Summary
- rename the `collab` handlers and UI files to `multi_agents` to match
the new naming
- update module references and specs so the handlers and TUI widgets
consistently use the renamed files
- keep the existing functionality while aligning file and module names
with the multi-agent terminology
The idea is to have 2 family of agents.
1. Built-in that we packaged directly with Codex
2. User defined that are defined using the `agents_config.toml` file. It
can reference config files that will override the agent config. This
looks like this:
```
version = 1
[agents.explorer]
description = """Use `explorer` for all codebase questions.
Explorers are fast and authoritative.
Always prefer them over manual search or file reading.
Rules:
- Ask explorers first and precisely.
- Do not re-read or re-search code they cover.
- Trust explorer results without verification.
- Run explorers in parallel when useful.
- Reuse existing explorers for related questions."""
config_file = "explorer.toml"
```
Summary
- rename the collab feature key to multi_agent while keeping the Feature
enum unchanged
- add legacy alias support so both "multi_agent" and "collab" map to the
same feature
- cover the alias behavior with a new unit test
## Summary
- make `rust_test` targets generated from `tests/*.rs` use Cargo-style
crate names (file stem) so snapshot names match Cargo (`all__...`
instead of Bazel-derived names)
- split lib vs `tests/*.rs` test env wiring in `codex_rust_crate` to
keep existing lib snapshot behavior while applying Bazel
runfiles-compatible workspace root for `tests/*.rs`
- compute the `tests/*.rs` snapshot workspace root from package depth so
`insta` resolves committed snapshots under Bazel `--noenable_runfiles`
## Validation
- `bazelisk test //codex-rs/core:core-all-test
--test_arg=suite::compact:: --cache_test_results=no`
- `bazelisk test //codex-rs/core:core-all-test
--test_arg=suite::compact_remote:: --cache_test_results=no`
###### Context
unknown model warning added in #11690 has
[issues](https://github.com/openai/codex/actions/runs/22047424710/job/63700733887)
on ubuntu runners because we potentially emit it on all new turns,
including ones with intentionally fake models (i.e., `mock-model` in a
test).
###### Fix
change the warning to only emit on user turns/review turns.
###### Tests
CI now passes on ubuntu, still passes locally
### What changed
1. Removed per-turn MCP selection reset in `core/src/tasks/mod.rs`.
2. Added `SessionState::set_mcp_tool_selection(Vec<String>)` in
`core/src/state/session.rs` for authoritative restore behavior (deduped,
order-preserving, empty clears).
3. Added rollout parsing in `core/src/codex.rs` to recover
`active_selected_tools` from prior `search_tool_bm25` outputs:
- tracks matching `call_id`s
- parses function output text JSON
- extracts `active_selected_tools`
- latest valid payload wins
- malformed/non-matching payloads are ignored
4. Applied restore logic to resumed and forked startup paths in
`core/src/codex.rs`.
5. Updated instruction text to session/thread scope in
`core/templates/search_tool/tool_description.md`.
6. Expanded tests in `core/tests/suite/search_tool.rs`, plus unit
coverage in:
- `core/src/codex.rs`
- `core/src/state/session.rs`
### Behavior after change
1. Search activates matched tools.
2. Additional searches union into active selection.
3. Selection survives new turns in the same thread.
4. Resume/fork restores selection from rollout history.
5. Separate threads do not inherit selection unless forked.
### What
It's currently unclear when the harness falls back to the default,
generic `ModelInfo`. This happens when the `remote_models` feature is
disabled or the model is truly unknown, and can lead to bad performance
and issues in the harness.
Add a user-facing warning when this happens so they are aware when their
setup is broken.
### Tests
Added tests, tested locally.
This PR keeps compaction context-layout test coverage separate from
runtime compaction behavior changes, so runtime logic review can stay
focused.
## Included
- Adds reusable context snapshot helpers in
`core/tests/common/context_snapshot.rs` for rendering model-visible
request/history shapes.
