## Summary
- Add best-effort auto-upgrade for user-configured Git marketplaces
recorded in `config.toml`.
- Track the last activated Git revision with `last_revision` so
unchanged marketplace sources skip clone work.
- Trigger the upgrade from plugin startup and `plugin/list`, while
preserving existing fail-open plugin behavior with warning logs rather
than new user-visible errors.
## Details
- Remote configured marketplaces use `git ls-remote` to compare the
source/ref against the recorded revision.
- Upgrades clone into a staging directory, validate that
`.agents/plugins/marketplace.json` exists and that the manifest name
matches the configured marketplace key, then atomically activate the new
root.
- Local `.agents/plugins/marketplace.json` marketplaces remain live
filesystem state and are not auto-pulled.
- Existing non-curated plugin cache refresh is kicked after successful
marketplace root upgrades.
## Validation
- `just write-config-schema`
- `cargo test -p codex-core marketplace_upgrade`
- `cargo check -p codex-cli -p codex-app-server`
- `just fix -p codex-core`
Did not run the complete `cargo test` suite because the repo
instructions require asking before a full core workspace run.
Addresses #17951
Problem: The TUI treated skills/list failures as fatal during refresh,
so proxy/firewall responses that break plugin discovery could crash the
session.
Solution: Route startup and refresh skills/list responses through shared
graceful handling that logs a warning and keeps the TUI running.
## Summary
- Add an explicit stdin mode to process/start.
- Keep normal non-interactive exec stdin closed while allowing
pipe-backed processes.

- Add a "remote" thread store implementation
- Implement the remote thread store as a thin wrapper that makes grpc
calls to a configurable service endpoint
- Implement only the thread/list method to start
- Encode the grpc method/param shape as protobufs in the remote
implementation
A wart: the proto generation script is an "example" binary target. This
is an example target only because Cargo lets examples use
dev-dependencies, which keeps tonic-prost-build out of the normal
codex-thread-store dependency surface. A regular bin would either need
to add proto generation deps as normal runtime deps, or use a
feature-gated optional dep, which this repo’s manifest checks explicitly
reject.
## Summary
This makes `DangerFullAccess` / yolo tool execution fully opt out of
managed-network enforcement.
Previously, yolo turns could have `turn.network` stripped while tool
orchestration still derived `enforce_managed_network=true` from
`requirements.toml.network`. That created an inconsistent state where
the turn had no managed proxy attached, but tool execution still behaved
like managed networking was active.
This updates the tool orchestration and JS REPL paths to treat managed
networking as active only when the current turn actually has
`turn.network`.
## Behavior
- Yolo / `DangerFullAccess`: no managed proxy, no managed-network
enforcement.
- Guardian / workspace-write with managed proxy: managed-network
enforcement still applies.
- Avoids the half-state where yolo has no proxy but still gets
managed-network sandbox behavior.
## Tests
- `just fmt`
- `cargo test -p codex-core
danger_full_access_tool_attempts_do_not_enforce_managed_network --
--nocapture`
- `cargo test -p codex-core danger_full_access -- --nocapture`

