  • feat: sqlite 1 (#10004)
    Add a `.sqlite` database to be used to store rollout metatdata (and
    later logs)
    This PR is phase 1:
    * Add the database and the required infrastructure
    * Add a backfill of the database
    * Persist the newly created rollout both in files and in the DB
    * When we need to get metadata or a rollout, consider the `JSONL` as the
    source of truth but compare the results with the DB and show any errors
  • feat(core) ModelInfo.model_instructions_template (#9597)
    ## Summary
    #9555 is the start of a rename, so I'm starting to standardize here.
    Sets up `model_instructions` templating with a strongly-typed object for
    injecting a personality block into the model instructions.
    
    ## Testing
    - [x] Added tests
    - [x] Ran locally

  • Fix: Improve text encoding for shell output in VSCode preview (#6178) (#6182)
    ## 🐛 Problem
    
    Users running commands with non-ASCII characters (like Russian text
    "пример") in Windows/WSL environments experience garbled text in
    VSCode's shell preview window, with Unicode replacement characters (�)
    appearing instead of the actual text.
    
    **Issue**: https://github.com/openai/codex/issues/6178
    
    ## 🔧 Root Cause
    
    The issue was in `StreamOutput<Vec<u8>>::from_utf8_lossy()` method in
    `codex-rs/core/src/exec.rs`, which used `String::from_utf8_lossy()` to
    convert shell output bytes to strings. This function immediately
    replaces any invalid UTF-8 byte sequences with replacement characters,
    without attempting to decode using other common encodings.
    
    In Windows/WSL environments, shell output often uses encodings like:
    
    - Windows-1252 (common Windows encoding)
    - Latin-1/ISO-8859-1 (extended ASCII)
    
    ## 🛠️ Solution
    
    Replaced the simple `String::from_utf8_lossy()` call with intelligent
    encoding detection via a new `bytes_to_string_smart()` function that
    tries multiple encoding strategies:
    
    1. **UTF-8** (fast path for valid UTF-8)
    2. **Windows-1252** (handles Windows-specific characters in 0x80-0x9F
    range)
    3. **Latin-1** (fallback for extended ASCII)
    4. **Lossy UTF-8** (final fallback, same as before)
    
    ## 📁 Changes
    
    ### New Files
    
    - `codex-rs/core/src/text_encoding.rs` - Smart encoding detection module
    - `codex-rs/core/tests/suite/text_encoding_fix.rs` - Integration tests
    
    ### Modified Files
    
    - `codex-rs/core/src/lib.rs` - Added text_encoding module
    - `codex-rs/core/src/exec.rs` - Updated StreamOutput::from_utf8_lossy()
    - `codex-rs/core/tests/suite/mod.rs` - Registered new test module
    
    ##  Testing
    
    - **5 unit tests** covering UTF-8, Windows-1252, Latin-1, and fallback
    scenarios
    - **2 integration tests** simulating the exact Issue #6178 scenario
    - **Demonstrates improvement** over the previous
    `String::from_utf8_lossy()` approach
    
    All tests pass:
    
    ```bash
    cargo test -p codex-core text_encoding
    cargo test -p codex-core test_shell_output_encoding_issue_6178
    ```
    
    ## 🎯 Impact
    
    -  **Eliminates garbled text** in VSCode shell preview for non-ASCII
    content
    -  **Supports Windows/WSL environments** with proper encoding detection
    -  **Zero performance impact** for UTF-8 text (fast path)
    -  **Backward compatible** - UTF-8 content works exactly as before
    -  **Handles edge cases** with robust fallback mechanism
    
    ## 🧪 Test Scenarios
    
    The fix has been tested with:
    
    - Russian text ("пример")
    - Windows-1252 quotation marks (""test")
    - Latin-1 accented characters ("café")
    - Mixed encoding content
    - Invalid byte sequences (graceful fallback)

  • chore(core) Consolidate apply_patch tests (#6545)
    ## Summary
    Consolidates our apply_patch tests into one suite, and ensures each test
    case tests the various ways the harness supports apply_patch:
    1. Freeform custom tool call
    2. JSON function tool
    3. Simple shell call
    4. Heredoc shell call
    
    There are a few test cases that are specific to a particular variant,
    I've left those alone.
    
    ## Testing
    - [x] This adds a significant number of tests
  • Use codex-linux-sandbox in unified exec (#6480)
    Unified exec isn't working on Linux because we don't provide the correct
    arg0.
    