- Standardizes helper naming for readability:
- `format_request_input_snapshot`
- `format_response_items_snapshot`
- `format_labeled_requests_snapshot`
- `format_labeled_items_snapshot`
- Expands snapshot coverage for both local and remote compaction flows:
- pre-turn auto-compaction
- pre-turn failure/context-window-exceeded paths
- mid-turn continuation compaction
- manual `/compact` with and without prior user turns
- Captures both sides where relevant:
- compaction request shape
- post-compaction history layout shape
- Adds/uses shared request-inspection helpers so assertions target
structured request content instead of ad-hoc JSON string parsing.
- Aligns snapshots/assertions to current behavior and leaves explicit
`TODO(ccunningham)` notes where behavior is known and intentionally
deferred.
## Not Included
- No runtime compaction logic changes.
- No model-visible context/state behavior changes.
## Summary
- add a distinct `linux_bubblewrap` sandbox tag when the Linux
bubblewrap pipeline feature is enabled
- thread the bubblewrap feature flag into sandbox tag generation for:
- turn metadata header emission
- tool telemetry metric tags and after-tool-use hooks
- add focused unit tests for `sandbox_tag` precedence and Linux
bubblewrap behavior
## Validation
- `just fmt`
- `cargo clippy -p codex-core --all-targets`
- `cargo test -p codex-core sandbox_tags::tests`
- started `cargo test -p codex-core` and stopped it per request

### Description
#### Summary
Introduces the core plumbing required for structured network approvals
#### What changed
- Added structured network policy decision modeling in core.
- Added approval payload/context types needed for network approval
semantics.
- Wired shell/unified-exec runtime plumbing to consume structured
decisions.
- Updated related core error/event surfaces for structured handling.
- Updated protocol plumbing used by core approval flow.
- Included small CLI debug sandbox compatibility updates needed by this
layer.
#### Why
establishes the minimal backend foundation for network approvals without
yet changing high-level orchestration or TUI behavior.
#### Notes
- Behavior remains constrained by existing requirements/config gating.
- Follow-up PRs in the stack handle orchestration, UX, and app-server
integration.

## Summary
This PR fixes a race in `js_repl` tool-call draining that could leave an
exec waiting indefinitely for in-flight tool calls to finish.
The fix is in:
-
`/Users/fjord/code/codex-jsrepl-seq/codex-rs/core/src/tools/js_repl/mod.rs`
## Problem
`js_repl` tracks in-flight tool calls per exec and waits for them to
drain on completion/timeout/cancel paths.
The previous wait logic used a check-then-wait pattern with `Notify`
that could miss a wakeup:
1. Observe `in_flight > 0`
2. Drop lock
3. Register wait (`notified().await`)
If `notify_waiters()` happened between (2) and (3), the waiter could
sleep until another notification that never comes.
## What changed
- Updated all exec-tool-call wait loops to create an owned notification
future while holding the lock:
- use `Arc<Notify>::notified_owned()` instead of cloning notify and
awaiting later.
- Applied this consistently to:
- `wait_for_exec_tool_calls`
- `wait_for_all_exec_tool_calls`
- `wait_for_exec_tool_calls_map`
This preserves existing behavior while eliminating the lost-wakeup
window.
## Test coverage
Added a regression test:
- `wait_for_exec_tool_calls_map_drains_inflight_calls_without_hanging`
The test repeatedly races waiter/finisher tasks and asserts bounded
completion to catch hangs.
## Impact
- No API changes.
- No user-facing behavior changes intended.
- Improves reliability of exec lifecycle boundaries when tool calls are
still in flight.

## Summary
Fixes a flaky/panicking `js_repl` image-path test by running it on a
multi-thread Tokio runtime and tightening assertions to focus on real
behavior.
## Problem
`js_repl_can_attach_image_via_view_image_tool` in
`/Users/fjord/code/codex-jsrepl-seq/codex-rs/core/src/tools/js_repl/mod.rs`
can panic under single-thread test runtime with:
`can call blocking only when running on the multi-threaded runtime`
It also asserted a brittle user-facing text string.
## Changes
1. Updated the test runtime to:
`#[tokio::test(flavor = "multi_thread", worker_threads = 2)]`
2. Removed the brittle `"attached local image path"` string assertion.
3. Kept the concrete side-effect assertions:
- tool call succeeds
- image is actually injected into pending input (`InputImage` with
`data:image/png;base64,...`)
## Why this is safe
This is test-only behavior. No production runtime code paths are
changed.
