## Summary
- make the shared `ToolExecutor::is_mutating` default conservative by
returning `true`
- update the trait docs to say read-only tools should opt out explicitly
- add a regression test covering the default behavior
## Why
Hosts use this signal for serialization and approval policy. Treating
unknown contributed tools as read-only lets a write-capable tool
accidentally bypass mutating-tool safeguards if it forgets to override
the hook.
## Validation
- not run, per request
## Why
The tool-extraction work needs one shared executable-tool seam that
hosts and tool owners can depend on without reaching into `codex-core`.
Landing that seam first makes the later tool-family ports incremental
and keeps the reusable contract separate from any one migration.
## What changed
- add a new `codex-tool-api` crate and workspace wiring
- move the common executable-tool contracts into that crate:
`ToolBundle`, `ToolDefinition`, `ToolExecutor`, `ToolCall`, `ToolInput`,
`ToolOutput`, `JsonToolOutput`, and `ToolError`
- keep host state generic through `ToolBundle<C>` / `ToolCall<C>` so
later integrations can provide their own runtime context without baking
core types into the API
- carry the host signals the runtime will need later, including
parallel-call support and mutability probing
- leave existing tool families in place for now; this PR only
establishes the reusable API surface
- add the Bazel target and lockfile updates for the new crate
## Testing
- `cargo test -p codex-tool-api`
## Why
Git commit attribution is prompt policy, not session orchestration.
After #21737 adds the extension-registry seam, this moves that
prompt-only behavior out of `codex-core` so `Session` can consume
extension-contributed prompt fragments instead of owning a one-off
policy path itself.
Before this PR, `Session` injected the trailer instruction directly from
`codex-core` ([session
assembly](a57a747eb6/codex-rs/core/src/session/mod.rs (L2733-L2739)),
[helper
module](a57a747eb6/codex-rs/core/src/commit_attribution.rs (L1-L33))).
This branch moves that same responsibility into
[`codex-git-attribution`](b5029a6736/codex-rs/ext/git-attribution/src/lib.rs (L14-L100)).
## What changed
- Added the `codex-git-attribution` extension crate.
- Snapshot `CodexGitCommit` plus `commit_attribution` at thread start,
then contribute the developer-policy fragment through the extension
registry.
- Register the extension in app-server thread extensions.
- Remove the old `codex-core` helper module and direct `Session`
injection path.
This keeps the existing behavior intact: the prompt is only contributed
when `CodexGitCommit` is enabled, blank attribution still disables the
trailer, and the default remains `Codex <noreply@openai.com>`.
## Stack
- Stacked on #21737.
## Why
[#21736](https://github.com/openai/codex/pull/21736) introduces the
typed extension API, but the runtime does not yet carry a registry
through thread/session startup or give contributors host-owned stores to
read from. This PR wires that host-side path so later feature migrations
can move product-specific behavior behind typed contributions without
adding another bespoke seam directly to `codex-core`.
## What changed
- Thread `ExtensionRegistry<Config>` through `ThreadManager`,
`CodexSpawnArgs`, `Session`, and sub-agent spawn paths.
- Wire `ThreadStartContributor` and `ContextContributor`
- Expose the small supporting surface needed by non-core callers that
construct threads directly, including `empty_extension_registry()`
through `codex-core-api`.
This PR lands the host plumbing only: the app-server registry is still
empty, and concrete feature migrations are intended to follow
separately.
## Why
`codex-core` still owns a growing amount of product-specific behavior.
This PR starts the extraction path by introducing a small, typed
first-party extension seam: features can install the contribution
families they actually own, while the host keeps lifecycle and state
ownership instead of pushing a broad service locator into the API.
See the `examples/` for illustration
## Known limitations
* Tool contract definition will be shared with core
* Fragments must be extracted
* Missing some contributors
## Summary
- Populate `plugin/list` interface metadata for installed Git-sourced
marketplace plugins from the active cached plugin bundle.
- Preserve marketplace category precedence so list behavior matches
`plugin/read`.
- Keep existing fallback behavior when the cache or manifest is missing
or invalid.
## Test Plan
- `cd codex-rs && just fmt`
- `cd codex-rs && cargo test -p codex-core-plugins
list_marketplaces_installed_git_source_reads_metadata_from_cache_without_cloning`
- `cd codex-rs && cargo test -p codex-app-server
plugin_list_returns_installed_git_source_interface_from_cache`
- `cd codex-rs && just fix -p codex-core-plugins`
- `cd codex-rs && just fix -p codex-app-server`
- `git diff --check`
Server-truth check: OpenAI monorepo app-server generated types already
expose `PluginSummary.interface`, and the webview consumes it for plugin
cards. This PR keeps the protocol/schema unchanged and fills the
existing field from the cached installed bundle for Git-backed
cross-repo plugins.
## Why
The TUI currently treats Markdown tables as ordinary wrapped text, which
makes table-heavy responses hard to read and brittle across narrow panes
and terminal resizes.
This change teaches the TUI to render Markdown tables responsively while
preserving the raw Markdown source needed to re-render streamed and
finalized transcript content after width changes. The goal is to keep
tables legible during streaming, after resize, and once a turn has
finished, without corrupting scrollback ordering.
## What Changed
- add table detection and responsive table rendering in the Markdown
renderer
- render standard tables with Unicode box-drawing borders when the pane
is wide enough
- add a vertical readability fallback for constrained or dense tables so
narrow panes still show each row clearly
- keep links and `<br>` content inside table cells instead of leaking
text outside the table
- avoid table normalization inside fenced or indented code blocks
- preserve raw streamed Markdown source and keep the active table as a
mutable tail until finalization
- consolidate finalized streamed content into source-backed transcript
cells so post-resize re-rendering stays correct
