## Summary
- move `plugin/list` from the shared `config` read queue onto a
dedicated `plugin-list` shared-read queue
- move `plugin/read` onto that same dedicated shared-read queue as well
- keep the existing scheduler behavior unchanged
- allow plugin list/read operations to proceed independently of
config-family writes, accepting temporary stale or transient read errors
during concurrent mutations
## Validation
- `just fmt`
- `cargo test -p codex-app-server-protocol`
## Why
Extension tools were split across two public runtime contracts:
`codex-tool-api` exposed `ToolBundle` plus its own call/spec/error
types, while core native tools used `codex_tools::ToolExecutor`. That
made contributed tool specs and execution behavior easy to drift apart
and added another crate boundary for what should be one executable-tool
seam.
This PR makes `ToolExecutor` the single runtime contract and keeps
extension-specific pinning in `codex-extension-api`.
## Remaining todo
https://github.com/openai/codex/pull/22369/changes#diff-b935ea8245c3ce568a30cff660175fa6390b66b872ae409e1e2e965738250741R5
Either generic `Invocation` or sub-extract the `ToolCall` and clean
`ToolInvocation`
## What changed
- Removed the `codex-tool-api` workspace crate and its dependencies from
core and `codex-extension-api`.
- Made `codex_tools::ToolExecutor` object-safe with `async_trait` so
extension contributors can return a dyn executor.
- Added the extension-facing aliases under
`ext/extension-api/src/contributors/tools.rs`, including
`ExtensionToolExecutor = dyn ToolExecutor<ToolCall, Output =
ExtensionToolOutput>`.
- Changed `ToolContributor::tools` to return extension executors
directly instead of `ToolBundle`s.
- Updated core’s extension tool handler/registry/router path to adapt
those extension executors into the existing native `ToolInvocation`
runtime path.
- Added focused coverage for extension tools being registered,
model-visible, dispatchable, and not replacing built-in tools.
## Verification
- `cargo test -p codex-tools`
- `cargo test -p codex-extension-api`
## Why
Codex still models model-visible tools and executable behavior largely
inside `codex-core`, which makes it harder to evolve the tool system
toward a single reusable abstraction for built-ins, MCP-backed tools,
dynamic tools, and later tools injected from outside core.
This PR takes the next incremental step in that direction by moving the
common execution-facing pieces out of core and separating them from
core-only orchestration. The intent is to let shared tool abstractions
improve in one place, while `codex-core` keeps the parts that are still
inherently host-specific today, such as `ToolInvocation`, dispatch
wiring, and hook integration.
This PR is mostly moving things around. The only interesting piece is
this abstraction:
https://github.com/openai/codex/pull/22359/changes#diff-81af519002548ba51ed102bdaaf77e081d40a1e73a6e5f9b104bbbc96a6f1b3dR13
## What changed
- Added `codex_tools::ToolExecutor<Invocation>` as the shared execution
trait for model-visible tools.
- Moved the reusable execution support types from `codex-core` into
`codex-tools`:
- `FunctionCallError`
- `ToolPayload`
- `ToolOutput`
- Refactored core tool implementations so that execution behavior lives
on `ToolExecutor<ToolInvocation>`, while `ToolHandler` remains the
core-local extension point for hook payloads, telemetry tags, diff
consumers, and other orchestration concerns.
- Kept the registry and dispatch flow behaviorally unchanged while
making the shared/extracted boundary explicit across built-in, MCP,
dynamic, extension-backed, shell, and multi-agent tool handlers.
## Verification
- `cargo test -p codex-tools`
- `just fix -p codex-tools`
- `just fix -p codex-core`
- `cargo test -p codex-core` progressed through the updated tool
surfaces and then hit the existing unrelated multi-agent stack overflow
in
`tools::handlers::multi_agents::tests::tool_handlers_cascade_close_and_resume_and_keep_explicitly_closed_subtrees_closed`.
## Why
`codex-extension-api` needs an approval hook that lets an installed
extension own a rendered approval-review prompt and produce the final
`ReviewDecision`. The prior interceptor stub only exposed a yes/no claim
and did not model the review result itself, which left the host with the
missing half of the control flow.
## What changed
- Replaces `ApprovalInterceptorContributor` with
[`ApprovalReviewContributor`](c49d17531e/codex-rs/ext/extension-api/src/contributors.rs (L43-L55)),
which may claim a rendered prompt and return an async `ReviewDecision`.
- Re-exports the new contributor and future types from `extension-api`.
