Cursor Agen 3.0 shell waves

Cursor Agent 3.0.

This is a big story:Cursor Argentina 3.0 ExposureClaude CodeI didn't change a line. I just did it.Global ReplaceI don't know.

Which means Cursor Agent 3.0 is essentially Claude Code.A leather version.I don't know.

Exposure: global replacement

According to exposure information, the "development" of Cursor Agent 3.0 is extremely simple:

# 伪代码示意
find . -type f -name "*.py" -o -name "*.js" -o -name "*.ts" | xargs sed -i 's/Claude Code/Cursor Agent/g'
find . -type f -name "*.py" -o -name "*.js" -o -name "*.ts" | xargs sed -i 's/claude/cursor/g'
find . -type f -name "*.py" -o -name "*.js" -o -name "*.ts" | xargs sed -i 's/Anthropic/Cursor/g'

Core logic:Replace the brand name from Claude Code.And it became Cursor Agent 3.0.

What's Claude Code?

Claude Code. Yes. Anthropic Official AI Programming Tool:

  • OfficialOther Organiser
  • Depth Integration: Integration with Claude Model depth
  • PowerfulCode Generation, Code Interpretation, Bug Repair, Reconstruct
  • Update on an ongoing basis:Anthropic continuous iterative optimization

Claude Code is now.One of the most popular AI programming toolsI don't know.

"Innovative" by Cursor Agent 3.0

Cursor is an independent AI programming tool with its own features:

  • Multimodel support: Support multiple models such as GPT and Claude
  • Smart Completion:Tab Completion
  • Chat Window: Internal AI Chat

But the "Agent" function of Cursor Agent 3.0 was exposed.Direct shell, Claude Code.I don't know.

Evidence of the shell

Evidence provided by exposed persons includes:

  1. The code structure is the same.: File structure, function name fully consistent
  2. Comment unchanged: The note in the code still says Claude Code
  3. Error message is the same: I haven't changed my brand name in the wrong message.
  4. Configure File Match: Profile item, default value identical

It's not "learning." It's...Naked copy.I don't know.

Business logic: why the shell?

Cursor, why are you doing this?

1. Savings in development costs

Claude Code’s Agent function is very mature.Redevelopment takes a lot of time and manpower.I don't know. The direct shell can:

  • 6-12 months of development time saved
  • Saving millions of dollars in research and development costs.
  • Rapidly launching competitive products

2. Market grabbing

The market for programming tools is highly competitive.Speed is more important than original.:

  • Cursor needs to respond quickly to market demand
  • Agent function is the most desired function of the user
  • The shell can go online fast.

3. Technology gap

Claude Code's Agent does lead:

  • Anthropic has deep technological accumulation.
  • Claude Model is dedicated to programming optimization
  • Cursor, it's hard to get past in the short term.

• Ethical and legal issues

Ethical dimension

  • Lack of originality: without their own technology accumulation
  • Misdirect users: an innovation that allows users to think of as Cursor
  • Unfair competitionUnfair for other original tools

Legal level

  • Copyright issues:Claude Code copyright belongs to Anthropic
  • Trademark infringement: The use of similar functions and interfaces may involve trademark issues
  • User ProtocolOther Organiser

User response

After exposure, user reactions polarized:

Supporters

  • "As long as it solves the problem, a shell doesn't matter."
  • "Cursor's Tab Completion is still good."
  • "Commercial competition is normal."

Against

  • "This is a naked copy."
  • "Unfair to the original."
  • "The Cursor will never be used again."
  • "Anthropic should be prosecuted."

Summary

Cursor Agent 3.0. Shell Claude Code, exposed to the AI tool industryCruel reality.:

  • Technology gapOther Organiser
  • Commercial pressure: Cursor needs to quickly introduce the competition function
  • Moral controversy: Shell behaviour is widely controversial
  • User Selection: Users value function or original?

And this is a reminder for the industry:What is the value of originality and innovation in the AI era?

The shell is good, but in the long run, technology accumulation is the moat.

Would you choose Cursor Agent 3.0 or just Claude Code?