    The library we use for pty management doesn't allow setting arg0
    separately from executable. Use the same aliasing strategy we use for
    `apply_patch` for `codex-linux-sandbox`.
    
    Use `#[ctor]` hack to dispatch codex-linux-sandbox calls.

  • Don't retry "insufficient_quota" errors (#6340)
    This PR makes an "insufficient quota" error fatal so we don't attempt to
    retry it multiple times in the agent loop.
    
    We have multiple bug reports from users about intermittent retry
    behaviors, and this could explain some of them. With this change, we'll
    eliminate the retries and surface a clear error message.
    
    The PR is a nearly identical copy of [this
    PR](https://github.com/openai/codex/pull/4837) contributed by
    @abimaelmartell. The original PR has gone stale. Rather than wait for
    the contributor to resolve merge conflicts, I wanted to get this change
    in.
  • Improved token refresh handling to address "Re-connecting" behavior (#6231)
    Currently, when the access token expires, we attempt to use the refresh
    token to acquire a new access token. This works most of the time.
    However, there are situations where the refresh token is expired,
    exhausted (already used to perform a refresh), or revoked. In those
    cases, the current logic treats the error as transient and attempts to
    retry it repeatedly.
    
    This PR changes the token refresh logic to differentiate between
    permanent and transient errors. It also changes callers to treat the
    permanent errors as fatal rather than retrying them. And it provides
    better error messages to users so they understand how to address the
    problem. These error messages should also help us further understand why
    we're seeing examples of refresh token exhaustion.
    
    Here is the error message in the CLI. The same text appears within the
    extension.
    
    <img width="863" height="38" alt="image"
    src="https://github.com/user-attachments/assets/7ffc0d08-ebf0-4900-b9a9-265064202f4f"
    />
    
    I also correct the spelling of "Re-connecting", which shouldn't have a
    hyphen in it.
    
    Testing: I manually tested these code paths by adding temporary code to
    programmatically cause my refresh token to be exhausted (by calling the
    token refresh endpoint in a tight loop more than 50 times). I then
    simulated an access token expiration, which caused the token refresh
    logic to be invoked. I confirmed that the updated logic properly handled
    the error condition.
    
    Note: We earlier discussed the idea of forcefully logging out the user
    at the point where token refresh failed. I made several attempts to do
    this, and all of them resulted in a bad UX. It's important to surface
    this error to users in a way that explains the problem and tells them
    that they need to log in again. We also previously discussed deleting
    the auth.json file when this condition is detected. That also creates
    problems because it effectively changes the auth status from logged in
    to logged out, and this causes odd failures and inconsistent UX. I think
    it's therefore better not to delete auth.json in this case. If the user
    closes the CLI or VSCE and starts it again, we properly detect that the
    access token is expired and the refresh token is "dead", and we force
    the user to go through the login flow at that time.
    
    This should address aspects of #6191, #5679, and #5505
  • chore: testing on freeform apply_patch (#5952)
    ## Summary
    Duplicates the tests in `apply_patch_cli.rs`, but tests the freeform
    apply_patch tool as opposed to the function call path. The good news is
    that all the tests pass with zero logical tests, with the exception of
    the heredoc, which doesn't really make sense in the freeform tool
    context anyway.
    
    @jif-oai since you wrote the original tests in #5557, I'd love your
    opinion on the right way to DRY these test cases between the two. Happy
    to set up a more sophisticated harness, but didn't want to go down the
    rabbit hole until we agreed on the right pattern
    
    ## Testing

  • Delegate review to codex instance (#5572)
    In this PR, I am exploring migrating task kind to an invocation of
    Codex. The main reason would be getting rid off multiple
    `ConversationHistory` state and streamlining our context/history
    management.
    
    This approach depends on opening a channel between the sub-codex and
    codex. This channel is responsible for forwarding `interactive`
    (`approvals`) and `non-interactive` events. The `task` is responsible
    for handling those events.
    
    This opens the door for implementing `codex as a tool`, replacing
    `compact` and `review`, and potentially subagents.
    
