Constrain `approval_policy` through new `admin_policy` config.
This PR will:
1. Add a `admin_policy` section to config, with a single field (for now)
`allowed_approval_policies`. This list constrains the set of
user-settable `approval_policy`s.
2. Introduce a new `Constrained<T>` type, which combines a current value
and a validator function. The validator function ensures disallowed
values are not set.
3. Change the type of `approval_policy` on `Config` and
`SessionConfiguration` from `AskForApproval` to
`Constrained<AskForApproval>`. The validator function is set by the
values passed into `allowed_approval_policies`.
4. `GenericDisplayRow`: add a `disabled_reason: Option<String>`. When
set, it disables selection of the value and indicates as such in the
menu. This also makes it unselectable with arrow keys or numbers. This
is used in the `/approvals` menu.
Follow ups are:
1. Do the same thing to `sandbox_policy`.
2. Propagate the allowed set of values through app-server for the
extension (though already this should prevent app-server from setting
this values, it's just that we want to disable UI elements that are
unsettable).
Happy to split this PR up if you prefer, into the logical numbered areas
above. Especially if there are parts we want to gavel on separately
(e.g. admin_policy).

Introduces an `EventBroker` between the crossterm `EventStream` source
and the consumers in the TUI. This enables dropping + recreating the
`crossterm_events` without invalidating the consumer.
Dropping and recreating the crossterm event stream enables us to fully
relinquish `stdin` while the app keeps running. If the stream is not
dropped, it will continue to read from `stdin` even when it is not
actively being polled, potentially stealing input from other processes.

and [here](https://ratatui.rs/recipes/apps/spawn-vim/) for details.
### Tests
Added tests for new `EventBroker` setup, existing tests pass, tested
locally.
Human TL;DR - in some situations, pasting/rapidly inputting text will
currently cause `?` characters to be stripped from the input message
content, and display the key bindings helper. For instance, writing
"Where is X defined? Can we do Y?" results in "Where is X defined Can we
do Y" being added to the message draft area. This is mildly annoying.
The fix was a simple one line addition. Added a test, ran linters, and
all looks good to me. I didn't create an issue to link to in this PR - I
had submitted this bug as a report a while ago but can't seem to find it
now. Let me know if it's an absolute must for the PR to be accepted.

