Agent Plugins 1.0, an open standard for packaging agent skills and MCP servers into a single installable, vendor-independent plugin, is now generally available in VS Code, Copilot CLI, the Copilot SDK and the Copilot app. GitHub published the spec on August 6 with AWS, Anysphere, Microsoft, OpenAI and Vercel; Google joined as a core maintainer the same day.
why it mattersA shared plugin format means a skill-plus-MCP-server bundle can now ship once instead of needing a separate manifest and layout for every agent client.
GitHub Changelog
The August VS Code release lets a Claude-powered agent session switch between a Copilot subscription and a direct Anthropic API key between turns without reconfiguring the agent host, adds chat sticky scroll to keep long conversations anchored, and reloads local HTML previews automatically on save.
why it mattersRemoves a rigid lock-in point for teams mixing Copilot seats with direct Anthropic billing on the same editor.
Visual Studio Code
Copilot for JetBrains IDEs now supports memory that persists across sessions and bring-your-own-key access to local models via Ollama, alongside new server-based admin controls and reliability fixes across terminals, agents and MCP.
why it mattersLocal-model support via Ollama gives JetBrains users an offline/BYO-compute path that VS Code's Copilot extension has lacked.
