# Why
Add product analytics for hook handler executions so we can understand
which hooks are running, where they came from, and whether they
completed, failed, stopped, or blocked work.
# What
- add the new `codex_hook_run` analytics event and payload plumbing in
`codex-rs/analytics`
- emit hook-run analytics from the shared hook completion path in
`codex-rs/core`
- classify hook source from the loaded hook path as `system`, `user`,
`project`, or `unknown`
```
{
"event_type": "codex_hook_run",
"event_params": {
"thread_id": "string",
"turn_id": "string",
"model_slug": "string",
"hook_name": "string, // any HookEventName
"hook_source": "system | user | project | unknown",
"status": "completed | failed | stopped | blocked"
}
}

## Summary
- replace the unsubscribe-during-turn test's sleep/polling flow with a
gated streaming SSE response
- add request-count notification support to the streaming SSE test
server so the test can wait for the in-flight Responses request
deterministically
## Scope
- codex-rs/app-server/tests/suite/v2/thread_unsubscribe.rs
- codex-rs/core/tests/common/streaming_sse.rs
## Validation
- Not run locally; this is a narrow extraction from the prior CI-green
branch.

This was flagged by the Codex Security tool: the `state` lock was held
longer than necessary, which included being held across an `async` call,
increasing the potential for deadlock.
While this was flagged by the Codex Security tool, I will look into
enabling
https://rust-lang.github.io/rust-clippy/stable/index.html#await_holding_lock
in a follow-up PR (though unfortunately, that Clippy rule claims it
reports false positives when `drop()` is used to drop a guard instead of
using the end of block scope to drop). Though I can't seem to find a
Clippy rule that checks for opportunities to drop a guard as soon as it
is no longer referenced, in general.
## 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.
## Summary
- Add an explicit stdin mode to process/start.
- Keep normal non-interactive exec stdin closed while allowing
pipe-backed processes.

## 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`
- `just fix -p codex-core`

## 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`
## 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`
## Summary
- Add an MCP server environment setting with local as the default.
- Thread the default through config serialization, schema generation,
and existing config fixtures.

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
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.

- [x] Add resource uri meta to tool call item so that the app-server
client can start prefetching resources immediately without loading mcp
server status.
## Summary
- Promote `Feature::ToolSearch` to `Stable` and enable it in the default
feature set
- Update feature tests and tool registry coverage to match the new
default
- Adjust the search-tool integration test to assert the default-on path
and explicit disable fallback
## Testing
- `just fmt`
- `cargo test -p codex-features`
- `cargo test -p codex-core --test all search_tool`
- `cargo test -p codex-tools`
**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
## Testing
- cargo test -p codex-api

## 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.
# 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

## 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](ff2d3c1e72/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`
## Summary
- Move auth header construction into the
`AuthProvider::add_auth_headers` contract.
- Inline `CoreAuthProvider` header mutation in its provider impl and
remove the shared header-map helper.
- Update HTTP, websocket, file upload, sideband websocket, and test auth
callsites to use the provider method.
- Add direct coverage for `CoreAuthProvider` auth header mutation.
## Testing
- `just fmt`
- `cargo test -p codex-api`
- `cargo test -p codex-core

Builds on top of #17659
Move the filesystem + sqlite thread listing-related operations inside of
a local ThreadStore implementation and call ThreadStore from the places
that used to perform these filesystem/sqlite operations.
This is the first of a series of PRs that will implement the rest of the
local ThreadStore.
Testing:
- added unit tests for the thread store implementation
- adjusted some unit tests in the realtime + personality packages whose
callsites changed. Specifically I'm trying to hide ThreadMetadata inside
of the local implementation and make ThreadMetadata a sqlite
implementation detail concern rather than a public interface, preferring
the more generate StoredThread interface instead
- added a corner case test for the personality migration package that
wasn't covered by the existing test suite
- adjust the behavior of searched thread listing to run the existing
local rollout repair/backfill pass _before_ querying SQLite results, so
callers using ThreadStore::list_threads do not miss matches after a
partial metadata warm-up
## Summary
Stack PR 2 of 4 for feature-gated agent identity support.
This PR adds agent identity registration behind
`features.use_agent_identity`. It keeps the app-server protocol
unchanged and starts registration after ChatGPT auth exists rather than
requiring a client restart.
## Stack
- PR1: https://github.com/openai/codex/pull/17385 - add
`features.use_agent_identity`
- PR2: https://github.com/openai/codex/pull/17386 - this PR
- PR3: https://github.com/openai/codex/pull/17387 - register agent tasks
when enabled
- PR4: https://github.com/openai/codex/pull/17388 - use `AgentAssertion`
downstream when enabled
## Validation
Covered as part of the local stack validation pass:
- `just fmt`
- `cargo test -p codex-core --lib agent_identity`
- `cargo test -p codex-core --lib agent_assertion`
- `cargo test -p codex-core --lib websocket_agent_task`
- `cargo test -p codex-api api_bridge`
- `cargo build -p codex-cli --bin codex`
## Notes
The full local app-server E2E path is still being debugged after PR
creation. The current branch stack is directionally ready for review
while that follow-up continues.
stacked on #17402.
