Harness race: Claude Code mods; Grok Bot goes software-first
From the AI digest for Oct 1, 2026
Sources mods thread Grok Bot sama
- Claude Code "mods" (~2:58 PM ET X layer): user-authored TypeScript mods changing behavior/UI/features, a community marketplace (
anthropics/claude-plugins-community), Claude writing mods on prompt (Addy Osmani post), forked per-turn agents as a mod pattern. Anthropic's extension-layer answer to OpenClaw's plugins/skills — watch the security surface a marketplace becomes. - Grok Bot build features: hand-off to Cursor, PR management via GitHub/Origin plugins, shared video demos, "major speed improvements," and proactivity that reads connectors (the switched-flight → ping-your-Uber demo). SpaceXAI also made its engineering team's bots public, and the self-demonstration loop keeps running: "SpaceXAI is using Grok Bot to build Grok Bot."
- Model-layer numbers (vendor-adjacent): Siqi Chen's internal cfo.ai eval — 6.1 Sol 3× the efficiency of Opus 5.5 and 2.5× Sonnet 5.5, after Opus 5.5 had been 2× vs gpt-6-sol; sama: 6.1 Sol "our fastest-growing model ever... was a bit slow under load. Should be much better now."
