## What changed
- Make the shell and PowerShell installers download release metadata and assets from `releases.openai.com` by default, with bounded request timeouts.
- Fall back to GitHub Releases when metadata is unusable, required assets are missing, or downloaded assets fail checksum or manifest validation.
- Document `CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false` for opting out of the default release source.
## Testing
- Cover default-source installation, malformed and incomplete metadata, version mismatches, corrupt assets, invalid checksums, incomplete manifests, and GitHub fallback failures in the shell installer tests.
GitOrigin-RevId: 1c65d527ca79761358c3a4cd7a5fd675e1ef75b2
## What changed
- Add a default-on `features.multi_agent_v2.wait_agent_enabled` setting.
- Omit `collaboration.wait_agent` from the tool plan when the setting is disabled, independently of `features.current_time_reminder.sleep_tool`.
## Testing
- Cover configuration parsing and tool exposure with both clock sleep states.
GitOrigin-RevId: c2f34c5edd5bc191d6a5ac41d7bbb80708da1202
## What changed
- Send `codex-mcp-client/<version>` as the default user agent for streamable HTTP and OAuth requests.
- Preserve user agents supplied through configured HTTP headers.
## Testing
- Verify the default user agent on OAuth discovery, token refresh, and MCP initialization requests.
- Verify that a configured user agent overrides the default.
GitOrigin-RevId: 659ef8f126df97b3c1b4d01e9e542a673b5ef42b
## What changed
- Make `plugin/list` requests with `forceRefetch: true` wait for configured
local plugin caches to finish reconciling before building the response.
- Track marketplace plugin sources when deduplicating refreshes so source
changes can trigger a reinstall even when the plugin version is unchanged.
- Notify effective-plugin consumers when the awaited refresh changes the cache.
## Testing
Added coverage showing that a forced local plugin listing returns an upgraded
plugin from the same marketplace path only after the new version is installed
and the superseded cache entry is removed.
GitOrigin-RevId: c1b59f3be6cc19dac8db39aaea548ddf8e342f1d
## Why
An idle thread with an outstanding durable sleep must resume when agent work
arrives, even when that message would normally remain queued without triggering a
turn.
## What changed
- Treat any pending mailbox message as wake-up work while a durable sleep is
attached to the thread.
- Keep requiring `trigger_turn` for idle threads that are not durably asleep.
- Cover waking a sleeping root thread from queue-only agent mail and persisting
the message in thread history.
GitOrigin-RevId: e361ac1b104436d4d63aebfe5e2422691a1cc139
## What changed
- Load app metadata for plugin read and install responses through the authenticated batch API, splitting requests into batches of 100 and retaining cached metadata if a batch fails.
- Preserve every declared app in plugin responses, using its ID as the fallback name and retaining categories from the plugin declaration when metadata is unavailable.
- Add `isEnabled`, `disabledReason`, and `isReadOnly` to `AppToolSummary`, with defaults that keep legacy responses compatible.
## Testing
- Cover plugin reads with more than 100 apps, partial batch failures, install-time authentication results, tool-state propagation, and legacy tool summaries.
GitOrigin-RevId: 14000df9c5c94dde781358e292a8bef741c5dd23
## What changed
Skip registering the standalone `image_generation` tool when cached
authentication identifies the account plan as Free. Leave the existing
feature, provider capability, model modality, and authorization checks intact
for other account plans.
GitOrigin-RevId: 54d3b73dc610e508db7e281c4d7a8e72961e35a6
## What changed
- Cache global, user, and workspace remote plugin catalogs on disk with a three-hour TTL and scope- and account-specific keys.
- Serve cached catalogs from `plugin/list`, refresh stale entries in the background, and warm existing caches at app-server startup without blocking list requests.
- Make `forceRefetch: true` bypass cached catalog data and replace an entry only after a successful fetch.
- Invalidate user and workspace catalog caches after remote plugin sharing changes.
## Testing
- Cover cache freshness, scope isolation, legacy global cache compatibility, identity requirements for private catalogs, forced refetches, and non-blocking startup refreshes.
GitOrigin-RevId: 7844e9dfb72e43b26d749b4afd16fd9c1793caba
## Why
Parent context-window and auto-compaction overrides may describe a different
model than the one selected for Guardian review.
## What changed
- Clear `model_context_window` and `model_auto_compact_token_limit` when the
effective Guardian model differs from the parent model, allowing the review
model's own limits to apply.
- Preserve those overrides when Guardian uses the same effective model.
