make sure if the Sandbox has to re-initialize with different Sandbox
user SID, it still finds/updates the firewall rule instead of creating a
new one.

-# openai/codex-action
-
-`openai/codex-action` is a GitHub Action that facilitates the use of [Codex](https://github.com/openai/codex) on GitHub issues and pull requests. Using the action, associate **labels** to run Codex with the appropriate prompt for the given context. Codex will respond by posting comments or creating PRs, whichever you specify!
-
-Here is a sample workflow that uses `openai/codex-action`:
-
-```yaml
-name: Codex
-
-on:
-  issues:
-    types: [opened, labeled]
-  pull_request:
-    branches: [main]
-    types: [labeled]
-
-jobs:
-  codex:
-    if: ... # optional, but can be effective in conserving CI resources
-    runs-on: ubuntu-latest
-    # TODO(mbolin): Need to verify if/when `write` is necessary.
-    permissions:
-      contents: write
-      issues: write
-      pull-requests: write
-    steps:
-      # By default, Codex runs network disabled using --full-auto, so perform
-      # any setup that requires network (such as installing dependencies)
-      # before openai/codex-action.
-      - name: Checkout repository
-        uses: actions/checkout@v4
-
-      - name: Run Codex
-        uses: openai/codex-action@latest
-        with:
-          openai_api_key: ${{ secrets.CODEX_OPENAI_API_KEY }}
-          github_token: ${{ secrets.GITHUB_TOKEN }}
-```
-
-See sample usage in [`codex.yml`](../../workflows/codex.yml).
-
-## Triggering the Action
-
-Using the sample workflow above, we have:
-
-```yaml
-on:
-  issues:
-    types: [opened, labeled]
-  pull_request:
-    branches: [main]
-    types: [labeled]
-```
-
-which means our workflow will be triggered when any of the following events occur:
-
-- a label is added to an issue
-- a label is added to a pull request against the `main` branch
-
-### Label-Based Triggers
-
-To define a GitHub label that should trigger Codex, create a file named `.github/codex/labels/LABEL-NAME.md` in your repository where `LABEL-NAME` is the name of the label. The content of the file is the prompt template to use when the label is added (see more on [Prompt Template Variables](#prompt-template-variables) below).
-
-For example, if the file `.github/codex/labels/codex-review.md` exists, then:
-
-- Adding the `codex-review` label will trigger the workflow containing the `openai/codex-action` GitHub Action.
-- When `openai/codex-action` starts, it will replace the `codex-review` label with `codex-review-in-progress`.
-- When `openai/codex-action` is finished, it will replace the `codex-review-in-progress` label with `codex-review-completed`.
-
-If Codex sees that either `codex-review-in-progress` or `codex-review-completed` is already present, it will not perform the action.
-
-As determined by the [default config](./src/default-label-config.ts), Codex will act on the following labels by default:
-
-- Adding the `codex-review` label to a pull request will have Codex review the PR and add it to the PR as a comment.
-- Adding the `codex-triage` label to an issue will have Codex investigate the issue and report its findings as a comment.
-- Adding the `codex-issue-fix` label to an issue will have Codex attempt to fix the issue and create a PR wit the fix, if any.
-
-## Action Inputs
-
-The `openai/codex-action` GitHub Action takes the following inputs
-
-### `openai_api_key` (required)
-
-Set your `OPENAI_API_KEY` as a [repository secret](https://docs.github.com/en/actions/security-for-github-actions/security-guides/using-secrets-in-github-actions). See **Secrets and varaibles** then **Actions** in the settings for your GitHub repo.
-
-Note that the secret name does not have to be `OPENAI_API_KEY`. For example, you might want to name it `CODEX_OPENAI_API_KEY` and then configure it on `openai/codex-action` as follows:
-
-```yaml
-openai_api_key: ${{ secrets.CODEX_OPENAI_API_KEY }}
-```
-
-### `github_token` (required)
-
-This is required so that Codex can post a comment or create a PR. Set this value on the action as follows:
-
-```yaml
-github_token: ${{ secrets.GITHUB_TOKEN }}
-```
-
-### `codex_args`
-
-A whitespace-delimited list of arguments to pass to Codex. Defaults to `--full-auto`, but if you want to override the default model to use `o3`:
-
-```yaml
-codex_args: "--full-auto --model o3"
-```
-
-For more complex configurations, use the `codex_home` input.
-
-### `codex_home`
-
-If set, the value to use for the `$CODEX_HOME` environment variable when running Codex. As explained [in the docs](https://github.com/openai/codex/tree/main/codex-rs#readme), this folder can contain the `config.toml` to configure Codex, custom instructions, and log files.
-
-This should be a relative path within your repo.
-
-## Prompt Template Variables
-
-As shown above, `"prompt"` and `"promptPath"` are used to define prompt templates that will be populated and passed to Codex in response to certain events. All template variables are of the form `{CODEX_ACTION_...}` and the supported values are defined below.
-
-### `CODEX_ACTION_ISSUE_TITLE`
-
-If the action was triggered on a GitHub issue, this is the issue title.
-
-Specifically it is read as the `.issue.title` from the `$GITHUB_EVENT_PATH`.
-
-### `CODEX_ACTION_ISSUE_BODY`
-
-If the action was triggered on a GitHub issue, this is the issue body.
-
-Specifically it is read as the `.issue.body` from the `$GITHUB_EVENT_PATH`.
-
-### `CODEX_ACTION_GITHUB_EVENT_PATH`
-
-The value of the `$GITHUB_EVENT_PATH` environment variable, which is the path to the file that contains the JSON payload for the event that triggered the workflow. Codex can use `jq` to read only the fields of interest from this file.
-
-### `CODEX_ACTION_PR_DIFF`
-
-If the action was triggered on a pull request, this is the diff between the base and head commits of the PR. It is the output from `git diff`.
-
-Note that the content of the diff could be quite large, so is generally safer to point Codex at `CODEX_ACTION_GITHUB_EVENT_PATH` and let it decide how it wants to explore the change.

+You are an assistant that triages new GitHub issues by identifying potential duplicates.
+
+You will receive the following JSON files located in the current working directory:
+- `codex-current-issue.json`: JSON object describing the newly created issue (fields: number, title, body).
+- `codex-existing-issues.json`: JSON array of recent issues (each element includes number, title, body, createdAt).
+
+Instructions:
+- Load both files as JSON and review their contents carefully. The codex-existing-issues.json file is large, ensure you explore all of it.
+- Compare the current issue against the existing issues to find up to five that appear to describe the same underlying problem or request.
+- Only consider an issue a potential duplicate if there is a clear overlap in symptoms, feature requests, reproduction steps, or error messages.
+- Prioritize newer issues when similarity is comparable.
+- Ignore pull requests and issues whose similarity is tenuous.
+- When unsure, prefer returning fewer matches.
+
+Output requirements:
+- Respond with a JSON array of issue numbers (integers), ordered from most likely duplicate to least.
+- Include at most five numbers.
+- If you find no plausible duplicates, respond with `[]`.

+Labels to apply:
+1. bug — Reproducible defects in Codex products (CLI, VS Code extension, web, auth).
+2. enhancement — Feature requests or usability improvements that ask for new capabilities, better ergonomics, or quality-of-life tweaks.
+3. extension — VS Code (or other IDE) extension-specific issues.
+4. windows-os — Bugs or friction specific to Windows environments (PowerShell behavior, path handling, copy/paste, OS-specific auth or tooling failures).
+5. mcp — Topics involving Model Context Protocol servers/clients.
+6. codex-web — Issues targeting the Codex web UI/Cloud experience.
+8. azure — Problems or requests tied to Azure OpenAI deployments.
+9. documentation — Updates or corrections needed in docs/README/config references (broken links, missing examples, outdated keys, clarification requests).

+            Follow these rules:
+
+            - Add one (and only one) of the following three labels to distinguish the type of issue. Default to "bug" if unsure.
+            1. bug — Reproducible defects in Codex products (CLI, VS Code extension, web, auth).
+            2. enhancement — Feature requests or usability improvements that ask for new capabilities, better ergonomics, or quality-of-life tweaks.
+            3. documentation — Updates or corrections needed in docs/README/config references (broken links, missing examples, outdated keys, clarification requests).
+
+            - If applicable, add one of the following labels to specify which sub-product or product surface the issue relates to.
+            1. CLI — the Codex command line interface.
+            2. extension — VS Code (or other IDE) extension-specific issues.
+            3. codex-web — Issues targeting the Codex web UI/Cloud experience.
+            4. github-action — Issues with the Codex GitHub action.
+            5. iOS — Issues with the Codex iOS app.
+
+            - Additionally add zero or more of the following labels that are relevant to the issue content. Prefer a small set of precise labels over many broad ones.
+            1. windows-os — Bugs or friction specific to Windows environments (always when PowerShell is mentioned, path handling, copy/paste, OS-specific auth or tooling failures).
+            2. mcp — Topics involving Model Context Protocol servers/clients.
+            3. mcp-server — Problems related to the codex mcp-server command, where codex runs as an MCP server.
+            4. azure — Problems or requests tied to Azure OpenAI deployments.
+            5. model-behavior — Undesirable LLM behavior: forgetting goals, refusing work, hallucinating environment details, quota misreports, or other reasoning/performance anomalies.
+            6. code-review — Issues related to the code review feature or functionality.
+            7. auth - Problems related to authentication, login, or access tokens.
+            8. codex-exec - Problems related to the "codex exec" command or functionality.
+            9. context-management - Problems related to compaction, context windows, or available context reporting.
+            10. custom-model - Problems that involve using custom model providers, local models, or OSS models.
+            11. rate-limits - Problems related to token limits, rate limits, or token usage reporting.
+            12. sandbox - Issues related to local sandbox environments or tool call approvals to override sandbox restrictions.
+            13. tool-calls - Problems related to specific tool call invocations including unexpected errors, failures, or hangs.
+            14. TUI - Problems with the terminal user interface (TUI) including keyboard shortcuts, copy & pasting, menus, or screen update issues.

 - Never add or modify any code related to `CODEX_SANDBOX_NETWORK_DISABLED_ENV_VAR` or `CODEX_SANDBOX_ENV_VAR`.
   - You operate in a sandbox where `CODEX_SANDBOX_NETWORK_DISABLED=1` will be set whenever you use the `shell` tool. Any existing code that uses `CODEX_SANDBOX_NETWORK_DISABLED_ENV_VAR` was authored with this fact in mind. It is often used to early exit out of tests that the author knew you would not be able to run given your sandbox limitations.
   - Similarly, when you spawn a process using Seatbelt (`/usr/bin/sandbox-exec`), `CODEX_SANDBOX=seatbelt` will be set on the child process. Integration tests that want to run Seatbelt themselves cannot be run under Seatbelt, so checks for `CODEX_SANDBOX=seatbelt` are also often used to early exit out of tests, as appropriate.

