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 is Everything Claude Code (ECC), an open-source project that has amassed over 77,000 GitHub stars and has become the backbone of modern AI agent harnesses.
What is ECC Tools?
ECC Tools is the complete open agent harness system designed to enhance AI coding assistants like Claude Code, Codex, Cursor, and OpenCode. Created by Affaan Mustafa and awarded as the winner of the Anthropic hackathon, ECC provides a comprehensive ecosystem of skills, agents, memory optimization, continuous learning, and security.
116+ skills teach your AI assistant frameworks, models, 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 protect your AI sessions with AgentShield.
Key Features That Transform Development
- Skills & Knowledge Domain-specific knowledge files that teach Claude Code, Codex, OpenCode, and Cursor the frameworks, models, and best practices. Automatic loading based on context.
- Specialized Agents Sub-agents for complex tasks: code review, security analysis, test generation, and more. Each agent has targeted expertise.
- Hooks Automated behaviors that trigger before or after tool calls. Auto-formatting of code, running checks, error prevention.
- 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 a pipeline powered by Opus 4.6 to detect prompt injection, data exfiltration, and privilege escalation vectors.
Multi-Platform Compatibility
ECC works seamlessly with multiple AI coding assistants—Claude Code, Codex, Cursor and OpenCode—making this a universal layer for your development workflow. Whether you prefer the CLI approach or IDE integration, ECC adapts to your setup.
The selective installation builder allows you to choose profiles (core, developer, security, or full) to install only what your team needs. Choose core for essential workflows, developer for increased productivity, security for protection against threats, or full for everything.
GitHub App Integration
The ECC Tools GitHub App transforms your repository's history into reusable skills and settings. Comment /ecc-tools analyze on any issue, and ECC inspects workflow patterns, repository conventions, and risky configuration surfaces without altering your merge process.
Free on public repositories, then $19 per active seat for private repository coverage, grouped installation usage, and in-depth analysis. Enterprise plans available for organization-wide deployment.
Security First with AgentShield
AgentShield runs 102 security rules with 98% test coverage. The red-team/blue-team/auditor pipeline detects prompt injection, data exfiltration, and privilege escalation vectors before they become issues.
Run it locally with npx ecc-agentshield scan ./CLAUDE.md or automate it via the GitHub App for each pull request. The security report includes severity ratings, specific findings, and remediation steps.
To Start
Ready to transform your AI coding workflow? Install the GitHub App for the fastest repository-level setup, or use the selective installation builder for local harnesses. The open-source repository remains licensed MIT—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. Each session builds on the previous one, transforming the raw power of AI into productivity specific to your team.
