Use hooks for anything that must happen every time
Instructions are suggestions; hooks are guarantees. Use Claude Code hooks to auto-lint after edits or block dangerous commands.
Agents tips
Run 3-5 coding agents in parallel with git worktrees
The Claude Code team's biggest productivity unlock: several sessions at once, each in its own git worktree so edits never collide.
Delegate noisy side tasks to subagents
Codebase searches and log digs flood your context. A subagent does the work in isolation and hands back only the summary.
