# Why
When a user interrupts a turn while a hook is still running, the normal
turn status is cleared but the separate live hook row can remain visible
as `Running` because the TUI may never receive a matching
`HookCompleted` event before cancellation. Once the turn itself is
finalized, that turn-scoped live state should not remain on screen.
# What
- clear any still-live `active_hook_cell` during turn finalization
- add a regression snapshot covering an interrupted turn with a visible
`PreToolUse` hook row
# Testing
- `cargo test -p codex-tui interrupted_turn_clears_visible_running_hook`
- attempted `cargo test -p codex-tui` (currently aborts on unrelated
existing stack overflow in
`app::tests::discard_side_thread_removes_agent_navigation_entry`)
# Why
Codex currently negotiates MCP `2025-06-18`, where the client
elicitation capability is represented as an empty object. We were still
serializing `capabilities.elicitation.form`, which belongs to the later
capability shape and can cause strict `2025-06-18` servers to reject
`initialize` with an unrecognized-field error.
This keeps the handshake aligned with the protocol version Codex
actually negotiates and fixes the compatibility regression tracked in
#17492.
# What
- Serialize the client elicitation capability as `elicitation: {}` for
`2025-06-18`.
- Keep elicitation advertised for both Codex Apps and custom MCP
servers.
- Tighten regression coverage so the unit test asserts both the Rust
value and the serialized wire shape.
- Add an app-server integration test that round-trips a form elicitation
from a custom MCP server; the existing connector round-trip continues to
cover the connector path.
# Verification
- `cargo test -p codex-mcp`
- `cargo test -p codex-app-server mcp_server_elicitation_round_trip`
- `cargo test -p codex-app-server
mcp_server_tool_call_round_trips_elicitation`
# Next steps
- Decide whether `tool_call_mcp_elicitation=false` should also suppress
capability advertisement during `initialize`.
- Revisit `form` / `url` capability advertisement when Codex is ready to
negotiate MCP `2025-11-25`, which defines that newer shape.
## Why
Image-view results should be represented as a core-produced turn item
instead of being reconstructed by app-server. At the same time, existing
rollout/history paths still understand the legacy `ViewImageToolCall`
event, so this keeps that event as compatibility output generated from
the new item lifecycle.
## What changed
- Added `TurnItem::ImageView` to `codex-protocol`.
- Emitted image-view item start/completion directly from the core
`view_image` handler.
- Kept `ViewImageToolCall` as a legacy event and generate it from
completed `TurnItem::ImageView` items.
- Kept `thread_history.rs` on the legacy `ViewImageToolCall` replay
path, with `ImageView` item lifecycle events ignored there.
- Updated app-server protocol conversion, rollout persistence, and
affected exhaustive event matches for the new item plus legacy fan-out
shape.

This PR adds marketplace upgrade to the `/plugins` menu so users can
update configured marketplaces. It adds a `Ctrl+U` shortcut on eligible
marketplace tabs, a loading state, and the app-server request flow
needed to perform `marketplace/upgrade`. After a successful upgrade, the
TUI refreshes plugin data, plugin mentions, and user config so updated
marketplace contents show up across the menu and other plugin surfaces.
It also preserves the current marketplace tab on no-op and failure paths
and surfaces backend error details directly in the TUI.
- Add a `Ctrl+U` upgrade option for user-configured marketplace tabs in
`/plugins`
- Show the upgrade footer hint only on upgradeable marketplace tabs
- Show a loading state during `marketplace/upgrade`
- Surface already-up-to-date and per-marketplace failure results from
the backend
- Refresh plugin data, plugin mentions, and user config after successful
upgrades
- Add tests and snapshot updates for the shortcut flow, loading state,
and failure messaging
Steps to test:
1. Add a `/plugin` marketplace to Codex TUI.
2. Open `/plugins`, move to that marketplace tab, and confirm the footer
shows `Ctrl+U` to upgrade.
3. Press `Ctrl+U` and confirm the popup switches into an upgrade loading
state.
4. When the request finishes, confirm you see the expected result:
updated marketplace contents on success, an already-up-to-date message
on no-op, or backend error details on failure. On no-op or failure,
confirm the popup stays on the same marketplace tab.
## Why
`ConfigBuilder::build` performs a large amount of async config loading.
Leaving that entire future on the caller stack makes config startup more
fragile on small runtime worker stacks.
