 Codex CLI supports a rich set of configuration options, with preferences stored in `~/.codex/config.toml`. For full configuration options, see [Configuration](./docs/config.md).
 
-### Execpolicy Quickstart
-
-Codex can enforce your own rules-based execution policy before it runs shell commands.
-
-1. Create a policy directory: `mkdir -p ~/.codex/policy`.
-2. Create one or more `.codexpolicy` files in that folder. Codex automatically loads every `.codexpolicy` file in there on startup.
-3. Write `prefix_rule` entries to describe the commands you want to allow, prompt, or block:
-
-```starlark
-prefix_rule(
-    pattern = ["git", ["push", "fetch"]],
-    decision = "prompt",  # allow | prompt | forbidden
-    match = [["git", "push", "origin", "main"]],  # examples that must match
-    not_match = [["git", "status"]],              # examples that must not match
-)
-```
-
-- `pattern` is a list of shell tokens, evaluated from left to right; wrap tokens in a nested list to express alternatives (e.g., match both `push` and `fetch`).
-- `decision` sets the severity; Codex picks the strictest decision when multiple rules match (forbidden > prompt > allow).
-- `match` and `not_match` act as (optional) unit tests. Codex validates them when it loads your policy, so you get feedback if an example has unexpected behavior.
-
-In this example rule, if Codex wants to run commands with the prefix `git push` or `git fetch`, it will first ask for user approval.

-Use the `codex execpolicy check` subcommand to preview decisions before you save a rule (see the [`codex-execpolicy` README](./codex-rs/execpolicy/README.md) for syntax details):
-
-```shell
-codex execpolicy check --policy ~/.codex/policy/default.codexpolicy git push origin main
-```
-
-Pass multiple `--policy` flags to test how several files combine, and use `--pretty` for formatted JSON output. See the [`codex-rs/execpolicy` README](./codex-rs/execpolicy/README.md) for a more detailed walkthrough of the available syntax.
-
-## Note: `execpolicy` commands are still in preview. The API may have breaking changes in the future.

-## Lifecycle Overview
-
-- Initialize once: Immediately after launching the codex app-server process, send an `initialize` request with your client metadata, then emit an `initialized` notification. Any other request before this handshake gets rejected.
-- Start (or resume) a thread: Call `thread/start` to open a fresh conversation. The response returns the thread object and you’ll also get a `thread/started` notification. If you’re continuing an existing conversation, call `thread/resume` with its ID instead.
-- Begin a turn: To send user input, call `turn/start` with the target `threadId` and the user's input. Optional fields let you override model, cwd, sandbox policy, etc. This immediately returns the new turn object and triggers a `turn/started` notification.
-- Stream events: After `turn/start`, keep reading JSON-RPC notifications on stdout. You’ll see `item/started`, `item/completed`, deltas like `item/agentMessage/delta`, tool progress, etc. These represent streaming model output plus any side effects (commands, tool calls, reasoning notes).
-- Finish the turn: When the model is done (or the turn is interrupted via making the `turn/interrupt` call), the server sends `turn/completed` with the final turn state and token usage.
-
-## Initialization
-
-Clients must send a single `initialize` request before invoking any other method, then acknowledge with an `initialized` notification. The server returns the user agent string it will present to upstream services; subsequent requests issued before initialization receive a `"Not initialized"` error, and repeated `initialize` calls receive an `"Already initialized"` error.
-
-Example:
-
-```json
-{ "method": "initialize", "id": 0, "params": {
-    "clientInfo": { "name": "codex-vscode", "title": "Codex VS Code Extension", "version": "0.1.0" }
-} }
-{ "id": 0, "result": { "userAgent": "codex-app-server/0.1.0 codex-vscode/0.1.0" } }
-{ "method": "initialized" }
-```
-
-## Core primitives
-
-We have 3 top level primitives:
-- Thread - a conversation between the Codex agent and a user. Each thread contains multiple turns.
-- Turn - one turn of the conversation, typically starting with a user message and finishing with an agent message. Each turn contains multiple items.
