+description: Guide for testing Codex TUI interactively
+---
+
+You can start and use Codex TUI to verify changes. 
+
+Important notes:
+
+Start interactively.
+Always set RUST_LOG="trace" when starting the process.
+Pass `-c log_dir=<some_temp_dir>` argument to have logs written to a specific directory to help with debugging.
+When sending a test message programmatically, send text first, then send Enter in a separate write (do not send text + Enter in one burst).
+Use `just codex` target to run - `just codex -c ...`

-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 `[]`.

+            - Prioritize concrete overlap in symptoms, reproduction details, error signatures, and user intent.
+            - Prefer active unresolved issues when confidence is similar.
+            - Closed issues can still be valid duplicates if they clearly match.
+            - Return fewer matches rather than speculative ones.
+            - If confidence is low, return an empty list.
+            - Include at most five issue numbers.

-# Rust/hanzo-dev
+# Rust/codex-rs
 
-The primary Rust workspace lives in `hanzo-dev/`:
+In the codex-rs folder where the rust code lives:
 
-- Crate names are prefixed with `hanzo-`. For example, the `core` folder's crate is named `hanzo-core`
-- The CLI binary is named `dev` (crate: `hanzo-dev`)
+- 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.
-- Treat `codex-rs` as a read-only mirror of `openai/codex:main`; edit Rust sources under `hanzo-dev/` instead.
+- 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`.
+- Do not create small helper methods that are referenced only once.
 
-Completion/build step
+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:
 
-- Always validate using `./build-fast.sh` from the repo root. This is the single required check and must pass cleanly.
-- `./build-fast.sh` can take 20+min to run from a cold cache!!! Please use long timeout when running `./build-fast.sh` or waiting for it to complete.
-- Policy: All errors AND all warnings must be fixed before you’re done. Treat any compiler warning as a failure and address it (rename unused vars with `_`, remove `mut`, delete dead code, etc.).
-- Do not run additional format/lint/test commands on completion (e.g., `just fmt`, `just fix`, `cargo test`) unless explicitly requested for a specific task.
-- ***NEVER run rustfmt***
-- Before pushing to `main`, run `./pre-release.sh` to mirror the release preflight (dev-fast build, CLI smokes, workspace nextest).
+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.
 
-Optional regression checks (recommended when touching the Rust workspace):
+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. Do not re-run tests after running `fix` or `fmt`.
 
-- `cargo nextest run --no-fail-fast` — runs all workspace tests with the TUI helpers automatically enabled. The suite is green after the resume fixtures/git-init fallback updates; older Git builds may print a warning when falling back from `--initial-branch`, but tests still pass.
-- Focused sweeps stay quick and green: `cargo test -p hanzo-tui --features test-helpers`, `cargo test -p hanzo-cloud-tasks --tests`, and `cargo test -p mcp-types --tests`.
+## TUI style conventions
 
-When debugging regressions or bugs, write a failing test (or targeted reproduction script) first and confirm it captures the issue before touching code—if it can’t fail, you can’t be confident the fix works.
+See `codex-rs/tui/styles.md`.
 
-## Documentation hygiene
+## TUI code conventions
 
-- Keep docs clean, clear, and current; prune stale instructions instead of piling on caveats.
-- Avoid excessive verbosity; prioritize concise guidance over long narratives.
-- Do not document minor or non-core features; focus on system-critical flows and expectations.
-- Never commit temporary "working" docs, plans, or scratch notes.
+- 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()]
 
-## Strict Ordering In The TUI History
+### TUI Styling (ratatui)
 
-The TUI enforces strict, per‑turn ordering for all streamed content. Every
-stream insert (Answer or Reasoning) must be associated with a stable
-`(request_ordinal, output_index, sequence_number)` key provided by the model.
+- 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.
 
-- A stream insert MUST carry a non‑empty stream id. The UI seeds an order key
-  for `(kind, id)` from the event's `OrderMeta` before any insert.
-- The TUI WILL NOT insert streaming content without a stream id. Any attempt to
-  insert without an id is dropped with an error log to make the issue visible
-  during development.
+### Text wrapping
 
-## Commit Messages
+- 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.
 
