+# 15 Hidden & Under-Utilized Features in Claude Code — From Boris Cherny
+
+A summary of tips shared by Boris Cherny ([@bcherny](https://x.com/bcherny)), creator of Claude Code, on March 30, 2026.
+
+<table width="100%">
+<tr>
+<td><a href="../">← Back to Claude Code Best Practice</a></td>
+<td align="right"><img src="../!/claude-jumping.svg" alt="Claude" width="60" /></td>
+</tr>
+</table>
+
+---
+
+## Context
+
+Boris shared a bunch of his favorite hidden and under-utilized features in Claude Code, focusing on the ones he uses the most.
+
+<a href="https://x.com/bcherny/status/2038454336355999749"><img src="assets/boris-30-mar-26/0.png" alt="Boris Cherny intro tweet" width="50%" /></a>
+
+---
+
+## 1/ Claude Code Has a Mobile App
+
+Did you know Claude Code has a mobile app? Boris writes a lot of his code from the iOS app — it's a convenient way to make changes without opening a laptop.
+
+- Download the Claude app for iOS/Android
+- Navigate to the **Code** tab on the left
+- You can review changes, approve PRs, and write code directly from your phone
+
+<a href="https://x.com/bcherny/status/2038454337811386436"><img src="assets/boris-30-mar-26/1.png" alt="Claude Code mobile app" width="50%" /></a>
+
+---
+
+## 2/ Move Sessions Between Mobile/Web/Desktop and Terminal
+
+Run `claude --teleport` or `/teleport` to continue a cloud session on your machine. Or run `/remote-control` to control a locally running session from your phone/web.
+
+- **Teleport**: pulls a cloud session down to your local terminal
+- **Remote Control**: lets you control a local session from any device
+- Boris has **"Enable Remote Control for all sessions"** set in his `/config`
+
+<a href="https://x.com/bcherny/status/2038454339933548804"><img src="assets/boris-30-mar-26/2.png" alt="Teleport and Remote Control" width="50%" /></a>
+
+---
+
+## 3/ /loop and /schedule — Two of the Most Powerful Features
+
+Use these to schedule Claude to run automatically at a set interval, for up to a week at a time. Boris has a bunch of loops running locally:
+
+- `/loop 5m /babysit` — auto-address code review, auto-rebase, and shepherd PRs to production
+- `/loop 30m /slack-feedback` — automatically put up PRs for Slack feedback every 30 mins
+- `/loop /post-merge-sweeper` — put up PRs to address code review comments he missed
+- `/loop 1h /pr-pruner` — close out stale and no longer necessary PRs
+- ...and lots more!
+
+Experiment with turning workflows into skills + loops. It's powerful.
+
+<a href="https://x.com/bcherny/status/2038454341884154269"><img src="assets/boris-30-mar-26/3.png" alt="/loop and /schedule" width="50%" /></a>
+
+---
+
+## 4/ Use Hooks to Deterministically Run Logic
+
+Use hooks to run logic as part of the agent lifecycle. For example:
+
+- **Dynamically load** in context each time you start Claude (`SessionStart`)
+- **Log every bash command** the model runs (`PreToolUse`)
+- **Route permission prompts** to WhatsApp for you to approve/deny (`PermissionRequest`)
+- **Poke Claude** to keep going whenever it stops (`Stop`)
+
+<a href="https://x.com/bcherny/status/2038454343519932844"><img src="assets/boris-30-mar-26/4.png" alt="Use hooks" width="50%" /></a>
+
+---
+
+## 5/ Cowork Dispatch
+
+Boris uses Dispatch every day to catch up on Slack and emails, manage files, and do things on his laptop when he's not at a computer. When he's not coding, he's dispatching.
+
+- Dispatch is a **secure remote control** for the Claude Desktop app
+- It can use your MCPs, browser, and computer, with your permission
+- Think of it as a way to delegate non-coding tasks to Claude from anywhere
+
+<a href="https://x.com/bcherny/status/2038454345419936040"><img src="assets/boris-30-mar-26/5.png" alt="Cowork Dispatch" width="50%" /></a>
+
+---
+
+## 6/ Use the Chrome Extension for Frontend Work
+
+The most important tip for using Claude Code: **give Claude a way to verify its output.** Once you do that, Claude will iterate until the result is great.
+
+- Think of it like asking someone to build a website but they aren't allowed to use a browser — the result probably won't look good
+- Give Claude a browser and it will write code and iterate until it looks good
+- Boris uses the Chrome extension every time he works on web code — it tends to work more reliably than other similar MCPs
+
+<a href="https://x.com/bcherny/status/2038454347156398333"><img src="assets/boris-30-mar-26/6.png" alt="Chrome extension for frontend" width="50%" /></a>
+
+---
+
+## 7/ Use the Claude Desktop App to Auto-Start and Test Web Servers
+
+Along the same vein, the Desktop app bundles in the ability for Claude to **automatically run your web server and even test it in a built-in browser.**
+
+- You can set up something similar in CLI or VSCode using the Chrome extension
+- Or just use the Desktop app for the integrated experience
+
+<a href="https://x.com/bcherny/status/2038454348804714642"><img src="assets/boris-30-mar-26/7.png" alt="Desktop app web server testing" width="50%" /></a>
+
+---
+
+## 8/ Fork Your Session
+
+People often ask how to fork an existing session. Two ways:
+
+1. Run `/branch` from your session
+2. From the CLI, run `claude --resume <session-id> --fork-session`
+
+`/branch` creates a branched conversation — you are now in the branch. To resume the original, use `claude -r <original-session-id>`.
