Preserve the subagent inbox foundation behavior on the current origin/main base and collapse the branch back to a single commit for easier future restacks.
## Why
`core/src/tools/spec.rs` still bundled a set of pure local-host tool
builders with the orchestration that actually decides when those tools
are exposed and which handlers back them. That made `codex-core`
responsible for JSON/tool-shape construction that does not depend on
session state, and it kept the `codex-tools` migration from taking a
meaningfully larger bite out of `spec.rs`.
This PR moves that reusable spec-building layer into `codex-tools` while
leaving feature gating, handler registration, and runtime-coupled
descriptions in `codex-core`.
## What changed
- added `codex-rs/tools/src/local_tool.rs` for the pure builders for
`exec_command`, `write_stdin`, `shell`, `shell_command`, and
`request_permissions`
- added `codex-rs/tools/src/view_image.rs` for the `view_image` tool
spec and output schema so the extracted modules stay right-sized
- rewired `codex-rs/core/src/tools/spec.rs` to call those extracted
builders instead of constructing these specs inline
- kept the `request_permissions` description source in `codex-core`,
with `codex-tools` taking the description as input so the crate boundary
does not grow a dependency on handler/runtime code
- moved the direct constructor coverage for this slice from
`codex-rs/core/src/tools/spec_tests.rs` into
`codex-rs/tools/src/local_tool_tests.rs` and
`codex-rs/tools/src/view_image_tests.rs`
- updated `codex-rs/tools/README.md` to reflect that `codex-tools` now
owns this local-host spec layer
## Test plan
- `CARGO_TARGET_DIR=/tmp/codex-tools-local-host cargo test -p
codex-tools`
- `CARGO_TARGET_DIR=/tmp/codex-core-local-tools cargo test -p codex-core

Fixes#16091.
The app-server TUI was truncating the filtered mention candidate list to
`MAX_POPUP_ROWS`, so the `$` skills picker only exposed the first 8
matches. That made it look like many skills were missing and prevented
keyboard navigation beyond the first page, even though direct
`$skill-name` insertion still worked.
Testing: I manually verified the regression and confirmed the fix.
## Why
`thread_start_params_from_config()` is supposed to forward the effective
`approvals_reviewer` into the app-server request, but these tests were
constructing that config through `ConfigBuilder::build()`, which also
loads ambient system and managed config layers. On machines with an
admin or host-level reviewer override, the manual-only case could
inherit `guardian_subagent` and fail even though the exec-side mapping
was correct.
## What changed
- Set `approvals_reviewer` explicitly via `harness_overrides` in the two
`thread_start_params_*review_policy*` tests in
`codex-rs/exec/src/lib.rs`.
- Removed the dependence on default config resolution and temp
`config.toml` writes so the tests exercise only the reviewer-to-request
mapping in `codex-exec`.
## Testing
- `cargo test -p codex-exec`
## Why
The longer-term `codex-tools` migration is to move pure tool-definition
and tool-spec plumbing out of `codex-core` while leaving session- and
runtime-coupled orchestration behind.
The remaining code-mode adapter layer in
`core/src/tools/code_mode_description.rs` was a good next extraction
seam because it only transformed `ToolSpec` values for code mode and
already delegated the low-level description rendering to
`codex-code-mode`.
## What Changed
- added `codex-rs/tools/src/code_mode.rs` with
`augment_tool_spec_for_code_mode()` and
`tool_spec_to_code_mode_tool_definition()`
- added focused unit coverage in `codex-rs/tools/src/code_mode_tests.rs`
- rewired `core/src/tools/spec.rs` and `core/src/tools/code_mode/mod.rs`
to use the extracted adapters from `codex-tools`
- removed the old `core/src/tools/code_mode_description.rs` shim and its
test file from `codex-core`
- added the `codex-code-mode` dependency to `codex-tools`, updated
`Cargo.lock`, and refreshed the `codex-tools` README to reflect the
expanded boundary
## Test Plan
- `cargo test -p codex-tools`
- `CARGO_TARGET_DIR=/tmp/codex-core-code-mode-adapters cargo test -p

## Why
The `plugin/list` force-sync path can race app-server startup's curated
plugin cache refresh.
