## Why
Legacy `[profiles.<name>]` config tables and the legacy `profile`
selector are being retired in favor of profile files selected with
`--profile <name>`. After #23886 removed the CLI-side legacy profile
plumbing, the app-server config surface still exposed those fields and
still carried conversion code for the old protocol shape.
## What changed
- Remove `profile`, `profiles`, and `ProfileV2` from the app-server
config protocol/schema output so `config/read` no longer returns legacy
profile config.
- Drop the old v1 `UserSavedConfig` profile conversion path from
`config`.
- Reject new app-server config writes under `profiles.*` with the same
migration direction used for `profile`, while still allowing callers to
clear existing legacy profile tables.
- Refresh app-server config coverage and the experimental API README
example around the remaining `Config` nesting path.
## Verification
- Added config-manager coverage that `config/read` omits legacy profile
config, `profiles.*` writes are rejected, and existing legacy profile
tables can still be cleared.
- Updated the v2 config RPC test to cover the rejected `profiles.*`
batch-write path.
## Why
`codex sandbox` previously required an OS subcommand like `linux`,
`macos`, or `windows`, even though the command can only run the sandbox
backend available on the current host. That made the CLI imply a
cross-OS choice that does not exist.
## What changed
- Collapse `codex sandbox <os>` into `codex sandbox [COMMAND]...` by
wiring the `sandbox` parser directly to the host-specific backend args
with `cfg`.
- Keep the existing backend runners for Seatbelt, Linux sandbox, and
Windows restricted token.
- Rename the public Windows debug sandbox runner to
`run_command_under_windows_sandbox` for clarity.
- Update the Rust sandbox docs and related README references to describe
host OS selection and avoid pointing readers at legacy `sandbox_mode`
config.
## Arg0 compatibility
The `codex-linux-sandbox` helper path is still handled before normal CLI
parsing. `arg0_dispatch()` checks whether the executable basename is
`codex-linux-sandbox` and directly calls
`codex_linux_sandbox::run_main()`, so removing the `sandbox linux`
parser branch does not affect the arg0 helper flow.
## Verification
- `cargo test -p codex-cli`
- `cargo test -p codex-arg0`
- `just fix -p codex-cli`
## Why
The TUI currently creates a shared plaintext `codex-tui.log` under the
default log directory. That append-only file can keep growing across
runs even though the TUI already records diagnostics in bounded local
stores.
Make the plaintext file log an explicit troubleshooting choice instead
of a default side effect.
This is possible because logs are also stored in the DB with proper
rotation
## What changed
- Only install the TUI file logging layer when `log_dir` is explicitly
set.
- Remove the prior `codex-tui.log` at startup before an opt-in file
layer is created.
- Clarify the `log_dir` config/schema text and `docs/install.md` example
so users opt in with `codex -c log_dir=...` when they need a plaintext
log.
## Why
Remote compaction v2 sends a normal `/responses` request with a
compaction trigger. It should follow the retry semantics used by normal
Responses streaming calls for transient stream/request failures, while
keeping a smaller per-transport retry budget because compact attempts
can run much longer than normal turns.
## What changed
- Add a v2 compaction retry loop that uses `stream_max_retries`,
matching normal Responses turn retry mechanics.
- Cap the compact v2 retry budget at 2 retries per transport with
`min(stream_max_retries, 2)`.
- Retry retryable request-open and post-open stream collection failures
through the same loop.
- Use the existing 200ms exponential backoff and requested retry delay
handling used by normal turn retries.
- Emit the same `Reconnecting... n/max` stream-error notification
pattern.
- Fall back from WebSockets to HTTPS after the compact v2 stream retry
budget is exhausted, then reset the retry counter for HTTPS.
- Keep final remote-compaction failure logging after retries/fallback
are exhausted.
- Treat compact stream EOF before `response.completed` as a retryable
stream failure.
- Add compact v2 regression coverage with `request_max_retries = 0` and
`stream_max_retries = 2`, covering both request-open failure and
opened-stream EOF in one end-to-end test.
## Tests
- `just fmt`
- `cargo test -p codex-core remote_compact_v2`
- `just fix -p codex-core`
`cargo test` for the core and other crates fails on a fresh macOS
checkout without the right stack size variable. This change encourages
using the just test command that sets the environment up correctly.
As a bonus, this should encourage agents to get more benefit out of
nextest's parallel execution.
`#[serde(default)]` wasn't sufficient for our generated TS types to
reflect that clients didn't have to set them. We also need
`skip_serializing_if = "std::ops::Not::not"`. This is already a rule in
our agents.md file.
Updates our build script to pull down the artifacts like we do in CI for
building v8 into our targets.
This changes the flow so that we now pre-install rusty v8 assets for all
of our release targets from pre-built in workflow.
Secondarily if running it locally we now optionally pull the assets down
on python run assuming the user hasn't set the proper values, it then
provides them.
Sorry for the miss here.
## Why
`--profile` now selects `<name>.config.toml`, so the legacy `profile`
selector should not be reintroduced through config write or MCP tool
paths. A matching legacy selector in base user config also needs the
same migration guard as a matching legacy `[profiles.<name>]` table so
profile loading fails with one clear migration error instead of mixing
the old and new profile models.
