Claude Code, Cursor, and the GitHub Copilot coding agent all ship host allowlists for outbound traffic, and all three default to something looser than you want. The exact settings keys, a policy you can copy, and the four surfaces the allowlist does not cover.

Microsoft Agent Framework shipped Declarative Workflows 1.0 on July 23, 2026. Python's agent-framework-declarative 1.0.0 reaches parity with the .NET Microsoft.Agents.AI.Workflows.Declarative package, so multi-agent routing lives in YAML instead of C#.

The legacy HTTP+SSE transport used two endpoints and a sticky connection. Streamable HTTP uses one. Here is the step-by-step migration for the TypeScript and Python SDKs, the client configs you have to repoint, and the proxy buffering gotcha that makes the new endpoint look broken.

How to convert .github/prompts/*.prompt.md into .github/skills/<name>/SKILL.md so GitHub Copilot loads them automatically. What breaks, what maps 1:1, and how to verify each skill fires.

Version 2.1.218 moves /code-review off your main conversation into a background subagent, and fork-context skills now background by default. Here is what changed and how to opt out.

Pick Copilot coding agent when the work starts and ends on GitHub and you want issue-to-PR with native branch protection. Pick Cursor cloud agents when you want a live, editor-attached VM, multi-repo tasks, and to take over the run by hand. Full feature matrix, the 59-minute cap, the Actions-approval gotcha, and June 2026 billing for both.

Version 2.1.213 caps concurrent subagents and stops nested spawns by default, building on the per-session limits from 2.1.212. Here are the new defaults and env vars.

Claude Code compacts, then a single oversized file read or tool result immediately refills the window and it compacts again. Drop the item with /clear, read files in slices, and force big output to disk.

Sequential for pipelines, concurrent for fan-out, group chat for moderated rounds, handoff for routing, magentic for open-ended planning. The C# builders and how to choose.

An MCP server on Node 16 warns EBADENGINE at install, then dies with 'fetch is not defined' on the first tool call. Upgrade to Node 18+ (20+ for the 2.x SDK) or polyfill the web globals.
