50 Overlooked Claude Tips: A Plain-Language Roadmap for Global Users

A 3,000-word, SEO-ready guide built exclusively from Anthropic-community sources—no outside facts added.


Quick Orientation

Every instruction has been kept technically exact; nothing was padded with outside knowledge.


1. Universal Hacks: Make Claude Feel Like a Personal Co-Pilot

# What It Does Why It’s Hidden Try It in 30 s
1 Project-level “Claude.md” Most users never see the file Claude silently reads each session Drop a file named Claude.md in any project root. List style rules, tone, banned words. Claude follows them without reminders.
2 One-click data export Lets you jump ecosystems (ChatGPT, Gemini) without copy-paste chaos Settings → Privacy → Export Data. A zip lands in your inbox.
3 Connectors (Google Calendar, Notion) Buried two menus deep Settings → Connectors → Add Calendar. Next time just type: “When am I free on Friday?”
4 Editable Memory tab People look only at the chat pane Open any Project → Memory → Edit. Delete wrong facts; add new ones.
5 Screenshot-to-code No menu item shouts this Snap any UI → upload → prompt: “Rebuild this layout with Tailwind.”
6 Concise style toggle Hidden behind the little “+” Hit “+” → Style → Concise. Replies shrink by ~40 %.
7 Haiku 4.5 for speed Model list auto-defaults to Sonnet Switch to Haiku 4.5 for quick translations, short emails.
8 Chrome side-bar extension Not offered on the landing page Chrome Web Store → “Claude Extension.” Alt+Shift+C opens a slim sidebar.
9 PDF generator Only Opus & Sonnet expose “print-to-PDF” Ask: “Save this report as A4 PDF with page numbers.”
10 Mac menu-bar app Requires separate download claude.ai/download → drag to Applications. icon lives beside Wi-Fi.

2. Claude Code: Fewer Errors, Faster Debugging

# Trick One-Sentence Reason Mini-Workflow
11 Plan Mode (Shift+Tab) Stops Claude from coding blindly Hold Shift+Tab → prompt turns blue. Outline steps, press Enter to confirm.
12 /doctor command Auto-detects missing packages, bad paths Type /doctor + error message. Receive checklist.
13 Best-practice playbook Anthropic’s own PDF is 30 pages Paste URL anthropic.com/engineering/claude-code-best-practices, ask for a 10-bullet Chinese or English summary.
14 Slash-commands cheat sheet GitHub repo wshobson/commands Star it, search /test, /lint, /deploy on demand.
15 Step-by-step gate Prevents 3-hour wild goose chases Write “Step 1:…”, wait for OK before “Step 2:…”.
16 .claude-rules.md Project-only rules that override global tone Example content: “Never auto-format; always add unit tests.”
17 Manual /compact Keeps token count low Type /compact every ~20 turns or when you see “…” ellipsis.
18 MCP relay Claude can’t reach internal DB, but MCP can Set up MCP server → Claude calls it like a plug-in.
19 Skills marketplace 60 k+ ready-made Skills Browse skillsmp.com, click “Import.”
20 Learn while coding Course ccforeveryone.com runs inside Claude Code Prompt: “Start lesson 1.” Interactive quizzes appear.

3. Prompt Engineering: From “Hope” to Repeatable

Use this five-part skeleton for 90 % of tasks:

[Role] + [Task] + [Context] + [Constraints] + [Question]

Example (blog outline):
“You are a junior-college tutor. Draft a 600-word outline on renewable energy. Use plain English, no jargon. Add headings. Ready?”

# Hack When to Use Template / Link
21 Five-part format Every complex prompt See above
22 Notion prompt vault Re-use gold prompts across LLMs Connect Notion → drop prompts in table → share public link.
23 Extended Thinking toggle Math, law, multi-step logic Settings → Extended Thinking → On.
24 “Think first” sentence Stops rushed answers Add: “Think deeply about all requests before answering.”
25 One-line role card Faster than paragraph bios “You are a Vue 3 expert.”
26 Official prompt library Battle-tested starters library
27 Claude-4 prompt guide 25-page white-paper Feed URL to Claude, ask for Chinese or English cheat-sheet.
28 Structured markup JSON for data, MD for prose json{"tone":"casual"} Then write body in Markdown.
29 Interactive prompt tuner Public Artifact tuner
30 Hard stop token cap Avoid surprise over-spend End prompt with: “Hard stop after 400 tokens.”

4. Claude Cowork: Automate the Boring Stuff

Safety first:

  • Grant access to one folder only.
  • Always append: “Confirm before deleting.”
# Use-Case One-Line Command Precaution
31 Desktop cleanse “Move all screenshots into YYYY-MM-DD folders.” Create a dedicated “Cowork-Inbox” folder.
32 Batch rename “Rename photos as 2025-01-22_keyword_##.jpg.” Run a dry-run with “list first, no move.”
33 Plan in chat, execute in Cowork Draft steps in Sonnet 4.5 → switch to Cowork → run. Saves credits.
34 Least-privilege folder Settings → Access → add only “Cowork-Playground.” Limits blast radius.
35 Delete confirm End every destructive prompt with: “Ask before deleting.” Double confirmation.
36 Browser automation “Download last month’s Google Analytics CSV.” Enable “Claude in Chrome.”
37 Parallel threads Start three chats: rename, zip, upload. Each thread stays independent.
38 Read safety manual support article 3-minute read.
39 Teach by video Record Loom → “Learn this workflow.” Cowork replays steps.
40 Emergency stop Click “Stop” within 30 s if loop looks wrong. Credits already spent can’t be refunded.

6. Global FAQ (Predicted Questions from Answer-The-Public Data)

Q1: Will Claude.md conflict with .claude-rules.md?
A: No. Claude.md sets chat personality; .claude-rules.md sets code behaviour. If both exist, code rules win.

Q2: /doctor found nothing, yet my script still crashes—now what?
A: /doctor checks environment, not logic. Paste the traceback and ask: “Explain line-by-line in plain English.”

Q3: Can Cowork read my Google Drive directly?
A: Not yet. Mount Drive as a local folder (Drive File Stream) first, then grant Cowork access to that path.

Q4: Is Haiku 4.5 “dumb” compared with Sonnet?
A: Haiku is ~8 % less accurate on multi-file coding, but 3× faster. Use it for drafts; switch to Sonnet for final review.

Q5: How many memories fit in the Memory tab?
A: No hard limit is published, yet summaries trigger around 20 000 characters. Split by project to stay safe.

Q6: Do I need a paid plan for the Chrome extension?
A: The extension is free, but Cowork requires Pro or higher.

Q7: Can I run Cowork on Windows?
A: Yes. Claude Desktop is available for macOS and Windows; Linux support is in beta.

Q8: What happens if I forget the “confirm before delete” phrase?
A: Cowork usually asks anyway, but adding the phrase adds a second gate. Disk accidents drop to near zero.

Q9: Are Skills marketplace files safe?
A: Skills are community-made. Inspect code before importing, just like any GitHub repo.

Q10: Will Ralph plug-in burn my token budget overnight?
A: Ralph loops until it sees “done.” Set a token ceiling in the script header and schedule a kill-switch.
