Dolph is 1,015 lines of TypeScript that replace an MCP server. Here's the pattern for Bun and UV single-file scripts.

Skills load 100 tokens of metadata upfront, then instructions on-demand. Here's when to use Skills vs MCP, with working POC code.

Skills generate Excel, PowerPoint, and PDF files in minutes. Complete POC code, real token numbers, and honest failure modes for production.

The workflow section drives 90% of the value in agentic prompts. Learn to build workflow prompts that work, when they fail, and how to measure ROI.

System prompts define agent identity. File systems enable delegation. Build specialized agents and delegate research reliably with working code.

Turn your file system into an AI interface. Build drop zones that process files automatically with working Python code and production considerations.

Progressive disclosure and semantic search: the difference between burning tokens and shipping features. Working code and hard numbers inside.
