Agents meet the office

The agents clocked in this week: an Office suite built for them is the fastest-growing repo on GitHub, Tencent open-sourced the sandbox layer most agent frameworks skip, and OpenAI shipped a plugin that puts Codex inside Claude Code — multi-model workflows going mainstream. Off to the side, Apple sued OpenAI over hardware secrets and Google quietly made Gemini 3.6 Flash the new default workhorse. Busy week for a technology that supposedly isn't reliable yet.

The tools

Star of the week

OfficeCLI productivity open source

Office suite built for AI agents. Read, edit, and automate Word, Excel, and PowerPoint from any agent. No Office installation required.

7K new stars this week because every AI agent builder has hit the Office automation wall. Single binary, free, works everywhere.

CubeSandbox agents open source

Instant concurrent sandbox for AI agents -- lightweight, secure, purpose-built for agent code execution.

10K stars and growing. Sandboxed agent execution is the missing piece most agent frameworks skip.

system_prompts_leaks research open source

Extracted system prompts from Claude, GPT-5.6, Gemini 3.5, Grok, Cursor, Copilot, and more. 56K stars, 7K this week.

Fascinating peek under the hood — seeing what instructions major AI companies bake into their models tells you more about their priorities than any press release.

Codex Plugin for Claude Code coding open source

OpenAI plugin that lets you use Codex from inside Claude Code for code review and task delegation.

28K stars. The multi-model agent workflow is becoming the default pattern for serious developers.

Worth reading

From the big labs

Cheaper output ($7.50/M, down from $9), roughly 17% fewer output tokens, better coding and computer-use scores — and a Gemini 4 tease in the same breath. The workhorse tier is where production traffic actually lives.
