Score: 6.3/10 (Innovation: 6, Technical: 7, Documentation: 7, Utility: 5)

KeepPlain is a cross-agent session persistence and sharing tool that captures coding agent histories (Claude Code, Codex, Cursor, Pi, Antigravity) and lets agents search and resume past sessions, surface recurring mistakes as rules, and hand off between agents when rate limits hit. It adds novel utilities like agent-session blame and a public library of solved sessions, with careful privacy handling such as local secret redaction. The plugin is MIT while the backend is proprietary.

Target audience: AI-assisted software developers and engineering teams