Startup was capturing the configured curated plugin IDs from the initial
config snapshot. If `plugin/list` with `forceRemoteSync` removed curated
plugin entries from `config.toml` while that background refresh was
still in flight, the startup task could recreate cache directories for
plugins that had just been uninstalled.
That leaves the `plugin/list` response logically correct but the on-disk
cache stale, which matches the flaky Ubuntu arm failure seen in
`codex-app-server::all
suite::v2::plugin_list::plugin_list_force_remote_sync_reconciles_curated_plugin_state`
while validating [#16047](https://github.com/openai/codex/pull/16047).
## What
- change `codex-rs/core/src/plugins/manager.rs` so startup curated-repo
refresh rereads the current user `config.toml` before deciding which
curated plugin cache entries to refresh
- factor the configured-plugin parsing so the same logic can be reused
from either the config layer stack or the persisted user config value
- add a regression test that verifies curated plugin IDs are read from
the latest user config state before cache refresh runs
## Testing
- `cargo test -p codex-core
configured_curated_plugin_ids_from_codex_home_reads_latest_user_config
-- --nocapture`
- `cargo test -p codex-app-server
suite::v2::plugin_list::plugin_list_force_remote_sync_reconciles_curated_plugin_state
-- --nocapture`
- `just argument-comment-lint`
## Why
This continues the `codex-tools` migration by moving another passive
tool-spec layer out of `codex-core`.
After `ToolSpec` moved into `codex-tools`, `codex-core` still owned
`ConfiguredToolSpec` and `create_tools_json_for_responses_api()`. Both
are data-model and serialization helpers rather than runtime
orchestration, so keeping them in `core/src/tools/registry.rs` and
`core/src/tools/spec.rs` left passive tool-definition code coupled to
`codex-core` longer than necessary.
## What changed
- moved `ConfiguredToolSpec` into `codex-rs/tools/src/tool_spec.rs`
- moved `create_tools_json_for_responses_api()` into
`codex-rs/tools/src/tool_spec.rs`
- re-exported the new surface from `codex-rs/tools/src/lib.rs`, which
remains exports-only
- updated `core/src/client.rs`, `core/src/tools/registry.rs`, and
`core/src/tools/router.rs` to consume the extracted types and serializer
from `codex-tools`
- moved the tool-list serialization test into
`codex-rs/tools/src/tool_spec_tests.rs`
- added focused unit coverage for `ConfiguredToolSpec::name()`
- simplified `core/src/tools/spec_tests.rs` to use the extracted
`ConfiguredToolSpec::name()` directly and removed the now-redundant
local `tool_name()` helper
- updated `codex-rs/tools/README.md` so the crate boundary reflects the
newly extracted tool-spec wrapper and serialization helper
## Test plan

- `CARGO_TARGET_DIR=/tmp/codex-core-configured-spec cargo test -p

## Why
This continues the `codex-tools` migration by moving another passive
tool-definition layer out of `codex-core`.
After `ResponsesApiTool` and the lower-level schema adapters moved into
`codex-tools`, `core/src/client_common.rs` was still owning `ToolSpec`
and the web-search request wire types even though they are serialized
data models rather than runtime orchestration. Keeping those types in
`codex-core` makes the crate boundary look smaller than it really is and
leaves non-runtime tool-shape code coupled to core.
## What changed
- moved `ToolSpec`, `ResponsesApiWebSearchFilters`, and
`ResponsesApiWebSearchUserLocation` into
`codex-rs/tools/src/tool_spec.rs`
- added focused unit tests in `codex-rs/tools/src/tool_spec_tests.rs`
for:
- `ToolSpec::name()`
- web-search config conversions
- `ToolSpec` serialization for `web_search` and `tool_search`
- kept `codex-rs/tools/src/lib.rs` exports-only by re-exporting the new
module from `lib.rs`
- reduced `core/src/client_common.rs` to a compatibility shim that
re-exports the extracted tool-spec types for current core call sites
- updated `core/src/tools/spec_tests.rs` to consume the extracted
web-search types directly from `codex-tools`
- updated `codex-rs/tools/README.md` so the crate contract reflects that
`codex-tools` now owns the passive tool-spec request models in addition
to the lower-level Responses API structs
## Test plan
- `cargo test -p codex-tools`
- `cargo test -p codex-core --lib tools::spec::`
- `cargo test -p codex-core --lib client_common::`
- `just fix -p codex-tools -p codex-core`

## Summary
- remove protocol and core support for discovering and listing custom
prompts
- simplify the TUI slash-command flow and command popup to built-in
commands only
- delete obsolete custom prompt tests, helpers, and docs references
- clean up downstream event handling for the removed protocol events
## Why
`argument-comment-lint` had become a PR bottleneck because the repo-wide
lane was still effectively running a `cargo dylint`-style flow across
the workspace instead of reusing Bazel's Rust dependency graph. That
kept the lint enforced, but it threw away the main benefit of moving
this job under Bazel in the first place: metadata reuse and cacheable
per-target analysis in the same shape as Clippy.