## What changed
- keep `ConfigBuilder::build` as a thin wrapper that boxes the
config-loading future before awaiting it
- move the existing implementation into a private `build_inner` method
so the large async state machine lives on the heap instead of the
runtime thread stack
## Testing
- Not run locally
Fixes https://github.com/openai/codex/issues/20501
## Summary
- add Alt+Enter to the built-in editor newline aliases
- update keymap tests that used Alt+Enter as a custom submit binding now
that it conflicts with newline
- refresh the keymap action-menu snapshot fixture
## Test Plan
- `just fmt`
- `cargo test -p codex-tui keymap::tests`
- `cargo test -p codex-tui bottom_pane::textarea::tests`
- `cargo test -p codex-tui keymap_setup::tests`
- `cargo test -p codex-tui`
- `cargo insta pending-snapshots`
- `git diff --check`
- `just argument-comment-lint`
## Summary
- make selected turn environments the source of truth for session
runtime cwd and MCP runtime environment selection
- keep local/no-selection fallback behavior intact
- add coverage for duplicate selected environments, cwd resolution, and
MCP runtime environment selection
## Validation
- git diff --check
- rustfmt was run on touched Rust files during the implementation
workflow
CI should provide the full Bazel/test signal.

## Summary
- Route loaded `thread/read` + `includeTurns` through
`CodexThread::load_history` / ThreadStore history instead of direct
rollout JSONL reads.
- Add an in-memory ThreadStore regression test covering loaded
`thread/read includeTurns` without a local rollout path.
# Why
`notify` is the remaining compatibility surface from the legacy hook
implementation. The newer lifecycle hook engine now owns the active hook
system, so we should start steering users away from adding new `notify`
configs before removing the old path entirely. This also adds a
lightweight watchpoint for the deprecation so we can see how much legacy
usage remains before the clean drop.
# What
- emit a startup deprecation notice when a non-empty `notify` command is
configured
- emit `codex.notify.configured` when a session starts with legacy
`notify` configured
- emit `codex.notify.run` when the legacy notify path fires after a
completed turn
- mark `notify` as deprecated in the config schema and repo docs
- remove the orphaned `codex-rs/hooks/src/user_notification.rs` file
that is no longer compiled
- add regression coverage for the new deprecation notice
# Next steps
A follow-up PR can remove the legacy notify path entirely once we are
ready for the clean drop. Before then, we can watch
`codex.notify.configured` and `codex.notify.run` to understand the
deprecation impact and remaining active usage. The cleanup PR should
then delete the `notify` config field, the `legacy_notify`
implementation, the old compatibility dispatch types and callsites that
only exist for the legacy path, and the remaining compatibility
docs/tests.
# Testing
- `cargo test -p codex-hooks`
- `cargo test -p codex-config`
- `cargo test -p codex-core emits_deprecation_notice_for_notify`
## Why
This adds a checked-in Codex environment configuration so the repo
exposes a ready-to-run Codex action from the app environment metadata.
## What changed
- Added `.codex/environments/environment.toml` with a generated `Run`
action.
- The action runs the `codex` binary from `codex-rs/Cargo.toml` with
`mcp_oauth_credentials_store=file`.
## Verification
- Not run; configuration-only change.
## Why
Users have asked for a `/ide` command in the TUI so Codex can use the
active IDE session for live context such as the current file, open tabs,
and selected ranges. We already support a similar feature in the Codex
desktop app, so bringing it to the TUI makes sense.
One subtle compatibility constraint is that the injected prompt wrapper
and transcript stripping should match the desktop app and IDE extension.
By using the same `## My request for Codex:` delimiter and hiding the
injected context from transcript rendering the same way, threads created
in the TUI render correctly in desktop and IDE surfaces, and threads
created there replay correctly in the TUI, even when IDE context was
included.
Addresses https://github.com/openai/codex/issues/13834.
## What changed
### Summary
This PR consists of four four pieces:
1. An IPC client that uses a socket (Mac/Linux) or named pipe (Windows)
to talk to the IDE Extension
2. Logic that establishes the IPC connection and requests IDE context
(open files, selection) on demand
3. Logic that injects this context into the user prompt (using the same
technique as the desktop app) and hides the added context when rendering
the prompt in the TUI transcript
4. A new slash command for enabling/disabling this mode and text within
the footer to indicate when it's enabled
### Details
- Added `/ide [on|off|status]` to the TUI, with bare `/ide` toggling IDE
context on or off.
- Added a Rust IDE context client that connects to the local Codex IDE
IPC route as a client and requests context from the IDE extension flow.
- Injected IDE context using the same prompt delimiter and
transcript-stripping convention as the desktop app and IDE extension so
shared threads render consistently across surfaces.
- Added an `IDE context` status-line indicator while the feature is
active and cleared it when enabling or fetching context fails.
- Added handling for multiple selection ranges, oversized selections,
interleaved IPC messages, and transient reconnect timing after quick
toggles.
## Verification
Did extensive manual testing in addition to running automated unit and
regression tests.
To test:
- Launch VS Code (or Cursor) with the IDE extension.
- Open one or more files in the IDE and select a range of text within
one of them.
- Start the TUI.
- Ask the agent which files you have open in your IDE, and it should say
that it does not know.
- Enable `/ide` mode; note that `IDE context` appears in the lower
right.
- Ask the agent what files you have open in your IDE and what text is
selected.
## Why
`codex-app-server` currently owns both request-processing code and
transport implementation details. Splitting the transport layer into its
own crate makes that boundary explicit, reduces the amount of
transport-specific dependency surface carried by `codex-app-server`, and
gives future transport work a narrower place to evolve.
## What changed
- Added `codex-app-server-transport` and moved the existing transport
tree into it, including stdio, unix socket, websocket, remote-control
transport, and websocket auth.
- Moved shared transport-facing message types into the new crate so both
the transport implementation and `codex-app-server` use the same
definitions.
- Kept processor-facing connection state and outbound routing in
`codex-app-server`, with the routing tests moved next to that local
wrapper.
- Updated workspace metadata, Bazel crate metadata, and
`codex-app-server` dependencies for the new crate boundary.
## Validation
- `cargo metadata --locked --no-deps`
- `git diff --check`
- Attempted `cargo test -p codex-app-server-transport`, `cargo test -p
codex-app-server`, `just fix -p codex-app-server-transport`, and `just
fix -p codex-app-server`; all were blocked before compilation by the
existing `packageproxy` resolution failure for locked `rustls-webpki =
0.103.13`.
- Attempted Bazel build / lockfile validation; those were blocked by
external fetch failures against BuildBuddy / GitHub while resolving
`v8`.
## Why
`/goal` is supposed to keep Codex working until the goal is actually
done. The previous continuation logic had two ways to stop early: the
continuation prompt told the model to wait for new input when it felt
blocked, and the runtime suppressed another continuation turn after a
continuation finished without any tool calls.
That made goals stop short even when the agent could still keep making
progress (I received a few reports of this from users). It also relied
on a brittle heuristic that treated "no registry tool calls" as
equivalent to "should stop."
## What changed
- removed the continuation prompt sentence that told the model to stop
and wait for new input when it could not continue productively
- removed the goal runtime suppression heuristic that stopped
auto-continuation after a no-tool continuation turn
- deleted the continuation-activity bookkeeping and left `tool_calls` as
telemetry only
- added focused regressions for the two intended behaviors: completed
no-tool continuation turns still continue, while `request_user_input`
keeps the existing turn open instead of spawning a new continuation
## Why
Issue #20489 calls out that animated TUI affordances can be noisy for
screen-reader users. Codex already has `tui.animations = false` as a
reduced-motion setting, but some live activity rows render spinner-style
prefixes in that mode. These were relatively recent regressions.
We have also regressed this pattern more than once by adding new
spinner/shimmer callsites that do not think through the reduced-motion
path, so this PR adds a small guardrail while fixing the current
surfaces.
## What changed
- Omit the live status-row spinner when animations are disabled, so the
row starts with stable text like `Working (...)`.
- Render running hook headers without the spinner prefix when animations
are disabled, while preserving shimmer/spinner behavior when animations
are enabled.
- Centralize TUI activity indicators in `tui/src/motion.rs`, with
explicit reduced-motion choices for hidden prefixes, static bullets, and
plain shimmer-text fallbacks.
- Route existing spinner/shimmer callsites through the central motion
helper, including exec rows, MCP/web-search/loading rows, hook rows,
plugin loading, and onboarding loading text.
- Add a source-scan regression test that rejects direct `spinner(...)`
or `shimmer_spans(...)` usage outside the central module and primitive
definition.
- Add focused coverage that reduced-motion active exec rows are stable,
status rows start without a spinner, running hooks omit the spinner, and
MCP inventory loading stays stable.
- Update the one affected status-indicator snapshot; the existing detail
tree prefix remains unchanged.
## Verification
- `cargo test -p codex-tui`
## Why
Apply-patch file changes are now part of the core turn item stream, so
v2 clients can consume the same first-class item lifecycle path used by
other turn items instead of relying on app-server-specific remapping
from legacy patch events.
## What changed
- Added a core `TurnItem::FileChange` carrying apply-patch changes and
completion metadata.
- Updated the apply-patch tool emitter to send `ItemStarted` /
`ItemCompleted` with the new `FileChange` item while preserving legacy
`PatchApplyBegin` / `PatchApplyEnd` fan-out.