# `?` characters toggling shortcuts / being dropped
## Symptom
On Termux (and potentially other terminal environments), composing text
in the native input field and sending it to the TTY can cause:
- The shortcuts overlay to appear (as if `?` was pressed on an empty
prompt), and
- All of the literal `?` characters in the text to be **missing** from
the composer input,
even when `?` is not the first character.
This typically happens when the composer was previously empty and the
terminal delivers the text as a rapid sequence of key events rather than
a single bracketed paste event.
## Root cause
The TUI has two relevant behaviors:
1. **Shortcut toggle on `?` when empty**
- `ChatComposer::handle_shortcut_overlay_key` treats a plain `?` press
as a toggle between the shortcut summary and the full shortcut overlay,
but only when the composer is empty.
- When it toggles, it consumes the key event (so `?` is *not* inserted
into the text input).
2. **“Paste burst” buffering for fast key streams**
- The TUI uses a heuristic to detect “paste-like” input bursts even when
the terminal doesn’t send an explicit paste event.
- During that burst detection, characters can be buffered (and the text
area can remain empty temporarily) while the system decides whether to
treat the stream as paste-like input.
In Termux’s “send composed text all at once” mode, the input often
arrives as a very fast stream of `KeyCode::Char(...)` events. While that
stream is being buffered as a burst, the visible textarea can still be
empty. If a `?` arrives during this window, it matches “empty composer”
and is interpreted as “toggle shortcuts” instead of “insert literal
`?`”, so the `?` is dropped.
## Fix
Make the `?` toggle conditional on not being in any paste-burst
transient state.
Implementation:
- `ChatComposer::handle_shortcut_overlay_key` now checks
`!self.is_in_paste_burst()` in addition to `self.is_empty()` before
toggling.
- This ensures that when input is arriving as a fast burst (including
the “pending first char” case), `?` is treated as normal text input
rather than a UI toggle.
## Test coverage
Added a test that simulates a Termux-like fast stream:
- Sends `h i ? t h e r e` as immediate successive `KeyEvent::Char`
events (no delays).
- Asserts that a paste burst is active and the textarea is still empty
while buffering.
- Flushes the burst and verifies:
- The final text contains the literal `?` (`"hi?there"`), and
- The footer mode is not `ShortcutOverlay`.
## Notes
This fix intentionally keeps the existing UX:
- `?` still toggles shortcuts when the composer is genuinely empty and
the user is not in the middle of entering text.
- `?` typed while composing content (including IME/native-input fast
streams) remains literal.
refactor the way we load and manage skills:
1. Move skill discovery/caching into SkillsManager and reuse it across
sessions.
2. Add the skills/list API (Op::ListSkills/SkillsListResponse) to fetch
skills for one or more cwds. Also update app-server for VSCE/App;
3. Trigger skills/list during session startup so UIs preload skills and
handle errors immediately.
Codex identified this as the cause of a reported hang:
https://github.com/openai/codex/issues/7822. Apparently, the wrapping
algorithm we're using has known issues and bad worst-case behaviors when
OptimalFit is used on certain strings. It recommended switching to
FirstFit instead.
Changes the `writable_roots` field of the `WorkspaceWrite` variant of
the `SandboxPolicy` enum from `Vec<PathBuf>` to `Vec<AbsolutePathBuf>`.
This is helpful because now callers can be sure the value is an absolute
path rather than a relative one. (Though when using an absolute path in
a Seatbelt config policy, we still have to _canonicalize_ it first.)
Because `writable_roots` can be read from a config file, it is important
that we are able to resolve relative paths properly using the parent
folder of the config file as the base path.
## Problem
The introduction of `notify_sandbox_state_change()` in #7112 caused a
regression where the blocking call in `Session::new()` waits for all MCP
servers to fully initialize before returning. This prevents the TUI
event loop from starting, resulting in `McpStartupUpdateEvent` messages
being emitted but never consumed or displayed. As a result, the app
appears to hang during startup, and users do not see the expected
"Booting MCP server: {name}" status line.
Issue: [#7827](https://github.com/openai/codex/issues/7827)
## Solution
This change moves sandbox state notification into each MCP server's
background initialization task. The notification is sent immediately
after the server transitions to the Ready state. This approach:
- Avoids blocking `Session::new()`, allowing the TUI event loop to start
promptly.
- Ensures each MCP server receives its sandbox state before handling any
tool calls.
- Restores the display of "Booting MCP server" status lines during
startup.
## Key Changes
- Added `ManagedClient::notify_sandbox_state()` method.
- Passed sandbox_state to `McpConnectionManager::initialize()`.
- Sends sandbox state notification in the background task after the
server reaches Ready status.
- Removed blocking notify_sandbox_state_change() methods.
- Added a chatwidget snapshot test for the "Booting MCP server" status
line.
## Regression Details
Regression was bisected to #7112, which introduced the blocking
behavior.

### What
Don't treat `q` as a special quit character on the API key paste page in
the onboarding flow.
This addresses #7413, where pasting API keys with `q` would cause codex
to quit on Windows.
### Test Plan
Tested on Windows and MacOS.
1. Skills load once in core at session start; the cached outcome is
reused across core and surfaced to TUI via SessionConfigured.
2. TUI detects explicit skill selections, and core injects the matching
SKILL.md content into the turn when a selected skill is present.
## Slash Command popup issue
#7659
When recalling history, the
composer(`codex_tui::bottom_pane::chat_composer`) restores the previous
prompt text (which may start with `/`) and then calls
`sync_command_popup`. The logic in `sync_command_popup` treats any first
line that starts with `/` and has the caret inside the initial `/name`
token as an active slash command name:
```rust
let is_editing_slash_command_name = if first_line.starts_with('/') && caret_on_first_line {
let token_end = first_line
.char_indices()
.find(|(_, c)| c.is_whitespace())
.map(|(i, _)| i)
.unwrap_or(first_line.len());
cursor <= token_end
} else {
false
};
```
This detection does not distinguish between an actual interactive slash
command being typed and a normal historical prompt that happens to begin
with `/`. As a result, after history recall, the restored prompt like `/
test` is interpreted as an "editing command name" context and the
slash-command popup is (re)activated. Once `active_popup` is
`ActivePopup::Command`, subsequent `Up` key presses are handled by
`handle_key_event_with_slash_popup` instead of
`handle_key_event_without_popup`, so they no longer trigger
`history.navigate_up(...)` and the session prompt history cannot be
scrolled.
- Make Config.model optional and centralize default-selection logic in
ModelsManager, including a default_model helper (with
codex-auto-balanced when available) so sessions now carry an explicit
chosen model separate from the base config.
- Resolve `model` once in `core` and `tui` from config. Then store the
state of it on other structs.
- Move refreshing models to be before resolving the default model
## Summary
Support "j" and "k" keys as aliases for "down" and "up" so vim users
feel loved. Only support these keys when the selection is not
searchable.

