Both let one agent spawn isolated workers from a Markdown file, but Claude Code nests five levels deep with per-agent tool allowlists and worktree isolation, while Cursor keeps it to two levels with a single readonly switch and reads Claude's format for free. Pick by where your agents run, not by brand.

Build a skill to change how Claude works, a subagent to protect your context window, and an MCP server to reach a system Claude cannot otherwise touch. They solve three different problems, not one. Here is the decision, the mechanics, and the config for each.

Claude Code v2.1.200 (July 3, 2026) renames the 'default' permission mode to 'Manual' across the CLI, VS Code, and JetBrains, and stops AskUserQuestion dialogs from auto-continuing. The config value stays 'default', with 'manual' accepted as an alias.

Use stdio for a local server one client launches, use Streamable HTTP for anything remote or multi-client, and do not build new HTTP+SSE servers -- that transport was deprecated in the 2025-03-26 MCP spec. Here is the decision, the wire-level differences, and the code for each.

High memory usage and context overflow are two different problems in Claude Code. Raise the Node heap for RAM, use /context and /compact for the window, /heapdump to diagnose.

After auto-compaction, Claude Code can leave your MCP server connected but with no tools. Run /mcp to reconnect; if tools stay gone, /clear or restart. Here is why and how to prevent it.

Claude Code v2.1.191 (June 24, 2026) extends /rewind so you can restore conversation and code state from before you ran /clear, recovering context that used to be gone for good.

MCP error -32000 means your MCP server process exited before the handshake finished. Fix the missing binary, the Windows cmd /c wrap, the event-loop exit, and the startup race.

The new sandbox.credentials setting in Claude Code v2.1.187 denies reads of credential files and unsets secret env vars before sandboxed Bash commands run. Here is why the default read policy was a hole, and how to close it.

Claude Code v2.1.183 (June 19, 2026) blocks git reset --hard, git clean -fd, and terraform/pulumi/cdk destroy in auto mode unless you asked for them, closing the agentic loophole where one bad turn nukes uncommitted work.
