Spin up 3–5 git worktrees at once, each running its own Claude session in parallel. It's the single biggest productivity unlock, and the top tip from the team. Personally, Boris uses multiple git checkouts, but most of the Claude Code team prefers worktrees — it's the reason @amorisscode built native support for them into the Claude Desktop app!
Some people also name their worktrees and set up shell aliases (2a, 2b, 2c) so they can hop between them in one keystroke. Others have a dedicated "analysis" worktree that's only for reading logs and running BigQuery.
