-# Containerized Development
-
-We provide the following options to facilitate Codex development in a container. This is particularly useful for verifying the Linux build when working on a macOS host.
-
-## Docker
-
-To build the Docker image locally for x64 and then run it with the repo mounted under `/workspace`:
-
-```shell
-CODEX_DOCKER_IMAGE_NAME=codex-linux-dev
-docker build --platform=linux/amd64 -t "$CODEX_DOCKER_IMAGE_NAME" ./.devcontainer
-docker run --platform=linux/amd64 --rm -it -e CARGO_TARGET_DIR=/workspace/codex-rs/target-amd64 -v "$PWD":/workspace -w /workspace/codex-rs "$CODEX_DOCKER_IMAGE_NAME"
-```
-
-Note that `/workspace/target` will contain the binaries built for your host platform, so we include `-e CARGO_TARGET_DIR=/workspace/codex-rs/target-amd64` in the `docker run` command so that the binaries built inside your container are written to a separate directory.
-
-For arm64, specify `--platform=linux/amd64` instead for both `docker build` and `docker run`.
-
-Currently, the `Dockerfile` works for both x64 and arm64 Linux, though you need to run `rustup target add x86_64-unknown-linux-musl` yourself to install the musl toolchain for x64.
-
-## VS Code
-
-VS Code recognizes the `devcontainer.json` file and gives you the option to develop Codex in a container. Currently, `devcontainer.json` builds and runs the `arm64` flavor of the container.
-
-From the integrated terminal in VS Code, you can build either flavor of the `arm64` build (GNU or musl):
-
-```shell
-cargo build --target aarch64-unknown-linux-musl
-cargo build --target aarch64-unknown-linux-gnu
-```

-Review this PR and respond with a very concise final message, formatted in Markdown.
-
-There should be a summary of the changes (1-2 sentences) and a few bullet points if necessary.
-
-Then provide the **review** (1-2 sentences plus bullet points, friendly tone).
-
-Things to look out for when doing the review:
-
-## General Principles
-
-- **Make sure the pull request body explains the motivation behind the change.** If the author has failed to do this, call it out, and if you think you can deduce the motivation behind the change, propose copy.
-- Ideally, the PR body also contains a small summary of the change. For small changes, the PR title may be sufficient.
-- Each PR should ideally do one conceptual thing. For example, if a PR does a refactoring as well as introducing a new feature, push back and suggest the refactoring be done in a separate PR. This makes things easier for the reviewer, as refactoring changes can often be far-reaching, yet quick to review.
-- When introducing new code, be on the lookout for code that duplicates existing code. When found, propose a way to refactor the existing code such that it should be reused.
-
-## Code Organization
-
-- Each crate in the Cargo workspace in `codex-rs` has a specific purpose: make a note if you believe new code is not introduced in the correct crate.
-- When possible, try to keep the `core` crate as small as possible. Non-core but shared logic is often a good candidate for `codex-rs/common`.
-- Be wary of large files and offer suggestions for how to break things into more reasonably-sized files.
-- Rust files should generally be organized such that the public parts of the API appear near the top of the file and helper functions go below. This is analogous to the "inverted pyramid" structure that is favored in journalism.
-
-## Assertions in Tests
-
-Assert the equality of the entire objects instead of doing "piecemeal comparisons," performing `assert_eq!()` on individual fields.
-
-Note that unit tests also function as "executable documentation." As shown in the following example, "piecemeal comparisons" are often more verbose, provide less coverage, and are not as useful as executable documentation.
-
-For example, suppose you have the following enum:
-
-```rust
-#[derive(Debug, PartialEq)]
-enum Message {
-    Request {
-        id: String,
-        method: String,
-        params: Option<serde_json::Value>,
-    },
-    Notification {
-        method: String,
-        params: Option<serde_json::Value>,
-    },
-}
-```
-
-This is an example of a _piecemeal_ comparison:
-
-```rust
-// BAD: Piecemeal Comparison
-
-#[test]
-fn test_get_latest_messages() {
-    let messages = get_latest_messages();
-    assert_eq!(messages.len(), 2);
-
-    let m0 = &messages[0];
-    match m0 {
-        Message::Request { id, method, params } => {
-            assert_eq!(id, "123");
-            assert_eq!(method, "subscribe");
-            assert_eq!(
-                *params,
-                Some(json!({
-                    "conversation_id": "x42z86"
-                }))
-            )
-        }
-        Message::Notification { .. } => {
-            panic!("expected Request");
-        }
-    }
-
-    let m1 = &messages[1];
-    match m1 {
-        Message::Request { .. } => {
-            panic!("expected Notification");
-        }
-        Message::Notification { method, params } => {
-            assert_eq!(method, "log");
-            assert_eq!(
-                *params,
-                Some(json!({
-                    "level": "info",
-                    "message": "subscribed"
-                }))
-            )
-        }
-    }
-}
-```
-
-This is a _deep_ comparison:
-
-```rust
-// GOOD: Verify the entire structure with a single assert_eq!().
-
-use pretty_assertions::assert_eq;
-
-#[test]
-fn test_get_latest_messages() {
-    let messages = get_latest_messages();
-
-    assert_eq!(
-        vec![
-            Message::Request {
-                id: "123".to_string(),
-                method: "subscribe".to_string(),
-                params: Some(json!({
-                    "conversation_id": "x42z86"
-                })),
-            },
-            Message::Notification {
-                method: "log".to_string(),
-                params: Some(json!({
-                    "level": "info",
-                    "message": "subscribed"
-                })),
-            },
-        ],
-        messages,
-    );

-## More Tactical Rust Things To Look Out For
-
-- Do not use `unsafe` (unless you have a really, really good reason like using an operating system API directly and no safe wrapper exists). For example, there are cases where it is tempting to use `unsafe` in order to use `std::env::set_var()`, but this indeed `unsafe` and has led to race conditions on multiple occasions. (When this happens, find a mechanism other than environment variables to use for configuration.)
-- Encourage the use of small enums or the newtype pattern in Rust if it helps readability without adding significant cognitive load or lines of code.
-- If you see opportunities for the changes in a diff to use more idiomatic Rust, please make specific recommendations. For example, favor the use of expressions over `return`.
