15 Hidden Claude Code Features Every Developer Should Bookmark

1. Code on Your Phone

Claude Code offers a mobile app for iOS and Android, allowing you to write and edit code without a computer. Install the app, select the Code tab, and you can seamlessly switch sessions between phone, web, desktop, or terminal. Use claude --teleport or /teleport to bring a cloud session back locally, and /remote-control to control a local session from your phone or browser. Boris Cherny notes that the remote‑control feature is enabled by default, and the /voice command provides hands‑free voice input.

2. Turn Claude into a 24/7 Employee

The /loop and /schedule commands let Claude run automatically at set intervals for up to a week. Boris shared his own loop configurations: /loop 5m /babysit – automatically reviews code, rebases, and pushes PRs to production. /loop 30m /slack-feedback – converts Slack feedback into PRs every 30 minutes. /loop /post-merge-sweeper – clears missed review comments. /loop 1h /pr-pruner – closes stale, unused PRs.

These loops act like four tireless interns, and Boris encourages experimenting with turning workflows into reusable skills and loops.

3. Give Claude Vision

Claude’s Chrome extension equips the AI with visual capabilities: it can take screenshots, manipulate the DOM, and verify styles. The desktop version also includes automatic web‑server startup and testing. By allowing Claude to see its own output, it can iterate toward better results.

4. Worktree: The Key to Parallel Universes

Claude Code natively supports Git worktrees, enabling dozens of Claude instances to run concurrently without interference. Use claude -w to start a session in a new worktree. The /batch command first gathers task requirements, then distributes them across hundreds or thousands of agents in separate worktrees. For example, migrating 1,000 JavaScript files to TypeScript can be parallelized by launching 100 agents, each handling ten files.

5. Small Details with Big Impact

/btw

– ask a side question while an agent is running a task without opening a new window. /branch and --fork-session – fork the current session into a new branch for exploration. --bare – speeds up SDK startup tenfold by skipping local config searches (currently a design quirk). --add-dir – add access to additional repositories when launching Claude. --agent – define custom agents with system prompts and toolsets in .claude/agents and invoke them via claude --agent=YourName.

Boris provided a link to his original fifteen‑tweet thread for readers to try each tip. Using Claude merely as a terminal tool wastes its potential; applying these hidden tricks can turn you into a productivity powerhouse.
