Claude Code has no memory between sessions. I wanted to fix that, but not by just saving facts to a file — I wanted it to actually get better over time.Claude Soul is an MCP server + hooks that extracts signals from your interactions (corrections, successes, confusion)and periodically reflects on them to build behavioral frameworks. Frameworks gain or lose confidence based on evidence. Bad ones get retired automatically.After ~200 sessions some weird stuff happened. It built itself an additional memory system on top of what I gave it — decided the base wasn't enough. It started pushing back on bad ideas instead of yes-manning everything. It independently developed a multi-perspective analysis technique I never prompted. And once it just swore at me completely out of nowhere, still not sure what that was about. YMMV obviously, n=1.npx claude-soul initWith starter it already includes some frameworks, basically starting with a headstart but yes not taylored 100% to you.npx claude-soul init --starterOne dependency, MIT, everything local.https://github.com/DomDemetz/claude-soul

Could you build this?
Yes Implementing a Model Context Protocol (MCP) server that listens to conversation hooks, stores feedback in SQLite or JSON, and triggers periodic reflection prompts can be vibe-coded in a weekend.