- Updated app-server v2 conversion to render the new core item directly
and stopped `event_mapping` from remapping old patch begin/end events
into item notifications.
- Kept thread history reconstruction based on the existing old
apply-patch events for rollout compatibility.
## Verification
- `cargo test -p codex-protocol -p codex-app-server-protocol`
- `cargo test -p codex-core --test all
apply_patch_tool_executes_and_emits_patch_events`
- `cargo test -p codex-app-server bespoke_event_handling`
## Why
For reproducibility. A hand-written `config.toml` is not enough to
recreate what a Codex session actually ran with because layered config,
CLI overrides, defaults, feature aliases, resolved feature config,
prompt setup, and model-catalog/session values can all affect the final
runtime behavior.
This PR adds an effective config lockfile path: one run can export the
resolved session config, and a later run can replay that lockfile and
fail early if the regenerated effective config drifts.
## What Changed
- Add a dedicated `ConfigLockfileToml` wrapper with top-level lockfile
metadata plus the replayable config:
```toml
version = 1
codex_version = "..."
[config]
# effective ConfigToml fields
```
- Keep lockfile metadata out of regular `ConfigToml`; replay loads
`ConfigLockfileToml` and then uses its nested `config` as the
authoritative config layer.
- Add `debug.config_lockfile.export_dir` to write
`<thread_id>.config.lock.toml` when a root session starts.
- Add `debug.config_lockfile.load_path` to replay a saved lockfile and
validate the regenerated session lockfile against it.
- Add `debug.config_lockfile.allow_codex_version_mismatch` to optionally
tolerate Codex binary version drift while still comparing the rest of
the lockfile.
- Add `debug.config_lockfile.save_fields_resolved_from_model_catalog` so
lock creation can either save model-catalog/session-resolved fields or
intentionally leave those fields dynamic.
- Build lockfiles from the effective config plus resolved runtime values
such as model selection, reasoning settings, prompts, service tier, web
search mode, feature states/config, memories config, skill instructions,
and agent limits.
- Materialize feature aliases and custom feature config into the
lockfile so replay compares canonical resolved behavior instead of
user-authored alias shape.
- Strip profile/debug/file-include/environment-specific inputs from
generated lockfiles so they contain replayable values rather than the
inputs that produced those values.
- Surface JSON-RPC server error code/data in app-server client and TUI
bootstrap errors so config-lock replay failures include the actual TOML
diff.
- Regenerate the config schema for the new debug config keys.
## Review Notes
The main flow is split across these files:
- `config/src/config_toml.rs`: lockfile/debug TOML shapes.
- `core/src/config/mod.rs`: loading `debug.config_lockfile.*`, replaying
a lockfile as a config layer, and preserving the expected lockfile for
validation.
- `core/src/session/config_lock.rs`: exporting the current session
lockfile and materializing resolved session/config values.
- `core/src/config_lock.rs`: lockfile parsing, metadata/version checks,
replay comparison, and diff formatting.
## Usage
Export a lockfile from a normal session:
```sh
codex -c 'debug.config_lockfile.export_dir="/tmp/codex-locks"'
```
Export a lockfile without saving model-catalog/session-resolved fields:
```sh
codex -c 'debug.config_lockfile.export_dir="/tmp/codex-locks"' \
-c 'debug.config_lockfile.save_fields_resolved_from_model_catalog=false'
```
Replay a saved lockfile in a later session:
```sh
codex -c 'debug.config_lockfile.load_path="/tmp/codex-locks/<thread_id>.config.lock.toml"'
```
If replay resolves to a different effective config, startup fails with a
TOML diff.
To tolerate Codex binary version drift during replay:
```sh
codex -c 'debug.config_lockfile.load_path="/tmp/codex-locks/<thread_id>.config.lock.toml"' \
-c 'debug.config_lockfile.allow_codex_version_mismatch=true'
```
## Limitations
This does not support custom rules/network policies.
## Verification
- `cargo test -p codex-core config_lock`
- `cargo test -p codex-config`
- `cargo test -p codex-thread-manager-sample`
## Summary
Ad-hoc memory notes are written under `memories/extensions/ad_hoc/`, but
the consolidation agent only knows how to interpret an extension when
the extension folder has an `instructions.md`. Seed those instructions
from the memories write pipeline so an enabled memories startup creates
the expected ad-hoc extension layout automatically.
This also moves extension-specific write behavior behind a dedicated
`memories/write/src/extensions/` module. `ad_hoc` owns the seeded
instructions template, while the existing resource-retention cleanup
lives in its own `prune` module so future memory extensions can add
their own write-side setup without growing a flat helper file.
## Changes
- Seed `memories/extensions/ad_hoc/instructions.md` during eligible
memory startup without overwriting an existing file.
- Store the ad-hoc instructions template under
`memories/write/templates/extensions/ad_hoc/`, keeping ownership in
`codex-memories-write`.
- Split memory extension support into `extensions::ad_hoc` and
`extensions::prune`.
- Keep the existing old-resource pruning behavior unchanged.
## Verification
- `cargo test -p codex-memories-write`
- `bazel build //codex-rs/memories/write:write`

When a local plugin is shared, Codex now records the local plugin path
by remote plugin id under CODEX_HOME/.tmp.
plugin/share/list includes the remote share URL and the matching local
plugin path when available, and plugin/share/delete
clears the local mapping after deleting the remote share.
Also add sharedURL to plugin/share/list.
## Summary
Adds an app-server `plugin/skill/read` method for remote plugin skill
markdown. The new method calls the plugin-service skill detail endpoint
and returns `skill_md_contents`, so clients can preview skills for
remote plugins before the bundle is installed locally.
## Why
Uninstalled remote plugin skills do not have local `SKILL.md` files.
Without an on-demand remote read, the desktop plugin details UI cannot
render the skill details modal for those skills.
## Validation
- `just write-app-server-schema`
- `just fmt`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server --test all --

--exact`
- `just fix -p codex-app-server-protocol -p codex-core-plugins -p
codex-app-server`
## Summary
- Refresh the remote installed-plugin cache after login/logout instead
of keying it by account or eagerly clearing it.
- Reuse the existing single-flight remote installed refresh loop so
newer queued auth refreshes replace older pending requests and the API
result eventually overwrites or clears the cache.
- Keep derived plugin/skills cache and MCP refresh side effects behind
the existing effective-plugin-changed task when the refreshed installed
state changes.
- Leave `clear_plugin_related_caches` scoped to derived plugin/skills
caches so share mutations do not drop remote installed plugins.
## Tests
- `cargo fmt --all --manifest-path codex-rs/Cargo.toml` (passes; stable
rustfmt warns that `imports_granularity = Item` is nightly-only)
- `cargo test -p codex-core-plugins remote_installed_cache`
- `cargo test -p codex-app-server
skills_list_loads_remote_installed_plugin_skills_from_cache`
## Why
Users have shared that the TUI can feel too visually flat because themes
mostly show up in code syntax highlighting. The configurable statusline
is a natural place to make the active theme more visible, while still
letting users keep the existing monotone statusline if they prefer it.
## What Changed
- Added a statusline styling helper that builds the rendered statusline
from `(StatusLineItem, text)` segments, preserving item identity while
keeping the plain text output unchanged.
- Derived foreground accent colors from the active syntax theme by
looking up TextMate scopes through the existing syntax highlighter, with
conservative ANSI fallbacks when a scope does not provide a foreground.
- Tuned theme-derived colors to keep the accents visible without making
the statusline feel overly bright.
- Added `[tui].status_line_use_colors`, defaulting to `true`, plus a
separated `/statusline` toggle so users can enable or disable
theme-derived statusline colors from the setup UI.
- Updated the live statusline and `/statusline` preview to use the same
styled builder, while keeping terminal-title preview text plain.
- Kept statusline separators and active-agent add-ons subdued while
removing blanket dimming from the whole passive statusline.

## Why
Goal mode shows elapsed time in compact hour/minute form. That is easy
to scan for shorter runs, but once a goal runs past 24 hours, large hour
counts become harder to read at a glance.
## What changed
Updated `codex-rs/tui/src/goal_display.rs` so unbudgeted goal elapsed
time keeps the existing compact format below one day, then switches to a
day-aware format once the elapsed time reaches 24 hours:
- `23h 59m`
- `1d 0h 0m`
- `2d 23h 42m`
The formatter now covers the 24-hour boundary in unit tests, and the TUI
status-line snapshot for a completed elapsed goal now exercises the
multi-day display.
## Verification
- `cargo test -p codex-tui`
Here's my longest-running test task:

- Build one app-server process ThreadStore from startup config and share
it with ThreadManager and CodexMessageProcessor.
- Remove per-thread/fork store reconstruction so effective thread config
cannot switch the persistence backend.
- Add params to ThreadStore create/resume for specifying thread
metadata, since otherwise the metadata from store creation would be used
(incorrectly).
## Why
Several legacy `EventMsg` variants were still emitted or mapped even
though clients either ignored them or had moved to item/lifecycle
events. `Op::Undo` had also degraded to an unavailable shim, so this
removes that dead task path instead of preserving a command that cannot
do useful work.
