Claude Code's creator just leaked 15 hidden features engineers are missing: Full list in the comments! P.S. I share 1 practical AI Coding Tip everyday with 200K+ engineers here: codenewsletter.ai/subscribe?ut...…

1) Code from your phone Claude Code has a mobile app, and Boris uses it a lot. You can make real code changes directly from iOS/Android. 2) Move sessions across devices • 𝗰𝗹𝗮𝘂𝗱𝗲 --𝘁𝗲𝗹𝗲𝗽𝗼𝗿𝘁 → move a cloud session to your machine • /𝗿𝗲𝗺𝗼𝘁𝗲-𝗰𝗼𝗻𝘁𝗿𝗼𝗹 → control a local session from your phone or web Boris enables remote control for all sessions by default. 3) Automate work with /𝗹𝗼𝗼𝗽 and /𝘀𝗰𝗵𝗲𝗱𝘂𝗹𝗲 • /𝗹𝗼𝗼𝗽 𝟱𝗺 /𝗯𝗮𝗯𝘆𝘀𝗶𝘁 → auto handle code review, rebase, and push PRs forward • /𝗹𝗼𝗼𝗽 𝟯𝟬𝗺 /𝘀𝗹𝗮𝗰𝗸-𝗳𝗲𝗲𝗱𝗯𝗮𝗰𝗸 → post PRs for feedback every 30 min • /𝗹𝗼𝗼𝗽 𝟭𝗵 /𝗽𝗿-𝗽𝗿𝘂𝗻𝗲𝗿 → clean up stale PRs Anything repetitive can be turned into an automated workflow. 4) Hooks to control the agent lifecycle Run logic at specific moments: • SessionStart → load context automatically • PreToolUse → log every bash command • PermissionRequest → route approvals (e.g. to WhatsApp) • Stop → prompt Claude to continue 5) Cowork Dispatch = remote control for your computer Used it daily to: • Read Slack and email • Manage files • Perform actions on the laptop 6) Give Claude a way to verify its output If Claude can’t see the result, it can’t improve it. Boris uses the Chrome extension so Claude can test and iterate. 7) Desktop app to run and test apps Claude Desktop can: • Start your web server • Open and test it in a built-in browser 8) Fork sessions instead of restarting → /𝗯𝗿𝗮𝗻𝗰𝗵 from inside the session → 𝗰𝗹𝗮𝘂𝗱𝗲 --𝗿𝗲𝘀𝘂𝗺𝗲 <𝗶𝗱> --𝗳𝗼𝗿𝗸-𝘀𝗲𝘀𝘀𝗶𝗼𝗻 from CLI Explore ideas without losing context. 9) Use /𝗯𝘁𝘄 for side questions Ask quick questions without interrupting the main task. 10) Parallel work with git worktrees Claude Code has deep support for worktrees. Boris runs many sessions in parallel, each in its own worktree. 11) Use /𝗯𝗮𝘁𝗰𝗵 for large-scale changes /𝗯𝗮𝘁𝗰𝗵 breaks a task into many smaller ones and distributes them across multiple agents (even hundreds). 12) Speed up SDK usage with --𝗯𝗮𝗿𝗲 By default, Claude loads configs, MCPs, and 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱 files. With --𝗯𝗮𝗿𝗲, you skip that and explicitly define what to load → up to 10x faster startup. 13) Work across multiple repos Start Claude in one repo, add access to another with --𝗮𝗱𝗱-𝗱𝗶𝗿. Or set 𝗮𝗱𝗱𝗶𝘁𝗶𝗼𝗻𝗮𝗹𝗗𝗶𝗿𝗲𝗰𝘁𝗼𝗿𝗶𝗲𝘀 in your team's 𝘀𝗲𝘁𝘁𝗶𝗻𝗴𝘀.𝗷𝘀𝗼𝗻. 14) Create custom agents with --𝗮𝗴𝗲𝗻𝘁 Define agents in .𝗰𝗹𝗮𝘂𝗱𝗲/𝗮𝗴𝗲𝗻𝘁𝘀 with custom prompts and tools, then run: 𝗰𝗹𝗮𝘂𝗱𝗲 --𝗮𝗴𝗲𝗻𝘁=<𝗻𝗮𝗺𝗲> This is a powerful but often overlooked feature. 15) Use voice input Run /𝘃𝗼𝗶𝗰𝗲 (or use Desktop/iOS dictation) and speak instead of typing.