## Validation
- Ran:
`cargo test -p codex-core
tools::js_repl::tests::js_repl_can_attach_image_via_view_image_tool --
--nocapture`
- Result: pass

## Summary
- Created branch zuxin/read-path-update from main.
- Copied codex-rs/core/templates/memories/read_path.md from the current
branch.
- Committed the content change.
## Testing
Not run (content copy + commit only).
Currently, if there are syntax errors detected in the starlark rules
file, the entire policy is silently ignored by the CLI. The app server
correctly emits a message that can be displayed in a GUI.
This PR changes the CLI (both the TUI and non-interactive exec) to fail
when the rules file can't be parsed. It then prints out an error message
and exits with a non-zero exit code. This is consistent with the
handling of errors in the config file.
This addresses #11603
## Summary
- add a shared `codex-core` sleep inhibitor that uses native macOS IOKit
assertions (`IOPMAssertionCreateWithName` / `IOPMAssertionRelease`)
instead of spawning `caffeinate`
- wire sleep inhibition to turn lifecycle in `tui` (`TurnStarted`
enables; `TurnComplete` and abort/error finalization disable)
- gate this behavior behind a `/experimental` feature toggle
(`[features].prevent_idle_sleep`) instead of a dedicated `[tui]` config
flag
- expose the toggle in `/experimental` on macOS; keep it under
development on other platforms
- keep behavior no-op on non-macOS targets

## Semantics and API references
- This PR targets `caffeinate -i` semantics: prevent *idle system sleep*
while allowing display idle sleep.
- `caffeinate -i` mapping in Apple open source (`assertionMap`):
- `kIdleAssertionFlag -> kIOPMAssertionTypePreventUserIdleSystemSleep`
- Source:
https://github.com/apple-oss-distributions/PowerManagement/blob/PowerManagement-1846.60.12/caffeinate/caffeinate.c#L52-L54

## Codex Electron vs this PR (full stack path)
- Codex Electron app requests sleep blocking with
`powerSaveBlocker.start("prevent-app-suspension")`:
-
https://github.com/openai/codex/blob/main/codex/codex-vscode/electron/src/electron-message-handler.ts
- Electron maps that string to Chromium wake lock type
`kPreventAppSuspension`:
-
https://github.com/electron/electron/blob/main/shell/browser/api/electron_api_power_save_blocker.cc
- Chromium macOS backend maps wake lock types to IOKit assertion
constants and calls IOKit:
- `kPreventAppSuspension -> kIOPMAssertionTypeNoIdleSleep`
- `kPreventDisplaySleep / kPreventDisplaySleepAllowDimming ->
kIOPMAssertionTypeNoDisplaySleep`
-
https://github.com/chromium/chromium/blob/main/services/device/wake_lock/power_save_blocker/power_save_blocker_mac.cc
## Why this PR uses a different macOS constant name
- This PR uses `"PreventUserIdleSystemSleep"` directly, via
`IOPMAssertionCreateWithName`, in
`codex-rs/core/src/sleep_inhibitor.rs`.
- Apple’s IOKit header documents `kIOPMAssertionTypeNoIdleSleep` as
deprecated and recommends `kIOPMAssertPreventUserIdleSystemSleep` /
`kIOPMAssertionTypePreventUserIdleSystemSleep`:
-
https://github.com/apple-oss-distributions/IOKitUser/blob/IOKitUser-100222.60.2/pwr_mgt.subproj/IOPMLib.h#L1000-L1030
- So Chromium and this PR are using different constant names, but
semantically equivalent idle-system-sleep prevention behavior.
## Future platform support
The architecture is intentionally set up for multi-platform extensions:
- UI code (`tui`) only calls `SleepInhibitor::set_turn_running(...)` on
turn lifecycle boundaries.
- Platform-specific behavior is isolated in
`codex-rs/core/src/sleep_inhibitor.rs` behind `cfg(...)` blocks.
- Feature exposure is centralized in `core/src/features.rs` and surfaced
via `/experimental`.
- Adding new OS backends should not require additional TUI wiring; only
the backend internals and feature stage metadata need to change.
