Agent Tools Today, 29 Oct 2026: Gemini 4 Carbon, Copilot Connectors, OpenCode Goals

Google announced Gemini 4 Carbon on 28 Oct 2026, describing it as "our strongest model with state-of-the-art cybersecurity and long horizon capabilities," with introductory pricing of $2 per million input tokens and $10 per million output tokens, released first to a subset of cyber defenders before trusted partners via the Fairwind Program and developers later. The same day, GitHub began rolling out GitHub verified MCP servers, which it calls connectors, in public preview across all Copilot plans with 26 services at launch including Slack, Figma, Notion, Sentry and Linear, and introduced shared Copilot Automations that belong to a repository rather than one person. OpenCode 2.2.1, published 29 Oct, added a `/goal <objective>` command that keeps a session working until a reviewer agrees.

Top 3 things people are arguing about top-3-things-people-are-arguing-about 1. Is Claude Code’s status line worth its tokens? A gist Flamerix AI published on 26 Oct says background agents send their whole transcript to the model about every 30 seconds to write a 3 to 5 word status, and that in its own measurement this was 16.4% of Claude Code’s estimated spend. It offers a preload script to turn it off. An open issue on the Claude Code repo, filed 15 Aug, asks for a supported switch. More than 180 points on Hacker News on 29 Oct.