This change moves the repo-wide lint onto a native Bazel Rust aspect so
Linux and macOS can lint `codex-rs` without rebuilding the world
crate-by-crate through the wrapper path.
## What Changed
- add a nightly Rust toolchain with `rustc-dev` for Bazel and a
dedicated crate-universe repo for `tools/argument-comment-lint`
- add `tools/argument-comment-lint/driver.rs` and
`tools/argument-comment-lint/lint_aspect.bzl` so Bazel can run the lint
as a custom `rustc_driver`
- switch repo-wide `just argument-comment-lint` and the Linux/macOS
`rust-ci` lanes to `bazel build --config=argument-comment-lint
//codex-rs/...`
- keep the Python/DotSlash wrappers as the package-scoped fallback path
and as the current Windows CI path
- gate the Dylint entrypoint behind a `bazel_native` feature so the
Bazel-native library avoids the `dylint_*` packaging stack
- update the aspect runtime environment so the driver can locate
`rustc_driver` correctly under remote execution
- keep the dedicated `tools/argument-comment-lint` package tests and
wrapper unit tests in CI so the source and packaged entrypoints remain
covered
## Verification
- `python3 -m unittest discover -s tools/argument-comment-lint -p
'test_*.py'`
- `cargo test` in `tools/argument-comment-lint`
- `bazel build
//tools/argument-comment-lint:argument-comment-lint-driver
--@rules_rust//rust/toolchain/channel=nightly`
- `bazel build --config=argument-comment-lint
//codex-rs/utils/path-utils:all`
- `bazel build --config=argument-comment-lint
//codex-rs/rollout:rollout`

This is a follow-up to https://github.com/openai/codex/pull/15922. That
previous PR deleted the old `tui` directory and left the new
`tui_app_server` directory in place. This PR renames `tui_app_server` to
`tui` and fixes up all references.
## Summary
- Moves status surface refresh (`refresh_status_surfaces` /
`refresh_status_line`) from `App` event handlers into `ChatWidget`
setters via a new `refresh_model_dependent_surfaces()` method
- Ensures model-dependent UI stays in sync whenever collaboration mode,
model, or reasoning effort changes, including the footer and terminal
title in both `tui` and `tui_app_server`
- Applies the fix to both `tui` and `tui_app_server` widgets
#15961
## Test plan
- [x] Added snapshot test
`status_line_model_with_reasoning_plan_mode_footer` verifying footer
renders correctly in plan mode
- [x] Added
`terminal_title_model_updates_on_model_change_without_manual_refresh` in
`tui_app_server`
- [ ] Verify switching collaboration modes updates the footer in real
TUI
- [ ] Verify model/reasoning effort changes reflect in the status bar
and terminal title

## Why
The initial `argument-comment-lint` rollout left Windows on
default-target coverage because there were still Windows-only callsites
failing under `--all-targets`. This follow-up cleans up those remaining
Windows-specific violations so the Windows CI lane can enforce the same
stricter coverage, leaving Linux as the remaining platform-specific
follow-up.
## What changed
- switched the Windows `rust-ci` argument-comment-lint step back to the
default wrapper invocation so it runs full-target coverage again
- added the required `/*param_name*/` annotations at Windows-gated
literal callsites in:
- `codex-rs/windows-sandbox-rs/src/lib.rs`
- `codex-rs/windows-sandbox-rs/src/elevated_impl.rs`
- `codex-rs/tui_app_server/src/multi_agents.rs`
- `codex-rs/network-proxy/src/proxy.rs`
## Validation
- Windows `argument comment lint` CI on this PR
## Why
`//codex-rs/shell-command:shell-command-unit-tests` became a real
bottleneck in the Windows Bazel lane because repeated calls to
`is_safe_command_windows()` were starting a fresh PowerShell parser
process for every `powershell.exe -Command ...` assertion.
PR #16056 was motivated by that same bottleneck, but its test-only
shortcut was the wrong layer to optimize because it weakened the
end-to-end guarantee that our runtime path really asks PowerShell to
parse the command the way we expect.
This PR attacks the actual cost center instead: it keeps the real
PowerShell parser in the loop, but turns that parser into a long-lived
helper process so both tests and the runtime safe-command path can reuse
it across many requests.
## What Changed
- add `shell-command/src/command_safety/powershell_parser.rs`, which
keeps one mutex-protected parser process per PowerShell executable path
and speaks a simple JSON-over-stdio request/response protocol
- turn `shell-command/src/command_safety/powershell_parser.ps1` into a
long-running parser server with comments explaining the protocol, the
AST-shape restrictions, and why unsupported constructs are rejected
conservatively
- keep request ids and a one-time respawn path so a dead or
desynchronized cached child fails closed instead of silently returning
mixed parser output
- preserve separate parser processes for `powershell.exe` and
`pwsh.exe`, since they do not accept the same language surface
- avoid a direct `PipelineChainAst` type reference in the PowerShell
script so the parser service still runs under Windows PowerShell 5.1 as
well as newer `pwsh`
- make `shell-command/src/command_safety/windows_safe_commands.rs`
delegate to the new parser utility instead of spawning a fresh
PowerShell process for every parse
- add a Windows-only unit test that exercises multiple sequential
requests against the same parser process
## Testing
- adds a Windows-only parser-reuse unit test in `powershell_parser.rs`
- the main end-to-end verification for this change is the Windows CI
lane, because the new service depends on real `powershell.exe` /
`pwsh.exe` behavior
# Summary
Claude Code supports a useful prompt-plus-stdin workflow:
```bash
echo "complex input..." | claude -p "summarize concisely"
```
Codex previously did not support the equivalent `codex exec` form. While
`codex exec` could read the prompt from stdin, it could not combine
piped input with an explicit prompt argument.
This change adds that missing workflow:
```bash
echo "complex input..." | codex exec "summarize concisely"
```
With this change, when `codex exec` receives both a positional prompt
and piped stdin, the prompt remains the instruction and stdin is passed
along as structured `<stdin>...</stdin>` context.
Example:
```bash
curl https://jsonplaceholder.typicode.com/comments \
| ./target/debug/codex exec --skip-git-repo-check "format the top 20 items into a markdown table" \
> table.md
```
This PR also adds regression coverage for:
- prompt argument + piped stdin
- legacy stdin-as-prompt behavior
- `codex exec -` forced-stdin behavior
- empty-stdin error cases

## Why
`argument-comment-lint` was green in CI even though the repo still had
many uncommented literal arguments. The main gap was target coverage:
the repo wrapper did not force Cargo to inspect test-only call sites, so
examples like the `latest_session_lookup_params(true, ...)` tests in
`codex-rs/tui_app_server/src/lib.rs` never entered the blocking CI path.
This change cleans up the existing backlog, makes the default repo lint
path cover all Cargo targets, and starts rolling that stricter CI
enforcement out on the platform where it is currently validated.
## What changed
- mechanically fixed existing `argument-comment-lint` violations across
the `codex-rs` workspace, including tests, examples, and benches
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` and
`tools/argument-comment-lint/run.sh` so non-`--fix` runs default to
`--all-targets` unless the caller explicitly narrows the target set
- fixed both wrappers so forwarded cargo arguments after `--` are
preserved with a single separator
- documented the new default behavior in
`tools/argument-comment-lint/README.md`
- updated `rust-ci` so the macOS lint lane keeps the plain wrapper
invocation and therefore enforces `--all-targets`, while Linux and
Windows temporarily pass `-- --lib --bins`
That temporary CI split keeps the stricter all-targets check where it is
already cleaned up, while leaving room to finish the remaining Linux-
and Windows-specific target-gated cleanup before enabling
`--all-targets` on those runners. The Linux and Windows failures on the
intermediate revision were caused by the wrapper forwarding bug, not by
additional lint findings in those lanes.
