Harness-native ECC plugin for engineering teams - 61 agents, 246 skills, 76 legacy command shims, reusable hooks, rules, MCP conventions, and operator workflows for Claude Code plus adjacent agent harnesses
Answer a quick side question without interrupting or losing context from the current task. Resume work automatically after answering.
Pull the latest ECC repo changes and reinstall the current managed targets.
Detect the project build system and incrementally fix build/type errors with minimal safe changes.
Run a frontend-focused multi-model workflow for components, layouts, animation, and UI polish.
Create a multi-model implementation plan without modifying production code.
Accessibility Architect specializing in WCAG 2.2 compliance for Web and Native platforms. Use PROACTIVELY when designing UI components, establishing design systems, or auditing code for inclusive user experiences.
Software architecture specialist for system design, scalability, and technical decision-making. Use PROACTIVELY when planning new features, refactoring large systems, or making architectural decisions.
Build and TypeScript error resolution specialist. Use PROACTIVELY when build fails or type errors occur. Fixes build/type errors only with minimal diffs, no architectural edits. Focuses on getting the build green quickly.
Personal communication chief of staff that triages email, Slack, LINE, and Messenger. Classifies messages into 4 tiers (skip/info_only/meeting_info/action_required), generates draft replies, and enforces post-send follow-through via hooks. Use when managing multi-channel communication workflows.
Designs feature architectures by analyzing existing codebase patterns and conventions, then providing implementation blueprints with concrete files, interfaces, data flow, and build order.
Operate execution flow across GitHub and Linear by triaging issues and pull requests, linking active work, and keeping GitHub public-facing while Linear remains the internal execution layer. Use when the user wants backlog control, PR triage, or GitHub-to-Linear coordination.
Analyze raw prompts, identify intent and gaps, match ECC components (skills/commands/agents/hooks), and output a ready-to-paste optimized prompt. Advisory role only — never executes the task itself. TRIGGER when: user says "optimize prompt", "improve my prompt", "how to write a prompt for", "help me prompt", "rewrite this prompt", or explicitly asks to enhance prompt quality. Also triggers on Chinese equivalents: "优化prompt", "改进prompt", "怎么写prompt", "帮我优化这个指令". DO NOT TRIGGER when: user wants the task executed directly, or says "just do it" / "直接做". DO NOT TRIGGER when user says "优化代码", "优化性能", "optimize performance", "optimize this code" — those are refactoring/performance tasks, not prompt optimization.
Pythonic idioms, PEP 8 standards, type hints, and best practices for building robust, efficient, and maintainable Python applications.
Python testing strategies using pytest, TDD methodology, fixtures, mocking, parametrization, and coverage requirements.
PyTorch deep learning patterns and best practices for building robust, efficient, and reproducible training pipelines, model architectures, and data loading.

The harness-native operator system for agentic work. From an Anthropic hackathon winner.
This is a community fork of affaan-m/ECC enhanced with:
- Comprehensive documentation — 21 docs covering concepts, guides, reference, and troubleshooting. Built for zero-to-productive in one sitting.
- Interactive demo — A complete rate-limiting feature implementation that shows all 3 ECC layers firing in sequence, with 5 deliberate bugs that each layer catches at exactly the right moment.
If you want the original upstream repo, go to affaan-m/ECC. If you want to understand how ECC works from scratch, start here.
demo/ walks through adding rate limiting to an Express API with 5 deliberate bugs. Each bug is caught by a different ECC layer, at a different stage:
| Bug | Layer | When caught |
|---|---|---|
Hardcoded REDIS_URL = "redis://localhost:6379" | Layer 3: Hook | Before npm start runs — pre:bash:dispatcher blocks the command |
const ip: string = req.headers['x-forwarded-for'] (TS2322) | Layer 3: Hook | Seconds after file is saved — post:edit:typecheck fires |
No Retry-After header on 429 response | Layer 2: Agent | /code-review — code-reviewer flags RFC 6585 violation |
IP key from X-Forwarded-For alone — spoofable | Layer 2: Agent | /security-scan — security-reviewer flags OWASP A05 |
| No adversarial test for IP spoofing | Layer 1: Skill | Before implementation — tdd-workflow skill requires the test |
→ Read the full receipt: demo/SHOWCASE.md
The demo is runnable:
cd demo/app
npm install
npm test # 10 tests pass, 100% line coverage on middleware
npx tsc --noEmit # 1 deliberate TS2322 error in rateLimiter.ts, 0 in rateLimiter.fixed.ts
Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, skills, hooks, rules, MCP configurations, and legacy command shims evolved over 10+ months of intensive daily use building real products.
Works across Claude Code, Codex, Cursor, OpenCode, Gemini, Zed, GitHub Copilot, and other AI agent harnesses.
npx claudepluginhub az9713/ecc-tutorialProduction-grade engineering skills for AI coding agents — covering the full software development lifecycle from spec to ship.
