  • Split features into codex-features crate (#15253)
    - Split the feature system into a new `codex-features` crate.
    - Cut `codex-core` and workspace consumers over to the new config and
    warning APIs.

  • Apply argument comment lint across codex-rs (#14652)
    ## Why
    
    Once the repo-local lint exists, `codex-rs` needs to follow the
    checked-in convention and CI needs to keep it from drifting. This commit
    applies the fallback `/*param*/` style consistently across existing
    positional literal call sites without changing those APIs.
    
    The longer-term preference is still to avoid APIs that require comments
    by choosing clearer parameter types and call shapes. This PR is
    intentionally the mechanical follow-through for the places where the
    existing signatures stay in place.
    
    After rebasing onto newer `main`, the rollout also had to cover newly
    introduced `tui_app_server` call sites. That made it clear the first cut
    of the CI job was too expensive for the common path: it was spending
    almost as much time installing `cargo-dylint` and re-testing the lint
    crate as a representative test job spends running product tests. The CI
    update keeps the full workspace enforcement but trims that extra
    overhead from ordinary `codex-rs` PRs.
    
    ## What changed
    
    - keep a dedicated `argument_comment_lint` job in `rust-ci`
    - mechanically annotate remaining opaque positional literals across
    `codex-rs` with exact `/*param*/` comments, including the rebased
    `tui_app_server` call sites that now fall under the lint
    - keep the checked-in style aligned with the lint policy by using
    `/*param*/` and leaving string and char literals uncommented
    - cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
    registry/git metadata in the lint job
    - split changed-path detection so the lint crate's own `cargo test` step
    runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
    - continue to run the repo wrapper over the `codex-rs` workspace, so
    product-code enforcement is unchanged
    
    Most of the code changes in this commit are intentionally mechanical
    comment rewrites or insertions driven by the lint itself.
    
    ## Verification
    
    - `./tools/argument-comment-lint/run.sh --workspace`
    - `cargo test -p codex-tui-app-server -p codex-tui`
    - parsed `.github/workflows/rust-ci.yml` locally with PyYAML

  • move plugin/skill instructions into dev msg and reorder (#14609)
    Move the general `Apps`, `Skills` and `Plugins` instructions blocks out
    of `user_instructions` and into the developer message, with new `Apps ->
    Skills -> Plugins` order for better clarity.
    
    Also wrap those sections in stable XML-style instruction tags (like
    other sections) and update prompt-layout tests/snapshots. This makes the
    tests less brittle in snapshot output (we can parse the sections), and
    it consolidates the capability instructions in one place.
    
    #### Tests
    Updated snapshots, added tests.
    
    `<AGENTS_MD>` disappearing in snapshots is expected: before this change,
    the wrapped user-instructions message was kept alive by `Skills`
    content. Now that `Skills` and `Plugins` are in the developer message,
    that wrapper only appears when there is real
    project-doc/user-instructions content.

  • feat(app-server, core): add more spans (#14479)
    ## Description
    
    This PR expands tracing coverage across app-server thread startup, core
    session initialization, and the Responses transport layer. It also gives
    core dispatch spans stable operation-specific names so traces are easier
    to follow than the old generic `submission_dispatch` spans.
    
    Also use `fmt::Display` for types that we serialize in traces so we send
    strings instead of rust types
  • Persist js_repl codex helpers across cells (#14503)
    ## Summary
    
    This changes `js_repl` so saved references to `codex.tool(...)` and
    `codex.emitImage(...)` keep working across cells.
    
    Previously, those helpers were recreated per exec and captured that
    exec's `message.id`. If a persisted object or saved closure reused an
    old helper in a later cell, the nested tool/image call could fail with
    `js_repl exec context not found`.
    
    This patch:
    - keeps stable `codex.tool` and `codex.emitImage` helper identities in
    the kernel
    - resolves the current exec dynamically at call time using
    `AsyncLocalStorage`
    - adds regression coverage for persisted helper references across cells
    - updates the js_repl docs and project-doc instructions to describe the
    new behavior and its limits
    
    ## Why
    
    We already support persistent top-level bindings across `js_repl` cells,
    so persisted objects should be able to reuse `codex` helpers in later
    active cells. The bug was that helper identity was exec-scoped, not
    kernel-scoped.
    
