Claude Code
人人都是 10x dev
A short view back into the past…
To code with AI:
ChatGPT - Copy and paste to chat
Copilot/Cursor - In editor chat / autocomplete
Vibe coding - v0/lovable/replit, web UI
Understanding codebase - IDK, copilot on web?
Task management - copilot workspace/ codex
MCP/Agent - claude desktop/cursor/etc
Can we have one tool that rules them all?
Welcome back to the command line (not vim)
- https://www.anthropic.com/claude-code
- https://github.com/google-gemini/gemini-cli
- https://github.com/openai/codex
`npm install -g @anthropic-ai/claude-code`
No time to explain, Get on the Demo
Usage - Explore codebase
https://github.com/likecoin/likecoin-op
`List all public api exposed by this service`
Usage - Do a task
https://github.com/likecoin/likecoin-api-public
`Add a slack command that allows manually triggering of the function
triggerNFTIndexerUpdate in the case of a class id or a new book is created in
likecoin protocol, and needs to be refresh`
https://github.com/likecoin/likecoin-api-public/pull/1000
Usage - Debugging
https://likerland-team.sentry.io/issues/67909505
57/?project=4507887589523456&query=is%3Au
nresolved&referrer=issue-stream
TypeError
null is not an object (evaluating
'ke.emitsOptions')
Also provide stack trace as context
Usage - Make new project
https://g.co/gemini/share/7f76a7b19b7d
- Create PRD/GDD with ChatGPT/Claude/Gemini/etc
- Init repo with PRD
- /init
- Implement first item
https://github.com/williamchong/over-bingo/blob/1fd11c6166a7a421b215c6dbd26
d4cd8dd6d0cfc/README.md
Usage - Planning for new feature
https://github.com/williamchong/over-
bingo
`How to refactor to support internet
multiplayer for vs mode? think`
Usage - Impossible refactoring
https://hidedotseek.com/
- Replace uglifyjs with modern build stuff
- Change the prototype syntax to modern es6 class
- Upgrade react :0)
Usage - Repetitive well-defined task
https://github.com/likecoin/nft-book-press/pull/383
- Doesn’t work well if you just tell it to convert all string to i18n
- Split into steps by components and pages
- `Check @components/ and @pages/ one by one, check for any untranslated
hardcode string, translate them into i18n string in json`
Usage - General CLI operations
- Merge all audios into
single audio file
How does it works?
Context - codebase
- Good old linux command (e.g.)
- Use @ to provide file context
Context - Image (multimodal)
Use images by drag and drop (macOS), or use @ file path
Context - Memory
./claude.md
./claude.local.md
~/.claude/claude.md
Lint rule, general instruction, things to remember
/init from README, # for memory mode
Check /memory
Context - Context Window
X Code base
O Session limit
/clear or /compact
Just exit and restart claude
Plan & think mode
Planning mode (Shift + Tab)
Magic word:
- think
- ultrathink
Interactive Prompt
Keep prompting when its working
Esc to Pause the task
Esc Esc to exit the task
Command Security
How to avoid
⚠ Warning: Gemini CLI Deleted My Entire Windows System?
Read vs Write commands
/permissions
Extend capability - Tool & MCP
Claude use bash to call tools
- git, gh, ffmpeg, etc
- Call claude to run custom command with –help for context
Import MCP
- https://docs.anthropic.com/en/docs/claude-code/mcp
Prefer bash tool if well known
