## Background This was prompted by [#26858](https://github.com/openai/codex/issues/26858), where the attached doctor report did not include the editor selection and I had to [ask which editor was in use](https://github.com/openai/codex/issues/26858#issuecomment-4653829891) before investigating the external-editor newline issue. Capturing these variables in doctor makes that context available up front in future reports. `codex doctor` is intended to capture enough local context to diagnose startup and terminal behavior, but it did not report the environment variables that select an external editor or configure command pagers. The TUI [prefers `VISUAL` over `EDITOR`](https://github.com/openai/codex/blob/56554904babcaacf4444a2cc90716880837dff7c/codex-rs/tui/src/external_editor.rs#L31-L38), so missing or unexpected values can explain why the external-editor shortcut fails or launches the wrong command. Pager values are also useful inherited-shell context even though [unified exec normalizes its effective pager variables to `cat`](https://github.com/openai/codex/blob/56554904babcaacf4444a2cc90716880837dff7c/codex-rs/core/src/unified_exec/process_manager.rs#L60-L70). These variables can contain arbitrary command arguments or inline environment assignments. The human report is local, but `codex doctor --json` may be attached to feedback, so the machine-readable report should not include their raw contents. ## What Changed - Report `VISUAL` and `EDITOR` in the system environment details, using `not set` when either variable is absent. - Report inherited `PAGER`, `GIT_PAGER`, `GH_PAGER`, and `LESS` values when present. - Preserve full values in local human output while reducing these fields to `set` or `not set` in redacted JSON output. - Add structured check, JSON-redaction, rendered-output, and snapshot coverage. ## How to Test 1. From `codex-rs`, run Codex with explicit editor and pager variables: ```sh env VISUAL='code --wait' EDITOR=vim PAGER='less -R' GIT_PAGER=delta GH_PAGER=less LESS=-FRX \ cargo run -p codex-cli --bin codex -- doctor --no-color ``` 2. Confirm the `system` details show the full values for all six variables. 3. Unset the pager variables and rerun the command. Confirm pager rows are omitted while missing editor variables are shown as `not set`. 4. Run the same configured environment with `doctor --json`. Confirm each configured editor or pager field is reported as `set` and none of the raw commands or arguments appear in the JSON. Targeted tests: - `just test -p codex-cli` (279 tests passed)