## Testing
Add unit coverage for both model-selection paths and verify that a Guardian
rollout records the selected review model's context window.
GitOrigin-RevId: ebc399f4eba37c7f279fd0d258154c00d45e2d00
## What changed
- Add the `supports_standalone_web_search` model-provider setting, defaulting to `false`, and preserve it in remote thread configuration.
- Enable the standalone `web.run` tool for opted-in custom Responses providers when web search is enabled and the runtime provider supports it.
- Send standalone search requests through the custom provider's endpoint and authentication.
## Testing
- Cover opt-in, default-off, disabled-search, and unsupported-provider behavior.
- Verify custom-provider search request routing and authorization through the app server.
GitOrigin-RevId: 7c5f96b0ce924ad2b9715c45bfc635e89fc39cff
## Why
Multi-agent mode instructions are durable model context and need to survive
history changes without re-emitting unrelated setup hints.
## What changed
- Add a `multi_agent_mode` world-state section that diffs, retains, and restores
the effective mode instructions.
- Persist mode changes in world-state snapshots while keeping the legacy
`TurnContextItem.multi_agent_mode` field for reading older rollouts.
- Keep initial mode instructions after the root-agent usage hint so the active
mode takes precedence, and bound custom mode text before snapshotting it.
## Testing
- Add snapshot coverage for mode transitions, retained history, and custom-text
truncation.
- Verify live mode changes preserve instruction ordering, avoid duplicating the
usage hint, and record both modes in world state.
GitOrigin-RevId: 96b9964d6e5299b07a011c559b68e3d948a49226
## What changed
Remove `first_party_type` from connector app metadata and the app-server v2
protocol. Update metadata conversion and merge paths, generated JSON and
TypeScript schemas, and affected test fixtures to match.
GitOrigin-RevId: 3f2e56eca68352360d8c0d99d48486ae65d664c1
## What changed
- Add `isPinned` to thread responses and allow `thread/metadata/update` to pin or unpin stored threads.
- Add an `isPinned` filter to `thread/list`, including cursor-based pagination and combinations with relationship filters.
- Persist pin state in SQLite without modifying rollout files, default existing threads to unpinned, and preserve pins through reconciliation and archive transitions.
## Testing
- Cover protocol serialization, database migration and indexing, pin updates, filtered pagination, rollout reconciliation, and archive/unarchive behavior.
GitOrigin-RevId: c2eacabd6dae465e2ae6ce8a169e00740960cdb7
## Why
Interrupting a turn while MCP tools were still starting could abort before the
submitted user input was recorded in conversation history.
## What changed
- Build and retain the MCP tool list and tool router as part of each step
snapshot, using the turn cancellation token during tool discovery.
- Record turn hooks and submitted input when cancellation occurs during startup
prewarming, pre-sampling compaction, or first-step capture.
- Reuse the captured router for sampling, compaction, and prompt debugging so
advertised and executable tools share the same request-scoped view.
## Testing
Add coverage that interrupts each affected MCP startup phase and verifies that
the user prompt remains in history before the turn-aborted marker.
GitOrigin-RevId: 6e96c6814357a55545d69b580e28f35933cfadf7
## What changed
- Add `compaction_ms` to turn profile facts and turn analytics events.
- Measure manual and automatic compaction as an exclusive profile phase instead of including it in surrounding idle time.
- Complete the profile and total turn duration from the same instant so their elapsed times remain consistent.
## Testing
- Cover compaction phase accounting and profile-duration consistency.
- Update turn event serialization coverage for `compaction_ms`.
GitOrigin-RevId: 50f0e1cf19789a807f9f56c2ef763c620a5d641c
## Why
The in-process app server can shut down while analytics for a completed turn are
still queued, preventing the completed-turn and accepted-line events from being
delivered.
## What changed
- Add a bounded analytics queue flush that waits for all preceding facts to be
processed.
- Flush analytics after the in-process runtime drains its outbound work and
before acknowledging shutdown.
- Extend the in-process shutdown timeout budgets to cover runtime draining and
the best-effort analytics flush.
## Testing
- Verify that the flush waits for preceding facts and is a no-op when analytics
is disabled.
- Verify that shutdown waits for delayed analytics delivery, including the
completed-turn and accepted-line events produced by a file change.
GitOrigin-RevId: 57ca24e535e5e2f3f3202b2e5498f075676c910a
## Why
Preparing Responses API requests rebuilt tool definitions as a generic JSON
tree, and incremental WebSocket requests cloned their full item prefix for
comparison.