## What
- reject non-null app-server config writes to the top-level legacy
`profile` selector
- make `--profile <name>` reject base user config that still selects the
same legacy `profile = "<name>"` value, alongside the existing matching
legacy profile-table guard
- reject removed MCP `codex` tool fields such as `profile` by denying
unknown tool-call parameters and exposing that restriction in the
generated schema
- add regression coverage for the app-server write paths, config loader
guard, and MCP tool input/schema behavior
## Verification
- targeted regression tests cover the new app-server, config loader, and
MCP rejection paths
## Summary
- drop the dead legacy profile usage metric and active-profile
conversation-start fields
- update role comments so they describe provider and service-tier
preservation without legacy config-profile wording
- pair the code cleanup with the file-backed profile docs update in
openai/developers-website#1476
## Testing
- `just fmt`
- `cargo test -p codex-otel`
- `cargo test -p codex-core` *(fails: existing stack overflow in
`mcp_tool_call::tests::guardian_mode_mcp_denial_returns_rationale_message`)*
- `cargo test -p codex-core --lib
mcp_tool_call::tests::guardian_mode_mcp_denial_returns_rationale_message`
*(fails with the same stack overflow)*
## Why
`/feedback` asks `ThreadManager` for the selected agent subtree before
it uploads logs. The previous live subtree path reconstructed
parent-child links by iterating every loaded thread and awaiting each
thread config snapshot, so unrelated loaded-thread state could stall
feedback subtree enumeration.
The loaded-thread set already belongs to
[`ThreadManagerState`](50e6644c94/codex-rs/core/src/thread_manager.rs).
Reading thread-spawn parents from the captured `CodexThread` session
sources at that boundary keeps unload and resume behavior manager-owned
while avoiding per-session config inspection.
## What Changed
- expose parent-child thread-spawn edges for loaded, non-internal
threads from `ThreadManagerState`
- build the live child map from those edges while keeping agent metadata
lookup and ordering in `AgentControl`
- add regression coverage for live subtree enumeration when no state DB
is available
## Validation
- `git diff --check`
- local Rust tests not run per request
## Why
[#23883](https://github.com/openai/codex/pull/23883) moved the
user-facing `--profile` flag onto profile v2 and
[#23886](https://github.com/openai/codex/pull/23886) removed CLI
forwarding for the legacy profile-v1 path. Core and TUI config
persistence still carried `active_profile` and
`ConfigEditsBuilder::with_profile`, which let later writes continue
targeting legacy `[profiles.<name>]` tables after profile selection
moved to profile-v2 config files.
## What
- Remove legacy profile routing from
[`ConfigEditsBuilder`](4b38e9c22e/codex-rs/core/src/config/edit.rs (L1064-L1294)),
so core config edits no longer carry `with_profile` or infer
`[profiles.*]` write targets from a `profile` key.
- Drop `active_profile` plumbing from runtime `Config`, TUI
startup/state, app-server config override forwarding, and Windows
sandbox setup persistence.
- Make app-server-backed TUI config edits use unscoped model,
service-tier, feature, Auto-review, plan-mode, and Windows sandbox paths
through
[`tui/src/config_update.rs`](4b38e9c22e/codex-rs/tui/src/config_update.rs (L43-L112)).
- Update config edit coverage so legacy `profile` state stays untouched
by direct model writes, and remove tests whose only contract was the
deleted profile-scoped persistence path.
## Testing
- Not run locally.
## Why
[#23883](https://github.com/openai/codex/pull/23883) moved user-facing
`--profile` selection onto profile v2, and
[#23886](https://github.com/openai/codex/pull/23886) removed the old CLI
`config_profile` override path. Core still had a second legacy path:
`profile = "..."` could select `[profiles.*]` values while runtime
config was built. Keeping that resolver alive preserves the old
precedence model and profile-carrying surfaces even though profile
selection now points at `$CODEX_HOME/<name>.config.toml`.
## What
- Reject legacy top-level `profile = "..."` config while loading runtime
config, with an error that points callers at `--profile <name>` and
`<name>.config.toml` in the [core load
path](3d923366ec/codex-rs/core/src/config/mod.rs (L2524-L2531)).
- Remove the remaining profile-v1 merge points from runtime config
resolution, including features, permissions, model/provider selection,
web search, Windows sandbox settings, TUI settings, role reloads, and
OSS provider lookup.
- Drop the leftover profile override surface from
[`ConfigOverrides`](3d923366ec/codex-rs/core/src/config/mod.rs (L2118-L2148))
and from the MCP server `codex` tool schema.
- Prune profile-precedence tests that only exercised the removed
resolver and replace them with rejection coverage for the legacy
selector.
## Testing
- Not run in this metadata pass.
- Added
[`legacy_profile_selection_is_rejected`](3d923366ec/codex-rs/core/src/config/config_tests.rs (L7942-L7965))
coverage for the new runtime guard.
## Why
`codex --profile <name> mcp ...` should reach the same profile-v2
migration guard as runtime commands. Otherwise legacy
`[profiles.<name>]` users see the generic command-scope rejection
instead of the existing guidance to move settings into
`$CODEX_HOME/<name>.config.toml`.
## What
- Allow `codex mcp` through the `--profile` subcommand gate.
- Pass profile loader overrides into the MCP entry point only to
validate profile-v2 migration when a profile is present.
- Keep MCP add/remove/list/get/login/logout behavior otherwise
unchanged; this does not add profile-scoped MCP server management.
- Cover the legacy profile migration error for `codex --profile work mcp
list`.
## Testing
- `cargo test -p codex-cli`
## Summary
- set `NODE_USE_ENV_PROXY=1` when Codex applies managed network proxy
environment overrides
- keep the Node opt-in in the proxy environment key set used by
shell/runtime env handling
- cover the new env var in the focused network proxy env test
## Why
Codex already sets HTTP proxy environment variables for child processes
when the managed network proxy is active. Node's built-in network
behavior needs the `NODE_USE_ENV_PROXY` opt-in to honor those env vars,
so Node-based skill scripts can otherwise skip the managed proxy path
and fail under restricted network access.
