asmamest/Nexus-Skills

Community-built, reusable skills for Claude Code, Codex, and AI coding agents.
Nexus Skills is an open-source library of practical skills that help AI coding agents perform engineering tasks through structured instructions, repeatable workflows, and explicit quality checks.
The goal is simple: make useful engineering knowledge reusable, discoverable, and accessible to everyone.
Why Nexus Skills?
Good agent instructions should be more than one-off prompts. They should describe a task, guide execution, account for edge cases, and define how to verify the result.
Nexus Skills brings these workflows together in a shared, community-maintained library.
- **Open:** Anyone can propose a skill or improve an existing one.
- **Reusable:** Skills follow a consistent, portable directory structure.
- **Practical:** Skills focus on real engineering tasks and verifiable outcomes.
- **Transparent:** Contributions are reviewed through public pull requests.
- **Agent-friendly:** Skills target Claude Code, Codex, and other compatible agents where supported.
Categories
Skills are organized by their primary engineering domain.
| Category | Scope |

| ai-engineering | RAG, LLM evaluation, model development, and inference |
| agentic-engineering | Agent workflows, MCP development, tool use, and evaluation |
| devops-cloud | CI/CD, containers, deployment, cloud infrastructure, and monitoring |
| security-quality | Secure coding, threat modeling, dependency auditing, and quality assurance |
