## Why
`model_auto_compact_token_limit` has only been able to budget the full
active context. That makes it hard to set a small "growth since
compaction" budget for sessions that preserve a large carried window
prefix: the preserved prefix can consume the whole budget and force
immediate repeated compaction.
This PR adds an opt-in `body_after_prefix` scope so callers can apply
`model_auto_compact_token_limit` to sampled output and later growth
after the current carried prefix, while still forcing compaction before
the full model context window is exhausted.
## What changed
- Adds `AutoCompactTokenLimitScope` with the existing `total` behavior
as the default and a new `body_after_prefix` mode:
[`config_types.rs`](973806b1cb/codex-rs/protocol/src/config_types.rs (L24-L37)).
- Threads `model_auto_compact_token_limit_scope` through config loading,
`Config`, `core-api`, and app-server v2 schema/TypeScript generation.
- Records the first observed input-token count for a `body_after_prefix`
compaction window and uses it as the baseline when deciding whether the
scoped auto-compaction budget is exhausted:
[`turn.rs`](973806b1cb/codex-rs/core/src/session/turn.rs (L743-L781)).
- Keeps a hard context-window cap in `body_after_prefix`, so scoped
budgeting cannot let the active context overrun the usable window.
## Verification
Added compact-suite coverage for the two key behaviors:
`body_after_prefix` does not re-compact just because the carried prefix
is larger than the scoped budget, and it still compacts when the total
active context reaches the configured context window:
[`compact.rs`](973806b1cb/codex-rs/core/tests/suite/compact.rs (L3003-L3128)).
## Why
`codex-tools` is meant to hold reusable tool primitives, but
`ToolsConfig` had become a second copy of core runtime decisions instead
of a small shared contract. It carried provider capabilities, auth/model
gates, permission and environment state, web/search/image feature gates,
multi-agent settings, and goal availability from core into `codex-tools`
([definition](22dd9ad392/codex-rs/tools/src/tool_config.rs (L97)),
[stored on each
`TurnContext`](22dd9ad392/codex-rs/core/src/session/turn_context.rs (L87))).
Every session/context variant then had to build and mutate that snapshot
before assembling tools.
This PR removes that master object instead of renaming it. Tool planning
now reads the live `TurnContext`, where `codex-core` already owns those
decisions, while `codex-tools` keeps only reusable primitives and a
generic `ToolSetBuilder`/`ToolSet` accumulator.
## What Changed
- Removed `ToolsConfig` / `ToolsConfigParams` from `codex-tools`; the
crate keeps the shared helpers that still belong there, including
request-user-input mode selection, shell backend/type resolution,
`UnifiedExecShellMode`, and `ToolEnvironmentMode`.
- Replaced config-snapshot planning with `ToolRouter::from_turn_context`
and a `spec_plan` pipeline over `CoreToolPlanContext`, deriving provider
capabilities, auth gates, model support, feature gates, environment
count, goal support, multi-agent options, web search, and image
generation from the authoritative turn state.
- Added generic `codex_tools::ToolSetBuilder` / `ToolSet`, plus the
small core adapter needed to accumulate `CoreToolRuntime` values and
hosted model specs.
- Added the `tool_family::shell` registration module and moved
shell/unified-exec/memory accounting call sites to read the narrow
per-turn fields directly.
- Narrowed `TurnContext` to the remaining explicit per-turn fields
needed by planning: `available_models`, `unified_exec_shell_mode`, and
`goal_tools_supported`.
- Reworked MCP exposure and tool-search setup so deferred/direct MCP
behavior is driven by the current turn rather than a precomputed config
snapshot.
- Replaced the large expected-spec fixture tests with focused
behavior-level coverage for shell tools, environments, goal and
agent-job gates, MCP direct/deferred exposure, tool search,
request-plugin-install, code mode, multi-agent mode, hosted tools, and
extension executor dispatch.

## Why
Thread goals are moving toward extension-owned runtime behavior, but
their persisted state was still stored in the shared state database.
This makes the goal store harder to isolate and keeps future storage
splits tied to ad hoc runtime plumbing.
This PR gives goals their own SQLite database while keeping the existing
`StateRuntime` entry point. The goal is to make this the pattern for
adding more dedicated runtime databases later.
This also reduce load on existing DB and reduce contention
## Limitation
Thread preview from goal is not supported anymore. I'm looking into this
[EDIT]: solved
## What changed
- Added a dedicated `goals_1.sqlite` database with its own
`goals_migrations` directory.
- Moved `thread_goals` creation into the goals DB migration set.
- Dropped the old `thread_goals` table from the main state DB with a
normal state migration. There is intentionally no backfill for existing
goal rows.
- Changed `GoalStore` to be backed only by the goals DB pool.
- Removed the old goal-write side effect that filled empty
`threads.preview` values from the goal objective.
- Added shared runtime DB path metadata so startup, telemetry, `codex
doctor`, and repair handling can include future DBs without bespoke path
lists.
- Updated Bazel compile data so the new goals migration directory is
available to `sqlx::migrate!`.

## Why
Full-history agent forks should continue from the same prompt prefix as
the parent. Dropping the stored `TurnContext` baseline forced the child
to rebuild startup context on its first turn, which can duplicate
developer instructions and also loses the cache continuity that a
full-history fork is supposed to preserve.
Truncated forks are different: once we keep only the last N turns, the
original prompt prefix is no longer intact, so the child must establish
a fresh context baseline.
## What changed
- Preserve `RolloutItem::TurnContext` when forking with
`SpawnAgentForkMode::FullHistory`, and keep dropping it for truncated
forks:
4090717d94/codex-rs/core/src/agent/control.rs (L98-L126)
and
4090717d94/codex-rs/core/src/agent/control.rs (L399-L401)
- Remove the special-case MultiAgentV2 usage-hint filtering path.
Full-history fork now preserves the cached developer prefix instead of
trying to reconstruct part of it.
- Extend the fork coverage to assert both sides of the contract:
full-history forks keep the parent reference baseline, while last-N
forks rebuild context after truncation:
4090717d94/codex-rs/core/src/agent/control_tests.rs (L603-L759)
and
4090717d94/codex-rs/core/src/agent/control_tests.rs (L854-L977)