    Using `AsyncLocalStorage` fixes the cross-cell reuse case without
    falling back to a single global active exec that could accidentally
    attribute stale background callbacks to the wrong cell.
  • Cleanup code_mode tool descriptions (#14480)
    Move to separate files and clarify a bit.
  • fix: move inline codex-rs/core unit tests into sibling files (#14444)
    ## Why
    PR #13783 moved the `codex.rs` unit tests into `codex_tests.rs`. This
    applies the same extraction pattern across the rest of `codex-rs/core`
    so the production modules stay focused on runtime code instead of large
    inline test blocks.
    
    Keeping the tests in sibling files also makes follow-up edits easier to
    review because product changes no longer have to share a file with
    hundreds or thousands of lines of test scaffolding.
    
    ## What changed
    - replaced each inline `mod tests { ... }` in `codex-rs/core/src/**`
    with a path-based module declaration
    - moved each extracted unit test module into a sibling `*_tests.rs`
    file, using `mod_tests.rs` for `mod.rs` modules
    - preserved the existing `cfg(...)` guards and module-local structure so
    the refactor remains structural rather than behavioral
    
    ## Testing
    - `cargo test -p codex-core --lib` (`1653 passed; 0 failed; 5 ignored`)
    - `just fix -p codex-core`
    - `cargo fmt --check`
    - `cargo shear`
  • Let models opt into original image detail (#14175)
    ## Summary
    
    This PR narrows original image detail handling to a single opt-in
    feature:
    
    - `image_detail_original` lets the model request `detail: "original"` on
    supported models
    - Omitting `detail` preserves the default resized behavior
    
    The model only sees `detail: "original"` guidance when the active model
    supports it:
    
    - JS REPL instructions include the guidance and examples only on
    supported models
    - `view_image` only exposes a `detail` parameter when the feature and
    model can use it
    
    The image detail API is intentionally narrow and consistent across both
    paths:
    
    - `view_image.detail` supports only `"original"`; otherwise omit the
    field
    - `codex.emitImage(..., detail)` supports only `"original"`; otherwise
    omit the field
    - Unsupported explicit values fail clearly at the API boundary instead
    of being silently reinterpreted
    - Unsupported explicit `detail: "original"` requests fall back to normal
    behavior when the feature is disabled or the model does not support
    original detail
  • Add js_repl cwd and homeDir helpers (#14385)
    ## Summary
    
    This PR adds two read-only path helpers to `js_repl`:
    
    - `codex.cwd`
    - `codex.homeDir`
    
    They are exposed alongside the existing `codex.tmpDir` helper so the
    REPL can reference basic host path context without reopening direct
    `process` access.
    
    ## Implementation
    
    - expose `codex.cwd` and `codex.homeDir` from the js_repl kernel
    - make `codex.homeDir` come from the kernel process environment
    - pass session dependency env through js_repl kernel startup so
    `codex.homeDir` matches the env a shell-launched process would see
    - keep existing shell `HOME` population behavior unchanged
    - update js_repl prompt/docs and add runtime/integration coverage for
    the new helpers
  • Add code_mode experimental feature (#13418)
    A much narrower and more isolated (no node features) version of js_repl
  • Clarify js_repl binding reuse guidance (#13803)
    ## Summary
    
    Clarify the `js_repl` prompt guidance around persistent bindings and
    redeclaration recovery.
    
    This updates the generated `js_repl` instructions in
    `core/src/project_doc.rs` to prefer this order when a name is already
    bound:
    
    1. Reuse the existing binding
    2. Reassign a previously declared `let`
    3. Pick a new descriptive name
    4. Use `{ ... }` only for short-lived scratch scope
    5. Reset the kernel only when a clean state is actually needed
    
    The prompt now also explicitly warns against wrapping an entire cell in
    block scope when the goal is to reuse names across later cells.
    
    ## Why
    
    The previous wording still left too much room for low-value workarounds
    like whole-cell block wrapping. In downstream browser rollouts, that
    pattern was adding tokens and preventing useful state reuse across
    `js_repl` cells.
    
    This change makes the preferred behavior more explicit without changing
    runtime semantics.
    
    ## Scope
    
    - Prompt/documentation change only
    - No runtime behavior changes
    - Updates the matching string-backed `project_doc` tests
  • Clarify js_repl image emission and encoding guidance (#13639)
    ## Summary
    
    This updates the `js_repl` prompt and docs to make the image guidance
    less confusing.
    