## Summary
- Promote `image_generation` from under-development to stable
- Enable image generation by default in the feature registry
- Update feature coverage for the new launch-state expectation
- Add the missing image-generation auth fixture field in a tool registry
test
## Testing
- `just fmt`
- `cargo test -p codex-features`
- `cargo test -p codex-tools` currently fails:
`test_full_toolset_specs_for_gpt5_codex_unified_exec_web_search` needs
its expected default tool list updated for `image_generation`
Addresses #18011
Problem: #16987 allowed zero-token TUI exits to print resume hints,
which exposed precomputed thread ids before their rollout files were
persisted; #17222 made the same invalid hint visible when switching
sessions via `/resume`.
Solution: Only include resume commands for TUI sessions backed by a
materialized non-empty rollout, and cover both missing-rollout and
persisted-rollout summary behavior.
Testing: Manually verified by pressing Ctrl+D before the first prompt
and confirming that no "to continue this session" message was generated.
Addresses #12178
Problem: The TUI /rename prompt opened blank even when the current
thread already had a custom name, making small edits awkward.
Solution: Let custom prompts receive initial text and prefill /rename
with the existing thread name while preserving the empty prompt for
unnamed threads.
Testing: Manually verified that the feature works by using `/rename`
with unnamed and already-named threads.
## Summary
- hide deferred MCP/app nested tool descriptions from the `exec` prompt
in code mode
- add short guidance that omitted nested tools are still available
through `ALL_TOOLS`
- cover the code_mode_only path with an integration test that discovers
and calls a deferred app tool
## Motivation
`code_mode_only` exposes only top-level `exec`/`wait`, but the `exec`
description could still include a large nested-tool reference. This
keeps deferred nested tools callable while avoiding that prompt bloat.
## Tests
- `just fmt`
- `just fix -p codex-code-mode`
- `just fix -p codex-tools`
- `cargo test -p codex-code-mode
exec_description_mentions_deferred_nested_tools_when_available`
- `cargo test -p codex-tools
create_code_mode_tool_matches_expected_spec`
- `cargo test -p codex-core
code_mode_only_guides_all_tools_search_and_calls_deferred_app_tools`
Addresses #18045
Problem: `/statusline` exposed both `context-remaining` and
`context-remaining-percent` after conflicting PRs attempted to address
the same context-status issue, including #17637, allowing duplicate
footer segments.
Solution: Remove the duplicate `context-remaining-percent` status-line
item and update status-line tests and snapshots to use only canonical
`context-remaining`.
## Summary
- Add an MCP server environment setting with local as the default.
- Thread the default through config serialization, schema generation,
and existing config fixtures.

Fix app-server startup when `remote_control = true` is enabled without
ChatGPT auth.
Remote control now starts in a degraded/retrying state instead of
failing app-server initialization, so Desktop is not stranded before the
initial initialize handshake.
Get rid of an `expect()` that caused a `panic` in the TUI

Basically in `from_absolute_path` there is a `absolutize::absolutize`
that calls a `current_dir()` . But the dir in which Codex was running
got re-generated (because of Codex I guess but I can't exactly see the
source). So `current_dir()` returns an `ENOENT` and 💥
Make sure Bazel logs shows every errors so that we can debug flakes +
fix a small flake on Windows by updating the sleep command to a
`Start-Sleep` instead of a PowerShell nested command (otherwise we had
double nesting which is absurdely slow)
Stabilizes the Responses API proxy header test by splitting the coverage
at the right boundary:
- Core integration test now verifies parent/subagent identity headers
directly from captured `/responses` requests.
- Proxy dump unit test now verifies those identity headers are preserved
in dumped request JSON.
- Removes the flaky real proxy process + temp-file dump polling path
from the core test.
## Summary
- parse chatgpt_account_is_fedramp from signed ChatGPT auth metadata
- add _account_is_fedramp=true to ChatGPT backend-api requests only for
FedRAMP ChatGPT-auth accounts
Addresses https://github.com/openai/codex/issues/17143
Problem: TUI interrupts without an active turn stopped cancelling slow
MCP startup after routing through the app-server APIs.
Solution: Route no-active-turn interrupts through app-server as startup
cancels, acknowledge them immediately, and emit cancelled MCP startup
updates.
Testing: I manually confirmed that MCP cancellation didn't work prior to
this PR and works after the fix was in place.
Split plugin loading, marketplace, and related infrastructure out of
core into codex-core-plugins, while keeping the core-facing
configuration and orchestration flow in codex-core.

## Summary
- Make command/exec output-delta tests accumulate streamed chunks
instead of assuming complete logical output in a single notification.
- Collect stdout and stderr independently so stream interleaving does
not fail the pipe streaming test.
## Why
The command/exec protocol exposes output as deltas, so tests should not
rely on chunk boundaries being stable. A line like `out-start\n` may
arrive split across multiple notifications, and stdout/stderr
notifications may interleave.
## Validation
- `just fmt`
- `git diff --check`
- `cargo test -p codex-app-server suite::v2::command_exec`
**Summary**
- prevent managed requirements.toml network settings from leaking into
DangerFullAccess / yolo turns by gating managed proxy attachment on
sandbox mode
- keep guardian/sandboxed modes on the managed proxy path, while making
true yolo bypass the proxy entirely, including /shell full-access
commands
## Summary
- wrap realtime startup context in
`<startup_context>...</startup_context>` tags
- prefix V2 mirrored user text and relayed backend text with `[USER]` /
`[BACKEND]`
- remove the V2 progress suffix and replace the final V2 handoff output
with a short completion acknowledgement while preserving the existing V1
wrapper