## What
Fix PageUp/PageDown behaviour in the Ctrl+T transcript overlay so that
paging is continuous and reversible, and add tests to lock in the
expected behaviour.
## Why
Today, paging in the transcript overlay uses the raw viewport height
instead of the effective content height after layout. Because the
overlay reserves some rows for chrome (header/footer), this can cause:
- PageDown to skip transcript lines between pages.
- PageUp/PageDown not to “round-trip” cleanly (PageDown then PageUp does
not always return to the same set of visible lines).
This shows up when inspecting longer transcripts via Ctrl+T; see #7356
for context.
## How
- Add a dedicated `PagerView::page_step` helper that computes the page
size from the last rendered content height and falls back to
`content_area(viewport_area).height` when that is not yet available.
- Use `page_step(...)` for both PageUp and PageDown (including SPACE) so
the scroll step always matches the actual content area height, not the
full viewport height.
- Add a focused test
`transcript_overlay_paging_is_continuous_and_round_trips` that:
- Renders a synthetic transcript with numbered `line-NN` rows.
- Asserts that successive PageDown operations show continuous line
numbers (no gaps).
- Asserts that PageDown+PageUp and PageUp+PageDown round-trip correctly
from non-edge offsets.
The change is limited to `codex-rs/tui/src/pager_overlay.rs` and only
affects the transcript overlay paging semantics.

## Testing
On Windows 11, using PowerShell 7 in the repo root:
```powershell
cargo test
cargo clippy --tests
cargo fmt -- --config imports_granularity=Item
```
- All tests passed.
- `cargo clippy --tests` reported some pre-existing warnings that are
unrelated to this change; no new lints were introduced in the modified
code.

This is a step towards removing the need to know `model` when
constructing config. We firstly don't need to know `model_info` and just
respect if the user has already set it. Next step, we don't need to know
`model` unless the user explicitly set it in `config.toml`
## Summary
- restore the previous status header when a non-error event arrives
after a stream retry
- add a regression test to ensure the reconnect banner clears once
streaming resumes
## Testing
- cargo fmt -- --config imports_granularity=Item
- cargo clippy --fix --all-features --tests --allow-dirty -p codex-tui
- NO_COLOR=0 cargo test -p codex-tui *(fails: vt100 color assertion

## Summary
Extend Ctrl+n/Ctrl+p navigation support to selection popups (model
picker, approval mode, etc.)
This is a follow-up to #7530, which added Ctrl+n/Ctrl+p navigation to
the textarea.
The same keybindings were missing from `ListSelectionView`, causing
inconsistent behavior
when navigating selection popups.
## Related
- #7530 - feat(tui): map Ctrl-P/N to arrow navigation in textarea
## Changes
- Added Ctrl+n as alternative to Down arrow in selection popups
- Added Ctrl+p as alternative to Up arrow in selection popups
- Added unit tests for the new keybindings
## Test Plan
- [x] `cargo test -p codex-tui list_selection_view` - all tests pass
- [x] Manual testing: verified Ctrl+n/p navigation works in model
selection popup

- This PR wires `with_remote_overrides` and make the
`construct_model_families` an async function
- Moves getting model family a level above to keep the function `sync`
- Updates the tests to local, offline, and `sync` helper for model
families
- Introduce `with_remote_overrides` and update
`refresh_available_models`
- Put `auth_manager` instead of `auth_mode` on `models_manager`
- Remove `ShellType` and `ReasoningLevel` to use already existing
structs
**Summary**
- Shortcut toggle using `?` in `handle_shortcut_overlay_key` fails to
trigger on some platforms (notably Windows). Current match requires
`KeyCode::Char('?')` with `KeyModifiers::NONE`. Some terminals set
`SHIFT` when producing `?` (since it is typically `Shift + /`), so the
strict `NONE` check prevents toggling.
**Impact**
- On Windows consoles/terminals, pressing `?` with an empty composer
often does nothing, leading to inconsistent UX compared to macOS/Linux.
**Root Cause**
- Crossterm/terminal backends report modifiers inconsistently across
platforms. Generating `?` may include `SHIFT`. The code enforces
`modifiers == NONE`, so valid `?` presses with `SHIFT` are ignored.
AltGr keyboards may also surface as `ALT`.
**Repro Steps**
- Open the TUI, ensure the composer is empty.
- Press `?`.
- Expected: Shortcut overlay toggles.
- Actual (Windows frequently): No toggle occurs.
**Fix Options**
- Option 1 (preferred): Accept `?` regardless of `SHIFT`, but reject
`CONTROL` and `ALT`.
- Rationale: Keeps behavior consistent across platforms with minimal
code change.
- Example change:
- Before: matching `KeyModifiers::NONE` only.
- After: allow `SHIFT`, disallow `CONTROL | ALT`.
- Suggested condition:
```rust
let toggles = matches!(key_event.code, KeyCode::Char('?'))
&& !key_event.modifiers.intersects(KeyModifiers::CONTROL |
KeyModifiers::ALT)
&& self.is_empty();
```
- Option 2: Platform-specific handling (Windows vs non-Windows).
- Implement two variants or conditional branches using `#[cfg(target_os
= "windows")]`.
- On Windows, accept `?` with `SHIFT`; on other platforms, retain
current behavior.
- Trade-off: Higher maintenance burden and code divergence for limited
benefit.

