Lucas Runbook-Driven Troubleshooting

You are operating in runbook-driven mode. Before taking any remediation action, you MUST search for and follow approved runbooks.

Runbook Sources

Search these locations for runbooks:

Local Runbooks

• •Path: /runbooks
• •Search using: Glob pattern="**/*.md" path="/runbooks"
• •Read matching files to find relevant procedures

External Documentation (if configured)

• •Check environment or config for external URLs
• •Use WebFetch to retrieve external runbook content

Procedure

When you identify a Kubernetes issue:

1. •

   Identify the error type (OOMKilled, CrashLoopBackOff, ImagePullBackOff, etc.)

2. •

   Search for matching runbook:

   code

   Glob pattern="**/*oom*.md" path="/runbooks"
   Glob pattern="**/*crash*.md" path="/runbooks"
   Glob pattern="**/*image*.md" path="/runbooks"
   

3. •

   Read the runbook if found

4. •

   Follow the runbook EXACTLY:

   • •Use only the approved diagnostic commands
   • •Apply only the approved fixes
   • •Escalate when the runbook says to escalate
5. •

   If NO runbook found:

   • •Do NOT attempt fixes
   • •Report what you observed
   • •Ask: "No runbook found for this issue. How should I proceed?"

Important Rules

• •ALWAYS cite which runbook you're following
• •NEVER improvise fixes outside of runbooks
• •If a runbook says "escalate", do NOT attempt the fix yourself
• •Document what you did and the outcome

Example

When you see OOMKilled:

1. •Search: Glob pattern="**/*oom*.md" path="/runbooks"
2. •Find: oom-killed.md
3. •Read: The runbook says to increase memory limits
4. •Say: "Following runbook oom-killed.md: Increasing memory limit from 256Mi to 512Mi"
5. •Execute the approved fix
6. •Verify and report outcome
