• Better handling skill depdenencies on ENV VAR. (#9017)

  An experimental flow for env var skill dependencies. Skills can now
  declare required env vars in SKILL.md; if missing, the CLI prompts the
  user to get the value, and Core will store it in memory (eventually to a
  local persistent store)

• chore: deprecate old web search feature flags (#10097)

  deprecate all old web search flags and aliases, including:
  - `[features].web_search_request` and `[features].web_search_cached`
  - `[tools].web_search`
  - `[features].web_search`
  
  slightly rework `legacy_usages` to enable pointing to non-features from
  deprecated features; we need to point to `web_search` (not under
  `[features]`) from things like `[features].web_search_cached` and
  `[features].web_search_request`.
  
  Added integration tests to confirm deprecation notice is shown on
  explicit enablement and disablement of deprecated flags.

• 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

• Aligned feature stage names with public feature maturity stages (#9929)

  We've recently standardized a [feature maturity
  model](https://developers.openai.com/codex/feature-maturity) that we're
  using in our docs and support forums to communicate expectations to
  users. This PR updates the internal stage names and descriptions to
  match.
  
  This change involves a simple internal rename and updates to a few
  user-visible strings. No functional change.

• [connectors] Support connectors part 1 - App server & MCP (#9667)

  In order to make Codex work with connectors, we add a built-in gateway
  MCP that acts as a transparent proxy between the client and the
  connectors. The gateway MCP collects actions that are accessible to the
  user and sends them down to the user, when a connector action is chosen
  to be called, the client invokes the action through the gateway MCP as
  well.
  
   - [x] Add the system built-in gateway MCP to list and run connectors.
   - [x] Add the app server methods and protocol

• feat(tui): retire the tui2 experiment (#9640)

  ## Summary
  - Retire the experimental TUI2 implementation and its feature flag.
  - Remove TUI2-only config/schema/docs so the CLI stays on the
  terminal-native path.
  - Keep docs aligned with the legacy TUI while we focus on redraw-based
  improvements.
  
  ## Customer impact
  - Retires the TUI2 experiment and keeps Codex on the proven
  terminal-native UI while we invest in redraw-based improvements to the
  existing experience.
  
  ## Migration / compatibility
  - If you previously set tui2-related options in config.toml, they are
  now ignored and Codex continues using the existing terminal-native TUI
  (no action required).
  
  ## Context
  - What worked: a transcript-owned viewport delivered excellent resize
  rewrap and high-fidelity copy (especially for code).
  - Why stop: making that experience feel fully native across the
  environment matrix (terminal emulator, OS, input modality, multiplexer,
  font/theme, alt-screen behavior) creates a combinatorial explosion of
  edge cases.
  - What next: we are focusing on redraw-based improvements to the
  existing terminal-native TUI so scrolling, selection, and copy remain
  native while resize/redraw correctness improves.
  
  ## Testing
  - just write-config-schema
  - just fmt

• add generated jsonschema for config.toml (#8956)

  ### What
  Add JSON Schema generation for `config.toml`, with checked‑in
  `docs/config.schema.json`. We can move the schema elsewhere if preferred
  (and host it if there's demand).
  
  Add fixture test to prevent drift and `just write-config-schema` to
  regenerate on schema changes.
  
  Generate MCP config schema from `RawMcpServerConfig` instead of
  `McpServerConfig` because that is the runtime type used for
  deserialization.
  
  Populate feature flag values into generated schema so they can be
  autocompleted.
  
  ### Tests
  Added tests + regenerate script to prevent drift. Tested autocompletions
  using generated jsonschema locally with Even Better TOML.

• Add feature for optional request compression (#8767)

  Adds a new feature
  `enable_request_compression` that will compress using zstd requests to
  the codex-backend. Currently only enabled for codex-backend so only enabled for openai providers when using chatgpt::auth even when the feature is enabled
  
  Added a new info log line too for evaluating the compression ratio and
  overhead off compressing before requesting. You can enable with
  `RUST_LOG=$RUST_LOG,codex_client::transport=info`
  
  ```
  2026-01-06T00:09:48.272113Z  INFO codex_client::transport: Compressed request body with zstd pre_compression_bytes=28914 post_compression_bytes=11485 compression_duration_ms=0

  Add `web_search_cached` feature to config. Enables `web_search` tool
  with access only to cached/indexed results (see
  [docs](https://platform.openai.com/docs/guides/tools-web-search#live-internet-access)).
  
  This takes precedence over the existing `web_search_request`, which
  continues to enable `web_search` over live results as it did before.
  
  `web_search_cached` is disabled for review mode, as `web_search_request`
  is.

• feat: support in-repo .codex/config.toml entries as sources of config info (#8354)

  - We now support `.codex/config.toml` in repo (from `cwd` up to the
  first `.git` found, if any) as layers in `ConfigLayerStack`. A new
  `ConfigLayerSource::Project` variant was added to support this.
  - In doing this work, I realized that we were resolving relative paths
  in `config.toml` after merging everything into one `toml::Value`, which
  is wrong: paths should be relativized with respect to the folder
  containing the `config.toml` that was deserialized. This PR introduces a
  deserialize/re-serialize strategy to account for this in
  `resolve_config_paths()`. (This is why `Serialize` is added to so many
  types as part of this PR.)
  - Added tests to verify this new behavior.

• feat(windows) start powershell in utf-8 mode (#7902)

  ## Summary
  Adds a FeatureFlag to enforce UTF8 encoding in powershell, particularly
  Windows Powershell v5. This should help address issues like #7290.
  
  Notably, this PR does not include the ability to parse `apply_patch`
  invocations within UTF8 shell commands (calls to the freeform tool
  should not be impacted). I am leaving this out of scope for now. We
  should address before this feature becomes Stable, but those cases are
  not the default behavior at this time so we're okay for experimentation
  phase. We should continue cleaning up the `apply_patch::invocation`
  logic and then can handle it more cleanly.
  
  ## Testing
  - [x] Adds additional testing
