🍻 The Agent Joined the Group Chat

GitHub moved Copilot cloud-agent work into Slack and Microsoft Teams, where the whole crew can see the plan, steer the job, and stop a bad turn. Figma brought the counterweight: direct vector edits, a detachable agent window, and spacing that hands off more cleanly to CSS. Big glass-half-full energy—with one house rule. Name the reviewer, show the permissions, and keep the craft visible.

GitHub’s Slack preview can start a Copilot agent session from a message, channel, or thread. With permitted context, it can investigate, change code, validate in a cloud sandbox, and open a pull request. The feast is visibility: teammates can inspect the plan and diffs, redirect the work, or stop it. Existing permissions still apply, and admins can require extra merge approval. Multiplayer agents, brakes attached. Beautiful.

Microsoft Teams gets the same multiplayer treatment. Anyone can add context and steer; only participants with repository write access can trigger changes. The session cooks asynchronously in a cloud sandbox, then moves to the terminal, Copilot app, or an integrated development environment for review. Paid plans, AI credits, and separate sandbox charges apply. Name the human reviewer before the meeting ends and the handoff leaves with a pulse.

Figma can now park agent chat in a movable window while the designer works. Figma Draw added direct vector erasing and drag-to-fill recoloring; auto layout gained spacing that mirrors CSS Between, Around, and Evenly. Enterprise-managed Model Context Protocol authorization also reached general availability for Enterprise and Organization plans. The machine gets a better seat; the designer keeps the pencil. Raise a glass to that.

From August 28: o3 in ChatGPT passed its date, the official DALL·E GPT has two calendar days left, and six listed GitHub Copilot models have four. Inventory saved images, pinned models, prompts, policies, and integrations—in that order.

Give one low-risk backlog question the shared-room treatment. Keep the first pass investigation-only. The prize is fewer invisible assumptions at review time.

• Post the result, repository, evidence, two non-goals, and review owner. Ask for a plan only—no edits, messages, merges, or external actions.
• Have one teammate add context and another redirect. Record the permission, cost, or scope assumption this exposes.
• Keep it only if a reviewer can trace the decision, evidence, and owner without a private side conversation.

No funeral procession—just a crisp Friday inventory before the doors close.

• Codex MCP command · Deprecated August 24. Move integrations to the app server or Codex plugin; OpenAI gives no removal date.
• OpenAI o3 in ChatGPT · Retired August 26. The API is unchanged; test pinned ChatGPT workflows.
• Official DALL·E GPT · Retires August 30. Download keepers and move active work to ChatGPT Images; user-created image GPTs are unaffected.
• Six GitHub Copilot models · Retire September 1. Check pinned models and policy access, then test the replacement; GitHub notes a Claude Sonnet 4.6 annual-plan exception.

Receipts: Locked factual blocks link to official sources. The August 21–27 grid groups related changes as editorial signals, not total market activity. Calendar days use August 28 as day zero. The o3, DALL·E GPT, and GitHub notices were published before their operational dates; the chart does not imply replacement parity, availability, rollout timing, quality, cost, or impact.