- add snapshot and targeted streaming/resize regression coverage for the
new table behavior
## How to Test
1. Start Codex TUI from this branch.
2. Paste this exact prompt:
`This is a session to test codex, no need to do any thinking, just end
different markdown tables, with columns exploring different markdown
contents, like links, bold italic, code, etc. Make them different sizes,
some 30+ rows, some not and intertwine them with some paragraphs with
complex formatting as well.`
3. Confirm the response includes several Markdown tables mixed with
richly formatted paragraphs.
4. Confirm wide-enough tables render with box-drawing borders instead of
plain wrapped pipe text.
5. Resize the terminal narrower while the answer is still streaming and
confirm the in-progress table stays coherent instead of duplicating
headers or leaving broken scrollback behind.
6. Resize again after the turn finishes and confirm the finalized
transcript re-renders cleanly at the new width.
7. In a narrow pane, verify dense tables fall back to the vertical
per-row layout instead of producing unreadable wrapped columns.
8. Also verify pipe-heavy fenced code blocks still render as code, not
as tables.
Targeted tests:
- `cargo test -p codex-tui table_readability_fallback --no-fail-fast`
- `cargo test -p codex-tui markdown_render --no-fail-fast`
- `cargo test -p codex-tui streaming::controller --no-fail-fast`
- `cargo test -p codex-tui table_resize_lifecycle --no-fail-fast`
## Docs
No developer docs update appears necessary.
## Summary
The issue digest uses recent posts, comments, and reactions to decide
which issues deserve attention. A single active user could previously
raise an issue's apparent importance by commenting or reacting multiple
times in the window.
This changes `codex-issue-digest` so `user_interactions` counts unique
human GitHub users per issue across new issue posts, new comments, and
new reactions. Raw reaction/comment counts are still preserved for
detail output, and the skill guidance now describes `Interactions` as a
unique-human-user count.
## Why
On native Windows, running `/mcp` can leak `taskkill`'s normal
`SUCCESS:` messages into the Codex TUI while the temporary MCP inventory
process tree is being torn down. That corrupts the screen even though
MCP itself is working correctly.
Fixes#20845.
## What Changed
- Redirect the Windows-only MCP teardown `taskkill` subprocess to null
stdio so its console output cannot reach the TUI.
## How to Test
1. On native Windows, configure a stdio MCP server, for example:
```powershell
codex mcp add sequential-thinking -- npx -y
@modelcontextprotocol/server-sequential-thinking
```
2. With the latest released Codex CLI, start Codex and run `/mcp`.
3. Confirm the current behavior: `taskkill` `SUCCESS:` lines appear in
the TUI during the MCP refresh.
4. Switch to this branch's build, start Codex again, and run `/mcp`.
5. Confirm the MCP inventory still renders normally and the `taskkill`
lines no longer appear.
6. Repeat `/mcp` once more on this branch to verify the regression does
not recur on repeated inventory requests.
Targeted tests:
- `cargo test -p codex-rmcp-client`
- `cargo test -p codex-rmcp-client --test process_group_cleanup --quiet`
## Why
Inside tmux, `Shift+Enter` can still reach Codex as a plain `Enter` even
when tmux has extended keys enabled. In `csi-u` tmux panes, Codex needs
to request `modifyOtherKeys` mode 2 so tmux moves the pane from `VT10x`
into extended-key mode and preserves the Shift modifier. Without that
extra request, composer `Shift+Enter` submits the draft instead of
inserting a newline.
Fixes#21699.
## What Changed
- Detect tmux sessions and read the active `extended-keys-format`,
preferring the pane-local value before falling back to the global
option.
- Request `modifyOtherKeys` mode 2 for tmux panes using `csi-u` extended
keys, and reset it when restoring keyboard reporting.
- Add unit coverage for tmux detection, the format gate, and the emitted
`modifyOtherKeys` escape sequence.
## How to Test
1. In tmux, configure:
```tmux
set-option -g extended-keys on
set-option -g extended-keys-format csi-u
```
2. Start Codex in a fresh tmux pane from this branch.
3. From another pane, confirm the Codex pane reports `mode=Ext 2`:
```bash
tmux list-panes -a -F '#{session_name}:#{window_index}.#{pane_index}
mode=#{pane_key_mode} cmd=#{pane_current_command}'
```
4. Type a draft in the composer and press `Shift+Enter`; confirm it
inserts a newline instead of submitting.
5. Also confirm plain `Enter` still submits as before.
Targeted tests:
- `cargo test -p codex-tui`
## Notes
- Manual verification used both real `Shift+Enter` in iTerm2/tmux and
`tmux send-keys ... S-Enter` to confirm the tmux pane changes from
`VT10x` to `Ext 2` and preserves newline behavior.
- On this checkout, the broader `codex-tui` test run currently reaches
unrelated existing failures in `status::tests::*` plus a later stack
overflow in
`tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
### Motivation
- Normalize persisted service tier so selecting the request value
`priority` (or legacy `fast`) is stored as `fast` while preserving
unknown tier IDs and keeping request-time behavior unchanged.
### Description
- Update persistence logic in `codex-rs/core/src/config/edit.rs` so
`ConfigEdit::SetServiceTier` maps request values: `priority`/`fast` ->
`"fast"`, `flex` -> `"flex"`, and leaves unknown strings unchanged.
- Add unit tests in `codex-rs/core/src/config/edit_tests.rs` that verify
a `priority` selection is written to `config.toml` as `"fast"` and that
unknown tiers are preserved.
- Add a config load test in `codex-rs/core/src/config/config_tests.rs`
to ensure `service_tier = "priority"` still resolves to the `priority`
request value at load time.
- Add the required import `use
codex_protocol::config_types::ServiceTier;` to the edited modules.
### Testing
- Ran `just fmt` and `just fix -p codex-core` to apply formatting and
lints and they completed successfully.
- Ran `cargo test -p codex-core --lib service_tier` (focused unit tests
for the change) and the tests passed.
- Ran `cargo test -p codex-protocol` and the protocol test suite passed.
- Note: an initial broader `cargo test -p codex-core service_tier`
invocation matched integration tests and produced unrelated
failures/hangs, so that run was interrupted and the focused `--lib`
unit-test invocation was used instead.

