checklist

checklist is a command for Claude Code from Sagart-cactus/claude-k8s-plugin. It costs 11 tokens per session (537 once invoked), scanned A, original, MIT.

A review checklist for Kubernetes operators, software that manages applications inside Kubernetes. It checks development safety, custom resource definitions, webhooks, and access permissions.

In plain words
What is it for?
It helps evaluate a Kubernetes operator and report whether its development cluster settings, schemas, webhooks, and role permissions pass, fail, or do not apply.
Why use it?
It provides a consistent way to spot configuration, validation, certificate, endpoint, and permission problems before they cause trouble.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

checklist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kubernetes Operator Quality Checklist

Evaluate the current project against each item below. For each item, report PASS, FAIL, or N/A with a brief explanation.

Safety (dev-only)

  • Target cluster is kind or explicitly allowed dev cluster
  • Leader election disabled for dev overlay
  • Single replica manager in dev
  • Webhook timeouts are short for dev (e.g., 10s)
  • Webhook only mutates resources it owns or is explicitly allowed to modify

CRD

  • Structural schema is valid (kubectl get crd <name> -o yaml shows no errors)
  • Required fields are marked in the schema
  • Default values are defined where possible
  • Status subresource is enabled (if status is used)
  • Printer columns are defined for useful kubectl get output

Webhooks

  • Validating webhook covers all invariants from requirements
  • Mutating webhook only defaults safe fields
  • Failure policy is appropriate (Fail for prod safety, Ignore for dev flexibility)
  • Certificates exist and are mounted correctly
  • Webhook service endpoints resolve

RBAC

  • Minimal verbs (only what the controller needs)
  • Minimal resources (no wildcards unless justified)
  • No unnecessary cluster-wide permissions
  • Separate roles for manager and webhook if needed

Fast Loop

  • make dev / tilt up starts without errors
  • Local compile succeeds
  • Binary sync into running pod works
  • Process restart is reliable after sync
  • Logs show new version after code edit
  • CRD changes are applied through Kustomize

Tests

  • Unit tests exist for core reconcile logic
  • Envtest or integration tests exist for webhook validation
  • Example CR manifests exist for manual testing

Troubleshooting (verify if any failures above)

  • Check Tilt logs for sync errors
  • Check pod logs for crash loops (kubectl logs -n <ns> <pod>)
  • Verify webhook service endpoints (kubectl get endpoints -n <ns>)
  • Check certificate secrets exist
  • Verify RBAC with kubectl auth can-i --as system:serviceaccount:<ns>:<sa>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