## Validation
- `just fmt` in `codex-rs`
- `cargo test -p codex-network-proxy` in `codex-rs`
## Summary
- Treat MCP tools with `readOnlyHint: true` as parallel-safe even when
`supports_parallel_tool_calls` is unset or `false`.
- Keep server-level `supports_parallel_tool_calls` as an additive
override for non-read-only tools.
- Add focused unit coverage for the MCP handler eligibility decision.
- Update RMCP integration coverage to keep the serial baseline on a
mutable tool, verify read-only concurrency without server opt-in, and
preserve the server opt-in concurrency path separately.
## Testing
- `just fmt`
- `cargo test -p codex-core --lib tools::handlers::mcp::tests::`
- `cargo test -p codex-core --test all
stdio_mcp_read_only_tool_calls_run_concurrently_without_server_opt_in`
- `cargo test -p codex-core --test all
stdio_mcp_parallel_tool_calls_opt_in_runs_concurrently`
- `cargo test -p codex-rmcp-client`
## Why
The `dev/cc/ref-def` branch preserves richer JSON Schema detail for
connector tools, including `$defs` and nested shapes. That improves
fidelity, but it pushes the largest connector schemas well past the
intended tool-schema budget. This PR adds a best-effort compaction pass
for unusually large tool input schemas so the p99 and max tails stay
small while ordinary schemas are left alone.
## What Changed
- Added best-effort large-schema compaction in
`codex-rs/tools/src/json_schema.rs` after schema sanitization and
definition pruning.
- Compaction runs as a waterfall only while the compact JSON budget
proxy is exceeded:
1. Strip schema `description` metadata.
2. Drop root `$defs` / `definitions`.
3. Collapse deep nested complex schema objects to `{}`.
- Kept top-level argument names and immediate schema shape where
possible.
## Corpus Results
Scope: 2,025 schemas under `golden_schemas`, all parsed successfully.
Token count is `o200k_base` over compact JSON from
`parse_tool_input_schema`.

### Compaction Savings
These are cumulative waterfall stages over the same corpus. Later passes
only run for schemas that are still over the compact JSON budget proxy.

## Why
Extension tools that need conversation context should be able to read it
from the live tool invocation instead of reaching into thread
persistence themselves.
## What changed
- Add a `ConversationHistory` snapshot to extension `ToolCall`s and
populate it from the current raw in-memory response history.
- Expose all history items at this boundary so each extension can filter
and bound the subset it needs before consuming or forwarding it.
- Cover the adapter and registry dispatch paths and update existing
extension tests that construct `ToolCall` literals.
## Test plan
- `cargo test -p codex-tools`
- `cargo test -p codex-extension-api`
- `cargo test -p codex-goal-extension`
- `cargo test -p codex-memories-extension`
- `cargo test -p codex-core passes_turn_fields_to_extension_call`
- `cargo test -p codex-core
extension_tool_executors_are_model_visible_and_dispatchable`
# Why
Some connector tool input schemas use local JSON Schema references and
definition tables to avoid duplicating large nested shapes. Codex
previously lowered these schemas into the supported subset in a way that
could discard `$ref`-only schema objects and lose the corresponding
definitions, which made non-strict tool registration less faithful than
the original connector schema.
This keeps the existing minimal-lowering policy: Codex still does not
raw-pass through arbitrary JSON Schema, but it now preserves local
reference structure that fits the Responses-compatible subset and prunes
definition entries that cannot be reached by following `$ref`s from the
root schema after sanitization, including refs found transitively inside
other reachable definitions. The pruning matters because Responses
parses definition tables even when entries are unused, so keeping dead
definitions wastes prompt tokens.
# What changed
- Added `$ref`, `$defs`, and legacy `definitions` fields to the tool
`JsonSchema` representation.
- Updated `parse_tool_input_schema` lowering so `$ref`-only schema
objects survive sanitization instead of becoming `{}`.
- Sanitized definition tables recursively and dropped malformed
definition tables so non-strict registration degrades gracefully.
- Added reachability pruning for root definition tables by starting from
refs outside definition tables, then following refs inside reachable
definitions.
- Added JSON Pointer decoding for local definition refs such as
`#/$defs/Foo~1Bar`.
# Verification
ran local golden-schema probes against representative connector schemas
to validate behavior on real generated schemas:
| Golden schema | Before bytes | After bytes | `$defs` before -> after |
`$ref` before -> after | Result |
|---|---:|---:|---:|---:|---|
| `google_calendar/create_space` | 7111 | 4526 | 7 -> 7 | 7 -> 7 | all
definitions preserved because all are reachable |
| `figma/apply_file_variable_changes` | 4609 | 999 | 8 -> 5 | 8 -> 5 |
unused defs pruned after unsupported `oneOf` shapes lower away |
| `snowflake/list_catalog_integrations` | 1380 | 404 | 3 -> 0 | 0 -> 0 |
all defs pruned because none are referenced |
| `dropbox/create_shared_link` | 8894 | 1836 | 14 -> 4 | 9 -> 4 | only
defs reachable from the root schema after sanitization are retained,
including transitively through other retained defs |
Token increase across golden schema due to this change:

## Summary
The auto-review runtime sync path was assigning a raw
`PermissionProfile` into `runtime_permission_profile_override`, whose
field now expects `RuntimePermissionProfileOverride`. That broke the TUI
Bazel build.
