Unnamed Skill

---

name: Constitution Enforcer description: Validate Kubernetes manifests, Helm charts, and Dapr configs against security and governance rules. Use when: (1) Generating K8s manifests, (2) Creating Helm charts, (3) Building Docker configurations, (4) Reviewing Dapr components, (5) After any infrastructure code generation, (6) Before deployment reviews. Validates container security, RBAC policies, resource limits, Dapr standards, and network policies.

Overview

This skill enforces cloud-native governance rules for Kubernetes deployments. Invoke it before and after generating infrastructure code to ensure compliance with security policies.

Validation Scripts

Use the provided validation scripts for automated checking:

# Validate Kubernetes manifests
python scripts/validate_k8s.py <manifest-file>

# Validate Helm charts
python scripts/validate_helm.py <chart-directory>

# Validate Dapr components
python scripts/validate_dapr.py <component-file>

# Run all validations
bash scripts/validate_all.sh <directory>

Container Security Rules

Every container MUST have these security settings:

securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  runAsGroup: 1000
  allowPrivilegeEscalation: false
  readOnlyRootFilesystem: true
  capabilities:
    drop:
      - ALL

Violations that BLOCK deployment:

• Running as root (UID 0)
• Privilege escalation enabled
• Using latest image tag
• Host network or host PID enabled
• Missing security context

RBAC Policies

Rule	Requirement
Dedicated ServiceAccount	Each app has its own SA
No default SA	Never use default service account
Namespace-scoped	Use Role, not ClusterRole
Least privilege	Only permissions actually needed
No cluster-admin	Never bind cluster-admin to apps

Forbidden:

• Wildcard permissions (*)
• ClusterRoleBinding to applications
• bind, escalate, impersonate verbs

Resource Limits

Every container MUST specify:

resources:
  requests:
    cpu: "<value>"
    memory: "<value>"
  limits:
    cpu: "<value>"
    memory: "<value>"

Defaults by component:

Component	CPU Req	CPU Limit	Mem Req	Mem Limit
Frontend	100m	500m	128Mi	256Mi
Backend	200m	1000m	256Mi	512Mi
MCP Server	100m	500m	128Mi	256Mi
Dapr Sidecar	100m	300m	128Mi	256Mi

Dapr Configuration Standards

Every Dapr component MUST have:

• Explicit namespace (never "default")
• Credentials via secretKeyRef (never inline)
• Scopes defined (never empty)
• mTLS enabled in Configuration resource

Kafka Event Governance

• Topic naming: <domain>.<entity>.<event> (e.g., todo.task.created)
• Auth required in production
• Replication factor 2+ in production

Database Connection Security

• SSL required: sslmode=require
• Credentials in Kubernetes Secret only
• No hardcoded credentials anywhere

Network Policies

• Default deny all ingress/egress
• Explicit allow rules only for required traffic

Validation Output Format

When violations found, output:
