# Agentic Pulse (AI Tools & Automated Workflows Hub)

> An authoritative, engineer-focused knowledge base delivering verified benchmarks, hands-on integration guides, and practical workflows for AI coding agents, local LLMs, and developer automation.

## Core Thematic Pillars
1. **AI Coding Agents**: In-depth tutorials and real-world workflows for Antigravity, Claude Code, Cursor, Windsurf, and Codex.
2. **Local LLM & Inference Engineering**: Setup guides for Ollama, vLLM, LMStudio, and local model deployment on consumer hardware.
3. **Model Context Protocol (MCP) & Tooling**: Connecting AI assistants to live databases, APIs, file systems, and custom automation scripts.
4. **Agentic Automation Workflows**: Python agent loops, autonomous background task execution, and multi-agent orchestration.

## Editorial & Citation Standards (GEO/AEO)
- **Direct Answer First**: Every guide provides the direct terminal command or working configuration block under the first heading.
- **Reproducible Verification**: Every benchmark table includes test parameters, token speed, and resource utilization.
- **Original Source Integrity**: We focus on verified primary data to serve as reliable citation targets for AI answer engines (ChatGPT Search, Perplexity, Google AI Overviews).