-- When modifying a `Cargo.toml` file, make sure that dependency lists stay alphabetically sorted. Also consider whether a new dependency is added to the appropriate place (e.g., `[dependencies]` versus `[dev-dependencies]`)
-
-## Pull Request Body
-
-- If the nature of the change seems to have a visual component (which is often the case for changes to `codex-rs/tui`), recommend including a screenshot or video to demonstrate the change, if appropriate.
-- References to existing GitHub issues and PRs are encouraged, where appropriate, though you likely do not have network access, so may not be able to help here.

-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).

-            - After your analysis, validate your results in 1-2 lines explaining your decision to return the selected matches.
-            - When unsure, prefer returning fewer matches.

-            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. app - Issues related to the Codex desktop application.
-            4. codex-web — Issues targeting the Codex web UI/Cloud experience.
-            5. github-action — Issues with the Codex GitHub action.
-            6. 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.

-In the codex-rs folder where the rust code lives:
-
-- Crate names are prefixed with `codex-`. For example, the `core` folder's crate is named `codex-core`
-- When using format! and you can inline variables into {}, always do that.
-- Install any commands the repo relies on (for example `just`, `rg`, or `cargo-insta`) if they aren't already available before running instructions here.
-- 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.
-- Always collapse if statements per https://rust-lang.github.io/rust-clippy/master/index.html#collapsible_if
-- Always inline format! args when possible per https://rust-lang.github.io/rust-clippy/master/index.html#uninlined_format_args
-- Use method references over closures when possible per https://rust-lang.github.io/rust-clippy/master/index.html#redundant_closure_for_method_calls
-- When possible, make `match` statements exhaustive and avoid wildcard arms.
-- When writing tests, prefer comparing the equality of entire objects over fields one by one.
-- When making a change that adds or changes an API, ensure that the documentation in the `docs/` folder is up to date if applicable.
-- If you change `ConfigToml` or nested config types, run `just write-config-schema` to update `codex-rs/core/config.schema.json`.

-Run `just fmt` (in `codex-rs` directory) automatically after you have finished making Rust code changes; do not ask for approval to run it. Additionally, run the tests:

-1. Run the test for the specific project that was changed. For example, if changes were made in `codex-rs/tui`, run `cargo test -p codex-tui`.
-2. Once those pass, if any changes were made in common, core, or protocol, run the complete test suite with `cargo test --all-features`. project-specific or individual tests can be run without asking the user, but do ask the user before running the complete test suite.
-
-Before finalizing a large change to `codex-rs`, run `just fix -p <project>` (in `codex-rs` directory) to fix any linter issues in the code. Prefer scoping with `-p` to avoid slow workspace‑wide Clippy builds; only run `just fix` without `-p` if you changed shared crates.
-
-## TUI style conventions
-
-See `codex-rs/tui/styles.md`.
-
-## TUI code conventions
-
-- Use concise styling helpers from ratatui’s Stylize trait.
-  - Basic spans: use "text".into()
-  - Styled spans: use "text".red(), "text".green(), "text".magenta(), "text".dim(), etc.
-  - Prefer these over constructing styles with `Span::styled` and `Style` directly.
-  - Example: patch summary file lines
-    - Desired: vec!["  └ ".into(), "M".red(), " ".dim(), "tui/src/app.rs".dim()]
-
-### 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.
-
-## Tests
-
-### Snapshot tests
-
-This repo uses snapshot tests (via `insta`), especially in `codex-rs/tui`, to validate rendered output. When UI or text output changes intentionally, update the snapshots as follows:
-
-- Run tests to generate any updated snapshots:
-  - `cargo test -p codex-tui`
-- Check what’s pending:
-  - `cargo insta pending-snapshots -p codex-tui`
-- Review changes by reading the generated `*.snap.new` files directly in the repo, or preview a specific file:
-  - `cargo insta show -p codex-tui path/to/file.snap.new`
-- Only if you intend to accept all new snapshots in this crate, run:
-  - `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 Bazel)
-
-- Prefer `codex_utils_cargo_bin::cargo_bin("...")` over `assert_cmd::Command::cargo_bin(...)` or `escargot` when tests need to spawn first-party binaries.
-  - Under Bazel, binaries and resources may live under runfiles; use `codex_utils_cargo_bin::cargo_bin` to resolve absolute paths that remain stable after `chdir`.
-- When locating fixture files or test resources under Bazel, avoid `env!("CARGO_MANIFEST_DIR")`. Prefer `codex_utils_cargo_bin::find_resource!` so paths resolve correctly under both Cargo and Bazel runfiles.
-
-### 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.
-  ```
-
-## App-server API Development Best Practices
-
-These guidelines apply to app-server protocol work in `codex-rs`, especially:
-
-- `app-server-protocol/src/protocol/common.rs`
-- `app-server-protocol/src/protocol/v2.rs`
-- `app-server/README.md`
-
-### Core Rules
-
-- All active API development should happen in app-server v2. Do not add new API surface area to v1.
-- Follow payload naming consistently:
-  `*Params` for request payloads, `*Response` for responses, and `*Notification` for notifications.
-- Expose RPC methods as `<resource>/<method>` and keep `<resource>` singular (for example, `thread/read`, `app/list`).
-- Always expose fields as camelCase on the wire with `#[serde(rename_all = "camelCase")]` unless a tagged union or explicit compatibility requirement needs a targeted rename.
-- Always set `#[ts(export_to = "v2/")]` on v2 request/response/notification types so generated TypeScript lands in the correct namespace.
-- Never use `#[serde(skip_serializing_if = "Option::is_none")]` for v2 API payload fields.
-  Exception: client->server requests that intentionally have no params may use:
-  `params: #[ts(type = "undefined")] #[serde(skip_serializing_if = "Option::is_none")] Option<()>`.
-- For client->server JSON-RPC request payloads (`*Params`) only, every optional field must be annotated with `#[ts(optional = nullable)]`. Do not use `#[ts(optional = nullable)]` outside client->server request payloads (`*Params`).
-- For client->server JSON-RPC request payloads only, and you want to express a boolean field where omission means `false`, use `#[serde(default, skip_serializing_if = "std::ops::Not::not")] pub field: bool` over `Option<bool>`.
-- For new list methods, implement cursor pagination by default:
-  request fields `pub cursor: Option<String>` and `pub limit: Option<u32>`,
-  response fields `pub data: Vec<...>` and `pub next_cursor: Option<String>`.
