Checking Deploy

Deployment Validation

Validate Kubernetes, Terraform, Helm, GitHub Actions, and Docker configs.

Use TodoWrite to track these 5 phases:

1. Detect infrastructure files
2. Spawn validation agent
3. Collect results
4. Research best practices (if needed)
5. Present summary

Parse $ARGUMENTS:

• --background → Run in background, return immediately with agent ID

Step 1: Detect Infrastructure Files

Use Glob to find infrastructure files (quick scan):

• **/*.yaml, **/*.yml - K8s, Helm, Kustomize
• .github/workflows/*.yml - GitHub Actions
• **/*.tf - Terraform
• **/Dockerfile*, **/docker-compose*.yml - Docker

Step 2: Spawn Validation Agent

Based on detected file types, spawn infra-engineer agent:

Task(
  subagent_type="infra-engineer",
  run_in_background={true if --background else false},
  description="Infrastructure validation",
  prompt="Validate {detected_types} infrastructure in this repository.

  Run these validations (only for detected file types):

  **Kubernetes:**
  - kubectl apply --dry-run=client -f <files>
  - Check: security contexts, resource limits, non-root users
  - Check: liveness/readiness probes defined
  - Check: no 'latest' image tags

  **Helm:**
  - helm lint <chart>
  - helm template validation
  - Check: values.yaml has sensible defaults

  **GitHub Actions:**
  - actionlint (if available)
  - Check: secrets not hardcoded
  - Check: permissions minimized (not 'write-all')
  - Check: pinned action versions (@vX.Y.Z not @main)

  **Terraform:**
  - terraform fmt -check
  - terraform validate
  - Check: no hardcoded credentials
  - Check: state backend configured

  **Dockerfile:**
  - Multi-stage builds where appropriate
  - Non-root user (USER directive)
  - Pinned base image tags (not :latest)
  - No secrets in build args

  Output format:
  PASS/FAIL per category with file:line for issues.
  Severity: CRITICAL / IMPORTANT / SUGGESTION"
)

If --background: Return agent ID immediately for later collection.

Step 3: Collect Results (if not background)

TaskOutput(task_id=<agent_id>, block=true)

Step 4: Research if Needed

For uncertain findings, use Perplexity for current best practices:

mcp__perplexity-ask__perplexity_ask with:
"Current best practices for {specific concern} in {technology} 2024-2025"

Step 5: Present Summary
