  • feat: add support for /diff command (#1389)
    Adds support for a `/diff` command comparable to the one available in
    the TypeScript CLI.

    While here, changed the `SlashCommand` enum so the declared variant
    order is the order the commands appear in the popup menu. This way,
    `/toggle-mouse-mode` is listed last, as it is the least likely to be
    used.
    
    Fixes https://github.com/openai/codex/issues/1253.
  • [Rust] Allow resuming a session that was killed with ctrl + c (#1387)
    Previously, if you ctrl+c'd a conversation, all subsequent turns would
    400 because the Responses API never got a response for one of its call
    ids. This ensures that if we aren't sending a call id by hand, we
    generate a synthetic aborted call.
    
    Fixes #1244

  • feat: show number of tokens remaining in UI (#1388)
    When using the OpenAI Responses API, we now record the `usage` field for
    a `"response.completed"` event, which includes metrics about the number
    of tokens consumed. We also introduce `openai_model_info.rs`, which
    includes current data about the most common OpenAI models available via
    the API (specifically `context_window` and `max_output_tokens`). If
    Codex does not recognize the model, you can set `model_context_window`
    and `model_max_output_tokens` explicitly in `config.toml`.
    
    When then introduce a new event type to `protocol.rs`, `TokenCount`,
    which includes the `TokenUsage` for the most recent turn.
    
    Finally, we update the TUI to record the running sum of tokens used so
    the percentage of available context window remaining can be reported via
    the placeholder text for the composer:

    We could certainly get much fancier with this (such as reporting the
    estimated cost of the conversation), but for now, we are just trying to
    achieve feature parity with the TypeScript CLI.
    
    Though arguably this improves upon the TypeScript CLI, as the TypeScript
    CLI uses heuristics to estimate the number of tokens used rather than
    using the `usage` information directly:

  • feat: standalone file search CLI (#1386)
    Standalone fuzzy filename search library that should be helpful in
    addressing https://github.com/openai/codex/issues/1261.
  • feat: add --dangerously-bypass-approvals-and-sandbox (#1384)
    This PR reworks `assess_command_safety()` so that the combination of
    `AskForApproval::Never` and `SandboxPolicy::DangerFullAccess` ensures
    that commands are run without _any_ sandbox and the user should never be
    prompted. In turn, it adds support for a new
    `--dangerously-bypass-approvals-and-sandbox` flag (that cannot be used
    with `--approval-policy` or `--full-auto`) that sets both of those
    options.
    
    Fixes https://github.com/openai/codex/issues/1254
  • chore: rename AskForApproval::UnlessAllowListed to AskForApproval::UnlessTrusted (#1385)
    We could just rename to `Untrusted` instead of `UnlessTrusted`, but I
    think `AskForApproval::UnlessTrusted` reads a bit better.
  • chore: improve docstring for --full-auto (#1379)
    Reference `-c sandbox.mode=workspace-write` in the docstring and users
    can read the config docs for `sandbox` for more information.
  • chore: rename unless-allow-listed to untrusted (#1378)
    For the `approval_policy` config option, renames `unless-allow-listed`
    to `untrusted`. In general, when it comes to exec'ing commands, I think
    "trusted" is a more accurate term than "safe."
    
    Also drops the `AskForApproval::AutoEdit` variant, as we were not really
    making use of it, anyway.
    
    Fixes https://github.com/openai/codex/issues/1250.

  • chore: install just in the devcontainer for Linux development (#1375)
    Apparently `just` was added to `apt` in Ubuntu 24, so this required
    updating the Ubuntu version in the `Dockerfile` to make it so we could
    simply `apt install just`.
    