This changes the assignment to store
`RuntimePermissionProfileOverride::from_config(&self.config)`, matching
the other runtime override paths and preserving the active profile and
network metadata with the permission profile.
## Summary
- Add us-gov-west-1 to the Bedrock Mantle supported region list
- Cover the GovCloud endpoint URL in the existing base_url unit test
## Test
- cargo test -p codex-model-provider
## Why
Experimental feature toggles and memory settings can update several
related config values in one interaction. Keeping those writes local in
a remote TUI session is especially dangerous because the UI can diverge
from the app-server config while also leaving behind partially stale
supporting keys.
This is **[3 of 4]** in a stacked series that moves TUI-owned config
mutations onto app-server APIs.
## What changed
- Routed feature flag persistence through app-server batch writes,
including the supporting reviewer and permission updates used by
guardian approval.
- Routed Windows sandbox mode persistence and legacy Windows feature
cleanup through app-server writes.
- Routed memory settings through app-server batch writes and updated the
TUI tests to exercise the embedded app-server path.
## Config keys affected
- `features.<feature_key>`
- `profiles.<profile>.features.<feature_key>`
- `approval_policy`
- `sandbox_mode`
- `approvals_reviewer`
- `windows.sandbox`
- `features.experimental_windows_sandbox`
- `features.elevated_windows_sandbox`
- `features.enable_experimental_windows_sandbox`
- Profile-scoped Windows legacy feature variants under
`profiles.<profile>.features.*`
- `memories.use_memories`
- `memories.generate_memories`
- Profile-scoped memory variants under `profiles.<profile>.memories.*`
## Suggested manual validation
- Connect the TUI to a remote app server, toggle guardian approval on
and off, and confirm the remote config updates
`features.guardian_approval`, reviewer state, approval policy, and
sandbox mode coherently.
- Toggle a default-false experimental feature at the root level, disable
it again, and confirm the key clears instead of lingering as an
unnecessary explicit `false`.
- Change memory settings and confirm the remote config updates both
memory keys while the running TUI reflects the new state.
- On Windows, switch sandbox mode through the TUI and confirm
`windows.sandbox` is updated while the legacy Windows feature keys are
cleared.

# What
When a normal hook fires inside a thread-spawned subagent, Codex now
includes these optional top-level fields in the hook input:
- `agent_id`: the child thread id
- `agent_type`: the subagent role
Root-agent hook inputs omit these fields. `SubagentStart` and
`SubagentStop` keep their existing required `agent_id` and `agent_type`
fields because those events are inherently subagent-scoped.
This does not change matcher behavior. Tool hooks still match on tool
name, compact hooks still match on trigger, and `UserPromptSubmit` still
ignores matchers. Only `SubagentStart` and `SubagentStop` match on
`agent_type`.
## Why
When remote control hits an auth failure such as a revoked or reused
refresh token, the websocket loop falls into reconnect backoff. If the
user fixes auth while that loop is sleeping, remote control can stay
offline until the old retry timer expires because nothing wakes the loop
or resets its exhausted auth recovery state.
## What Changed
Added an auth-change watch on `AuthManager` for refresh-relevant cached
auth updates.
The remote-control websocket loop now subscribes to that signal, resets
`UnauthorizedRecovery` and reconnect backoff when auth changes, and
retries immediately instead of waiting for the previous delay.
Updated the remote-control transport test to verify that reloading auth
with the now-available account id wakes enrollment before the prior
retry delay.
## Verification
`cargo test -p codex-app-server-transport
remote_control_waits_for_account_id_before_enrolling`
## Summary
- make rollout content search prefilter rollout files case-insensitively
- keep the no-ripgrep fallback scan and visible snippet matcher aligned
with that behavior
- cover a lowercase `thread/search` query matching mixed-case
conversation content
## Why
The rollout-backed `thread/search` path used exact string matching in
both its `rg` prefilter and semantic snippet generation. A content
result could be missed solely because the query casing did not match the
stored conversation text.
## Validation
- `just fmt`
- `cargo test -p codex-app-server thread_search_returns_content_matches`
- `cargo test -p codex-rollout`
- `just bazel-lock-update`
- `just bazel-lock-check`
- `cargo build -p codex-cli`
- launched a local Electron dev instance with the rebuilt CLI binary
## Why
`rust-release` now publishes `codex-package-<target>.tar.gz` as the
canonical native package payload. npm staging should consume those
archives directly instead of keeping legacy synthesis code that fetched
`rg`, copied standalone binaries, and rebuilt an approximate package
layout.
That also means the package builder should not know the internal shape
of `codex-package`. It should extract and copy the target payload
wholesale so future layout changes stay localized to the archive
producer.
The release job stages `codex`, `codex-responses-api-proxy`, and
`codex-sdk` together, so native artifact download should be filtered,
observable, and shared across component installs. Since that native
hydration is now only used by release staging, keeping a separate
`install_native_deps.py` CLI adds an extra wrapper without a real
caller.
## What Changed
- Removed legacy `codex-package` synthesis and related compatibility
flags from npm staging.
- Folded the remaining native artifact hydration code into
`scripts/stage_npm_packages.py` and deleted
`codex-cli/scripts/install_native_deps.py`.
- Made platform package staging copy the full extracted target directory
instead of enumerating package entries.
- Kept non-`codex-package` native components under their component
directory name instead of using a legacy destination map.
- Split native staging by component set while sharing one
workflow-artifact cache across the invocation.
