• feat: if .codex is a sub-folder of a writable root, then make it read-only to the sandbox (#8088)

  In preparation for in-repo configuration support, this updates
  `WritableRoot::get_writable_roots_with_cwd()` to include the `.codex`
  subfolder in `WritableRoot.read_only_subpaths`, if it exists, as we
  already do for `.git`.
  
  As noted, currently, like `.git`, `.codex` will only be read-only under
  macOS Seatbelt, but we plan to bring support to other OSes, as well.
  
  Updated the integration test in `seatbelt.rs` so that it actually
  attempts to run the generated Seatbelt commands, verifying that:
  
  - trying to write to `.codex/config.toml` in a writable root fails
  - trying to write to `.git/hooks/pre-commit` in a writable root fails
  - trying to write to the writable root containing the `.codex` and
  `.git` subfolders succeeds

• docs: document enabling experimental skills (#8024)

  ## Notes
  
  Skills are behind the experimental `skills` feature flag (disabled by
  default), but the skills guide didn't explain how to turn them on.
  
  - Add an explicit enable section to `docs/skills.md` (config +
  `--enable`)
  - Add the skills flag to `docs/config.md` and `docs/example-config.md`
  - Document the `/skills` slash command

  ## Changes
  - Update config docs and example config comments to state that "xhigh"
  is supported on gpt-5.2 as well as gpt-5.1-codex-max
  - Adjust the FAQ model-support section to reflect broader xhigh
  availability

• fix: policy/*.codexpolicy -> rules/*.rules (#7888)

  We decided that `*.rules` is a more fitting (and concise) file extension
  than `*.codexpolicy`, so we are changing the file extension for the
  "execpolicy" effort. We are also changing the subfolder of `$CODEX_HOME`
  from `policy` to `rules` to match.
  
  This PR updates the in-repo docs and we will update the public docs once
  the next CLI release goes out.
  
  Locally, I created `~/.codex/rules/default.rules` with the following
  contents:
  
  ```
  prefix_rule(pattern=["gh", "pr", "view"])
  ```
  
  And then I asked Codex to run:
  
  ```
  gh pr view 7888 --json title,body,comments
  ```
  
  and it was able to!

• feat(tui2): add feature-flagged tui2 frontend (#7793)

  Introduce a new codex-tui2 crate that re-exports the existing
  interactive TUI surface and delegates run_main directly to codex-tui.
  This keeps behavior identical while giving tui2 its own crate for future
  viewport work.
  
  Wire the codex CLI to select the frontend via the tui2 feature flag.
  When the merged CLI overrides include features.tui2=true (e.g. via
  --enable tui2), interactive runs are routed through
  codex_tui2::run_main; otherwise they continue to use the original
  codex_tui::run_main.
  
  Register Feature::Tui2 in the core feature registry and add the tui2
  crate and dependency entries so the new frontend builds alongside the
  existing TUI.
  
  This is a stub that only wires up the feature flag for this.

• fix: refine the warning message and docs for deprecated tools config (#7685)

  Issue #7661 revealed that users are confused by deprecation warnings
  like:
  > `tools.web_search` is deprecated. Use `web_search_request` instead.
  
  This message misleadingly suggests renaming the config key from
  `web_search` to `web_search_request`, when the actual required change is
  to **move and rename the configuration from the `[tools]` section to the
  `[features]` section**.
  
  This PR clarifies the warning messages and documentation to make it
  clear that deprecated `[tools]` configurations should be moved to
  `[features]`. Changes made:
  - Updated deprecation warning format in `codex-rs/core/src/codex.rs:520`
  to include `[features].` prefix
  - Updated corresponding test expectations in
  `codex-rs/core/tests/suite/deprecation_notice.rs:39`
  - Improved documentation in `docs/config.md` to clarify upfront that
  `[tools]` options are deprecated in favor of `[features]`

• fix(doc): TOML otel exporter example — multi-line inline table is inv… (#7669)

  …alid (#7668)
  
  The `otel` exporter example in `docs/config.md` is misleading and will
  cause
  the configuration parser to fail if copied verbatim.
  
  Summary
  -------
  The example uses a TOML inline table but spreads the inline-table braces
  across multiple lines. TOML inline tables must be contained on a single
  line
  (`key = { a = 1, b = 2 }`); placing newlines inside the braces triggers
  a
  parse error in most TOML parsers and prevents Codex from starting.
  
  Reproduction
  ------------
  1. Paste the snippet below into `~/.codex/config.toml` (or your project
  config).
  2. Run `codex` (or the command that loads the config).
  3. The process will fail to start with a TOML parse error similar to:
  
  ```text
  Error loading config.toml: TOML parse error at line 55, column 27
     |
  55 | exporter = { otlp-http = {
     |                           ^
  newlines are unsupported in inline tables, expected nothing
  ```
  
  Problematic snippet (as currently shown in the docs)
  ---------------------------------------------------
  ```toml
  [otel]
  exporter = { otlp-http = {
    endpoint = "https://otel.example.com/v1/logs",
    protocol = "binary",
    headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" }
  }}
  ```
  
  Recommended fixes
  ------------------
  ```toml
  [otel.exporter."otlp-http"]
  endpoint = "https://otel.example.com/v1/logs"
  protocol = "binary"
  
  [otel.exporter."otlp-http".headers]
  "x-otlp-api-key" = "${OTLP_TOKEN}"
  ```
  
  Or, keep an inline table but write it on one line (valid but less
  readable):
  
  ```toml
  [otel]
  exporter = { "otlp-http" = { endpoint = "https://otel.example.com/v1/logs", protocol = "binary", headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" } } }
  ```

• Refactor execpolicy fallback evaluation (#7544)

  ## Refactor of the `execpolicy` crate
  
  To illustrate why we need this refactor, consider an agent attempting to
  run `apple | rm -rf ./`. Suppose `apple` is allowed by `execpolicy`.
  Before this PR, `execpolicy` would consider `apple` and `pear` and only
  render one rule match: `Allow`. We would skip any heuristics checks on
  `rm -rf ./` and immediately approve `apple | rm -rf ./` to run.
  