    Though then that caused a conflict with the custom `dev` user we were
    using, though the end result seems simpler since now we just use the
    default `ubuntu` user provided by Ubuntu 24.
  • chore: install clippy and rustfmt in the devcontainer for Linux development (#1374)
    I discovered it was difficult to do development in the devcontainer
    without these tools available.
  • feat: redesign sandbox config (#1373)
    This is a major redesign of how sandbox configuration works and aims to
    fix https://github.com/openai/codex/issues/1248. Specifically, it
    replaces `sandbox_permissions` in `config.toml` (and the
    `-s`/`--sandbox-permission` CLI flags) with a "table" with effectively
    three variants:
    
    ```toml
    # Safest option: full disk is read-only, but writes and network access are disallowed.
    [sandbox]
    mode = "read-only"
    
    # The cwd of the Codex task is writable, as well as $TMPDIR on macOS.
    # writable_roots can be used to specify additional writable folders.
    [sandbox]
    mode = "workspace-write"
    writable_roots = []  # Optional, defaults to the empty list.
    network_access = false  # Optional, defaults to false.
    
    # Disable sandboxing: use at your own risk!!!
    [sandbox]
    mode = "danger-full-access"
    ```
    
    This should make sandboxing easier to reason about. While we have
    dropped support for `-s`, the way it works now is:
    
    - no flags => `read-only`
    - `--full-auto` => `workspace-write`
    - currently, there is no way to specify `danger-full-access` via a CLI
    flag, but we will revisit that as part of
    https://github.com/openai/codex/issues/1254
    
    Outstanding issue:
    
    - As noted in the `TODO` on `SandboxPolicy::is_unrestricted()`, we are
    still conflating sandbox preferences with approval preferences in that
    case, which needs to be cleaned up.
  • add: responses api support for azure (#1321)
    - Use Responses API for Azure provider endpoints
    - Added a unit test to catch regression on the change from
    `/chat/completions` to `/responses`
    - Updated the default AOAI api version from `2025-03-01-preview` to
    `2025-04-01-preview` to avoid user/400 errors due to missing summary
    support in the March API version.
    - Changes have been tested locally on AOAI endpoints
  • feat(ts): provider‑specific API‑key discovery and clearer Azure guidance (#1324)
    ## Summary
    
    This PR refactors the Codex CLI authentication flow so that
    **non-OpenAI** providers (for example **azure**, or any future addition)
    can supply their API key through a dedicated environment variable
    without triggering the OpenAI login flow.
    
    Key behaviours introduced:
    
    * When `provider !== "openai"` the CLI consults `src/utils/providers.ts`
    to locate the correct environment variable (`AZURE_OPENAI_API_KEY`,
    `GEMINI_API_KEY`, and so on) before considering any interactive login.
    * Credit redemption (`--free`) and PKCE login now run **only** when the
    provider is OpenAI, eliminating unwanted browser prompts for Azure and
    others.
    * User-facing error messages are revamped to guide Azure users to
    **[https://ai.azure.com/](https://ai.azure.com)** and show the exact
    variable name they must set.
    * All code paths still export `OPENAI_API_KEY` so legacy scripts
    continue to operate unchanged.
    
    ---
    
    ## Example `config.json`
    
    ```jsonc
    {
      "model": "codex-mini",
      "provider": "azure",
      "providers": {
        "azure": {
          "name": "AzureOpenAI",
          "baseURL": "https://ai-<project-name>.openai.azure.com/openai",
          "envKey": "AZURE_OPENAI_API_KEY"
        }
      },
      "history": {
        "maxSize": 1000,
        "saveHistory": true,
        "sensitivePatterns": []
      }
    }
    ```
    
    With this file in `~/.codex/config.json`, a single command line is
    enough:
    
    ```bash
    export AZURE_OPENAI_API_KEY="<your-key>"
    codex "Hello from Azure"
    ```
    
    No browser window opens, and the CLI works in entirely non-interactive
    mode.
    
    ---
    
    ## Rationale
    
    The new flow enables Codex to run **asynchronously** in sandboxed
    environments such as GitHub Actions pipelines. By passing `--provider
    azure` (or setting it in `config.json`) and exporting the correct key,
    CI/CD jobs can invoke Codex without any ChatGPT-style login or PKCE
    round-trip. This unlocks fully automated testing and deployment
    scenarios.

