followup to https://github.com/openai/codex/pull/13212 to expose fast
tier controls to app server
(majority of this PR is generated schema jsons - actual code is +69 /
-35 and +24 tests )
- add service tier fields to the app-server protocol surfaces used by
thread lifecycle, turn start, config, and session configured events
- thread service tier through the app-server message processor and core
thread config snapshots
- allow runtime config overrides to carry service tier for app-server
callers
cleanup:
- Removing useless "legacy" code supporting "standard" - we moved to
None | "fast", so "standard" is not needed.
Closes#3493
## Problem
When a user's home directory (or any ancestor) contains a broad
`.gitignore` (e.g. `*` + `!.gitignore`), the `@` file mention picker in
Codex silently hides valid repository files like `package.json`. The
picker returns `no matches` for searches that should succeed. This is
surprising because manually typed paths still work, making the failure
hard to diagnose.
## Mental model
Git itself never walks above the repository root to assemble its ignore
list. Its `.gitignore` resolution is strictly scoped: it reads
`.gitignore` files from the repo root downward, the per-repo
`.git/info/exclude`, and the user's global excludes file (via
`core.excludesFile`). A `.gitignore` sitting in a parent directory above
the repo root has no effect on `git status`, `git ls-files`, or any
other git operation. Our file search should replicate this contract
exactly.
The `ignore` crate's `WalkBuilder` has a `require_git` flag that
controls whether it follows this contract:
- `require_git(false)` (the previous setting): the walker reads
`.gitignore` files from _all_ ancestor directories, even those above or
outside the repository root. This is a deliberate divergence from git's
behavior in the `ignore` crate, intended for non-git use cases. It means
a `~/.gitignore` with `*` will suppress every file in the walk—something
git itself would never do.
- `require_git(true)` (this fix): the walker only applies `.gitignore`
semantics when it detects a `.git` directory, scoping ignore resolution
to the repository boundary. This matches git's own behavior: parent
`.gitignore` files above the repo root have no effect.
The fix is a one-line change: `require_git(false)` becomes
`require_git(true)`.
## How `require_git(false)` got here
The setting was introduced in af338cc (#2981, "Improve @ file search:
include specific hidden dirs such as .github, .gitlab"). That PR's goal
was to make hidden directories like `.github` and `.vscode` discoverable
by setting `.hidden(false)` on the walker. The `require_git(false)` was
added alongside it with the comment _"Don't require git to be present to
apply git-related ignore rules"_—the author likely intended gitignore
rules to still filter results even when no `.git` directory exists (e.g.
searching an extracted tarball that has a `.gitignore` but no `.git`).
The unintended consequence: with `require_git(false)`, the `ignore`
crate walks _above_ the search root to find `.gitignore` files in
ancestor directories. This is a side effect the original author almost
certainly didn't anticipate. The PR message says "Preserve `.gitignore`
semantics," but `require_git(false)` actually _breaks_ git's semantics
by applying ancestor ignore files that git itself would never read.
In short: the intent was "apply gitignore even without `.git`" but the
effect was "apply gitignore from every ancestor directory." This fix
restores git-correct scoping.
## Non-goals
- This PR does not change behavior when `respect_gitignore` is `false`
(that path already disables all git-related ignore rules).
- The first test
(`parent_gitignore_outside_repo_does_not_hide_repo_files`) intentionally
omits `git init`. The `ignore` crate's `require_git(true)` causes it to
skip gitignore processing entirely when no `.git` exists, which is the
desired behavior for that scenario. A second test
(`git_repo_still_respects_local_gitignore_when_enabled`) covers the
complementary case with a real git repo.
## Tradeoffs
**Behavioral shift**: With `require_git(true)`, directories that contain
`.gitignore` files but are _not_ inside a git repository will no longer
have those ignore rules applied during `@` search. This is a correctness
improvement for the primary use case (searching inside repos), but
changes behavior for the edge case of searching non-repo directories
that happen to have `.gitignore` files. In practice, Codex is
overwhelmingly used inside git repositories, so this tradeoff strongly
favors the fix.
**Two test strategies**: The first test omits `git init` to verify
parent ignore leakage is blocked; the second runs `git init` to verify
the repo's own `.gitignore` is still honored. Together they cover both
sides of the `require_git(true)` contract.
## Architecture
The change is in `walker_worker()` within
`codex-rs/file-search/src/lib.rs`, which configures the
`ignore::WalkBuilder` used by the file search walker thread. The walker
feeds discovered file paths into `nucleo` for fuzzy matching. The
`require_git` flag controls whether the walker consults `.gitignore`
files at all—it sits upstream of all ignore processing.
```
walker_worker
└─ WalkBuilder::new(root)
├─ .hidden(false) — include dotfiles
├─ .follow_links(true) — follow symlinks
├─ .require_git(true) — ← THE FIX: only apply gitignore in git repos
└─ (conditional) git_ignore(false), git_global(false), etc.
└─ applied when respect_gitignore == false
```
## Tests
- `parent_gitignore_outside_repo_does_not_hide_repo_files`: creates a
temp directory tree with a parent `.gitignore` containing `*`, a child
"repo" directory with `package.json` and `.vscode/settings.json`, and
asserts that both files are discoverable via `run()` with
`respect_gitignore: true`.
- `git_repo_still_respects_local_gitignore_when_enabled`: the
complementary test—runs `git init` inside the child directory and
verifies that the repo's own `.gitignore` exclusions still work (e.g.
`.vscode/extensions.json` is excluded while `.vscode/settings.json` is
whitelisted). Confirms that `require_git(true)` does not disable
gitignore processing inside actual git repositories.
- add a local Fast mode setting in codex-core (similar to how model id
is currently stored on disk locally)
- send `service_tier=priority` on requests when Fast is enabled
- add `/fast` in the TUI and persist it locally
- feature flag
## Problem
Before this change, composer paths that cleared the textarea after
submit or slash-command dispatch
also cleared the textarea kill buffer. That meant a user could `Ctrl+K`
part of a draft, trigger a
composer action that cleared the visible draft, and then lose the
ability to `Ctrl+Y` the killed
text back.
This was especially awkward for workflows where the user wants to
temporarily remove text, run a
composer action such as changing reasoning level or dispatching a slash
command, and then restore
the killed text into the now-empty draft.
## Mental model
This change separates visible draft state from editing-history state.
The visible draft includes the current textarea contents and text
elements that should be cleared
when the composer submits or dispatches a command. The kill buffer is
different: it represents the
most recent killed text and should survive those composer-driven clears
so the user can still yank
it back afterward.
After this change, submit and slash-command dispatch still clear the
visible textarea contents, but
they no longer erase the most recent kill.
## Non-goals
This does not implement a multi-entry kill ring or change the semantics
of `Ctrl+K` and `Ctrl+Y`
beyond preserving the existing yank target across these clears.
It also does not change how submit, slash-command parsing, prompt
expansion, or attachment handling
work, except that those flows no longer discard the textarea kill buffer
as a side effect of
clearing the draft.
## Tradeoffs
The main tradeoff is that clearing the visible textarea is no longer
equivalent to fully resetting
all editing state. That is intentional here, because submit and
slash-command dispatch are composer
actions, not requests to forget the user's most recent kill.
The benefit is better editing continuity. The cost is that callers must
understand that full-buffer
replacement resets visible draft state but not the kill buffer.
## Architecture
The behavioral change is in `TextArea`: full-buffer replacement now
rebuilds text and elements
without clearing `kill_buffer`.
`ChatComposer` already clears the textarea after successful submit and
slash-command dispatch by
calling into those textarea replacement paths. With this change, those
existing composer flows
inherit the new behavior automatically: the visible draft is cleared,
but the last killed text
remains available for `Ctrl+Y`.
The tests cover both layers:
- `TextArea` verifies that the kill buffer survives full-buffer
replacement.
- `ChatComposer` verifies that it survives submit.
- `ChatComposer` also verifies that it survives slash-command dispatch.
## Observability
There is no dedicated logging for kill-buffer preservation. The most
direct way to reason about the
behavior is to inspect textarea-wide replacement paths and confirm
whether they treat the kill
buffer as visible-buffer state or as editing-history state.
If this regresses in the future, the likely failure mode is simple and
user-visible: `Ctrl+Y` stops
restoring text after submit or slash-command clears even though ordinary
kill/yank still works
within a single uninterrupted draft.
## Tests
Added focused regression coverage for the new contract:
- `kill_buffer_persists_across_set_text`
- `kill_buffer_persists_after_submit`
- `kill_buffer_persists_after_slash_command_dispatch`
Local verification:
- `just fmt`
- `cargo test -p codex-tui`

## Summary
This change removes the compiled permissions field from skill metadata
and keeps permission_profile as the single source of truth.
Skill loading no longer compiles skill permissions eagerly. Instead, the
zsh-fork skill escalation path compiles `skill.permission_profile` when
it needs to determine the sandbox to apply for a skill script.
