Claude Code can now self-improve with this plugin. Introducing claude-smart — an open-source plugin that helps Claude Code learn from every session. Memory helps Claude Code remember what happened. claude-smart helps Claude Code improve what it does next. Example: Claude Code runs `npm test` without `--run`, and the command hangs in your repo. Memory stores: “npm test kept hanging.” claude-smart learns: “When running tests in this repo, use `npm test -- --run` because default watch mode hangs.” claude-smart’s learnings are reusable and actionable, even across different projects. It can also reduce unnecessary planning iterations and token use by 70%+ on similar future tasks. Runs locally. 100% open source. No data is shared. Install: npx claude-smart install With Codex: npx claude-smart install --host codex GitHub:
