image

image is a skill for Claude Code from controlplane-com/ai-plugin. It costs 53 tokens per session (4,150 once invoked), scanned A, original, MIT.

A guide to building, storing, and using container images on Control Plane. A container image is a packaged application and its dependencies; a registry stores those images for deployment.

In plain words
What is it for?
Use it to build images locally or remotely, push them to the private registry, manage tags and digests, and configure pull secrets for private images.
Why use it?
It removes the need to manage every image step locally and helps diagnose incorrect image references, incompatible images, and missing permissions.

  • high Privilege Escalation · line 63
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

image 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 17d 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.

How it starts

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Control Plane Images

Every org gets a private registry at ORG.registry.cpln.io — a standard Docker registry (docker login/push/pull/search all work). Pushing a tag automatically creates an image resource named NAME:TAG in the org (read-only repository, tag, digest, manifest fields; only metadata tags are editable). An image resource is never created directly — POST /org/ORG/image returns 403 "You can create an image only by pushing" — but a build can run on Control Plane instead of local Docker (cpln image build --remote), which is the answer whenever there is no Docker daemon. The recurring failures are a wrong reference form, a non-linux/amd64 image (exec format error), and a missing or mismatched pull secret.

Image references

Source Reference in workload spec Pull secret
Your org's registry (preferred) //image/NAME:TAG (long form /org/ORG/image/NAME:TAG) No — automatic
Your org's registry (hostname form) ORG.registry.cpln.io/NAME:TAG — the API rewrites it to the link form on write No — automatic
Another Control Plane org OTHER-ORG.registry.cpln.io/NAME:TAG — stays a literal external reference Yes (docker)
Public registry Exact string: nginx:latest, ghcr.io/owner/app:v1 — never add a docker.io/ prefix No
Private external registry (ECR, GCR/GAR, private Docker Hub, ACR...) Full host path, e.g. ACCOUNT.dkr.ecr.REGION.amazonaws.com/app:v1 Yes
  • "Image name" always includes the tag (my-app:v1.0); a missing tag means :latest. Name and tag each max 128 chars; at most two : (the second only for a registry port); digest pinning NAME@sha256:HEX is supported.
  • Link references (/...) must point into the same org — other orgs are reached only via their registry hostname, which is why they need a pull secret.

Build and push

--name NAME:TAG is required — the command aborts without a tag. Everything else follows from where the build runs: no Docker daemon on this machine or runner means --remote.

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.

image is a skill published in the GitHub repository controlplane-com/ai-plugin (11 stars, last pushed 3d ago), licensed MIT. It adds 53 tokens to every session and 4,150 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