- `RUST_MIN_STACK=16777216 cargo test -p codex-core
spawn_agent_fork_last_n_turns_keeps_only_recent_turns -- --nocapture`
## Why
The `/permissions` picker needs a config-level way to distinguish legacy
anonymous presets from named permission-profile mode. That signal cannot
be inferred reliably in the TUI, especially for the edge case where
`default_permissions = ":workspace"` is present without a
`[permissions]` table.
## What changed
- Expose whether the merged config is explicitly in permission-profile
mode.
- Expose the configured custom permission profile IDs alongside the
built-in profile semantics.
- Add regression coverage for profile mode detection and custom profile
metadata, including the `default_permissions = ":workspace"` case.
- Update the thread-manager sample config literal to match the expanded
config shape.
## Stack

consumers.

## Summary
Move the rusty_v8 artifact production into hermetic Bazel path and bump
the `v8` crate to `147.4.0`
The new flow builds V8 release artifacts from source for Darwin and
Linux targets, publishes both the current release-compatible artifacts
and sandbox-enabled variants, and keeps Cargo consumers on prebuilt
binaries by continuing to feed the `v8` crate the archive and generated
binding files it already expects.
## Why
We need control over V8 build-time features without giving up prebuilt
artifacts for downstream Cargo builds.
Upstream `rusty_v8` already supports source-only features such as
`v8_enable_sandbox`, but its normal prebuilt release assets do not cover
every feature combination we need. Building the artifacts ourselves lets
us enable settings such as the V8 sandbox and pointer compression at
artifact build time, then publish those outputs so ordinary Cargo builds
can still consume prebuilts instead of compiling V8 locally.
This keeps the fast consumer experience of prebuilt `rusty_v8` archives
while giving us a reproducible path to ship featureful variants that
upstream does not currently publish for us.
## Implementation Notes
The Bazel graph in this PR is not copied wholesale from `rusty_v8`;
`rusty_v8`'s normal source build is still GN/Ninja-based.
Instead, this change starts from upstream V8's Bazel rules and adapts
them to Codex's hermetic toolchains and dependency layout. Where we
intentionally follow `rusty_v8`, we mirror its existing artifact
contract:
- the same `v8` crate version and generated binding expectations
- the same sandbox feature relationship, where sandboxing requires
pointer compression
- the same custom libc++ model expected by Cargo's default
`use_custom_libcxx` feature
- the same release-style archive plus `src_binding` outputs consumed by
the `v8` crate
To preserve that contract, the Bazel release path pins the libc++,
libc++abi, and llvm-libc revisions used by `rusty_v8 v147.4.0`, builds
release artifacts with `--config=rusty-v8-upstream-libcxx`, and folds
the matching runtime objects into the final static archive.
## Windows
Windows is annoyingly handled differently.
Codex's current hermetic Bazel Windows C++ platform is `windows-gnullvm`
/ `x86_64-w64-windows-gnu`, while upstream `rusty_v8` publishes Windows
prebuilts for `*-pc-windows-msvc`. Those are different ABIs, so the
Bazel graph cannot truthfully reproduce the upstream MSVC artifacts
until we add a real MSVC-targeting C++ toolchain.
For now:
- Windows MSVC consumers continue to use upstream `rusty_v8` release
archives.
- Windows GNU targets are built in-tree so they link against a matching
GNU ABI.
- The canary workflow separately exercises upstream `rusty_v8` source
builds for MSVC sandbox artifacts, but MSVC is not yet part of the
Bazel-produced release matrix.
## Validation
This PR is technically self validating through CI. I have already
published it as a release tag so the artifacts from this branch are
published to
https://github.com/openai/codex/releases/tag/rusty-v8-v147.4.0 CI for
this PR should therefore consume our own release targets. I have also
locally tested for linux and darwin.

## Summary
This PR adds `Op::ThreadSettings`, a queued settings-only update
mechanism for changing stored thread settings without starting a new
turn. It also removes the legacy `Op::OverrideTurnContext` in the same
layer, so reviewers can see the replacement and deletion together.
## Changes
- Add `Op::ThreadSettings` for settings-only queued updates.
- Emit `ThreadSettingsApplied` with the effective thread settings
snapshot after core applies an update.
- Route settings-only updates through the same submission queue as user
input.
- Migrate remaining `OverrideTurnContext` tests and callers to the
queued `Op::ThreadSettings` path.
- Delete `Op::OverrideTurnContext` from the core protocol and submission
loop.

## Why
Windows can reject plugin cache upgrades when a running MCP server still
has its working directory inside the currently active plugin version.
The existing cache refresh path replaces
`plugins/cache/<marketplace>/<plugin>` as a whole, so a live handle
under the old version can make an otherwise ordinary version bump fail.
This PR keeps the existing plugin-selection model intact while making
version bumps less disruptive.
## What changed
- When installing a new version beside an existing plugin cache root,
move only the staged version directory into place instead of replacing
the whole plugin root.
- Best-effort prune older sibling version directories after the new
version is activated.
- Preserve the existing whole-root replacement path for first installs
and same-version refreshes.
- Add regression coverage for upgrading from `1.0.0` to `2.0.0` without
replacing the plugin root.
## Verification
- `cargo test -p codex-core-plugins install_with_new_version`
- `cargo fmt --package codex-core-plugins --check`
## Why
`run_turn` had accumulated the turn-scoped skill, plugin, app, MCP,
connector-selection, and analytics setup inline. That made the
orchestration path harder to scan even though the actual turn item
injection still needs to stay in `run_turn` so ordering is explicit.
## What changed
This extracts that setup into `build_skills_and_plugins`, which returns
the combined injection `ResponseItem`s and the explicitly enabled
connector IDs. `run_turn` now keeps the required orchestration pieces:
context update recording, user input handling, connector selection
merge, and the explicit per-item `record_conversation_items` calls for
injection items.
The refactor keeps the change LOC-neutral in `core/src/session/turn.rs`
and preserves the existing response-item based injection path.
## Validation
- `cargo test -p codex-core collect_explicit_app_ids_from_skill_items`
- `just fix -p codex-core`
**Stack position:** [1 of 7]
## Summary
The first three PRs in this stack are a cleanup pass before the actual
thread settings API work.
Today, core has several overlapping "user input" ops: `UserInput`,
`UserInputWithTurnContext`, and `UserTurn`. They differ mostly in how
much next-turn state they carry, which makes the later queued thread
settings update harder to reason about and review.
This PR starts that cleanup by adding the shared
`ThreadSettingsOverrides` payload and allowing `Op::UserInput` to carry
it. Existing variants remain in place here, so this layer is mostly a
behavior-preserving API shape change plus mechanical constructor
updates.
## End State After PR3
By the end of PR3, `Op::UserInput` is the only "user input" core op. It
can carry optional thread settings overrides for callers that need to
update stored defaults with a turn, while callers without updates use
empty settings. `Op::UserInputWithTurnContext` and `Op::UserTurn` are
deleted.
## End State After PR5
By the end of PR5, core will have only two ops for this area:
- `Op::UserInput` for user-input-bearing submissions.
- `Op::ThreadSettings` for settings-only updates.