-## Snapshot tests
+### TUI Styling (ratatui)
+
+- Prefer Stylize helpers: use "text".dim(), .bold(), .cyan(), .italic(), .underlined() instead of manual Style where possible.
+- Prefer simple conversions: use "text".into() for spans and vec![…].into() for lines; when inference is ambiguous (e.g., Paragraph::new/Cell::from), use Line::from(spans) or Span::from(text).
+- Computed styles: if the Style is computed at runtime, using `Span::styled` is OK (`Span::from(text).set_style(style)` is also acceptable).
+- Avoid hardcoded white: do not use `.white()`; prefer the default foreground (no color).
+- Chaining: combine helpers by chaining for readability (e.g., url.cyan().underlined()).
+- Single items: prefer "text".into(); use Line::from(text) or Span::from(text) only when the target type isn’t obvious from context, or when using .into() would require extra type annotations.
+- Building lines: use vec![…].into() to construct a Line when the target type is obvious and no extra type annotations are needed; otherwise use Line::from(vec![…]).
+- Avoid churn: don’t refactor between equivalent forms (Span::styled ↔ set_style, Line::from ↔ .into()) without a clear readability or functional gain; follow file‑local conventions and do not introduce type annotations solely to satisfy .into().
+- Compactness: prefer the form that stays on one line after rustfmt; if only one of Line::from(vec![…]) or vec![…].into() avoids wrapping, choose that. If both wrap, pick the one with fewer wrapped lines.
+
+### Text wrapping
+
+- Always use textwrap::wrap to wrap plain strings.
+- If you have a ratatui Line and you want to wrap it, use the helpers in tui/src/wrapping.rs, e.g. word_wrap_lines / word_wrap_line.
+- If you need to indent wrapped lines, use the initial_indent / subsequent_indent options from RtOptions if you can, rather than writing custom logic.
+- If you have a list of lines and you need to prefix them all with some prefix (optionally different on the first vs subsequent lines), use the `prefix_lines` helper from line_utils.

   - `cargo insta accept -p codex-tui`
 
 If you don’t have the tool:
+
 - `cargo install cargo-insta`
+
+### Test assertions
+
+- Tests should use pretty_assertions::assert_eq for clearer diffs. Import this at the top of the test module if it isn't already.
+- Prefer deep equals comparisons whenever possible. Perform `assert_eq!()` on entire objects, rather than individual fields.
+- Avoid mutating process environment in tests; prefer passing environment-derived flags or dependencies from above.
+
+### Spawning workspace binaries in tests (Cargo vs Buck2)
+
+- Prefer `codex_utils_cargo_bin::cargo_bin("...")` over `assert_cmd::Command::cargo_bin(...)` or `escargot` when tests need to spawn first-party binaries.
+  - Under Buck2, `CARGO_BIN_EXE_*` may be project-relative (e.g. `buck-out/...`), which breaks if a test changes its working directory. `codex_utils_cargo_bin::cargo_bin` resolves to an absolute path first.
+- When locating fixture files under Buck2, avoid `env!("CARGO_MANIFEST_DIR")` (Buck codegen sets it to `"."`). Prefer deriving paths from `codex_utils_cargo_bin::buck_project_root()` when needed.
+
+### Integration tests (core)
+
+- Prefer the utilities in `core_test_support::responses` when writing end-to-end Codex tests.
+
+- All `mount_sse*` helpers return a `ResponseMock`; hold onto it so you can assert against outbound `/responses` POST bodies.
+- Use `ResponseMock::single_request()` when a test should only issue one POST, or `ResponseMock::requests()` to inspect every captured `ResponsesRequest`.
+- `ResponsesRequest` exposes helpers (`body_json`, `input`, `function_call_output`, `custom_tool_call_output`, `call_output`, `header`, `path`, `query_param`) so assertions can target structured payloads instead of manual JSON digging.
+- Build SSE payloads with the provided `ev_*` constructors and the `sse(...)`.
+- Prefer `wait_for_event` over `wait_for_event_with_timeout`.
+- Prefer `mount_sse_once` over `mount_sse_once_match` or `mount_sse_sequence`
+
+- Typical pattern:
+
+  ```rust
+  let mock = responses::mount_sse_once(&server, responses::sse(vec![
+      responses::ev_response_created("resp-1"),
+      responses::ev_function_call(call_id, "shell", &serde_json::to_string(&args)?),
+      responses::ev_completed("resp-1"),
+  ])).await;
+
+  codex.submit(Op::UserTurn { ... }).await?;
+
+  // Assert request body if needed.
+  let request = mock.single_request();
+  // assert using request.function_call_output(call_id) or request.json_body() or other helpers.
+  ```

-  </p>
+Run `codex` and select **Sign in with ChatGPT**. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. [Learn more about what's included in your ChatGPT plan](https://help.openai.com/en/articles/11369540-codex-in-chatgpt).
 
-Run `codex` and select **Sign in with ChatGPT**. You'll need a Plus, Pro, or Team ChatGPT account, and will get access to our latest models, including `gpt-5`, at no extra cost to your plan. (Enterprise is coming soon.)
+You can also use Codex with an API key, but this requires [additional setup](https://developers.openai.com/codex/auth#sign-in-with-an-api-key).
 
-> Important: If you've used the Codex CLI before, follow these steps to migrate from usage-based billing with your API key:
->
-> 1. Update the CLI and ensure `codex --version` is `0.20.0` or later
-> 2. Delete `~/.codex/auth.json` (this should be `C:\Users\USERNAME\.codex\auth.json` on Windows)
-> 3. Run `codex login` again
+## Docs
 
