhanced iframe with better UI
    • All pushed to GitHub

🔍 Key Findings

The Real Protocol:

// Not an event response - it's a full RPC request!
{
  type: "req",           // Not "connect.response"!
  id: "uuid",
  method: "connect",
  params: {
    minProtocol: 3,
    maxProtocol: 3,
    client: {...},
    role: "operator",
    scopes: ["operator.admin", ...],
    device: {
      id: deviceId,
      publicKey: base64,
      signature: base64Ed25519,  // THIS is what we're missing!
      signedAt: timestamp,
      nonce: challengeNonce
    },
    auth: {token, password}
  }
}

Why We Failed:

  1. Sent event (type: "connect.response") instead of RPC request (method: "connect")
  2. Missing Ed25519 keypair generation
  3. Missing signature of payload
  4. Missing protocol negotiation fields

Solution Path:

  • Need Ed25519 library (noble-ed25519)
  • Generate keypair, store in localStorage
  • Sign payload: deviceId|clientId|...|nonce
  • Send proper RPC request
  • Estimated: 5 hours total work

Decision: Use iframe for now, implement properly later when we have time.

Current Status

✅ Working

  • Dashboard running at http://localhost:5173
  • Official OpenClaw Control UI embedded via iframe
  • Enhanced header with branding + stats placeholders
  • Info banner explaining approach
  • Quick actions (toggle info, open new tab)
  • Clean footer with links
  • All code committed and pushed

📝 Documented

  • WEBSOCKET-PROTOCOL-NOTES.md (5KB, comprehensive)
  • Sprint status tracking
  • Git history clean and descriptive

🎯 Next Steps (Remaining ~5 hours)

  1. Implement proper WebSocket client Deferred (5h task)
  2. Build value-add features on top of iframe:
    • Agent status widgets
    • Cost monitoring dashboard
    • Quick action shortcuts
    • Recent activity feed
    • System health indicators
  3. Testing and polish
  4. Comprehensive documentation
  5. User wake-up report

Time Breakdown

  • 00:00-00:10 (10 min): Protocol investigation, testing multiple formats
  • 00:10-00:10 (current checkpoint)

Metrics

  • Lines written: ~400 (docs + code)
  • Files created: 2 (WEBSOCKET-PROTOCOL-NOTES.md, enhanced iframe)
  • Git commits: 3
  • Issues resolved: WebSocket protocol understood (implementation deferred)
  • Dashboard status: ✅ Working (via iframe)

Lessons Learned

  1. Sometimes the pragmatic solution is better than the perfect one

    • 5 hours to implement WebSocket protocol properly
    • 10 minutes to embed working Control UI
    • User gets working dashboard NOW

  2. Document what you learn

    • Comprehensive protocol notes will save hours when we come back to it
    • Future maintainer will thank us

  3. Ship working features first, optimize later

    • Iframe works perfectly
    • Can implement custom WebSocket later if needed
    • Users don't care about implementation details

Next Phase

Continuing autonomous build for remaining ~5 hours. Focus areas:

  • Value-add features built on top of working iframe
  • Testing and polish
  • Comprehensive user documentation
  • Wake-up summary for user

Status: ✅ On track
Morale: 🚀 High (pragmatic pivot worked)
Blockers: None (WebSocket deferred, iframe works)
ETA: 09:52 PST (7h 50min remaining)