-- Item - represents user inputs and agent outputs as part of the turn, persisted and used as the context for future conversations.
-
-## Thread & turn endpoints
-
-The JSON-RPC API exposes dedicated methods for managing Codex conversations. Threads store long-lived conversation metadata, and turns store the per-message exchange (input → Codex output, including streamed items). Use the thread APIs to create, list, or archive sessions, then drive the conversation with turn APIs and notifications.
-
-### Quick reference
-- `thread/start` — create a new thread; emits `thread/started` and auto-subscribes you to turn/item events for that thread.
-- `thread/resume` — reopen an existing thread by id so subsequent `turn/start` calls append to it.
-- `thread/list` — page through stored rollouts; supports cursor-based pagination and optional `modelProviders` filtering.
-- `thread/archive` — move a thread’s rollout file into the archived directory; returns `{}` on success.
-- `turn/start` — add user input to a thread and begin Codex generation; responds with the initial `turn` object and streams `turn/started`, `item/*`, and `turn/completed` notifications.
-- `turn/interrupt` — request cancellation of an in-flight turn by `(thread_id, turn_id)`; success is an empty `{}` response and the turn finishes with `status: "interrupted"`.
-- `review/start` — kick off Codex’s automated reviewer for a thread; responds like `turn/start` and emits a `item/completed` notification with a `codeReview` item when results are ready.

-{ "method": "thread/start", "id": 10, "params": {
-    // Optionally set config settings. If not specified, will use the user's
-    // current config settings.
-    "model": "gpt-5.1-codex",
-    "cwd": "/Users/me/project",
-    "approvalPolicy": "never",
-    "sandbox": "workspaceWrite",
-} }
-{ "id": 10, "result": {
-    "thread": {
-        "id": "thr_123",
-        "preview": "",
-        "modelProvider": "openai",
-        "createdAt": 1730910000
-    }
-} }
-{ "method": "thread/started", "params": { "thread": { … } } }
-```
-
-To continue a stored session, call `thread/resume` with the `thread.id` you previously recorded. The response shape matches `thread/start`, and no additional notifications are emitted:
-
-```json
-{ "method": "thread/resume", "id": 11, "params": { "threadId": "thr_123" } }
-{ "id": 11, "result": { "thread": { "id": "thr_123", … } } }
-```
-
-### 2) List threads (pagination & filters)
-
-`thread/list` lets you render a history UI. Pass any combination of:
-- `cursor` — opaque string from a prior response; omit for the first page.
-- `limit` — server defaults to a reasonable page size if unset.
-- `modelProviders` — restrict results to specific providers; unset, null, or an empty array will include all providers.
-
-Example:
-
-```json
-{ "method": "thread/list", "id": 20, "params": {
-    "cursor": null,
-    "limit": 25,
-} }
-{ "id": 20, "result": {
-    "data": [
-        { "id": "thr_a", "preview": "Create a TUI", "modelProvider": "openai", "createdAt": 1730831111 },
-        { "id": "thr_b", "preview": "Fix tests", "modelProvider": "openai", "createdAt": 1730750000 }
-    ],
-    "nextCursor": "opaque-token-or-null"
-} }
-```
-
-When `nextCursor` is `null`, you’ve reached the final page.
-
-### 3) Archive a thread
-
-Use `thread/archive` to move the persisted rollout (stored as a JSONL file on disk) into the archived sessions directory.
-
-```json
-{ "method": "thread/archive", "id": 21, "params": { "threadId": "thr_b" } }
-{ "id": 21, "result": {} }
-```
-
-An archived thread will not appear in future calls to `thread/list`.
-
-### 4) Start a turn (send user input)
-
-Turns attach user input (text or images) to a thread and trigger Codex generation. The `input` field is a list of discriminated unions:
-
-- `{"type":"text","text":"Explain this diff"}`
-- `{"type":"image","url":"https://…png"}`
-- `{"type":"localImage","path":"/tmp/screenshot.png"}`
-
-You can optionally specify config overrides on the new turn. If specified, these settings become the default for subsequent turns on the same thread.
-
-```json
-{ "method": "turn/start", "id": 30, "params": {
-    "threadId": "thr_123",
-    "input": [ { "type": "text", "text": "Run tests" } ],
-    // Below are optional config overrides
-    "cwd": "/Users/me/project",
-    "approvalPolicy": "unlessTrusted",
-    "sandboxPolicy": {
-        "mode": "workspaceWrite",
-        "writableRoots": ["/Users/me/project"],
-        "networkAccess": true
-    },
-    "model": "gpt-5.1-codex",
-    "effort": "medium",
-    "summary": "concise"
-} }
-{ "id": 30, "result": { "turn": {
-    "id": "turn_456",
-    "status": "inProgress",
-    "items": [],
-    "error": null
-} } }
-```
-
-### 5) Interrupt an active turn
-
-You can cancel a running Turn with `turn/interrupt`.
-
-```json
-{ "method": "turn/interrupt", "id": 31, "params": {
-    "threadId": "thr_123",
-    "turnId": "turn_456"
-} }
-{ "id": 31, "result": {} }
-```
-
-The server requests cancellations for running subprocesses, then emits a `turn/completed` event with `status: "interrupted"`. Rely on the `turn/completed` to know when Codex-side cleanup is done.
-
-### 6) Request a code review
-
-Use `review/start` to run Codex’s reviewer on the currently checked-out project. The request takes the thread id plus a `target` describing what should be reviewed:
-
-- `{"type":"uncommittedChanges"}` — staged, unstaged, and untracked files.
-- `{"type":"baseBranch","branch":"main"}` — diff against the provided branch’s upstream (see prompt for the exact `git merge-base`/`git diff` instructions Codex will run).
-- `{"type":"commit","sha":"abc1234","title":"Optional subject"}` — review a specific commit.
-- `{"type":"custom","instructions":"Free-form reviewer instructions"}` — fallback prompt equivalent to the legacy manual review request.
-- `appendToOriginalThread` (bool, default `false`) — when `true`, Codex also records a final assistant-style message with the review summary in the original thread. When `false`, only the `codeReview` item is emitted for the review run and no extra message is added to the original thread.
-
-Example request/response:
-
-```json
-{ "method": "review/start", "id": 40, "params": {
-    "threadId": "thr_123",
-    "appendToOriginalThread": true,
-    "target": { "type": "commit", "sha": "1234567deadbeef", "title": "Polish tui colors" }
-} }
-{ "id": 40, "result": { "turn": {
-    "id": "turn_900",
-    "status": "inProgress",
-    "items": [
-        { "type": "userMessage", "id": "turn_900", "content": [ { "type": "text", "text": "Review commit 1234567: Polish tui colors" } ] }
-    ],
-    "error": null
-} } }
-```
-
-Codex streams the usual `turn/started` notification followed by an `item/started`
-with the same `codeReview` item id so clients can show progress:
-
-```json
-{ "method": "item/started", "params": { "item": {
-    "type": "codeReview",
-    "id": "turn_900",
-    "review": "current changes"
-} } }
-```
-
-When the reviewer finishes, the server emits `item/completed` containing the same
-`codeReview` item with the final review text:
-
-```json
-{ "method": "item/completed", "params": { "item": {
-    "type": "codeReview",
-    "id": "turn_900",
-    "review": "Looks solid overall...\n\n- Prefer Stylize helpers — app.rs:10-20\n  ..."
-} } }
-```
-
-The `review` string is plain text that already bundles the overall explanation plus a bullet list for each structured finding (matching `ThreadItem::CodeReview` in the generated schema). Use this notification to render the reviewer output in your client.
-
-## Auth endpoints
-
-The JSON-RPC auth/account surface exposes request/response methods plus server-initiated notifications (no `id`). Use these to determine auth state, start or cancel logins, logout, and inspect ChatGPT rate limits.
-
-### Quick reference
-- `account/read` — fetch current account info; optionally refresh tokens.
-- `account/login/start` — begin login (`apiKey` or `chatgpt`).
-- `account/login/completed` (notify) — emitted when a login attempt finishes (success or error).
-- `account/login/cancel` — cancel a pending ChatGPT login by `loginId`.
-- `account/logout` — sign out; triggers `account/updated`.
-- `account/updated` (notify) — emitted whenever auth mode changes (`authMode`: `apikey`, `chatgpt`, or `null`).
-- `account/rateLimits/read` — fetch ChatGPT rate limits; updates arrive via `account/rateLimits/updated` (notify).
-
-### 1) Check auth state
-
-Request:
-```json
-{ "method": "account/read", "id": 1, "params": { "refreshToken": false } }
-```
-
-Response examples:
-```json
-{ "id": 1, "result": { "account": null, "requiresOpenaiAuth": false } } // No OpenAI auth needed (e.g., OSS/local models)
-{ "id": 1, "result": { "account": null, "requiresOpenaiAuth": true } }  // OpenAI auth required (typical for OpenAI-hosted models)
-{ "id": 1, "result": { "account": { "type": "apiKey" }, "requiresOpenaiAuth": true } }
-{ "id": 1, "result": { "account": { "type": "chatgpt", "email": "user@example.com", "planType": "pro" }, "requiresOpenaiAuth": true } }
-```
-
-Field notes:
-- `refreshToken` (bool): set `true` to force a token refresh.
-- `requiresOpenaiAuth` reflects the active provider; when `false`, Codex can run without OpenAI credentials.
-
-### 2) Log in with an API key
-
-1. Send:
-   ```json
-   { "method": "account/login/start", "id": 2, "params": { "type": "apiKey", "apiKey": "sk-…" } }
-   ```
-2. Expect:
-   ```json
-   { "id": 2, "result": { "type": "apiKey" } }
-   ```
-3. Notifications:
-   ```json
-   { "method": "account/login/completed", "params": { "loginId": null, "success": true, "error": null } }
-   { "method": "account/updated", "params": { "authMode": "apikey" } }
-   ```
-
-### 3) Log in with ChatGPT (browser flow)
-
-1. Start:
-   ```json
-   { "method": "account/login/start", "id": 3, "params": { "type": "chatgpt" } }
-   { "id": 3, "result": { "type": "chatgpt", "loginId": "<uuid>", "authUrl": "https://chatgpt.com/…&redirect_uri=http%3A%2F%2Flocalhost%3A<port>%2Fauth%2Fcallback" } }
-   ```
-2. Open `authUrl` in a browser; the app-server hosts the local callback.
-3. Wait for notifications:
-   ```json
-   { "method": "account/login/completed", "params": { "loginId": "<uuid>", "success": true, "error": null } }
-   { "method": "account/updated", "params": { "authMode": "chatgpt" } }
-   ```
-
-### 4) Cancel a ChatGPT login
-
-```json
-{ "method": "account/login/cancel", "id": 4, "params": { "loginId": "<uuid>" } }
-{ "method": "account/login/completed", "params": { "loginId": "<uuid>", "success": false, "error": "…" } }
-```
-
-### 5) Logout
-
-```json
-{ "method": "account/logout", "id": 5 }
-{ "id": 5, "result": {} }
-{ "method": "account/updated", "params": { "authMode": null } }
-```
-
-### 6) Rate limits (ChatGPT)
-
-```json
-{ "method": "account/rateLimits/read", "id": 6 }
-{ "id": 6, "result": { "rateLimits": { "primary": { "usedPercent": 25, "windowDurationMins": 15, "resetsAt": 1730947200 }, "secondary": null } } }
-{ "method": "account/rateLimits/updated", "params": { "rateLimits": { … } } }
-```
-
-Field notes:
-- `usedPercent` is current usage within the OpenAI quota window.
-- `windowDurationMins` is the quota window length.
-- `resetsAt` is a Unix timestamp (seconds) for the next reset.
-
-### Dev notes
-
-- `codex app-server generate-ts --out <dir>` emits v2 types under `v2/`.
-- `codex app-server generate-json-schema --out <dir>` outputs `codex_app_server_protocol.schemas.json`.
-- See [“Authentication and authorization” in the config docs](../../docs/config.md#authentication-and-authorization) for configuration knobs.
-
-
-## Events (work-in-progress)
-
-Event notifications are the server-initiated event stream for thread lifecycles, turn lifecycles, and the items within them. After you start or resume a thread, keep reading stdout for `thread/started`, `turn/*`, and `item/*` notifications.
-
-### Turn events
-
-The app-server streams JSON-RPC notifications while a turn is running. Each turn starts with `turn/started` (initial `turn`) and ends with `turn/completed` (final `turn` plus token `usage`), and clients subscribe to the events they care about, rendering each item incrementally as updates arrive. The per-item lifecycle is always: `item/started` → zero or more item-specific deltas → `item/completed`.
-
-- `turn/started` — `{ turn }` with the turn id, empty `items`, and `status: "inProgress"`.
-- `turn/completed` — `{ turn }` where `turn.status` is `completed`, `interrupted`, or `failed`; failures carry `{ error: { message, codexErrorInfo? } }`.
-
-Today both notifications carry an empty `items` array even when item events were streamed; rely on `item/*` notifications for the canonical item list until this is fixed.
-
-#### Errors
-`error` event is emitted whenever the server hits an error mid-turn (for example, upstream model errors or quota limits). Carries the same `{ error: { message, codexErrorInfo? } }` payload as `turn.status: "failed"` and may precede that terminal notification.
-
-  `codexErrorInfo` maps to the `CodexErrorInfo` enum. Common values:
-  - `ContextWindowExceeded`
-  - `UsageLimitExceeded`
-  - `HttpConnectionFailed { httpStatusCode? }`: upstream HTTP failures including 4xx/5xx
-  - `ResponseStreamConnectionFailed { httpStatusCode? }`: failure to connect to the response SSE stream
-  - `ResponseStreamDisconnected { httpStatusCode? }`: disconnect of the response SSE stream in the middle of a turn before completion
-  - `ResponseTooManyFailedAttempts { httpStatusCode? }`
-  - `BadRequest`
-  - `Unauthorized`
-  - `SandboxError`
-  - `InternalServerError`
-  - `Other`: all unclassified errors
-
-When an upstream HTTP status is available (for example, from the Responses API or a provider), it is forwarded in `httpStatusCode` on the relevant `codexErrorInfo` variant.
-
-#### Thread items
-
-`ThreadItem` is the tagged union carried in turn responses and `item/*` notifications. Currently we support events for the following items:
-- `userMessage` — `{id, content}` where `content` is a list of user inputs (`text`, `image`, or `localImage`).
-- `agentMessage` — `{id, text}` containing the accumulated agent reply.
-- `reasoning` — `{id, summary, content}` where `summary` holds streamed reasoning summaries (applicable for most OpenAI models) and `content` holds raw reasoning blocks (applicable for e.g. open source models).
-- `mcpToolCall` — `{id, server, tool, status, arguments, result?, error?}` describing MCP calls; `status` is `inProgress`, `completed`, or `failed`.
-- `webSearch` — `{id, query}` for a web search request issued by the agent.
-
-All items emit two shared lifecycle events:
-- `item/started` — emits the full `item` when a new unit of work begins so the UI can render it immediately; the `item.id` in this payload matches the `itemId` used by deltas.
-- `item/completed` — sends the final `item` once that work finishes (e.g., after a tool call or message completes); treat this as the authoritative state.
-
-There are additional item-specific events:
-#### agentMessage
-- `item/agentMessage/delta` — appends streamed text for the agent message; concatenate `delta` values for the same `itemId` in order to reconstruct the full reply.
-#### reasoning
-- `item/reasoning/summaryTextDelta` — streams readable reasoning summaries; `summaryIndex` increments when a new summary section opens.
-- `item/reasoning/summaryPartAdded` — marks the boundary between reasoning summary sections for an `itemId`; subsequent `summaryTextDelta` entries share the same `summaryIndex`.
-- `item/reasoning/textDelta` — streams raw reasoning text (only applicable for e.g. open source models); use `contentIndex` to group deltas that belong together before showing them in the UI.