    ## What changed
    
    - Clarified that `codex.emitImage(...)` adds one image per call and can
    be called multiple times to emit multiple images.
    - Reworded the image-encoding guidance to be general `js_repl` advice
    instead of `ImageDetailOriginal`-specific behavior.
    - Updated the guidance to recommend JPEG at about quality 85 when lossy
    compression is acceptable, and PNG when transparency or lossless detail
    matters.
    - Mirrored the same wording in the public `js_repl` docs.
  • Harden js_repl emitImage to accept only data: URLs (#13507)
    ### Motivation
    
    - Prevent untrusted js_repl code from supplying arbitrary external URLs
    that the host would forward into model input and cause external fetches
    / data exfiltration. This change narrows the emitImage contract to safe,
    self-contained data URLs.
    
    ### Description
    
    - Kernel: added `normalizeEmitImageUrl` and enforce that string-valued
    `codex.emitImage(...)` inputs and `input_image`/content-item paths only
    accept non-empty `data:` URLs; byte-based paths still produce data URLs
    as before (`kernel.js`).
    - Host: added `validate_emitted_image_url` and check `EmitImage`
    requests before creating `FunctionCallOutputContentItem::InputImage`,
    returning an error to the kernel if the URL is not a `data:` URL
    (`mod.rs`).
    - Tests/docs: added a runtime test
    `js_repl_emit_image_rejects_non_data_url` to assert rejection of
    non-data URLs and updated user-facing docs/instruction text to state
    `data URL` support instead of generic direct image URLs (`mod.rs`,
    `docs/js_repl.md`, `project_doc.rs`).
    
    ### Testing
    
    - Ran `just fmt` in `codex-rs`; it completed successfully.
    - Added a runtime test (`cargo test -p codex-core
    js_repl_emit_image_rejects_non_data_url`) but executing the test in this
    environment failed due to a missing system dependency required by
    `codex-linux-sandbox` (the vendored `bubblewrap` build requires
    `libcap.pc` via `pkg-config`), so the test could not be run here.
    - Attempted a focused `cargo test` invocation with and without default
    features; both compile/test attempts were blocked by the same missing
    system `libcap` dependency in this environment.

  • Persist initialized js_repl bindings after failed cells (#13482)
    ## Summary
    
    - Change `js_repl` failed-cell persistence so later cells keep prior
    bindings plus only the current-cell bindings whose initialization
    definitely completed before the throw.
    - Preserve initialized lexical bindings across failed cells via
    module-namespace readability, including top-level destructuring that
    partially succeeds before a later throw.
    - Preserve hoisted `var` and `function` bindings only when execution
    clearly reached their declaration site, and preserve direct top-level
    pre-declaration `var` writes and updates through explicit write-site
    markers.
    - Preserve top-level `for...in` / `for...of` `var` bindings when the
    loop body executes at least once, using a first-iteration guard to avoid
    per-iteration bookkeeping overhead.
    - Keep prior module state intact across link-time failures and
    evaluation failures before the prelude runs, while still allowing failed
    cells that already recreated prior bindings to persist updates to those
    existing bindings.
    - Hide internal commit hooks from user `js_repl` code after the prelude
    aliases them, so snippets cannot spoof committed bindings by calling the
    raw `import.meta` hooks directly.
    - Add focused regression coverage for the supported failed-cell
    behaviors and the intentionally unsupported boundaries.
    - Update `js_repl` docs and generated instructions to describe the new,
    narrower failed-cell persistence model.
    
    ## Motivation
    
    We saw `js_repl` drop bindings that had already been initialized
    successfully when a later statement in the same cell threw, for example:
    
        const { context: liveContext, session } =
          await initializeGoogleSheetsLiveForTab(tab);
        // later statement throws
    
    That was surprising in practice because successful earlier work
    disappeared from the next cell.
    
    This change makes failed-cell persistence more useful without trying to
    model every possible partially executed JavaScript edge case. The
    resulting behavior is narrower and easier to reason about:
    
    - prior bindings are always preserved
    - lexical bindings persist when their initialization completed before
    the throw
    - hoisted `var` / `function` bindings persist only when execution
    clearly reached their declaration or a supported top-level `var` write
    site
    - failed cells that already recreated prior bindings can persist writes
    to those existing bindings even if they introduce no new bindings
    
    The detailed edge-case matrix stays in `docs/js_repl.md`. The
    model-facing `project_doc` guidance is intentionally shorter and focused
    on generation-relevant behavior.
    