`McpStartupComplete`, `WebSearchBegin`, and `ImageGenerationBegin` are
intentionally kept because useful consumers still depend on them: MCP
startup completion drives readiness behavior, and the begin events let
app-server/core consumers surface in-progress web-search and
image-generation items before the final payload arrives.
## What Changed
- Removed weak legacy event variants and payloads from `codex-protocol`,
including legacy agent deltas, background events, and undo lifecycle
events.
- Kept/restored `EventMsg::McpStartupComplete`,
`EventMsg::WebSearchBegin`, and `EventMsg::ImageGenerationBegin` with
serializer and emission coverage.
- Updated core, rollout, MCP server, app-server thread history,
review/delegate filtering, and tests to rely on the useful replacement
events that remain.
- Removed `Op::Undo`, `UndoTask`, the undo test module, and stale TUI
slash-command comments.
- Stopped agent job/background progress and compaction retry notices
from emitting `BackgroundEvent` payloads.

startup TUI tests.
## Summary
Remote plugin-service returns plugin availability separately from a
user's installed/enabled state. This adds `PluginAvailabilityStatus` to
the app-server protocol, propagates remote catalog `status` into
`PluginSummary`, and rejects install attempts for remote plugins marked
`DISABLED_BY_ADMIN` before downloading or caching the bundle.

## Summary
- Surface failed GitHub Actions jobs in the PR babysitter watcher so
Codex can fetch job logs as soon as a job fails, instead of waiting for
the overall workflow run to complete.
- Update babysit-pr skill instructions, GitHub API notes, and heuristics
to prefer direct job log archives before falling back to `gh run view

- Add guardrails requiring explicit user confirmation before posting
replies to human-authored review comments.
- Add guardrails preventing Codex from patching unrelated flaky tests,
CI infrastructure, runner issues, dependency outages, or other failures
not caused by the PR branch.

## Why
Several analytics event families need the same per-thread attribution
state: the app-server client/runtime associated with a thread and, for
lifecycle-oriented events, the thread metadata captured during
initialization. Keeping connection ids and lifecycle metadata in
separate maps made each consumer rebuild the same thread context and
made subagent attribution harder to resolve consistently.
## What changed
- Replaces the separate thread connection and metadata maps with one
reducer-owned `threads` map.
- Routes guardian, compaction, turn-steer, and turn analytics through
shared thread-state lookups while preserving turn-origin attribution for
turn events and request-origin attribution for steer events.
- Lets newly observed spawned subagent threads inherit their parent
thread connection so later thread-scoped analytics can resolve through
the same state model.
- Adds regression coverage for standalone `SubAgentThreadStarted`
publication plus the `SubAgentSource::ThreadSpawn` parent fallback
through a thread-scoped consumer that depends on inherited connection
state.
## Verification

## Why
Remote-control protocol v3 makes segmentation an explicit wire-level
feature. The app-server transport needs to support that protocol
directly so large messages can be chunked, acknowledged, replayed, and
reassembled consistently.
## What changed
- Bump the remote-control websocket protocol version from `2` to `3`.
- Add explicit client/server chunk envelope variants plus chunk-aware
acknowledgements.
- Split oversized outbound server messages into bounded transport
chunks.
- Reassemble ordered inbound client chunks with bounded memory usage and
stream/client invalidation handling.
- Track inbound chunk cursors and outbound ack cursors as `(seq_id,
segment_id)` so duplicate chunks and partial replays behave correctly.
- Add focused coverage for chunk splitting, reassembly, duplicate
suppression, and stream replacement behavior.
## Validation
- Added targeted unit coverage for segmented message handling in
`remote_control`.
- Local validation is currently blocked before compilation because
`packageproxy` does not serve the locked `rustls-webpki 0.103.13`
dependency required by the workspace.
## Summary
Fixes a regression introduced in #10941 so that heredocs do not permit
file redirects to be approved by rules, and adds scenario tests to cover
this behavior.
Previously, heredoc command parsing would allow redirects and
environment variables:
```bash
# commands_for_exec_policy() would parse this via parse_shell_lc_single_command_prefix
PATH=/tmp/bad:$PATH cat <<'EOF' > /tmp/bad/hello.txt
hello
EOF
```
This conflicts with the Codex Rules documentation; heredoc parsing logic
should abide by the same strictness of parsing.
## Tests
- [x] Updated unit tests accordingly
- [x] Added scenario tests for these cases

## Why
On Windows, Codex runs shell commands through a top-level
`powershell.exe -NoProfile -Command ...` wrapper. `execpolicy` was
matching that wrapper instead of the inner command, so prefix rules like
`["git", "push"]` did not fire for PowerShell-wrapped commands even
though the same normalization already happens for `bash -lc` on Unix.
