# ACIDBATH > Production AI engineering patterns for senior engineers and technical leaders. > Code-first, practitioner-focused content on agentic AI, context engineering, > and LLM cost optimization. ## What This Site Covers ACIDBATH provides deep technical content on building production AI systems: - **Agentic AI Patterns**: Sub-agent architecture, workflow prompts, orchestration - **Context Engineering**: Token optimization, progressive disclosure, semantic search - **Claude Code**: Best practices, commands, custom agents, MCP integration - **Production AI Economics**: Cost analysis, model routing, real-world benchmarks ## Recent Posts - [Claude Skills Deep Dive: Progressive Loading and the MCP Alternative](/blog/claude-skills-deep-dive): Skills load 100 tokens of metadata upfront, then instructions on-demand. Here's when to use Skills vs MCP, with working POC code. - [Single-File Scripts: When One File Beats an Entire MCP Server](/blog/single-file-scripts): Dolph is 1,015 lines of TypeScript that replace an MCP server. Here's the pattern for Bun and UV single-file scripts. - [AI Document Skills: Automated File Generation That Actually Ships](/blog/document-generation-skills): Skills generate Excel, PowerPoint, and PDF files in minutes. Complete POC code, real token numbers, and honest failure modes for production. - [Agent Architecture: From Custom Agents to Effective Delegation](/blog/agent-architecture): System prompts define agent identity. File systems enable delegation. Build specialized agents and delegate research reliably with working code. - [Context Engineering: From Token Optimization to Large Codebase Mastery](/blog/context-engineering): Progressive disclosure and semantic search: the difference between burning tokens and shipping features. Working code and hard numbers inside. ## Topics ### AI Patterns - [Claude Skills Deep Dive: Progressive Loading and the MCP Alternative](/blog/claude-skills-deep-dive): Skills load 100 tokens of metadata upfront, then instructions on-demand.