    ## Supported Failed-Cell Behavior
    
    - Prior bindings remain available after a failed cell.
    - Initialized lexical bindings remain available after a failed cell.
    - Top-level destructuring like `const { a, b } = ...` preserves names
    whose initialization completed before a later throw.
    - Hoisted `function` bindings persist when execution reached the
    declaration statement before the throw.
    - Direct top-level pre-declaration `var` writes and updates persist, for
    example:
      - `x = 1`
      - `x += 1`
      - `x++`
    - short-circuiting logical assignments only persist when the write
    branch actually runs
    - Non-empty top-level `for...in` / `for...of` `var` loops persist their
    loop bindings.
    - Failed cells can persist updates to existing carried bindings after
    the prelude has run, even when the cell commits no new bindings.
    - Link failures and eval failures before the prelude do not poison
    `@prev`.
    
    ## Intentionally Unsupported Failed-Cell Cases
    
    - Hoisted function reads before the declaration, such as `foo(); ...;
    function foo() {}`
    - Aliasing or inference-based recovery from reads before declaration
    - Nested writes inside already-instrumented assignment RHS expressions
    - Destructuring-assignment recovery for hoisted `var`
    - Partial `var` destructuring recovery
    - Pre-declaration `undefined` reads for hoisted `var`
    - Empty top-level `for...in` / `for...of` loop vars
    - Nested or scope-sensitive pre-declaration `var` writes outside direct
    top-level expression statements
  • [js_repl] Support local ESM file imports (#13437)
    ## Summary
    - add `js_repl` support for dynamic imports of relative and absolute
    local ESM `.js` / `.mjs` files
    - keep bare package imports on the native Node path and resolved from
    REPL-global search roots (`CODEX_JS_REPL_NODE_MODULE_DIRS`, then `cwd`),
    even when they originate from imported local files
    - restrict static imports inside imported local files to other local
    relative/absolute `.js` / `.mjs` files, and surface a clear error for
    unsupported top-level static imports in the REPL cell
    - run imported local files inside the REPL VM context so they can access
    `codex.tmpDir`, `codex.tool`, captured `console`, and Node-like
    `import.meta` helpers
    - reload local files between execs so later `await import("./file.js")`
    calls pick up edits and fixed failures, while preserving package/builtin
    caching and persistent top-level REPL bindings
    - make `import.meta.resolve()` self-consistent by allowing the returned
    `file://...` URLs to round-trip through `await import(...)`
    - update both public and injected `js_repl` docs to clarify the narrowed
    contract, including global bare-import resolution behavior for local
    absolute files
    
    ## Testing
    - `cargo test -p codex-core js_repl_`
    - built codex binary and verified behavior

  • feat: track plugins mcps/apps and add plugin info to user_instructions (#13433)
    ### first half of changes, followed by #13510
    
    Track plugin capabilities as derived summaries on `PluginLoadOutcome`
    for enabled plugins with at least one skill/app/mcp.
    
    Also add `Plugins` section to `user_instructions` injected on session
    start. These introduce the plugins concept and list enabled plugins, but
    do NOT currently include paths to enabled plugins or details on what
    apps/mcps the plugins contain (current plan is to inject this on
    @-mention). that can be adjusted in a follow up and based on evals.
    
    ### tests
    Added/updated tests, confirmed locally that new `Plugins` section +
    currently enabled plugins show up in `user_instructions`.
  • config: enforce enterprise feature requirements (#13388)
    ## Why
    
    Enterprises can already constrain approvals, sandboxing, and web search
    through `requirements.toml` and MDM, but feature flags were still only
    configurable as managed defaults. That meant an enterprise could suggest
    feature values, but it could not actually pin them.
    
    This change closes that gap and makes enterprise feature requirements
    behave like the other constrained settings. The effective feature set
    now stays consistent with enterprise requirements during config load,
    when config writes are validated, and when runtime code mutates feature
    flags later in the session.
    
    It also tightens the runtime API for managed features. `ManagedFeatures`
    now follows the same constraint-oriented shape as `Constrained<T>`
    instead of exposing panic-prone mutation helpers, and production code
    can no longer construct it through an unconstrained `From<Features>`
    path.
    
    The PR also hardens the `compact_resume_fork` integration coverage on
    Windows. After the feature-management changes,
    `compact_resume_after_second_compaction_preserves_history` was
    overflowing the libtest/Tokio thread stacks on Windows, so the test now
    uses an explicit larger-stack harness as a pragmatic mitigation. That
    may not be the ideal root-cause fix, and it merits a parallel
    investigation into whether part of the async future chain should be
    boxed to reduce stack pressure instead.
    
    ## What Changed
    
    Enterprises can now pin feature values in `requirements.toml` with the
    requirements-side `features` table:
    
    ```toml
    [features]
    personality = true
    unified_exec = false
    ```
    
    Only canonical feature keys are allowed in the requirements `features`
    table; omitted keys remain unconstrained.
    
