-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 `[]`.

 - 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

-- When making a change that adds or changes an API, ensure that the documentation in the `docs/` folder is up to date if applicable.
 
 Run `just fmt` (in `codex-rs` directory) automatically after making Rust code changes; do not ask for approval to run it. Before finalizing a 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. 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`.
-   When running interactively, ask the user before running `just fix` to finalize. `just fmt` does not require approval. project-specific or individual tests can be run without asking the user, but do ask the user before running the complete test suite.

 - 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).

 - 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.

-### Integration tests (core)
-
-- Prefer the utilities in `core_test_support::responses` when writing end-to-end Codex tests.
-

-- 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(...)`.

-- Typical pattern:
-
-  ```rust
-  let mock = responses::mount_sse_once(&server, responses::sse(vec![

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

-You can also install via Homebrew (`brew install --cask codex`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/openai/codex/releases).

-## Documentation quickstart

-- First run with Codex? Follow the walkthrough in [`docs/getting-started.md`](../docs/getting-started.md) for prompts, keyboard shortcuts, and session management.
-- Already shipping with Codex and want deeper control? Jump to [`docs/advanced.md`](../docs/advanced.md) and the configuration reference at [`docs/config.md`](../docs/config.md).

-The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.

+### Use `@` for file search
+
+Typing `@` triggers a fuzzy-filename search over the workspace root. Use up/down to select among the results and Tab or Enter to replace the `@` with the selected path. You can use Esc to cancel the search.
+
+### Esc–Esc to edit a previous message
+
+When the chat composer is empty, press Esc to prime “backtrack” mode. Press Esc again to open a transcript preview highlighting the last user message; press Esc repeatedly to step to older user messages. Press Enter to confirm and Codex will fork the conversation from that point, trim the visible transcript accordingly, and pre‑fill the composer with the selected user message so you can edit and resubmit it.
+
+In the transcript preview, the footer shows an `Esc edit prev` hint while editing is active.
+
+### `--cd`/`-C` flag
+
+Sometimes it is not convenient to `cd` to the directory you want Codex to use as the "working root" before running Codex. Fortunately, `codex` supports a `--cd` option so you can specify whatever folder you want. You can confirm that Codex is honoring `--cd` by double-checking the **workdir** it reports in the TUI at the start of a new session.
+
+### Shell completions
+
+Generate shell completion scripts via:
+
+```shell
+codex completion bash
+codex completion zsh
+codex completion fish
+```
+
 ### Experimenting with the Codex Sandbox
 
 To test to see what happens when a command is run under the sandbox provided by Codex, we provide the following subcommands in Codex CLI:
 
 ```
 # macOS
-codex sandbox macos [--full-auto] [COMMAND]...
+codex debug seatbelt [--full-auto] [COMMAND]...
 
 # Linux
-codex sandbox linux [--full-auto] [COMMAND]...
-
-# Legacy aliases
-codex debug seatbelt [--full-auto] [COMMAND]...
 codex debug landlock [--full-auto] [COMMAND]...
 ```

-# codex-app-server
-
-`codex app-server` is the harness Codex uses to power rich interfaces such as the [Codex VS Code extension](https://marketplace.visualstudio.com/items?itemName=openai.chatgpt). The message schema is currently unstable, but those who wish to build experimental UIs on top of Codex may find it valuable.
-
-## Protocol
-
-Similar to [MCP](https://modelcontextprotocol.io/), `codex app-server` supports bidirectional communication, streaming JSONL over stdio. The protocol is JSON-RPC 2.0, though the `"jsonrpc":"2.0"` header is omitted.
-
-## Message Schema
-
-Currently, you can dump a TypeScript version of the schema using `codex generate-ts`. It is specific to the version of Codex you used to run `generate-ts`, so the two are guaranteed to be compatible.
-
-```
-codex generate-ts --out DIR
