pakrym-oai 83decfa300 [codex] Remove unused legacy shell tools (#22246 )

## Why

Recent session history showed no active use of the raw `shell`,
`local_shell`, or `container.exec` execution surfaces. Keeping those
handlers/specs wired into core leaves duplicate shell execution paths
alongside the supported `shell_command` and unified exec tools.

## What changed

- Removed the raw `shell` handler/spec and its `ShellToolCallParams`
protocol helper.
- Removed the legacy `local_shell` and `container.exec` handler/spec
plumbing while preserving persisted-history compatibility for old
response items.
- Normalized model/config `default` and `local` shell selections to
`shell_command`.
- Pruned tests that exercised removed raw-shell/local-shell/apply-patch
variants and kept coverage on `shell_command`, unified exec, and
freeform `apply_patch`.

## Verification

- `git diff --check`
- `cargo test -p codex-protocol`
- `cargo test -p codex-tools`
- `cargo test -p codex-core tools::handlers::shell`
- `cargo test -p codex-core tools::spec`
- `cargo test -p codex-core tools::router`
- `cargo test -p codex-core
active_call_preserves_triggering_command_context`
- `cargo test -p codex-core guardian_tests`
- `cargo test -p codex-core --test all shell_serialization`
- `cargo test -p codex-core --test all apply_patch_cli`
- `cargo test -p codex-core --test all shell_command_`
- `cargo test -p codex-core --test all local_shell`
- `cargo test -p codex-core --test all otel::`
- `cargo test -p codex-core --test all hooks::`
- `just fix -p codex-core`
- `just fix -p codex-tools`

codex-tools

codex-tools is the shared support crate for building, adapting, planning, and executing model-visible tool sets outside codex-core.

Today this crate owns the host-facing tool models and helpers that no longer need to live in core/src/tools/spec.rs or core/src/client_common.rs:

aggregate host models such as ToolSpec, ConfiguredToolSpec, LoadableToolSpec, ResponsesApiNamespace, and ResponsesApiNamespaceTool
host config and discovery models used while assembling tool sets, including ToolsConfig, discoverable-tool models, and request-plugin-install helpers
host adapters such as schema sanitization, MCP/dynamic conversion, code-mode augmentation, and image-detail normalization
shared executable-tool contracts such as ToolExecutor, ToolCall, and ToolOutput

That extraction is the first step in a longer migration. The goal is not to move all of core/src/tools into this crate in one shot. Instead, the plan is to peel off reusable pieces in reviewable increments while keeping compatibility-sensitive orchestration in codex-core until the surrounding boundaries are ready.

Vision

Over time, this crate should hold host-side tool machinery that is shared by multiple consumers, for example:

host-visible aggregate tool models
tool-set planning and discovery helpers
MCP and dynamic-tool adaptation into Responses API shapes
code-mode compatibility shims that do not depend on codex-core
other narrowly scoped host utilities that multiple crates need

The corresponding non-goals are just as important:

do not move codex-core orchestration here prematurely
do not pull Session / TurnContext / approval flow / runtime execution logic into this crate unless those dependencies have first been split into stable shared interfaces
do not turn this crate into a grab-bag for unrelated helper code

Migration approach

The expected migration shape is:

Keep extension-owned executable-tool authoring in codex-extension-api.
Move host-side planning/adaptation helpers here when they no longer need to stay coupled to codex-core.
Leave compatibility-sensitive adapters in codex-core while downstream call sites are updated.
Only extract higher-level host infrastructure after the crate boundaries are clear and independently testable.

Crate conventions

This crate should start with stricter structure than core/src/tools so it stays easy to grow:

src/lib.rs should remain exports-only.
Business logic should live in named module files such as foo.rs.
Unit tests for foo.rs should live in a sibling foo_tests.rs.
The implementation file should wire tests with:

#[cfg(test)]
#[path = "foo_tests.rs"]
mod tests;

If this crate starts accumulating code that needs runtime state from codex-core, that is a sign to revisit the extraction boundary before adding more here.