    - Added a requirements-side pinned feature map to
    `ConfigRequirementsToml`, threaded it through source-preserving
    requirements merge and normalization in `codex-config`, and made the
    TOML surface use `[features]` (while still accepting legacy
    `[feature_requirements]` for compatibility).
    - Exposed `featureRequirements` from `configRequirements/read`,
    regenerated the JSON/TypeScript schema artifacts, and updated the
    app-server README.
    - Wrapped the effective feature set in `ManagedFeatures`, backed by
    `ConstrainedWithSource<Features>`, and changed its API to mirror
    `Constrained<T>`: `can_set(...)`, `set(...) -> ConstraintResult<()>`,
    and result-returning `enable` / `disable` / `set_enabled` helpers.
    - Removed the legacy-usage and bulk-map passthroughs from
    `ManagedFeatures`; callers that need those behaviors now mutate a plain
    `Features` value and reapply it through `set(...)`, so the constrained
    wrapper remains the enforcement boundary.
    - Removed the production loophole for constructing unconstrained
    `ManagedFeatures`. Non-test code now creates it through the configured
    feature-loading path, and `impl From<Features> for ManagedFeatures` is
    restricted to `#[cfg(test)]`.
    - Rejected legacy feature aliases in enterprise feature requirements,
    and return a load error when a pinned combination cannot survive
    dependency normalization.
    - Validated config writes against enterprise feature requirements before
    persisting changes, including explicit conflicting writes and
    profile-specific feature states that normalize into invalid
    combinations.
    - Updated runtime and TUI feature-toggle paths to use the constrained
    setter API and to persist or apply the effective post-constraint value
    rather than the requested value.
    - Updated the `core_test_support` Bazel target to include the bundled
    core model-catalog fixtures in its runtime data, so helper code that
    resolves `core/models.json` through runfiles works in remote Bazel test
    environments.
    - Renamed the core config test coverage to emphasize that effective
    feature values are normalized at runtime, while conflicting persisted
    config writes are rejected.
    - Ran `compact_resume_after_second_compaction_preserves_history` inside
    an explicit 8 MiB test thread and Tokio runtime worker stack, following
    the existing larger-stack integration-test pattern, to keep the Windows
    `compact_resume_fork` test slice from aborting while a parallel
    investigation continues into whether some of the underlying async
    futures should be boxed.
    
    ## Verification
    
    - `cargo test -p codex-config`
    - `cargo test -p codex-core feature_requirements_ -- --nocapture`
    - `cargo test -p codex-core
    load_requirements_toml_produces_expected_constraints -- --nocapture`
    - `cargo test -p codex-core
    compact_resume_after_second_compaction_preserves_history -- --nocapture`
    - `cargo test -p codex-core compact_resume_fork -- --nocapture`
    - Re-ran the built `codex-core` `tests/all` binary with
    `RUST_MIN_STACK=262144` for
    `compact_resume_after_second_compaction_preserves_history` to confirm
    the explicit-stack harness fixes the deterministic low-stack repro.
    - `cargo test -p codex-core`
    - This still fails locally in unrelated integration areas that expect
    the `codex` / `test_stdio_server` binaries or hit existing `search_tool`
    wiremock mismatches.
    
    ## Docs
    
    `developers.openai.com/codex` should document the requirements-side
    `[features]` table for enterprise and MDM-managed configuration,
    including that it only accepts canonical feature keys and that
    conflicting config writes are rejected.
  • Make js_repl image output controllable (#13331)
    ## Summary
    
    Instead of always adding inner function call outputs to the model
    context, let js code decide which ones to return.
    
    - Stop auto-hoisting nested tool outputs from `codex.tool(...)` into the
    outer `js_repl` function output.
    - Keep `codex.tool(...)` return values unchanged as structured JS
    objects.
    - Add `codex.emitImage(...)` as the explicit path for attaching an image
    to the outer `js_repl` function output.
    - Support emitting from a direct image URL, a single `input_image` item,
    an explicit `{ bytes, mimeType }` object, or a raw tool response object
    containing exactly one image.
    - Preserve existing `view_image` original-resolution behavior when JS
    emits the raw `view_image` tool result.
    - Suppress the special `ViewImageToolCall` event for `js_repl`-sourced
    `view_image` calls so nested inspection stays side-effect free until JS
    explicitly emits.
    - Update the `js_repl` docs and generated project instructions with both
    recommended patterns:
      - `await codex.emitImage(codex.tool("view_image", { path }))`
    - `await codex.emitImage({ bytes: await page.screenshot({ type: "jpeg",
    quality: 85 }), mimeType: "image/jpeg" })`

  • Add under-development original-resolution view_image support (#13050)
    ## Summary
    
    Add original-resolution support for `view_image` behind the
    under-development `view_image_original_resolution` feature flag.
    