## Summary
This PR significantly improves the standalone installer experience.
The main changes are:
1. We now install the codex binary and other dependencies in a
subdirectory under CODEX_HOME.
(`CODEX_HOME/packages/standalone/releases/...`)
2. We replace the `codex.js` launcher that npm/bun rely on with logic in
the Rust binary that automatically resolves its dependencies (like
ripgrep)
## Motivation
A few design constraints pushed this work.
1. Currently, the entrypoint to codex is through `codex.js`, which
forces a node dependency to kick off our rust app. We want to move away
from this so that the entrypoint to codex does not rely on node or
external package managers.
2. Right now, the native script adds codex and its dependencies directly
to user PATH. Given that codex is likely to add more binary dependencies
than ripgrep, we want a solution which does not add arbitrary binaries
to user PATH -- the only one we want to add is the `codex` command
itself.
3. We want upgrades to be atomic. We do not want scenarios where
interrupting an upgrade command can move codex into undefined state (for
example, having a new codex binary but an old ripgrep binary). This was
~possible with the old script.
4. Currently, the Rust binary uses heuristics to determine which
installer created it. These heuristics are flaky and are tied to the
`codex.js` launcher. We need a more stable/deterministic way to
determine how the binary was installed for standalone.
5. We do not want conflicting codex installations on PATH. For example,
the user installing via npm, then installing via brew, then installing
via standalone would make it unclear which version of codex is being
launched and make it tough for us to determine the right upgrade
command.
## Design
### Standalone package layout
Standalone installs now live under `CODEX_HOME/packages/standalone`:
```text
$CODEX_HOME/
packages/
standalone/
current -> releases/0.111.0-x86_64-unknown-linux-musl
releases/
0.111.0-x86_64-unknown-linux-musl/
codex
codex-resources/
rg
```
where `standalone/current` is a symlink to a release directory.
On Windows, the release directory has the same shape, with `.exe` names
and Windows helpers in `codex-resources`:
```text
%CODEX_HOME%\
packages\
standalone\
current -> releases\0.111.0-x86_64-pc-windows-msvc
releases\
0.111.0-x86_64-pc-windows-msvc\
codex.exe
codex-resources\
rg.exe
codex-command-runner.exe
codex-windows-sandbox-setup.exe
```
This gives us:
- atomic upgrades because we can fully stage a release before switching
`standalone/current`
- a stable way for the binary to recognize a standalone install from its
canonical `current_exe()` path under CODEX_HOME
- a clean place for binary dependencies like `rg`, Windows sandbox
helpers, and, in the future, our custom `zsh` etc
### Command location
On Unix, we add a symlink at `~/.local/bin/codex` which points directly
to the `$CODEX_HOME/packages/standalone/current/codex` binary. This
becomes the main entrypoint for the CLI.
On Windows, we store the link at
`%LOCALAPPDATA%\Programs\OpenAI\Codex\bin`.
### PATH persistence
This is a tricky part of the PR, as there's no ~super reliable way to
ensure that we end up on PATH without significant tradeoffs.
Most Unix variants will have `~/.local/bin` on PATH already, which means
we *should* be fine simply registering the command there in most cases.
However, there are cases where this is not the case. In these cases, we
directly edit the profile depending on the shell we're in.
- macOS zsh: `~/.zprofile`
- macOS bash: `~/.bash_profile`
- Linux zsh: `~/.zshrc`
- Linux bash: `~/.bashrc`
- fallback: `~/.profile`
On Windows, we update the User `Path` environment variable directly and
we don't need to worry about shell profiles.
### Standalone runtime detection
This PR adds a new shared crate, `codex-install-context`, which computes
install ownership once per process and caches it in a `OnceLock`.
That context includes:
- install manager (`Standalone`, `Npm`, `Bun`, `Brew`, `Other`)
- the managed standalone release directory, when applicable
- the managed standalone `codex-resources` directory, when present
- the resolved `rg_command`
The standalone path is detected by canonicalizing `current_exe()`,
canonicalizing CODEX_HOME via `find_codex_home()`, and checking whether
the binary is running from under
`$CODEX_HOME/packages/standalone/releases`.
We intentionally do not use a release metadata file. The binary path is
the source of truth.
### Dependency resolution
For standalone installs, `grep_files` now resolves bundled `rg` from
`codex-resources` next to the Codex binary.
For npm/bun/brew/other installs, `grep_files` falls back to resolving
`rg` from PATH.
For Windows standalone installs, Windows sandbox helpers are still found
as direct siblings when present. If they are not direct siblings, the
lookup also checks the sibling `codex-resources` directory.
### TUI update path
The TUI now has `UpdateAction::StandaloneUnix` and
`UpdateAction::StandaloneWindows`, which rerun the standalone install
commands.
Unix update command:
```sh
sh -c "curl -fsSL https://chatgpt.com/codex/install.sh | sh"
```
Windows update command:
```powershell
powershell -c "irm https://chatgpt.com/codex/install.ps1|iex"
```
The Windows updater runs PowerShell directly. We do this because `cmd
/C` would parse the `|iex` as a cmd pipeline instead of passing it to
PowerShell.
## Additional installer behavior
- standalone installs now warn about conflicting npm/bun/brew-managed
`codex` installs and offer to uninstall them
- same-version reruns do not redownload the release if it is already
staged locally
## Testing
Installer smoke tests run:
- macOS: fresh install into isolated `HOME` and `CODEX_HOME` with
`scripts/install/install.sh --release latest`
- macOS: reran the installer against the same isolated install to verify
the same-version/update path and PATH block idempotence
- macOS: verified the installed `codex --version` and bundled
`codex-resources/rg --version`
- Windows: parsed `scripts/install/install.ps1` with PowerShell via
`[scriptblock]::Create(...)`
- Windows: verified the standalone update action builds a direct
PowerShell command and does not route the `irm ...|iex` command through
`cmd /C`