Task](https://chatgpt.com/codex/cloud/tasks/task_i_69ffc5a1262c8321af91b69c9845147f)
## Summary
`ChatWidget` has been carrying several independent domains in one large
state bag: transcript bookkeeping, turn lifecycle, queued input, status
surfaces, connectors, review mode, and protocol dispatch. That makes
otherwise-local changes hard to reason about because unrelated fields
and side effects live beside each other in `chatwidget.rs`.
This is the first cleanup PR in a larger decomposition effort. It does
not try to make `chatwidget.rs` small in one sweep; instead, it
establishes focused state boundaries that later handler, popup,
rendering, and effect-synchronization extractions can build on.
This PR keeps `ChatWidget` as the composition layer while moving focused
state into smaller `codex-tui` modules. The widget still owns effects
that touch the bottom pane, app events, command submission, redraw
scheduling, and terminal-title updates.
## Changes
- Add focused state modules under `codex-rs/tui/src/chatwidget/` for
input queues, turn lifecycle, transcript bookkeeping, status state,
connectors, review mode, and app-server protocol dispatch.
- Update `ChatWidget` to hold grouped state structs and route
input/lifecycle/status operations through those focused helpers.
- Move app-server notification dispatch into `chatwidget/protocol.rs`
while leaving feature handlers and side effects on `ChatWidget`.
- Replace the large manual `ChatWidget` test literal with the normal
constructor plus narrow test overrides, so future state moves do not
require every field to be restated in test setup.
- Update existing tests to access the new grouped state or narrower
helpers without changing snapshot behavior.
## Longer-term direction
Follow-up PRs can continue shrinking `chatwidget.rs` by moving behavior,
not just state, into focused modules:
- Extract input/submission flow, turn/stream handling, and tool-cell
lifecycles into domain modules that call the new state reducers.
- Move popup/settings builders and rendering helpers out of the main
widget file so `ChatWidget` stays focused on composition.
- Reduce direct `BottomPane` mutation by applying domain-specific sync
outputs at clearer boundaries.
## Why
Fixes#16688.
The TUI currently hydrates collab receiver metadata by awaiting
`thread/read` before each active-thread notification is rendered. During
large subagent fan-outs, the embedded app-server can be busy starting
agents and processing spawn work, so those synchronous metadata reads
queue behind the fan-out and block the TUI event loop. That makes the UI
appear frozen even though the underlying agent work can continue.
## What Changed
- Replaced eager `thread/read` metadata hydration on the active
notification path with local receiver-thread caching.
- Kept `ThreadStarted` and picker refreshes as the places that fill in
agent nickname/role metadata when it is available.
- Skipped caching receiver threads that are explicitly reported as
`NotFound`, avoiding live-looking ghost entries for failed stale-agent
calls.
- Added TUI tests covering both local receiver caching and `NotFound`
suppression.
## Verification
- `cargo test -p codex-tui collab_receiver_notification`
- `just fix -p codex-tui`
I also ran the full `cargo test -p codex-tui`; the new test passed, but
the full process later aborted with an unrelated stack overflow in
`tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
# Why
Hooks that need trust review were easy to miss, and the existing TUI
flow made users discover `/hooks` manually before they could decide
whether to inspect or trust them.
# What
- add a startup review prompt for new or changed hooks before normal
composer use
- add a top-level `t` shortcut in `/hooks` to trust every review-needed
hook at once
- make pending-review rows and helper copy use warning styling
## TUI
### Startup review interstitial
```text
Hooks need review
2 hooks are new or changed.
Hooks can run outside the sandbox after you trust them.
› 1. Review hooks
2. Trust all and continue
3. Continue without trusting (hooks won't run)
```
### Top-level `/hooks` page when review is needed
```text
Hooks
Lifecycle hooks from config and enabled plugins.
⚠ 1 hook needs review before it can run.
Event Installed Active Review Description

