  • Support original-detail metadata on MCP image outputs (#17714)
    ## Summary
    - honor `_meta["codex/imageDetail"] == "original"` on MCP image content
    and map it to `detail: "original"` where supported
    - strip that detail back out when the active model does not support
    original-detail image inputs
    - update code-mode `image(...)` to accept individual MCP image blocks
    - teach `js_repl` / `codex.emitImage(...)` to preserve the same hint
    from raw MCP image outputs
    - document the new `_meta` contract and add generic RMCP-backed coverage
    across protocol, core, code-mode, and js_repl paths
  • Add MCP tool wall time to model output (#17406)
    Include MCP wall time in the output so the model is aware of how long
    it's calls are taking.
  • chore: refactor name and namespace to single type (#17402)
    avoid passing them both around, unify on a type. this now also keys
    `ToolRegistry`.
    
    tests pass

  • Remove client_common tool re-exports (#16482)
    ## Why
    
    `codex-rs/core/src/client_common.rs` still had a `tools` re-export
    module that forwarded `codex_tools` types back into `codex-core`. After
    the earlier extraction work in #16379, #16471, #16477, and #16481, that
    extra layer no longer adds value.
    
    Removing it keeps dependencies explicit: the `codex-core` modules that
    actually use `ToolSpec` and related types now depend on `codex_tools`
    directly instead of reaching through `client_common`.
    
    ## What Changed
    
    - removed the `client_common::tools` re-export module from
    `core/src/client_common.rs`
    - updated the remaining `codex-core` consumers to import `codex_tools`
    directly
    - adjusted the affected test code to reference
    `codex_tools::ResponsesApiTool` directly as well
    
    This is a mechanical cleanup only. It does not change tool behavior or
    runtime logic.
    
    ## Testing
    
    - `cargo test -p codex-core client_common::tests`
    - `cargo test -p codex-core tools::router::tests`
    - `cargo test -p codex-core tools::context::tests`
    - `cargo test -p codex-core tools::spec::tests`
  • [hooks] add non-streaming (non-stdin style) shell-only PostToolUse support (#15531)
    CHAINED PR - note that base is eternal/hooks-pretooluse-bash, not main
    -- so the following PR should be first
    
    Matching post-tool hook to the pre-tool functionality here:
    https://github.com/openai/codex/pull/15211
    
    So, PreToolUse calls for plain shell calls, allows blocking. This
    PostToolUse call runs after the command executed
    
    example run:
    
    ```
    › as a test, run in parallel the following commands:
      - echo 'one'
      - echo '[block-pre-tool-use]'
      - echo '[block-post-tool-use]'
    
    
    ⚠ MCP startup incomplete (failed: notion, linear)

    • Ran them in parallel. Little wave report:

      - echo '[block-pre-tool-use]' was blocked before execution by the PreToolUse hook.
      - echo '[block-post-tool-use]' ran, but its result was blocked afterward by the PostToolUse hook.
    
      The hook messages were:
    
      - PreToolUse demo blocked the command. Remove [block-pre-tool-use] to continue.
      - PostToolUse demo blocked the result after execution. Remove [block-post-tool-use] to continue.
    
    
    › for the blocked messages (correctly blocked in this test) did the tool output land back into
      context?
    
    
    • Yeah, from this run:
    
      - PreToolUse block: the command itself did not execute, so no command output landed in context. Only
        the block message did.
      - PostToolUse block: the command did execute, but the actual stdout did not come back into context.
        Only the post-tool block message did.
    
      So the blocked notifications landed in context, but the blocked command payloads themselves did not.
      Nice clean guardrail, aloha.

  • Move string truncation helpers into codex-utils-string (#15572)
    - move the shared byte-based middle truncation logic from `core` into
    `codex-utils-string`

  • Add notify to code-mode (#14842)
    Allows model to send an out-of-band notification.
    
    The notification is injected as another tool call output for the same
    call_id.
  • Apply argument comment lint across codex-rs (#14652)
    ## Why
    
    Once the repo-local lint exists, `codex-rs` needs to follow the
    checked-in convention and CI needs to keep it from drifting. This commit
    applies the fallback `/*param*/` style consistently across existing
    positional literal call sites without changing those APIs.
    
    The longer-term preference is still to avoid APIs that require comments
    by choosing clearer parameter types and call shapes. This PR is
    intentionally the mechanical follow-through for the places where the
    existing signatures stay in place.
    
    After rebasing onto newer `main`, the rollout also had to cover newly
    introduced `tui_app_server` call sites. That made it clear the first cut
    of the CI job was too expensive for the common path: it was spending
    almost as much time installing `cargo-dylint` and re-testing the lint
    crate as a representative test job spends running product tests. The CI
    update keeps the full workspace enforcement but trims that extra
    overhead from ordinary `codex-rs` PRs.
    
    ## What changed
    
    - keep a dedicated `argument_comment_lint` job in `rust-ci`
    - mechanically annotate remaining opaque positional literals across
    `codex-rs` with exact `/*param*/` comments, including the rebased
    `tui_app_server` call sites that now fall under the lint
    - keep the checked-in style aligned with the lint policy by using
    `/*param*/` and leaving string and char literals uncommented
    - cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
    registry/git metadata in the lint job
    - split changed-path detection so the lint crate's own `cargo test` step
    runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
    - continue to run the repo wrapper over the `codex-rs` workspace, so
    product-code enforcement is unchanged
    
    Most of the code changes in this commit are intentionally mechanical
    comment rewrites or insertions driven by the lint itself.
    
    ## Verification
    
    - `./tools/argument-comment-lint/run.sh --workspace`
    - `cargo test -p codex-tui-app-server -p codex-tui`
    - parsed `.github/workflows/rust-ci.yml` locally with PyYAML

  • Add Smart Approvals guardian review across core, app-server, and TUI (#13860)
    ## Summary
    - add `approvals_reviewer = "user" | "guardian_subagent"` as the runtime
    control for who reviews approval requests
    - route Smart Approvals guardian review through core for command
    execution, file changes, managed-network approvals, MCP approvals, and
    delegated/subagent approval flows
    - expose guardian review in app-server with temporary unstable
    `item/autoApprovalReview/{started,completed}` notifications carrying
    `targetItemId`, `review`, and `action`
    - update the TUI so Smart Approvals can be enabled from `/experimental`,
    aligned with the matching `/approvals` mode, and surfaced clearly while
    reviews are pending or resolved
    
    ## Runtime model
    This PR does not introduce a new `approval_policy`.
    
    Instead:
    - `approval_policy` still controls when approval is needed
    - `approvals_reviewer` controls who reviewable approval requests are
    routed to:
      - `user`
      - `guardian_subagent`
    
    `guardian_subagent` is a carefully prompted reviewer subagent that
    gathers relevant context and applies a risk-based decision framework
    before approving or denying the request.
    
    The `smart_approvals` feature flag is a rollout/UI gate. Core runtime
    behavior keys off `approvals_reviewer`.
    
    When Smart Approvals is enabled from the TUI, it also switches the
    current `/approvals` settings to the matching Smart Approvals mode so
    users immediately see guardian review in the active thread:
    - `approval_policy = on-request`
    - `approvals_reviewer = guardian_subagent`
    - `sandbox_mode = workspace-write`
    
    Users can still change `/approvals` afterward.
    
    Config-load behavior stays intentionally narrow:
    - plain `smart_approvals = true` in `config.toml` remains just the
    rollout/UI gate and does not auto-set `approvals_reviewer`
    - the deprecated `guardian_approval = true` alias migration does
    backfill `approvals_reviewer = "guardian_subagent"` in the same scope
    when that reviewer is not already configured there, so old configs
    preserve their original guardian-enabled behavior
    
    ARC remains a separate safety check. For MCP tool approvals, ARC
    escalations now flow into the configured reviewer instead of always
    bypassing guardian and forcing manual review.
    
    ## Config stability
    The runtime reviewer override is stable, but the config-backed
    app-server protocol shape is still settling.
    
    - `thread/start`, `thread/resume`, and `turn/start` keep stable
    `approvalsReviewer` overrides
    - the config-backed `approvals_reviewer` exposure returned via
    `config/read` (including profile-level config) is now marked
    `[UNSTABLE]` / experimental in the app-server protocol until we are more
    confident in that config surface
    
    ## App-server surface
    This PR intentionally keeps the guardian app-server shape narrow and
    temporary.
    
    It adds generic unstable lifecycle notifications:
    - `item/autoApprovalReview/started`
    - `item/autoApprovalReview/completed`
    
    with payloads of the form:
    - `{ threadId, turnId, targetItemId, review, action? }`
    
    `review` is currently:
    - `{ status, riskScore?, riskLevel?, rationale? }`
    - where `status` is one of `inProgress`, `approved`, `denied`, or
    `aborted`
    
    `action` carries the guardian action summary payload from core when
    available. This lets clients render temporary standalone pending-review
    UI, including parallel reviews, even when the underlying tool item has
    not been emitted yet.
    
    These notifications are explicitly documented as `[UNSTABLE]` and
    expected to change soon.
    
    This PR does **not** persist guardian review state onto `thread/read`
    tool items. The intended follow-up is to attach guardian review state to
    the reviewed tool item lifecycle instead, which would improve
    consistency with manual approvals and allow thread history / reconnect
    flows to replay guardian review state directly.
    
    ## TUI behavior
    - `/experimental` exposes the rollout gate as `Smart Approvals`
    - enabling it in the TUI enables the feature and switches the current
    session to the matching Smart Approvals `/approvals` mode
    - disabling it in the TUI clears the persisted `approvals_reviewer`
    override when appropriate and returns the session to default manual
    review when the effective reviewer changes
    - `/approvals` still exposes the reviewer choice directly
    - the TUI renders:
    - pending guardian review state in the live status footer, including
    parallel review aggregation
      - resolved approval/denial state in history
    
    ## Scope notes
    This PR includes the supporting core/runtime work needed to make Smart
    Approvals usable end-to-end:
    - shell / unified-exec / apply_patch / managed-network / MCP guardian
    review
    - delegated/subagent approval routing into guardian review
    - guardian review risk metadata and action summaries for app-server/TUI
    - config/profile/TUI handling for `smart_approvals`, `guardian_approval`
    alias migration, and `approvals_reviewer`
    - a small internal cleanup of delegated approval forwarding to dedupe
    fallback paths and simplify guardian-vs-parent approval waiting (no
    intended behavior change)
    
    Out of scope for this PR:
    - redesigning the existing manual approval protocol shapes
    - persisting guardian review state onto app-server `ThreadItem`s
    - delegated MCP elicitation auto-review (the current delegated MCP
    guardian shim only covers the legacy `RequestUserInput` path)

  • Reuse tool runtime for code mode worker (#14496)
    ## Summary
    - create the turn-scoped `ToolCallRuntime` before starting the code mode
    worker so the worker reuses the same runtime and router
    - thread the shared runtime through the code mode service/worker path
    and use it for nested tool calls
    - model aborted tool calls as a concrete `ToolOutput` so aborted
    responses still produce valid tool output shapes
    
    ## Testing
    - `just fmt`
    - `cargo test -p codex-core` (still running locally)
  • fix: move inline codex-rs/core unit tests into sibling files (#14444)
    ## Why
    PR #13783 moved the `codex.rs` unit tests into `codex_tests.rs`. This
    applies the same extraction pattern across the rest of `codex-rs/core`
    so the production modules stay focused on runtime code instead of large
    inline test blocks.
    
    Keeping the tests in sibling files also makes follow-up edits easier to
    review because product changes no longer have to share a file with
    hundreds or thousands of lines of test scaffolding.
    
    ## What changed
    - replaced each inline `mod tests { ... }` in `codex-rs/core/src/**`
    with a path-based module declaration
    - moved each extracted unit test module into a sibling `*_tests.rs`
    file, using `mod_tests.rs` for `mod.rs` modules
    - preserved the existing `cfg(...)` guards and module-local structure so
    the refactor remains structural rather than behavioral
    
    ## Testing
    - `cargo test -p codex-core --lib` (`1653 passed; 0 failed; 5 ignored`)
    - `just fix -p codex-core`
    - `cargo fmt --check`
    - `cargo shear`
  • feat: search_tool migrate to bring you own tool of Responses API (#14274)
    ## Why
    
    to support a new bring your own search tool in Responses
    API(https://developers.openai.com/api/docs/guides/tools-tool-search#client-executed-tool-search)
    we migrating our bm25 search tool to use official way to execute search
    on client and communicate additional tools to the model.
    
    ## What
    - replace the legacy `search_tool_bm25` flow with client-executed
    `tool_search`
    - add protocol, SSE, history, and normalization support for
    `tool_search_call` and `tool_search_output`
    - return namespaced Codex Apps search results and wire namespaced
    follow-up tool calls back into MCP dispatch
  • Make unified exec session_id numeric (#14279)
    It's a number on the write_stdin input, make it a number on the output
    and also internally.
  • Add output schema to MCP tools and expose MCP tool results in code mode (#14236)
    Summary
    - drop `McpToolOutput` in favor of `CallToolResult`, moving its helpers
    to keep MCP tooling focused on the final result shape
    - wire the new schema definitions through code mode, context, handlers,
    and spec modules so MCP tools serialize the exact output shape expected
    by the model
    - extend code mode tests to cover multiple MCP call scenarios and ensure
    the serialized data matches the new schema
    - refresh JS runner helpers and protocol models alongside the schema
    changes
    
    Testing
    - Not run (not requested)
  • Reuse McpToolOutput in McpHandler (#14229)
    We already have a type to represent the MCP tool output, reuse it
    instead of the custom McpHandlerOutput
  • Expose strongly-typed result for exec_command (#14183)
    Summary
    - document output types for the various tool handlers and registry so
    the API exposes richer descriptions
    - update unified execution helpers and client tests to align with the
    new output metadata
    - clean up unused helpers across tool dispatch paths
    
    Testing
    - Not run (not requested)
  • Move exec command truncation into ExecCommandToolOutput (#14169)
    Summary
    - relocate truncation logic for exec command output into the new
    `ExecCommandToolOutput` response helper instead of centralized handler
    code
    - update all affected tools and unified exec handling to use the new
    response item structure and eliminate `Function(FunctionToolOutput)`
    responses
    - adjust context, registry, and handler interfaces to align with the new
    response semantics and error fields
    
    Testing
    - Not run (not requested)
  • Enforce single tool output type in codex handlers (#14157)
    We'll need to associate output schema with each tool. Each tool can only
    have on output type.
  • Add code_mode experimental feature (#13418)
    A much narrower and more isolated (no node features) version of js_repl
  • Refactor tool output into trait implementations (#14152)
    First state to making tool outputs strongly typed (and `renderable`).
  • Add under-development original-resolution view_image support (#13050)
    ## Summary
    
    Add original-resolution support for `view_image` behind the
    under-development `view_image_original_resolution` feature flag.
    
    When the flag is enabled and the target model is `gpt-5.3-codex` or
    newer, `view_image` now preserves original PNG/JPEG/WebP bytes and sends
    `detail: "original"` to the Responses API instead of using the legacy
    resize/compress path.
    
    ## What changed
    
    - Added `view_image_original_resolution` as an under-development feature
    flag.
    - Added `ImageDetail` to the protocol models and support for serializing
    `detail: "original"` on tool-returned images.
    - Added `PromptImageMode::Original` to `codex-utils-image`.
      - Preserves original PNG/JPEG/WebP bytes.
      - Keeps legacy behavior for the resize path.
    - Updated `view_image` to:
    - use the shared `local_image_content_items_with_label_number(...)`
    helper in both code paths
      - select original-resolution mode only when:
        - the feature flag is enabled, and
        - the model slug parses as `gpt-5.3-codex` or newer
    - Kept local user image attachments on the existing resize path; this
    change is specific to `view_image`.
    - Updated history/image accounting so only `detail: "original"` images
    use the docs-based GPT-5 image cost calculation; legacy images still use
    the old fixed estimate.
    - Added JS REPL guidance, gated on the same feature flag, to prefer JPEG
    at 85% quality unless lossless is required, while still allowing other
    formats when explicitly requested.
    - Updated tests and helper code that construct
    `FunctionCallOutputContentItem::InputImage` to carry the new `detail`
    field.
    
    ## Behavior
    
    ### Feature off
    - `view_image` keeps the existing resize/re-encode behavior.
    - History estimation keeps the existing fixed-cost heuristic.
    
    ### Feature on + `gpt-5.3-codex+`
    - `view_image` sends original-resolution images with `detail:
    "original"`.
    - PNG/JPEG/WebP source bytes are preserved when possible.
    - History estimation uses the GPT-5 docs-based image-cost calculation
    for those `detail: "original"` images.

  • Support multimodal custom tool outputs (#12948)
    ## Summary
    
    This changes `custom_tool_call_output` to use the same output payload
    shape as `function_call_output`, so freeform tools can return either
    plain text or structured content items.
    
    The main goal is to let `js_repl` return image content from nested
    `view_image` calls in its own `custom_tool_call_output`, instead of
    relying on a separate injected message.
    
    ## What changed
    
    - Changed `custom_tool_call_output.output` from `string` to
    `FunctionCallOutputPayload`
    - Updated freeform tool plumbing to preserve structured output bodies
    - Updated `js_repl` to aggregate nested tool content items and attach
    them to the outer `js_repl` result
    - Removed the old `js_repl` special case that injected `view_image`
    results as a separate pending user image message
    - Updated normalization/history/truncation paths to handle multimodal
    `custom_tool_call_output`
    - Regenerated app-server protocol schema artifacts
    
    ## Behavior
    
    Direct `view_image` calls still return a `function_call_output` with
    image content.
    
    When `view_image` is called inside `js_repl`, the outer `js_repl`
    `custom_tool_call_output` now carries:
    - an `input_text` item if the JS produced text output
    - one or more `input_image` items from nested tool results
    
    So the nested image result now stays inside the `js_repl` tool output
    instead of being injected as a separate message.
    
    ## Compatibility
    
    This is intended to be backward-compatible for resumed conversations.
    
    Older histories that stored `custom_tool_call_output.output` as a plain
    string still deserialize correctly, and older histories that used the
    previous injected-image-message flow also continue to resume.
    
    Added regression coverage for resuming a pre-change rollout containing:
    - string-valued `custom_tool_call_output`
    - legacy injected image message history

  • Fix js_repl view_image attachments in nested tool calls (#12725)
    ## Summary
    
    - Fix `js_repl` so `await codex.tool("view_image", { path })` actually
    attaches the image to the active turn when called from inside the JS
    REPL.
    - Restore the behavior expected by the existing `js_repl`
    image-attachment test.
    - This is a follow-up to
    [#12553](https://github.com/openai/codex/pull/12553), which changed
    `view_image` to return structured image content.
    
    ## Root Cause
    
    - [#12553](https://github.com/openai/codex/pull/12553) changed
    `view_image` from directly injecting a pending user image message to
    returning structured `function_call_output` content items.
    - The nested tool-call bridge inside `js_repl` serialized that tool
    response back to the JS runtime, but it did not mirror returned image
    content into the active turn.
    - As a result, `view_image` appeared to succeed inside `js_repl`, but no
    `input_image` was actually attached for the outer turn.
    
    ## What Changed
    
    - Updated the nested tool-call path in `js_repl` to inspect function
    tool responses for structured content items.
    - When a nested tool response includes `input_image` content, `js_repl`
    now injects a corresponding user `Message` into the active turn before
    returning the raw tool result back to the JS runtime.
    - Kept the normal JSON result flow intact, so `codex.tool(...)` still
    returns the original tool output object to JavaScript.
    
    ## Why
    
    - `js_repl` documentation and tests already assume that `view_image` can
    be used from inside the REPL to attach generated images to the model.
    - Without this fix, the nested call path silently dropped that
    attachment behavior.
  • Agent jobs (spawn_agents_on_csv) + progress UI (#10935)
    ## Summary
    - Add agent job support: spawn a batch of sub-agents from CSV, auto-run,
    auto-export, and store results in SQLite.
    - Simplify workflow: remove run/resume/get-status/export tools; spawn is
    deterministic and completes in one call.
    - Improve exec UX: stable, single-line progress bar with ETA; suppress
    sub-agent chatter in exec.
    
    ## Why
    Enables map-reduce style workflows over arbitrarily large repos using
    the existing Codex orchestrator. This addresses review feedback about
    overly complex job controls and non-deterministic monitoring.
    
    ## Demo (progress bar)
    ```
    ./codex-rs/target/debug/codex exec \
      --enable collab \
      --enable sqlite \
      --full-auto \
      --progress-cursor \
      -c agents.max_threads=16 \
      -C /Users/daveaitel/code/codex \
      - <<'PROMPT'
    Create /tmp/agent_job_progress_demo.csv with columns: path,area and 30 rows:
    path = item-01..item-30, area = test.
    
    Then call spawn_agents_on_csv with:
    - csv_path: /tmp/agent_job_progress_demo.csv
    - instruction: "Run `python - <<'PY'` to sleep a random 0.3–1.2s, then output JSON with keys: path, score (int). Set score = 1."
    - output_csv_path: /tmp/agent_job_progress_demo_out.csv
    PROMPT
    ```
    
    ## Review feedback addressed
    - Auto-start jobs on spawn; removed run/resume/status/export tools.
    - Auto-export on success.
    - More descriptive tool spec + clearer prompts.
    - Avoid deadlocks on spawn failure; pending/running handled safely.
    - Progress bar no longer scrolls; stable single-line redraw.
    
    ## Tests
    - `cd codex-rs && cargo test -p codex-exec`
    - `cd codex-rs && cargo build -p codex-cli`
  • feat(app-server, core): allow text + image content items for dynamic tool outputs (#10567)
    Took over the work that @aaronl-openai started here:
    https://github.com/openai/codex/pull/10397
    
    Now that app-server clients are able to set up custom tools (called
    `dynamic_tools` in app-server), we should expose a way for clients to
    pass in not just text, but also image outputs. This is something the
    Responses API already supports for function call outputs, where you can
    pass in either a string or an array of content outputs (text, image,
    file):
    https://platform.openai.com/docs/api-reference/responses/create#responses_create-input-input_item_list-item-function_tool_call_output-output-array-input_image
    
    So let's just plumb it through in Codex (with the caveat that we only
    support text and image for now). This is implemented end-to-end across
    app-server v2 protocol types and core tool handling.
    
    ## Breaking API change
    NOTE: This introduces a breaking change with dynamic tools, but I think
    it's ok since this concept was only recently introduced
    (https://github.com/openai/codex/pull/9539) and it's better to get the
    API contract correct. I don't think there are any real consumers of this
    yet (not even the Codex App).
    
    Old shape:
    `{ "output": "dynamic-ok", "success": true }`
    
    New shape:
    ```
    {
        "contentItems": [
          { "type": "inputText", "text": "dynamic-ok" },
          { "type": "inputImage", "imageUrl": "data:image/png;base64,AAA" }
        ]
      "success": true
    }
    ```
  • feat: replace custom mcp-types crate with equivalents from rmcp (#10349)
    We started working with MCP in Codex before
    https://crates.io/crates/rmcp was mature, so we had our own crate for
    MCP types that was generated from the MCP schema:
    
    
    https://github.com/openai/codex/blob/8b95d3e082376f4cb23e92641705a22afb28a9da/codex-rs/mcp-types/README.md
    
    Now that `rmcp` is more mature, it makes more sense to use their MCP
    types in Rust, as they handle details (like the `_meta` field) that our
    custom version ignored. Though one advantage that our custom types had
    is that our generated types implemented `JsonSchema` and `ts_rs::TS`,
    whereas the types in `rmcp` do not. As such, part of the work of this PR
    is leveraging the adapters between `rmcp` types and the serializable
    types that are API for us (app server and MCP) introduced in #10356.
    
    Note this PR results in a number of changes to
    `codex-rs/app-server-protocol/schema`, which merit special attention
    during review. We must ensure that these changes are still
    backwards-compatible, which is possible because we have:
    
    ```diff
    - export type CallToolResult = { content: Array<ContentBlock>, isError?: boolean, structuredContent?: JsonValue, };
    + export type CallToolResult = { content: Array<JsonValue>, structuredContent?: JsonValue, isError?: boolean, _meta?: JsonValue, };
    ```
    
    so `ContentBlock` has been replaced with the more general `JsonValue`.
    Note that `ContentBlock` was defined as:
    
    ```typescript
    export type ContentBlock = TextContent | ImageContent | AudioContent | ResourceLink | EmbeddedResource;
    ```
    
    so the deletion of those individual variants should not be a cause of
    great concern.
    
    Similarly, we have the following change in
    `codex-rs/app-server-protocol/schema/typescript/Tool.ts`:
    
    ```
    - export type Tool = { annotations?: ToolAnnotations, description?: string, inputSchema: ToolInputSchema, name: string, outputSchema?: ToolOutputSchema, title?: string, };
    + export type Tool = { name: string, title?: string, description?: string, inputSchema: JsonValue, outputSchema?: JsonValue, annotations?: JsonValue, icons?: Array<JsonValue>, _meta?: JsonValue, };
    ```
    
    so:
    
    - `annotations?: ToolAnnotations` ➡️ `JsonValue`
    - `inputSchema: ToolInputSchema` ➡️ `JsonValue`
    - `outputSchema?: ToolOutputSchema` ➡️ `JsonValue`
    
    and two new fields: `icons?: Array<JsonValue>, _meta?: JsonValue`

  • feat: better UI for unified_exec (#6515)
    <img width="376" height="132" alt="Screenshot 2025-11-12 at 17 36 22"
    src="https://github.com/user-attachments/assets/ce693f0d-5ca0-462e-b170-c20811dcc8d5"

  • feature: Add "!cmd" user shell execution (#2471)
    feature: Add "!cmd" user shell execution
    
    This change lets users run local shell commands directly from the TUI by
    prefixing their input with ! (e.g. !ls). Output is truncated to keep the
    exec cell usable, and Ctrl-C cleanly
      interrupts long-running commands (e.g. !sleep 10000).
    
    **Summary of changes**
    
    - Route Op::RunUserShellCommand through a dedicated UserShellCommandTask
    (core/src/tasks/user_shell.rs), keeping the task logic out of codex.rs.
    - Reuse the existing tool router: the task constructs a ToolCall for the
    local_shell tool and relies on ShellHandler, so no manual MCP tool
    lookup is required.
    - Emit exec lifecycle events (ExecCommandBegin/ExecCommandEnd) so the
    TUI can show command metadata, live output, and exit status.
    
    **End-to-end flow**
    
      **TUI handling**
    
    1. ChatWidget::submit_user_message (TUI) intercepts messages starting
    with !.
    2. Non-empty commands dispatch Op::RunUserShellCommand { command };
    empty commands surface a help hint.
    3. No UserInput items are created, so nothing is enqueued for the model.
    
      **Core submission loop**
    4. The submission loop routes the op to handlers::run_user_shell_command
    (core/src/codex.rs).
    5. A fresh TurnContext is created and Session::spawn_user_shell_command
    enqueues UserShellCommandTask.
    
      **Task execution**
    6. UserShellCommandTask::run emits TaskStartedEvent, formats the
    command, and prepares a ToolCall targeting local_shell.
      7. ToolCallRuntime::handle_tool_call dispatches to ShellHandler.
    