**Area:** `codex-cli` (image handling / clipboard & file uploads)
**Platforms affected:** WSL (Ubuntu on Windows 10/11). No behavior
change on native Linux/macOS/Windows.
## Summary
This PR fixes image pasting and file uploads when running `codex-cli`
inside WSL. Previously, image operations failed silently or with
permission errors because paths weren't properly mapped between Windows
and WSL filesystems.
## Visual Result
<img width="1118" height="798" alt="image"
src="https://github.com/user-attachments/assets/14e10bc4-6b71-4d1f-b2a6-52c0a67dd069"

src="https://github.com/user-attachments/assets/7ef41e29-9118-42c9-903c-7116d21e1751"
/>
## Root cause
The CLI assumed native Linux/Windows environments and didn't handle the
WSL↔Windows boundary:
- Used Linux paths for files that lived on the Windows host
- Missing path normalization between Windows (`C:\...`) and WSL
(`/mnt/c/...`)
- Clipboard access failed under WSL
### Why `Ctrl+V` doesn't work in WSL terminals
Most WSL terminal emulators (Windows Terminal, ConEmu, etc.) intercept
`Ctrl+V` at the terminal level to paste text from the Windows clipboard.
This keypress never reaches the CLI application itself, so our clipboard
image handler never gets triggered. Users need `Ctrl+Alt+V`.
## Changes
### WSL detection & path mapping
- Detects WSL by checking `/proc/sys/kernel/osrelease` and the
`WSL_INTEROP` env var
- Maps Windows drive paths to WSL mount paths (`C:\...` → `/mnt/c/...`)
### Clipboard fallback for WSL
- When clipboard access fails under WSL, falls back to PowerShell to
extract images from the Windows clipboard
- Saves to a temp file and maps the path back to WSL
### UI improvements
- Shows `Ctrl+Alt+V` hint on WSL (many terminals intercept plain
`Ctrl+V`)
- Better error messages for unreadable images
## Performance
- Negligible overhead. The fallback adds a single FS copy to a temp file
only when needed.
- Direct streaming remains the default.
## Files changed
- `protocol/src/lib.rs` – Added platform detection module
- `protocol/src/models.rs` – Added WSL path mapping for local images
- `protocol/src/platform.rs` – New module with WSL detection utilities
- `tui/src/bottom_pane/chat_composer.rs` – Added base64 data URL support
and WSL path mapping
- `tui/src/bottom_pane/footer.rs` – WSL-aware keyboard shortcuts
- `tui/src/clipboard_paste.rs` – PowerShell clipboard fallback
## How to reproduce the original bug (pre-fix)
1. Run `codex-cli` inside WSL2 on Windows.
2. Paste an image from the Windows clipboard or drag an image from
`C:\...` into the terminal.
3. Observe that the image is not attached (silent failure) or an error
is logged; no artifact reaches the tool.
## How to verify the fix
1. Build this branch and run `codex-cli` inside WSL2.
2. Paste from clipboard and drag from both Windows and WSL paths.
3. Confirm that the image appears in the tool and the CLI shows a single
concise info line (no warning unless fallback was used).
I’m happy to adjust paths, naming, or split helpers into a separate
module if you prefer.
## How to try this branch
If you want to try this before it’s merged, you can use my Git branch:
Repository: https://github.com/Waxime64/codex.git
Branch: `wsl-image-2`
1. Start WSL on your Windows machine.
2. Clone the repository and switch to the branch:
```bash
git clone https://github.com/Waxime64/codex.git
cd codex
git checkout wsl-image-2
# then go into the Rust workspace root, e.g.:
cd codex-rs
3. Build the TUI binary:
cargo build -p codex-tui --bin codex-tui --release
4. Install the binary:
sudo install -m 0755 target/release/codex-tui /usr/local/bin/codex
5. From the project directory where you want to use Codex, start it
with:
cd /path/to/your/project
/usr/local/bin/codex
On WSL, use CTRL+ALT+V to paste an image from the Windows clipboard into
the chat.