```
## Why
On light terminal backgrounds, selected rows in several TUI pickers were
rendered with the same bright cyan accent used on dark themes. Against
the light menu surface, that made the current selection hard to
distinguish at a glance.

/>
</td>
</tr></table>
## What changed
- Added a shared background-aware accent style for active/selected TUI
controls.
- Use a darker cyan-family accent on light backgrounds while preserving
the existing bright cyan accent on dark or unknown backgrounds.
- Reused that accent across shared picker rows and the custom
selection-like surfaces that had drifted separately: picker tabs, hooks
browsing, external-agent migration choices, and /keymap affordances.
- Added focused tests for the light/dark accent rule and rendered
selected-row styling.
## How to Test
1. Start Codex in a terminal using a light background theme.
2. Type `/` to open the slash-command picker and move the selection
through a few rows.
3. Confirm that the selected row is visibly colored with strong contrast
instead of blending into the popup surface.
4. Open `/keymap` and confirm the active tab, selected rows, and picker
hint accents use the same light-theme accent treatment.
5. In a dark terminal theme, repeat the slash-picker check and confirm
the existing bright cyan selection styling is preserved.
Targeted tests:
- `cargo test -p codex-tui accent_style_uses_`
- `cargo test -p codex-tui selected_rows_use_the_shared_accent_style`
- `cargo test -p codex-tui
selected_event_rows_use_the_shared_accent_style`
Notes:
- A full `cargo test -p codex-tui` run reached the end of the suite but
hit an unrelated existing stack overflow in
`tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
## Why
Mixed prose lines that contained URLs started taking the URL-preserving
wrapping path, but that path could split ordinary words mid-token. A
follow-up issue remained in scrollback insertion: when already-rendered
indented rows were wrapped again, continuation rows could lose their
margin and fall back to terminal hard wrapping. Together those bugs made
normal Markdown output look broken around links, lists, blockquotes, and
indented content.
Separately, the local argument-comment lint wrappers failed under
environments that set `PYTHONSAFEPATH=1`, because Python no longer adds
the script directory to `sys.path` automatically. That prevented the
lint from reaching Rust callsites at all.
<img width="1778" height="1558" alt="CleanShot 2026-05-09 at 11 51 38"
src="https://github.com/user-attachments/assets/9274d150-1757-4f1a-89ac-5bdc9997d8cb"
/>
## What Changed
- Preserve URL tokens without turning every neighboring prose word into
a character-level split point.
- Add a mixed URL/prose wrapper that keeps ordinary words whole,
preserves leading whitespace, and re-splits long non-URL tokens against
the actual width available on continuation rows.
- Reuse a rendered history row's leading whitespace as the continuation
indent when scrollback insertion has to pre-wrap it again.
- Add regression coverage for markdown wrapping, history-cell rendering,
scrollback continuation margins, leading-indent width accounting, and
continuation-row re-splitting.
- Make both argument-comment lint entrypoints explicitly add their own
directory to `sys.path`, so sibling imports still work when
`PYTHONSAFEPATH=1`.
## How to Test
1. Start Codex and render a long Markdown response that mixes prose with
inline links, blockquotes, lists, and indented code-like text.
2. Confirm that ordinary words next to links stay whole instead of
breaking mid-word.
3. Resize or replay the transcript and confirm wrapped continuation rows
keep their expected left margin for blockquotes, lists, and indented
content.
4. Run the source argument-comment lint from a shell with
`PYTHONSAFEPATH=1` and confirm it starts normally instead of failing to
import `wrapper_common`.
Targeted tests:
- `cargo test -p codex-tui mixed_line --lib`
- `cargo test -p codex-tui preserves_prefix_on_wrapped_rows --lib`
- `cargo test -p codex-tui
agent_markdown_cell_does_not_split_words_after_inline_markdown --lib`
- `cargo test -p codex-tui
mixed_url_markdown_wraps_prose_without_splitting_words_snapshot --lib`
- `python3 tools/argument-comment-lint/test_wrapper_common.py`
- `just argument-comment-lint-from-source -p codex-tui -- --lib`
Notes:
- `cargo test -p codex-tui` currently reaches the new tests
successfully, then still aborts in the pre-existing
`tests::fork_last_filters_latest_session_by_cwd_unless_show_all`
stack-overflow failure.
## Why
[PR #1705](https://github.com/openai/codex/pull/1705) moved
`apply_patch` execution under the configured sandbox and called out the
need for integration coverage. We already covered textual `../` escapes,
but did not have coverage for link aliases that live inside a writable
workspace while pointing at, or aliasing, files visible outside it.
This PR locks in the current sandbox boundary without changing
production write semantics. Symlink escapes into a read-only outside
root should fail and leave the outside file unchanged. Existing hard
links are characterized separately: if a user-created hard link already
exists inside the writable root, sandboxed writes preserve normal
hard-link semantics rather than replacing the link and silently breaking
that relationship.
## What Changed
- Added
`apply_patch_cli_does_not_write_through_symlink_escape_outside_workspace`
to verify `apply_patch` cannot update a symlink that targets a file
outside the writable workspace.
- Added `apply_patch_cli_preserves_existing_hard_link_outside_workspace`
to verify `apply_patch` intentionally writes through an existing hard
link and does not unlink or replace it.
- Added `file_system_sandboxed_write_preserves_existing_hard_link` to
verify sandboxed `fs/writeFile` preserves an existing hard link and
writes the shared inode.
## Testing
- `cargo test -p codex-exec-server file_system_sandboxed_write`
- `cargo test -p codex-core
apply_patch_cli_does_not_write_through_symlink_escape_outside_workspace`
- `cargo test -p codex-core
apply_patch_cli_preserves_existing_hard_link_outside_workspace`

## Why
Service-tier slash commands are built from model-catalog metadata. If
the catalog returns a name like `Fast`, the TUI currently exposes
`/Fast` and exact dispatch expects that casing, which is inconsistent
with the lowercase command style used elsewhere.
## What
- Lowercase service-tier command names when converting catalog tiers
into `ServiceTierCommand` values.
- Add regression coverage that seeds a catalog tier named `Fast` and
expects the generated command to be `fast`.
## Testing
Not run locally per repo instruction; PR CI should run the new
`service_tier_commands_lowercase_catalog_names` coverage.
## Why
The Python SDK previously protected the stdio transport with a single
active turn-consumer guard. That avoided competing reads from stdout,
but it also meant one `Codex`/`AsyncCodex` client could not stream
multiple active turns at the same time. Notifications could also arrive
before the caller received a `TurnHandle` and registered for streaming,
so the SDK needed an explicit routing layer instead of letting
individual API calls read directly from the shared transport.
## What Changed
- Added a private `MessageRouter` that owns per-request response queues,
per-turn notification queues, pending turn-notification replay, and
global notification delivery behind a single stdout reader thread.
- Generated typed notification routing metadata so turn IDs come from
known payload shapes instead of router-side attribute guessing, with
explicit fallback handling for unknown notification payloads.
- Updated sync and async turn streaming so `TurnHandle.stream()`/`run()`
and `stream_text()` consume only notifications for their own turn ID,
while `AsyncAppServerClient` no longer serializes all transport calls
behind one async lock.
- Cleared pending turn-notification buffers when unregistered turns
complete so never-consumed turn handles do not leave stale queues
behind.
- Removed the internal stream-until helper now that turn completion
waiting can register directly with routed turn notifications.
- Updated Python SDK docs and focused tests for concurrent transport
calls, interleaved turn routing, buffered early notifications, unknown
notification routing, async delegation, and routed turn completion
behavior.