## Summary
- mark `ToolSearch` as removed and ignore stale config writes for its
legacy key
- make search tool exposure depend only on model capability, not a
feature toggle
- remove app-server enablement support and prune now-obsolete test
coverage/setup
## Verification
- `cargo test -p codex-features`
- `cargo test -p codex-tools`
- `cargo test -p codex-core search_tool_requires_model_capability`
- `cargo test -p codex-app-server experimental_feature_enablement_set_`
## Notes
- This keeps the legacy config key as a no-op for compatibility while
removing the ability to toggle the behavior off cleanly.
- No developer-facing docs update outside the touched app-server README
was needed.
Deletes the skill env var dependency prompt feature and its runtime
path. env_var entries in skill dependency metadata are now silently
ignored during skill loading.
## Why
Compaction now installs replacement history inside the session, but the
turn and compaction callers were still reaching into
`ModelClientSession` to reset websocket transport state after that
install. That made a transport-level reset part of the compaction API
even though websocket incremental request selection already checks
whether the next request is a strict extension of the previous one and
falls back to a full `response.create` when it is not.
## What changed
- Removed the compaction-side calls to `reset_websocket_session` from
`compact.rs` and `session/turn.rs`.
- Simplified pre-sampling and mid-turn compaction helpers so they return
`CodexResult<()>` instead of carrying a reset flag.
- Made `ModelClientSession::reset_websocket_session` private to
`client.rs`, leaving only the websocket timeout recovery path inside the
client as a caller.
## Validation
- `cargo test -p codex-core --test all
responses_websocket_creates_on_non_prefix`
- `cargo test -p codex-core --test all
steered_user_input_waits_for_model_continuation_after_mid_turn_compact`
- `cargo test -p codex-core --test all
pre_sampling_compact_runs_on_switch_to_smaller_context_model`
## Why
The v2 app-server permission profile fields are experimental, but the
previous migration kept a legacy object payload for profile selection.
That made clients aware of server-owned `activePermissionProfile`
metadata such as `extends`, and it kept a
`legacy_additional_writable_roots` path even though
`runtimeWorkspaceRoots` now owns runtime workspace-root selection.
This PR makes the client contract match the intended model: clients
select a permission profile by id, and the server resolves and reports
active profile provenance in response payloads.
Follow-up to #22611.
## What Changed
- Changed `thread/start`, `thread/resume`, `thread/fork`, and
`turn/start` permission profile selection to plain profile id strings.
- Changed `command/exec.permissionProfile` to a plain profile id string
for the same client/server ownership split.
- Removed `PermissionProfileSelectionParams` and the legacy `{ type:
"profile", modifications: [...] }` compatibility deserializer.
- Updated app-server, TUI, and `codex exec` call sites to send only ids,
while keeping `activePermissionProfile` as server response metadata.
- Updated app-server docs and schema fixtures for the revised
`command/exec.permissionProfile` shape.

with [ReviewStack](https://reviewstack.dev/openai/codex/pull/23360).
* #23368
* __->__ #23360
## Why
- Follows #20949.
- The above moved `thread_source` attribution from the reducer to
explicit caller provided metadata
- The `codex exec` path still omitted this metadata, leaving
exec-created threads without `thread_source`
## What Changed
- Ensures exec threads are marked as user created (`thread_source =
"user"`)
- Preserves thread-source metadata in exec’s startup session event
## Verification
- Updated unit tests to validate exec `thread_source` propagation.
- `cargo +1.93.0 test -p codex-exec --manifest-path codex-rs/Cargo.toml`
- `cargo +1.93.1 build -p codex-cli --manifest-path codex-rs/Cargo.toml`
- Validated locally with a freshly built `codex exec` run:
- Startup logs showed `thread_source: Some(User)`.
- Rollout metadata recorded `"thread_source":"user"`.
## Why
Older iTerm2 builds can be detected as supporting the image transport
that terminal pets use, but in practice they fail to render the pet flow
correctly. Instead of silently attempting image rendering, Codex should
tell the user that their iTerm2 version is too old and that upgrading is
the fix.
## What Changed
- gate iTerm2 pet auto-detection on version `3.6.0` or newer
- show a dedicated upgrade message for older or unknown iTerm2 versions
instead of the generic unsupported-terminal warning
- keep the existing generic unsupported-terminal path for non-iTerm
terminals
- add regression coverage for iTerm2 version parsing and the old-iTerm
warning path
## How to Test
1. Start Codex in iTerm2 3.6 or newer.
2. Run `/pets`.
3. Confirm the pets picker opens instead of showing a warning.
4. Start Codex in an older iTerm2 build, or exercise the equivalent test
path.
5. Run `/pets`.
6. Confirm Codex warns that pets require iTerm2 3.6 or newer and tells
the user to upgrade.
7. Also verify that a non-iTerm unsupported terminal still shows the
generic unsupported-terminal message.
Targeted tests:
- `cargo test -p codex-terminal-detection`
- `cargo test -p codex-tui pets::`
- `cargo test -p codex-tui slash_pets_on_unsupported_terminal`
- `cargo test -p codex-tui slash_pets_on_old_iterm2`
## Why
Pending model input was split across `Session`, `TurnState`, and the
agent mailbox. That made it easy for new paths to manage queued user
input or mailbox delivery outside the intended ownership boundary.
This PR consolidates the model-facing input lifecycle behind the session
input queue so turn-local pending input, next-turn queued items, and
mailbox delivery coordination are owned in one place.
## What Changed
- Added `session/input_queue.rs` to own pending input queues and mailbox
delivery coordination.
- Removed the standalone `agent/mailbox.rs` channel wrapper and store
mailbox items directly in the input queue.
- Moved pending-input mutations off `TurnState`; `TurnState` now exposes
the queue-owned storage directly for now.
- Routed abort cleanup, mailbox delivery phase changes, next-turn queued
items, and active-turn pending input through `InputQueue`.
- Boxed stack-heavy agent resume/fork startup futures that the refactor
pushed over the default test stack.
- Updated session, task, goal, stream-event, and multi-agent call sites
and tests to use the new queue ownership.