-If you encounter problems with the login flow, please comment on [this issue](https://github.com/openai/codex/issues/1243).
-
-### Connecting on a "Headless" Machine
-
-Today, the login process entails running a server on `localhost:1455`. If you are on a "headless" server, such as a Docker container or are `ssh`'d into a remote machine, loading `localhost:1455` in the browser on your local machine will not automatically connect to the webserver running on the _headless_ machine, so you must use one of the following workarounds:
-
-#### Authenticate locally and copy your credentials to the "headless" machine
-
-The easiest solution is likely to run through the `codex login` process on your local machine such that `localhost:1455` _is_ accessible in your web browser. When you complete the authentication process, an `auth.json` file should be available at `$CODEX_HOME/auth.json` (on Mac/Linux, `$CODEX_HOME` defaults to `~/.codex` whereas on Windows, it defaults to `%USERPROFILE%\.codex`).
-
-Because the `auth.json` file is not tied to a specific host, once you complete the authentication flow locally, you can copy the `$CODEX_HOME/auth.json` file to the headless machine and then `codex` should "just work" on that machine. Note to copy a file to a Docker container, you can do:
-
-```shell
-# substitute MY_CONTAINER with the name or id of your Docker container:
-CONTAINER_HOME=$(docker exec MY_CONTAINER printenv HOME)
-docker exec MY_CONTAINER mkdir -p "$CONTAINER_HOME/.codex"
-docker cp auth.json MY_CONTAINER:"$CONTAINER_HOME/.codex/auth.json"
-```
-
-whereas if you are `ssh`'d into a remote machine, you likely want to use [`scp`](https://en.wikipedia.org/wiki/Secure_copy_protocol):
-
-```shell
-ssh user@remote 'mkdir -p ~/.codex'
-scp ~/.codex/auth.json user@remote:~/.codex/auth.json
-```
-
-or try this one-liner:
-
-```shell
-ssh user@remote 'mkdir -p ~/.codex && cat > ~/.codex/auth.json' < ~/.codex/auth.json
-```
-
-#### Connecting through VPS or remote
-
-If you run Codex on a remote machine (VPS/server) without a local browser, the login helper starts a server on `localhost:1455` on the remote host. To complete login in your local browser, forward that port to your machine before starting the login flow:
-
-```bash
-# From your local machine
-ssh -L 1455:localhost:1455 <user>@<remote-host>
-```
-
-Then, in that SSH session, run `codex` and select "Sign in with ChatGPT". When prompted, open the printed URL (it will be `http://localhost:1455/...`) in your local browser. The traffic will be tunneled to the remote server.
-
-### Usage-based billing alternative: Use an OpenAI API key
-
-If you prefer to pay-as-you-go, you can still authenticate with your OpenAI API key by setting it as an environment variable:
-
-```shell
-export OPENAI_API_KEY="your-api-key-here"
-```
-
-Notes:
-
-- This command only sets the key for your current terminal session, which we recommend. To set it for all future sessions, you can also add the `export` line to your shell's configuration file (e.g., `~/.zshrc`).
-- If you have signed in with ChatGPT, Codex will default to using your ChatGPT credits. If you wish to use your API key, use the `/logout` command to clear your ChatGPT authentication.
-
-#### Forcing a specific auth method (advanced)
-
-You can explicitly choose which authentication Codex should prefer when both are available.
-
-- To always use your API key (even when ChatGPT auth exists), set:
-
-```toml
-# ~/.codex/config.toml
-preferred_auth_method = "apikey"
-```
-
-Or override ad-hoc via CLI:
-
-```bash
-codex --config preferred_auth_method="apikey"
-```
-
-- To prefer ChatGPT auth (default), set:
-
-```toml
-# ~/.codex/config.toml
-preferred_auth_method = "chatgpt"
-```
-
-Notes:
-
-- When `preferred_auth_method = "apikey"` and an API key is available, the login screen is skipped.
-- When `preferred_auth_method = "chatgpt"` (default), Codex prefers ChatGPT auth if present; if only an API key is present, it will use the API key. Certain account types may also require API-key mode.
-
-### Choosing Codex's level of autonomy
-
-We always recommend running Codex in its default sandbox that gives you strong guardrails around what the agent can do. The default sandbox prevents it from editing files outside its workspace, or from accessing the network.
-
-When you launch Codex in a new folder, it detects whether the folder is version controlled and recommends one of two levels of autonomy:
-
-#### **1. Read/write**
-
-- Codex can run commands and write files in the workspace without approval.
-- To write files in other folders, access network, update git or perform other actions protected by the sandbox, Codex will need your permission.
-- By default, the workspace includes the current directory, as well as temporary directories like `/tmp`. You can see what directories are in the workspace with the `/status` command. See the docs for how to customize this behavior.
-- Advanced: You can manually specify this configuration by running `codex --sandbox workspace-write --ask-for-approval on-request`
-- This is the recommended default for version-controlled folders.
-
-#### **2. Read-only**
-
-- Codex can run read-only commands without approval.
-- To edit files, access network, or perform other actions protected by the sandbox, Codex will need your permission.
-- Advanced: You can manually specify this configuration by running `codex --sandbox read-only --ask-for-approval on-request`
-- This is the recommended default non-version-controlled folders.
-
-#### **3. Advanced configuration**
-
-Codex gives you fine-grained control over the sandbox with the `--sandbox` option, and over when it requests approval with the `--ask-for-approval` option. Run `codex help` for more on these options.
-
-#### Can I run without ANY approvals?
-
-Yes, run codex non-interactively with `--ask-for-approval never`. This option works with all `--sandbox` options, so you still have full control over Codex's level of autonomy. It will make its best attempt with whatever contrainsts you provide. For example:
-
-- Use `codex --ask-for-approval never --sandbox read-only` when you are running many agents to answer questions in parallel in the same workspace.
-- Use `codex --ask-for-approval never --sandbox workspace-write` when you want the agent to non-interactively take time to produce the best outcome, with strong guardrails around its behavior.
-- Use `codex --ask-for-approval never --sandbox danger-full-access` to dangerously give the agent full autonomy. Because this disables important safety mechanisms, we recommend against using this unless running Codex in an isolated environment.
-
-#### Fine-tuning in `config.toml`
-
-```toml
-# approval mode
-approval_policy = "untrusted"
-sandbox_mode    = "read-only"
-
-# full-auto mode
-approval_policy = "on-request"
-sandbox_mode    = "workspace-write"
-
-# Optional: allow network in workspace-write mode
-[sandbox_workspace_write]
-network_access = true
-```
-
-You can also save presets as **profiles**:
-
-```toml
-[profiles.full_auto]
-approval_policy = "on-request"
-sandbox_mode    = "workspace-write"
-
-[profiles.readonly_quiet]
-approval_policy = "never"
-sandbox_mode    = "read-only"
-```
-
-### Example prompts
-
-Below are a few bite-size examples you can copy-paste. Replace the text in quotes with your own task. See the [prompting guide](https://github.com/openai/codex/blob/main/codex-cli/examples/prompting_guide.md) for more tips and usage patterns.
-
-| ✨  | What you type                                                                   | What happens                                                               |
-| --- | ------------------------------------------------------------------------------- | -------------------------------------------------------------------------- |
-| 1   | `codex "Refactor the Dashboard component to React Hooks"`                       | Codex rewrites the class component, runs `npm test`, and shows the diff.   |
-| 2   | `codex "Generate SQL migrations for adding a users table"`                      | Infers your ORM, creates migration files, and runs them in a sandboxed DB. |
-| 3   | `codex "Write unit tests for utils/date.ts"`                                    | Generates tests, executes them, and iterates until they pass.              |
-| 4   | `codex "Bulk-rename *.jpeg -> *.jpg with git mv"`                               | Safely renames files and updates imports/usages.                           |
-| 5   | `codex "Explain what this regex does: ^(?=.*[A-Z]).{8,}$"`                      | Outputs a step-by-step human explanation.                                  |
-| 6   | `codex "Carefully review this repo, and propose 3 high impact well-scoped PRs"` | Suggests impactful PRs in the current codebase.                            |
-| 7   | `codex "Look for vulnerabilities and create a security review report"`          | Finds and explains security bugs.                                          |
-
-## Running with a prompt as input
-
-You can also run Codex CLI with a prompt as input:
-
-```shell
-codex "explain this codebase to me"
-```
-
-```shell
-codex --full-auto "create the fanciest todo-list app"
-```
-
-That's it - Codex will scaffold a file, run it inside a sandbox, install any
-missing dependencies, and show you the live result. Approve the changes and
-they'll be committed to your working directory.
-
-## Using Open Source Models
-
-<details>
-<summary><strong>Use <code>--profile</code> to use other models</strong></summary>
-
-Codex also allows you to use other providers that support the OpenAI Chat Completions (or Responses) API.
-
-To do so, you must first define custom [providers](./config.md#model_providers) in `~/.codex/config.toml`. For example, the provider for a standard Ollama setup would be defined as follows:
-
-```toml
-[model_providers.ollama]
-name = "Ollama"
-base_url = "http://localhost:11434/v1"
-```
-
-The `base_url` will have `/chat/completions` appended to it to build the full URL for the request.
-
-For providers that also require an `Authorization` header of the form `Bearer: SECRET`, an `env_key` can be specified, which indicates the environment variable to read to use as the value of `SECRET` when making a request:
-
-```toml
-[model_providers.openrouter]
-name = "OpenRouter"
-base_url = "https://openrouter.ai/api/v1"
-env_key = "OPENROUTER_API_KEY"
-```
-
-Providers that speak the Responses API are also supported by adding `wire_api = "responses"` as part of the definition. Accessing OpenAI models via Azure is an example of such a provider, though it also requires specifying additional `query_params` that need to be appended to the request URL:
-
-```toml
-[model_providers.azure]
-name = "Azure"
-# Make sure you set the appropriate subdomain for this URL.
-base_url = "https://YOUR_PROJECT_NAME.openai.azure.com/openai"
-env_key = "AZURE_OPENAI_API_KEY"  # Or "OPENAI_API_KEY", whichever you use.
-# Newer versions appear to support the responses API, see https://github.com/openai/codex/pull/1321
-query_params = { api-version = "2025-04-01-preview" }
-wire_api = "responses"
-```
-
-Once you have defined a provider you wish to use, you can configure it as your default provider as follows:
-
-```toml
-model_provider = "azure"
-```
-
-> [!TIP]
-> If you find yourself experimenting with a variety of models and providers, then you likely want to invest in defining a _profile_ for each configuration like so:
-
-```toml
-[profiles.o3]
-model_provider = "azure"
-model = "o3"
-
-[profiles.mistral]
-model_provider = "ollama"
-model = "mistral"
-```
-
-This way, you can specify one command-line argument (.e.g., `--profile o3`, `--profile mistral`) to override multiple settings together.
-
-</details>
-
-Codex can run fully locally against an OpenAI-compatible OSS host (like Ollama) using the `--oss` flag:
-
-- Interactive UI:
-  - codex --oss
-- Non-interactive (programmatic) mode:
-  - echo "Refactor utils" | codex exec --oss
-
-Model selection when using `--oss`:
-
-- If you omit `-m/--model`, Codex defaults to -m gpt-oss:20b and will verify it exists locally (downloading if needed).
-- To pick a different size, pass one of:
-  - -m "gpt-oss:20b"
-  - -m "gpt-oss:120b"
-
-Point Codex at your own OSS host:
-
-- By default, `--oss` talks to http://localhost:11434/v1.
-- To use a different host, set one of these environment variables before running Codex:
-  - CODEX_OSS_BASE_URL, for example:
-    - CODEX_OSS_BASE_URL="http://my-ollama.example.com:11434/v1" codex --oss -m gpt-oss:20b
-  - or CODEX_OSS_PORT (when the host is localhost):
-    - CODEX_OSS_PORT=11434 codex --oss
-
-Advanced: you can persist this in your config instead of environment variables by overriding the built-in `oss` provider in `~/.codex/config.toml`:
-
-```toml
-[model_providers.oss]
-name = "Open Source"
-base_url = "http://my-ollama.example.com:11434/v1"
-```
-
----
-
-### Platform sandboxing details
-
-By default, Codex CLI runs code and shell commands inside a restricted sandbox to protect your system.  
-
-> [!IMPORTANT]
-> Not all tool calls are sandboxed. Specifically, **trusted Model Context Protocol (MCP) tool calls** are executed outside of the sandbox.  
-> This is intentional: MCP tools are explicitly configured and trusted by you, and they often need to connect to **external applications or services** (e.g. issue trackers, databases, messaging systems).  
-> Running them outside the sandbox allows Codex to integrate with these external systems without being blocked by sandbox restrictions.
-
-The mechanism Codex uses to implement the sandbox policy depends on your OS:
-
-- **macOS 12+** uses **Apple Seatbelt** and runs commands using `sandbox-exec` with a profile (`-p`) that corresponds to the `--sandbox` that was specified.
-- **Linux** uses a combination of Landlock/seccomp APIs to enforce the `sandbox` configuration.
-
-Note that when running Linux in a containerized environment such as Docker, sandboxing may not work if the host/container configuration does not support the necessary Landlock/seccomp APIs. In such cases, we recommend configuring your Docker container so that it provides the sandbox guarantees you are looking for and then running `codex` with `--sandbox danger-full-access` (or, more simply, the `--dangerously-bypass-approvals-and-sandbox` flag) within your container.