## Why
The model-visible `<network>` context currently repeats indentation and
a pair of XML tags for every allowed or denied domain. Large domain sets
spend a surprising amount of prompt budget on that scaffolding instead
of the actual policy values.
## What changed
- Render allowed domains as one comma-separated `<allowed>` value
instead of one element per domain.
- Render denied domains the same way.
- Keep the full allow/deny domain sets model-visible while updating the
serialization and settings-update coverage for the denser shape.
## Example
Before:
```xml
<network enabled="true">
<allowed>api.example.test</allowed>
<allowed>cdn.example.test</allowed>
<denied>blocked.example.test</denied>
</network>
```
After:
```xml
<network enabled="true"><allowed>api.example.test,cdn.example.test</allowed><denied>blocked.example.test</denied></network>
```
## Validation
- `cargo test -p codex-core environment_context`
- `cargo test -p codex-core
build_settings_update_items_emits_environment_item_for_network_changes`
- Ran a local `codex` session with a real network context containing 121
allowed domains and 42 denied domains, then inspected the raw prompt
with `raw_token_viewer_cli.py`. With the same domain set, the rendered
`<network>` section shrank from 7,175 characters across 161 lines to
3,666 characters on one line, and the containing environment-context
block fell from 6,428 tokens to 5,379 tokens.
Expose discoverability and full share principals in share context, carry
roles through save/updateTargets, hydrate local shared plugin reads, and
keep share URLs only under plugin.shareContext.
## Why
The app-server watcher relocation leaves the generic filesystem watcher
as the last watcher-specific implementation still living inside
`codex-core`. Moving that code to a small crate keeps `codex-core`
focused on thread execution and lets app-server depend on the watcher
without reaching back into core for filesystem watching primitives.
This PR is stacked on #21287.
## What changed
- Added a new `codex-file-watcher` crate containing the existing watcher
implementation and its unit tests.
- Updated app-server `fs_watch`, `skills_watcher`, and listener state to
import watcher types from `codex-file-watcher`.
- Removed the `file_watcher` module and `notify` dependency from
`codex-core`.
- Updated Cargo workspace metadata and `Cargo.lock` for the new internal
crate.
## Validation
- `cargo check -p codex-file-watcher -p codex-core -p codex-app-server`

- `just fix -p codex-core`
- `just fix -p codex-app-server`
## Why
PR #21460 reverted the earlier move of skills change watching from
`codex-core` into app-server. This reapplies that boundary change so
app-server owns client-facing `skills/changed` notifications and core no
longer carries the watcher.
## What
- Restore the app-server `SkillsWatcher` and register it from thread
listener setup.
- Remove the core-owned skills watcher and its core live-reload
integration surface.
- Restore app-server coverage for `skills/changed` notifications after a
watched skill file changes.
## Validation
- `cargo test -p codex-app-server --test all

- `cargo test -p codex-core --lib --no-run`
## Why
We'd like SQLite state to become required and load-bearing. As a first
step, let's remove the mechanism that allows us to blow away the SQLite
DB on a version bump, and instead rely on graceful migrations.
The original motivation
([PR](https://github.com/openai/codex/pull/10623)) behind this mechanism
was to care less about backwards compatibility while SQLite was being
landed, but I'd say it's quite important now to keep the data in it.
## What changed
- Make `STATE_DB_FILENAME` and `LOGS_DB_FILENAME` the full canonical
filenames: `state_5.sqlite` and `logs_2.sqlite`.
- Remove `STATE_DB_VERSION` / `LOGS_DB_VERSION` and the helper that
constructed filenames from versions.
- Stop `StateRuntime::init` from scanning for or deleting older SQLite
DB filenames at startup.
- Delete the tests that encoded legacy state/logs DB deletion behavior.
## Verification
- `cargo test -p codex-state`
## Why
Amazon Bedrock Mantle needs a stable client-agent header so requests
from the built-in Bedrock provider can be identified as coming from
Codex for safety stack.
## What changed
- Added `x-amzn-mantle-client-agent: codex` to the built-in Amazon
Bedrock provider default HTTP headers.
## Why
Desktop and mobile Codex clients need a machine-readable way to
bootstrap and manage `codex app-server` on remote machines reached over
SSH. The same flow is also useful for bringing up app-server with
`remote_control` enabled on a fresh developer machine and keeping that
managed install current without requiring a human session.
## What changed
- add the new experimental `codex-app-server-daemon` crate and wire it
into `codex app-server daemon` lifecycle commands: `start`, `restart`,
`stop`, `version`, and `bootstrap`
- add explicit `enable-remote-control` and `disable-remote-control`
commands that persist the launch setting and restart a running managed
daemon so the change takes effect immediately
- emit JSON success responses for daemon commands so remote callers can
consume them directly
- support a Unix-only pidfile-backed detached backend for lifecycle
management
- assume the standalone `install.sh` layout for daemon-managed binaries
and always launch `CODEX_HOME/packages/standalone/current/codex`
- add bootstrap support for the standalone managed install plus a
detached hourly updater loop
- harden lifecycle management around concurrent operations, pidfile
ownership, stale state cleanup, updater ownership, managed-binary
preflight, Unix-only rejection, forced shutdown after the graceful
window, and updater process-group tracking/cleanup
- document the experimental Unix-only support boundary plus the
standalone bootstrap/update flow in
`codex-rs/app-server-daemon/README.md`
## Verification
- `cargo test -p codex-app-server-daemon -p codex-cli`
- live pid validation on `cb4`: `bootstrap --remote-control`, `restart`,
`version`, `stop`
## Follow-up
- Add updater self-refresh so the long-lived `pid-update-loop` can
replace its own executable image after installing a newer managed Codex
binary.
## Why
The environment-backed exec-server transport currently hardcodes 5
second connect and initialize timeouts in `client_transport.rs`. That is
short for SSH-backed stdio environments and remote websocket
environments, and there is currently no way to raise those values from
`CODEX_HOME/environments.toml`.
This stacked follow-up raises the default environment transport timeouts
and lets each configured environment override them in
`environments.toml`.
## What Changed
- raise the default environment transport connect and initialize
timeouts from 5s to 10s
- store concrete timeout values on `ExecServerTransportParams` instead
of hardcoding them in `connect_for_transport(...)`
- add `connect_timeout_sec` and `initialize_timeout_sec` to
`[[environments]]` entries in `environments.toml`
- apply parse-time defaults so runtime transport code receives fully
resolved timeout values
- reject `connect_timeout_sec` on stdio environments because it only
applies to websocket transports
- extend parser tests to cover the new fields and defaults
## Stack
- base: https://github.com/openai/codex/pull/21794
- this PR: configurable environment transport timeouts

