Title: TUI mode silently fails with misleading "no social token found" error (--legacy-ui works)

[okajun35]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

Linux 5.14.0-570.28.1.el9_6.x86_64 - Rocky Linux 9.6 (Blue Onyx)

Expected behaviour

Description

kiro-cli chat (TUI mode) exits immediately with exit code 1, displaying misleading authentication error messages. The --legacy-ui mode works perfectly,
confirming that authentication and the chat engine are functioning correctly.

Environment

• kiro-cli: 2.2.2
• OS: Rocky Linux 9.6
• Virtualization: KVM
• TERM: xterm
• TTY: /dev/pts/1
• Shell: bash

Steps to Reproduce

1. kiro-cli login --use-device-flow → succeeds
2. kiro-cli whoami → shows correct user
3. kiro-cli chat → exits immediately

Expected Behavior

TUI chat interface should start.

Actual Behavior

$ kiro-cli chat -vv
2026-05-07T01:01:54.605520Z INFO q_cli::cli: 542: no social token found
2026-05-07T01:01:54.606142Z INFO q_cli::cli: 560: no idp token found
$ echo $?
1

Workarounds (all work)

• kiro-cli chat --legacy-ui ✅
• echo "hello" | kiro-cli chat ✅ (pipe mode)

Notes

• The error message "no social token found / no idp token found" is misleading. Authentication is verified working via kiro-cli whoami and --legacy-ui mode.
• The actual issue appears to be TUI initialization failure, with incorrect error reporting falling through to an auth check path.
• Tested with both root and non-root users — same result.
• Tested with TERM=xterm-256color — same result.

Actual behaviour

 $ kiro-cli chat -vv 2>&1; echo "exit: $?"
  2026-05-07T01:01:54.605520Z  INFO q_cli::cli: 542: no social token found
  2026-05-07T01:01:54.606142Z  INFO q_cli::cli: 560: no idp token found
  exit: 1

  $ kiro-cli chat --legacy-ui
  (works normally - chat interface starts)

verified working via kiro-cli whoami
