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.
ECC Tools
Automated skill generation. Install the GitHub App, comment /ecc-tools analyze on any issue, and receive a PR with SKILL.md and instincts extracted from your git history.
Everything Claude Code
The ecosystem of skills, agents, hooks, and the continuous-learning system. Copy what you need, customize for your workflow, contribute improvements back.
Browse RepositoryEverything in One Package
npm i -g ecc-universal installs the full ecosystem for Claude Code, OpenCode, and Cursor.
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
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.
Trigger Analysis ~5 sec
Comment /ecc-tools analyze on any issue. We analyze up to 500 commits with Claude AI.
Review the Pull Request ~2 min
A PR is created with your SKILL.md and instincts.yaml files. Review the detected patterns and merge.
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.
Solo Developers
Install ecc-universal and instantly get battle-tested skills, agents, and hooks. No configuration needed.
Engineering Teams
Generate skills from your team's git history. Share conventions, enforce standards, and onboard new members faster.
Open Source Maintainers
Help contributors follow your project's conventions automatically. Skills load when contributors open Claude Code in your repo.
Security-Conscious Teams
Use AgentShield to audit AI agent configs before deployment. Catch prompt injection vulnerabilities and misconfigured guardrails.
Get Started in 30 Seconds
Choose your tool and follow the steps.
The fastest way to get all skills, agents, hooks, and continuous learning.
Or universal: npm i -g ecc-universal
Try /tdd, /plan, /code-review, /e2e, /security-review, or /build-fix.
Run /continuous-learning-v2 to let Claude Code observe your workflow and create atomic instincts.
Grant read access to git history and write access for PRs. No code access needed.
Type /ecc-tools analyze on an issue in your repo. The app analyzes up to 500 commits.
Review the generated SKILL.md and instincts.yaml, then merge. Claude Code picks them up automatically.
The installer detects Cursor and creates .cursorrules with equivalent configurations.
Rules from .cursorrules are automatically loaded. Apply coding standards, patterns, and constraints.
Run npx ecc-agentshield audit .cursorrules to verify your configs are secure.
The installer detects OpenCode and creates .opencode/ configs automatically.
Skills auto-load from the generated config files. All ECC skills and agents are available immediately.
Run npx ecc-agentshield audit .opencode/ to verify your configurations are secure.
Codex picks up CLAUDE.md and skill files from your project root.
Codex reads CLAUDE.md and all skill files automatically. Coding standards and patterns apply out of the box.
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.
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.
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.
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.
