How do I install Everything Claude Code on Windows?

Use the PowerShell script (install.ps1) with language flags, but note that manual rule copying is still required as plugins can't distribute rules automatically due to Claude Code limitations.

Everything Claude Code vs simple config files for AI agents?

ECC offers a complete system with agents and learning capabilities, but for teams wanting lightweight, custom configurations without the complexity, standalone configs might be more flexible and easier to maintain.

Can I use ECC with a custom LLM gateway?

Yes, it works with custom endpoints via Claude Code's CLI settings, but you must configure model routing externally as ECC doesn't hardcode provider specifics.

How to disable specific hooks in Everything Claude Code?

Set the ECC_DISABLED_HOOKS environment variable with comma-separated hook IDs, allowing runtime gating without editing files, as detailed in the hook runtime controls section.

Does Everything Claude Code support Java or Kotlin development?

Yes, it includes agents and skills for Java, Kotlin, and Spring Boot, but installation requires selecting those languages during setup, which adds to the initial complexity.

What's the difference between skills and commands in ECC?

Skills are the primary workflow surface with reusable patterns, while commands are legacy shims; new development should use skills, but both are maintained for compatibility during migration.
