CLI v0.3.5: --plain mode completes but outputs no review content

[andsykes]

Description

The coderabbit review --plain command completes successfully but outputs no actual review content. This makes the CLI unusable for non-interactive environments like Claude Code.

Environment

• CLI Version: 0.3.5
• OS: macOS (darwin-arm64)
• Authentication: Verified working via coderabbit auth status
• Claude Code Plugin: coderabbit@coderabbit v1.0.0 (enabled)

Steps to Reproduce

1. Navigate to a git repository with changes
2. Run: coderabbit review --plain -t all --base develop

Expected Behavior

The command should output the review findings in plain text format to stdout.

Actual Behavior

The command outputs only status messages, then completes without any review content:

Starting CodeRabbit review in plain text mode...

Connecting to review service
Setting up
Analyzing
Reviewing

Review completed ✔

No findings, suggestions, or review content is printed.

Additional Context

• --prompt-only mode exhibits the same issue
• Interactive mode (without --plain) fails in non-TTY environments with "Raw mode is not supported" error from Ink
• This was discovered while using the CodeRabbit Claude Code integration per https://docs.coderabbit.ai/cli/claude-code-integration

Impact

This bug blocks usage of the CLI integration with Claude Code - the /coderabbit:review skill completes but returns no actionable feedback.