## Summary
Support registry-backed remote executors end to end so downstream
services can resolve an executor id into an exec-server URL and make
that environment available to Codex without relying on the legacy cloud
environments flow.
## What changed
- switch remote executor registration to the executor registry bootstrap
contract
- allow named remote environments to be inserted into
`EnvironmentManager` at runtime
- add the experimental app-server RPC `environment/add` so initialized
experimental clients can register those remote environments for later
`thread/start` and `turn/start` selection
## Validation
Ran focused validation locally:
- `cargo test -p codex-exec-server environment_manager_`
- `cargo test -p codex-exec-server
register_executor_posts_with_bearer_token_header`
- `cargo test -p codex-app-server-protocol`
## Why
The app-server daemon work needs two app-server behaviors to be safe
when lifecycle management is driven by a helper process:
- a readiness probe must not become the process-wide client identity
just because it connects first
- a graceful reload signal needs to keep draining active turns even if
it is delivered more than once
## What changed
- Treat `codex_app_server_daemon` initialization as a probe-only client
for process-global originator and user-agent suffix state.
- Distinguish forceable shutdown signals from graceful-only ones, and
treat Unix `SIGHUP` as graceful-only while leaving `SIGTERM` and Ctrl-C
forceable.
- Add regression coverage for daemon probe initialization and repeated
`SIGHUP` delivery while a turn is still running.
## Testing
- `cargo test -p codex-app-server`
- The new daemon-probe and repeated-`SIGHUP` coverage passed.
- The run still failed in the existing
`suite::conversation_summary::get_conversation_summary_by_relative_rollout_path_resolves_from_codex_home`
and
`suite::conversation_summary::get_conversation_summary_by_thread_id_reads_rollout`
tests because their initialize handshake timed out.
- `cargo test -p codex-app-server --test all
suite::conversation_summary::`
- Reproduced the same two existing initialize-timeout failures in
isolation.
## Summary
- make EnvironmentProvider::snapshot path-free and keep providers
focused on provider-owned remote environments
- let provider snapshots request local inclusion via include_local, with
environments.toml including local and CODEX_EXEC_SERVER_URL excluding
local
- move reserved local environment construction into EnvironmentManager
using ExecServerRuntimePaths

## Why
PR CI should test the exact commit that was pushed to the PR branch. By
default, GitHub's `pull_request` event checks out a synthetic merge
commit from `refs/pull/<number>/merge`, so the tested tree can include
an implicit merge with the current base branch instead of matching the
pushed head SHA.
Using the PR head SHA makes each check result correspond to a concrete
commit the author submitted. This also behaves better for stacked PR
workflows, including Sapling stacks and other Git stack tooling: a
middle PR's head commit already contains the lower stack changes in its
tree, without pulling in commits above it or GitHub's temporary merge
ref.
## What Changed
- Set every `actions/checkout` in `pull_request` workflows under
`.github/workflows` to use `github.event.pull_request.head.sha` on PR
events and `github.sha` otherwise.
- Updated `blob-size-policy` to compare
`github.event.pull_request.base.sha` and
`github.event.pull_request.head.sha`, since it no longer checks out
GitHub's merge commit where `HEAD^1`/`HEAD^2` represented the PR range.
## Verification
- Parsed the edited workflow YAML files with Ruby.
- Checked that every checkout block in the `pull_request` workflows has
the PR-head `ref`.
## Summary
Startup tool construction currently depends on connector directory
metadata for `tool_suggest` discoverables. On a cold directory cache,
that can put slow connector-directory requests on the blocking path even
though the tools array only needs directory data for install
suggestions, not for the live connector MCP tools themselves.
This PR keeps the discoverables path off that cold network fetch:
- read connector directory metadata from cache only when building
discoverable tools
- persist connector directory metadata to
`~/.codex/cache/codex_app_directory/<hash>.json` and use it to hydrate
the in-memory cache on later runs before the normal refresh path updates
it
- use connector-directory-specific cache naming to distinguish this
metadata cache from the separate Codex Apps tools-spec cache
This reduces first-turn startup work without changing how live connector
MCP tools are sourced. Longer term, directory-backed install suggestions
should move to a search-based flow so they no longer need to be inlined
into the tools prompt at all.
## Testing
- `cargo test -p codex-connectors`
- `cargo test -p codex-chatgpt`
- `cargo test -p codex-core

## Summary
In https://github.com/openai/codex/pull/21584, we disabled doctests for
crates that lack any doctests. We can enforce that property via `cargo
shear --deny-warnings`: crates that lack doctests will be flagged if
doctests are enabled, and crates with doctests will be flagged if
doctests are disabled.
A few additional notes:
- By adding `--deny-warnings`, `cargo shear` also flagged a number of
modules that were not reachable at all. Some of those have been removed.
- This PR removes a usage of `windows_modules!` (since `cargo shear` and
`rustfmt` couldn't see through it) in favor of simple `#[cfg(target_os =
"windows")]` macros. As a consequence, many of these files exhibit churn
in this PR, since they weren't being formatted by `rustfmt` at all on
main.
- Again, to make the code more analyzable, this PR also removes some
usages of `#[path = "cwd_junction.rs"]` in favor of a more standard
module structure. The bin sidecar structure is still retained, but,
e.g., `windows-sandbox-rs/src/bin/command_runner.rs` was moved to
`windows-sandbox-rs/src/bin/command_runner/main.rs`, and so on.

