Hook support not working in IDE extension and Codex app #18090
Description
What version of the Codex App are you using (From “About Codex” dialog)?
26.409.61251
What subscription do you have?
null
What platform is your computer?
windows
What issue are you seeing?
Although maintainers mentioned that hook support is already implemented for the IDE extension and Codex app, I cannot get it to work. The CLI hooks behave correctly, but the same functionality does not trigger in the IDE extension or Codex app.
What steps can reproduce the bug?
config.toml
[features]
codex_hooks = true
hooks.json
"hooks": {
"PostToolUse": [
{
"matcher": "Bash",
"hooks": [
{
"type": "command",
"command": "xxxx'"
}
]
}
]
}
Agent environment：Windows Native
Integrated terminal shell：PowerShell
Actual behavior:
（When using hooks, my scripts will print some logs on txt）
CLI: hook executes as expected.
IDE extension: hook is ignored.
Codex app: hook is ignored.
What is the expected behavior?
Hooks should execute consistently across CLI, IDE extension, and Codex app.

I tried on 3 different machines（windows）, all show the same behavior

This is because hooks were only recently enabled for Windows in the CLI. The version of the CLI that was included in your version of the IDE and app does not yet support it. The next releases will.

Indexed this hook ticket in the umbrella tracker: #21753
Goal: collect the scattered Codex hook requests and bugs into one parity matrix for Full Claude Code Hook Parity (29+), while preserving this issue as the detailed thread for its specific behavior.