    One consideration is this code is very similar to `app-server` specially
    in the approval part. If in the future we wanted an interactive
    `sub-codex` we should consider using `codex-mcp`

  • feature: Add "!cmd" user shell execution (#2471)
    feature: Add "!cmd" user shell execution
    
    This change lets users run local shell commands directly from the TUI by
    prefixing their input with ! (e.g. !ls). Output is truncated to keep the
    exec cell usable, and Ctrl-C cleanly
      interrupts long-running commands (e.g. !sleep 10000).
    
    **Summary of changes**
    
    - Route Op::RunUserShellCommand through a dedicated UserShellCommandTask
    (core/src/tasks/user_shell.rs), keeping the task logic out of codex.rs.
    - Reuse the existing tool router: the task constructs a ToolCall for the
    local_shell tool and relies on ShellHandler, so no manual MCP tool
    lookup is required.
    - Emit exec lifecycle events (ExecCommandBegin/ExecCommandEnd) so the
    TUI can show command metadata, live output, and exit status.
    
    **End-to-end flow**
    
      **TUI handling**
    
    1. ChatWidget::submit_user_message (TUI) intercepts messages starting
    with !.
    2. Non-empty commands dispatch Op::RunUserShellCommand { command };
    empty commands surface a help hint.
    3. No UserInput items are created, so nothing is enqueued for the model.
    
      **Core submission loop**
    4. The submission loop routes the op to handlers::run_user_shell_command
    (core/src/codex.rs).
    5. A fresh TurnContext is created and Session::spawn_user_shell_command
    enqueues UserShellCommandTask.
    
      **Task execution**
    6. UserShellCommandTask::run emits TaskStartedEvent, formats the
    command, and prepares a ToolCall targeting local_shell.
      7. ToolCallRuntime::handle_tool_call dispatches to ShellHandler.
    
      **Shell tool runtime**
    8. ShellHandler::run_exec_like launches the process via the unified exec
    runtime, honoring sandbox and shell policies, and emits
    ExecCommandBegin/End.
    9. Stdout/stderr are captured for the UI, but the task does not turn the
    resulting ToolOutput into a model response.
    
      **Completion**
    10. After ExecCommandEnd, the task finishes without an assistant
    message; the session marks it complete and the exec cell displays the
    final output.
    
      **Conversation context**
    
    - The command and its output never enter the conversation history or the
    model prompt; the flow is local-only.
      - Only exec/task events are emitted for UI rendering.

    Add parallel tool calls. This is configurable at model level and tool
    level
  • feat: Freeform apply_patch with simple shell output (#4718)
    ## Summary
    This PR is an alternative approach to #4711, but instead of changing our
    storage, parses out shell calls in the client and reserializes them on
    the fly before we send them out as part of the request.
    
    What this changes:
    1. Adds additional serialization logic when the
    ApplyPatchToolType::Freeform is in use.
    2. Adds a --custom-apply-patch flag to enable this setting on a
    session-by-session basis.
    
    This change is delicate, but is not meant to be permanent. It is meant
    to be the first step in a migration:
    1. (This PR) Add in-flight serialization with config
    2. Update model_family default
    3. Update serialization logic to store turn outputs in a structured
    format, with logic to serialize based on model_family setting.
    4. Remove this rewrite in-flight logic.
    
    ## Test Plan
    - [x] Additional unit tests added
    - [x] Integration tests added
    - [x] Tested locally
  • chore: refactor tool handling (#4510)
    # Tool System Refactor
    
    - Centralizes tool definitions and execution in `core/src/tools/*`:
    specs (`spec.rs`), handlers (`handlers/*`), router (`router.rs`),
    registry/dispatch (`registry.rs`), and shared context (`context.rs`).
    One registry now builds the model-visible tool list and binds handlers.
    - Router converts model responses to tool calls; Registry dispatches
    with consistent telemetry via `codex-rs/otel` and unified error
    handling. Function, Local Shell, MCP, and experimental `unified_exec`
    all flow through this path; legacy shell aliases still work.
    - Rationale: reduce per‑tool boilerplate, keep spec/handler in sync, and
    make adding tools predictable and testable.
    
    Example: `read_file`
    - Spec: `core/src/tools/spec.rs` (see `create_read_file_tool`,
    registered by `build_specs`).
    - Handler: `core/src/tools/handlers/read_file.rs` (absolute `file_path`,
    1‑indexed `offset`, `limit`, `L#: ` prefixes, safe truncation).
    - E2E test: `core/tests/suite/read_file.rs` validates the tool returns
    the requested lines.
    
