Effective Prompts

Include Cluster Context

# Good
@kai analyze production EKS cluster
in us-west-2 for pod resource
optimization

# Avoid
@kai check our containers

Define Success Metrics

# Good
@kai improve cluster utilization
while maintaining <30s pod startup
and 99.9% availability

# Avoid
@kai make cluster better

Connection Requirements

Kai requires Kubernetes cluster access with monitoring capabilities:

Component	Required Access
Kubernetes API	Read access to pods, nodes, deployments, services
Metrics Server	Resource metrics for pods and nodes
Events	Cluster events for troubleshooting
Logs	Container logs for debugging

@kai analyze cluster resource utilization

# Step 2: Identify waste
@kai identify pods with >50% overprovisioned resources

# Step 3: Plan
@kai #recommend right-sizing with zero-downtime approach

# Step 4: Monitor
@kai #dashboard track resource utilization after changes

Incident Response

# Step 1: Identify
@kai identify unhealthy pods and failing deployments

# Step 2: Investigate
@kai analyze logs and events for root cause

# Step 3: Remediate
@kai #recommend immediate actions to restore service

# Step 4: Prevent
@kai #recommend changes to prevent recurrence

Capacity Planning