-- Review staged changes before every commit: `git --no-pager diff --staged --stat` (and skim `git --no-pager diff --staged` if needed).
-- Write a descriptive subject that explains what changed and why. Avoid placeholders like "chore: commit local work".
-- Prefer Conventional Commits with an optional scope: `feat(tui/history): …`, `fix(core/exec): …`, `docs(agents): …`.
-- Keep the subject ≤ 72 chars; add a short body if rationale or context helps future readers.
-- Use imperative, present tense: "add", "fix", "update" (not "added", "fixes").
-- For merge commits, skip custom prefixes like `merge(main<-origin/main):`. Use a clear subject such as `Merge origin/main: <what changed and how conflicts were resolved>`.
+## Tests
 
-Examples:
+### Snapshot tests
 
-- `feat(tui/history): show exit code and duration for Exec cells`
-- `fix(core/codex): handle SIGINT in on_exec_command_begin to avoid orphaned child`
-- `docs(agents): clarify commit-message expectations`
+This repo uses snapshot tests (via `insta`), especially in `codex-rs/tui`, to validate rendered output.
 
-## How to Git Push
+**Requirement:** any change that affects user-visible UI (including adding new UI) must include
+corresponding `insta` snapshot coverage (add a new snapshot test if one doesn't exist yet, or
+update the existing snapshot). Review and accept snapshot updates as part of the PR so UI impact
+is easy to review and future diffs stay visual.
 
-### Merge-and-Push Policy (Do Not Rebase)
+When UI or text output changes intentionally, update the snapshots as follows:
 
-When the user asks you to "push" local work:
+- 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`
 
-- Never rebase in this flow. Do not use `git pull --rebase` or attempt to replay local commits.
-- Prefer a simple merge of `origin/main` into the current branch, keeping our local history intact.
-- If the remote only has trivial release metadata changes (e.g., `codex-cli/package.json` version bumps), adopt the remote version for those files and keep ours for everything else unless the user specifies otherwise.
-- If in doubt or if conflicts touch non-trivial areas, pause and ask before resolving.
+If you don’t have the tool:
 
-Quick procedure (merge-only):
+- `cargo install cargo-insta`
 
-- Commit your local work first:
-  - Review: `git --no-pager diff --stat` and `git --no-pager diff`
-  - Stage + commit: `git add -A && git commit -m "<descriptive message of local changes>"`
-- Fetch remote: `git fetch origin`
-- Merge without auto-commit: `git merge --no-ff --no-commit origin/main` (stops before committing so you can choose sides)
-- Resolve policy:
-  - Default to ours: `git checkout --ours .`
-  - Take remote for trivial package/version files as needed, e.g.: `git checkout --theirs codex-cli/package.json`
-- Stage and commit the merge with a descriptive message, e.g.:
-  - `git add -A && git commit -m "Merge origin/main: adopt remote version bumps; keep ours elsewhere (<areas>)"`
-- Run `./build-fast.sh` and then `git push`
+### Test assertions
 
-## Command Execution Architecture
+- 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.
 
-The command execution flow in Codex follows an event-driven pattern:
+### Spawning workspace binaries in tests (Cargo vs Bazel)
 
-1. **Core Layer** (`codex-core/src/codex.rs`):
-   - `on_exec_command_begin()` initiates command execution
-   - Creates `EventMsg::ExecCommandBegin` events with command details
+- 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.
 
-2. **TUI Layer** (`codex-tui/src/chatwidget.rs`):
-   - `handle_codex_event()` processes execution events
-   - Manages `RunningCommand` state for active commands
-   - Creates `HistoryCell::Exec` for UI rendering
+### Integration tests (core)
 
-3. **History Cell** (`codex-tui/src/history_cell.rs`):
-   - `new_active_exec_command()` - Creates cell for running command
-   - `new_completed_exec_command()` - Updates with final output
-   - Handles syntax highlighting via `ParsedCommand`
+- Prefer the utilities in `core_test_support::responses` when writing end-to-end Codex tests.
 
