`claude` CLI works in interactive shell but fails in direct execution with `Not logged in · Run /login`

[BlockLune]

When using Claude Code in Docker Sandboxes, environment variables are injected via a persistent shell script:

sbx exec -d your_sandbox_name bash -c "cat << 'EOF' > /etc/sandbox-persistent.sh
jq '. + {\"hasCompletedOnboarding\": true}' ~/.claude.json > /tmp/.claude.json && mv /tmp/.claude.json ~/.claude.json
export ANTHROPIC_BASE_URL=your_base_url
export ANTHROPIC_AUTH_TOKEN=your_key
unset ANTHROPIC_API_KEY
EOF"

Behavior observed:

• sbx exec -it your_sandbox_name bash then running claude → works fine.
• sbx exec -it your_sandbox_name claude → fails with Not logged in · Run /login.
• sbx run claude → also fails with Not logged in · Run /login.

Expected behavior:

claude CLI should respect the environment variables and login state regardless of whether it is run inside an interactive shell or directly.

Additional context:

Run sbx run claude, then use ! to run external commands. I got this:
