Boris Cherny's 42 Claude Code Tips Organized as Installable Skill: Git Worktrees as 'Single Biggest Productivity Unlock', 5-10 Parallel Sessions Standard

Medium·medium signal

Boris Cherny (Claude Code creator) shared 42 tips across five threads (Jan-Feb 2026), now compiled into an installable Claude Code skill. Key revelations: the team runs 5 terminal instances plus 5-10 claude.ai/code sessions simultaneously. Git worktrees (3-5 at once) are called 'the single biggest productivity unlock.' Most sessions start in Plan mode. Slash commands in .claude/commands/ eliminate repetitive prompting. The philosophy is 'surprisingly vanilla' — Claude Code works great out of the box. The tips form one cohesive workflow, not 42 separate tricks.