## Summary
- honor `_meta["codex/imageDetail"] == "original"` on MCP image content
and map it to `detail: "original"` where supported
- strip that detail back out when the active model does not support
original-detail image inputs
- update code-mode `image(...)` to accept individual MCP image blocks
- teach `js_repl` / `codex.emitImage(...)` to preserve the same hint
from raw MCP image outputs
- document the new `_meta` contract and add generic RMCP-backed coverage
across protocol, core, code-mode, and js_repl paths
## Summary
1. Revert https://github.com/openai/codex/pull/17848 so the Bazel and
`BUILD` file changes leave `main`.
2. Prepare for a narrower follow up that restores only `SECURITY.md`.
## Validation
1. Reviewed the revert diff against `main`.
2. Ran a clean diff check before push.
- Discover marketplace manifests from different supported layout paths
instead of only .agents/plugins/marketplace.json.
- Accept local plugin sources written either as { source: "local", path:
... } or as a direct string path.
- Skip unsupported or invalid plugin source entries without failing the
entire marketplace, and keep valid local plugins loadable.
Dismiss stale TUI app-server approvals after remote resolution
When an approval, user-input prompt, or elicitation request is resolved
by another client, the TUI now dismisses the matching local UI instead
of leaving stale prompts behind and emitting a misleading local
cancellation.
This change teaches pending app-server request tracking to map
`serverRequest/resolved` notifications back to the concrete request type
and stable request key, then propagates that resolved request into TUI
prompt state. Approval, request-user-input, and MCP elicitation overlays
now drop the resolved current or queued request quietly, advance to the
next queued request when present, and avoid emitting abort/cancel events
for stale UI.
The latest update also retires matching prompts while they are still
deferred behind active streaming and suppresses buffered active-thread
requests whose app-server request id has already been resolved before
drain. `ChatWidget` removes a resolved request from both the deferred
interrupt queue and the materialized bottom-pane stack, while
active-thread request handling verifies the app-server request is still
pending before showing a prompt. Lifecycle events such as exec begin/end
remain queued so approved work can still render normally.
Tests cover resolved-request mapping, overlay dismissal behavior,
deferred prompt pruning for same-turn user input, exec approval IDs,
lifecycle-event retention, and the buffered active-thread ordering
regression.
Validation:
- `just fmt`
- `git diff --check`
- `cargo test -p codex-tui
resolved_buffered_approval_does_not_become_actionable_after_drain`
- `cargo test -p codex-tui
enqueue_primary_thread_session_replays_buffered_approval_after_attach`
- `cargo test -p codex-tui chatwidget::interrupts`
- `just fix -p codex-tui`

