What issue are you seeing?

Summary

codex app-server starts successfully and creates a thread with the correct remote workspace, but command execution fails because the tool router rejects an unsupported tool call named exec_commandexec_command.

This prevents Codex App Remote SSH sessions from using the read-only terminal/file tools. The terminal-based Codex CLI works, but the App/app-server path cannot run even simple commands such as pwd or ls -la.

Environment

• Codex CLI version: 0.143.0
• Node version: 22.23.1
• npm version: 10.9.8
• OS: Ubuntu 20.04 x86_64
• Remote mode: Codex App Remote SSH / codex app-server
• Shell: bash
• Project cwd: /mnt/Storage2/home/yangtao/FuncPhos-STR

Reproduction

From the remote server:

cd /mnt/Storage2/home/yangtao/FuncPhos-STR
codex debug app-server send-message-v2 "Run pwd and ls -la. Do not modify files."

### What steps can reproduce the bug?

### What is the expected behavior?

pwd
ls -la

### Additional information

codex --version works.
codex app-server --help works.
The remote workspace path exists and is readable.
The terminal-based Codex CLI can be started from the project directory.
The issue appears specific to the app-server/tool-routing path.