## Validation
- `bash -n tools/argument-comment-lint/run.sh`
- `bash -n tools/argument-comment-lint/run-prebuilt-linter.sh`
- shell-level wrapper forwarding check for `-- --lib --bins`
- shell-level wrapper forwarding check for `-- --tests`
- `just argument-comment-lint`
- `cargo test` in `tools/argument-comment-lint`
- `cargo test -p codex-terminal-detection`
## Follow-up
- Clean up remaining Linux-only target-gated callsites, then switch the
Linux lint lane back to the plain wrapper invocation.
- Clean up remaining Windows-only target-gated callsites, then switch
the Windows lint lane back to the plain wrapper invocation.
Addresses #15992
The app-server TUI was treating tracked agent threads as closed based on
listener-task bookkeeping that does not reflect live thread state during
normal thread switching. That caused the `/agent` picker to gray out
live agents and could show a false "Agent thread ... is closed" replay
message after switching branches.
This PR fixes the picker refresh path to query the app server for each
tracked thread and derive closed vs loaded state from `thread/read`
status, while preserving cached agent metadata for replay-only threads.
Addresses #16049
`codex resume <name>` and `/resume <name>` could fail in the app-server
TUI path because name lookup pre-filtered `thread/list` with the backend
`search_term`, but saved thread names are hydrated after listing and are
not part of that search index. Resolve names by scanning listed threads
client-side instead, and add a regression test for saved sessions whose
rollout title does not match the thread name.
This is the part 1 of 2 PRs that will delete the `tui` /
`tui_app_server` split. This part simply deletes the existing `tui`
directory and marks the `tui_app_server` feature flag as removed. I left
the `tui_app_server` feature flag in place for now so its presence
doesn't result in an error. It is simply ignored.
Part 2 will rename the `tui_app_server` directory `tui`. I did this as
two parts to reduce visible code churn.
apply_patch sometimes provides additional parent dir as a writable root
when it is already writable. This is mostly a no-op on Mac/Linux but
causes actual ACL churn on Windows that is best avoided. We are also
seeing some actual failures with these ACLs in the wild, which I haven't
fully tracked down, but it's safe/best to avoid doing it altogether.
- [x] Auto / unspecified approval mode: read-only tools now skip before
guardian routing.
- [x] Approve / always-allow mode: read-only tools still skip, now via
the shared early return.
- [x] Prompt mode: read-only tools no longer skip; they continue to
approval.
Addresses #16019
`tui_app_server` renders completed assistant messages from item
notifications, but it only updated `/copy` state from `turn/completed`.
After the app-server migration, turn completion no longer repeats the
final assistant text, so `/copy` could stay unavailable even after the
first normal response.
This PR track the last completed final-answer agent message during an
active app-server turn and promote it into the `/copy` cache when the
turn completes. This restores the pre-migration behavior without
changing rollback handling.
Addresses #15984
HookStarted/HookCompleted notifications were being translated through a
fragile JSON bridge, so hook status/output never reached the renderer.
Early hook notifications could also be dropped during session refresh
before replay.
This PR fixes `tui_app_server` by mapping app-server hook notifications
into TUI hook events explicitly and preserving buffered hook
notifications across refresh, so cold-start and resumed sessions render
the same hook UI as the legacy TUI.
## Why
The previous extraction steps moved shared tool-schema parsing into
`codex-tools`, but `codex-core` still owned the generic Responses API
tool models and the last adapter layer that turned parsed tool
definitions into `ResponsesApiTool` values.
That left `core/src/tools/spec.rs` and `core/src/client_common.rs`
holding a chunk of tool-shaping code that does not need session state,
runtime plumbing, or any other `codex-core`-specific dependency. As a
result, `codex-tools` owned the parsed tool definition, but `codex-core`
still owned the generic wire model that those definitions are converted
into.
This change moves that boundary one step further. `codex-tools` now owns
the reusable Responses/tool wire structs and the shared conversion
helpers for dynamic tools, MCP tools, and deferred MCP aliases.
`codex-core` continues to own `ToolSpec` orchestration and the remaining
web-search-specific request shapes.