    ## What’s changed
    
    | File | Type | Description |
    | ------------------------ | ------------------- |
    -----------------------------------------------------------------------------------------------------------------------------
    |
    | `codex-cli/src/cli.tsx` | **feat / refactor** | +43 / -20 lines.
    Imports `providers`, adds early provider-specific key lookup, gates
    `--free` redemption, rewrites help text. |
    | `src/utils/providers.ts` | **chore** | Now consumed by CLI for env-var
    discovery. |
    
    ---
    
    ## How to test
    
    ```bash
    # Azure example
    export AZURE_OPENAI_API_KEY="<your-key>"
    codex --provider azure "Automated run in CI"
    
    # OpenAI example (unchanged behaviour)
    codex --provider openai --login "Standard OpenAI flow"
    ```
    
    Expected outcomes:
    
    * Azure and other provider paths are non-interactive when provider flag
    is passed.
    * The CLI always sets `OPENAI_API_KEY` for backward compatibility.
    
    ---
    
    ## Checklist
    
    * [x] Logic behind provider-specific env-var lookup added.
    * [x] Redundant OpenAI login steps removed for other providers.
    * [x] Unit tests cover new branches.
    * [x] README and sample config updated.
    * [x] CI passes on all supported Node versions.

  • docs: update codex-rs/README.md to list new features in the Rust CLI (#1267)

  • codex-rs: Rename /clear to /new, make it start an entirely new chat (#1264)
    I noticed that `/clear` wasn't fully clearing chat history; it would
    clear the chat history widgets _in the UI_, but the LLM still had access
    to information from previous messages.
    
    This PR renames `/clear` to `/new` for clarity as per Michael's
    suggestion, resetting `app_state` to a fresh `ChatWidget`.
  • chore: ensure next Node.js release includes musl binaries for arm64 Linux (#1232)
    Target a workflow with more recent binary artifacts.
  • fix: use aarch64-unknown-linux-musl instead of aarch64-unknown-linux-gnu (#1228)
    Now that we have published a GitHub Release that contains arm64 musl
    artifacts for Linux, update the following scripts to take advantage of
    them:
    
    - `dotslash-config.json` now uses musl artifacts for the `linux-aarch64`
    target
    - `install_native_deps.sh` for the TypeScript CLI now includes
    `codex-linux-sandbox-aarch64-unknown-linux-musl` instead of
    `codex-linux-sandbox-aarch64-unknown-linux-gnu` for sandboxing
    - `codex-cli/bin/codex.js` now checks for `aarch64-unknown-linux-musl`
    artifacts instead of `aarch64-unknown-linux-gnu` ones
  • fix: include codex-linux-sandbox-aarch64-unknown-linux-musl in the set of release artifacts (#1230)
    This was missed in https://github.com/openai/codex/pull/1225. Once we
    create a new GitHub Release with this change, we can use the URL from
    the workflow that triggered the release in
    https://github.com/openai/codex/pull/1228.
  • fix: support arm64 build for Linux (#1225)
    Users were running into issues with glibc mismatches on arm64 linux. In
    the past, we did not provide a musl build for arm64 Linux because we had
    trouble getting the openssl dependency to build correctly. Though today
    I just tried the same trick in `Cargo.toml` that we were doing for
    `x86_64-unknown-linux-musl` (using `openssl-sys` with `features =
    ["vendored"]`), so I'm not sure what problem we had in the past the
    builds "just worked" today!
    
    Though one tweak that did have to be made is that the integration tests
    for Seccomp/Landlock empirically require longer timeouts on arm64 linux,
    or at least on the `ubuntu-24.04-arm` GitHub Runner. As such, we change
    the timeouts for arm64 in `codex-rs/linux-sandbox/tests/landlock.rs`.
    
    Though in solving this problem, I decided I needed a turnkey solution
    for testing the Linux build(s) from my Mac laptop, so this PR introduces
    `.devcontainer/Dockerfile` and `.devcontainer/devcontainer.json` to
    facilitate this. Detailed instructions are in `.devcontainer/README.md`.
    