-- Keep Rust and TS wire renames aligned. If a field or variant uses `#[serde(rename = "...")]`, add matching `#[ts(rename = "...")]`.
-- For discriminated unions, use explicit tagging in both serializers:
-  `#[serde(tag = "type", ...)]` and `#[ts(tag = "type", ...)]`.
-- Prefer plain `String` IDs at the API boundary (do UUID parsing/conversion internally if needed).
-- Timestamps should be integer Unix seconds (`i64`) and named `*_at` (for example, `created_at`, `updated_at`, `resets_at`).
-- For experimental API surface area:
-  use `#[experimental("method/or/field")]`, derive `ExperimentalApi` when field-level gating is needed, and use `inspect_params: true` in `common.rs` when only some fields of a method are experimental.
-
-### Development Workflow
-
-- Update docs/examples when API behavior changes (at minimum `app-server/README.md`).
-- Regenerate schema fixtures when API shapes change:
-  `just write-app-server-schema`
-  (and `just write-app-server-schema --experimental` when experimental API fixtures are affected).
-- Validate with `cargo test -p codex-app-server-protocol`.

-## Quickstart
-
-### Installing and running Codex CLI
-
-Install globally with your preferred package manager:
-
-```shell
-# Install using npm
-npm install -g @openai/codex
-```
-
-```shell
-# Install using Homebrew
-brew install --cask codex
-```
-
-Then simply run `codex` to get started.
-
 <details>
-<summary>You can also go to the <a href="https://github.com/openai/codex/releases/latest">latest GitHub Release</a> and download the appropriate binary for your platform.</summary>
+<summary><strong>Table&nbsp;of&nbsp;Contents</strong></summary>
 
-Each GitHub Release contains many executables, but in practice, you likely want one of these:
-
-- macOS
-  - Apple Silicon/arm64: `codex-aarch64-apple-darwin.tar.gz`
-  - x86_64 (older Mac hardware): `codex-x86_64-apple-darwin.tar.gz`
-- Linux
-  - x86_64: `codex-x86_64-unknown-linux-musl.tar.gz`
-  - arm64: `codex-aarch64-unknown-linux-musl.tar.gz`
-
-Each archive contains a single entry with the platform baked into the name (e.g., `codex-x86_64-unknown-linux-musl`), so you likely want to rename it to `codex` after extracting it.

-### Using Codex with your ChatGPT plan
+---
 
-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).
+## Experimental Technology Disclaimer
 
-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).
+Codex CLI is an experimental project under active development. It is not yet stable, may contain bugs, incomplete features, or undergo breaking changes. We’re building it in the open with the community and welcome:

-This repository is licensed under the [Apache-2.0 License](LICENSE).
+## Quickstart
+
+Install globally:
+
+```shell
+npm install -g @openai/codex
+```
+
+Next, set your OpenAI API key as an environment variable:
+
+```shell
+export OPENAI_API_KEY="your-api-key-here"
+```
+
+> **Note:** This command sets the key only for your current terminal session. To make it permanent, add the `export` line to your shell's configuration file (e.g., `~/.zshrc`).
+>
+> **Tip:** You can also place your API key into a `.env` file at the root of your project:
+>
+> ```env
+> OPENAI_API_KEY=your-api-key-here
+> ```
+>
+> The CLI will automatically load variables from `.env` (via `dotenv/config`).
+
+Run interactively:
+
+```shell
+codex
+```
+
+Or, run with a prompt as input (and optionally in `Full Auto` mode):
+
+```shell
+codex "explain this codebase to me"
+```
+
+```shell
+codex --approval-mode 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.
+
+---
+
+## Why Codex?
+
+Codex CLI is built for developers who already **live in the terminal** and want
+ChatGPT‑level reasoning **plus** the power to actually run code, manipulate
+files, and iterate – all under version control. In short, it’s _chat‑driven
+development_ that understands and executes your repo.
+
+- **Zero setup** — bring your OpenAI API key and it just works!
+- **Full auto-approval, while safe + secure** by running network-disabled and directory-sandboxed
+- **Multimodal** — pass in screenshots or diagrams to implement features ✨
+
+And it's **fully open-source** so you can see and contribute to how it develops!
+
+---
+
+## Security Model & Permissions
+
+Codex lets you decide _how much autonomy_ the agent receives and auto-approval policy via the
+`--approval-mode` flag (or the interactive onboarding prompt):
+
+| Mode                      | What the agent may do without asking                                                               | Still requires approval                                                                         |
+| ------------------------- | -------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- |
+| **Suggest** <br>(default) | • Read any file in the repo                                                                        | • **All** file writes/patches <br>• **Any** arbitrary shell commands (aside from reading files) |
+| **Auto Edit**             | • Read **and** apply‑patch writes to files                                                         | • **All** shell commands                                                                        |
+| **Full Auto**             | • Read/write files <br>• Execute shell commands (network disabled, writes limited to your workdir) | –                                                                                               |
+
+In **Full Auto** every command is run **network‑disabled** and confined to the
+current working directory (plus temporary files) for defense‑in‑depth. Codex
+will also show a warning/confirmation if you start in **auto‑edit** or
+**full‑auto** while the directory is _not_ tracked by Git, so you always have a
+safety net.
+
+Coming soon: you’ll be able to whitelist specific commands to auto‑execute with
+the network enabled, once we’re confident in additional safeguards.
+
+### Platform sandboxing details
+
+The hardening mechanism Codex uses depends on your OS:
+
+- **macOS 12+** – commands are wrapped with **Apple Seatbelt** (`sandbox-exec`).
+
+  - Everything is placed in a read‑only jail except for a small set of
+    writable roots (`$PWD`, `$TMPDIR`, `~/.codex`, etc.).
+  - Outbound network is _fully blocked_ by default – even if a child process
+    tries to `curl` somewhere it will fail.
+
+- **Linux** – there is no sandboxing by default.
+  We recommend using Docker for sandboxing, where Codex launches itself inside a **minimal
+  container image** and mounts your repo _read/write_ at the same path. A
+  custom `iptables`/`ipset` firewall script denies all egress except the
+  OpenAI API. This gives you deterministic, reproducible runs without needing
+  root on the host. You can use the [`run_in_container.sh`](./codex-cli/scripts/run_in_container.sh) script to set up the sandbox.