-This architecture separates concerns between execution logic (core), UI state management (chatwidget), and rendering (history_cell).
+- 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`
 
-### Auto Drive Escape Handling
+- Typical pattern:
 
-- All Auto Drive escape routing lives in `hanzo-dev/tui/src/chatwidget.rs`. The
-  `ChatWidget::auto_should_handle_global_esc` helper decides whether the global
-  Esc handler in `app.rs` should defer to Auto Drive, and
-  `ChatWidget::handle_key_event` owns the actual stop / pause behaviour. When
-  you need to tweak Esc semantics, update those two locations together.
-- The approval pane must *never* swallow Esc. `hanzo-dev/tui/src/bottom_pane/auto_coordinator_view.rs`
-  intentionally lets Esc (and the other approval shortcuts) bubble back to the
-  chat widget; keep this contract intact when editing the view layer.
-- Avoid adding additional Esc handlers elsewhere for Auto Drive flows. Doing
-  so breaks the modal-first ordering in `app.rs` and prevents users from
-  reliably stopping a run.
+  ```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;
 
-## Writing New UI Regression Tests
+  codex.submit(Op::UserTurn { ... }).await?;
 
-- Start with `make_chatwidget_manual()` (or `make_chatwidget_manual_with_sender()`) to build a `ChatWidget` in isolation with in-memory channels.
-- Simulate user input by defining a small enum (`ScriptStep`) and feeding key events via `chat.handle_key_event()`; see `run_script()` in `tests.rs` for a ready-to-use helper that also pumps `AppEvent`s.
-- After the scripted interaction, render with a `ratatui::Terminal`/`TestBackend`, then use `buffer_to_string()` (wraps `strip_ansi_escapes`) to normalize ANSI output before asserting.
-- Prefer snapshot assertions (`assert_snapshot!`) or rich string comparisons so UI regressions are obvious. Keep snapshots deterministic by trimming trailing space and driving commit ticks just like the existing tests do.
-- When adding fixtures or updating snapshots, gate rewrites behind an opt-in env var (e.g., `UPDATE_IDEAL=1`) so baseline refreshes remain explicit.
+  // 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.
+  ```
 
-## VT100 Snapshot Harness
+## App-server API Development Best Practices
 
-- The VT100 harness lives under `hanzo-dev/tui/tests/vt100_chatwidget_snapshot.rs`. It renders the live `ChatWidget` UI into a `Terminal<VT100Backend>` so snapshots capture the exact PTY output the user sees (including frame chrome, composer rows, and streaming inserts).
-- Use `ChatWidgetHarness` helpers from `code_tui::test_helpers` to seed history events and drain `AppEvent`s. Call `render_chat_widget_to_vt100(width, height)` for a single frame, or `render_chat_widget_frames_to_vt100(&[(w,h), ...])` to simulate successive draws while streaming.
-- The harness now exports `layout_metrics()` so tests can assert scroll offsets and viewport heights without spelunking through private fields.
-- Snapshots are deterministic: tests set `CODEX_TUI_FAKE_HOUR=12` automatically so greeting text (“What can I code for you today?”) doesn’t oscillate. If you need a different hour in a test, override the env var before constructing the harness.
-- To add a new scenario, push history/events onto the harness, call `render_*_to_vt100`, and either `insta::assert_snapshot!` the frame(s) or manually assert string contents. For multi-frame streaming, push deltas/events first, then capture frames in the order the UI would display them.
-- Run all VT100 snapshots via:
-  - `cargo test -p code-tui --test vt100_chatwidget_snapshot --features test-helpers -- --nocapture`
-- When you intentionally change rendering, review the `.snap.new` files that appear in `hanzo-dev/tui/tests/snapshots/` and accept them with `cargo insta review` / `cargo insta accept` (limit to this test where possible).
+These guidelines apply to app-server protocol work in `codex-rs`, especially:
 
-### Monitor Release Workflows After Pushing
+- `app-server-protocol/src/protocol/common.rs`
+- `app-server-protocol/src/protocol/v2.rs`
+- `app-server/README.md`
 
