The insight here is spot-on: frameworks solve problems you don't have yet.
But here's the nuance I'd add — what you built is a framework. It's just a transparent one. MEMORY.md, SOUL.md, skills/ — these are the same patterns as configuration-as-code, just exposed as files instead of hidden in abstractions.
I've written about this from the other angle: agent behavior living in .claude/ or SKILL.md files. The pattern isn't "no framework" — it's "framework as readable code."
The real win isn't avoiding frameworks entirely. It's keeping the framework inspectable. When your agent makes a decision, you can trace it back to MEMORY.md or 2026-03-31.md. That's the feature.
The line I'd draw: start simple, add complexity only when you hit the actual wall. Not because you read a blog post about RAG pipelines.
Great piece.
