Ch06 Power Features

# Chapter 6 prompts — The Features Nobody Told You About

**Hour block: hours 21-28** of the book's 48-hour build.

> ⚠ **Every `claude …` command and every `/…` command on this page needs a PAID
> Claude Code subscription, and most of them open an interactive terminal UI or a
> paired mobile session.** This is the chapter of paid, interactive features —
> remote control, background agents, voice mode — and none of it is something a
> script or a CI job can drive. **This repository never runs a single one of these
> commands, and neither does its CI.** Everything this repository actually
> *executes* is offline and keyless. Treat everything below as documentation to
> read, not code to run unattended.

**The full pack, with every prompt transcribed verbatim: [`prompts/ch06-power-features.md`](../../prompts/ch06-power-features.md)**
The pack is the source of truth for exact command text; this page is the guide to
navigating it. The commands are reproduced character-for-character in both places —
if a screen looks different from what you read here, trust the session's own
prompts and `code.claude.com` over either document (ch06:33).

## What this chapter's prompts do

This chapter covers five features most Claude Code users never discover: remote
control (start a task at your desk, monitor and approve it from your phone),
background agents running in parallel git worktrees, voice mode, the language
server protocol (LSP) for instant code lookups instead of file-by-file scanning,
and MCP servers that give Claude access to things beyond your project files (a
filesystem, a browser). The chapter is explicit that the exact keystrokes and menu
text shift between Claude Code versions — it teaches the concepts and tells you to
confirm the current syntax against `claude --help` and the docs.

## When you use them

Hours 21-28, after the app works and looks reasonable. None of these features are
required to finish the Task Tracker — they're throughput multipliers for someone
who already has the Chapter 3-5 habits down. Before you start: a working local
project, a paid Claude Code session, and (for remote control) a phone with a
browser or the Claude app. The book's own adoption order (ch06:295-306) is LSP
first, then locking in Chapter 5's conversation and effort habits, then remote
control, then background agents, then voice mode, then MCP last.

## Index of every prompt/command in the pack

| # | Prompt / command | Cite | What it does |

| 3 | `/mobile` | ch06:28-31 | Prints a QR code to download the Claude mobile app |
| 4 | `/login` | ch06:28-41 | Signs the session in through your claude.ai login (remote control needs a paid plan login, not a raw API key) |
| 5 | Self-contained remote task | ch06:47-53 | A complete dashboard instruction with no back-and-forth needed, safe to run remotely |
| 6 | `/effort medium` | ch06:55-61 | Drops effort for a routine remote job |
| 7 | ⭐ The overnight job | ch06:65-71 | Runs the full test suite, generates coverage, and writes an `UNTESTED.md` — one self-contained instruction to leave running |
| 8 | `claude agents` | ch06:73-101 | Opens the agent view for starting and managing background sessions |
| 9 | `claude agents --help` | ch06:73-101 | Prints the agent view's own help text |
| 10 | `claude --worktree "search-feature"` | ch06:89-95 | Runs a background task in an isolated git worktree (short form `-w`) |
| 11 | `/voice` | ch06:116-174 | Turns on voice mode (push-to-talk) |
| 12 | Morning standup (voice) | ch06:140-174 | "Show me what files changed yesterday..." spoken instead of typed |
| 13 | Bug reporting (voice) | ch06:140-174 | Reports a badge-color bug by voice while clicking through the app |
| 14 | Talking through a feature (voice) | ch06:140-174 | Asks what a feature would take, explicitly without building it |
| 15 | End-of-session wrap-up (voice) | ch06:140-174 | Summarizes the day's changes and any TODOs, spoken |
| 16 | Confirm LSP is active | ch06:176-216 | Asks Claude whether the LSP is active and, if not, what to install |
| 17 | ⭐ LSP sanity check | ch06:176-216 | "Where is the `deleteTask` function defined?" — tests for an instant `file:line` answer with no file-scan |
| 18 | Add the filesystem MCP server | ch06:218-270 | `claude mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem <path>` |
| 19 | `claude mcp list` | ch06:218-270 | Lists registered MCP servers |
| 20 | `claude mcp get filesystem` | ch06:218-270 | Reports the directory the filesystem server is scoped to |
| 21 | Add the Playwright MCP server | ch06:218-270 | `claude mcp add playwright -- npx -y @playwright/mcp@latest` — automates the Chapter 4 screenshot loop |
| 22 | `claude mcp remove <name>` | ch06:218-270 | Removes a registered MCP server |
| 23 | `claude mcp add --help` | ch06:218-270 | Prints the `mcp add` command's own help text |

23 prompts/commands.
