json-config-loader

This skill configures Claude Code sandbox network isolation by setting up trusted domain whitelists and custom access policies. It helps developers secure code execution by managing environment variables and preventing unauthorized network access. Use it to implement zero-trust architecture and prevent prompt injection attacks via network controls.

This skill generates properly structured Claude Code Skills with complete YAML frontmatter, progressive disclosure documentation, and organized directory layouts. It ensures new skills follow best practices and specification requirements while creating all necessary files including SKILL.md, README.md, and process diagrams. Developers should use it when creating reusable skills to maintain consistency and compliance with Claude's skill framework.

The sandbox-configurator skill automatically configures Claude Code's execution environment with security boundaries for file system and network isolation. It enables developers to define trusted domains, manage file permissions, and control network access for secure code execution. Use this skill when you need to set up a secure, isolated sandbox for running untrusted code or building applications.

The usage-tracker skill enables developers to track and analyze tool or resource usage over time through timestamped logging and reporting. It's designed for generating periodic usage reports, monitoring quotas, and detecting usage trends, but is not suitable for real-time or high-frequency event tracking. Key capabilities include daily/weekly/monthly breakdowns and pattern analysis for building dashboards.
