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
Claude:
2. Debug issues
Claude:
3. Navigate unfamiliar codebase
Claude:
4. Automate tedious tasks
5. Stay in terminal workflow
Prefer terminal over web? Claude Code lives ở đó. No context switch to browser.
Setup
Works với:
Caveats
- Reads existing auth code
- Writes new feature matching pattern
- Generates tests
- Shows diff, awaits approval
- Analyzes codebase
- Identifies root cause
- Proposes fix với explanation
- Applies if you approve
- Traces code paths
- Explains architecture
- Highlights key files
- Fix lint errors across 50 files
- Resolve merge conflicts
- Write release notes from commits
- Rename variables across entire project

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.