Potential follow-up implementations:
- Windows:
- Add a backend using Win32 power APIs
(`SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED)` as
baseline).
- Optionally move to `PowerCreateRequest` / `PowerSetRequest` /
`PowerClearRequest` for richer assertion semantics.
- Linux:
- Add a backend using logind inhibitors over D-Bus
(`org.freedesktop.login1.Manager.Inhibit` with `what="sleep"`).
- Keep a no-op fallback where logind/D-Bus is unavailable.
This PR keeps the cross-platform API surface minimal so future PRs can
add Windows/Linux support incrementally with low churn.

## Why
`compact_resume_after_second_compaction_preserves_history` has been
intermittently flaky in Windows CI.
The test had two one-shot request matchers in the second compact/resume
phase that could overlap, and it waited for the first `Warning` event
after compaction. In practice, that made the test sensitive to
platform/config-specific prompt shape and unrelated warning timing.
## What Changed
- Hardened the second compaction matcher in
`codex-rs/core/tests/suite/compact_resume_fork.rs` so it accepts
expected compact-request variants while explicitly excluding the
`AFTER_SECOND_RESUME` payload.
- Updated `compact_conversation()` to wait for the specific compaction
warning (`COMPACT_WARNING_MESSAGE`) rather than any `Warning` event.
- Added an inline comment explaining why the matcher is intentionally
broad but disjoint from the follow-up resume matcher.
## Test Plan
- `cargo test -p codex-core --test all
suite::compact_resume_fork::compact_resume_after_second_compaction_preserves_history
-- --exact`
- Repeated the same test in a loop (40 runs) to check for local
nondeterminism.
## Summary
- Limit `search_tool_bm25` indexing to `codex_apps` tools only, so
non-Apps MCP servers are no longer discoverable through this search
path.
- Move search-tool discovery guidance into the `search_tool_bm25` tool
description (via template include) instead of injecting it as a separate
developer message.
- Update Apps discovery guidance wording to clarify when to use
`search_tool_bm25` for Apps-backed systems (for example Slack, Google
Drive, Jira, Notion) and when to call tools directly.
- Remove dead `core` helper code (`filter_codex_apps_mcp_tools` and
`codex_apps_connector_id`) that is no longer used after the
tool-selection refactor.
- Update `core` search-tool tests to assert codex-apps-only behavior and
to validate guidance from the tool description.
## Validation
- ✅ `just fmt`
- ✅ `cargo test -p codex-core search_tool`
- ⚠️ `cargo test -p codex-core` was attempted, but the run repeatedly
stalled on
`tools::js_repl::tests::js_repl_can_attach_image_via_view_image_tool`.
## Tickets
- None
Summary
- make the phase1 memories schema require `rollout_slug` while still
allowing it to be `null`
- update the corresponding test to check the required fields and
nullable type list
Testing
- Not run (not requested)
## Summary
If the model suggests a bad rule, don't show it to the user. This does
not impact the parsing of existing rules, just the ones we show.
## Testing
- [x] Added unit tests
- [x] Ran locally
When `app/list` is called with `force_refetch=True`, we should seed the
results with what is already cached instead of starting from an empty
list. Otherwise when we send app/list/updated events, the client will
first see an empty list of accessible apps and then get the updated one.
We've had a few cases recently where someone enabled a feature flag for
a feature that's still under development or experimental. This test
should prevent this.
### Motivation
- Git subcommand matching was being classified as "dangerous" and caused
benign developer workflows (for example `git push --force-with-lease`)
to be blocked by the preflight policy.
- The change aligns behavior with the intent to reserve the dangerous
checklist for truly destructive shell ops (e.g. `rm -rf`) and avoid
surprising developer-facing blocks.
### Description
- Remove git-specific subcommand checks from
`is_dangerous_to_call_with_exec` in
`codex-rs/shell-command/src/command_safety/is_dangerous_command.rs`,
leaving only explicit `rm` and `sudo` passthrough checks.
- Deleted the git-specific helper logic that classified `reset`,
`branch`-delete, `push` (force/delete/refspec) and `clean --force` as
dangerous.