## Summary
- Re-enable remote variants for the exec-server filesystem
sandbox/symlink tests that were made local-only in PR #17671.
- Restore `use_remote` parameterization for the readable-root,
normalized symlink escape, symlink removal, and symlink
copy-preservation cases.
- Preserve `mode={use_remote}` context on key async filesystem failures
so CI failures point at the local or remote lane.
## Validation
- `cd codex-rs && just fmt`
- Not run: `bazel test
//codex-rs/exec-server:exec-server-file_system-test` per local Codex
development guidance to avoid test runs unless explicitly requested.

# Summary
- implement local ThreadStore archive/unarchive operations
- implement local ThreadStore read_thread operation
- break up the various ThreadStore local method implementations into
separate files
- migrate app-server archive/unarchive and core archive fixture to use
ThreadStore (but not all read operations yet!)
- use the ThreadStore's read operation as a proxy check for thread
persistence/existence in the app server code
- move all other filesystem operations related to archive (path
validation etc) into the local thread store.
# Tests
- add dedicated local store archive/unarchive tests
## Summary
1. Add a Security Boundaries section to `SECURITY.md`.
2. Point readers to the Codex Agent approvals and security documentation
for sandboxing, approvals, and network controls.
## Validation
1. Reviewed the `SECURITY.md` diff in a clean worktree.
2. No tests run. Docs only change.
Azure Responses providers were still falling back to local compaction
because the compaction gate only checked
`ModelProviderInfo::is_openai()`.
Move the capability check onto `ModelProviderInfo` with
`supports_remote_compaction()`, backed by the existing Azure Responses
endpoint detection used in `codex-api`, and have `core::compact`
delegate to that helper.
Add regression coverage for:
- OpenAI providers using remote compaction
- Azure providers using remote compaction
- non-OpenAI/non-Azure providers staying on the local path
resolves#17773

Co-authored-by: Michael Bolin <mbolin@openai.com>
## Why
#17763 moved sandbox-state delivery for MCP tool calls to request
`_meta` via the `codex/sandbox-state-meta` experimental capability.
Keeping the older `codex/sandbox-state` capability meant Codex still
maintained a second transport that pushed updates with the custom
`codex/sandbox-state/update` request at server startup and when the
session sandbox policy changed.
That duplicate MCP path is redundant with the per-tool-call metadata
path and makes the sandbox-state contract larger than needed. The
existing managed network proxy refresh on sandbox-policy changes is
still needed, so this keeps that behavior separate from the removed MCP
notification.
## What Changed
- Removed the exported `MCP_SANDBOX_STATE_CAPABILITY` and
`MCP_SANDBOX_STATE_METHOD` constants.
- Removed detection of `codex/sandbox-state` during MCP initialization
and stopped sending `codex/sandbox-state/update` at server startup.
- Removed the `McpConnectionManager::notify_sandbox_state_change`
plumbing while preserving the managed network proxy refresh when a user
turn changes sandbox policy.
- Slimmed `McpConnectionManager::new` so startup paths pass only the
initial `SandboxPolicy` needed for MCP elicitation state.
- Kept `codex/sandbox-state-meta` support intact; servers that opt in
still receive the current `SandboxState` on tool-call request `_meta`
([remaining call
path](https://github.com/openai/codex/blob/ff2d3c1e72ff08ce13743b99605d19d338edd51c/codex-rs/core/src/mcp_tool_call.rs#L487-L526)).
- Added regression coverage for refreshing the live managed network
proxy on a per-turn sandbox-policy change.
## Verification
- `cargo test -p codex-core
new_turn_refreshes_managed_network_proxy_for_sandbox_change`
- `cargo test -p codex-mcp`
