1.12 · Các cách khác làm việc với Claude

Mở đầu: Claude là intelligence, không phải một app

Giờ bài cuối của module tools, hãy unpack ý đó.

Cùng Claude intelligence chạy ở nhiều interfaces khác nhau — mỗi cái tailored cho một loại workflow:

• Terminal / IDE cho developers → Claude Code
• Slack workspace cho team collab → Claude in Slack
• Microsoft Excel cho spreadsheet work → Claude for Excel
• Chrome browser cho web research + automation → Claude for Chrome

Tại sao quan trọng? Vì switching tool cost real time + attention. Bạn đang code trong terminal, muốn ask Claude → open browser, tab Claude.ai, type, copy answer, paste back terminal. Each switch: 30 giây + re-focus mental overhead.

Claude flavors specialized eliminate the switch. Claude ở đúng nơi bạn đang work.

Bài này: quick tour của 4 specialized flavors, với tiêu chí rõ ràng khi nào pick cái nào.

Claude Code

Claude Code là agentic coding tool that works ở đâu bạn work — terminal, IDE, browser, even Slack. It understands codebase, executes commands, handles entire development workflows qua natural language.

Đây không phải copy-paste-AI-chat

Traditional: Copy code vào ChatGPT → copy response → paste back editor → test → repeat.

Claude Code: Claude directly edits files, runs tests, creates commits trong codebase của bạn. Bạn delegate task, Claude execute.

Khi nào dùng Claude Code?

1. Build features qua natural language

Add user authentication với email + password. Use our existing auth pattern trong /auth folder. Write tests. Don't commit

I'll review first."

Claude:

• Reads existing auth code
• Writes new feature matching pattern
• Generates tests
• Shows diff, awaits approval

2. Debug issues

Tests fail trên branch main. Here's error message: [paste]. Investigate + fix.

Claude:

• Analyzes codebase
• Identifies root cause
• Proposes fix với explanation
• Applies if you approve

3. Navigate unfamiliar codebase

This is legacy codebase I inherited. Explain: how does user registration flow work? Which files involved?

Claude:

• Traces code paths
• Explains architecture
• Highlights key files

4. Automate tedious tasks

• Fix lint errors across 50 files
• Resolve merge conflicts
• Write release notes from commits
• Rename variables across entire project

5. Stay in terminal workflow

Prefer terminal over web? Claude Code lives ở đó. No context switch to browser.

Setup

• Download + cài từ claude.com/code (xem hướng dẫn hiện hành trên trang đó)
• Login với Claude account
• Mở trong project folder → start chatting

Works với:

• Terminal (main)
• IDE extensions (VS Code, JetBrains)
• Claude Desktop Code tab (xem Bài 04)
• Browser (claude.ai/code)
• Slack (@Claude in code discussions)

Caveats

• Not for non-dev tasks. Marketing copy → Chat. Code → Claude Code.
• Local code privacy: trong Local mode, code doesn't leave machine. Cloud mode syncs repo.
• Accountability: Claude writes code, but you ship. Review, especially production changes.

Claude in Slack

Claude integrates directly với Slack — get help trong channels + threads, bring Slack context vào Claude conversations.

2 access methods

1. AI assistant header

Mọi channel / DM có AI assistant header — click → chat với Claude riêng tư từ context đó.

2. @Claude mentions trong threads

Mention @Claude trong channel hoặc thread → Claude join conversation visible cho everyone.

Khi nào dùng Claude in Slack?

1. Draft responses

Đang reply to a complex thread. Quickly:

@Claude summarize thread này + draft reply acknowledging concerns, proposing solution.

2. Summarize long threads

@Claude summarize key decisions + action items trong thread này.

3. Break down complex discussions

@Claude tl;dr thread

I'm joining late.

4. Meeting prep

@Claude pull together recent conversations + shared docs about Project X, prepare me cho 2pm meeting.

5. Onboarding

New team member can:

@Claude review #engineering channel history last 30 days. What have people been working on?

6. Hand off coding tasks

Bug report trong #bugs channel. Comment:

@Claude spin up Claude Code session to investigate this. Report back trong thread.

Claude spawn session với surrounding context.

Trade-offs

• Pros: No context switch. Team visibility.
• Cons: Response visible trong channel (unless in DM). Don't post sensitive info.

Setup

• Admin: Install Claude Slack app from Slack marketplace
• User: Follow auth flow
• Usage: @Claude or use AI assistant header

Claude for Excel

Claude for Excel brings Claude directly into Microsoft Excel qua sidebar. Analyze, understand, modify spreadsheets through conversation.

Khi nào dùng Claude for Excel?

