What it does

Containerizing Applications is an agent skill from aiskillstore/marketplace. Containerizes applications with Docker, docker-compose, and Helm charts. Use when creating Dockerfiles, docker-compose configurations, or Helm charts for Kubernetes. Includes Docker Hardened Images (95% fewer CVEs), multi-stage builds, and 15+ battle-tested gotchas.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/production-security.md`, `scripts/verify.py` and `skill-report.json`).

It sits in DevOps & Cloud, covering Containers and Container orchestration. It works with Docker, Helm, Kubernetes and FastAPI. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Creating Dockerfiles
  • Docker-compose configurations
  • Helm charts for Kubernetes

Example prompts

  • “Use the containerizing-applications skill to containeriz applications with Docker, docker-compose, and Helm charts”
  • “/containerizing-applications”

Requirements

  • Python 3
  • Node.js
  • Docker
  • A credential in NPM_TOKEN

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Browser vs Server URLs
  2. Healthcheck IPv6 Issue
  3. MCP Server 421 Misdirected Request
  4. SQLModel Tables Not Created
  5. Database Migration Order
  6. uv Network Timeout
  7. Missing Syntax Directive
  8. localhost in Container
  9. Auth Origins
  10. Service Startup Order
  11. Health Check Timing
  12. pgAdmin Email Validation

What it can do on your machine

Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • helm
    • docker
    • wget
    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use helm, docker and wget, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NPM_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Containerizing Applications loads about 1.9k tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 320 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 320 words (~1,864 tokens).