This change makes the Windows shell wrapper transparent to rule matching
while preserving the existing Windows unmatched-command safelist and
dangerous-command heuristics.
## What changed
- add `parse_powershell_command_plain_commands()` in
`shell-command/src/powershell.rs` to unwrap the top-level PowerShell
`-Command` body with `extract_powershell_command()` and parse it with
the existing PowerShell AST parser
- update `core/src/exec_policy.rs` so `commands_for_exec_policy()`
treats top-level PowerShell wrappers like `bash -lc` and evaluates rules
against the parsed inner commands
- carry a small `ExecPolicyCommandOrigin` through unmatched-command
evaluation and expose `is_safe_powershell_words()` /
`is_dangerous_powershell_words()` so Windows safelist and
dangerous-command checks still work after unwrap
- add Windows-focused tests for wrapped PowerShell prompt/allow matches,
wrapper parsing, and unmatched safe/dangerous inner commands, and
re-enable the end-to-end `execpolicy_blocks_shell_invocation` test on
Windows
## Testing
- `cargo test -p codex-shell-command`
# Why
The hooks feature flag should use the concise canonical name `hooks`,
while existing configs that still use `codex_hooks` continue to work
during the rename.
# What
- change the canonical `Feature::CodexHooks` key from `codex_hooks` to
`hooks`
- register `codex_hooks` through the existing legacy-alias path
- update the config schema and canonical config fixtures to prefer
`hooks`
- add regression coverage that both `hooks` and `codex_hooks` resolve to
`Feature::CodexHooks`
# Verification
- `cargo test -p codex-features`
- `cargo test -p codex-core config::schema_tests`
- `cargo test -p codex-core
pre_tool_use_blocks_shell_when_defined_in_config_toml`
- `cargo test -p codex-app-server
hooks_list_uses_each_cwds_effective_feature_enablement`
## Summary
- emit `codex_plugin_installed` after a remote plugin install succeeds
- keep local installs unchanged, but let remote installs override the
analytics `plugin_id` with the backend remote plugin id
(`plugins~Plugin_...`)
- preserve the local/display identity in `plugin_name` and
`marketplace_name`, plus capability metadata from the installed bundle
- add regression coverage for local install analytics, remote install
analytics, and analytics id override serialization
## Testing
- `just fmt`
- `cargo test -p codex-analytics`
- `cargo test -p codex-app-server`
## Why
Codex now has configurable TUI keymaps, but the composer still behaves
like a plain text field. Users who prefer modal editing need a way to
keep Vim muscle memory while drafting prompts, and the keymap picker
needs to expose Vim-specific actions if those bindings are configurable
instead of hardcoded.
## What Changed
- Adds composer Vim mode with insert/normal state, common normal-mode
movement and editing commands, `d`/`y` operator-pending flows, and
mode-aware footer and cursor indicators.
- Adds `/vim`, an optional global `toggle_vim_mode` binding, and
`tui.vim_mode_default` so Vim mode can be toggled per session or enabled
as the default composer state.
- Extends runtime and config keymaps with `vim_normal` and
`vim_operator` contexts, exposes those contexts in `/keymap`, refreshes
the config schema, and validates Vim bindings separately.
- Integrates Vim normal mode with existing composer behavior: `/` opens
slash command entry, `!` enters shell mode, `j`/`k` navigate history at
history boundaries, successful submissions reset back to normal mode,
and paste burst handling remains insert-mode only.
- Teaches the TUI render path to apply and restore cursor style so Vim
insert mode can use a bar cursor without leaving the terminal in that
state after exit.
## Validation
- `cargo test -p codex-tui keymap -- --nocapture` on the keymap/Vim
coverage
- `cargo insta pending-snapshots`
## Docs
This introduces user-facing `/vim`, `tui.vim_mode_default`, and Vim
keymap contexts under `tui.keymap`, so the public CLI configuration and
slash-command docs should be updated before the feature ships.
## Why
When an MCP or app tool is configured with approval mode `approve`
(always allow), users expect that decision to be authoritative. In
guardian auto-review mode, ARC could still return `ask-user`, which then
routed the approval question into guardian with the ARC reason as
context. That meant a tool explicitly configured as always allowed still
went through both safety monitors before running.
This change keeps the existing ARC behavior for non-auto-review
sessions, but avoids the ARC-to-guardian sequence when
`approvals_reviewer = auto_review` and the tool approval mode is
`approve`.
## What changed
- Short-circuit MCP tool approval handling when `approval_mode ==
approve` and `approvals_reviewer == auto_review`.
- Updated the MCP approval regression test so the auto-review case
asserts neither ARC nor guardian is called.
