What issue are you seeing?

Codex CLI: 0.141.0
OS: macOS Ventura 13.7.8 (Intel x86_64)
Terminal: Warp
Model: GPT-5.5

Issue:
When a repository loads a SessionStart hook with code-review-graph context, GPT-5.5 crashes with:

zsh: trace trap codexts

The same repository, machine, and Codex CLI version work correctly with GPT-5.4.

Network diagnostics: OK
WebSocket diagnostics: OK
Authentication: ChatGPT
Installation: Standalone

What steps can reproduce the bug?

1. Open warp terminar
2. enter codex command
3. prompt: usa code-review-graph para tener el contexto del codigo sincronizado con los MD de documentación del repo
4. the cli crash in the step: Voy a usar code-review-graph primero para contrastar la arquitectura y los flujos reales con la documentación Markdown; después identificaré y corregiré desajustes concretos en los .md. • Working (9s • esc to interrupt) › zsh: trace trap codexts

What is the expected behavior?

The behavior expected is wait until the process end and validation using commands.