- Changed workflow artifact download to select target artifacts by name,
print sizes/progress, and reuse cached artifacts.
- Removed the implicit `CI=true` default from `build_npm_package.py`;
local CI-shaped runs should set that environment explicitly.
- Kept `npm pack` cache/log output in its temporary directory so packing
does not write to the user npm cache.
## Verification
- `python3 -m py_compile scripts/stage_npm_packages.py
codex-cli/scripts/build_npm_package.py`
- `python3 -m unittest discover -s scripts/codex_package -p "test_*.py"`
- `scripts/stage_npm_packages.py --help`
- `codex-cli/scripts/build_npm_package.py --help`
- Ran the release-shaped staging command from `rust-release.yml` against
workflow run https://github.com/openai/codex/actions/runs/26240748758
with `CI=true` set locally to match GitHub Actions:
```sh
CI=true python3 ./scripts/stage_npm_packages.py \
--release-version 0.133.0 \
--workflow-url https://github.com/openai/codex/actions/runs/26240748758 \
--package codex \
--package codex-responses-api-proxy \
--package codex-sdk
```
That completed successfully, downloaded only the six target artifacts
once, reused the cache for `codex-responses-api-proxy`, and produced all
nine npm tarballs. Generated tarballs and staging/artifact temp dirs
were cleaned afterward.
# Why
This is a follow-up stacked on top of the `plugin_hooks` default-on
change. Once we are comfortable making plugin hooks part of the normal
plugin behavior, the separate feature flag stops buying us much and
leaves extra branching/cache state behind.
# What
- remove the `PluginHooks` feature and generated config-schema entries
- make plugin hook loading/listing follow plugin enablement directly
- drop plugin-manager cache/state that only existed to distinguish
hook-flag toggles
- remove tests and fixtures that modeled `plugin_hooks = true/false`
## Summary
- add experimental `thread/search` for local rollout-backed thread
search using `rg` over JSONL rollouts
- return search-specific result rows with optional previews instead of
storing preview data on `StoredThread` or ordinary `Thread` responses
- keep `thread/list` separate from full-content search and document the
new app-server surface
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server
thread_search_returns_content_and_title_matches -- --nocapture`
## Why
Users reported that the replacement confirmation feels unnecessary when
the current thread goal is already complete. In that state, `/goal
<objective>` is starting fresh rather than interrupting active work.
## What changed
`/goal <objective>` now skips the replace confirmation when the existing
goal has `complete` status and uses the existing fresh replacement path.
Goals that are active, paused, blocked, usage-limited, or budget-limited
still require confirmation before being replaced.
## Summary
- replace the one-shot lazy remote exec-server cache with a
lock-protected current client
- when the cached websocket client is already disconnected, create one
fresh websocket client/session on the next `get()`
- keep existing disconnect failure behavior for old process sessions and
HTTP body streams; do not add session resume or request retry
## Why
The prior PR direction was trying to grow into session restore: resume
the old `session_id`, preserve existing process handles, and add
reconnect retry policy. That is more machinery than we want for this
slice.
For now, the useful minimum is simpler: later fresh remote operations
should not be stuck behind a dead cached websocket client, but anything
already attached to the dead connection should fail loudly through the
existing disconnect path. The server already has detached-session
cleanup via its existing TTL, so this PR does not need to add
client-side session preservation.
## What Changed
- `LazyRemoteExecServerClient::get()` now keeps the current concrete
client in a small mutex-protected cache plus one async connect lock.
- If that cached client is still connected, `get()` returns it.
- If that cached websocket client has observed the transport close,
`get()` creates a brand-new websocket client with a brand-new
exec-server session and replaces the cache.
- If that cached client is stdio-backed, behavior stays one-shot: the
dead client is returned and later work surfaces the existing disconnect
error.
- No `resume_session_id`, backoff, request replay, or existing
`RemoteExecProcess` rebinding is added here.
- Added focused websocket coverage that proves two concurrent `get()`
calls after disconnect share one fresh replacement client/session.
## Why
When a user runs `/goal` in a temporary session, the TUI can currently
surface an internal app-server failure such as `thread/goal/get failed
in TUI`. That message is technically true, but it does not explain the
actual constraint: goals require a saved session because goal state is
persisted with the thread.
This is especially confusing when `codex doctor` reports the background
app-server as running in ephemeral mode, since that wording is easy to
conflate with ephemeral thread/session behavior.
## What changed
- Added a TUI-side formatter for thread-goal RPC failures in
`codex-rs/tui/src/app/thread_goal_actions.rs`.
- Detects app-server/core errors that indicate goals are unsupported for
an ephemeral thread/session.
- Replaces the internal RPC failure with a user-facing explanation:
```text
Goals need a saved session. This session is temporary.
Run `codex` to start a saved session, or `codex resume` / `/resume` to reopen one.
```
- Preserves the existing generic failure wording for non-ephemeral goal
errors.
## Verification
- `cargo test -p codex-tui thread_goal_error_message --lib`
I also tried `cargo test -p codex-tui`; it built successfully but the
test runner aborted in an unrelated side-thread stack overflow
(`app::tests::discard_side_thread_removes_agent_navigation_entry`),
which reproduced when run by itself.
## Why
Installing `@openai/codex` currently places a Dotslash `rg` manifest at
`node_modules/@openai/codex/bin/rg`, even though the native optional
dependency already ships the actual helper under
`vendor/<target>/codex-path/rg`. The launcher prepends that `codex-path`
directory, so the top-level `bin/rg` file is redundant in the npm
install.
