Darwin 23.5.0 arm64 armWhat issue are you seeing?
All local shell, filesystem, and MCP tool
calls fail with unsupported call before
execution.
The issue occurs across multiple
conversations and different working
directories. Text responses and web tools
continue to work. Restarting conversations
and re-authenticating MCP servers did not
resolve it.
Codex CLI: 0.143.0
Binary: /Users/ian/.npm-global/bin/codex
This is not repository-specific. The same
failure occurs outside the original
project directory
What steps can reproduce the bug?
Uploaded thread: 019f451e-a5c5-78c3-aa79-bafe4c26059f
What is the expected behavior?
