Everything Claude Code (ECC) is a plugin you install through the Claude Code marketplace that bundles 63 agents, 249 skills, 79 commands, hooks, MCP server configs, and security enforcement scripts into one harness. The pitch is: stop hand-rolling your CLAUDE.md and skills, install this and get a curated set that actually works.

It's MIT licensed and works across Claude Code, Cursor, OpenCode, and Codex, not just Claude. The agents cover the usual suspects (code review, security analysis, planning, language-specific reviewers) and the skills span TDD, video editing, and dozens of niche workflows. Hooks auto-execute on editor events. The security scanning piece tries to catch prompt injection and rule violations before they hit your codebase.

Solo devs and small teams using AI coding agents get the biggest lift here. Pulling in 63 agents you didn't ask for is overkill, but cherry-picking the ones that match your workflow is the real value. Large teams will probably want to fork it and trim aggressively.

The catch: 249 skills is a lot of surface area to audit. You're trusting someone else's prompt engineering to run inside your editor. Read the security-relevant pieces before you turn the hooks on, and treat this as a starting template, not gospel.
