Agent memory as a file format

Memoryfields - a vastly simpler way to do agent memory

This is an interesting take on Agent memory as a portable file format from Cal Paterson. Essentially he’s proposing a file format which looks like this:

my-memories.memoryfield.zip
- carbon-fibre-woks.md
- finnish-bureaucracy-tips.md
- wec-2026-season-notes.md
- nomic-embed-text-v1.5.sqlite3

Agents write memories to markdown files with optional YAML frontmatter, and an optional generated SQLite vector index lets them search across those memories semantically.

The specification is on GitHub and is pretty well thought-out, and there’s also an Agent Skill and a Python CLI tool for interacting with memories.