-
-## Memory & project docs
-
-You can give Codex extra instructions and guidance using `AGENTS.md` files. Codex looks for `AGENTS.md` files in the following places, and merges them top-down:
-
-1. `~/.codex/AGENTS.md` - personal global guidance
-2. `AGENTS.md` at repo root - shared project notes
-3. `AGENTS.md` in the current working directory - sub-folder/feature specifics
-
----
-
-## Non-interactive / CI mode
-
-Run Codex head-less in pipelines. Example GitHub Action step:
-
-```yaml
-- name: Update changelog via Codex
-  run: |
-    npm install -g @openai/codex
-    export OPENAI_API_KEY="${{ secrets.OPENAI_KEY }}"
-    codex exec --full-auto "update CHANGELOG for next release"
-```
-
-## Model Context Protocol (MCP)
-
-The Codex CLI can be configured to leverage MCP servers by defining an [`mcp_servers`](./codex-rs/config.md#mcp_servers) section in `~/.codex/config.toml`. It is intended to mirror how tools such as Claude and Cursor define `mcpServers` in their respective JSON config files, though the Codex format is slightly different since it uses TOML rather than JSON, e.g.:
-
-```toml
-# IMPORTANT: the top-level key is `mcp_servers` rather than `mcpServers`.
-[mcp_servers.server-name]
-command = "npx"
-args = ["-y", "mcp-server"]
-env = { "API_KEY" = "value" }
-```
-
-> [!TIP]
-> It is somewhat experimental, but the Codex CLI can also be run as an MCP _server_ via `codex mcp`. If you launch it with an MCP client such as `npx @modelcontextprotocol/inspector codex mcp` and send it a `tools/list` request, you will see that there is only one tool, `codex`, that accepts a grab-bag of inputs, including a catch-all `config` map for anything you might want to override. Feel free to play around with it and provide feedback via GitHub issues.
-
-## Tracing / verbose logging
-
-Because Codex is written in Rust, it honors the `RUST_LOG` environment variable to configure its logging behavior.
-
-The TUI defaults to `RUST_LOG=codex_core=info,codex_tui=info` and log messages are written to `~/.codex/log/codex-tui.log`, so you can leave the following running in a separate terminal to monitor log messages as they are written:
-
-```
-tail -F ~/.codex/log/codex-tui.log
-```
-
-By comparison, the non-interactive mode (`codex exec`) defaults to `RUST_LOG=error`, but messages are printed inline, so there is no need to monitor a separate file.
-
-See the Rust documentation on [`RUST_LOG`](https://docs.rs/env_logger/latest/env_logger/#enabling-logging) for more information on the configuration options.

