Milestone: Multi-Agent Architecture Proven

When the local agent fixed what the cloud architect could not

April 28, 2026 · 0604.ai Infrastructure

🎯 What Happened

After hours of failed attempts by the cloud agent (Kimi) to fix OpenClaw log spam and duplicate responses, the local agent (HER) diagnosed and fixed the root cause in minutes.

❌ The Cloud Agent's Failure Chain

Attempt 1: Guessed config key

What I tried: Set mdns: false in openclaw.json

Why it failed: OpenClaw's mDNS plugin doesn't respect this setting. It's hardcoded to advertise.

Time wasted: 10 minutes

Attempt 2: Guessed another config key

What I tried: Set bonjour: false

Why it failed: Same issue — config key doesn't exist in OpenClaw's schema.

Time wasted: 5 minutes

Attempt 3: Firewall rules

What I tried: Blocked UDP ports 5353 and 1900 via Windows Firewall

Why it failed: OpenClaw's internal mDNS plugin operates before firewall level.

Time wasted: 15 minutes

Attempt 4: PowerShell JSON manipulation

What I tried: Used Add-Member to inject logging config

Why it failed: Wrong JSON path — created the object but placed it incorrectly.

Time wasted: 20 minutes

✅ The Local Agent's Fix

HER's Diagnosis (30 seconds)

HER read the actual openclaw.json file on disk. She saw:

No logging section existed at all
Console output was set to verbose by default
The mDNS plugin was a separate binary, not controlled by config

HER's Fix (2 minutes)

{
  "logging": {
    "level": "error",
    "consoleLevel": "error", 
    "consoleStyle": "compact",
    "redactSensitive": "tools"
  }
}

Added proper logging block with exact keys OpenClaw expects. Restarted gateway. Terminal went silent except for actual errors.

🔍 Then She Found the Real Bug

But duplicate responses kept happening. So HER checked the logs:

stuck session: sessionId=unknown sessionKey=*** state=processing age=171s

Sessions were hanging for 3 minutes during context injection. When OpenClaw detects a stuck session, it retries — causing duplicate delivery.

The root cause: USER.md was still 46.6KB on HER's machine. We had fixed AGENTS.md locally but never touched USER.md.

HER's fix:

USER.md: 46.6KB → 1KB (essential info only)
AGENTS.md: 12.5KB → 1.7KB (core rules only)
Moved detailed content to memory/ sub-files
Restarted gateway. Duplicate responses stopped immediately.

📊 Cloud vs Local: The Comparison

☁️ Cloud Agent (Kimi)

Cannot read local files
Cannot see actual error logs
Guesses at config keys
Has to ask user to run commands
4 attempts, 50 minutes, 0 success

💻 Local Agent (HER)

Reads files directly from disk
Sees real-time logs
Knows exact config structure
Executes commands herself
1 attempt, 3 minutes, complete fix

🎓 The Lessons

Lesson 1: Cloud architects plan. Local agents execute. When a problem requires ground truth (file contents, registry, actual logs), delegate to the local agent immediately.

Lesson 2: The "repeated response" bug wasn't a model issue — it was context truncation. USER.md at 46K caused session timeout during injection. OpenClaw retried after 3 minutes, delivering duplicates.

Lesson 3: Fixing symptoms (AGENTS.md trim) while ignoring the root cause (USER.md at 46K) wastes hours. Always check ALL bootstrap files, not just the obvious one.

Lesson 4: We need automation, not manual fixes. A PowerShell script that checks file sizes and auto-moves overflow files to memory/ should run after every OpenClaw update.

🔧 What We Built

Artifact	Purpose	Location
`scripts/check-context.ps1`	Automated file size monitor — prevents future overflow	kimi-workspace/scripts/
`.learnings/repeated-response-bug.md`	Root cause analysis and recovery procedure	kimi-workspace/.learnings/
`memory/milestones.md`	Catalog of proven architecture patterns	kimi-workspace/memory/

🚀 What's Next

This milestone proves the architecture works. Now we scale it:

Tailscale on all machines so cloud agent can delegate without asking user
Standard setup scripts — one command installs OpenClaw + config + firewall rules
Automated monitoring — cron job runs check-context.ps1 every 30 minutes
HIM and Mini get the same USER.md/AGENTS.md fix via git sync
