☕️ VS Code adds side-by-side AI chats

• VS Code 1.134 now lets you arrange multiple chats in a session into horizontal or vertical grid groups, dragging conversations or subagent chats side by side to compare results and monitor agent work simultaneously.
• A new prompt timeline in the Agents window transcript gutter marks each prompt as a dot, shows lines added and removed when a prompt changes files, and links directly to those changes for review.
• Ctrl+F now searches across Chat view, chat editors, and the Agents window, including off-screen content, with case matching, whole-word, and regex options, while HTML files can be set to open in the integrated browser for preview by default.

• Mojo, the systems language from Modular, has shipped its compiler and toolchain under an Apache 2 license, following its 1.0 release last week and fulfilling an open-source promise made back in May 2023.
• Rather than becoming a Python superset as first pitched, Mojo pivoted in August 2025 to being its own language with Python-inspired syntax, optimized to make GPU programming less painful even without full compatibility with existing code.
• Modular now leans on AI-assisted coding tools to migrate Python to Mojo, betting that maturing tooling and ecosystem support will smooth the transition instead of relying on drop-in interoperability with the current Python codebase.

• TrueFoundry has released TrueForge, an open source agent harness pitched as an alternative to Anthropic's Claude Managed Agents, letting engineers build, deploy, debug, and govern production AI agents on any model or MCP server at roughly half the operating cost.
• TrueForge ships with support for OpenAI, Anthropic, and 20+ other models, plus 40+ built-in tools, sandboxed execution, human-approval workflows, large-context handling, generative UI, and Tavily-powered web search, routing every model call and MCP interaction through TrueFoundry's AI Gateway for budget and guardrail enforcement.
• Teams run it on their own infrastructure with their own keys, routing each task by cost, latency, or quality; on 14 level-one and level-two tasks from DevRev's Enterprise-Bench, TrueForge came in 50% cheaper at similar accuracy by using fewer tokens and non-Anthropic models.

• Harness launched a set of AI agents that scan for software vulnerabilities, judge which are exploitable, and draft validated fixes, opening a pull request against the flawed function for developers to approve before anything ships.
• The pipeline runs a deterministic static scanner, then an AI layer that trims false positives and catches logic flaws like missing authorization checks, while a Zero-Day Agent flags newly disclosed bugs and virtual patching blocks exploitation in production without code changes.
• Harness said frontier models surface roughly 10 times more vulnerabilities than conventional scanners, and the agents share one set of reachability data to keep teams off unexploitable findings, aiming to shrink discovery-to-fix time from weeks to hours.

• Microsoft is embedding agentic AI into Azure Cosmos DB, letting AI tools inspect database structure, generate queries against real schemas, and execute them with developer approval directly inside the workflow.
• GitHub Copilot in VS Code can now sample documents from a container to learn its schema before writing queries and dropping them into the Cosmos DB Query Editor, though sampling consumes request units and needs consent.
• The Cosmos DB Agent Kit ships 100+ recommendations on data modeling, partition keys, indexing, and vector search across Copilot, Claude Code, Codex, Cursor, and Gemini CLI, plus an optional local MCP server via Cosmos DB Shell.

• Microsoft has shipped Aspire 13.5, refreshing the dashboard's visual design and homepage while expanding how AppHosts interact with developers and adding more flexibility to how applications get deployed to Kubernetes and Azure.
• The Interaction Service now supports JSON and YAML file imports via a file picker, progress dialogs with cancellation, and named arguments, while WithTerminal() adds an experimental interactive terminal for shells and REPLs inside the dashboard.
• TypeScript AppHosts are now generally available with feature parity to C#, and breaking changes include renaming ServiceProvider to Services, deprecating the GitHub Models integration, and removing the dashboard's AI Assistant chat.