The remaining direct consumers of the manifest are package-building
paths: `scripts/codex_package/ripgrep.py` and
`codex-cli/scripts/install_native_deps.py`. Keeping the manifest under
`codex-cli/bin` makes it look like a shipped npm binary, so this moves
it next to the package-builder code that owns it. The checked-in
`@openai/codex` package metadata should likewise describe only the meta
package payload; generated platform packages continue to publish
`vendor`.
## What Changed
- Moved the Dotslash ripgrep manifest from `codex-cli/bin/rg` to
`scripts/codex_package/rg`.
- Updated the package builder, npm native-artifact hydrator, README, and
CLI help text to reference the new manifest location.
- Stopped `codex-cli/scripts/build_npm_package.py` from copying `rg`
into the `@openai/codex` meta package.
- Narrowed the checked-in meta package `files` whitelist to
`bin/codex.js`.
## Verification
- `python3 -m unittest discover -s scripts/codex_package -p "test_*.py"`
- `python3 -m unittest discover -s codex-cli/scripts -p "test_*.py"`
- `python3 -m py_compile codex-cli/scripts/build_npm_package.py
codex-cli/scripts/install_native_deps.py
scripts/codex_package/ripgrep.py scripts/codex_package/cli.py
scripts/stage_npm_packages.py`
- `codex-cli/scripts/build_npm_package.py --package codex --version
0.0.0-test --pack-output <tmp>/codex-meta-no-vendor.tgz`
- `tar -tf <tmp>/codex-meta-no-vendor.tgz` showed only
`package/bin/codex.js`, `package/package.json`, and `package/README.md`.
- Direct staging check showed `codex` uses `files: ["bin/codex.js"]`
while `codex-darwin-arm64` still uses `files: ["vendor"]`.

## Why
The named-profile `/permissions` picker needs a small TUI action path
that can select permission profiles without folding the menu UI and
profile metadata into the same review.
## What changed
- Carry permission-profile selections through the TUI app event flow.
- Persist selected profiles while preserving the existing approval
settings and guardrail prompts.
- Keep the legacy `/permissions` picker behavior in this layer; the
profile-mode menu stays in the follow-up PR.
## Stack
1. [#22931](https://github.com/openai/codex/pull/22931):
runtime/session/network propagation for active permission profiles.
2. **This PR**: TUI selection plumbing and guardrail flow.
3. [#21559](https://github.com/openai/codex/pull/21559): profile-aware
`/permissions` menu and custom profile display.

/>
## Validation
- `git diff --cached --check` before commit.
- Full test run skipped at the user request while pushing the split
stack.
## Why
[#23883](https://github.com/openai/codex/pull/23883) moved the
user-facing `--profile` flag onto profile v2. The shared CLI option
layer still carried the old `config_profile` slot and several CLI
entrypoints still copied that value into legacy config overrides.
Leaving that path around makes the CLI surface look like it still
selects legacy `[profiles.*]` state even though `--profile` now means
`$CODEX_HOME/<name>.config.toml`.
## What
- Remove the legacy `config_profile` field and merge/copy path from
[`SharedCliOptions`](95baaf7292/codex-rs/utils/cli/src/shared_options.rs (L8-L177)).
- Stop forwarding profile-v1 overrides from CLI, exec, TUI, doctor,
debug, feature, and exec-server paths; runtime profile selection remains
on `config_profile_v2` through
[`loader_overrides_for_profile`](95baaf7292/codex-rs/cli/src/main.rs (L1606-L1619)).
- Resolve local OSS provider selection from the base config in exec and
TUI now that the legacy profile argument is gone.
## Testing
- Not run (cleanup-only follow-up to #23883).
## Summary
- route each configured MCP server through an explicit per-server
`environment_id` instead of a manager-wide remote toggle
- default omitted `environment_id` to `local`, resolve named ids through
`EnvironmentManager`, and fail only the affected MCP server when an
explicit id is unknown
- keep local stdio on the existing local launcher path for now, while
named-environment stdio uses the selected environment backend and
requires an absolute `cwd`
- allow local HTTP MCP servers to keep using the ambient HTTP client
when no local `Environment` is configured; named-environment HTTP MCPs
use that environment's HTTP client
## Validation
- devbox Bazel build: `bazel build --bes_backend= --bes_results_url=
//codex-rs/cli:codex //codex-rs/rmcp-client:test_stdio_server
//codex-rs/rmcp-client:test_streamable_http_server`
- devbox app-server config matrix with real `config.toml` /
`environments.toml` files covering omitted local, explicit local,
omitted local under remote default, explicit remote stdio, local HTTP
without local env, explicit remote HTTP, local stdio without local env,
unknown explicit env, and remote stdio without `cwd`
## Why
Profile v2 is taking over the user-facing profile selection path, so the
CLI no longer needs to expose the transitional `--profile-v2` spelling.
This switches the public args surface to `--profile` before the
remaining legacy profile plumbing is removed separately.
## What
- Rebind `--profile` and `-p` to the v2 profile name argument that
selects `$CODEX_HOME/<name>.config.toml`.
- Stop parsing the legacy shared CLI profile argument while keeping its
implementation path in place for follow-up cleanup.
- Update CLI validation, profile-name parse errors, and the
legacy-profile collision message/tests to refer to `--profile`.
## Testing
- `cargo test -p codex-cli -p codex-config -p codex-protocol -p
codex-utils-cli`
## Why
Tool exposure is a planning concern, but the deferred MCP path and
dispatch-only legacy shell path were carrying those decisions in handler
constructors and a shell-only tool-family builder. Keeping those
decisions in `spec_plan` makes the core tool plan easier to follow and
keeps handlers focused on runtime behavior.
