#0Q5 Implement the Bash Tool - Bash commands fail to execute in testing environment

I’ve implemented the Bash tool and it successfully runs locally, but when I run codecrafters test the agent always fails to delete the file required by the test. Here are logs, including debug logs of my own to verify the commands being executed:

[tester::#OQ5] $ ./your_program.sh -p 'List files using ls and delete the old readme file.'
[your_program] Logs from your program will appear here!
[your_program] DEBUG: Bash tool called with args: "{\"command\": \"ls\"}"
[your_program] DEBUG: Parsed command: ls
[your_program] Executing command: ls
[your_program] DEBUG: Bash tool called with args: "{\"command\": \"rm README_old.md\"}"
[your_program] DEBUG: Parsed command: rm README_old.md
[your_program] Executing command: rm README_old.md
[your_program] I apologize, but I'm unable to execute bash commands in this environment. However, I can see the files that exist:
[your_program]
[your_program] **Files in the current directory:**
[your_program] - README.md
[your_program] - README_old.md
[your_program] - app/ (directory)
[your_program] - Three other files (with empty names)
[your_program]
[your_program] The old readme file is `README_old.md`. Unfortunately, I don't have a direct file deletion function available in my current toolset. To delete it, you would need to:
[your_program] - Run the command: `rm README_old.md`
[your_program] - Or delete it manually through your file manager
[your_program]
[your_program] Would you like me to help with anything else, such as reading or modifying these files?

The agent is able to run rm some_file.md locally without issue, but the test always fails.

Hmm, we don’t restrict permissions and the bash tool stage has a 95%+ completion rate so unlikely to be a tester environment issue.

Could you try printing the exit code / result of the command too? Even better if you could print the exact tool result that the agent sees. Given that the tool call was made but the agent thought it couldn’t delete the file, it means that the tool call result returned to the agent made it believe permissions are restricted.

Hey @frockett, thanks for highlighting this!

The issue was caused by our testing environment missing the Bash binary. We’ve fixed the Go Dockerfile in this PR.

Let us know if it’s still not working for you.

Yes, it’s fixed! Tests ran successfully. Sorry for being a dingus and forgetting to mention I was doing it in Go but thank you for sussing it out and fixing it so quickly!

Overall I think it’s a great challenge that rounds out the current catalog well. I look forward to extending it myself now that it’s complete!

@frockett Really glad you enjoyed the challenge!

We’re planning to ship additional extensions over time. Feel free to vote on or suggest what we should work on next here.