-- Use `scripts/wait-for-gh-run.sh` to follow GitHub Actions releases without spamming manual `gh` commands.
-- Typical release check right after a push: `scripts/wait-for-gh-run.sh --workflow Release --branch main`.
-- If you already know the run ID (e.g., from webhook output), run `scripts/wait-for-gh-run.sh --run <run-id>`.
-- Adjust the poll cadence via `--interval <seconds>` (defaults to 8). The script exits 0 on success and 1 on failure, so it can gate local automation.
-- Pass `--failure-logs` to automatically dump logs for any job that does not finish successfully.
-- Dependencies: GitHub CLI (`gh`) and `jq` must be available in `PATH`.
+### 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.
+- Exception: config RPC payloads are expected to use snake_case to mirror config.toml keys (see the config read/write/list APIs in `app-server-protocol/src/protocol/v2.rs`).
+- 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<()>`.
+- 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.
+
+### Client->server request payloads (`*Params`)
+
+- Every optional field must be annotated with `#[ts(optional = nullable)]`. Do not use `#[ts(optional = nullable)]` outside client->server request payloads (`*Params`).
+- Optional collection fields (for example `Vec`, `HashMap`) must use `Option<...>` + `#[ts(optional = nullable)]`. Do not use `#[serde(default)]` to model optional collections, and do not use `skip_serializing_if` on v2 payload fields.
+- When you want omission to mean `false` for boolean fields, 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>`.
+
+### 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`.
+- Avoid boilerplate tests that only assert experimental field markers for individual
+  request fields in `common.rs`; rely on schema generation/tests and behavioral coverage instead.

 # App Server Test Client
-Exercises simple `codex app-server` flows end-to-end, logging JSON-RPC messages sent between client and server to stdout.
+Quickstart for running and hitting `codex app-server`.
+
+## Quickstart
+
+Run from `<reporoot>/codex-rs`.
+
+```bash
+# 1) Build debug codex binary
+cargo build -p codex-cli --bin codex
+
+# 2) Start websocket app-server in background
+cargo run -p codex-app-server-test-client -- \
+  --codex-bin ./target/debug/codex \
+  serve --listen ws://127.0.0.1:4222 --kill
+
+# 3) Call app-server (defaults to ws://127.0.0.1:4222)
+cargo run -p codex-app-server-test-client -- model-list
+```
+
+## Testing Thread Rejoin Behavior
+
+Build and start an app server using commands above. The app-server log is written to `/tmp/codex-app-server-test-client/app-server.log`
+
+### 1) Get a thread id
+
+Create at least one thread, then list threads:
+
+```bash
+cargo run -p codex-app-server-test-client -- send-message-v2 "seed thread for rejoin test"
+cargo run -p codex-app-server-test-client -- thread-list --limit 5
+```
+
+Copy a thread id from the `thread-list` output.
+
+### 2) Rejoin while a turn is in progress (two terminals)
+
+Terminal A:
+
+```bash
+cargo run --bin codex-app-server-test-client -- \
+  resume-message-v2 <THREAD_ID> "respond with thorough docs on the rust core"
+```
+
+Terminal B (while Terminal A is still streaming):
+
+```bash
+cargo run --bin codex-app-server-test-client -- thread-resume <THREAD_ID>
+```

 ## Protocol

+Similar to [MCP](https://modelcontextprotocol.io/), `codex app-server` supports bidirectional communication using JSON-RPC 2.0 messages (with the `"jsonrpc":"2.0"` header omitted on the wire).
+
+Supported transports:
+
+- stdio (`--listen stdio://`, default): newline-delimited JSON (JSONL)
+- websocket (`--listen ws://IP:PORT`): one JSON-RPC message per websocket text frame (**experimental / unsupported**)
+
+Websocket transport is currently experimental and unsupported. Do not rely on it for production workloads.
+
+Backpressure behavior:
+
+- The server uses bounded queues between transport ingress, request processing, and outbound writes.
+- When request ingress is saturated, new requests are rejected with a JSON-RPC error code `-32001` and message `"Server overloaded; retry later."`.
+- Clients should treat this as retryable and use exponential backoff with jitter.

+- Initialize once per connection: Immediately after opening a transport connection, send an `initialize` request with your client metadata, then emit an `initialized` notification. Any other request on that connection 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. If you want to branch from an existing conversation, call `thread/fork` to create a new thread id with copied history.
 - 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).

 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` status). Token usage events stream separately via `thread/tokenUsage/updated`. Clients subscribe to the events they care about, rendering each item incrementally as updates arrive.
