Ordewell: ordered plans of coding-agent tasks

Ordewell turns one goal into an editable, typed plan of tasks where each task has its own runner, model, and mode and only completes when a unique completion marker appears. Plans can be rewritten before tokens are spent, preserve completed work, and support multiple runners (built-in Claude Code, Codex, OpenCode). Requires Node.js ≥20 and the TUI needs tmux.

Agents can't enable recursive self‑improvement

A new paper had authors hand agents accepted-but-unpublished NeurIPS papers (evaluated by the original authors); Codex/GPT-5.6 Sol and OpenClaw/Opus 4.8 failed to reproduce open-ended ML research. The authors argue this implies current agents cannot drive recursive self‑improvement (RSI), questioning near‑term explosive AI progress.