## Why
The legacy `AfterToolUse` hook path was still wired through core tool
dispatch even though the hooks registry never populated any handlers for
it. The supported hook surface is `PostToolUse`, so the old
infrastructure was dead code on the hot path.
## What changed
- Removed the legacy `AfterToolUse` dispatch from `codex-core` tool
execution.
- Removed the unused legacy hook payload types and exports from
`codex-hooks`.
- Simplified legacy notify handling now that `HookEvent` only carries
`AfterAgent`.
## Validation
- `cargo test -p codex-hooks`
- `cargo test -p codex-core registry`
## Why
`apply_patch` is now a freeform/custom tool. Keeping the old
JSON/function-style registration and parsing path left another way for
models and tests to invoke `apply_patch`, which made the tool surface
harder to reason about.
## What changed
- Removed the `ApplyPatchToolType::Function` variant, JSON `apply_patch`
spec, and handler support for function payloads.
- Kept `apply_patch_tool_type = freeform` as the supported model
metadata path, including Bedrock catalog metadata.
- Migrated `apply_patch` tests and SSE fixtures to custom/freeform tool
calls.

## Summary
TL;DR: teaches `codex-rs` / app-server to request a desktop-provided
attestation token and attach it as `x-oai-attestation` on the scoped
ChatGPT Codex request paths.
## Details
This PR teaches the Codex app-server runtime how to request and attach
an attestation token. It does not generate DeviceCheck tokens directly;
instead, it relies on the connected desktop app to advertise that it can
generate attestation and then asks that app for a fresh header value
when needed.
The flow is:
1. The Codex desktop app connects to app-server.
2. During `initialize`, the app can advertise that it supports
`requestAttestation`.
3. Before app-server calls selected ChatGPT Codex endpoints, it sends
the internal server request `attestation/generate` to the app.
4. app-server receives a pre-encoded header value back.
5. app-server forwards that value as `x-oai-attestation` on the scoped
outbound requests.
The code in this repo is mostly protocol and runtime plumbing: it adds
the app-server request/response shape, introduces an attestation
provider in core, wires that provider into Responses / compaction /
realtime setup paths, and covers the intended scoping with tests. The
signed macOS DeviceCheck generation remains owned by the desktop app PR.

<summary>E2E DeviceCheck validation</summary>
First validated the signed desktop app boundary directly: launched a
packaged signed `Codex.app`, sent `attestation/generate`, decoded the
returned `v1.` attestation header, and validated the extracted
DeviceCheck token with `personal/jm/verify_devicecheck_token.py` using
bundle ID `com.openai.codex`. Apple returned `status_code: 200` and
`is_ok: true`.
Then ran the fuller app + app-server flow. The packaged `Codex.app`
launched a current-branch app-server via `CODEX_CLI_PATH`, and a local
MITM proxy intercepted outbound `chatgpt.com` traffic. The app-server
requested `attestation/generate` from the real Electron app process, and
the intercepted `/backend-api/codex/responses` traffic included
`x-oai-attestation` on both routes:
```text
GET /backend-api/codex/responses Upgrade: websocket x-oai-attestation: present
POST /backend-api/codex/responses Upgrade: none x-oai-attestation: present
```
The captured header decoded to a DeviceCheck token that also validated
with Apple for `com.openai.codex` (`status_code: 200`, `is_ok: true`,
team `2DC432GLL2`).

## Why
`ToolName::display()` made it too easy to flatten tool identity and
accidentally compare rendered strings. Tool identity should stay
structural until a legacy string boundary actually requires the
flattened spelling.
## What
- Removes `ToolName::display()` and relies on the existing `Display`
impl for messages and errors.
- Adds structural ordering for `ToolName` and uses it for
sorting/deduping deferred tools.
- Carries `ToolName` through tool/sandbox plumbing, flattening only at
legacy boundaries such as hook payloads, telemetry tags, and Responses
tool names.
- Updates MCP normalization tests to assert `ToolName` structure instead
of rendered strings.
## Testing
- `cargo test -p codex-mcp test_normalize_tools`
- `cargo test -p codex-core unavailable_tool`
- `just fix -p codex-protocol`
- `just fix -p codex-mcp`
- `just fix -p codex-core`
## Why
Codex assisted-code attribution needs a client-side accepted-code source
that does not upload raw code. This adds a hash-only analytics event
derived from the turn diff so downstream attribution can compare
accepted Codex lines against commit or PR diffs.
## What Changed
- Parse accepted/effective added lines from the final turn diff and emit
`codex_accepted_line_fingerprints` analytics.
- Hash repo, path, and normalized line content before upload; raw code
and raw diffs are not included in the event.
- Chunk large fingerprint payloads and send accepted-line fingerprint
events in isolated requests while preserving normal batching for other
analytics events.
- Canonicalize Git remote URLs before repo hashing so SSH/HTTPS GitHub
remotes join to the same repo hash.
- Add parser coverage for unified diff hunk lines that look like `+++`
or `---` file headers.
## Verification
- `cargo test -p codex-analytics`

## Why
Published Python SDK builds depend on an exact `openai-codex-cli-bin`
runtime package, but the release workflow did not publish that runtime
package to PyPI. That left the SDK packaging story incomplete: release
artifacts could produce Codex binaries, but Python users still needed a
matching wheel carrying the platform-specific runtime and helper
executables.
This PR is stacked on #21787 so release jobs can include helper binaries
in runtime wheels: Linux wheels include `bwrap` for sandbox fallback,
and Windows wheels include the signed sandbox/elevation helpers beside
`codex.exe`.
## What changed
- Builds platform-specific `openai-codex-cli-bin` wheels from signed
release binaries on macOS, Linux, and Windows release runners.
- Packages Linux `bwrap` into musllinux runtime wheels.
- Packages Windows sandbox helper executables into Windows runtime
wheels.
- Uploads runtime wheels as GitHub release assets and publishes them to
PyPI using trusted publishing from the `pypi` GitHub environment.
- Keeps the new Python runtime publish job non-blocking so failures need
follow-up but do not fail the Rust release workflow.
- Pins the PyPA publish action to the `v1.13.0` commit SHA for
reproducible release publishing.
- Documents that runtime wheels are platform wheels published through
PyPI trusted publishing.
## Testing
- `ruby -e 'require "yaml"; ARGV.each { |f| YAML.load_file(f); puts "ok
#{f}" }' .github/workflows/rust-release.yml
.github/workflows/rust-release-windows.yml`
- `git diff --check`
CI is the real end-to-end verification for the release workflow path.

