Claude Code with ECC

See how ECC transforms your Claude Code experience.

Without ECC
  • Claude Code doesn't know your team's patterns
  • Manual test writing with inconsistent coverage
  • Security vulnerabilities slip through reviews
  • No shared coding standards across the team
  • Every session starts from scratch
With ECC
  • Skills teach Claude Code your exact conventions
  • TDD workflow enforces 80%+ test coverage
  • AgentShield catches config vulnerabilities
  • Shared skills and agents across the whole team
  • Continuous learning evolves with your codebase

Choose Your Path

ECC offers two complementary products: an automated GitHub App for skill generation and an open-source repository of skills, agents, and hooks.

Open Source

What ECC Tools Does

Your repository has implicit knowledge—patterns, conventions, and workflows that live only in git history. ECC Tools extracts them and makes them explicit.

Pattern Detection

Analyzes commit history with Claude AI to detect coding conventions, architectural patterns, and implicit team standards.

Skill Generation

Creates SKILL.md files in the Claude Code format that automatically load when working in your repository.

Instinct Creation

Generates atomic instincts for the continuous-learning-v2 system. Small, confidence-weighted behaviors that evolve.

Workflow Discovery

Identifies recurring processes like migrations, deployments, and feature patterns your team performs unconsciously.

Four steps to smarter AI assistance

1

Install the GitHub App ~10 sec

Grant ECC Tools read access to git history and write access to create PRs. That's all we need.

2

Trigger Analysis ~5 sec

Comment /ecc-tools analyze on any issue. We analyze up to 500 commits with Claude AI.

3

Review the Pull Request ~2 min

A PR is created with your SKILL.md and instincts.yaml files. Review the detected patterns and merge.

4

Claude Code Learns automatic

Skills auto-load when you work in the repo. Import instincts with /instinct-import for evolving behaviors.

Built for Every Developer

Whether you're solo or on a team, ECC Tools adapts to your workflow.

3
Audit with AgentShield (optional)

Run npx ecc-agentshield audit .cursorrules to verify your configs are secure.

1
Install the universal package

The installer detects OpenCode and creates .opencode/ configs automatically.

$ npm i -g ecc-universal
2
Open OpenCode in your project

Skills auto-load from the generated config files. All ECC skills and agents are available immediately.

3
Run AgentShield audit (optional)

Run npx ecc-agentshield audit .opencode/ to verify your configurations are secure.

1
Install the universal package

Codex picks up CLAUDE.md and skill files from your project root.

$ npm i -g ecc-universal
2
Run Codex in your project

Codex reads CLAUDE.md and all skill files automatically. Coding standards and patterns apply out of the box.

3
Run AgentShield audit (optional)

Run npx ecc-agentshield audit ./CLAUDE.md to verify your configurations are secure.

AgentShield

Security auditor for AI agent configurations. Catch misconfigurations before they reach production.

AgentShield NEW

A security auditor for AI agent configs—CLAUDE.md, .cursorrules, agents.json, and more. 102 rules, 1,282 tests, 98% coverage. AgentShield runs an Opus 4.6 red-team / blue-team / auditor pipeline to stress-test your configurations, identify prompt injection vulnerabilities, and verify guardrails before deployment.

Red Team Blue Team Auditor

Config Scanner

Scans CLAUDE.md, .cursorrules, agents.json, and custom configs for security weaknesses and misconfigurations.

Injection Detection

Red-team agent crafts adversarial prompts to test for injection vulnerabilities in your agent instructions.

Guardrail Verification

Blue-team agent validates that safety boundaries, permission scopes, and tool restrictions are properly enforced.

Audit Report

Generates a structured security report with severity ratings, specific findings, and remediation steps.

What Developers Are Saying

From solo hackers to teams, developers are using ECC to supercharge their Claude Code workflows.

Are you cogsec? You taught me how to Claude Code. I shared your articles with my friends and we all used the plugin to get started—we made it to this hackathon because of it. Keep writing and improving the repo.

DV
Developer at Claude Code’s 1st Birthday Cerebral Valley Hackathon Attendee

I was worried about using other people’s configs—until he showed me AgentShield. The red-team audits in the PRs, the commit history, the 1,282 tests. Now I trust it more than configs I’d write myself.

SE
Security-Conscious Developer Cerebral Valley Hackathon Attendee

I watched Affaan build this from scratch—the agents, the skills, the whole ecosystem. It genuinely makes Claude Code better. I use it on every project now.

Frequently Asked Questions

Quick answers to common questions about ECC Tools.

ECC Tools is the automated GitHub App that analyzes your repository's git history using AI and generates skill files. Everything Claude Code is the open-source repository of pre-built skills, agents, hooks, and the continuous learning system. They're complementary: ECC Tools generates custom skills from your codebase, while ECC provides battle-tested community configs you can use immediately.
The free tier gives you 10 analyses per month per repository. The open-source Everything Claude Code repository is completely free and MIT-licensed—you can copy, modify, and distribute any skills, agents, or hooks without limits. For heavier usage of the GitHub App, check the pricing page.
The GitHub App requests read access to git history (commits, diffs, and branch info) and write access to create pull requests. It does not access secrets, environment variables, or any data outside the repository. All analysis runs through Claude AI and results are delivered as a PR for your review before anything is merged.
The fastest way is the universal installer: npm i -g ecc-universal. This installs all skills, agents, and hooks for Claude Code, OpenCode, and Cursor. Alternatively, you can copy individual files from the GitHub repository into your project's .claude/ directory.
AgentShield is a security auditor for AI agent configurations like CLAUDE.md, .cursorrules, and agents.json. It uses an Opus 4.6-powered pipeline with three stages: a red team that crafts adversarial prompts, a blue team that validates guardrails, and an auditor that produces a scored security report. Run it with npx ecc-agentshield audit ./CLAUDE.md.
Absolutely! Everything Claude Code is MIT-licensed and contributions are welcome. Fork the repository, add your skill or agent following the existing format, and open a pull request. The community reviews and tests contributions, and popular ones get featured in the showcase.