+| `codex "…"`                          | Initial prompt for interactive REPL | `codex "fix lint errors"`            |
+| `codex -q "…"`                       | Non‑interactive "quiet mode"        | `codex -q --json "explain utils.ts"` |
+| `codex completion <bash\|zsh\|fish>` | Print shell completion script       | `codex completion bash`              |
+
+Key flags: `--model/-m`, `--approval-mode/-a`, `--quiet/-q`, and `--notify`.
+
+---
+
+## Memory & Project Docs
+
+Codex merges Markdown instructions in this order:
+
+1. `~/.codex/instructions.md` – personal global guidance
+2. `codex.md` at repo root – shared project notes
+3. `codex.md` in cwd – sub‑package specifics
+
+Disable with `--no-project-doc` or `CODEX_DISABLE_PROJECT_DOC=1`.
+
+---
+
+## 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 -a auto-edit --quiet "update CHANGELOG for next release"
+```
+
+Set `CODEX_QUIET_MODE=1` to silence interactive UI noise.
+
+## Tracing / Verbose Logging
+
+Setting the environment variable `DEBUG=true` prints full API request and response details:
+
+```shell
+DEBUG=true 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) Organization Limitation
+
+> **Note:** Codex CLI does **not** currently 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, you may 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.
+```
+
+**Why?**
+
+- Codex CLI relies on the Responses API with `store:true` to enable internal reasoning steps.
+- As noted in the [docs](https://platform.openai.com/docs/guides/your-data#responses-api), the Responses API requires a 30-day retention period by default, or when the store parameter is set to true.
+- ZDR organizations cannot use `store:true`, so requests will fail.
+
+**What can I do?**
+
+- If you are part of a ZDR organization, Codex CLI will not work until support is added.
+- We are tracking this limitation and will update the documentation if support becomes available.
+
+---
+
+## Funding Opportunity
+
+We’re excited to launch a **$1 million initiative** supporting open source projects that use Codex CLI and other OpenAI models.
+
+- Grants are awarded in **$25,000** API credit increments.
+- Applications are reviewed **on a rolling basis**.

+
+## Contributing
+
+This project is under active development and the code will likely change pretty significantly. We'll update this message once that's complete!
+
+More broadly we welcome contributions – whether you are opening your very first pull request or you’re a seasoned maintainer. At the same time we care about reliability and long‑term maintainability, so the bar for merging code is intentionally **high**. The guidelines below spell out what “high‑quality” means in practice and should make the whole process transparent and friendly.
+
+### 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.
+- Use `npm run test:watch` during development for super‑fast feedback.
+- We use **Vitest** for unit tests, **ESLint** + **Prettier** for style, and **TypeScript** for type‑checking.
+- Before pushing, run the full test/type/lint suite:
+
+### Git Hooks with Husky
+
+This project uses [Husky](https://typicode.github.io/husky/) to enforce code quality checks:
+
+- **Pre-commit hook**: Automatically runs lint-staged to format and lint files before committing
+- **Pre-push hook**: Runs tests and type checking before pushing to the remote
+
+These hooks help maintain code quality and prevent pushing code with failing tests. For more details, see [HUSKY.md](./codex-cli/HUSKY.md).
+
+```bash
+npm test && npm run lint && npm run typecheck
+```
+
+- If you have **not** yet signed the Contributor License Agreement (CLA), add a PR comment containing the exact text
+
+  ```text
+  I have read the CLA Document and I hereby sign the CLA
+  ```
+
+  The CLA‑Assistant bot will turn the PR status green once all authors have signed.
+
+```bash
+# Watch mode (tests rerun on change)
+npm run test:watch
+
+# Type‑check without emitting files
+npm run typecheck
+
+# Automatically fix lint + prettier issues
+npm run lint:fix
+npm run format:fix
+```
+
+#### Nix Flake Development
+
+Prerequisite: Nix >= 2.4 with flakes enabled (`experimental-features = nix-command flakes` in `~/.config/nix/nix.conf`).
+
+Enter a Nix development shell:
+
+```bash
+nix develop
+```
+
+This shell includes Node.js, installs dependencies, builds the CLI, and provides a `codex` command alias.
+
+Build and run the CLI directly:
+
+```bash
+nix build
+./result/bin/codex --help
+```
+
+Run the CLI via the flake app:
+
+```bash
+nix run .#codex
+```
+
+### 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 (`npm test && npm run lint && npm run typecheck`). 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. We may ask for changes – please do not take this personally. We value the work, we just also value consistency and long‑term maintainability.
+3. 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`                                          |
+| GitHub UI only    | Edit the commit message in the PR → add<br>`Signed-off-by: Your Name <email@example.com>` |
+
+The **DCO check** blocks merges until every commit in the PR carries the footer (with squash this is just the one).
+
+### Releasing `codex`
+
+To publish a new version of the CLI, run the release scripts defined in `codex-cli/package.json`:
+
+1. Open the `codex-cli` directory
+2. Make sure you're on a branch like `git checkout -b bump-version`
+3. Bump the version and `CLI_VERSION` to current datetime: `npm run release:version`
+4. Commit the version bump (with DCO sign-off):
+   ```bash
+   git add codex-cli/src/utils/session.ts codex-cli/package.json
+   git commit -s -m "chore(release): codex-cli v$(node -p \"require('./codex-cli/package.json').version\")"
+   ```
+5. Copy README, build, and publish to npm: `npm run release`
+6. Push to branch: `git push origin HEAD`

+# Husky Git Hooks
+
+This project uses [Husky](https://typicode.github.io/husky/) to enforce code quality checks before commits and pushes.
+
+## What's Included
+
+- **Pre-commit Hook**: Runs lint-staged to check files that are about to be committed.
+
+  - Lints and formats TypeScript/TSX files using ESLint and Prettier
+  - Formats JSON, MD, and YML files using Prettier
+
+- **Pre-push Hook**: Runs tests and type checking before pushing to the remote repository.
+  - Executes `npm test` to run all tests
+  - Executes `npm run typecheck` to check TypeScript types
+
+## Benefits
+
+- Ensures consistent code style across the project
+- Prevents pushing code with failing tests or type errors
+- Reduces the need for style-related code review comments
+- Improves overall code quality
+
+## For Contributors
+
+You don't need to do anything special to use these hooks. They will automatically run when you commit or push code.
+
+If you need to bypass the hooks in exceptional cases:
+
+```bash
+# Skip pre-commit hooks
+git commit -m "Your message" --no-verify
+
+# Skip pre-push hooks
+git push --no-verify
+```
+
+Note: Please use these bypass options sparingly and only when absolutely necessary.
+
+## Troubleshooting
+
+If you encounter any issues with the hooks:
+
+1. Make sure you have the latest dependencies installed: `npm install`
+2. Ensure the hook scripts are executable (Unix systems): `chmod +x .husky/pre-commit .husky/pre-push`
+3. Check if there are any ESLint or Prettier configuration issues in your code

-## Experimental technology disclaimer
-
-Codex CLI is an experimental project under active development. It is not yet stable, may contain bugs, incomplete features, or undergo breaking changes. We're building it in the open with the community and welcome:
-
-- Bug reports
-- Feature requests
-- Pull requests
-- Good vibes
-
-Help us improve by filing issues or submitting PRs (see the section below for how to contribute)!
-
-## Quickstart
-
-Install globally:
-
-```shell
-npm install -g @openai/codex
-```
-
-Next, set your OpenAI API key as an environment variable:
-
-```shell
-export OPENAI_API_KEY="your-api-key-here"
-```
-
-> **Note:** This command sets the key only for your current terminal session. You can add the `export` line to your shell's configuration file (e.g., `~/.zshrc`) but we recommend setting for the session. **Tip:** You can also place your API key into a `.env` file at the root of your project:
->
-> ```env
-> OPENAI_API_KEY=your-api-key-here
-> ```
->
-> The CLI will automatically load variables from `.env` (via `dotenv/config`).
-
-<details>
-<summary><strong>Use <code>--provider</code> to use other models</strong></summary>
-
-> Codex also allows you to use other providers that support the OpenAI Chat Completions API. You can set the provider in the config file or use the `--provider` flag. The possible options for `--provider` are:
->
-> - openai (default)
-> - openrouter
-> - azure
-> - gemini
-> - ollama
-> - mistral
-> - deepseek
-> - xai
-> - groq
-> - arceeai
-> - any other provider that is compatible with the OpenAI API
->
-> If you use a provider other than OpenAI, you will need to set the API key for the provider in the config file or in the environment variable as:
->
-> ```shell
-> export <provider>_API_KEY="your-api-key-here"
-> ```
->
-> If you use a provider not listed above, you must also set the base URL for the provider:
->
-> ```shell
-> export <provider>_BASE_URL="https://your-provider-api-base-url"
-> ```
-
-</details>
-<br />
-
-Run interactively:
-
-```shell
-codex
-```
-
-Or, run with a prompt as input (and optionally in `Full Auto` mode):
-
-```shell
-codex "explain this codebase to me"
-```
-
-```shell
-codex --approval-mode 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.
-
----
-
-## Why Codex?
-
-Codex CLI is built for developers who already **live in the terminal** and want
-ChatGPT-level reasoning **plus** the power to actually run code, manipulate
-files, and iterate - all under version control. In short, it's _chat-driven
-development_ that understands and executes your repo.
-
-- **Zero setup** - bring your OpenAI API key and it just works!
-- **Full auto-approval, while safe + secure** by running network-disabled and directory-sandboxed
-- **Multimodal** - pass in screenshots or diagrams to implement features ✨
-
-And it's **fully open-source** so you can see and contribute to how it develops!
-
----
-
-## Security model & permissions
-
-Codex lets you decide _how much autonomy_ the agent receives and auto-approval policy via the
-`--approval-mode` flag (or the interactive onboarding prompt):
-
-| Mode                      | What the agent may do without asking                                                                | Still requires approval                                                                         |
-| ------------------------- | --------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- |
-| **Suggest** <br>(default) | <li>Read any file in the repo                                                                       | <li>**All** file writes/patches<li> **Any** arbitrary shell commands (aside from reading files) |
-| **Auto Edit**             | <li>Read **and** apply-patch writes to files                                                        | <li>**All** shell commands                                                                      |
-| **Full Auto**             | <li>Read/write files <li> Execute shell commands (network disabled, writes limited to your workdir) | -                                                                                               |
-
-In **Full Auto** every command is run **network-disabled** and confined to the
-current working directory (plus temporary files) for defense-in-depth. Codex
-will also show a warning/confirmation if you start in **auto-edit** or
-**full-auto** while the directory is _not_ tracked by Git, so you always have a
-safety net.
-
-Coming soon: you'll be able to whitelist specific commands to auto-execute with
-the network enabled, once we're confident in additional safeguards.
-
-### Platform sandboxing details
-
-The hardening mechanism Codex uses depends on your OS:
-
-- **macOS 12+** - commands are wrapped with **Apple Seatbelt** (`sandbox-exec`).
-
-  - Everything is placed in a read-only jail except for a small set of
-    writable roots (`$PWD`, `$TMPDIR`, `~/.codex`, etc.).
-  - Outbound network is _fully blocked_ by default - even if a child process
-    tries to `curl` somewhere it will fail.
-
-- **Linux** - there is no sandboxing by default.
-  We recommend using Docker for sandboxing, where Codex launches itself inside a **minimal
-  container image** and mounts your repo _read/write_ at the same path. A
-  custom `iptables`/`ipset` firewall script denies all egress except the
-  OpenAI API. This gives you deterministic, reproducible runs without needing
-  root on the host. You can use the [`run_in_container.sh`](../codex-cli/scripts/run_in_container.sh) script to set up the sandbox.

-| ------------------------------------ | ----------------------------------- | ------------------------------------ |
-| `codex`                              | Interactive REPL                    | `codex`                              |
-| `codex "..."`                        | Initial prompt for interactive REPL | `codex "fix lint errors"`            |
-| `codex -q "..."`                     | Non-interactive "quiet mode"        | `codex -q --json "explain utils.ts"` |
-| `codex completion <bash\|zsh\|fish>` | Print shell completion script       | `codex completion bash`              |
-
-Key flags: `--model/-m`, `--approval-mode/-a`, `--quiet/-q`, and `--notify`.
-
----
-
-## 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
-
-Disable loading of these files with `--no-project-doc` or the environment variable `CODEX_DISABLE_PROJECT_DOC=1`.