- Adds registry support through `approval_review_contributor(...)` plus
[`ExtensionRegistry::approval_review(...)`](c49d17531e/codex-rs/ext/extension-api/src/registry.rs (L90-L101)),
which returns the first installed contributor that claims the prompt.
## Summary
- move the `view_image` sandbox filesystem-read unit test onto a
temporary cwd
- keep the turn cwd and selected turn environment cwd aligned inside the
test
- avoid leaving `core/image.png` behind in the repo checkout after the
test runs
## Root cause
The test wrote `image.png` beneath `turn.cwd`, and the shared session
test helper defaults that cwd to the current repo directory when no
override is provided.
## Validation
- `just fmt`
- `cargo test -p codex-core
tools::handlers::view_image::tests::handle_passes_sandbox_context_for_local_filesystem_reads`
Adds plugin/share/checkout to turn a shared remote plugin into a local
working copy under ~/plugins/<name>.
Registers the copy in the managed personal marketplace and records the
remote-to-local mapping for later share/save flows.

# Why
Hook trust happens through the TUI in `/hooks` so it can block
non-interactive use cases. This flag will allow users that are using
codex headlessly to bypass hooks when they want to.
# What
This adds one invocation-scoped escape hatch.
- the CLI flag sets a runtime-only `bypass_hook_trust` override; there
is no durable `config.toml` setting
- hook discovery still respects normal enablement, so explicitly
disabled hooks remain disabled
- we show a `--dangerously-bypass-hook-trust is enabled. Enabled hooks
may run without review for this invocation.` message on startup so
accidental use is visible in both interactive and exec flows
This keeps “enabled” and “trusted” as separate concepts in the normal
path, while giving CI/E2E callers a stable way to opt into the
exceptional path when they already control the hook set.
# Why
Linked worktrees currently load their own project hook declarations, so
the same repo can present different hook definitions depending on which
checkout is active. https://github.com/openai/codex/pull/21762 tried to
share trust by giving matching worktree hooks a shared synthetic key,
but review pointed out that divergent worktree hook definitions would
then fight over one `trusted_hash`.
Instead of introducing a second trust model, this makes linked worktrees
use the root checkout as the single source of truth for project hook
declarations. Worktree-local project config can still diverge for
unrelated settings, but project hooks now keep one real source path and
one trust state per repo.
# What
- Teach project config loading to remember the matching root-checkout
`.codex/` folder for actual linked-worktree project layers.
- Keep ordinary project config sourced from the worktree, but replace
project hook declarations with the root checkout's matching layer before
hook discovery runs, including linked-worktree layers with `.codex/` but
no local `config.toml`.
- Make hook discovery use that authoritative hook folder for both
`hooks.json` and TOML hook source paths, so linked worktrees produce the
same hook key and trust state as the root checkout.
- Cover the linked-worktree path plus regressions for missing worktree
`config.toml` and nested non-worktree project roots.
## Why
`UnavailableDummyTools` kept synthetic placeholder tools alive for
historical tool calls whose backing MCP tool was no longer available.
That path adds stale model-visible tool specs and special routing at the
point where unavailable MCP calls should use ordinary current-tool
handling. This removes the runtime backfill instead of preserving a
second compatibility lane.
## Is it safe to remove?
The unavailable tools were added in #17853 after a CS issue when a
previously-called MCP tool failed to load and was omitted from the CS
spec. Now that we have tool search, I think this is resolved:
- API merges tools from previous TST output into effective tool set so
theyre always in CS spec
- if an MCP tool surfaced by TST later becomes unavailable, the model
can still call it and it will just return model-visible error
- both TST output and function call output are dropped on compaction so
model will not remember old calls to MCP post compaction
## What changed
- Delete unavailable-tool collection, placeholder handler, router/spec
plumbing, and obsolete placeholder coverage.
- Keep `features.unavailable_dummy_tools` as a removed no-op feature
tombstone so existing configs still parse cleanly.
- Add an integration-style `tool_search` regression test showing that a
deferred MCP tool surfaced through `tool_search` still routes through
MCP and returns a model-visible tool-call error rather than `unsupported
call`.
## Verification
- `cargo test -p codex-core tool_search`
## Why
`chatwidget.rs` is still carrying too many unrelated responsibilities in
one file. #22269 started a five-phase effort to move coherent behavior
domains into focused modules while keeping `chatwidget.rs` as the
composition layer.
This PR is phase 2 of that plan. It extracts the input and submission
flow as a mechanical move before the later protocol, popup/status, and
constructor/orchestration phases.