-
-### DotSlash
-
-The GitHub Release also contains a [DotSlash](https://dotslash-cli.com/) file for the Codex CLI named `codex`. Using a DotSlash file makes it possible to make a lightweight commit to source control to ensure all contributors use the same version of an executable, regardless of what platform they use for development.

-## Configuration
-
-Codex supports a rich set of configuration options documented in [`codex-rs/config.md`](./codex-rs/config.md).
-
-By default, Codex loads its configuration from `~/.codex/config.toml`.
-
-Though `--config` can be used to set/override ad-hoc config values for individual invocations of `codex`.

-## FAQ
-
-<details>
-<summary>OpenAI released a model called Codex in 2021 - is this related?</summary>
-
-In 2021, OpenAI released Codex, an AI system designed to generate code from natural language prompts. That original Codex model was deprecated as of March 2023 and is separate from the CLI tool.
-
-</details>
-
-<details>
-<summary>Which models are supported?</summary>
-
-Any model available with [Responses API](https://platform.openai.com/docs/api-reference/responses). The default is `o4-mini`, but pass `--model gpt-4.1` or set `model: gpt-4.1` in your config file to override.
-
-</details>
-<details>
-<summary>Why does <code>o3</code> or <code>o4-mini</code> not work for me?</summary>
-
-It's possible that your [API account needs to be verified](https://help.openai.com/en/articles/10910291-api-organization-verification) in order to start streaming responses and seeing chain of thought summaries from the API. If you're still running into issues, please let us know!
-
-</details>
-
-<details>
-<summary>How do I stop Codex from editing my files?</summary>
-
-Codex runs model-generated commands in a sandbox. If a proposed command or file change doesn't look right, you can simply type **n** to deny the command or give the model feedback.
-
-</details>
-<details>
-<summary>Does it work on Windows?</summary>
-
-Not directly. It requires [Windows Subsystem for Linux (WSL2)](https://learn.microsoft.com/en-us/windows/wsl/install) - Codex has been tested on macOS and Linux with Node 22.
-
-</details>
-
----
-
-## Zero data retention (ZDR) usage
-
-Codex CLI **does** support OpenAI organizations with [Zero Data Retention (ZDR)](https://platform.openai.com/docs/guides/your-data#zero-data-retention) enabled. If your OpenAI organization has Zero Data Retention enabled and you still encounter errors such as:
-
-```
-OpenAI rejected the request. Error details: Status: 400, Code: unsupported_parameter, Type: invalid_request_error, Message: 400 Previous response cannot be used for this organization due to Zero Data Retention.
-```
-
-Ensure you are running `codex` with `--config disable_response_storage=true` or add this line to `~/.codex/config.toml` to avoid specifying the command line option each time:
-
-```toml
-disable_response_storage = true
-```
-
-See [the configuration documentation on `disable_response_storage`](./codex-rs/config.md#disable_response_storage) for details.

-## Codex open source fund
-
-We're excited to launch a **$1 million initiative** supporting open source projects that use Codex CLI and other OpenAI models.
-
-- Grants are awarded up to **$25,000** API credits.
-- Applications are reviewed **on a rolling basis**.
-
-**Interested? [Apply here](https://openai.com/form/codex-open-source-fund/).**
-
----
-
-## Contributing
-
-This project is under active development and the code will likely change pretty significantly.
-
-**At the moment, we only plan to prioritize reviewing external contributions for bugs or security fixes.**
-
-If you want to add a new feature or change the behavior of an existing one, please open an issue proposing the feature and get approval from an OpenAI team member before spending time building it.
-
-**New contributions that don't go through this process may be closed** if they aren't aligned with our current roadmap or conflict with other priorities/upcoming features.
-
-### Development workflow
-
-- Create a _topic branch_ from `main` - e.g. `feat/interactive-prompt`.
-- Keep your changes focused. Multiple unrelated fixes should be opened as separate PRs.
-- Following the [development setup](#development-workflow) instructions above, ensure your change is free of lint warnings and test failures.
-
-### Writing high-impact code changes
-
-1. **Start with an issue.** Open a new one or comment on an existing discussion so we can agree on the solution before code is written.
-2. **Add or update tests.** Every new feature or bug-fix should come with test coverage that fails before your change and passes afterwards. 100% coverage is not required, but aim for meaningful assertions.
-3. **Document behaviour.** If your change affects user-facing behaviour, update the README, inline help (`codex --help`), or relevant example projects.
-4. **Keep commits atomic.** Each commit should compile and the tests should pass. This makes reviews and potential rollbacks easier.
-
-### Opening a pull request
-
-- Fill in the PR template (or include similar information) - **What? Why? How?**
-- Run **all** checks locally (`cargo test && cargo clippy --tests && cargo fmt -- --config imports_granularity=Item`). CI failures that could have been caught locally slow down the process.
-- Make sure your branch is up-to-date with `main` and that you have resolved merge conflicts.
-- Mark the PR as **Ready for review** only when you believe it is in a merge-able state.
-
-### Review process
-
-1. One maintainer will be assigned as a primary reviewer.
-2. If your PR adds a new feature that was not previously discussed and approved, we may choose to close your PR (see [Contributing](#contributing)).
-3. We may ask for changes - please do not take this personally. We value the work, but we also value consistency and long-term maintainability.
-5. When there is consensus that the PR meets the bar, a maintainer will squash-and-merge.
-
-### Community values
-
-- **Be kind and inclusive.** Treat others with respect; we follow the [Contributor Covenant](https://www.contributor-covenant.org/).
-- **Assume good intent.** Written communication is hard - err on the side of generosity.
-- **Teach & learn.** If you spot something confusing, open an issue or PR with improvements.
-
-### Getting help
-
-If you run into problems setting up the project, would like feedback on an idea, or just want to say _hi_ - please open a Discussion or jump into the relevant issue. We are happy to help.
-
-Together we can make Codex CLI an incredible tool. **Happy hacking!** :rocket:
-
-### Contributor license agreement (CLA)
-
-All contributors **must** accept the CLA. The process is lightweight:
-
-1. Open your pull request.
-2. Paste the following comment (or reply `recheck` if you've signed before):
-
-   ```text
-   I have read the CLA Document and I hereby sign the CLA
-   ```
-
-3. The CLA-Assistant bot records your signature in the repo and marks the status check as passed.
-
-No special Git commands, email attachments, or commit footers required.
-
-#### Quick fixes
-
-| Scenario          | Command                                          |
-| ----------------- | ------------------------------------------------ |
-| Amend last commit | `git commit --amend -s --no-edit && git push -f` |
-
-The **DCO check** blocks merges until every commit in the PR carries the footer (with squash this is just the one).
-
-### Releasing `codex`
-
-_For admins only._
-
-Make sure you are on `main` and have no local changes. Then run:
-
-```shell
-VERSION=0.2.0  # Can also be 0.2.0-alpha.1 or any valid Rust version.
-./codex-rs/scripts/create_github_release.sh "$VERSION"
-```
-
-This will make a local commit on top of `main` with `version` set to `$VERSION` in `codex-rs/Cargo.toml` (note that on `main`, we leave the version as `version = "0.0.0"`).
-
-This will push the commit using the tag `rust-v${VERSION}`, which in turn kicks off [the release workflow](.github/workflows/rust-release.yml). This will create a new GitHub Release named `$VERSION`.
-
-If everything looks good in the generated GitHub Release, uncheck the **pre-release** box so it is the latest release.
-
-Create a PR to update [`Formula/c/codex.rb`](https://github.com/Homebrew/homebrew-core/blob/main/Formula/c/codex.rb) on Homebrew.
-