-
----
-
-## 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 -a auto-edit --quiet "update CHANGELOG for next release"
-```
-
-Set `CODEX_QUIET_MODE=1` to silence interactive UI noise.
-
-## Tracing / verbose logging
-
-Setting the environment variable `DEBUG=true` prints full API request and response details:
-
-```shell
-DEBUG=true codex
-```

-| 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.                                          |

-### Custom instructions
-
-You can create a `~/.codex/AGENTS.md` file to define custom guidance for the agent:
-
-```markdown
-- Always respond with emojis
-- Only use git commands when explicitly requested
-```
-
-### Environment variables setup
-
-For each AI provider, you need to set the corresponding API key in your environment variables. For example:
-
-```bash
-# OpenAI
-export OPENAI_API_KEY="your-api-key-here"
-
-# Azure OpenAI
-export AZURE_OPENAI_API_KEY="your-azure-api-key-here"
-export AZURE_OPENAI_API_VERSION="2025-04-01-preview" (Optional)
-
-# OpenRouter
-export OPENROUTER_API_KEY="your-openrouter-key-here"
-
-# Similarly for other providers
-```

-## 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 is regularly tested on macOS and Linux with Node 20+, and also supports Node 16.
-
-</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.
-```
-
-You may need to upgrade to a more recent version with: `npm i -g @openai/codex@latest`
-
----
-
-## 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. We'll update this message once that's complete!
-
-More broadly we welcome contributions - whether you are opening your very first pull request or you're a seasoned maintainer. At the same time we care about reliability and long-term maintainability, so the bar for merging code is intentionally **high**. The guidelines below spell out what "high-quality" means in practice and should make the whole process transparent and friendly.
-
-### 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.
-- Use `pnpm test:watch` during development for super-fast feedback.
-- We use **Vitest** for unit tests, **ESLint** + **Prettier** for style, and **TypeScript** for type-checking.
-- Before pushing, run the full test/type/lint suite:
-
-### Git hooks with Husky
-
-This project uses [Husky](https://typicode.github.io/husky/) to enforce code quality checks:
-
-- **Pre-commit hook**: Automatically runs lint-staged to format and lint files before committing
-- **Pre-push hook**: Runs tests and type checking before pushing to the remote
-
-These hooks help maintain code quality and prevent pushing code with failing tests. For more details, see [HUSKY.md](./HUSKY.md).
-
-```bash
-pnpm test && pnpm run lint && pnpm run typecheck
-```
-
-- If you have **not** yet signed the Contributor License Agreement (CLA), add a PR comment containing the exact text
-
-  ```text
-  I have read the CLA Document and I hereby sign the CLA
-  ```
-
-  The CLA-Assistant bot will turn the PR status green once all authors have signed.
-
-```bash
-# Watch mode (tests rerun on change)
-pnpm test:watch
-
-# Type-check without emitting files
-pnpm typecheck
-
-# Automatically fix lint + prettier issues
-pnpm lint:fix
-pnpm format:fix
-```
-
-### Debugging
-
-To debug the CLI with a visual debugger, do the following in the `codex-cli` folder:
-
-- Run `pnpm run build` to build the CLI, which will generate `cli.js.map` alongside `cli.js` in the `dist` folder.
-- Run the CLI with `node --inspect-brk ./dist/cli.js` The program then waits until a debugger is attached before proceeding. Options:
-  - In VS Code, choose **Debug: Attach to Node Process** from the command palette and choose the option in the dropdown with debug port `9229` (likely the first option)
-  - Go to <chrome://inspect> in Chrome and find **localhost:9229** and click **trace**
-
-### 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 (`npm test && npm run lint && npm run typecheck`). 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. We may ask for changes - please do not take this personally. We value the work, we just also value consistency and long-term maintainability.
-3. 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`
-
-To publish a new version of the CLI you first need to stage the npm package. A
-helper script in `codex-cli/scripts/` does all the heavy lifting. Inside the
-`codex-cli` folder run:
-
-```bash
-# Classic, JS implementation that includes small, native binaries for Linux sandboxing.
-pnpm stage-release
-
-# Optionally specify the temp directory to reuse between runs.
-RELEASE_DIR=$(mktemp -d)
-pnpm stage-release --tmp "$RELEASE_DIR"
-
-# "Fat" package that additionally bundles the native Rust CLI binaries for
-# Linux. End-users can then opt-in at runtime by setting CODEX_RUST=1.
-pnpm stage-release --native
-```
-
-Go to the folder where the release is staged and verify that it works as intended. If so, run the following from the temp folder:
-
-```
-cd "$RELEASE_DIR"
-npm publish
-```
-
-### Alternative build options
-
-#### Nix flake development
-
-Prerequisite: Nix >= 2.4 with flakes enabled (`experimental-features = nix-command flakes` in `~/.config/nix/nix.conf`).
-
-Enter a Nix development shell:
-
-```bash
-# Use either one of the commands according to which implementation you want to work with
-nix develop .#codex-cli # For entering codex-cli specific shell
-nix develop .#codex-rs # For entering codex-rs specific shell
-```
-
-This shell includes Node.js, installs dependencies, builds the CLI, and provides a `codex` command alias.
-
-Build and run the CLI directly:
-
-```bash
-# Use either one of the commands according to which implementation you want to work with
-nix build .#codex-cli # For building codex-cli
-nix build .#codex-rs # For building codex-rs
-./result/bin/codex --help
-```
-
-Run the CLI via the flake app:
-
-```bash
-# Use either one of the commands according to which implementation you want to work with
-nix run .#codex-cli # For running codex-cli
-nix run .#codex-rs # For running codex-rs
-```
-
-Use direnv with flakes
-
-If you have direnv installed, you can use the following `.envrc` to automatically enter the Nix shell when you `cd` into the project directory:
-
-```bash
-cd codex-rs
-echo "use flake ../flake.nix#codex-cli" >> .envrc && direnv allow
-cd codex-cli
-echo "use flake ../flake.nix#codex-rs" >> .envrc && direnv allow
-```

+# Quick start examples
+
+This directory bundles some self‑contained examples using the Codex CLI. If you have never used the Codex CLI before, and want to see it complete a sample task, start with running **camerascii**. You'll see your webcam feed turned into animated ASCII art in a few minutes.
+
+If you want to get started using the Codex CLI directly, skip this and refer to the prompting guide.