## What changed
- added `tools/src/responses_api.rs` to own `ResponsesApiTool`,
`FreeformTool`, `ToolSearchOutputTool`, namespace output types, and the
shared `ToolDefinition -> ResponsesApiTool` adapter helpers
- added `tools/src/responses_api_tests.rs` for deferred-loading
behavior, adapter coverage, and namespace serialization coverage
- rewired `core/src/tools/spec.rs` to use the extracted dynamic/MCP
adapter helpers instead of defining those conversions locally
- rewired `core/src/tools/handlers/tool_search.rs` to use the extracted
deferred MCP adapter and namespace output types directly
- slimmed `core/src/client_common.rs` so it now keeps `ToolSpec` and the
web-search-specific wire types, while reusing the extracted tool models
from `codex-tools`
- moved the extracted seam tests out of `core` and updated
`codex-rs/tools/README.md` plus `tools/src/lib.rs` to reflect the
expanded `codex-tools` boundary
## Test plan

## Summary
- add `self_serve_business_usage_based` and `enterprise_cbp_usage_based`
to the public/internal plan enums and regenerate the app-server + Python
SDK artifacts
- map both plans through JWT login and backend rate-limit payloads, then
bucket them with the existing Team/Business entitlement behavior in
cloud requirements, usage-limit copy, tooltips, and status display
- keep the earlier display-label remap commit on this branch so the new
Team-like and Business-like plans render consistently in the UI

1. Keep curated plugin staging directories under TempDir ownership until
activation succeeds, so failed git/HTTP sync attempts do not leak
plugins-clone-*.
2. Best-effort clean up stale plugins-clone-* directories before
creating a new staged repo, using a conservative age threshold.
3. Emit OTEL counters for curated plugin startup sync transport attempts
and final outcome across git and HTTP paths.
#15999 introduced a Windows-only `\r\n` mismatch in review-exit template
handling. This PR normalizes those template newlines and separates that
fix from [#16014](https://github.com/openai/codex/pull/16014) so it can
be reviewed independently.
## Why
This continues the `codex-tools` migration by moving one more piece of
generic tool-definition bookkeeping out of `codex-core`.
The earlier extraction steps moved shared schema parsing into
`codex-tools`, but `core/src/tools/spec.rs` still had to supply tool
names separately and perform ad hoc rewrites for deferred MCP aliases.
That meant the crate boundary was still awkward: the parsed shape coming
back from `codex-tools` was missing part of the definition that
`codex-core` ultimately needs to assemble a `ResponsesApiTool`.
This change introduces a named `ToolDefinition` in `codex-tools` so both
MCP tools and dynamic tools cross the crate boundary in the same
reusable model. `codex-core` still owns the final `ResponsesApiTool`
assembly, but less of the generic tool-definition shaping logic stays
behind in `core`.
## What changed
- replaced `ParsedToolDefinition` with a named `ToolDefinition` in
`codex-rs/tools/src/tool_definition.rs`
- added `codex-rs/tools/src/tool_definition_tests.rs` for `renamed()`
and `into_deferred()`
- updated `parse_dynamic_tool()` and `parse_mcp_tool()` to return
`ToolDefinition`
- simplified `codex-rs/core/src/tools/spec.rs` so it adapts
`ToolDefinition` into `ResponsesApiTool` instead of rewriting names and
deferred fields inline
- updated parser tests and `codex-rs/tools/README.md` to reflect the
named tool-definition model
## Test plan
- `cargo test -p codex-tools`
- `cargo test -p codex-core --lib tools::spec::`
## Why
`bazel.yml` already builds and tests the Bazel graph, but `rust-ci.yml`
still runs `cargo clippy` separately. This PR starts the transition to a
Bazel-backed lint lane for `codex-rs` so we can eventually replace the
duplicate Rust build, test, and lint work with Bazel while explicitly
keeping the V8 Bazel path out of scope for now.
To make that lane practical, the workflow also needs to look like the
Bazel job we already trust. That means sharing the common Bazel setup
and invocation logic instead of hand-copying it, and covering the arm64
macOS path in addition to Linux.
Landing the workflow green also required fixing the first lint findings
that Bazel surfaced and adding the matching local entrypoint.