## What changed
- add `PlannedTools` helpers for ordinary runtimes, exposure overrides,
dispatch-only runtimes, and hosted specs
- inline shell tool assembly into `core/src/tools/spec_plan.rs` and
remove the shell-only `tool_family` module
- remove exposure state and special exposure constructors from
`McpHandler` and `ShellCommandHandler`
- keep hidden runtime behavior centralized in `ExposureOverride`,
including disabling parallel tool calls for hidden handlers
## Testing
- Not run (refactor only)
## What
Remove the exact captured request-count assertion from the
`SubagentStart` hook integration test while still waiting for the child
request that matches the injected hook context.
## Why
The test owns the start-hook behavior and already verifies that the
child request reaches the context matcher plus that the start/session
hook logs have the expected invocations. Counting every request captured
by the response mock makes the test sensitive to lifecycle timing
outside that contract and has been flaky in CI.
## Testing
- `cargo test -p codex-core --test all
suite::subagent_notifications::subagent_start_replaces_session_start_and_injects_context
-- --exact`
## Why
`ToolExecutor` is the runtime contract that keeps a callable tool and
its model-visible spec together. Leaving `spec()` optional lets a
registered runtime silently omit that half of the contract, and it also
overloads a missing spec as an exposure decision for tools that should
stay dispatchable without being shown to the model.
## What
- Make `ToolExecutor::spec()` required and update core, extension, and
test tool executors to return a concrete `ToolSpec`.
- Add `ToolExposure::Hidden` for dispatch-only tools. The legacy
`shell_command` runtime in unified-exec sessions now uses that explicit
exposure instead of hiding itself by omitting a spec.
- Build MCP tool specs when `McpHandler` is constructed so invalid MCP
specs are skipped before the handler is registered.
- Keep tool planning aligned with the new contract for direct, deferred,
hidden, code-mode, dynamic, and namespaced tool paths.
## Testing
- Added tool-plan coverage that invalid MCP tool specs are not
registered.
- Updated shell-family coverage for the hidden legacy `shell_command`
runtime and the affected tool executor test fixtures.
## Why
Remote compaction now has two implementations: the existing
server-rebuilt v1 path and the newer client-rebuilt v2 path behind
`remote_compaction_v2`. The v1 path bounds retained
user/developer/system history before installing the compaction item,
while v2 was previously carrying the full retained history forward. That
made the two paths diverge for large pre-compaction transcripts even
though they are meant to preserve the same compaction contract.
This aligns v2 with the retained-history budget expected from v1 so
switching the feature flag does not materially change which
pre-compaction messages survive into the rebuilt history.
## What changed
- Apply a retained-message character budget while rebuilding v2
compacted history in `core/src/compact_remote_v2.rs`.
- Keep newest retained messages first, truncate the boundary message
with the shared `truncate_text(...)` helper, and drop older retained
messages once the budget is exhausted.
- Preserve non-text retained message content such as images while
truncating text content.
- Use the current `64_000` token retained-message default translated to
the existing `4x` character budget.
## Testing
- `cargo test -p codex-core compact_remote_v2::tests::`
- Added focused coverage for newest-first retention and truncating
multipart retained messages without dropping images.
## What
- Add a small extension capability for injecting model-visible response
items into the active turn
- Have the goal extension inject hidden goal-context steering when
tool-finish accounting reaches `BudgetLimited`
- Cover the extension backend path with an assertion on the injected
steering item
## Why
PR #23696 persists and emits the budget-limited goal update from
tool-finish accounting, but it leaves the model unaware of that
transition. The existing core runtime steers the model to wrap up in
this case; the extension path should do the same through an explicit
host capability.
## Testing
- `just fmt`
- `cargo test -p codex-goal-extension`
- `cargo test -p codex-extension-api`
## Why
`prewarm_websocket` intentionally stays out of rollout inference
tracing, but the next traced websocket request can still reuse the
warmup `response_id` and send an empty `input` delta. If tracing records
that wire payload verbatim, replay sees an incremental request whose
parent was never traced and cannot reconstruct the conversation.
This fixes that at the producer boundary instead of relaxing
`rollout-trace` replay semantics around unresolved
`previous_response_id` values.
## What
- track whether the last websocket response came from an untraced warmup
and clear that state when the websocket session is reset or reconnected
- when a traced websocket request reuses that warmup parent, keep
sending the compressed websocket request on the wire but record the
logical `ResponsesApiRequest` in the rollout trace
- add a regression test that proves replay reconstructs the logical user
message even though the websocket follow-up carries
`previous_response_id = warm-1` with empty `input`
- update `InferenceTraceAttempt::record_started` docs to reflect that
callers may record a logical request rather than the exact transport
payload
## Testing
- `cargo test -p codex-core --test all
responses_websocket_request_prewarm_traces_logical_request`
## Why
The Python and TypeScript SDKs launch the native Codex runtime directly,
so they need to consume the same package artifact shape that release
jobs now produce. The runtime wheel should be built from the canonical
Codex package archive rather than reconstructing a parallel layout from
loose binaries.
## What Changed
- Stage `openai-codex-cli-bin` by extracting
`codex-package-<target>.tar.gz` into `src/codex_cli_bin` and validating
the expected package layout.
- Update release workflows to pass the generated package archive into
`stage-runtime` instead of the temporary package directory.
- Update Python runtime setup to download `codex-package-*.tar.gz`
release assets directly.