## What changed
- Serialize tool definitions into shared raw JSON that can be embedded directly
in HTTP and WebSocket requests.
- Compare incremental request prefixes in place while still ignoring internal
message metadata.
## Testing
- Verify raw tool JSON matches the existing value encoding.
- Preserve the serialized WebSocket request payload.
GitOrigin-RevId: 66e2921792c332e8904954dafa597f6d39abcf29
## What changed
- Store the spawned session's working directory as a `PathUri` in
`GuardianReviewSessionReuseKey` so reuse comparisons use its canonical URI
representation.
- Assert that the reuse key contains the converted working directory.
GitOrigin-RevId: 68d440a37ebb310c610dabbb3373ed0ceff88dfa
## What changed
- Remove the code-mode skip filter from the shared Bazel CI configuration so
Linux and macOS run the full code-mode integration suite.
- Keep the hidden dynamic-tool callback and ConPTY Ctrl-C tests excluded on
Windows, where they currently time out or cannot reliably interrupt
foreground processes.
- Preserve those exclusions in the Windows cross-build configuration alongside
its PowerShell parser-process exclusion.
GitOrigin-RevId: 1013b9c0c7273ac6618ec3b504d723350b293c1f
## What changed
- Install the git attribution extension in the app server, MCP server, and `codex debug prompt-input` so authenticated workspace policy controls the commit and pull request attribution instructions sent to the model.
- Resolve attribution settings from the process-level ChatGPT base URL, independent of per-thread or per-tool configuration overrides.
- Treat git attribution as contextual developer content when mapping model events.
## Testing
- Cover policy fetch retries, workspace switches, rollbacks, cold thread resumes with legacy instructions, MCP tool calls, and prompt-debug output.
GitOrigin-RevId: 57d182c432c20d7c1c6c429057b6163c9f32088d
## What changed
- Route realtime V3 `bemTags` handoffs using `[ANALYSIS]`, `[COMMENTARY]`, and `[FINAL]` prefixes by default.
- Add `codexResponseHandoffChannelPrefixes` to realtime start requests so clients can replace the accepted prefixes for individual channels. Each channel may accept multiple prefixes, and omitted channels retain their defaults.
- Apply the configured prefixes to both complete and streamed handoff messages, without treating empty prefixes as matches.
## Testing
- Cover request deserialization, default and custom routing, partial streamed prefixes, empty-prefix handling, and end-to-end V3 handoffs.
GitOrigin-RevId: d0aef50aa71362a5beef2c6f6d28b8633da4e529
## What changed
- Add `StartThreadOptions::new` to provide the standard configuration for a new thread.
- Make `ThreadManager::start_thread` the single thread-start entry point and migrate callers from the previous convenience methods.
- Derive default environment selections when `environments` is `None`, while preserving explicit selections, including an empty list.
GitOrigin-RevId: 8977dc11aed54c5e1215a81eaed2b2cf5fc6087a
## What changed
Use the supported `{{ network_access }}` placeholder syntax in the built-in
`danger-full-access`, `read-only`, and `workspace-write` sandbox templates so
permission instructions render the active network access state.
GitOrigin-RevId: 9f8d851016bd7fbedcfc4a9479236b46aca470e8
## What changed
- Add `SqliteConfig` to own the resolved SQLite home, runtime database paths,
and shared read/write and read-only pool settings.
- Pass the configuration through state and local thread-store consumers,
replacing standalone path helpers and duplicated connection setup.
GitOrigin-RevId: 7351b08da94b5c8b6c0bbe492f86aeeca0699d3c
## What changed
- Store the shell approval key's `cwd` as a `PathUri`, matching the URI representation used by approval actions.
- Extend the approval-key test to verify both the URI-based working directory and environment scoping.
## Testing
- Added `approval_key_uses_path_uri_and_includes_environment_id`.
GitOrigin-RevId: 4d7ba1a2e652f4ffe317242f52beb33513b01e6a
## Why
Core-compatible skill catalog output should match the core renderer when the
metadata budget omits entries.
## What changed
- Emit the bounded-catalog omission notice only for `ExtensionCompatible`
rendering.
- Continue tracking omitted entries in `SkillRenderReport` for both policies,
even when `CoreCompatible` produces no fragment because every entry is
omitted.
## Testing
Cover policy-specific omission notices and the case where no minimum skill line
fits within the metadata budget.
