skill-148

skill-148 is a skill for Claude Code, Codex from legendtkl/agentic-skill-router. It costs 101 tokens per session (4,827 once invoked), scanned B, original, MIT.

A guide for using development containers: Docker-based environments that package a project’s tools and runtimes in a repeatable setup, often for VS Code.

In plain words
What is it for?
Use it to create and troubleshoot devcontainer.json files, work with container templates and features, and connect development containers with Docker Compose.
Why use it?
It helps teams use consistent project environments, isolates dependencies, and makes onboarding or rebuilding a setup easier.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is build: ./apps/frontend.

Good fit Use it to create and troubleshoot devcontainer.json files, work with container templates and features, and connect development containers with Docker Compose.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 B, and why

skill-148 scanned grade B with 1 finding 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 8d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Development Containers Expert

Expert guidance for working with Development Containers (devcontainers) - a standardized way to create fully-featured, containerized development environments.

When to Use This Skill

Activate this skill when:

  • Creating or configuring devcontainer.json files
  • Setting up containerized development environments in VS Code
  • Working with dev container Templates or Features
  • Troubleshooting devcontainer issues
  • Integrating development containers with Docker or Docker Compose
  • User mentions: devcontainers, dev containers, devcontainer.json, VS Code containers, containerized development, or development environment setup

What Are Development Containers?

A development container (dev container) is a running Docker container with a well-defined tool/runtime stack and its prerequisites. The configuration is defined in a devcontainer.json file that tells VS Code (or other supporting tools) how to access or create a development container.

Key Benefits:

  • Consistency: Same environment for all developers
  • Repeatability: Quickly recreate environments
  • Isolation: Separate tools/libraries per project
  • Onboarding: New developers get productive faster
  • CI/CD Integration: Same environment for local dev and testing

The Specification: Dev containers follow the open Development Containers Specification maintained by the devcontainers community.

Prerequisites

Required Software

  1. Docker

    • Windows: Docker Desktop 2.0+ (Windows 10 Pro/Enterprise or Windows 10 Home 2004+ with WSL 2)
    • macOS: Docker Desktop 2.0+
    • Linux: Docker CE/EE 18.06+ and Docker Compose 1.21+
  2. VS Code

    • Visual Studio Code or VS Code Insiders
    • Dev Containers extension (ms-vscode-remote.remote-containers)
  3. System Resources

    • Minimum: 1 GB RAM
    • Recommended: 2 GB RAM and 2-core CPU

Installation Steps

Windows/macOS:

  1. Install Docker Desktop from https://www.docker.com/products/docker-desktop
  2. For Windows WSL 2: Enable "Use the WSL 2 based engine" in Docker Desktop settings
  3. Install VS Code from https://code.visualstudio.com/
  4. Install the Dev Containers extension from the VS Code Extensions marketplace

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.