which passed when rerun in isolation.
Adding the id of the plugin that contains the MCP (if any) so we can

## Summary
- carry the plugin owner into MCP runtime provenance
- attach `plugin_id` to outbound plugin-backed MCP tool-call `_meta`
- avoid misattributing user-configured MCP servers that shadow plugin
server names

## Notes
- Attempted `cargo test -p codex-core`; it aborted in
`agent::control::tests::resume_agent_from_rollout_skips_descendants_when_parent_resume_fails`
with a stack overflow before the full suite completed.
## Why
`TurnContextItem` is the durable baseline used to reconstruct context
diffs across resume/fork. Most of the old persisted-only fields on it
are no longer read, so keeping them in rollout snapshots adds schema
surface and state that can drift without affecting reconstruction.
`summary` is the exception: older Codex versions require it to
deserialize `turn_context` records, so keep writing a default
compatibility value until that schema surface can be removed safely.
## What changed
- Removed the unused persisted fields from `TurnContextItem`: trace ids,
user/developer instructions, output schema, and truncation policy.
- Kept `summary` with a compatibility comment and made
`TurnContext::to_turn_context_item` write `ReasoningSummary::Auto`
instead of live turn state.
- Updated rollout/context reconstruction fixtures for the retained
summary field.

## Description
This PR makes `codex remote-control` behave like a foreground CLI
command by default. Running it now starts remote control, waits for
readiness, prints a clear status message with the machine name, and
stays alive until Ctrl-C.
Users who want daemon behavior can use `codex remote-control start`, and
`codex remote-control stop` now prints concise human-readable output.
`--json` remains available for scripts.
Implementation-wise, this now verifies the real app-server state instead
of just assuming startup worked. The CLI starts or connects to
app-server, probes its control socket, calls the `remoteControl/enable`
API, and waits for the remote-control status response/notification
before printing success.
For daemon mode, `codex remote-control start` also reports which managed
app-server binary was used, including its path and best-effort `codex
--version`, so failures are easier to diagnose.
## Examples
Example output:
```
> codex remote-control
Starting app-server with remote control enabled...
This machine is available for remote control as com-97826.
Press Ctrl-C to stop.
```
Error case using daemon (currently expected based on our publicly
released CLI version):
```
> ./target/debug/codex remote-control start
Starting app-server daemon with remote control enabled...
Error: app server did not become ready on /Users/owen/.codex/app-server-control/app-server-control.sock
Daemon used app-server:

```
## What changed
- `codex remote-control` now runs remote control in the foreground and
prints a Ctrl-C stop hint.
- `codex remote-control start` starts the daemon and waits for remote
control readiness before reporting success.
- `codex remote-control stop` reports stopped/not-running status in
plain language.
- Startup failures now include recent managed app-server stderr to make
daemon issues easier to diagnose.
- Added coverage for CLI output, readiness waiting, foreground shutdown,
and stderr log tailing.
## Why
Recent `rust-ci-full` failures were dominated by transient Windows
timeout clusters in process-heavy tests such as `suite::resume`,
`suite::cli_stream`, `suite::auth_env`,
`start_thread_uses_all_default_environments_from_codex_home`, and
`connect_stdio_command_initializes_json_rpc_client_on_windows`.
The goal here is to make those known flaky paths less likely to fail
full CI without relaxing the global nextest timeout policy.
## What changed
- Enable one global nextest retry with `retries = 1` so a single
transient failure can recover.
- Add a `windows_process_heavy` test group with `max-threads = 2` for
the recurring Windows subprocess/session-heavy timeout families.
- Add Windows-only slow-timeout overrides for that process-heavy group.
- Add a narrower Windows-only timeout override for
`start_thread_uses_all_default_environments_from_codex_home`, which
still exceeded the broader Windows bucket in both Windows full-CI lanes.
- Increase the `rust-ci-full` nextest job timeout from `45m` to `60m` so
Windows ARM64 still has job-level headroom after retries and targeted
per-test timeout increases.
- Keep the global `slow-timeout` unchanged at `15s`.
## Validation
Validated through `rust-ci-full` GitHub Actions reruns on this PR.
Observed improvement on the tuned Windows lanes:
- Windows x64 went from `5 timed out` to `0 timed out`.
- Windows ARM64 went from `2 timed out` to `0 timed out`.
- `start_thread_uses_all_default_environments_from_codex_home` recovered
as a flaky pass on Windows ARM64 instead of timing out.
The remaining failing tests in those runs were unrelated hard failures
outside this nextest timeout tuning.
## Why
Extensions that need to track runtime progress currently have no typed
host signal for tool execution. The goal extension in particular needs
to observe tool attempts without inspecting tool payloads, owning tool
implementations, or staying coupled to core-only runtime plumbing.
This adds a narrow lifecycle contributor API for host-owned tool
execution: extensions can observe when an accepted tool call starts and
how it finishes, while policy hooks and tool handlers continue to own
payload rewriting, blocking, and execution.
Relevant code:
-
[`ToolLifecycleContributor`](3ad2850ffc/codex-rs/ext/extension-api/src/contributors.rs (L119))
defines the extension-facing observer contract.
-
[`tool_lifecycle.rs`](3ad2850ffc/codex-rs/ext/extension-api/src/contributors/tool_lifecycle.rs)
defines the typed start/finish inputs, source, and outcome enums.
- [`notify_tool_start` /
`notify_tool_finish`](3ad2850ffc/codex-rs/core/src/tools/lifecycle.rs)
bridges core tool dispatch into the extension registry.
## What Changed
- Added `ToolLifecycleContributor` to `codex-extension-api`, including:
- `ToolStartInput`
- `ToolFinishInput`
- `ToolCallSource`
- `ToolCallOutcome`
- Added registration and lookup support on `ExtensionRegistryBuilder` /
`ExtensionRegistry`.
- Wired core tool dispatch to notify lifecycle contributors for:
- accepted tool starts
- completed tool calls, including the tool output success marker
- pre-tool-use blocks
- failures before or after the handler runs
- cancellation/abort in the parallel tool path
- Registered the goal extension as a lifecycle contributor and added the
outcome filter it will use for goal progress accounting.
## Test Coverage
- Added `dispatch_notifies_tool_lifecycle_contributors` to cover
lifecycle notification ordering and outcomes for successful and
handler-failed tool calls.
## Why
Some tool providers, especially MCP servers and dynamic tool sources,
can supply schema nodes that omit `type` and have no recognized JSON
Schema shape hints. Previously, `sanitize_json_schema` filled those
unknown nodes in as `string`, which made the schema parseable but
invented a scalar constraint that the provider did not specify. For
description-only fields, that could incorrectly steer tool arguments
away from the provider's actual accepted shape.
The Responses API accepts permissive empty schemas such as `{}` at
nested property positions, so Codex should preserve that permissive
meaning instead of coercing unknown schema nodes into a misleading
scalar type.
## What Changed
- Changed the no-hints fallback in `codex-rs/tools/src/json_schema.rs`
to clear unrecognized object schema nodes to `{}`.
- Empty schemas now remain `{}` rather than becoming `type: "string"`.
- Description-only or otherwise metadata-only nested property schemas
now become `{}` while surrounding object/array/string/number inference
still applies when recognized hints are present.
- Updated `codex-tools` and `codex-core` tests to cover top-level empty
schemas, nested empty schemas, metadata-only malformed schemas, dynamic
tools, and MCP tool specs.
## Verification
- `cargo test -p codex-tools`
- `cargo test -p codex-core
test_mcp_tool_property_missing_type_defaults_to_empty_schema`
- Manually verified the real Responses API behavior for both
empty-schema positions:
- Top-level function `parameters: {}` is accepted and echoed back as
`{"type":"object","properties":{}}`; when forced to call the tool,
Responses emitted empty object arguments: `"arguments": "{}"`.
- Nested property schema `{}` is accepted and preserved as `{}`; when
forced to call a tool with `metadata.extra`, Responses emitted
`"arguments": "{\"metadata\":{\"extra\":\"codex schema sanitizer
behavior\"}}"`.
## Summary
- make `load_global_instructions` read through an `ExecutorFileSystem`
- call global AGENTS reads with explicit `LOCAL_FS` so they stay tied to
local codex-home state
## Validation
- `bazel test --bes_backend= --bes_results_url=
--test_filter=instruction_sources_include_global_before_agents_md_docs
//codex-rs/core:core-unit-tests` on `dev`
## Why
`experimentalFeature/list` reports effective feature enablement, but
currently does not resolve it against a working directory where
project-local config.toml files can exist and toggle on/off features
when merged into the effective config after resolving the various config
layers. That means we effectively (and incorrectly) ignore features set
in project-local config.
To address that, this PR exposes an optional `thread_id` param which
allows us to load the thread's `cwd.
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server experimental_feature_list`
## Why
The session picker already supports typed search, but it ignored
bracketed paste events entirely. On macOS terminals this makes pasted
text look like a no-op on the resume screen, which is especially
noticeable when a user wants to paste part of a thread name, branch, or
path into the search field.
## What Changed
- route `TuiEvent::Paste(String)` into the session picker instead of
dropping it
- normalize pasted search text into a single-line query by collapsing
whitespace
- ignore whitespace-only pastes
- reuse the existing `set_query(...)` path so pasted searches keep the
same filtering and pagination behavior as typed input
- add focused tests for append behavior, whitespace normalization,
whitespace-only paste, and the existing search-loading path
This PR is stacked on top of #23234 and contains only the net change
relative to `etraut/clarify-resume-hints`.
## How to Test
1. Start Codex in a terminal that emits bracketed paste, for example
iTerm2 on macOS.
2. Open the resume picker so the search UI is visible.
3. Copy a term that should match one of the visible sessions, then paste
it into the picker.
4. Confirm the query updates immediately and the list filters as if the
text had been typed.
5. Also verify that pasting text with newlines or tabs still produces a
usable single-line search query.
6. Also verify that normal typed search still works and that `Esc` still
clears the query / exits as before.