+
+## Structure
+
+Each example contains the following:
+```
+example‑name/
+├── run.sh           # helper script that launches a new Codex session for the task
+├── task.yaml        # task spec containing a prompt passed to Codex
+├── template/        # (optional) starter files copied into each run
+└── runs/            # work directories created by run.sh
+```
+
+**run.sh**: a convenience wrapper that does three things:
+- Creates `runs/run_N`, where *N* is the number of a run.
+- Copies the contents of `template/` into that folder (if present).
+- Launches the Codex CLI with the description from `task.yaml`.
+
+**template/**: any existing files or markdown instructions you would like Codex to see before it starts working.
+
+**runs/**: the directories produced by `run.sh`.
+
+## Running an example
+
+1. **Run the helper script**:
+```
+cd camerascii
+./run.sh
+```
+2. **Interact with the Codex CLI**: the CLI will open with the prompt: “*Take a look at the screenshot details and implement a webpage that uses a webcam to style the video feed accordingly…*” Confirm the commands Codex CLI requests to generate `index.html`.
+
+3. **Check its work**: when Codex is done, open ``runs/run_1/index.html`` in a browser.  Your webcam feed should now be rendered as a cascade of ASCII glyphs. If the outcome isn't what you expect, try running it again, or adjust the task prompt.
+
+
+## Other examples
+Besides **camerascii**, you can experiment with:
+
+- **build‑codex‑demo**: recreate the original 2021 Codex YouTube demo.
+- **impossible‑pong**: where Codex creates more difficult levels.
+- **prompt‑analyzer**: make a data science app for clustering [prompts](https://github.com/f/awesome-chatgpt-prompts).

+description: |
+  I want you to reimplement the original OpenAI Codex demo.
+
+  Functionality:
+  - User types a prompt and hits enter to send
+  - The prompt is added to the conversation history
+  - The backend calls the OpenAI API with stream: true
+  - Tokens are streamed back and appended to the code viewer
+  - Syntax highlighting updates in real time
+  - When a full HTML file is received, it is rendered in a sandboxed iframe
+  - The iframe replaces the previous preview with the new HTML after the stream is complete (i.e. keep the old preview until a new stream is complete)
+  - Append each assistant and user message to preserve context across turns
+  - Errors are displayed to user gracefully
+  - Ensure there is a fixed layout is responsive and faithful to the screenshot design
+  - Be sure to parse the output from OpenAI call to strip the ```html tags code is returned within
+  - Use the system prompt shared in the API call below to ensure the AI only returns HTML
+
+  Support a simple local backend that can:
+  - Read local env for OPENAI_API_KEY
+  - Expose an endpoint that streams completions from OpenAI
+  - Backend should be a simple node.js app
+  - App should be easy to run locally for development and testing
+  - Minimal setup preferred — keep dependencies light unless justified
+
+  Description of layout and design:
+  - Two stacked panels, vertically aligned:
+    - Top Panel: Main interactive area with two main parts
+    - Left Side: Visual output canvas. Mostly blank space with a small image preview in the upper-left
+  - Right Side: Code display area
+    - Light background with code shown in a monospace font
+    - Comments in green; code aligns vertically like an IDE/snippet view
+  - Bottom Panel: Prompt/command bar
+    - A single-line text box with a placeholder prompt
+    - A green arrow (submit button) on the right side
+  - Scrolling should only be supported in the code editor and output canvas
+
+  Visual style
+  - Minimalist UI, light and clean
+  - Neutral white/gray background
+  - Subtle shadow or border around both panels, giving them card-like elevation
+  - Code section is color-coded, likely for syntax highlighting
+  - Interactive feel with the text input styled like a chat/message interface
+
+  Here's the latest OpenAI API and prompt to use:
+  ```
+  import OpenAI from "openai";
+
+  const openai = new OpenAI({
+    apiKey: process.env.OPENAI_API_KEY,
+  });
+
+  const response = await openai.responses.create({
+    model: "gpt-4.1",
+    input: [
+      {
+        "role": "system",
+        "content": [
+          {
+            "type": "input_text",
+            "text": "You are a coding agent that specializes in frontend code. Whenever you are prompted, return only the full HTML file."
+          }
+        ]
+      }
+    ],
+    text: {
+      "format": {
+        "type": "text"
+      }
+    },
+    reasoning: {},
+    tools: [],
+    temperature: 1,
+    top_p: 1
+  });
+
+  console.log(response.output_text);
+  ```
+  Additional things to note:
+  - Strip any html and tags from the OpenAI response before rendering
+  - Assume the OpenAI API model response always wraps HTML in markdown-style triple backticks like ```html <code> ```
+  - The display code window should have syntax highlighting and line numbers.
+  - Make sure to only display the code, not the backticks or ```html that wrap the code from the model.
+  - Do not inject raw markdown; only parse and insert pure HTML into the iframe
+  - Only the code viewer and output panel should scroll
+  - Keep the previous preview visible until the full new HTML has streamed in
+
+  Add a README.md with what you've implemented and how to run it.

+### Screenshot Description
+
+The image is a full–page screenshot of a single post on the social‑media site X (formerly Twitter).
+
+1. **Header row**
+   * At the very top‑left is a small circular avatar.  The photo shows the side profile of a person whose face is softly lit in bluish‑purple tones; only the head and part of the neck are visible.
+   * In the far upper‑right corner sit two standard X / Twitter interface icons: a circle containing a diagonal line (the “Mute / Block” indicator) and a three‑dot overflow menu.
+
+2. **Tweet body text**
+   * Below the header, in regular type, the author writes:
+
+     “Okay, OpenAI’s o3 is insane. Spent an hour messing with it and built an image‑to‑ASCII art converter, the exact tool I’ve always wanted. And it works so well”
+
+3. **Embedded media**
+   * The majority of the screenshot is occupied by an embedded 12‑second video of the converter UI.  The video window has rounded corners and a dark theme.
+   * **Left panel (tool controls)** – a slim vertical sidebar with the following labeled sections and blue–accented UI controls:
+     * Theme selector (“Dark” is chosen).
+     * A small checkbox labeled “Ignore White”.
+     * **Upload Image** button area that shows the chosen file name.
+     * **Image Processing** sliders:
+       * “ASCII Width” (value ≈ 143)
+       * “Brightness” (‑65)
+       * “Contrast” (58)
+       * “Blur (px)” (0.5)
+       * A square checkbox for “Invert Colors”.
