This is an educational repository of Python scripts, mini-projects, and markdown guides for building LLM-based AI agents applied to cybersecurity. The code is organized into five progressive parts: foundational LLM/embeddings usage, prompt templates, prompt chaining, RAG over security data, and agentic workflows. It demonstrates multiple agent frameworks (LangChain, LangGraph, CrewAI, DeepAgents) and MCP server integrations for tools like nmap and Shodan. The dominant character is application/tutorial code rather than data research, although it bundles small datasets (CVE embeddings, sample RAG corpora) and commits Chroma vector stores for offline exercises. The repo is not a single deployable service; it is a collection of entry-point scripts and small frameworks. Architecture is a set of standalone examples with shared patterns: state graphs for orchestration, YAML-configured crews, MCP adapters, and RAG ingestion/query pipelines. Most scripts require OpenAI-compatible API keys and/or local tools such as nmap/Ollama. Simulated data and placeholder responses in some examples make it a learning environment rather than production security tooling. Maintenance is current but drift is moderate: some examples use deprecated langchain vectorstore imports, documentation is duplicated across subdirectories, several referenced files are missing, and hardcoded model strings like gpt-5.4-mini appear dated or fictional. There is no root-level automated test suite; only the Shodan MCP subproject contains tests. The strongest reusable patterns are the MCP server wrapping, LangGraph conditional-state orchestration, CrewAI declarative crew configuration, and the hierarchical SOC agent supervisor.