- Preserved existing tests that verify ARC can still block always-allow
MCP tools outside guardian auto-review mode.
## Verification
- `cargo test -p codex-core --lib mcp_tool_call`
## Summary
- Download missing remote installed plugin bundles during app-server
startup and plugin/list refresh.
- Upgrade cached remote installed bundles when the backend installed
version changes.
- Remove stale remote installed bundle caches without writing remote
plugin state into config.toml.
## Review note
This is a clean PR branch cut from the current diff on top of latest
`origin/main`. The diff intentionally has no `codex-rs/core/**` files,
so CODEOWNERS should not request the core-directory owner review from
stale PR history.
## Validation

## Description
Ignore these top-level config keys when loading project-scoped
config.toml files:
```
"openai_base_url",
"chatgpt_base_url",
"model_provider",
"model_providers",
"profile",
"profiles",
"experimental_realtime_ws_base_url",
```
## What changed
- Add a project-local config denylist for credential-routing fields such
as `openai_base_url`, `chatgpt_base_url`, `model_provider`,
`model_providers`, `profile`, `profiles`, and
`experimental_realtime_ws_base_url`.
- Strip those fields from project config layers before they participate
in effective config merging, while leaving safe project-local settings
intact.
- Track ignored project-local keys on config layers and surface a
startup warning telling users to move those settings to user-level
`config.toml` if they intentionally need them.
- Update profile behavior coverage so project-local `profile` /
`profiles` entries are ignored instead of overriding user-level profile
selection.
## Verification

- `cargo test -p codex-core project_profiles_are_ignored`
- `cargo test -p codex-core config::config_loader_tests`
- migrate `thread/turns/list` to ThreadStore. Uses ThreadStore for most
data now but merges in the in-memory state from thread manager
- keep v2 `thread/list` pathless-store friendly by converting
`StoredThread` directly to API `Thread`
- add regression coverage for pathless store history/listing
## Summary
This PR installs a first wave of WFP (Windows Filtering Platform)
filters that reduce the surface area of network egress vulnerabilities
for the Windows Sandbox.
- Add persistent Windows Filtering Platform provider, sublayer, and
filters for the Windows sandbox offline account.
- Install WFP filters during elevated full setup, log failures
non-fatally, and emit setup metrics when analytics are enabled.
- Bump the Windows sandbox setup version so existing users rerun full
setup and receive the new filters.
## What WFP is
Windows Filtering Platform (WFP) is the low-level Windows networking
policy engine underneath things like Windows Firewall. It lets
privileged code install persistent filtering rules at specific network
stack layers, with conditions like "only traffic from this Windows
account" or "only this remote port," and an action like block.
In this change, we create a Codex-owned persistent WFP provider and
sublayer, then install block filters scoped to the Windows sandbox's
offline user account via `ALE_USER_ID`. That means the filters are
targeted at sandboxed processes running as that account, rather than
globally affecting the host.
## Initial filter set
We are starting with 12 concrete WFP filters across a few high-value
bypass surfaces. The table below describes the filter families rather
than one filter per row:
| Area | Concrete filters | Purpose |
| --- | --- | --- |
| ICMP | 4 filters: ICMP v4/v6 on `ALE_AUTH_CONNECT` and
`ALE_RESOURCE_ASSIGNMENT` | Block direct ping-style network reachability
checks from the offline account. |
| DNS | 2 filters: remote port `53` on `ALE_AUTH_CONNECT_V4/V6` | Block
direct DNS queries that bypass our intended proxy/offline path. |
| DNS-over-TLS | 2 filters: remote port `853` on
`ALE_AUTH_CONNECT_V4/V6` | Block encrypted DNS attempts that could
bypass ordinary DNS interception. |
| SMB / NetBIOS | 4 filters: remote ports `445` and `139` on
`ALE_AUTH_CONNECT_V4/V6` | Block Windows file-sharing/network share
traffic from sandboxed processes. |
For IPv4/IPv6 coverage, the port-based filters are installed on both
`ALE_AUTH_CONNECT_V4` and `ALE_AUTH_CONNECT_V6`. ICMP also gets both
connect-layer and resource-assignment-layer coverage because ICMP
traffic is shaped differently from ordinary TCP/UDP port traffic.
## Validation
- `cargo fmt -p codex-windows-sandbox` (completed with existing
stable-rustfmt warnings about `imports_granularity = Item`)
- `cargo test -p codex-windows-sandbox wfp::tests`
- `cargo test -p codex-windows-sandbox` (fails in existing legacy
PowerShell sandbox tests because `Microsoft.PowerShell.Utility` could
not be loaded; WFP tests passed before that failure)