- Expose Python runtime helpers for the bundled package directory and
`codex-path`, and prepend that path when `openai_codex` launches the
installed runtime without duplicating Windows `Path`/`PATH` keys.
- Teach the TypeScript SDK to resolve package-layout optional
dependencies while keeping the existing npm fallback layout, and
preserve the existing Windows path variable casing when prepending
`codex-path`.
## Test Plan
- `python3 -m py_compile sdk/python/scripts/update_sdk_artifacts.py
sdk/python/_runtime_setup.py sdk/python/src/openai_codex/client.py
sdk/python-runtime/src/codex_cli_bin/__init__.py`

- `uv run --frozen --project sdk/python --extra dev pytest

- `pnpm eslint src/exec.ts tests/exec.test.ts`
- `pnpm test --runInBand tests/exec.test.ts`
## Why
This is the functional handoff PR for the Windows sandbox
`PermissionProfile` migration. After #23714, the Windows elevated
backend can accept a profile-native request, but core still sent a
compatibility `SandboxPolicy` into the elevated command-runner path.
That meant profile-only details such as deny globs had to be translated
through side channels instead of being preserved in the runner
`SpawnRequest`.
Passing the real `PermissionProfile` completes the command-runner
handoff while leaving the unelevated restricted-token fallback on the
legacy policy-string API.
## What
- Updates one-shot Windows elevated execution in `core/src/exec.rs` to
call `run_windows_sandbox_capture_for_permission_profile_elevated`.
- Updates unified exec in `core/src/unified_exec/process_manager.rs` to
call `spawn_windows_sandbox_session_elevated_for_permission_profile`.
- Passes `request.permission_profile` /
`exec_request.permission_profile` and the stored Windows sandbox policy
cwd to the elevated backend.
- Keeps compatibility `SandboxPolicy` serialization only for the
non-elevated restricted-token fallback.
## Verification
- `cargo test -p codex-core --test all --no-run`
## Why
Cloud-managed `requirements.toml` should be able to define the managed
permission profiles a client may select and constrain that selectable
set without requiring local user config to recreate the profile catalog.
This keeps requirements focused on restrictions. The selected default
remains a config or session choice, while requirements contribute the
managed profile bodies and `allowed_permissions` allowlist that the
config-loading boundary validates before a resolved runtime
`PermissionProfile` is installed.
## What changed
- Add `requirements.toml` support for a managed permission-profile
catalog plus its allowlist:
```toml
allowed_permissions = ["review", "build"]
[permissions.review]
extends = ":read-only"
[permissions.build]
extends = ":workspace"
```
- Merge requirements-defined profile bodies into the effective
permission catalog and reject profile ids that collide with
config-defined profiles.
- Validate that every `allowed_permissions` entry resolves to a built-in
or catalog profile before selection uses it.
- Preserve allowed configured named-profile selections. When a
configured named profile is disallowed, fall back to the first allowed
requirements profile with a startup warning.
- Keep built-in selections and the stock trust-based `:read-only` /
`:workspace` fallback path intact when no permission profile is
explicitly selected.
- Centralize the managed catalog and allowlist selection path in
`EffectivePermissionSelection` so the requirements boundary is visible
in config loading.
- Surface `allowedPermissions` through `configRequirements/read`, and
update the generated app-server schema fixtures plus the app-server
README.
## Validation
- `cargo test -p codex-config`
- `cargo test -p codex-core system_requirements_`
- `cargo test -p codex-core system_allowed_permissions_`
- `cargo test -p codex-app-server-protocol`
- `just write-app-server-schema`
## Related work
- Uses merged permission-profile inheritance support from #22270 and
#23705.
- Kept separate from the in-flight permission profile listing API in
#23412.
## Why
This is the next step after #23167 in the Windows sandbox
`PermissionProfile` migration. The elevated Windows backend still
exposed policy-string entry points, which forced callers to pass a
compatibility `SandboxPolicy` before the command-runner IPC could
receive a profile.
Adding profile-native APIs first keeps the core switch in the next PR
small: reviewers can see that the Windows crate can prepare elevated
setup, capability SIDs, and runner IPC from a resolved
`PermissionProfile` without changing core behavior yet.
## What
- Adds `ElevatedSandboxProfileCaptureRequest` and
`run_windows_sandbox_capture_for_permission_profile_elevated` for
one-shot elevated capture.
- Adds `spawn_windows_sandbox_session_elevated_for_permission_profile`
for unified exec sessions.
- Factors elevated spawn prep through
`prepare_elevated_spawn_context_for_permissions`, so both new APIs
operate from `ResolvedWindowsSandboxPermissions` directly.
- Keeps the existing legacy policy-string APIs as adapters for callers
that have not moved yet.
## Verification
- `cargo test -p codex-windows-sandbox`

* #23715
* __->__ #23714
## Why
If a user configures `approval_policy = "never"` with `sandbox_mode =
"danger-full-access"`, managed requirements can reject full access and
force the existing permission fallback to read-only. That leaves Codex
in a dead-end session: writes are blocked by the sandbox, while
approvals are disabled so the session cannot ask to proceed.
This PR rejects that constrained configuration during startup instead of
letting the TUI enter a read-only session that cannot make progress. The
rejection is attached to the requirement-constrained permission path in
[`Config`](39f0abc0a7/codex-rs/core/src/config/mod.rs (L3301-L3318)).
## What changed
- Reject the `danger-full-access` to read-only managed-requirements
fallback when the effective approval policy is `never`.
- Explain in the startup config error why the fallback is invalid and
how to fix it.
- Add a regression test for the managed requirements path.
