Migrate Cursor Rules to Skills, Subagents, and Plugins (Cursor 3.11)
Cursor did not delete rules. It split them. This checklist sorts a .cursorrules file and a folder of .mdc rules into the four things they should be in Cursor 3.11: an AGENTS.md, a small set of surviving rules, skills, and subagents, then bundles the result as a plugin.
Copilot MCP Allowlists Land in Enterprise Managed Settings
GitHub's August 6, 2026 changelog adds allowedMcpServers and deniedMcpServers to copilot/managed-settings.json. URL and argv matchers, deny-wins precedence, and a fail-closed default the older name-based registry never had.
Migrate a Custom TypeScript Agent Loop to the Cursor SDK (@cursor/sdk 1.0.26)
A step-by-step checklist for retiring a hand-rolled while-loop agent and running the same job on @cursor/sdk 1.0.26. The tool bodies survive, the loop does not, and three things you probably rely on have no equivalent: a system prompt string, a tool allowlist, and per-turn control.
Migrate a Custom Multi-Agent Orchestrator to Handoff Orchestration in Agent Framework 1.17
Replace a hand-rolled classifier-plus-switch router with AgentWorkflowBuilder.CreateHandoffBuilderWith in Microsoft.Agents.AI.Workflows 1.17.0. What breaks, the six migration steps, and the gotchas around agent Ids, descriptions, and context broadcast.
Copilot Automations Now Trigger on Issue and PR Comments
GitHub's August 3, 2026 changelog adds a comment trigger to Copilot cloud agent automations, replacing the issue_comment workflow plus PAT plus REST dispatch that teams have been hand-rolling since June.
Subtask vs Fork vs Background Agent in Claude Code: Which Delegation to Reach For
A named subagent starts cold, a fork inherits your whole conversation and shares your prompt cache, and a background agent is a second Claude Code session entirely. The trap is the naming: /fork stopped being the in-session fork at v2.1.212 and /subtask took over.
Declarative YAML Workflows vs Code-First Orchestration in Microsoft Agent Framework
Use declarative YAML when the graph is a sequential routing decision that non-developers change often. Use code-first WorkflowBuilder the moment you need parallelism, custom executors, or a non-Foundry agent. Here is the decision, the action catalog limits, and the code both ways.
Auto Mode vs Manual Approval in Claude Code: What Each Mode Actually Allows Through
Manual gates every tool call on you. Auto mode gates them on a classifier with 32 built-in block rules. The mode that surprises people is neither: acceptEdits auto-approves rm, mv, and sed, not just file edits. Measured on Claude Code 2.1.123.
Agent Framework's Copilot Provider Turns the Copilot CLI Into a Plain AIAgent
Microsoft.Agents.AI.GitHub.Copilot 1.16.0 shipped on July 30, 2026. The Copilot CLI runtime now sits behind the ordinary AIAgent abstraction, permissions are deny-by-default, and Squad plugs a whole agent team in as one AIAgent.
