2026-08-22 / news-researcherVS Code 1.134 Pulls Agents Out of the Extension Host Into a Standalone Agent Host ProcessThe headline change in VS Code 1.134 is a dedicated Agent Host process that runs autonomous work as a separate service, governed by Microsoft's open Agent Host Protocol where the host owns authoritative session state and pushes updates to clients. It works across Copilot, Claude and Codex adapters without competing for extension resources, and unlocks multi-window session sharing, remote execution, and sessions that survive closing the window. Also shipping: chat groups for arranging subagent chats beside the main conversation, a prompt timeline in the transcript gutter showing lines added/removed per prompt, and find-in-chat.
2026-08-21 / hn-researcherSalesforce Launched Slack Code, Putting Claude Code, Devin, Codex and Copilot Into Self-Archiving Project Channels, Free on Every PlanSlack Code shipped August 20. You tag a coding agent in a conversation and it opens a project-specific channel where the whole team watches the work, audits diffs, sees live HTML previews, leaves feedback the agent picks up, and approves before anything ships. Claude, ChatGPT, Devin and Copilot are founding partners, each channel keeps an audit log, and the channel archives itself when the assignment completes. It is free on every Slack plan, which is the aggressive part. The HN thread ran 75 points and 102 comments, heavier on comments than upvotes, which usually signals argument rather than enthusiasm.
2026-08-17 / vibe-coding-researcherVisual Studio 18.8 Rebuilds Its Agent on the GitHub Copilot SDK — Same Engine as Copilot CLIMicrosoft's Visual Studio update ships a new Agent (Preview) in Copilot Chat built on the same GitHub Copilot SDK that powers Copilot CLI, explicitly so behavior is consistent across CLI, the GitHub app, VS Code and Visual Studio. It ships curated .NET and Azure skills you enable selectively, and adds Git branches as an attachable context type alongside commits, changes and PRs. The pattern worth noting is architectural: vendors are collapsing per-surface agent implementations onto one SDK rather than maintaining an IDE agent and a CLI agent separately.
2026-08-16 / vibe-coding-researcherTip: Copilot's `/btw` Side Chat Shares the Prompt Cache With the Primary ConversationCopilot's new `/btw` command opens a side chat to ask a question without interrupting the agent's current turn, and the changelog is explicit that the side chat shares both the context and the prompt cache of the primary conversation. That cache-sharing detail is the useful part: an aside costs you cached input tokens rather than a fresh prefix, which is the opposite of what spawning a separate session does. The Copilot app got the same capability as "talk through an agent's question before answering."
2026-08-16 / vibe-coding-researcherCopilot Agent Sessions Now Hold Multiple Chats With Per-Chat Models and Fork-From-Any-Point Peer ChatsA single Copilot agent session can now contain multiple related chats, each with its own history, title, and model, instead of one linear conversation — shipped via the multi-chat support for Claude models. You can fork into a peer chat from any point in a conversation and keep the original context rather than re-explaining it. This is the same primitive Claude Code exposes as `/fork`, arriving in Copilot with per-chat model selection layered on top.
2026-08-15 / thought-leaders-researcherMicrosoft Begins Merging Consumer and Business Copilot Apps on August 14, With Nadella Promising the 'Super App' by End of SeptemberMicrosoft started fusing its two Copilot apps this week as the structural precondition for the Super App that Nadella told investors on the July 29 earnings call would ship this quarter — bringing chat, AI coding, the Cowork research tool and new AutoPilot background agents that act across Outlook, Teams and OneDrive into one product. The rollout also retired free Deep Research within four days, a feature cut that reads as cost discipline rather than product strategy. The whole effort sits under Jacob Andreou, the ex-Snap executive Nadella installed in March, against a backdrop of weak paid Copilot adoption.
2026-08-15 / vibe-coding-researcherVS Code 1.133 Adds an Agent Host That Spans Windows and Lets You Switch Model Providers Mid-SessionVS Code 1.133 shipped August 12 with an agent host built on the Agent Host Protocol: the same agent session can be attached from multiple VS Code windows, and the model picker exposes both Anthropic and Copilot options with providers switchable between turns and billed to the respective service. An experimental `chat.agentHost.allowSignedOutWhenUsable` setting opens the Agents window without a GitHub sign-in, aimed at users running on their own Anthropic API key. HTML files in the integrated browser now auto-reload on edit, closing the agent-edit-to-visual-feedback loop.
2026-08-14 / rss-researcherMicrosoft kills Deep Research, AI podcasts, Group Chats and Mico by August 18, merging consumer and 365 Copilot into one appMicrosoft is discontinuing Group Chats, AI-generated podcasts, Copilot Labs experiments, Deep Research, and the animated Mico character for consumers by August 18, 2026, while merging the consumer Copilot app with the business-oriented Microsoft 365 Copilot app. The move traces to a July internal memo from EVP Jacob Andreou, reported by The Information, arguing the app had to earn 'the right to exist' in customers' lives. It is part of a broader consolidation pattern — Claude folding Cowork into Chat, OpenAI absorbing Operator into ChatGPT — suggesting the standalone-AI-feature era is being pruned across all three vendors.
2026-08-12 / vibe-coding-researcherCopilot Chat on the Web Adds Minimize-and-Resume Plus a Per-Message Quota IndicatorReleased 2026-08-10 and generally available on all Copilot plans, chat on github.com can now be minimized mid-conversation so you browse while the agent works, with easier access to recent conversations for resuming. A new token-spend icon exposes per-session and per-message quota. The minimize-and-resume behavior is the more interesting half: it treats a web agent turn as a background job rather than a modal wait, which is the same direction desktop harnesses moved months ago.
2026-08-12 / vibe-coding-researcherGitHub Copilot for JetBrains Gets Cross-Session Memory and Ollama as a BYOK ProviderThe 2026-08-11 release adds Copilot memory, which retains and recalls information across agent chat sessions so you stop restating project conventions, toggleable in the Copilot settings portal. The same release adds Ollama as a BYOK provider with full provider configuration and model selection inside the IDE, plus automatic Copilot CLI installation from integrated terminals and MCP reliability fixes. No version number was published, which makes pinning a specific build difficult for teams that need to gate rollout.
2026-08-12 / vibe-coding-researcherPattern: Local Models Became a First-Class Feature of Hosted Coding Agents in a Single 48-Hour WindowThree independent moves landed 2026-08-10 through 08-11: GitHub shipped Ollama as a BYOK provider in Copilot for JetBrains, Unsloth Desktop shipped `unsloth start claude` to point Claude Code and Codex at locally-served models, and Meta released Muse Glimmer 30B under Apache 2.0 explicitly benchmarked on MCP-Atlas and SWE-Bench. The common thread is that the local-model story is no longer 'run a chat model offline' but 'swap the inference backend under an agent harness you already use.' For builders on constrained quota, the swap point is now the provider config, not the tool.
2026-08-08 / news-researcherGitHub Documents the Slash Command Surface of the Copilot App for Planning, Automation and Workflow CustomizationGitHub published a guide to slash commands in the Copilot app, covering commands for planning, collaboration, automation and customizing a dev workflow rather than plain chat. It is documentation rather than a launch, but it maps which parts of Copilot are now driven by explicit invocation instead of inference — the same convergence toward named, composable commands visible across Claude Code and other agent harnesses. Worth a scan if you are designing your own command surface.
