Feedback: Incredible experience using Claude Code to contribute to sandbox-runtime

[abe238]

Experience Summary

I just had an incredible experience using Claude Code to contribute to the @anthropic-ai/sandbox-runtime project. The workflow was seamless and deeply impressive.

What Happened

1. Problem Discovery: I encountered a setRawMode EPERM error when trying to run Claude Code inside srt (sandbox-runtime)

2. Deep Analysis: Claude Code helped me:

   • Explore the sandbox-runtime codebase
   • Understand the macOS Seatbelt profile generation
   • Discover that allowPty functionality already existed but wasn't exposed to users

3. Solution Design: Using sequential thinking, we:

   • Proposed 3 different solutions
   • Conducted adversarial debate on each approach
   • Selected the best option (explicit --tty CLI flag)

4. Implementation: Claude Code then:

   • Forked the repository
   • Created a feature branch
   • Implemented the --tty flag (~30 lines of code)
   • Updated README documentation
   • Built and tested the changes
   • Created a well-documented PR with detailed technical analysis

• Pull Request: feat: add --tty flag for interactive terminal applications anthropic-experimental/sandbox-runtime#77
• Detailed Analysis Comment: feat: add --tty flag for interactive terminal applications anthropic-experimental/sandbox-runtime#77 (comment)

What Made This Special

1. End-to-end ownership: From problem identification → research → solution design → implementation → PR submission
2. Deep reasoning: The adversarial analysis of solutions felt like pair programming with a senior engineer
3. Humble contribution: The goal was adding genuine value to open source, not just generating code
4. Documentation: The PR includes extensive reasoning so future maintainers understand the "why"

The Irony

Claude Code helped fix a limitation in the very sandbox that wraps Claude Code. 🤯

Thank you for building such an incredible tool. This experience genuinely felt like the future of software development.
