Linux 3.10.0-1160.119.1.el7.x86_64 x86_64 x86_64

What terminal emulator and version are you using (if applicable)?

codex exec --dangerously-bypass-approvals-and-sandbox --skip-git-repo-check "review https://xxx/projects/xxx/repos/xxx/pull-requests/xxx/overview"

What issue are you seeing?

I am running Codex inside a Docker container. With the same command and environment:

• Version 0.118.0 works as expected and completes the PR review workflow
• Version 0.124.0 stops after printing the planned steps and exits early

Command used: codex exec --dangerously-bypass-approvals-and-sandbox --skip-git-repo-check "review https://xxx/projects/xxx/repos/xxx/pull-requests/xxx/overview"

Observed behavior (v0.124.0):

• Codex loads the review workflow and prints planned steps:
  • Fetch PR metadata and state
  • Load comments and dedupe context
  • Inspect diff and impacted code
  • Summarize review findings
• However, it does not actually execute these steps (no API calls, no repo fetch, no diff analysis)
• The process exits immediately afterward with exit code 0

Expected behavior:

• Codex should proceed to fetch PR metadata, load comments, retrieve diff, and perform the review

Actual behavior:

• Codex exits early without performing any actions, and without any error message

This looks like a silent early termination or skipped tool execution rather than a normal failure.

What steps can reproduce the bug?

1. Start a Docker container with Codex CLI installed
2. Install Codex CLI version 0.124.0
3. Run the following command:

codex exec --dangerously-bypass-approvals-and-sandbox --skip-git-repo-check "review https://xxx/projects/xxx/repos/xxx/pull-requests/xxx/overview"

1. Observe the output:

   • Codex prints the planned steps (fetch PR metadata, load comments, inspect diff, etc.)
   • No actual execution is performed (no API calls, no repo fetch, no diff analysis)

2. Check the process exit code:

   • The process exits with code 0

3. Repeat the same steps with Codex CLI version 0.118.0:

   • The workflow executes correctly and completes the PR review

What is the expected behavior?