    We will update `dotslash-config.json` and other release-related scripts
    in a follow-up PR.
  • feat: add support for login with ChatGPT (#1212)
    This does not implement the full Login with ChatGPT experience, but it
    should unblock people.
    
    **What works**
    
    * The `codex` multitool now has a `login` subcommand, so you can run
    `codex login`, which should write `CODEX_HOME/auth.json` if you complete
    the flow successfully. The TUI will now read the `OPENAI_API_KEY` from
    `auth.json`.
    * The TUI should refresh the token if it has expired and the necessary
    information is in `auth.json`.
    * There is a `LoginScreen` in the TUI that tells you to run `codex
    login` if both (1) your model provider expects to use `OPENAI_API_KEY`
    as its env var, and (2) `OPENAI_API_KEY` is not set.
    
    **What does not work**
    
    * The `LoginScreen` does not support the login flow from within the TUI.
    Instead, it tells you to quit, run `codex login`, and then run `codex`
    again.
    * `codex exec` does read from `auth.json` yet, nor does it direct the
    user to go through the login flow if `OPENAI_API_KEY` is not be found.
    * The `maybeRedeemCredits()` function from `get-api-key.tsx` has not
    been ported from TypeScript to `login_with_chatgpt.py` yet:
    
    
    https://github.com/openai/codex/blob/a67a67f3258fc21e147b6786a143fe3e15e6d5ba/codex-cli/src/utils/get-api-key.tsx#L84-L89
    
    **Implementation**
    
    Currently, the OAuth flow requires running a local webserver on
    `127.0.0.1:1455`. It seemed wasteful to incur the additional binary cost
    of a webserver dependency in the Rust CLI just to support login, so
    instead we implement this logic in Python, as Python has a `http.server`
    module as part of its standard library. Specifically, we bundle the
    contents of a single Python file as a string in the Rust CLI and then
    use it to spawn a subprocess as `python3 -c
    {{SOURCE_FOR_PYTHON_SERVER}}`.
    
    As such, the most significant files in this PR are:
    
    ```
    codex-rs/login/src/login_with_chatgpt.py
    codex-rs/login/src/lib.rs
    ```
    
    Now that the CLI may load `OPENAI_API_KEY` from the environment _or_
    `CODEX_HOME/auth.json`, we need a new abstraction for reading/writing
    this variable, so we introduce:
    
    ```
    codex-rs/core/src/openai_api_key.rs
    ```
    
    Note that `std::env::set_var()` is [rightfully] `unsafe` in Rust 2024,
    so we use a LazyLock<RwLock<Option<String>>> to store `OPENAI_API_KEY`
    so it is read in a thread-safe manner.
    
    Ultimately, it should be possible to go through the entire login flow
    from the TUI. This PR introduces a placeholder `LoginScreen` UI for that
    right now, though the new `codex login` subcommand introduced in this PR
    should be a viable workaround until the UI is ready.
    
    **Testing**
    
    Because the login flow is currently implemented in a standalone Python
    file, you can test it without building any Rust code as follows:
    
    ```
    rm -rf /tmp/codex_home && mkdir /tmp/codex_home
    CODEX_HOME=/tmp/codex_home python3 codex-rs/login/src/login_with_chatgpt.py
    ```
    
    For reference:
    
    * the original TypeScript implementation was introduced in
    https://github.com/openai/codex/pull/963
    * support for redeeming credits was later added in
    https://github.com/openai/codex/pull/974
  • codex-rs: make tool calls prettier (#1211)
    This PR overhauls how active tool calls and completed tool calls are
    displayed:
    
    1. More use of colour to indicate success/failure and distinguish
    between components like tool name+arguments
    2. Previously, the entire `CallToolResult` was serialized to JSON and
    pretty-printed. Now, we extract each individual `CallToolResultContent`
    and print those
    1. The previous solution was wasting space by unnecessarily showing
    details of the `CallToolResult` struct to users, without formatting the
    actual tool call results nicely
    2. We're now able to show users more information from tool results in
    less space, with nicer formatting when tools return JSON results
    
