I built Codemate — a multi-agent coding assistant with memory and mistake learning

I’ve been building **Codemate**, an open-source coding assistant focused on making AI coding workflows more reliable. Core features: * **Multi-agent workflow**: planner, research, coder, tester, reviewer, and writer work as separate roles. * **TaskGraph planning**: complex requests are broken into structured steps before coding starts. * **Testing and review loop**: implementation, verification, review, retry, and self-check are part of the flow. * **Mistake learning**: when Codemate fixes an error or discovers a useful pattern, it can save that as a reusable lesson for future runs. * **Memory system**: * `supermemory` for user preferences and explicit “remember this” notes * `lessons` for reusable engineering rules and mistakes to avoid * `changelog` for recent project history * **Drift detection**: long tasks are checked against the original goal to avoid going off-track. * **Persistence writer**: after a run, Codemate records what changed and what should be remembered. The goal isn’t to replace developers. It’s to make coding agents better at long tasks, refactors, testing, and project maintenance. Install ：npm install -g @codemate-ai/cli
