Microsoft Research and UC Berkeley open-source TokenEconomizer, a plugin that cuts Claude Code and Codex costs by 18.4–30.9% on SWE-Bench without changing the agent
Microsoft Research, Microsoft Security and UC Berkeley open-sourced TokenEconomizer on GitHub (Apache 2.0, v0.1.0 released October 26), a plugin for Claude Code, Codex, GitHub Copilot CLI and Pi, with experimental opencode support. It learns from earlier sessions in the same repository: micro-skills remember repo facts, tool pruning drops tool definitions that go unused, and a loop guard nudges an agent that is stuck. The paper reports 18.4–30.9% lower mean cost across five agent and model combinations on 277 SWE-Bench tasks (paper figures).

Autonomous open-sources OpenHarness: one control plane for Claude Code, Codex, and domain-specific harnesses
Autonomous (@autonomous_labs) open-sourced OpenHarness (github.com/autonomous-ai/openharness): not another coding agent, but a harness control plane that runs Claude Code, Codex, Cursor, OpenCode, Pi, Command Code, Devin, Grok Build, and more in persistent tmux sessions across machines. Domain-Specific Harnesses target CAD, PCBs, robotics, and games; a desktop app plus open-hardware Harness units shipped the same week. Credentials stay in each vendor’s local config; machines link via outbound-only daemons with end-to-end encrypted relay/WebRTC.

Hypernovum turns Obsidian project notes into a 3D city and launches coding agents
@DanKornas introduced Hypernovum, a desktop-only Obsidian plugin that maps project notes into a live 3D city using frontmatter, Git signals, and vault links. From one view you can launch Claude Code, Codex, Antigravity CLI, or a custom command, and inspect branch, commit velocity, dirty trees, stale projects, and merge conflicts. It is open source under AGPL-3.0.