MCP tools returned by `tool_search` (deferred tools) get registered in
our `ToolRegistry` with a different format than directly available
tools. this leads to two different ways of accessing MCP tools from our
tool catalog, only one of which works for each. fix this by registering
all MCP tools with the namespace format, since this info is already
available.
also, direct MCP tools are registered to responsesapi without a
namespace, while deferred MCP tools have a namespace. this means we can
receive MCP `FunctionCall`s in both formats from namespaces. fix this by
always registering MCP tools with namespace, regardless of deferral
status.
make code mode track `ToolName` provenance of tools so it can map the
literal JS function name string to the correct `ToolName` for
invocation, rather than supporting both in core.
this lets us unify to a single canonical `ToolName` representation for
each MCP tool and force everywhere to use that one, without supporting
fallbacks.
## Summary
- Fix marketplace-add local path detection on Windows by using
`Path::is_absolute()`.
- Make marketplace-add local-source tests parse/write TOML through the
same helpers instead of raw string matching.
- Update `rand` 0.9.x to 0.9.3 and document the remaining audited `rand`
0.8.5 advisory exception.
- Refresh `MODULE.bazel.lock` after the Cargo.lock update.
## Why
Latest `main` had two independent CI blockers: marketplace-add tests
were not portable to Windows path/TOML escaping, and cargo-deny still
reported `RUSTSEC-2026-0097` after the recent rustls-webpki fix.
## Validation
- `cargo test -p codex-core marketplace_add -- --nocapture`
- `cargo deny --all-features check`
- `just bazel-lock-check`
- `just fix -p codex-core`
- `just fmt`
- `git diff --check`
## Changes
Allows MCPs to opt in to receiving sandbox config info through `_meta`
on model-initiated tool calls. This lets MCPs adhere to the thread's
sandbox if they choose to.
## Details
- Adds the `codex/sandbox-state-meta` experimental MCP capability.
- Tracks whether each MCP server advertises that capability.
- When a server opts in, `codex-core` injects the current `SandboxState`
into model-initiated MCP tool-call request `_meta`.
## Verification
- added an integration test for the capability
`exec()` had a number of arguments that were unused, making the function
signature misleading. This PR aims to clean things up to clarify the
role of this function and to clarify which fields of `ExecParams` are
unused and why.
## Why
`spawn_command_under_seatbelt()` in `codex-rs/core/src/seatbelt.rs` had
fallen out of production use and was only referenced by test-only
wrappers. That left us with sandbox tests that could stay green even if
the actual seatbelt exec path regressed, because production shell
execution now flows through `SandboxManager::transform()` and
`ExecRequest::from_sandbox_exec_request()` instead of that helper.
Removing the dead helper also exposed one downstream `codex-exec`
integration test that still imported it, which broke `just clippy`.
## What Changed
- Removed `codex-rs/core/src/seatbelt.rs` and stopped exporting
`codex_core::seatbelt`.
- Removed the redundant `codex-rs/core/tests/suite/seatbelt.rs` coverage
that only exercised the dead helper.
- Kept the `openpty` regression check, but moved it into
`codex-rs/core/tests/suite/exec.rs` so it now runs through
`process_exec_tool_call()`.
- Fixed the seatbelt denial test in `codex-rs/core/tests/suite/exec.rs`
to use `/usr/bin/touch`, so it actually exercises the sandbox instead of
a nonexistent path.
- Updated `codex-rs/exec/tests/suite/sandbox.rs` on macOS to build the
sandboxed command through `build_exec_request()` and spawn the
transformed command, instead of importing the removed helper.
- Left the lower-level seatbelt policy coverage in
`codex-rs/sandboxing/src/seatbelt_tests.rs`, where the policy generator
is still covered directly.
## Verification
- `cargo test -p codex-core suite::exec::`
- `cargo test -p codex-exec`
- `cargo clippy -p codex-exec --tests -- -D warnings`
## Summary
- reuse a shared remote exec-server for remote-aware codex-core
integration tests within a test binary process
- keep per-test remote cwd creation and cleanup so tests retain
workspace isolation
- leave codex_self_exe, codex_linux_sandbox_exe, cwd_path(), and
workspace_path() behavior unchanged
## Validation
- rustfmt codex-rs/core/tests/common/test_codex.rs
- git diff --check
- CI is running on the updated branch
