7 Claude Code Features You're Not Using (But Should Be)
TL;DR
Voice input is a hidden speed multiplier — Claude Code’s built-in
/voicecommand works like WhisperFlow or SuperWhisper, letting you talk prompts instead of typing, which the creator says is roughly 3x faster.Launching Claude in the right folder prevents dumb mistakes — if you don’t
cdinto the project directory before opening Claude Code, it may miss files, get confused about context, and waste both time and tokens.Project-specific
CLAUDE.mdis one of the highest-leverage setup steps — the creator calls it possibly the most important tip, because it gives Claude persistent context about the project, structure, and working assumptions.A global

The Breakdown
The pitch: most Claude users are leaving a 10x productivity gain on the table
The video opens with a strong claim: most people could get an “instant 10x” from Claude Code just by using seven features they probably didn’t even know existed. The creator’s framing is simple: people open Claude, start typing, and never discover the deeper tools that actually change how you work.
/voice: built-in AI dictation that makes prompting much faster
The first feature is Claude Code’s voice mode, which the creator compares to tools like WhisperFlow and SuperWhisper. You trigger it with /voice, then hold the space bar to speak naturally; Claude formats the result with punctuation so prompts come through cleanly, and the creator points out that talking is typically about three times faster than typing.
Start in the right directory or Claude will work half-blind
Next is a practical but often-missed habit: Claude Code works from wherever you launch it, so opening it in the wrong place means it can’t properly see your files. The fix is basic terminal hygiene — cd into the correct project folder before launching Claude — but the creator stresses that this alone reduces confusion, wasted tokens, and bad results.
Project CLAUDE.md: the file that keeps your app’s context loaded
The creator says this may be the most important tip of the bunch: create a project-level CLAUDE.md so Claude always has core context about what it’s working on. He shows one for the This Week in AI project, describing it as a lightweight file that captures important structure and background so Claude doesn’t have to rediscover the project every session.
Global CLAUDE.md: your personal style guide for every session
Then he expands the same idea machine-wide with a global CLAUDE.md, which stores preferences that should apply everywhere. His examples are specific and human: “be concise,” “don’t use m dashes,” “don’t use emojis,” “never ask me clarifying questions,” “make a decision and tell me what you chose,” and “always give me a summary,” all of which noticeably change Claude’s behavior.
/clear and /compact: when the chat gets bloated, clean the room
For long grinding sessions, he recommends two cleanup commands. /clear nukes the conversation and starts fresh, while /compact is the smarter option, compressing the thread into a tight summary so Claude keeps the important bits without dragging around a huge context window full of irrelevant detours.
Custom slash commands and the jump to Computer Use
One workflow changer for him is custom commands: create a text file inside the .claude/commands folder, write instructions in plain English, and that becomes a reusable slash command like /transcript. He closes with Anthropic’s newly released Computer Use feature, showing Claude not just building a This Week in AI website, but opening Chrome, clicking through the app, filling forms, spotting bugs, and effectively acting as both the builder and the QA engineer.