GitOrigin-RevId: 79883c15a49c02ff83444ddc272030cb4ddb53c0
## Why
Very long individual lines can make syntax highlighting consume excessive CPU or memory even when the overall input remains below the existing size and line-count limits.
## What changed
- Fall back to plain, unstyled text when any input line exceeds 4 KiB.
- Keep the existing 512 KiB total-size and 10,000-line guardrails.
## Testing
- Cover highlighting fallback and text preservation for a long single-line Bash command.
- Snapshot rendering of a command that exceeds the per-line limit.
GitOrigin-RevId: ba02997331a294d8a32ca89ee06acb12dd3bbd83
Update the git attribution test helper to construct
`WorldStateContributionInput` without the removed `step_store` field.
GitOrigin-RevId: 396b5508f05798f0b43d93f7d02838acdbf97c9b
## Why
The post-sampling trace calculated an estimated token count even when only the
always-on diagnostic and state log sinks were listening, adding unnecessary work
after every sample.
## What changed
- Move the estimate to a dedicated trace target and calculate it only when that
event is enabled.
- Disable the target for the always-on diagnostic and state log sinks while
keeping it available to explicitly configured subscribers.
## Testing
- Verify that the combined always-on subscribers do not enable the estimate
event.
GitOrigin-RevId: ea572584597dda313e7719897d0ab1fdf7362745
## What changed
- Add typed helpers for initialized app-server instances, JSON-RPC requests,
responses, notifications, and thread startup.
- Add a composable `MockResponsesConfig` builder while preserving the existing
mock config writers.
- Migrate the app-server integration suite to the shared helpers, removing
repeated request ID management, deserialization, initialization, and config
assembly.
## Testing
- Add unit coverage for composing mock provider, feature, and extra config, and
for compatibility of the existing mock config writer.
GitOrigin-RevId: 62da177c1d6e8299400de64bd6766567bf1ba3d8
## What changed
- Return a `SkillRenderReport` with total, included, and omitted skill counts,
plus truncated description counts and character totals.
- Keep fragment construction separate from rendering so callers can inspect the
report even when the metadata budget is too small to emit a fragment.
## Testing
- Cover partial description truncation, fully omitted entries, and catalogs
whose omission marker does not fit the budget.
GitOrigin-RevId: e73fdbcf77ac73c7209100ff6c9b5862b6a59a54
## Why
`local` identifies the environment owned by `EnvironmentManager`, but dynamic
remote environment registration previously allowed that ID to be replaced.
## What changed
Reject `local` in the shared environment ID validator used by dynamic remote
environment registration.
GitOrigin-RevId: 2622551f78989c16c432e6dd3d7da9bd8b0527c5
## What changed
- Upgrade `rules_rs` from `0.0.58` to `0.0.96` and LLVM from `0.7.9` to
`0.8.11`, updating extension paths, platform constraints, and compatibility
patches for the current APIs.
- Add native `windows-gnullvm` execution support for the argument-comment lint
toolchain while retaining MSVC execution for existing cross-target builds.
- Build `aws-lc-sys` through the Bazel Central Registry `aws-lc` module and
`rules_rs` integration, removing the replaced crate-specific patches.
GitOrigin-RevId: 9829bcdb6ac74e846b713568aac38ea2fa3c42a2
## What changed
- Require the parent thread to be live before forking its history.
- Read the history mode and multi-agent usage hints from that live parent so
the fork loads and filters history using the active configuration.
- Verify that forking a legacy parent keeps the child in legacy history mode.
GitOrigin-RevId: 79416b78544467a1801f21300d3fe8db4fef59df
## What changed
- Track adjacent cells with the same OSC 8 destination and emit a single
hyperlink around their visible text.
- Close active hyperlinks before non-link content and at the end of a draw.
- Cover a production-length browser authentication URL at narrow terminal
width, including the remote-login guidance and cancellation footer.
GitOrigin-RevId: 9b87166ce78578137dfd2bf19db359ac83a908ee
## Why
Streamed message deltas can be dropped when the transport is saturated, leaving
clients with a truncated final response.
## What changed
- Include the last non-empty final agent message in successful `turn/completed`
notifications and mark the items as a summary.
- Treat completed message content as authoritative in the TUI, repairing an
incomplete stream while avoiding duplicate messages when `item/completed` was
already received.
- Continue backfilling full turn items for persisted `codex exec` threads when a
completion contains only the summary view.
## Testing
Added coverage for completion summaries, dropped stream deltas, duplicate item
handling, and directive-only responses.