    When the flag is enabled and the target model is `gpt-5.3-codex` or
    newer, `view_image` now preserves original PNG/JPEG/WebP bytes and sends
    `detail: "original"` to the Responses API instead of using the legacy
    resize/compress path.
    
    ## What changed
    
    - Added `view_image_original_resolution` as an under-development feature
    flag.
    - Added `ImageDetail` to the protocol models and support for serializing
    `detail: "original"` on tool-returned images.
    - Added `PromptImageMode::Original` to `codex-utils-image`.
      - Preserves original PNG/JPEG/WebP bytes.
      - Keeps legacy behavior for the resize path.
    - Updated `view_image` to:
    - use the shared `local_image_content_items_with_label_number(...)`
    helper in both code paths
      - select original-resolution mode only when:
        - the feature flag is enabled, and
        - the model slug parses as `gpt-5.3-codex` or newer
    - Kept local user image attachments on the existing resize path; this
    change is specific to `view_image`.
    - Updated history/image accounting so only `detail: "original"` images
    use the docs-based GPT-5 image cost calculation; legacy images still use
    the old fixed estimate.
    - Added JS REPL guidance, gated on the same feature flag, to prefer JPEG
    at 85% quality unless lossless is required, while still allowing other
    formats when explicitly requested.
    - Updated tests and helper code that construct
    `FunctionCallOutputContentItem::InputImage` to carry the new `detail`
    field.
    
    ## Behavior
    
    ### Feature off
    - `view_image` keeps the existing resize/re-encode behavior.
    - History estimation keeps the existing fixed-cost heuristic.
    
    ### Feature on + `gpt-5.3-codex+`
    - `view_image` sends original-resolution images with `detail:
    "original"`.
    - PNG/JPEG/WebP source bytes are preserved when possible.
    - History estimation uses the GPT-5 docs-based image-cost calculation
    for those `detail: "original"` images.

  • Honor project_root_markers when discovering AGENTS.md (#12639)
    Fixes #12128
    
    The docs indicates that `project_root_markers` are used to discover the
    project root for local config as well as `AGENTS.md`. It looks like it
    was never wired up to support the latter.
    
    Summary
    - resolve project docs by walking to the configured
    `project_root_markers` (or defaults) instead of assuming the Git root,
    while honoring CLI overrides and handling malformed configs
    - fall back to the project’s canonical path chain and add a test that
    makes sure custom markers upstream of `.git` are respected
  • js_repl: remove codex.state helper references (#12275)
    ## Summary
    
    This PR removes `codex.state` from the `js_repl` helper surface and
    removes all corresponding documentation/instruction references.
    
    ## Motivation
    
    Top-level bindings in `js_repl` now persist across cells, so the extra
    `codex.state` helper is redundant and adds unnecessary API/docs surface.
    
    ## Changes
    
    - Removed the long-lived `state` object from the Node kernel helper
    wiring.
    - Stopped exposing `codex.state` (and `context.state`) during `js_repl`
    execution.
    - Updated user-facing `js_repl` docs to remove `codex.state`.
    - Updated generated instruction text and related test expectations to
    list only:
      - `codex.tmpDir`
      - `codex.tool(name, args?)`

  • Add js_repl host helpers and exec end events (#10672)
    ## Summary
    
    This PR adds host-integrated helper APIs for `js_repl` and updates model
    guidance so the agent can use them reliably.
    
    ### What’s included
    
    - Add `codex.tool(name, args?)` in the JS kernel so `js_repl` can call
    normal Codex tools.
    - Keep persistent JS state and scratch-path helpers available:
      - `codex.state`
      - `codex.tmpDir`
    - Wire `js_repl` tool calls through the standard tool router path.
    - Add/align `js_repl` execution completion/end event behavior with
    existing tool logging patterns.
    - Update dynamic prompt injection (`project_doc`) to document:
      - how to call `codex.tool(...)`
      - raw output behavior
    - image flow via `view_image` (`codex.tmpDir` +
    `codex.tool("view_image", ...)`)
    - stdio safety guidance (`console.log` / `codex.tool`, avoid direct
    `process.std*`)
    
    ## Why
    
    - Standardize JS-side tool usage on `codex.tool(...)`
    - Make `js_repl` behavior more consistent with existing tool execution
    and event/logging patterns.
    - Give the model enough runtime guidance to use `js_repl` safely and
    effectively.
    
