Agent Kernel is a minimalist framework that gives AI agents persistent state using just three Markdown files — one for memory, one for plans, and one for context. No database, no complex infrastructure. Works with any LLM provider and keeps agent state human-readable and version-controllable.

Reviewer scorecard
“The simplicity is the feature. Three Markdown files, git-trackable, human-readable. No ORM, no migrations, no database to manage. For agents that need persistent state without infrastructure overhead, this is the pragmatic choice. I would pick this over LangGraph's complexity any day.”
“The best GraphQL server for Node.js. Envelop plugin system and multi-runtime support (Bun, Deno, Workers).”
“Agent Kernel proves that the best agent infrastructure might be no infrastructure at all. Markdown as a universal state format means your agent's memory is inspectable, debuggable, and portable. This "files over frameworks" philosophy will age well.”
“GraphQL servers are mature technology. Innovation has moved to the client and tooling layer.”
“Cute for prototyping but falls apart at any real scale. No concurrent access handling, no structured queries over memory, no way to prune state as it grows. You will outgrow three Markdown files the moment your agent needs to remember more than a weekend's worth of conversations.”
“If you're building a GraphQL API in Node.js, Yoga with Envelop plugins is the most maintainable approach.”