    ## Next steps:
    - Decompose `handle_container_exec_with_params` 
    - Add parallel tool calls
  • OpenTelemetry events (#2103)
    ### Title
    
    ## otel
    
    Codex can emit [OpenTelemetry](https://opentelemetry.io/) **log events**
    that
    describe each run: outbound API requests, streamed responses, user
    input,
    tool-approval decisions, and the result of every tool invocation. Export
    is
    **disabled by default** so local runs remain self-contained. Opt in by
    adding an
    `[otel]` table and choosing an exporter.
    
    ```toml
    [otel]
    environment = "staging"   # defaults to "dev"
    exporter = "none"          # defaults to "none"; set to otlp-http or otlp-grpc to send events
    log_user_prompt = false    # defaults to false; redact prompt text unless explicitly enabled
    ```
    
    Codex tags every exported event with `service.name = "codex-cli"`, the
    CLI
    version, and an `env` attribute so downstream collectors can distinguish
    dev/staging/prod traffic. Only telemetry produced inside the
    `codex_otel`
    crate—the events listed below—is forwarded to the exporter.
    
    ### Event catalog
    
    Every event shares a common set of metadata fields: `event.timestamp`,
    `conversation.id`, `app.version`, `auth_mode` (when available),
    `user.account_id` (when available), `terminal.type`, `model`, and
    `slug`.
    
    With OTEL enabled Codex emits the following event types (in addition to
    the
    metadata above):
    
    - `codex.api_request`
      - `cf_ray` (optional)
      - `attempt`
      - `duration_ms`
      - `http.response.status_code` (optional)
      - `error.message` (failures)
    - `codex.sse_event`
      - `event.kind`
      - `duration_ms`
      - `error.message` (failures)
      - `input_token_count` (completion only)
      - `output_token_count` (completion only)
      - `cached_token_count` (completion only, optional)
      - `reasoning_token_count` (completion only, optional)
      - `tool_token_count` (completion only)
    - `codex.user_prompt`
      - `prompt_length`
      - `prompt` (redacted unless `log_user_prompt = true`)
    - `codex.tool_decision`
      - `tool_name`
      - `call_id`
    - `decision` (`approved`, `approved_for_session`, `denied`, or `abort`)
      - `source` (`config` or `user`)
    - `codex.tool_result`
      - `tool_name`
      - `call_id`
      - `arguments`
      - `duration_ms` (execution time for the tool)
      - `success` (`"true"` or `"false"`)
      - `output`
    
    ### Choosing an exporter
    
    Set `otel.exporter` to control where events go:
    
    - `none` – leaves instrumentation active but skips exporting. This is
    the
      default.
    - `otlp-http` – posts OTLP log records to an OTLP/HTTP collector.
    Specify the
      endpoint, protocol, and headers your collector expects:
    
      ```toml
      [otel]
      exporter = { otlp-http = {
        endpoint = "https://otel.example.com/v1/logs",
        protocol = "binary",
        headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" }
      }}
      ```
    
    - `otlp-grpc` – streams OTLP log records over gRPC. Provide the endpoint
    and any
      metadata headers:
    
      ```toml
      [otel]
      exporter = { otlp-grpc = {
        endpoint = "https://otel.example.com:4317",
        headers = { "x-otlp-meta" = "abc123" }
      }}
      ```
    
    If the exporter is `none` nothing is written anywhere; otherwise you
    must run or point to your
    own collector. All exporters run on a background batch worker that is
    flushed on
    shutdown.
    
    If you build Codex from source the OTEL crate is still behind an `otel`
    feature
    flag; the official prebuilt binaries ship with the feature enabled. When
    the
    feature is disabled the telemetry hooks become no-ops so the CLI
    continues to
    function without the extra dependencies.

  • [MCP] Introduce an experimental official rust sdk based mcp client (#4252)
    The [official Rust
    SDK](https://github.com/modelcontextprotocol/rust-sdk/tree/57fc428c578a1a3fe851ee0838bf068bda120eb3)
    has come a long way since we first started our mcp client implementation
    5 months ago and, today, it is much more complete than our own
    stdio-only implementation.
    
    This PR introduces a new config flag `experimental_use_rmcp_client`
    which will use a new mcp client powered by the sdk instead of our own.
    
    To keep this PR simple, I've only implemented the same stdio MCP
    functionality that we had but will expand on it with future PRs.