+
+<a href="https://x.com/bcherny/status/2038454350214041740"><img src="assets/boris-30-mar-26/8.png" alt="Fork your session" width="50%" /></a>
+
+---
+
+## 9/ Use /btw for Side Queries
+
+Boris uses this all the time to answer quick questions while the agent works. `/btw` lets you ask a side question without interrupting the agent's current task.
+
+Example:
+```
+/btw how do I spell dachshund?
+> dachshund — German for "badger dog" (dachs + badger, hund + dog).
+↑/↓ to scroll · Space, Enter, or Escape to dismiss
+```
+
+<a href="https://x.com/bcherny/status/2038454351849787485"><img src="assets/boris-30-mar-26/9.png" alt="/btw for side queries" width="50%" /></a>
+
+---
+
+## 10/ Use Git Worktrees
+
+Claude Code ships with deep support for git worktrees. Worktrees are essential for doing lots of parallel work in the same repository. Boris has **dozens of Claudes running at all times**, and this is how he does it.
+
+- Use `claude -w` to start a new session in a worktree
+- Or hit the **"worktree" checkbox** in the Claude Desktop app
+- For non-git VCS users, use the `WorktreeCreate` hook to add your own logic for worktree creation
+
+<a href="https://x.com/bcherny/status/2038454353787519164"><img src="assets/boris-30-mar-26/10.png" alt="Git worktrees" width="50%" /></a>
+
+---
+
+## 11/ Use /batch to Fan Out Massive Changesets
+
+`/batch` interviews you, then has Claude fan out the work to as many **worktree agents** as it takes (dozens, hundreds, even thousands) to get it done.
+
+- Use it for large code migrations and other kinds of parallelizable work
+- Each worktree agent works independently on its own copy of the codebase
+
+<a href="https://x.com/bcherny/status/2038454355469484142"><img src="assets/boris-30-mar-26/11.png" alt="/batch for massive changesets" width="50%" /></a>
+
+---
+
+## 12/ Use --bare to Speed Up SDK Startup by Up to 10x
+
+By default, when you run `claude -p` (or the TypeScript or Python SDKs), Claude searches for local CLAUDE.md's, settings, and MCPs. But for non-interactive usage, most of the time you want to explicitly specify what to load via `--system-prompt`, `--mcp-config`, `--settings`, etc.
+
+- This was a design oversight when the SDK was first built
+- In a future version, they will flip the default to `--bare`
+- For now, opt in with the flag to get up to **10x faster startup**
+
+```bash
+claude -p "summarize this codebase" \
+    --output-format=stream-json \
+    --verbose \
+    --bare
+```
+
+<a href="https://x.com/bcherny/status/2038454357088457168"><img src="assets/boris-30-mar-26/12.png" alt="--bare flag for SDK startup" width="50%" /></a>
+
+---
+
+## 13/ Use --add-dir to Give Claude Access to More Folders
+
+When working across multiple repositories, Boris usually starts Claude in one repo and uses `--add-dir` (or `/add-dir`) to let Claude see the other repo.
+
+- This not only tells Claude about the repo, but also **gives it permissions** to work in the repo
+- Or, add `"additionalDirectories"` to your team's `settings.json` to always load in additional folders when starting Claude Code
+
+<a href="https://x.com/bcherny/status/2038454359047156203"><img src="assets/boris-30-mar-26/13.png" alt="--add-dir for multiple repos" width="50%" /></a>
+
+---
+
+## 14/ Use --agent to Give Claude Code a Custom System Prompt & Tools
+
+Custom agents are a powerful primitive that often gets overlooked. To use it, just define a new agent in `.claude/agents/`, then run:
+
+```bash
+claude --agent=<your agent's name>
+```
+
+- Agents can have restricted tools, custom descriptions, and specific models
+- They're great for creating read-only agents, specialized review agents, or domain-specific tools
+
+<a href="https://x.com/bcherny/status/2038454360418787764"><img src="assets/boris-30-mar-26/14.png" alt="--agent for custom system prompts" width="50%" /></a>
+
+---
+
+## 15/ Use /voice to Enable Voice Input
+
+Fun fact: Boris does most of his coding by speaking to Claude, rather than typing.
+
+- Run `/voice` in CLI then hold the space bar to speak
+- Press the voice button on Desktop
+- Or enable dictation in your iOS settings
+
+<a href="https://x.com/bcherny/status/2038454362226467112"><img src="assets/boris-30-mar-26/15.png" alt="/voice for voice input" width="50%" /></a>