    ## Testing
    
    - Added/updated unit and runtime tests for:
      - `codex.tool` calls from `js_repl` (including shell/MCP paths)
      - image handoff flow via `view_image`
      - prompt-injection text for `js_repl` guidance
      - execution/end event behavior and related regression coverage

  • fix: make project_doc skill-render tests deterministic (#11545)
    ## Why
    `project_doc::tests::skills_are_appended_to_project_doc` and
    `project_doc::tests::skills_render_without_project_doc` were assuming a
    single synthetic skill in test setup, but they called
    `load_skills(&cfg)`, which loads from repo/user/system roots.
    
    That made the assertions environment-dependent. After
    [#11531](https://github.com/openai/codex/pull/11531) added
    `.codex/skills/test-tui/SKILL.md`, the repo-scoped `test-tui` skill
    began appearing in these test outputs and exposed the flake.
    
    ## What Changed
    - Added a test-only helper in `codex-rs/core/src/project_doc.rs` that
    loads skills from an explicit root via `load_skills_from_roots`.
    - Scoped that root to `codex_home/skills` with `SkillScope::User`.
    - Updated both affected tests to use this helper instead of
    `load_skills(&cfg)`:
      - `skills_are_appended_to_project_doc`
      - `skills_render_without_project_doc`
    
    This keeps the tests focused on the fixture skills they create,
    independent of ambient repo/home skills.
    
    ## Verification
    - `cargo test -p codex-core
    project_doc::tests::skills_render_without_project_doc -- --exact`
    - `cargo test -p codex-core
    project_doc::tests::skills_are_appended_to_project_doc -- --exact`
  • Add feature-gated freeform js_repl core runtime (#10674)
    ## Summary
    
    This PR adds an **experimental, feature-gated `js_repl` core runtime**
    so models can execute JavaScript in a persistent REPL context across
    tool calls.
    
    The implementation integrates with existing feature gating, tool
    registration, prompt composition, config/schema docs, and tests.
    
    ## What changed
    
    - Added new experimental feature flag: `features.js_repl`.
    - Added freeform `js_repl` tool and companion `js_repl_reset` tool.
    - Gated tool availability behind `Feature::JsRepl`.
    - Added conditional prompt-section injection for JS REPL instructions
    via marker-based prompt processing.
    - Implemented JS REPL handlers, including freeform parsing and pragma
    support (timeout/reset controls).
    - Added runtime resolution order for Node:
      1. `CODEX_JS_REPL_NODE_PATH`
      2. `js_repl_node_path` in config
      3. `PATH`
    - Added JS runtime assets/version files and updated docs/schema.
    
    ## Why
    
    This enables richer agent workflows that require incremental JavaScript
    execution with preserved state, while keeping rollout safe behind an
    explicit feature flag.
    
    ## Testing
    
    Coverage includes:
    
    - Feature-flag gating behavior for tool exposure.
    - Freeform parser/pragma handling edge cases.
    - Runtime behavior (state persistence across calls and top-level `await`
    support).
    
    ## Usage
    
    ```toml
    [features]
    js_repl = true
    ```
    
    Optional runtime override:
    
    - `CODEX_JS_REPL_NODE_PATH`, or
    - `js_repl_node_path` in config.

  • [apps] Add gated instructions for Apps. (#10924)
    - [x] Add gated instructions for Apps.
  • Make skills prompt explicit about relative-path lookup (#10282)
    Fix cases where the model tries to locate skill scripts from the cwd and
    fails.
  • chore: improve skills render section (#8459)
    This change improves the skills render section
    - Separate the skills list from usage rules with clear subheadings
    - Define skill more clearly upfront
    - Remove confusing trigger/discovery wording and make reference-following guidance more actionable
  • chore: migrate from Config::load_from_base_config_with_overrides to ConfigBuilder (#8276)
    https://github.com/openai/codex/pull/8235 introduced `ConfigBuilder` and
    this PR updates all call non-test call sites to use it instead of
    `Config::load_from_base_config_with_overrides()`.
    
    This is important because `load_from_base_config_with_overrides()` uses
    an empty `ConfigRequirements`, which is a reasonable default for testing
    so the tests are not influenced by the settings on the host. This method
    is now guarded by `#[cfg(test)]` so it cannot be used by business logic.
    
