JSON passed to `notify` app should include `cwd` or full `environment_context`

What feature would you like to see?

https://github.com/openai/codex/blob/main/docs/config.md says:

## notify

Specify a program that will be executed to get notified about events generated by Codex. Note that the program will receive the notification argument as a string of JSON, e.g.:

{
  "type": "agent-turn-complete",
  "turn-id": "12345",
  "input-messages": ["Rename `foo` to `bar` and update the callsites."],
  "last-assistant-message": "Rename complete and verified `cargo build` succeeds."
}

Wish:

The JSON should also include the cwd entry with the current working directory of the session. This is extremely important. Without it, it’s really hard to perform any meaningful post-processing of a session that issued the notification, especially if multiple codex sessions are running in different folders.

Claude Code has the equivalent functionality in its hooks (it sets an environment variable).

$HOME/.codex/sessions/2025/09/21/rollout-2025-09-21T15-56-36-01996c8f-f08c-7f22-8b0c-73d372453090.jsonl

has this type of record:

{"timestamp":"2025-09-21T13:56:40.873Z","type":"response_item","payload":{"type":"message","role":"user","content":[{"type":"input_text","text":"<environment_context>\n  <cwd>/Users/user/Developer/test</cwd>\n  <approval_policy>never</approval_policy>\n  <sandbox_mode>danger-full-access</sandbox_mode>\n  <network_access>enabled</network_access>\n  <shell>bash</shell>\n</environment_context>"}]}}

So it would be useful if the JSON passed via notification would include the full environment_context, that is:

{
  "approval_policy": "never",
  "cwd": "/Users/user/Developer/test",
  "input-messages": ["Rename `foo` to `bar` and update the callsites."],
  "last-assistant-message": "Rename complete and verified `cargo build` succeeds."
  "network_access": "enabled",
  "sandbox_mode": "danger-full-access",
  "shell": "bash",
  "turn-id": "12345",
  "type": "agent-turn-complete",
}