## Problem
This addresses several user-reported cases where active goals were
paused even though the user had not explicitly asked for that
transition:
- the guardian approval-review circuit breaker interrupted a turn and
implicitly paused the goal
- a shutdown in one app-server instance could pause a goal while a
second instance was still actively running the same thread
- steering-style interrupts could also pause the goal even though they
are meant to redirect work, not stop the goal lifecycle
The common problem was that core treated `TurnAbortReason::Interrupted`
as an implicit request to transition the persisted goal to `paused`.
That made unrelated interrupt paths mutate goal state as a side effect,
and in the multi-app-server case it allowed stale process teardown to
pause a live goal owned by another running client.
After this change, transitioning a goal to `paused` is always an
explicit action performed by a client or another intentional goal-state
mutation. It is never an implicit transition triggered by generic
interrupt handling.
Refs #22884.
## What changed
- Remove the goal runtime path that paused active goals after
interrupted task aborts.
- Drop the now-unused abort reason from `GoalRuntimeEvent::TaskAborted`.
- Update the focused regression coverage so an interrupted active goal
still accounts usage but remains `active`.
Fixes#22300.
## Summary
MCP tool calls can appear in thread history while still in progress.
During replay, `handle_thread_item` routed every
`ThreadItem::McpToolCall` to the completion handler, so an in-progress
item with no result or error was rendered as `MCP tool call completed
without a result`.
This updates replay handling to mirror command executions: `InProgress`
MCP calls go through `on_mcp_tool_call_started`, while completed and
failed calls continue through the completion path.
## Validation
- `cargo test -p codex-tui
replayed_in_progress_mcp_tool_call_stays_active`
## Why
Fixes#21894.
When the TUI handles an MCP elicitation, the request payload already
includes the thread that generated the elicitation.
`ChatWidget::handle_elicitation_request_now` was ignoring that value and
using the currently visible chat thread instead. In a multi-session TUI,
that can send `resolve_elicitation` to an older visible thread rather
than the session that owns the pending elicitation, producing
`elicitation request not found` and leaving the prompt unresolved.
## What changed
- Parse `McpServerElicitationRequestParams.thread_id` in the ChatWidget
elicitation handler and use it for app-link, form, fallback approval,
and auto-decline resolution paths.
- Keep the existing visible-thread fallback only for malformed request
payloads with an invalid thread id.
- Update the invalid URL elicitation regression test so the visible
thread and request thread intentionally differ.
Addresses #23181
## Why
Renamed threads can share names, so hints that suggest resuming directly
by name are ambiguous. Issue #23181 asks for the picker hint to include
the thread name and thread ID in parens so users can disambiguate
safely.
## What
- Adds a shared resume hint formatter for named threads: run `codex
resume`, then select `<name> (<thread-id>)`.
- Uses that hint for /rename confirmations, TUI session summaries, and
CLI/TUI exit messages.
- Keeps direct `codex resume <thread-id>` guidance for unnamed threads.
## Verification
Manually verified that message after `/rename` and after `/exit` include
session ID in parens.

Addresses #22833, #22245, #23067
## Why
`/goal` can keep synthesizing turns even when the next turn cannot make
meaningful progress. Hard usage exhaustion can replay failing turns, and
repeated permission or external-resource blockers can keep burning
tokens while waiting for user or system intervention.
## What changed
- Add resumable `blocked` and `usageLimited` goal states. As with
`paused`, goal continuation stops with these states.
- Move to `usageLimited` after usage-limit failures.
- Allow the built-in `update_goal` tool to set `blocked` only under
explicit repeated-impasse guidance. Updated goal continuation prompt to
specify that agent should use `blocked` only when it has made at least
three attempts to get past an impasse.
Most of the files touched by this PR are because of the small app server
protocol update.
## Validation
I manually reproduced a number of situations where an agent can run into
a true impasse and verified that it properly enters `blocked` state. I
then resumed and verified that it once again entered `blocked` state
several turns later if the impasse still exists.
I also manually reproduced the usage-limit condition by creating a
simulated responses API endpoint that returns 429 errors with the
appropriate error message. Verified that the goal runtime properly moves
the goal into `usageLimited` state and TUI UI updates appropriately.
Verified that `/goal resume` resumes (and immediately goes back into
`ussageLImited` state if appropriate).
## Follow-up PRs
Small changes will be needed to the GUI clients to properly handle the
two new states.
# Summary
Before this change, the sample plugin creator could emit
placeholder-heavy manifests that fail workspace sharing, and it chose a
repo-local marketplace implicitly whenever it ran from inside a git
checkout.
This PR makes generated plugins share-ready by default. It switches
creation to the personal marketplace unless the caller explicitly opts
into repo-local paths, adds a validator that mirrors the workspace
plugin ingestion contract, and updates the skill prompt and docs to
describe the real flow.
The goal is to stop malformed generated plugins before they reach
sharing and to make the default placement match the personal marketplace
behavior users expect.
## Changes
- Generate share-safe plugin manifests instead of `[TODO: ...]`
placeholder payloads.
- Default plugin and marketplace creation to `~/plugins` and
`~/.agents/plugins/marketplace.json`.
- Keep repo-local marketplace creation available through explicit
`--path` and `--marketplace-path` arguments.
- Add `validate_plugin.py` to check manifests, companion files, skill
frontmatter, skill agent YAML, asset paths, and backend-shaped contracts
before sharing.
- Refresh the plugin creator skill text, reference docs, and default
prompt to describe validation and the personal default.
## Design decisions
- The validator tracks the workspace ingestion schema directly,
including the required `defaultPrompt` alias handling and skill
`agents/openai.yaml` checks.
- The validator keeps one intentional extra preflight rule: leftover
`[TODO: ...]` placeholders are rejected before sharing even when a
single placeholder would not independently violate backend type
validation.
- Repo-local creation stays possible, but it is now explicit instead of
cwd-sensitive.
## Testing
Tests: targeted Python syntax checks, plugin skill validation, staged
diff whitespace validation, 15 generated plugin smoke runs, backend
manifest-schema acceptance for all 15 generated bundles, and a git-repo
cwd regression proving the creator still writes to the personal
marketplace by default.
## Why
`rust-ci-full` failures currently leave downstream investigation
reconstructing basic test facts from raw logs. `cargo nextest` can emit
standard JUnit XML for each lane, which gives us a small structured
artifact for post-run failure analysis without changing the test
execution model.
## What changed
- enable nextest JUnit output in `codex-rs/.config/nextest.toml`
- upload the lane-scoped JUnit XML artifact from each `rust-ci-full`
test lane
## Verification
- `rust-ci-full` run `26018931531` on head
`52d77c60e79b36859d944ef28a36b014055c5c48` produced JUnit artifacts for
macOS, Linux x64 remote, Windows x64, and Windows ARM64 test lanes
- `rust-ci-full` run `26021241006` on the same head produced the missing
Linux ARM JUnit artifact after the first run lost that runner before
export
- downloaded all five lane JUnit artifacts and verified each contains
non-empty test counters and failure data
## Why
The legacy Windows sandbox still carried a `persist_aces` mode switch,
even though the only path that meaningfully applies filesystem ACEs
today is `workspace-write`, which already uses the persistent behavior.
Legacy read-only sessions rely on the read-only capability SID rather
than per-command filesystem ACE mutation, so the temporary cleanup
branch had become conceptual overhead without a corresponding behavioral
need.
Removing that split makes the ACL lifecycle match the current sandbox
model more directly and trims the guard/revocation plumbing from the
legacy launcher paths.
## What changed
- Removed the `persist_aces` parameter from legacy ACL preparation.
- Made legacy deny-read handling always use the persistent
reconciliation path.
- Dropped guard tracking and post-exit ACE revocation from both capture
and unified-exec legacy flows.
- Kept workspace `.codex` / `.agents` protection tied directly to
`WorkspaceWrite` instead of an intermediate persistence flag.
## Verification
- `cargo fmt -p codex-windows-sandbox`
- `git diff --check`
- `cargo test -p codex-windows-sandbox`
- 85 passed, 2 ignored, 2 (unrelated) failed locally.
## Why
`TurnDiffTracker` computes a display root so turn diffs can be rendered
repo-relative. For remote exec-server turns, the selected turn `cwd` may
exist only inside the selected environment, but `run_turn` was
discovering the git root through the local host filesystem. When that
lookup failed, nested remote-session diffs fell back to the nested `cwd`
and showed `/tmp/...`-prefixed paths instead of repo-relative paths.
## What changed
- Resolve the diff display root from the primary selected turn
environment when one exists, using that environment's filesystem and
`cwd`.
- Add `codex_git_utils::get_git_repo_root_with_fs(...)` so git-root
discovery can run against an `ExecutorFileSystem`, including remote
environments.
- Reuse that helper from `resolve_root_git_project_for_trust(...)` and
add coverage for `.git` gitdir-pointer detection.
## Validation

