What issue are you seeing?

Component: Codex CLI / local shell tool execution
Codex version: codex-cli 0.145.0
gh version: gh version 2.96.0 (2026-07-02)
Platform: macOS Darwin 25.5.0 arm64

Issue:
When Codex runs gh auth status, it reports that the default GitHub token is invalid. Another local coding agent/
session on the same machine is able to see the expected GitHub auth state.

Command run in Codex:
gh auth status

Actual output:
github.com
X Failed to log in to github.com account <my_account> (default)

• Active account: true
• The token in default is invalid.
• To re-authenticate, run: gh auth login -h github.com
• To forget about this account, run: gh auth logout -h github.com -u <my_account>

Expected:
Codex should either:

• access the same valid GitHub CLI credential context as the host environment, or
• clearly document/explain why gh auth differs inside Codex sandbox/tool execution.

What steps can reproduce the bug?

just make him return the output of gh auth status

What is the expected behavior?