## Why
Some Codex runtime distributions need helper executables beside the main
bundled binary. Linux sandbox fallback needs a packaged `bwrap` when no
suitable system `bwrap` is available, and Windows sandbox/elevation
needs helper executables discoverable beside `codex.exe`. The checked-in
`openai-codex-cli-bin` template already packages everything under
`codex_cli_bin/bin/**`, but the staging script only copied the main
Codex binary into that directory.
This PR adds the generic staging primitive needed by release workflows
to build complete platform runtime wheels without baking
platform-specific helper names into the package template.
## What changed
- Added repeatable `stage-runtime --resource-binary` support so release
workflows can copy extra executables beside the bundled Codex binary.
- Kept resource selection in workflow code, where the platform target is
known.
- Added tests that verify resource binaries are copied into the staged
runtime package, that the wheel include config covers them, and that the
CLI forwards repeated `--resource-binary` values.
## Testing
- `uv run ruff check scripts/update_sdk_artifacts.py
tests/test_artifact_workflow_and_binaries.py`
- `uv run --extra dev pytest
tests/test_artifact_workflow_and_binaries.py::test_stage_runtime_release_copies_resource_binaries

tests/test_artifact_workflow_and_binaries.py::test_stage_runtime_stages_binary_without_type_generation`
Full `tests/test_artifact_workflow_and_binaries.py` still has unrelated
schema-normalization drift in the local checkout.

## Why
The earlier PRs add stdio transport support and the config-backed
environment provider, but the feature remains inert until normal Codex
entrypoints construct `EnvironmentManager` with enough context to
discover `CODEX_HOME/environments.toml`. This final stack PR activates
the provider while preserving the legacy `CODEX_EXEC_SERVER_URL`
fallback when no environments file exists.
**Stack position:** this is PR 5 of 5. It is the product wiring PR that
activates the configured environment provider added in PR 4.
## What Changed
- Thread `codex_home` into `EnvironmentManagerArgs`.
- Change `EnvironmentManager::new(...)` to load the provider from
`CODEX_HOME`.
- Preserve legacy behavior by falling back to
`DefaultEnvironmentProvider::from_env()` when `environments.toml` is
absent.
- Make `environments.toml`-backed managers start new threads with all
configured environments, default first, while keeping the legacy env-var
path single-default.
- Update the app-server, TUI, exec, MCP server, connector, prompt-debug,
and thread-manager-sample callsites to pass `codex_home` and handle
provider-loading errors.
## Self-Review Notes
- The multi-environment startup path is intentionally tied to the
`environments.toml` provider. Using `>1` configured environment as the
only signal would also expand the legacy `CODEX_EXEC_SERVER_URL`
provider because it keeps `local` addressable alongside `remote`.
- The startup environment list is still derived inside
`EnvironmentManager`; the provider only says whether its snapshot should
start new threads with all configured environments.
- The thread-manager sample was updated to pass the current
`ThreadManager::new(...)` installation id argument so the stack compiles
under Bazel.

* Pass installation ID for storage on enrollments server for
deduping/grouping multiple appservers per installation
* Pass installation ID in remoteControl/status/changed events
This does two things:
- We use `persist-credentials: false` everywhere now. This is
unfortunately not the default in GitHub Actions, but it prevents
`actions/checkout` from dropping `secrets.GITHUB_TOKEN` onto disk.
- We interpose (some) template expansions through environment variables.
I've limited this to contexts that have non-fixed values; contexts that
are fixed (like `*.result`) are not dangerous to expand directly inline
(but maybe we should clean those up in the future for consistency
anyways).
This is a medium-risk change in terms of CI breakage: I did a scan for
usage of `git push` and other commands that implicitly use the persisted
credential, but couldn't find any. Even still, some implicit usages of
the persisted credentials may be lurking. Please ping ww@ if any issues
arise.
## Summary
Codex keeps trying to add documentation to the `docs/` directory. With
the exception of app server API documentation, the docs for Codex should
not live in this repo. We don't want the local `docs/` folder to become
a stale shadow of the official docs.
This PR updates `AGENTS.md` to make that boundary explicit and scopes
the existing API documentation guidance to app-server docs/examples. It
also removes the extra `docs/config.md` sections that were recently
added.
## Why
`/fast` was wired as a one-off slash command even though model metadata
now exposes service tiers as catalog data. That meant adding another
tier, such as a slower/cheaper tier, would require more hardcoded TUI
plumbing instead of letting the model catalog drive the available
commands.
This change makes service-tier commands data-driven: each advertised
`service_tiers` entry becomes a `/name` command using the catalog
description, while the request path sends the tier `id` only when the
selected model supports it.
## What Changed
- Removed the hardcoded `/fast` slash-command variant and introduced
dynamic service-tier command items in the composer and command popup.
- Added toggle behavior for service-tier commands: invoking `/name`
selects that tier, and invoking it again clears the selection.
- Preserved the existing Fast-mode keybinding/status affordances by
resolving the current model tier whose name is `fast`, while still
sending the tier request value such as `priority`.
- Persisted service-tier selections as raw request strings so non-fast
tiers can round-trip through config.
- Updated the Bedrock catalog entry to advertise fast support through
`service_tiers` with `id: "priority"` and `name: "fast"`.
- Added defensive filtering in core so unsupported selected service
tiers are omitted from `/responses` requests.
## Validation
- Added/updated coverage for dynamic service-tier slash command lookup,
popup descriptions, composer dispatch, TUI fast toggling, and
unsupported-tier omission in core request construction.
- Local tests were not run per request.