  To fix this, we now thread a `fallback` evaluation function into
  `execpolicy` that runs when no `execpolicy` rules match a given command.
  In our example, we would run `fallback` on `rm -rf ./` and prevent
  `apple | rm -rf ./` from being run without approval.

  back to disk under the same lock to keep writers safe.

  ## Changes
  
  * `docs/config.md`
  
  * Add `xhigh` to the official list of reasoning levels with a note that
  `xhigh` is exclusive to Codex Max.
  
  * `docs/example-config.md`
  
  * Update the example comment adding `xhigh` as a valid option but only
  for Codex Max.
  
  * `docs/faq.md`
  
    * Update the model recommendation to `GPT-5.1 Codex Max`.
  * Mention that users can choose `high` or the newly documented `xhigh`
  level when using Codex Max.

• doc: fix relative links and add tips (#7319)

  This PR is a documentation only one which:
  - addresses the #7231 by adding a paragraph in `docs/getting-started.md`
  in the tips category to encourage users to load everything needed in
  their environment
  - corrects link referencing in `docs/platform-sandboxing.md` so that the
  page link opens at the right section
  - removes the explicit heading IDs like {#my-id} in `docs/advanced.md`
  which are not supported by GitHub and are **not** rendered in the UI:

  to work in this branch (you can test by going to

  - the MCP link goes straight to the correct section now:

• Added feature switch to disable animations in TUI (#6870)

  This PR adds support for a new feature flag `tui.animations`. By
  default, the TUI uses animations in its welcome screen, "working"
  spinners, and "shimmer" effects. This animations can interfere with
  screen readers, so it's good to provide a way to disable them.
  
  This change is inspired by [a
  PR](https://github.com/openai/codex/pull/4014) contributed by @Orinks.
  That PR has faltered a bit, but I think the core idea is sound. This
  version incorporates feedback from @aibrahim-oai. In particular:
  1. It uses a feature flag (`tui.animations`) rather than the unqualified
  CLI key `no-animations`. Feature flags are the preferred way to expose
  boolean switches. They are also exposed via CLI command switches.
  2. It includes more complete documentation.
  3. It disables a few animations that the other PR omitted.

• LM Studio OSS Support (#2312)

  ## Overview
  
  Adds LM Studio OSS support. Closes #1883
  
  
  ### Changes
  This PR enhances the behavior of `--oss` flag to support LM Studio as a
  provider. Additionally, it introduces a new flag`--local-provider` which
  can take in `lmstudio` or `ollama` as values if the user wants to
  explicitly choose which one to use.
  
  If no provider is specified `codex --oss` will auto-select the provider
  based on whichever is running.
  
  #### Additional enhancements 
  The default can be set using `oss-provider` in config like:
  
  ```
  oss_provider = "lmstudio"
  ```
  
  For non-interactive users, they will need to either provide the provider
  as an arg or have it in their `config.toml`
  
  ### Notes
  For best performance, [set the default context
  length](https://lmstudio.ai/docs/app/advanced/per-model) for gpt-oss to
  the maximum your machine can support

     - Example 1: Basic named arguments with TICKET_ID and TICKET_TITLE
     - Example 2: Mixed positional and named arguments with FILE and FOCUS
     - Example 3: Using positional arguments
  - Example 4: Updated draftpr example to use proper $FEATURE_NAME syntax
     - Added clear usage examples showing KEY=value syntax
     - Added expanded prompt examples showing the result
     - Documented error handling and validation requirements
  
  3. **Added Implementation Reference section** that references the
  relevant feature implementation from the codebase (PRs #4470 and #4474
  for initial implementation, #5332 and #5403 for clarifications).
  
  This addresses issue #5039 by providing complete, accurate documentation
  for named argument usage in custom prompts.

• Enable TUI notifications by default (#6633)

  ## Summary
  - default the `tui.notifications` setting to enabled so desktop
  notifications work out of the box
  - update configuration tests and documentation to reflect the new
  default
  
  ## Testing
  - `cargo test -p codex-core` *(fails:
  `exec::tests::kill_child_process_group_kills_grandchildren_on_timeout`
  is flaky in this sandbox because the spawned grandchild process stays
  alive)*
  - `cargo test -p codex-core
  exec::tests::kill_child_process_group_kills_grandchildren_on_timeout`
  *(fails: same sandbox limitation as above)*

• Add opt-out for rate limit model nudge (#6433)

  ## Summary
  - add a `hide_rate_limit_model_nudge` notice flag plus config edit
  plumbing so the rate limit reminder preference is persisted and
  documented
  - extend the chat widget prompt with a "never show again" option, and
  wire new app events so selecting it hides future nudges immediately and
  writes the config
  - add unit coverage and refresh the snapshot for the three-option prompt
  
  ## Testing
  - `just fmt`
  - `just fix -p codex-tui`
  - `just fix -p codex-core`
  - `cargo test -p codex-tui`
  - `cargo test -p codex-core` *(fails at
  `exec::tests::kill_child_process_group_kills_grandchildren_on_timeout`:
  grandchild process still alive)*