- Updated unit tests in the same file to assert that various `git
reset`/`git branch`/`git push`/`git clean` variants are no longer
classified as dangerous.
- Kept `find_git_subcommand` (used by safe-command classification)
intact so safe/unsafe parsing elsewhere remains functional.
### Testing
- Ran formatter with `just fmt` successfully.
- Ran unit tests with `cargo test -p codex-shell-command` and all tests
passed (`144 passed; 0 failed`).

## Summary
This PR delivers the first small, shippable step toward model-visible
state diffing by making
`TurnContextItem` more complete and standardizing how it is built.
Specifically, it:
- Adds persisted network context to `TurnContextItem`.
- Introduces a single canonical `TurnContext -> TurnContextItem`
conversion path.
- Routes existing rollout write sites through that canonical conversion
helper.
No context injection/diff behavior changes are included in this PR.
## Why this change
The design goal is to make `TurnContextItem` the canonical source of
truth for context-diff
decisions.
Before this PR:
- `TurnContextItem` did not include all TurnContext-derived environment
inputs needed for v1
completeness.
- Construction was duplicated at multiple write sites.
This PR addresses both with a minimal, reviewable change.
## Changes
### 1) Extend `TurnContextItem` with network state
- Added `TurnContextNetworkItem { allowed_domains, denied_domains }`.
- Added `network: Option<TurnContextNetworkItem>` to `TurnContextItem`.
- Kept backward compatibility by making the new field optional and
skipped when absent.
Files:
- `codex-rs/protocol/src/protocol.rs`
### 2) Canonical conversion helper
- Added `TurnContext::to_turn_context_item(collaboration_mode)` in core.
- Added internal helper to derive network fields from
`config_layer_stack.requirements().network`.
Files:
- `codex-rs/core/src/codex.rs`
### 3) Use canonical conversion at rollout write sites
- Replaced ad hoc `TurnContextItem { ... }` construction with
`to_turn_context_item(...)` in:
- sampling request path
- compaction path
Files:
- `codex-rs/core/src/codex.rs`
- `codex-rs/core/src/compact.rs`
### 4) Update fixtures/tests for new optional field
- Updated existing `TurnContextItem` literals in tests to include
`network: None`.
- Added protocol tests for:
- deserializing old payloads with no `network`
- serializing when `network` is present
Files:
- `codex-rs/core/tests/suite/resume_warning.rs`
- No replay/diff logic changes.
- Persisted rollout `TurnContextItem` now carries additional network
context when available.
- Older rollout lines without `network` remain readable.
Adds a new apps_mcp_gateway flag to route Apps MCP calls through
https://api.openai.com/v1/connectors/mcp/ when enabled, while keeping
legacy MCP routing as default.
## Why
We currently carry multiple permission-related concepts directly on
`Config` for shell/unified-exec behavior (`approval_policy`,
`sandbox_policy`, `network`, `shell_environment_policy`,
`windows_sandbox_mode`).
Consolidating these into one in-memory struct makes permission handling
easier to reason about and sets up the next step: supporting named
permission profiles (`[permissions.PROFILE_NAME]`) without changing
behavior now.
This change is mostly mechanical: it updates existing callsites to go
through `config.permissions`, but it does not yet refactor those
callsites to take a single `Permissions` value in places where multiple
permission fields are still threaded separately.
This PR intentionally **does not** change the on-disk `config.toml`
format yet and keeps compatibility with legacy config keys.
## What Changed
- Introduced `Permissions` in `core/src/config/mod.rs`.
- Added `Config::permissions` and moved effective runtime permission
fields under it:
- `approval_policy`
- `sandbox_policy`
- `network`
- `shell_environment_policy`
- `windows_sandbox_mode`
- Updated config loading/building so these effective values are still
derived from the same existing config inputs and constraints.
- Updated Windows sandbox helpers/resolution to read/write via
`permissions`.
- Threaded the new field through all permission consumers across core
runtime, app-server, CLI/exec, TUI, and sandbox summary code.
- Updated affected tests to reference `config.permissions.*`.
- Renamed the struct/field from
`EffectivePermissions`/`effective_permissions` to
`Permissions`/`permissions` and aligned variable naming accordingly.
