How Hook-Based Memory Systems Prevent Vendor Lock-In Across AI Coding Harnesses
By

Front-window bakery material. Catches the eye, delivers the goods.
Summary
The article discusses the debate around vendor lock-in in AI coding tools, focusing on how different harnesses (agent loops, tool definitions, context management, memory, prompts, and workflows) wrap around LLMs to create useful products. It highlights that memory is the sharpest edge of the lock-in debate, and explores how hook implementations using Neo4j can give persistent memory across tools like Claude Code, Codex, and Cursor without locking users into any single platform.
Key quotes
· 5 pulledThe main debate isn't about when the next better model drops, but about who will build the right harness around them.
A harness is the scaffolding around the model: the agent loop, tool definitions, context management, memory, prompts, and workflows that turn a raw LLM into a useful product.
The model is the engine, the harness is everything that makes it actually drive.
Memory is the sharpest edge of this [vendor lock-in debate].
Hook implementation gives Claude Code, Codex, and Cursor persistent memory via Neo4j, without locking you into any one of them.
