Building a shared memory system for Codex and Claude Code to save Astra usage
The author kept re-explaining the same project to new agents while using GPT-6 Astra, so they built a cross-tool shared memory system and compared simple rules against a trained memory model.
you’re burning through your gpt-6 astra usage explaining the same f**king project to a new agent. the fix: build a shared memory system for codex and claude code. save your decisions, corrections, and commands that work. both tools can then find and use this information. correct an old command in codex. claude code can use the corrected command in your next session. teach it once. use it in the next task. i used kimi k3 to build the system. then i compared simple rules with a trained memory model. in my tests, the rules worked nearly as well as the trained model. the full guide, code, and test results are below:
