desktop execution-bridge failure occurring on even a two-line command

What version of the Codex App are you using (From “About Codex” dialog)?

What subscription do you have?

Pro 5X

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

The Codex command/tool bridge malfunctioned. Even echo ok incorrectly returned “Output exceeded the available model context,”. Exact error is a desktop execution-bridge failure occurring on even a two-line command.

What steps can reproduce the bug?

Open the Codex desktop app on Windows.

Open the existing project workspace:
C:\Users\....
\codex-plugin-computer-use-openai-bundled-2

Ask Codex to run a minimal command: echo ok

Codex attempts to use the terminal tool.
Instead of returning ok, the tool reports: Output exceeded the available model context and was truncated

Repeat echo ok. The same failure occurs, even though the command produces almost no output.
Open a fresh side task in the same workspace and run echo ok again. The fresh task encounters the same failure.

Fully close and restart the Codex desktop app.
Reopen the workspace and retry the minimal command. The execution bridge remains unavailable or produces the same truncation failure.

Attempt to submit feedback through Codex.

Expected result: the terminal returns ok.
Actual result: Codex reports that the output exceeded the model context, despite the command producing only one short line.

An important detail for the report: the failure occurred with minimal commands, in both the original task and a new side task, and persisted after restarting the desktop app.

What is the expected behavior?
