• Inject SKILL.md when it's explicitly mentioned. (#7763)

  1. Skills load once in core at session start; the cached outcome is
  reused across core and surfaced to TUI via SessionConfigured.
  2. TUI detects explicit skill selections, and core injects the matching
  SKILL.md content into the turn when a selected skill is present.

• refactoring with_escalated_permissions to use SandboxPermissions instead (#7750)

  helpful in the future if we want more granularity for requesting

• Fix: gracefully error out for unsupported images (#7478)

  Fix for #7459 
  ## What
  Since codex errors out for unsupported images, stop attempting to
  base64/attach them and instead emit a clear placeholder when the file
  isn’t a supported image MIME.
  
  ## Why
  Local uploads for unsupported formats (e.g., SVG/GIF/etc.) were
  dead-ending after decode failures because of the 400 retry loop. Users
  now get an explicit “cannot attach … unsupported image format …”
  response.
  
  ## How
  Replace the fallback read/encode path with MIME detection that bails out
  for non-image or unsupported image types, returning a consistent
  placeholder. Unreadable and invalid images still produce their existing
  error placeholders.

• Refactor execpolicy fallback evaluation (#7544)

  ## Refactor of the `execpolicy` crate
  
  To illustrate why we need this refactor, consider an agent attempting to
  run `apple | rm -rf ./`. Suppose `apple` is allowed by `execpolicy`.
  Before this PR, `execpolicy` would consider `apple` and `pear` and only
  render one rule match: `Allow`. We would skip any heuristics checks on
  `rm -rf ./` and immediately approve `apple | rm -rf ./` to run.
  
  To fix this, we now thread a `fallback` evaluation function into
  `execpolicy` that runs when no `execpolicy` rules match a given command.
  In our example, we would run `fallback` on `rm -rf ./` and prevent
  `apple | rm -rf ./` from being run without approval.

• [app-server & core] introduce new codex error code and v2 app-server error events (#6938)

  This PR does two things:
  1. populate a new `codex_error_code` protocol in error events sent from
  core to client;
  2. old v1 core events `codex/event/stream_error` and `codex/event/error`
  will now both become `error`. We also show codex error code for
  turncompleted -> error status.
  
  new events in app server test:

• [app-server] feat: v2 apply_patch approval flow (#6760)

  This PR adds the API V2 version of the apply_patch approval flow, which
  centers around `ThreadItem::FileChange`.
  
  This PR wires the new RPC (`item/fileChange/requestApproval`, V2 only)
  and related events (`item/started`, `item/completed` for
  `ThreadItem::FileChange`, which are emitted in both V1 and V2) through
  the app-server
  protocol. The new approval RPC is only sent when the user initiates a
  turn with the new `turn/start` API so we don't break backwards
  compatibility with VSCE.
  
  Similar to https://github.com/openai/codex/pull/6758, the approach I
  took was to make as few changes to the Codex core as possible,
  leveraging existing `EventMsg` core events, and translating those in
  app-server. I did have to add a few additional fields to
  `EventMsg::PatchApplyBegin` and `EventMsg::PatchApplyEnd`, but those
  were fairly lightweight.
  
  However, the `EventMsg`s emitted by core are the following:
  ```
  1) Auto-approved (no request for approval)

  - EventMsg::PatchApplyBegin
  - EventMsg::PatchApplyEnd
  
  2) Approved by user
  - EventMsg::ApplyPatchApprovalRequest
  - EventMsg::PatchApplyBegin
  - EventMsg::PatchApplyEnd
  
  3) Declined by user
  - EventMsg::ApplyPatchApprovalRequest
  - EventMsg::PatchApplyBegin
  - EventMsg::PatchApplyEnd
  ```
  
  For a request triggering an approval, this would result in:
  ```
  item/fileChange/requestApproval
  item/started
  item/completed
  ```
  
  which is different from the `ThreadItem::CommandExecution` flow
  introduced in https://github.com/openai/codex/pull/6758, which does the
  below and is preferable:
  ```
  item/started
  item/commandExecution/requestApproval
  item/completed
  ```
  
  To fix this, we leverage `TurnSummaryStore` on codex_message_processor
  to store a little bit of state, allowing us to fire `item/started` and
  `item/fileChange/requestApproval` whenever we receive the underlying
  `EventMsg::ApplyPatchApprovalRequest`, and no-oping when we receive the
  `EventMsg::PatchApplyBegin` later.
  
  This is much less invasive than modifying the order of EventMsg within
  core (I tried).
  
  The resulting payloads:
  ```

• [core] add optional status_code to error events (#6865)

  We want to better uncover error status code for clients. Add an optional

• fix: add more fields to ThreadStartResponse and ThreadResumeResponse (#6847)

  This adds the following fields to `ThreadStartResponse` and
  `ThreadResumeResponse`:
  
  ```rust
      pub model: String,
      pub model_provider: String,
      pub cwd: PathBuf,
      pub approval_policy: AskForApproval,
      pub sandbox: SandboxPolicy,
      pub reasoning_effort: Option<ReasoningEffort>,
  ```
  
  This is important because these fields are optional in
  `ThreadStartParams` and `ThreadResumeParams`, so the caller needs to be
  able to determine what values were ultimately used to start/resume the
  conversation. (Though note that any of these could be changed later
  between turns in the conversation.)
  
  Though to get this information reliably, it must be read from the
  internal `SessionConfiguredEvent` that is created in response to the
  start of a conversation. Because `SessionConfiguredEvent` (as defined in
  `codex-rs/protocol/src/protocol.rs`) did not have all of these fields, a
  number of them had to be added as part of this PR.
  
  Because `SessionConfiguredEvent` is referenced in many tests, test
  instances of `SessionConfiguredEvent` had to be updated, as well, which
  is why this PR touches so many files.

• [app-server] feat: add v2 command execution approval flow (#6758)

  This PR adds the API V2 version of the command‑execution approval flow
  for the shell tool.
  
  This PR wires the new RPC (`item/commandExecution/requestApproval`, V2
  only) and related events (`item/started`, `item/completed`, and
  `item/commandExecution/delta`, which are emitted in both V1 and V2)
  through the app-server
  protocol. The new approval RPC is only sent when the user initiates a
  turn with the new `turn/start` API so we don't break backwards
  compatibility with VSCE.
  
  The approach I took was to make as few changes to the Codex core as
  possible, leveraging existing `EventMsg` core events, and translating
  those in app-server. I did have to add additional fields to
  `EventMsg::ExecCommandEndEvent` to capture the command's input so that
  app-server can statelessly transform these events to a
  `ThreadItem::CommandExecution` item for the `item/completed` event.
  
  Once we stabilize the API and it's complete enough for our partners, we
  can work on migrating the core to be aware of command execution items as
  a first-class concept.
  
  **Note**: We'll need followup work to make sure these APIs work for the
  unified exec tool, but will wait til that's stable and landed before
  doing a pass on app-server.

• Handle "Don't Trust" directory selection in onboarding (#4941)

  Fixes #4940
  Fixes #4892
  
  When selecting "No, ask me to approve edits and commands" during
  onboarding, the code wasn't applying the correct approval policy,
  causing Codex to block all write operations instead of requesting
  approval.
  
  This PR fixes the issue by persisting the "DontTrust" decision in
  config.toml as `trust_level = "untrusted"` and handling it in the
  sandbox and approval policy logic, so Codex correctly asks for approval
  before making changes.

• [app-server] small fixes for JSON schema export and one-of types (#6614)

  A partner is consuming our generated JSON schema bundle for app-server
  and identified a few issues:
  - not all polymorphic / one-of types have a type descriminator
  - `"$ref": "#/definitions/v2/SandboxPolicy"` is missing
  - "Option<>" is an invalid schema name, and also unnecessary
  
  This PR:
  - adds the type descriminator to the various types that are missing it
  except for `SessionSource` and `SubAgentSource` because they are
  serialized to disk (adding this would break backwards compat for
