4 hacks
Add the words "use a workflow" to a prompt and Claude writes a JavaScript orchestration script that runs subagents in the background, keeping only the final answer in your context.
Spin up a subagent for codebase search or verification so only the conclusion returns to your main context.
A skill that checks a link or reformats a file does not need your session model. Set model, effort and context: fork in the frontmatter so cheap skills stay cheap.
Define custom subagents with `isolation: worktree` so delegated edits happen on a temporary branch checkout.
