## Why
The previous `codex-tools` migration steps moved the shared schema
models, local-host specs, collaboration specs, and related adapters out
of `codex-core`, but `core/src/tools/spec.rs` still contained a grab bag
of pure utility tool builders. Those specs do not need session state or
handler logic; they only describe wire shapes for tools that
`codex-core` already knows how to execute.
Moving that remaining low-coupling layer into `codex-tools` keeps the
migration moving in meaningful chunks and trims another large block of
passive tool-spec construction out of `codex-core` without touching the
runtime-coupled handlers.
## What changed
- extended `codex-tools` to own the pure spec builders for:
- code-mode `exec` / `wait`
- `js_repl` / `js_repl_reset`
- MCP resource tools `list_mcp_resources`,
`list_mcp_resource_templates`, and `read_mcp_resource`
- utility tools `list_dir` and `test_sync_tool`
- split those builders across small module files with sibling
`*_tests.rs` coverage, keeping `src/lib.rs` exports-only
- rewired `core/src/tools/spec.rs` to call the extracted builders and
deleted the duplicated core-local implementations
- moved the direct JS REPL grammar seam test out of
`core/src/tools/spec_tests.rs` so it now lives with the extracted
implementation in `codex-tools`
- updated `codex-rs/tools/README.md` so the documented crate boundary
matches the new utility-spec surface

## Why
The recent `codex-tools` migration steps have moved shared tool models
and low-coupling spec helpers out of `codex-core`, but
`core/src/tools/spec.rs` still owned a large block of pure
collaboration-tool spec construction. Those builders do not need session
state or runtime behavior; they only need a small amount of core-owned
configuration injected at the seam.
Moving that cohesive slice into `codex-tools` makes the crate boundary
more honest and removes a substantial amount of passive tool-spec logic
from `codex-core` without trying to move the runtime-coupled multi-agent
handlers at the same time.
## What changed
- added `agent_tool.rs`, `request_user_input_tool.rs`, and
`agent_job_tool.rs` to `codex-tools`, with sibling `*_tests.rs` coverage
and an exports-only `lib.rs`
- moved the pure `ToolSpec` builders for:
- collaboration tools such as `spawn_agent`, `send_input`,
`send_message`, `assign_task`, `resume_agent`, `wait_agent`,
`list_agents`, and `close_agent`
- `request_user_input`
- agent-job specs `spawn_agents_on_csv` and `report_agent_job_result`
- rewired `core/src/tools/spec.rs` to call the extracted builders while
still supplying the core-owned inputs, such as spawn-agent role
descriptions and wait timeout bounds
- updated the `core/src/tools/spec.rs` seam tests to build expected
collaboration specs through `codex-tools`
- updated `codex-rs/tools/README.md` so the crate documentation reflects
the broader collaboration-tool boundary

Preserve the collab transcript fixtures and current TUI style rules after rebasing onto the refreshed tui_app_server codebase.
Co-authored-by: Codex <noreply@openai.com>
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

## 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

## 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`

## 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

## 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
