Agent Plugins 1.0.0 standardizes exactly two component types: skills and MCP servers. Slash commands, hooks, subagents, rules, LSP servers, permission config and secrets all stay vendor-specific. Here is the field-by-field matrix across Claude Code, Cursor, Copilot and Codex, and which layout to author in.

A server that vanished from /mcp with no error is almost always an allowlist. Run claude mcp add on the same server: the add path prints the reason the load path swallows.

Cursor shipped Builds for Cloud Agents on August 13, 2026: a bootable filesystem snapshot of an already prepared machine. Cursor reports 3x faster time to first token. The lever you control is the install vs start split in .cursor/environment.json.

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.

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.

Cursor Router shipped on July 22, 2026. Auto now classifies every request and routes it to a different model, and the Cost, Balance, and Intelligence modes change both the quality you get and how you are billed.

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.

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.

Commit .cursor/mcp.json for the IDE, register shared servers under Dashboard > Integrations & MCP for cloud agents, and keep secrets out of git with ${env:...}. The full two-surface setup for Cursor 3.11 (July 2026), including why the repo file alone does not reach cloud agents.

Use Cursor 3.8's /automate skill to spin up a cloud agent that fires on GitHub events. Covers the five GitHub triggers added June 18, 2026, tool config, repo scope, and the Max Mode billing gotcha.