1. Understanding complex multi-tab workbook

Inherit workbook 8 sheets, cross-reference formulas.

Explain: how Sheet 3 (P&L) depend trên Sheet 1 (Revenue Assumptions) + Sheet 2 (Cost Inputs)? Show flow.

Claude trace formulas, explain dependencies.

2. Update assumptions preserving dependencies

Model used trong pricing decision. Need update:

Update growth rate Q4 từ 15% → 20%. Preserve all dependent formulas. Update affected cells. Highlight changes.

Claude modify không break model.

3. Debug spreadsheet errors

Cell B45 showing #REF. Trace why + suggest fix." "Circular reference error

find source + resolve."

Claude trace, explain, fix.

4. Create new spreadsheets / populate templates

Build expense tracker: Sheet 1 monthly (categories), Sheet 2 quarterly (roll-up với formulas), Sheet 3 yearly. Include charts.

Claude generates với proper formula structure.

5. Pivot tables + charts

Create pivot: sales by region + product category. Add bar chart visualizing top 5 products each region.

6. Formula explanation

This formula: =INDEX(... MATCH(... MATCH(...)))

explain trong plain English."

Complex formula → understandable.

Why sidebar > chat

Chat với Excel file upload:

• Upload → Claude work trên copy → download new version → manually integrate.
• Breaking integration, awkward.

Claude for Excel sidebar:

• Claude work directly trong your open workbook.
• Changes track, review in-place.
• Save normally via Excel.

Faster, less friction, original file location.

Setup

• Requires Microsoft 365 subscription
• Download Claude for Excel add-in
• Install qua Office Add-ins
• Auth với Claude account

Claude for Chrome

Browser extension. Claude thành sidebar trong Chrome, observe current page, take actions in browser.

Khi nào dùng Claude for Chrome?

1. Summarize while browsing

Articles, research papers, lengthy blog posts:

Summarize 5 key points this page.

No copy-paste.

2. Draft email responses

Viewing email trong Gmail:

Draft reply acknowledging their concerns + proposing call next week.

Claude read email thread context, draft reply in sidebar, you paste hoặc Claude auto-fill.

3. Automate repetitive forms

Filling 20 similar forms (data entry, applications):

Use info from my CSV (attached) to fill form

Name, Email, Company per row."

Claude automate, you approve submissions.

4. Test website features / navigate multi-step workflows

Walk through sign-up flow as test user. Report any errors or UX issues.

Claude navigate, take screenshots, document.

5. Research với maintained context

Compare pricing Competitor A vs. Competitor B. Visit their websites, pull data, output comparison.

Claude visit each, extract, synthesize.

6. Internal tool context

CRM, dashboards, admin tools không có public API:

Pull top 10 customers từ CRM dashboard tôi đang xem. Format into Excel.

Claude scrape visible data.

Research Preview — Important caveats

Claude for Chrome hiện research preview. Anthropic recommend:

• Low-risk tasks + trusted websites
• Extension asks permission before high-risk actions (purchases, sharing personal data)
• Certain categories blocked default: financial services, adult content

Don't use cho:

• Banking / financial transactions
• Sensitive data entry
• High-stakes decisions

Setup

• Chrome Web Store → search "Claude for Chrome"

Anti-patterns

Stick với 1 flavor cho mọi task

Biểu hiện

Use Claude.ai web cho Excel work (upload file, chat, download new version, integrate manually).

Tại sao sai

Claude for Excel sidebar nhanh hơn đáng kể cho Excel tasks — không phải upload/download qua lại.

Cách đúng

Match flavor to context.

Switch flavors unnecessarily

Biểu hiện

Open 5 different Claude flavors concurrently, duplicate work.

Tại sao sai

Confusion. Context fragmented.

Cách đúng

Pick right one for current task. Switch only when task changes.

Use preview features cho production-critical tasks

Biểu hiện

Use Claude for Chrome (research preview) cho financial transactions.

Tại sao sai

Preview = not fully hardened. Mistakes happen.

Cách đúng

Wait cho GA, or use established features. Preview = low-stakes testing.

Forget security posture của mỗi flavor

Biểu hiện

Post sensitive info trong Claude in Slack thread (visible to channel).

Tại sao sai

Privacy leak.

Cách đúng

Sensitive → DM Claude in Slack (private) hoặc Claude.ai. Know each flavor's visibility.

Not testing before committing (Claude Code especially)

Biểu hiện

Claude Code auto-commit, bạn không review diff.

Tại sao sai

AI can make subtle mistakes. Reviewing = your job.

Cách đúng

Default "Ask" or "Plan" mode. Review diffs. Run tests.