    ### Before:

    />
    
    ## Future Work
    
    1. Integrate image tool result handling better. We should be able to
    display images even if they're not the first `CallToolResultContent`
    2. Users should have some way to view the full version of truncated tool
    results
    3. It would be nice to add some left padding for tool results, make it
    more clear that they are results. This is doable, just a little fiddly
    due to the way `first_visible_line` scrolling works
    4. There's almost certainly a better way to format JSON than "all on 1
    line with spaces to make Ratatui wrapping work". But I think that works
    OK for now.
  • fix: always send full instructions when using the Responses API (#1207)
    This fixes a longstanding error in the Rust CLI where `codex.rs`
    contained an errant `is_first_turn` check that would exclude the user
    instructions for subsequent "turns" of a conversation when using the
    responses API (i.e., when `previous_response_id` existed).
    
    While here, renames `Prompt.instructions` to `Prompt.user_instructions`
    since we now have quite a few levels of instructions floating around.
    Also removed an unnecessary use of `clone()` in
    `Prompt.get_full_instructions()`.
  • fix: provide tolerance for apply_patch tool (#993)
    As explained in detail in the doc comment for `ParseMode::Lenient`, we
    have observed that GPT-4.1 does not always generate a valid invocation
    of `apply_patch`. Fortunately, the error is predictable, so we introduce
    some new logic to the `codex-apply-patch` crate to recover from this
    error.
    
    Because we would like to avoid this becoming a de facto standard (as it
    would be incompatible if `apply_patch` were provided as an actual
    executable, unless we also introduced the lenient behavior in the
    executable, as well), we require passing `ParseMode::Lenient` to
    `parse_patch_text()` to make it clear that the caller is opting into
    supporting this special case.
    
    Note the analogous change to the TypeScript CLI was
    https://github.com/openai/codex/pull/930. In addition to changing the
    accepted input to `apply_patch`, it also introduced additional
    instructions for the model, which we include in this PR.
    
    Note that `apply-patch` does not depend on either `regex` or
    `regex-lite`, so some of the checks are slightly more verbose to avoid
    introducing this dependency.
    
    That said, this PR does not leverage the existing
    `extract_heredoc_body_from_apply_patch_command()`, which depends on
    `tree-sitter` and `tree-sitter-bash`:
    
    
    https://github.com/openai/codex/blob/5a5aa899143f9b9ef606692c401b010368b15bdb/codex-rs/apply-patch/src/lib.rs#L191-L246
    
    though perhaps it should.
  • chore: replace regex with regex-lite, where appropriate (#1200)
    As explained on https://crates.io/crates/regex-lite, `regex-lite` is a
    lighter alternative to `regex` and seems to be sufficient for our
    purposes.
  • feat: make reasoning effort/summaries configurable (#1199)
    Previous to this PR, we always set `reasoning` when making a request
    using the Responses API:
    
    
    https://github.com/openai/codex/blob/d7245cbbc9d8ff5446da45e5951761103492476d/codex-rs/core/src/client.rs#L108-L111
    
    Though if you tried to use the Rust CLI with `--model gpt-4.1`, this
    would fail with:
    
    ```shell
    "Unsupported parameter: 'reasoning.effort' is not supported with this model."
    ```
    
    We take a cue from the TypeScript CLI, which does a check on the model
    name:
    
    
    https://github.com/openai/codex/blob/d7245cbbc9d8ff5446da45e5951761103492476d/codex-cli/src/utils/agent/agent-loop.ts#L786-L789
    
    This PR does a similar check, though also adds support for the following
    config options:
    
    ```
    model_reasoning_effort = "low" | "medium" | "high" | "none"
    model_reasoning_summary = "auto" | "concise" | "detailed" | "none"
    ```
    
    This way, if you have a model whose name happens to start with `"o"` (or
    `"codex"`?), you can set these to `"none"` to explicitly disable
    reasoning, if necessary. (That said, it seems unlikely anyone would use
    the Responses API with non-OpenAI models, but we provide an escape
    hatch, anyway.)
    