 # npm releases
 
-Run the following:
-
-To build the 0.2.x or later version of the npm module, which runs the Rust version of the CLI, build it as follows:
+Use the staging helper in the repo root to generate npm tarballs for a release. For
+example, to stage the CLI, responses proxy, and SDK packages for version `0.6.0`:
 
 ```bash
-./codex-cli/scripts/stage_rust_release.py --release-version 0.6.0
+./scripts/stage_npm_packages.py \
+  --release-version 0.6.0 \
+  --package codex \
+  --package codex-responses-api-proxy \
+  --package codex-sdk
 ```
+
+This downloads the native artifacts once, hydrates `vendor/` for each package, and writes
+tarballs to `dist/npm/`.
+
+If you need to invoke `build_npm_package.py` directly, run
+`codex-cli/scripts/install_native_deps.py` first and pass `--vendor-src` pointing to the
+directory that contains the populated `vendor/` tree.

 ## Installing Codex
 
-Today, the easiest way to install Codex is via `npm`, though we plan to publish Codex to other package managers soon.
+Today, the easiest way to install Codex is via `npm`:
 
 ```shell
-npm i -g @openai/codex@native
+npm i -g @openai/codex
 codex
 ```
 
-You can also download a platform-specific release directly from our [GitHub Releases](https://github.com/openai/codex/releases).
+You can also install via Homebrew (`brew install --cask codex`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/openai/codex/releases).
+
+## Documentation quickstart
+
+- First run with Codex? Start with [`docs/getting-started.md`](../docs/getting-started.md) (links to the walkthrough for prompts, keyboard shortcuts, and session management).
+- Want deeper control? See [`docs/config.md`](../docs/config.md) and [`docs/install.md`](../docs/install.md).
 
 ## What's new in the Rust CLI
 
-While we are [working to close the gap between the TypeScript and Rust implementations of Codex CLI](https://github.com/openai/codex/issues/1262), note that the Rust CLI has a number of features that the TypeScript CLI does not!
+The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.
 
 ### Config
 
-Codex supports a rich set of configuration options. Note that the Rust CLI uses `config.toml` instead of `config.json`. See [`config.md`](./config.md) for details.

 ### Model Context Protocol Support
 
-Codex CLI functions as an MCP client that can connect to MCP servers on startup. See the [`mcp_servers`](./config.md#mcp_servers) section in the configuration documentation for details.
+#### MCP client
 
-It is still experimental, but you can also launch Codex as an MCP _server_ by running `codex mcp`. Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
+Codex CLI functions as an MCP client that allows the Codex CLI and IDE extension to connect to MCP servers on startup. See the [`configuration documentation`](../docs/config.md#connecting-to-mcp-servers) for details.
+
+#### MCP server (experimental)
+
+Codex can be launched as an MCP _server_ by running `codex mcp-server`. This allows _other_ MCP clients to use Codex as a tool for another agent.
+
+Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
 
 ```shell
-npx @modelcontextprotocol/inspector codex mcp
+npx @modelcontextprotocol/inspector codex mcp-server
 ```
 
+Use `codex mcp` to add/list/get/remove MCP server launchers defined in `config.toml`, and `codex mcp-server` to run the MCP server directly.
+
 ### Notifications
 
-You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The [notify documentation](./config.md#notify) includes a detailed example that explains how to get desktop notifications via [terminal-notifier](https://github.com/julienXX/terminal-notifier) on macOS.

When Codex detects that it is running under WSL 2 inside Windows Terminal (`WT_SESSION` is set), the TUI automatically falls back to native Windows toast notifications so approval prompts and completed turns surface even though Windows Terminal does not implement OSC 9.
 
-### `codex exec` to run Codex programmatially/non-interactively
+### `codex exec` to run Codex programmatically/non-interactively
 
 To run Codex non-interactively, run `codex exec PROMPT` (you can also pass the prompt via `stdin`) and Codex will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
 
-### Use `@` for file search
-
-Typing `@` triggers a fuzzy-filename search over the workspace root. Use up/down to select among the results and Tab or Enter to replace the `@` with the selected path. You can use Esc to cancel the search.
-
-### `--cd`/`-C` flag
-
-Sometimes it is not convenient to `cd` to the directory you want Codex to use as the "working root" before running Codex. Fortunately, `codex` supports a `--cd` option so you can specify whatever folder you want. You can confirm that Codex is honoring `--cd` by double-checking the **workdir** it reports in the TUI at the start of a new session.
-
-### Shell completions
-
-Generate shell completion scripts via:
-
-```shell
-codex completion bash
-codex completion zsh
-codex completion fish
-```
-
 ### Experimenting with the Codex Sandbox
 
 To test to see what happens when a command is run under the sandbox provided by Codex, we provide the following subcommands in Codex CLI:
 
 ```
 # macOS
-codex debug seatbelt [--full-auto] [COMMAND]...
+codex sandbox macos [--full-auto] [--log-denials] [COMMAND]...
 
 # Linux
+codex sandbox linux [--full-auto] [COMMAND]...
+
+# Windows
+codex sandbox windows [--full-auto] [COMMAND]...
+
+# Legacy aliases
+codex debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
 codex debug landlock [--full-auto] [COMMAND]...
 ```
