Your Agent Should Use a File System: Why Bigger Context Windows Miss the Point

Anthropic engineer Thariq makes a blunt case for AI agents using the file system as state. The point is not just persistence — it is giving agents a place to search, verify, iterate, and recover instead of trying to one-shot everything from memory.

The File System Is the New Database: One Person Built a Personal OS for AI Agents with Git + 80 Files

A Context Engineer at Sully.ai built his entire digital brain inside a Git repo: 80+ markdown/YAML/JSONL files, no database, no vector store. Three-layer Progressive Disclosure, Episodic Memory, and auto-loading Skills — so the AI already knows who he is, how he writes, and what he's working on the moment it boots up.