## Behavior change
For skills that declare:
```
permissions: {}
```
we now treat that the same as having no skill permissions override,
instead of creating and using a default readonly sandbox. This change
makes the behavior more intuitive:
- only non-empty skill permission profiles affect sandboxing
- omitting permissions and writing permissions: {} now mean the same
thing
- skill metadata keeps a single permissions representation instead of
storing derived state too
Overall, this makes skill sandbox behavior easier to understand and more
predictable.
Currently we emit `thread/status/changed` with `Idle` status right
before sending `thread/started` event (which also has `Idle` status in
it).
It feels that there is no point in that as client has no way to know
prior state of the thread as it didn't exist yet, so silence these kinds
of notifications.
This is a follow-up for https://github.com/openai/codex/pull/13047
## Why
We had a race where `turn/started` could be observed before the thread
had actually transitioned to `Active`. This was because we eagerly
emitted `turn/started` in the request handler for `turn/start` (and
`review/start`).
That was showing up as flaky `thread/resume` tests, but the real issue
was broader: a client could see `turn/started` and still get back an
idle thread immediately afterward.
The first idea was to eagerly call
`thread_watch_manager.note_turn_started(...)` from the `turn/start`
request path. That turns out to be unsafe, because
`submit(Op::UserInput)` only queues work. If a turn starts and completes
quickly, request-path bookkeeping can race with the real lifecycle
events and leave stale running state behind.
**The real fix** is to move `turn/started` to emit only after the turn
_actually_ starts, so we do that by waiting for the
`EventMsg::TurnStarted` notification emitted by codex core. We do this
for both `turn/start` and `review/start`.
I also verified this change is safe for our first-party codex apps -
they don't have any assumptions that `turn/started` is emitted before
the RPC response to `turn/start` (which is correct anyway).
I also removed `single_client_mode` since it isn't really necessary now.
## Testing
- `cargo test -p codex-app-server thread_resume -- --nocapture`
- `cargo test -p codex-app-server
'suite::v2::turn_start::turn_start_emits_notifications_and_accepts_model_override'
-- --exact --nocapture`
- `cargo test -p codex-app-server`
- migrate the realtime websocket transport to the new session and
handoff flow
- make the realtime model configurable in config.toml and use API-key
auth for the websocket

### Overview
This PR adds the first piece of tracing for app-server JSON-RPC
requests.
There are two main changes:
- JSON-RPC requests can now take an optional W3C trace context at the
top level via a `trace` field (`traceparent` / `tracestate`).
- app-server now creates a dedicated request span for every inbound
JSON-RPC request in `MessageProcessor`, and uses the request-level trace
context as the parent when present.
For compatibility with existing flows, app-server still falls back to
the TRACEPARENT env var when there is no request-level traceparent.
This PR is intentionally scoped to the app-server boundary. In a
followup, we'll actually propagate trace context through the async
handoff into core execution spans like run_turn, which will make
app-server traces much more useful.
### Spans
A few details on the app-server span shape:
- each inbound request gets its own server span
- span/resource names are based on the JSON-RPC method (`initialize`,
`thread/start`, `turn/start`, etc.)
- spans record transport (stdio vs websocket), request id, connection
id, and client name/version when available
- `initialize` stores client metadata in session state so later requests
on the same connection can reuse it
Currently `thread/name/set` does only work for loaded threads.
Expand the scope to also support persisted but not-yet-loaded ones for a
more predictable API surface.
This will make it possible to rename threads discovered via
`thread/list` and similar operations.
## Summary
- increase `DEFAULT_READ_TIMEOUT` in `codex_message_processor_flow` from
20s to 45s
- keep test behavior the same while avoiding platform timing flakes
## Why
Windows ARM64 CI showed these tests taking about 24s before
`task_complete`, which could fail early and produce wiremock
request-count mismatches.
## Testing
- just fmt
- cargo test -p codex-app-server codex_message_processor_flow --
--nocapture
## Summary
Codex discovered this one - shell_snapshot tests were breaking on my
machine because I had a multiline env var. We should handle these!
## Testing
- [x] existing tests pass
- [x] Updated unit tests
## Summary
- restore `Tab to queue` when a draft is present and the agent is
running
- keep draft-idle footers passive by showing the normal footer or status
line instead of `? for shortcuts`
- align footer snapshot coverage with the updated draft footer behavior

Historically, we cloned the Bash repo from
https://github.com/bminor/bash, but for whatever reason, it was removed
at some point.