    Because `ConfigBuilder::build()` is `async`, many of the test methods
    had to be migrated to be `async`, as well. On the bright side, this made
    it possible to eliminate a bunch of `block_on_future()` stuff.
  • Support SYSTEM skills. (#8220)
    1. Remove PUBLIC skills and introduce SYSTEM skills embedded in the
    binary and installed into $CODEX_HOME/skills/.system at startup.
    2. Skills are now always enabled (feature flag removed).
    3. Update skills/list to accept forceReload and plumb it through (not
    used by clients yet).
  • Add public skills + improve repo skill discovery and error UX (#8098)
    1. Adds SkillScope::Public end-to-end (core + protocol) and loads skills
    from the public cache directory
    2. Improves repo skill discovery by searching upward for the nearest
    .codex/skills within a git repo
    3. Deduplicates skills by name with deterministic ordering to avoid
    duplicates across sources
    4. Fixes garbled “Skill errors” overlay rendering by preventing pending
    history lines from being injected during the modal
    5. Updates the project docs “Skills” intro wording to avoid hardcoded
    paths
  • Inject SKILL.md when it's explicitly mentioned. (#7763)
    1. Skills load once in core at session start; the cached outcome is
    reused across core and surfaced to TUI via SessionConfigured.
    2. TUI detects explicit skill selections, and core injects the matching
    SKILL.md content into the turn when a selected skill is present.
  • feat: Support listing and selecting skills via $ or /skills (#7506)
    List/Select skills with $-mention or /skills
  • feat: experimental support for skills.md (#7412)
    This change prototypes support for Skills with the CLI. This is an
    **experimental** feature for internal testing.

  • Fall back to configured instruction files if AGENTS.md isn't available (#4544)
    Allow users to configure an agents.md alternative to consume, but warn
    the user it may degrade model performance.
    
    Fixes #4376
  • chore: enable clippy::redundant_clone (#3489)
    Created this PR by:
    
    - adding `redundant_clone` to `[workspace.lints.clippy]` in
    `cargo-rs/Cargol.toml`
    - running `cargo clippy --tests --fix`
    - running `just fmt`
    
    Though I had to clean up one instance of the following that resulted:
    
    ```rust
    let codex = codex;
    ```
  • read all AGENTS.md up to git root (#2532)
    This updates our logic for AGENTS.md to match documented behavior, which
    is to read all AGENTS.md files from cwd up to git root.
  • Added allow-expect-in-tests / allow-unwrap-in-tests (#2328)
    This PR:
    * Added the clippy.toml to configure allowable expect / unwrap usage in
    tests
    * Removed as many expect/allow lines as possible from tests
    * moved a bunch of allows to expects where possible
    
    Note: in integration tests, non `#[test]` helper functions are not
    covered by this so we had to leave a few lingering `expect(expect_used`
    checks around
  • Add support for custom base instructions (#1645)
    Allows providing custom instructions file as a config parameter and
    custom instruction text via MCP tool call.
  • fix: always send full instructions when using the Responses API (#1207)
    This fixes a longstanding error in the Rust CLI where `codex.rs`
    contained an errant `is_first_turn` check that would exclude the user
    instructions for subsequent "turns" of a conversation when using the
    responses API (i.e., when `previous_response_id` existed).
    
    While here, renames `Prompt.instructions` to `Prompt.user_instructions`
    since we now have quite a few levels of instructions floating around.
    Also removed an unnecessary use of `clone()` in
    `Prompt.get_full_instructions()`.
  • Disallow expect via lints (#865)
    Adds `expect()` as a denied lint. Same deal applies with `unwrap()`
    where we now need to put `#[expect(...` on ones that we legit want. Took
    care to enable `expect()` in test contexts.
    
    # Tests
    
    ```
    cargo fmt
    cargo clippy --all-features --all-targets --no-deps -- -D warnings
    cargo test
    ```
  • feat: add support for AGENTS.md in Rust CLI (#885)
    The TypeScript CLI already has support for including the contents of
    `AGENTS.md` in the instructions sent with the first turn of a
    conversation. This PR brings this functionality to the Rust CLI.
    
    To be considered, `AGENTS.md` must be in the `cwd` of the session, or in
    one of the parent folders up to a Git/filesystem root (whichever is
    encountered first).
    
    By default, a maximum of 32 KiB of `AGENTS.md` will be included, though
    this is configurable using the new-in-this-PR `project_doc_max_bytes`
    option in `config.toml`.