## What changed
- add a reusable `build:clippy` config to `.bazelrc` and export
`codex-rs/clippy.toml` from `codex-rs/BUILD.bazel` so Bazel can run the
repository's existing Clippy policy
- add `just bazel-clippy` so the local developer entrypoint matches the
new CI lane
- extend `.github/workflows/bazel.yml` with a dedicated Bazel clippy job
for `codex-rs`, scoped to `//codex-rs/... -//codex-rs/v8-poc:all`
- run that clippy job on Linux x64 and arm64 macOS
- factor the shared Bazel workflow setup into
`.github/actions/setup-bazel-ci/action.yml` and the shared Bazel
invocation logic into `.github/scripts/run-bazel-ci.sh` so the clippy
and build/test jobs stay aligned
- fix the first Bazel-clippy findings needed to keep the lane green,
including the cross-target `cmsghdr::cmsg_len` normalization in
`codex-rs/shell-escalation/src/unix/socket.rs` and the no-`voice-input`
dead-code warnings in `codex-rs/tui` and `codex-rs/tui_app_server`
## Verification
- `just bazel-clippy`
- `RUNNER_OS=macOS ./.github/scripts/run-bazel-ci.sh -- build
--config=clippy --build_metadata=COMMIT_SHA=local-check
--build_metadata=TAG_job=clippy -- //codex-rs/...
-//codex-rs/v8-poc:all`
- `bazel build --config=clippy
//codex-rs/shell-escalation:shell-escalation`
- `CARGO_TARGET_DIR=/tmp/codex4-shell-escalation-test cargo test -p
codex-shell-escalation`
- `ruby -e 'require "yaml";
YAML.load_file(".github/workflows/bazel.yml");
YAML.load_file(".github/actions/setup-bazel-ci/action.yml")'`
## Notes
- `CARGO_TARGET_DIR=/tmp/codex4-tui-app-server-test cargo test -p
codex-tui-app-server` still hits existing guardian-approvals test and
snapshot failures unrelated to this PR's Bazel-clippy changes.

## Why
`codex-tools` already owned the shared JSON schema parser and the MCP
tool schema adapter, but `core/src/tools/spec.rs` still parsed dynamic
tools directly.
That left the tool-schema boundary split in two different ways:
- MCP tools flowed through `codex-tools`, while dynamic tools were still
parsed in `codex-core`
- the extracted dynamic-tool path initially introduced a
dynamic-specific parsed shape even though `codex-tools` already had very
similar MCP adapter output
This change finishes that extraction boundary in one step. `codex-core`
still owns `ResponsesApiTool` assembly, but both MCP tools and dynamic
tools now enter that layer through `codex-tools` using the same parsed
tool-definition shape.
## What changed
- added `tools/src/dynamic_tool.rs` and sibling
`tools/src/dynamic_tool_tests.rs`
- introduced `parse_dynamic_tool()` in `codex-tools` and switched
`core/src/tools/spec.rs` to use it for dynamic tools
- added `tools/src/parsed_tool_definition.rs` so both MCP and dynamic
adapters return the same `ParsedToolDefinition`
- updated `core/src/tools/spec.rs` to build `ResponsesApiTool` through a
shared local adapter helper instead of separate MCP and dynamic assembly
paths
- expanded `core/src/tools/spec_tests.rs` so the dynamic-tool adapter
test asserts the full converted `ResponsesApiTool`, including
`defer_loading`
- updated `codex-rs/tools/README.md` to reflect the shared parsed
tool-definition boundary
## Test plan
- `cargo test -p codex-tools`
- `cargo test -p codex-core --lib tools::spec::`

## Summary
- split the joined `PATH` before running system `bwrap` lookup
- keep the existing workspace-local `bwrap` skip behavior intact
- add regression tests that exercise real multi-entry search paths
## Why
The PATH-based lookup added in #15791 still wrapped the raw `PATH`
environment value as a single `PathBuf` before passing it through
`join_paths()`. On Unix, a normal multi-entry `PATH` contains `:`, so
that wrapper path is invalid as one path element and the lookup returns
`None`.
That made Codex behave as if no system `bwrap` was installed even when
`bwrap` was available on `PATH`, which is what users in #15340 were
still hitting on `0.117.0-alpha.25`.
## Impact
System `bwrap` discovery now works with normal multi-entry `PATH` values
instead of silently falling back to the vendored binary.
Fixes#15340.
## Validation
- `just fmt`
- `cargo test -p codex-sandboxing`
- `cargo test -p codex-linux-sandbox`
- `just fix -p codex-sandboxing`
- `just argument-comment-lint`