I had a local clone of it, so I pushed it to
https://github.com/bolinfest/bash so that we could continue running our
CI job. I did this in https://github.com/openai/codex/pull/9563, and as
you can see, I did not tamper with the commit hash we used as the basis
of this build.
Using a personal fork is not great, so this PR changes the CI job to use
what appears to be considered the source of truth for Bash, which is
https://git.savannah.gnu.org/git/bash.git.
Though in testing this out, it appears this Git server does not support
the combination of `git clone --depth 1
https://git.savannah.gnu.org/git/bash` and `git fetch --depth 1 origin
a8a1c2fac029404d3f42cd39f5a20f24b6e4fe4b`, as it fails with the
following error:
```
error: Server does not allow request for unadvertised object a8a1c2fac029404d3f42cd39f5a20f24b6e4fe4b
```
so unfortunately this means that we have to do a full clone instead of a
shallow clone in our CI jobs, which will be a bit slower.
Also updated `codex-rs/shell-escalation/README.md` to reflect this
change.
## Summary
- reuse the parent shell snapshot when spawning/forking/resuming
`SessionSource::SubAgent(SubAgentSource::ThreadSpawn { .. })` sessions
- plumb inherited snapshot through `AgentControl -> ThreadManager ->
Codex::spawn -> SessionConfiguration`
- skip shell snapshot refresh on cwd updates for thread-spawn subagents
so inherited snapshots are not replaced
## Why
- avoids per-subagent shell snapshot creation and cleanup work
- keeps thread-spawn subagents on the parent snapshot path, matching the
intended parent/child snapshot model
## Validation
- `just fmt` (in `codex-rs`)
- `cargo test -p codex-core --no-run`
- `cargo test -p codex-core spawn_agent -- --nocapture`
- `cargo test -p codex-core --test all
suite::agent_jobs::spawn_agents_on_csv_runs_and_exports`
## Notes
- full `cargo test -p codex-core --test all` was left running separately
for broader verification

This change fixes a Codex app account-state sync bug where clients could
know the user was signed in but still miss the ChatGPT subscription
tier, which could lead to incorrect upgrade messaging for paid users.
The root cause was that `account/updated` only carried `authMode` while
plan information was available separately via `account/read` and
rate-limit snapshots, so this update adds `planType` to
`account/updated`, populates it consistently across login and refresh
paths.
…with launchservicesd
Add mach lookup for `launchservicesd` when extending the sandbox for
`MacOSAutomationPermission::BundleIDs`. This is necessary so that the
target application can be launched for automation.
This omission was due to a spec error in a document, which has been
fixed.
Support loading plugins.
Plugins can now be enabled via [plugins.<name>] in config.toml. They are
loaded as first-class entities through PluginsManager, and their default
skills/ and .mcp.json contributions are integrated into the existing
skills and MCP flows.
## Why
[#12964](https://github.com/openai/codex/pull/12964) added
`host_executable()` support to `codex-execpolicy`, and
[#13046](https://github.com/openai/codex/pull/13046) adopted it in the
zsh-fork interception path.
The remaining gap was the preflight execpolicy check in
`core/src/exec_policy.rs`. That path derives approval requirements
before execution for `shell`, `shell_command`, and `unified_exec`, but
it was still using the default exact-token matcher.
As a result, a command that already included an absolute executable
path, such as `/usr/bin/git status`, could still miss a basename rule
like `prefix_rule(pattern = ["git"], ...)` during preflight even when
the policy also defined a matching `host_executable(name = "git", ...)`
entry.
This PR brings the same opt-in `host_executable()` resolution to the
preflight approval path when an absolute program path is already present
in the parsed command.
## What Changed
- updated
`ExecPolicyManager::create_exec_approval_requirement_for_command()` in
`core/src/exec_policy.rs` to use `check_multiple_with_options(...)` with
`MatchOptions { resolve_host_executables: true }`
- kept the existing shell parsing flow for approval derivation, but now
allow basename rules to match absolute executable paths during preflight
when `host_executable()` permits it
- updated requested-prefix amendment evaluation to use the same
host-executable-aware matching mode, so suggested `prefix_rule()`
amendments are checked consistently for absolute-path commands
- added preflight coverage for:
- absolute-path commands that should match basename rules through
`host_executable()`
- absolute-path commands whose paths are not in the allowed
`host_executable()` mapping
- requested prefix-rule amendments for absolute-path commands
## Verification
- `just fix -p codex-core`
- `cargo test -p codex-core --lib exec_policy::tests::`
## Summary
- skip online model refresh for subagent sessions
- avoid rollout flushes during subagent startup
- keep /models refresh for non-subagent sessions
