Minion: Open-Source Agent Framework Tracking What Frontier Labs Ship

It's an open-source agent framework tracking and implementing what frontier labs are actually shipping. A few things that might interest your readers:

• CodeAct / PTC — code execution as the primary action space, aligned with Anthropic's Programmatic Tool Calling approach

• TST (Tool Search Tool) — based on Anthropic's Advanced Tool Use research. Instead of loading all tool definitions upfront, agents discover tools on-demand. Result: 85% token reduction, and tool selection accuracy improves from 49% → 74% on Opus 4.

• Auto-compact — when >90% context threshold approach, auto triggers compact.

• Auto-decay — oversized tool responses auto-offloaded to file with configurable TTL.

• Skills + MCP — modular, reusable agent behaviors with full MCP support
