Operating System

Linux with glibc 2.28 on an x86_64 architecture

Kiro Version

1.22.0

Bug Description

After a clean install of kiro-cli (tested with both the musl ZIP package and AppImage extraction), the CLI’s interactive mode consistently fails with: error: Bad file descriptor (os error 9) Authentication (kiro-cli login) works fine, but running kiro-cli with no arguments causes this error. Subcommands such as login, setup, and settings work normally.

Environment:

OS: Linux (glibc 2.28) Architecture: x86_64 Install method: musl ZIP (kirocli-x86_64-linux-musl.zip) via install.sh kiro-cli --version: 1.22.0 (also happens on 1.21.0) $HOME: /home/martinj15 with symlinks for .aws, .config, .cache, .local pointing to /RTM/martinj15 Terminal: Windows Terminal → SSH with RequestTTY yes TERM: xterm-256color

Steps to Reproduce

1. Remove previous install

rm -f ~/.local/bin/kiro-cli
rm -rf ~/.config/kiro ~/.cache/kiro ~/.aws/sso/cache

2. Download musl ZIP and install

curl -O https://desktop-release.q.us-east-1.amazonaws.com/latest/kirocli-x86_64-linux-musl.zip
unzip kirocli.zip
./kirocli/install.sh
source ~/.bashrc

3. Authenticate

kiro-cli login

4. run interactive kiro-cli
5. observe error error: Bad file descriptor (os error 9)

Expected Behavior

Interactive kiro-cli TUI should open.

Actual Behavior: Fails immediately with "Bad file descriptor (os error 9)".

Additional Notes:

Running within a script pseudo-TTY does not resolve the issue. The error occurs regardless of whether $HOME is overridden to /RTM/martinj15 or kept as /home/martinj15. May be related to STDIN/STDOUT handling in the TUI when using SSH RemoteCommand sessions.