    This PR also updates both the TUI and `codex exec` to show `reasoning
    effort` and `reasoning summaries` in the header.
  • fix: chat completions API now also passes tools along (#1167)
    Prior to this PR, there were two big misses in `chat_completions.rs`:
    
    1. The loop in `stream_chat_completions()` was only including items of
    type `ResponseItem::Message` when building up the `"messages"` JSON for
    the `POST` request to the `chat/completions` endpoint. This fixes things
    by ensuring other variants (`FunctionCall`, `LocalShellCall`, and
    `FunctionCallOutput`) are included, as well.
    2. In `process_chat_sse()`, we were not recording tool calls and were
    only emitting items of type
    `ResponseEvent::OutputItemDone(ResponseItem::Message)` to the stream.
    Now we introduce `FunctionCallState`, which is used to accumulate the
    `delta`s of type `tool_calls`, so we can ultimately emit a
    `ResponseItem::FunctionCall`, when appropriate.
    
    While function calling now appears to work for chat completions with my
    local testing, I believe that there are still edge cases that are not
    covered and that this codepath would benefit from a battery of
    integration tests. (As part of that further cleanup, we should also work
    to support streaming responses in the UI.)
    
    The other important part of this PR is some cleanup in
    `core/src/codex.rs`. In particular, it was hard to reason about how
    `run_task()` was building up the list of messages to include in a
    request across the various cases:
    
    - Responses API
    - Chat Completions API
    - Responses API used in concert with ZDR
    
    I like to think things are a bit cleaner now where:
    
    - `zdr_transcript` (if present) contains all messages in the history of
    the conversation, which includes function call outputs that have not
    been sent back to the model yet
    - `pending_input` includes any messages the user has submitted while the
    turn is in flight that need to be injected as part of the next `POST` to
    the model
    - `input_for_next_turn` includes the tool call outputs that have not
    been sent back to the model yet
  • chore: logging cleanup (#1196)
    Update what we log to make `RUST_LOG=debug` a bit easier to work with.

  • feat: show the version when starting Codex (#1182)
    The TypeScript version of the CLI shows the version when it starts up,
    which is helpful when users share screenshots (and nice to know, as a
    user).
  • feat: add hide_agent_reasoning config option (#1181)
    This PR introduces a `hide_agent_reasoning` config option (that defaults
    to `false`) that users can enable to make the output less verbose by
    suppressing reasoning output.
    
    To test, verified that this includes agent reasoning in the output:
    
    ```
    echo hello | just exec
    ```
    
    whereas this does not:
    
    ```
    echo hello | just exec --config hide_agent_reasoning=false
    ```
  • feat: dim the timestamp in the exec output (#1180)
    This required changing `ts_println!()` to take `$self:ident`, which is a
    bit more verbose, but the usability improvement seems worth it.
    
    Also eliminated an unnecessary `.to_string()` while here.
  • feat: grab-bag of improvements to exec output (#1179)
    Fixes:
    
    * Instantiate `EventProcessor` earlier in `lib.rs` so
    `print_config_summary()` can be an instance method of it and leverage
    its various `Style` fields to ensure it honors `with_ansi` properly.
    * After printing the config summary, print out user's prompt with the
    heading `User instructions:`. As noted in the comment, now that we can
    read the instructions via stdin as of #1178, it is helpful to the user
    to ensure they know what instructions were given to Codex.
    * Use same colors/bold/italic settings for headers as the TUI, making
    the output a bit easier to read.
  • feat: for codex exec, if PROMPT is not specified, read from stdin if not a TTY (#1178)
    This attempts to make `codex exec` more flexible in how the prompt can
    be passed:
    