  resume), and they should not be necessary to consume for an integration
  with app-server.
  - removes the special handling in `export.rs` of various types like
  SandboxPolicy, which turned out to be unnecessary and incorrect
  - filters out `Option<>` which was auto-generated for request params
  that don't need a body
  
  For context, we currently pull in wayyy more types than we need through
  the `EventMsg` god object which we are **not** planning to expose in API
  v2 (this is how I suspect `SessionSource` and `SubAgentSource` are being
  pulled in). But until we have all the necessary v2 notifications in
  place that will allow us to remove `EventMsg`, we will keep exporting it
  for now.

• [App-server] add new v2 events:item/reasoning/delta, item/agentMessage/delta & item/reasoning/summaryPartAdded (#6559)

  core event to app server event mapping:
  1. `codex/event/reasoning_content_delta` ->
  `item/reasoning/summaryTextDelta`.
  2. `codex/event/reasoning_raw_content_delta` ->
  `item/reasoning/textDelta`
  3. `codex/event/agent_message_content_delta` →
  `item/agentMessage/delta`.
  4. `codex/event/agent_reasoning_section_break` ->
  `item/reasoning/summaryPartAdded`.
  
  Also added a change in core to pass down content index, summary index
  and item id from events.
  
  Tested with the `git checkout owen/app_server_test_client && cargo run
  -p codex-app-server-test-client -- send-message-v2 "hello"` and verified
  that new events are emitted correctly.

• feat: shell_command tool (#6510)

  This adds support for a new variant of the shell tool behind a flag. To
  test, run `codex` with `--enable shell_command_tool`, which will
  register the tool with Codex under the name `shell_command` that accepts
  the following shape:
  
  ```python
  {
    command: str
    workdir: str | None,
    timeout_ms: int | None,
    with_escalated_permissions: bool | None,
    justification: str | None,
  }
  ```
  
  This is comparable to the existing tool registered under
  `shell`/`container.exec`. The primary difference is that it accepts
  `command` as a `str` instead of a `str[]`. The `shell_command` tool
  executes by running `execvp(["bash", "-lc", command])`, though the exact
  arguments to `execvp(3)` depend on the user's default shell.
  
  The hypothesis is that this will simplify things for the model. For
  example, on Windows, instead of generating:
  
  ```json
  {"command": ["pwsh.exe", "-NoLogo", "-Command", "ls -Name"]}
  ```
  
  The model could simply generate:
  
  ```json
  {"command": "ls -Name"}
  ```
  
  As part of this change, I extracted some logic out of `user_shell.rs` as
  `Shell::derive_exec_args()` so that it can be reused in
  `codex-rs/core/src/tools/handlers/shell.rs`. Note the original code
  generated exec arg lists like:
  
  ```javascript
  ["bash", "-lc", command]
  ["zsh", "-lc", command]
  ["pwsh.exe", "-NoProfile", "-Command", command]
  ```
  
  Using `-l` for Bash and Zsh, but then specifying `-NoProfile` for
  PowerShell seemed inconsistent to me, so I changed this in the new
  implementation while also adding a `use_login_shell: bool` option to
  make this explicit. If we decide to add a `login: bool` to
  `ShellCommandToolCallParams` like we have for unified exec:
  
  
  https://github.com/openai/codex/blob/807e2c27f0a9f2e85c50e7e6df5533f0d9b853c7/codex-rs/core/src/tools/handlers/unified_exec.rs#L33-L34
  
  Then this should make it straightforward to support.

• Include reasoning tokens in the context window calculation (#6161)

  This value is used to determine whether mid-turn compaction is required.
  Reasoning items are only excluded between turns (and soon will start to
  be preserved even across turns) so it's incorrect to subtract
  reasoning_output_tokens mid term.
  
  This will result in higher values reported between turns but we are also
  looking into preserving reasoning items for the entire conversation to
  improve performance and caching.