## What Changed
- Added `codex-rs/tui/src/chatwidget/input_flow.rs` for composer input
results, queued user-message draining, pending-input previews, and
mode-specific submission entry points.
- Added `codex-rs/tui/src/chatwidget/input_submission.rs` for
user-message construction/submission, shell prompt submission,
structured mention resolution, and blocked image draft restoration.
- Added `codex-rs/tui/src/chatwidget/input_restore.rs` for
initial-message submission, pending steer restoration after interrupts,
and thread input snapshot/restore behavior.
- Registered the new modules and removed the moved `ChatWidget` impl
methods from `codex-rs/tui/src/chatwidget.rs`.
## Follow-On Refactor Phases
The five-phase plan from #22269 is:
- Phase 1: mechanical helper and state moves. Completed in #22269.
- Phase 2: extract input and submission flow, including queued user
messages, shell prompt submission, pending steer restoration, and thread
input snapshot/restore behavior. This PR.
- Phase 3: extract protocol, replay, streaming, and tool lifecycle
handling, while preserving active-cell grouping, transcript
invalidation, interrupt deferral, and final-message separator behavior.
- Phase 4: extract settings, popups, and status surfaces, including
model/reasoning/collaboration/personality popups, permission prompts,
rate-limit UI, and connectors helpers.
- Phase 5: clean up the remaining constructor and orchestration code
once the larger behavior domains have moved out, leaving `chatwidget.rs`
as the composition layer.
## Why
Added support for UDS connections in `codex --remote`.
TUI also now connects to local app-server using UDS by default if it is
running and set to listen to UDS connection.
## What Changed
- Introduced `RemoteAppServerEndpoint` with `WebSocket` and `UnixSocket`
variants.
- Reused the existing JSON-RPC-over-WebSocket protocol over either a TCP
WebSocket stream or a UDS stream.
- Updated `codex --remote` to accept `ws://host:port`,
`wss://host:port`, `unix://`, and `unix://PATH`.
- Kept `--remote-auth-token-env` restricted to `wss://` and loopback
`ws://` remotes.
- Added a fast TUI startup probe for the default daemon socket, falling
back to the embedded app server when the daemon is absent or
unresponsive.
## Verification
- Manually verified that the updated remote flow works.
- Added coverage for UDS remote round trips, WebSocket auth headers,
auth-token transport policy, remote address parsing, and missing-daemon
fallback.
- Ran focused remote test coverage locally.
- Keep shared-with-me as the plugin/list request kind, but return
private plugins under workspace-shared-with-me-private.
- Add workspace-shared-with-me-unlisted for installed workspace plugins
with UNLISTED discoverability,
## Why
This builds on the handler-owned spec refactor by moving deferred
tool-search metadata to the same handlers that already own tool specs.
The registry builder no longer needs a separate prebuilt
`tool_search_entries` path; it can collect searchable entries from
deferred handlers directly.
## What changed
- Added `search_info()` to tool handlers and implemented it for MCP and
dynamic handlers.
- Reused handler `spec()` output when constructing tool-search entries,
adapting it into the deferred `LoadableToolSpec` shape expected by
`tool_search`.
- Simplified `build_tool_registry_builder(...)` so `tool_search`
registration is based on deferred handlers with search info.
- Removed the old standalone search-entry builders and now-unused
`codex-tools` discovery helper exports.
## Verification
- `cargo test -p codex-core tools::handlers::tool_search::tests:: --
--nocapture`
- `cargo test -p codex-core tools::spec_plan::tests::search_tool --
--nocapture`
- `cargo test -p codex-core tools::spec::tests:: -- --nocapture`
- `cargo test -p codex-core tools::spec_plan::tests:: -- --nocapture`
- `cargo test -p codex-tools`
- `just fix -p codex-core`
- `just fix -p codex-tools`
## Why
Code mode already builds the merged nested `ToolSpec`s that feed the
`exec` prompt. Keeping a separate `tool_namespaces` map in the planning
path duplicated that metadata and left extra wrapper plumbing in
`spec.rs`.
## What changed
- derive code-mode namespace descriptions from the merged
`ToolSpec::Namespace` entries before building the code-mode handlers
- extract `build_code_mode_handlers(...)` so the code-mode-specific
planning stays in one place
- remove `tool_namespaces` from `ToolRegistryBuildParams`
- delete the now-unused `McpToolPlanInputs` wrapper and related test
helper plumbing
## Testing
- `cargo test -p codex-core spec_plan`