## Why
Ctrl+C can take a noticeable amount of time to finish when the TUI is
waiting for the app-server thread shutdown path to complete. Before this
change, the UI could look like it had not accepted the shutdown request
because the composer and cursor remained in their normal interactive
state during that wait.
This PR makes the accepted shutdown visible immediately. It does not add
an artificial sleep or change the shutdown timeout; it only draws one
final feedback frame before continuing through the existing shutdown
flow.
## What Changed
- On `ExitMode::ShutdownFirst`, the TUI now renders shutdown feedback
before awaiting the existing thread shutdown future.
- The bottom pane disables composer input, which hides the cursor
through the existing disabled-input cursor path.
- The composer shows `Shutting down...` as the disabled input hint and
suppresses footer content so the shutdown acknowledgement is not
competing with shortcut/status text.
- The logout path uses the same feedback path before shutting down.
## How to Test
1. Start Codex from this branch.
2. Press `Ctrl+C` to request shutdown.
3. If shutdown takes long enough to observe, confirm the composer
changes to `› Shutting down...`, the cursor disappears, and no footer
hint is rendered below it.
4. Regression check: repeat with text already typed in the composer and
confirm the visible row still switches to `Shutting down...` while the
draft remains preserved internally until the process exits.
Targeted tests:
- `cargo test -p codex-tui
shutdown_in_progress_disables_input_and_uses_hint_without_footer`
- `cargo test -p codex-tui bottom_pane::footer::tests::`
## Local Validation Note
`cargo test -p codex-tui` still aborts in
`app::tests::discard_side_thread_removes_agent_navigation_entry` with a
stack overflow. That same test also failed when run alone locally, and
the failure appears unrelated to this shutdown feedback path.
## Why
Windows release artifacts currently import `VCRUNTIME140.dll` and
`VCRUNTIME140_1.dll`. That becomes observable on clean Windows machines
that do not already have the VC++ runtime available globally:
- Desktop Store launches can fail after the app relocates `codex.exe`
out of `WindowsApps`, which means an MSIX-level VCLibs dependency does
not protect the relocated CLI/app-server process.
- The npm CLI path reproduces the same missing-DLL startup failure when
`System32\vcruntime140_1.dll` is hidden and `PATH` is stripped of
incidental fallback copies.
In that setup, the existing Windows binary exits with `0xC0000135` /
`-1073741515` before Codex code runs.
## What changed
- Add `-C target-feature=+crt-static` to the existing MSVC-only Cargo
rustflags in `codex-rs/.cargo/config.toml`.
- Preserve the existing `/STACK:8388608` linker setting in the same
target block.
This keeps the change scoped to Windows MSVC builds and avoids altering
non-Windows or GNU target behavior.
## Verification
I built an x64 Windows release probe with static CRT linkage and the
normal 8 MiB stack reserve, then verified:
- `dumpbin /dependents codex.exe` no longer reports `VCRUNTIME140.dll`
or `VCRUNTIME140_1.dll`.
- `dumpbin /headers codex.exe` reports `800000 size of stack reserve`.
- With `System32\vcruntime140_1.dll` hidden and `PATH` stripped to
Windows system directories only:
- the old npm CLI path exits `-1073741515`
- the rebuilt static-CRT `codex.exe --version` succeeds with exit code
`0`
- the rebuilt TUI starts successfully
I also confirmed `codex.exe app-server --listen ws://127.0.0.1:0` starts
and binds normally with the static-CRT artifact.
## Why
The client and tool pipeline still carried compatibility code for legacy
structured shell output. Current shell and apply_patch responses are
already plain text for model consumption, so keeping a
JSON-serialization path plus shell-item rewrite logic makes the request
formatter and tests preserve a format we do not need anymore.
## What Changed
- Removed the client-side shell output rewrite from
`core/src/client_common.rs`.
- Removed the structured exec-output formatter and the shell `freeform`
switch so tool emitters use one model-facing formatter.
- Collapsed apply_patch/shell serialization tests around the remaining
plain-text output expectations and removed duplicate one-variant
parameterized cases.
- Kept the `ApplyPatchModelOutput::ShellCommandViaHeredoc` compatibility
input shape, but no longer treats it as a separate output-format mode.
## Validation
- `cargo test -p codex-core client_common`
- `cargo test -p codex-core shell_serialization`
- `cargo test -p codex-core apply_patch_cli`
- `just fix -p codex-core`
## Documentation
No external Codex documentation update is needed.
## Why
Codex TUI startup still feels slower than 0.117.0 after the app-server
move in 0.118.0. A visible chunk of launch-to-input latency comes from
serial terminal startup probes: cursor position, keyboard enhancement
support, and default foreground/background color queries can each wait
on terminal responses before the first usable frame.
Refs #16335.
## What
This PR batches the terminal startup probes into one bounded probe. It
also reuses the probed cursor position and default colors during TUI
setup, fast-paths the primary-device-attributes fallback as keyboard
enhancement unsupported, and keeps lightweight startup timing logs for
future tuning.
The startup telemetry is intentionally left in production: it records
phase timings for terminal probes and initial-frame scheduling so future
startup regressions can be diagnosed from normal logs rather than
re-adding one-off debug instrumentation.
## Benchmark
In the local pty startup benchmark, the pre-optimization `main` baseline
was about 250.5ms median from launch to accepted chat input. This
probe-only branch measured about 152ms median, for an approximate
savings of 95-100ms.

