Transform Your AI Coding Workflow with ECC Tools

The landscape of AI-assisted software development has evolved dramatically. What started as simple code completion has become a sophisticated ecosystem of intelligent agents, skills, and automated workflows. At the forefront of this transformation stands Everything Claude Code (ECC), an open-source project that has garnered over 77,000 GitHub stars and become the backbone of modern AI agent harnesses.

What is ECC Tools?

ECC Tools is the comprehensive open agent harness system designed to enhance AI code assistants like Claude Code, Codex, Cursor, and OpenCode. Built by Affaan Mustafa and awarded as an Anthropic hackathon winner, ECC provides a complete ecosystem of skills, agents, memory optimization, continuous learning, and security scanning.

116+ skills teach your AI assistant about frameworks, patterns, and best practices. 28 specialized agents handle complex tasks like code review, security analysis, and test generation. 57 commands provide instant access to workflows, and 102 security rules keep your AI sessions safe with AgentShield.

Key Features That Transform Development

• Skills & Knowledge Domain-specific knowledge files that teach Claude Code, Codex, OpenCode, and Cursor about frameworks, patterns, and best practices. Auto-load based on context.
• Specialized Agents Subagents for complex tasks: code review, security analysis, test generation, and more. Each agent has focused expertise.
• Hooks Automated behaviors that trigger before or after tool calls. Auto-format code, run checks, prevent mistakes.
• Continuous Learning The instinct system observes how you work and creates reusable patterns with confidence scores. Over time, your agent workflow adapts to your style.
• AgentShield Security A security auditor for AI agent configurations. Uses an Opus 4.6-powered pipeline to catch prompt injection, data exfiltration, and privilege escalation vectors.

Cross-Platform Compatibility

ECC works seamlessly across multiple AI coding assistants—Claude Code, Codex, Cursor, and OpenCode—making it a universal layer for your development workflow. Whether you prefer the CLI approach or the IDE integration, ECC adapts to your setup.

The selective install builder lets you pick profiles (core, developer, security, or full) to install only what your team needs. Choose core for essential workflows, developer for enhanced productivity, security for threat protection, or full for everything.

GitHub App Integration

The ECC Tools GitHub App turns your repository history into reusable skills and defaults. Comment /ecc-tools analyze on any issue, and ECC inspects workflow patterns, repo conventions, and risky config surfaces without changing your merge process.

Free on public repositories, then $19 per active seat for private repo coverage, pooled installation usage, and deeper scanning. Enterprise plans available for organization-wide rollout.

Security First with AgentShield

AgentShield runs 102 security rules with 98% test coverage. The red-team/blue-team/auditor pipeline catches prompt injection, data exfiltration, and privilege escalation vectors before they become problems.

Run it locally with npx ecc-agentshield scan ./CLAUDE.md or automate it through the GitHub App for every pull request. The security report includes severity ratings, specific findings, and remediation steps.

Getting Started

Ready to transform your AI coding workflow? Install the GitHub App for the fastest repo-level setup, or use the selective install builder for local harnesses. The open-source repository stays MIT-licensed—completely free to copy, modify, and distribute.

With ECC, your AI coding assistant learns your team’s patterns, follows your conventions, and evolves with your codebase. Every session builds on the previous one, turning raw AI power into team-specific productivity.