    * as before, it can be passed as a single string argument
    * if `-` is passed as the value, the prompt is read from stdin
    * if no argument is passed _and stdin is a tty_, prints a warning to
    stderr that no prompt was specified an exits non-zero.
    * if no argument is passed _and stdin is NOT a tty_, prints `Reading
    prompt from stdin...` to stderr to let the user know that Codex will
    wait until it reads EOF from stdin to proceed. (You can repro this case
    by doing `yes | just exec` since stdin is not a TTY in that case but it
    also never reaches EOF).
  • fix: introduce create_tools_json() and share it with chat_completions.rs (#1177)
    The main motivator behind this PR is that `stream_chat_completions()`
    was not adding the `"tools"` entry to the payload posted to the
    `/chat/completions` endpoint. This (1) refactors the existing logic to
    build up the `"tools"` JSON from `client.rs` into `openai_tools.rs`, and
    (2) updates the use of responses API (`client.rs`) and chat completions
    API (`chat_completions.rs`) to both use it.
    
    Note this PR alone is not sufficient to get tool calling from chat
    completions working: that is done in
    https://github.com/openai/codex/pull/1167.

  • fix: add extra debugging to GitHub Action (#1173)
    https://github.com/openai/codex/actions/runs/15352839832/job/43205041563
    appeared to fail around `postComment()`, but I don't see the output from
    `fail()` in the logs. Adding a bit more info.
  • fix: update outdated repo setup in codex.yml (#1171)
    We should do some work to share the setup logic across `codex.yml`,
    `ci.yml`, and `rust-ci.yml`.
  • feat: initial import of experimental GitHub Action (#1170)
    This is a first cut at a GitHub Action that lets you define prompt
    templates in `.md` files under `.github/codex/labels` that will run
    Codex with the associated prompt when the label is added to a GitHub
    pull request.
    
    For example, this PR includes these files:
    
    ```
    .github/codex/labels/codex-attempt.md
    .github/codex/labels/codex-code-review.md
    .github/codex/labels/codex-investigate-issue.md
    ```
    
    And the new `.github/workflows/codex.yml` workflow declares the
    following triggers:
    
    ```yaml
    on:
      issues:
        types: [opened, labeled]
      pull_request:
        branches: [main]
        types: [labeled]
    ```
    
    as well as the following expression to gate the action:
    
    ```
    jobs:
      codex:
        if: |
          (github.event_name == 'issues' && (
            (github.event.action == 'labeled' && (github.event.label.name == 'codex-attempt' || github.event.label.name == 'codex-investigate-issue'))
          )) ||
          (github.event_name == 'pull_request' && github.event.action == 'labeled' && github.event.label.name == 'codex-code-review')
    ```
    
    Note the "actor" who added the label must have write access to the repo
    for the action to take effect.
    
    After adding a label, the action will "ack" the request by replacing the
    original label (e.g., `codex-review`) with an `-in-progress` suffix
    (e.g., `codex-review-in-progress`). When it is finished, it will swap
    the `-in-progress` label with a `-completed` one (e.g.,
    `codex-review-completed`).
    
    Users of the action are responsible for providing an `OPENAI_API_KEY`
    and making it available as a secret to the action.
  • fix: enable set positional-arguments in justfile (#1169)
    The way these definitions worked before, they did not handle quoted args
    with spaces properly.
    
    For example, if you had `/tmp/test-just/printlen.py` as:
    
    ```python
    #!/usr/bin/env python3
    
    import sys
    
    print(len(sys.argv))
    ```
    
    and your `justfile` was:
    
    ```
    printlen *args:
        /tmp/test-just/printlen.py {{args}}
    ```
    
    Then:
    
    ```shell
    $ just printlen foo bar
    3
    $ just printlen 'foo bar'
    3
    ```
    
    which is not what we want: `'foo bar'` should be treated as one
    argument.
    
    The fix is to use
    [positional-arguments](https://github.com/casey/just/blob/515e806b5121a4696113ef15b5f0b12e69854570/README.md#L1131):
    
    ```
    set positional-arguments
    
    printlen *args:
        /tmp/test-just/printlen.py "$@"
    ```