## Summary
Provider deployments such as Bedrock manage rate limits and billing
outside ChatGPT, so the `/status` link to the ChatGPT usage page is
irrelevant and confusing for those users. Custom providers that are
explicitly configured to use OpenAI/ChatGPT auth still point at
OpenAI-backed usage, so they should keep the link.
## Changes
- Render the ChatGPT usage note only when the configured provider uses
OpenAI auth.
- Keep the note hidden when `/status` displays a provider such as
Bedrock that manages limits elsewhere.
- Add regression coverage for both Bedrock and a custom OpenAI-auth
proxy provider.
## Manual Repro
1. Configure Codex with a non-OpenAI-auth provider, for example
`model_provider = "amazon-bedrock"`.
2. Start the TUI and run `/status`.
3. Confirm the status card shows the custom provider, for example `Model
provider: Amazon Bedrock`, and does not show
`https://chatgpt.com/codex/settings/usage`.
4. Configure a custom provider that proxies to OpenAI and has
OpenAI/ChatGPT auth enabled.
5. Run `/status` again and confirm the ChatGPT usage link appears for
that OpenAI-auth provider.
## Summary
Fixes#22726.
After a Responses stream disconnect, the live TUI could keep accepting
prompts while leaving partially streamed assistant output in its
transient streaming-cell form. That made fenced diffs or SVG/XML-like
content appear as raw transcript text until the user closed the TUI and
resumed the same session, which rebuilt the transcript from saved
history.
This change finalizes the active answer stream before generic
failed-turn cleanup clears the stream controller, so the live transcript
takes the same source-backed markdown consolidation path as a successful
turn.
## Reviewer repro
1. Start a local Codex TUI session.
2. Trigger an assistant turn that streams markdown content, especially a
fenced diff or SVG/XML-like block.
3. Force or encounter a non-retry stream disconnect before the turn
completes.
4. Continue using the same still-open TUI session.
5. Before this fix, the live history can stay raw/plain even though
`codex resume` renders the same session normally.
6. After this fix, the failed-turn path consolidates the partial stream
before rendering the error, so the live TUI keeps normal transcript
rendering.
## Why
`codex exec resume` should have the same structured-output support as
top-level `codex exec`. Without `--output-schema`, multi-turn automation
has to choose between resumed session context and schema-validated JSON
output.
Fixes#22998.
## What changed
- Marked `--output-schema` as a global `codex exec` flag so it can be
passed after `resume`.
- Reused the existing output schema plumbing so resumed turns attach the
schema to the final response request while preserving session context.
## Why
After turning Fast mode off in the TUI, returning from a side thread
could make `Fast` appear again in the main chat widget. The opt-out
itself was still persisted; the display was being rebuilt from stale
cached `ThreadSessionState` data, which made it look like Fast had been
re-enabled.
Fixes#23104.
## What changed
- Keep the active thread's cached `service_tier` in sync whenever the
user persists a service-tier selection.
- Update both the primary-thread snapshot and the thread event store so
restored TUI state reflects the current tier.
- Add a focused regression test for clearing a cached Fast tier.
## Manual repro
1. Start a TUI session where `Fast` is enabled by default.
2. Run `/fast` and turn Fast mode off. Confirm `Fast` disappears from
the chat widget display.
3. Re-enter thread navigation via either path:
- Run `/side test`, then return to the main thread.
- Run `/agent`, enter a child thread, then return to the main thread.
4. Before this fix, `Fast` reappears in the main chat widget display
even though the opt-out was already persisted.
5. After this fix, `Fast` stays cleared.

## Why
Goal creation and completion are moving through the goal extension, but
the rest of Codex still observes goal state through `ThreadGoalUpdated`
events. Without an event from the extension-owned tool path, a
model-initiated `create_goal` or `update_goal` can mutate the backend
and return a tool result while app-server and TUI listeners miss the
goal state transition.
## What changed
- Added `GoalEventEmitter` as a small wrapper around the host
`ExtensionEventSink` to build `EventMsg::ThreadGoalUpdated` events for
goal updates.
- Threaded the registry event sink into `GoalExtension` and the
`GoalToolExecutor`s created by the extension. The public
`GoalExtension::new` constructor keeps a `NoopExtensionEventSink`
fallback for standalone use.
- Emitted a goal update after successful `create_goal` and `update_goal`
tool calls. Until `ToolCall` exposes the current turn submission id,
these events use the tool call id as the event id and leave `turn_id`
unset.