      **Shell tool runtime**
    8. ShellHandler::run_exec_like launches the process via the unified exec
    runtime, honoring sandbox and shell policies, and emits
    ExecCommandBegin/End.
    9. Stdout/stderr are captured for the UI, but the task does not turn the
    resulting ToolOutput into a model response.
    
      **Completion**
    10. After ExecCommandEnd, the task finishes without an assistant
    message; the session marks it complete and the exec cell displays the
    final output.
    
      **Conversation context**
    
    - The command and its output never enter the conversation history or the
    model prompt; the flow is local-only.
      - Only exec/task events are emitted for UI rendering.

  • [MCP] Render MCP tool call result images to the model (#5600)
    It's pretty amazing we have gotten here without the ability for the
    model to see image content from MCP tool calls.
    
    This PR builds off of 4391 and fixes #4819. I would like @KKcorps to get
    adequete credit here but I also want to get this fix in ASAP so I gave
    him a week to update it and haven't gotten a response so I'm going to
    take it across the finish line.
    
    
    This test highlights how absured the current situation is. I asked the
    model to read this image using the Chrome MCP
    <img width="2378" height="674" alt="image"
    src="https://github.com/user-attachments/assets/9ef52608-72a2-4423-9f5e-7ae36b2b56e0"
    />
    
    After this change, it correctly outputs:
    > Captured the page: image dhows a dark terminal-style UI labeled
    `OpenAI Codex (v0.0.0)` with prompt `model: gpt-5-codex medium` and
    working directory `/codex/codex-rs`
    (and more)  
    
    Before this change, it said:
    > Took the full-page screenshot you asked for. It shows a long,
    horizontally repeating pattern of stylized people in orange, light-blue,
    and mustard clothing, holding hands in alternating poses against a white
    background. No text or other graphics-just rows of flat illustration
    stretching off to the right.
    
    Without this change, the Figma, Playwright, Chrome, and other visual MCP
    servers are pretty much entirely useless.
    
    I tested this change with the openai respones api as well as a third
    party completions api
  • Pass TurnContext around instead of sub_id (#5421)
    Today `sub_id` is an ID of a single incoming Codex Op submition. We then
    associate all events triggered by this operation using the same
    `sub_id`.
    
    At the same time we are also creating a TurnContext per submission and
    we'd like to start associating some events (item added/item completed)
    with an entire turn instead of just the operation that started it.
    
    Using turn context when sending events give us flexibility to change
    notification scheme.
  • chore: rework tools execution workflow (#5278)
    Re-work the tool execution flow. Read `orchestrator.rs` to understand
    the structure
  • feat: parallel tool calls (#4663)
    Add parallel tool calls. This is configurable at model level and tool
    level
  • chore: refactor tool handling (#4510)
    # Tool System Refactor
    
    - Centralizes tool definitions and execution in `core/src/tools/*`:
    specs (`spec.rs`), handlers (`handlers/*`), router (`router.rs`),
    registry/dispatch (`registry.rs`), and shared context (`context.rs`).
    One registry now builds the model-visible tool list and binds handlers.
    - Router converts model responses to tool calls; Registry dispatches
    with consistent telemetry via `codex-rs/otel` and unified error
    handling. Function, Local Shell, MCP, and experimental `unified_exec`
    all flow through this path; legacy shell aliases still work.
    - Rationale: reduce per‑tool boilerplate, keep spec/handler in sync, and
    make adding tools predictable and testable.
    
    Example: `read_file`
    - Spec: `core/src/tools/spec.rs` (see `create_read_file_tool`,
    registered by `build_specs`).
    - Handler: `core/src/tools/handlers/read_file.rs` (absolute `file_path`,
    1‑indexed `offset`, `limit`, `L#: ` prefixes, safe truncation).
    - E2E test: `core/tests/suite/read_file.rs` validates the tool returns
    the requested lines.
    
    ## Next steps:
    - Decompose `handle_container_exec_with_params` 
    - Add parallel tool calls