+     * **Dithering** subsection with a checkbox (“Enable Dithering”) and a dropdown for the algorithm (value: “Noise”).
+     * **Character Set** dropdown (value: “Detailed (Default)”).
+     * **Display** slider labeled “Zoom (%)” (value ≈ 170) and a “Reset” button.
+
+   * **Main preview area (right side)** – a dark gray canvas that renders the selected image as white ASCII characters.  The preview clearly depicts a stylized **palm tree**: a skinny trunk rises from the bottom centre, and a crown of splayed fronds fills the upper right quadrant.
+   * A small black badge showing **“0:12”** overlays the bottom‑left corner of the media frame, indicating the video’s duration.
+   * In the top‑right area of the media window are two pill‑shaped buttons: a heart‑shaped “Save” button and a cog‑shaped “Settings” button.
+
+Overall, the screenshot shows the user excitedly announcing the success of their custom “Image to ASCII” converter created with OpenAI’s “o3”, accompanied by a short video demonstration of the tool converting a palm‑tree photo into ASCII art.

+name: "prompt-analyzer"
+description: |
+  I have some existing work here (embedding prompts, clustering them, generating
+  summaries with GPT). I want to make it more interactive and reusable.
+
+  Objective: create an interactive cluster explorer
+     - Build a lightweight streamlit app UI
+     - Allow users to upload a CSV of prompts
+     - Display clustered prompts with auto-generated cluster names and summaries
+     - Click "cluster" and see progress stream in a small window (primarily for aesthetic reasons)
+     - Let users browse examples by cluster, view outliers, and inspect individual prompts
+     - See generated analysis rendered in the app, along with the plots displayed nicely
+     - Support selecting clustering algorithms (e.g. DBSCAN, KMeans, etc) and "recluster"
+     - Include token count + histogram of prompt lengths
+     - Add interactive filters in UI (e.g. filter by token length, keyword, or cluster)
+
+  When you're done, update the README.md with a changelog and instructions for how to run the app.

+# Prompt‑Clustering Utility
+
+This repository contains a small utility (`cluster_prompts.py`) that embeds a
+list of prompts with the OpenAI Embedding API, discovers natural groupings with
+unsupervised clustering, lets ChatGPT name & describe each cluster and finally
+produces a concise Markdown report plus a couple of diagnostic plots.
+
+The default input file (`prompts.csv`) ships with the repo so you can try the
+script immediately, but you can of course point it at your own file.
+
+---
+
+## 1. Setup
+
+1. Install the Python dependencies (preferably inside a virtual env):
+
+```bash
+pip install pandas numpy scikit-learn matplotlib openai
+```
+
+2. Export your OpenAI API key (**required**):
+
+```bash
+export OPENAI_API_KEY="sk‑..."
+```
+
+---
+
+## 2. Basic usage
+
+```bash
+# Minimal command – runs on prompts.csv and writes analysis.md + plots/
+python cluster_prompts.py
+```
+
+This will
+
+* create embeddings with the `text-embedding-3-small` model, 
+* pick a suitable number *k* via silhouette score (K‑Means),
+* ask `gpt‑4o‑mini` to label & describe each cluster,
+* store the results in `analysis.md`,
+* and save two plots to `plots/` (`cluster_sizes.png` and `tsne.png`).
+
+The script prints a short success message once done.
+
+---
+
+## 3. Command‑line options
+
+| flag | default | description |
+|------|---------|-------------|
+| `--csv` | `prompts.csv` | path to the input CSV (must contain a `prompt` column; an `act` column is used as context if present) |
+| `--cache` | _(none)_ | embed­ding cache path (JSON). Speeds up repeated runs – new texts are appended automatically. |
+| `--cluster-method` | `kmeans` | `kmeans` (with automatic *k*) or `dbscan` |
+| `--k-max` | `10` | upper bound for *k* when `kmeans` is selected |
+| `--dbscan-min-samples` | `3` | min samples parameter for DBSCAN |
+| `--embedding-model` | `text-embedding-3-small` | any OpenAI embedding model |
+| `--chat-model` | `gpt-4o-mini` | chat model used to generate cluster names / descriptions |
+| `--output-md` | `analysis.md` | where to write the Markdown report |
+| `--plots-dir` | `plots` | directory for generated PNGs |
+
+Example with customised options:
+
+```bash
+python cluster_prompts.py \
+  --csv my_prompts.csv \
+  --cache .cache/embeddings.json \
+  --cluster-method dbscan \
+  --embedding-model text-embedding-3-large \
+  --chat-model gpt-4o \
+  --output-md my_analysis.md \
+  --plots-dir my_plots
+```
+
+---
+
+## 4. Interpreting the output
+
+### analysis.md

+
+## 5. Troubleshooting
+
+* **Rate‑limits / quota errors** – lower the number of prompts per run or switch
+  to a larger quota account.
+* **Authentication errors** – make sure `OPENAI_API_KEY` is exported in the
+  shell where you run the script.
+* **Inadequate clusters** – try the other clustering method, adjust `--k-max`
+  or tune DBSCAN parameters (`eps` range is inferred, `min_samples` exposed via
+  CLI).

+"""End‑to‑end pipeline for analysing a collection of text prompts.
+
+The script performs the following steps:
+
+1.  Read a CSV file that must contain a column named ``prompt``. If an
+    ``act`` column is present it is used purely for reporting purposes.
+2.  Create embeddings via the OpenAI API (``text-embedding-3-small`` by
+    default).  The user can optionally provide a JSON cache path so the
+    expensive embedding step is only executed for new / unseen texts.
+3.  Cluster the resulting vectors either with K‑Means (automatically picking
+    *k* through the silhouette score) or with DBSCAN.  Outliers are flagged
+    as cluster ``-1`` when DBSCAN is selected.
+4.  Ask a Chat Completion model (``gpt-4o-mini`` by default) to come up with a
+    short name and description for every cluster.
+5.  Write a human‑readable Markdown report (default: ``analysis.md``).
+6.  Generate a couple of diagnostic plots (cluster sizes and a t‑SNE scatter
+    plot) and store them in ``plots/``.
+
+The script is intentionally opinionated yet configurable via a handful of CLI
+options – run ``python cluster_prompts.py --help`` for details.