GitOrigin-RevId: ffe9d36d683d6b6690e4a468ff68aa9189fe6ab7
## Why
Session header rows can exceed the available inner width when the terminal is
narrow, causing the bordered header to render wider than its requested width.
## What changed
Truncate each session header row to the available inner width and append an
ellipsis when content overflows.
## Testing
Add a snapshot test for a 44-column session header and assert that every
rendered line matches the requested width.
GitOrigin-RevId: 7cf0ea48aa95a6f1ddd1a9dbb7c7fb70bdbcb5a3
## What changed
Apply the existing whitespace-only line normalization to both streaming and
finalized agent Markdown. Blank lines now discard indentation and stale
hyperlinks while preserving their line style.
GitOrigin-RevId: f6150190b02f8cd8c853220cae1a2dcd2f4578a5
## What changed
- Size the unified mention popup from its filtered row count, while keeping a one-row minimum and the existing maximum.
- Update composer snapshots to cover the compact layout when only one mention result is visible.
GitOrigin-RevId: 7cd30a5c53c7e81cf7158a6b3dda3c09bd024f29
## What changed
- Let `exec-server` issue JSON-RPC requests to its client and correlate responses, with bounded concurrency, timeouts, and connection cleanup.
- When `request_policy_decisions` is enabled, forward proxy policy requests with the process ID and network destination, then apply the client's allow, deny, or ask decision.
- Fail closed for invalid inputs, unavailable or malformed responses, timeouts, process shutdown, and disconnects. Keep callbacks active while inherited process streams keep the proxy alive.
## Testing
- Cover response correlation, request limits, timeouts, disconnect cleanup, validation boundaries, decision forwarding, and process lifecycle behavior.
GitOrigin-RevId: 60e658102c50036589ca9de844760a8bffaa53b0
## What changed
- Add a `codex-git-attribution` context contributor that resolves the workspace's `commit_attribution_enabled` setting and supplies matching commit and pull request instructions through World State.
- Cache resolved policy by authentication generation, recover from unauthorized responses, and fail disabled on timeouts or settings errors with deferred retries.
- Handle enabled, disabled, and legacy attribution fragments so policy changes replace stale instructions without duplicating attribution.
## Testing
- Cover World State transitions, policy resolution after unauthorized responses, and authentication changes during an in-flight settings request.
GitOrigin-RevId: 6f733e708b5c960ba5e90751110910a03d1ba2df
## What changed
- Use `ClientRequest::method_name()` directly when preparing typed request
diagnostics for in-process and remote clients.
- Allocate the owned method name only when constructing an error.
- Remove the serialization-based method lookup and the redundant allocating
`ClientRequest::method()` helper.
GitOrigin-RevId: 93859e512a4f20204e0db4f929a2baebe4374ec5
## What changed
Treat `previous_response_not_found` websocket errors as retryable so Codex can
retry with the full request. Preserve the server-provided error message when
available, with a fallback message that explains the retry.
GitOrigin-RevId: 7fb6a1b4f396de561c491a16d793e2730b052f01
## What changed
- Decode `JSONRPCRequest` into `ClientRequest` without serializing the entire request back into an intermediate JSON value.
- Define every client method's wire name explicitly and use it directly for request, response, and tracing method lookups.
- Serialize outgoing transport messages directly to JSON strings instead of first building a `serde_json::Value`.
## Testing
- Add regression coverage that compares direct request conversion with Serde decoding, including omitted and null parameters, legacy methods, and unknown methods.
- Verify that direct outgoing-message serialization preserves the notification wire shape.
GitOrigin-RevId: 304e14bcaea24e32743bf852a60a208e2f273db3
## What changed
- Add the disabled-by-default, under-development `mcp_2026_07_28` feature.
- Include the feature in the configuration schema and app-server experimental
feature enablement API.
GitOrigin-RevId: 869835ee72f063d79ca2ecd9f2655d2efc457292
## Why
Core-compatible catalog rendering needs to preserve the core renderer's skill
priority, including when metadata budgets omit lower-priority entries.
## What changed
- Carry each host skill's `SkillScope` into its catalog entry.
- Under `CoreCompatible`, order visible skills by system, admin, repo, and user
scope, then by name and prompt resource ID.
- Preserve insertion order under `ExtensionCompatible`.
## Testing
Add coverage for propagating host skill scope and for both rendering policies.
GitOrigin-RevId: 9594a177edb2166abf1b5719c51a46fcee000600
## What changed
- Initialize the thread lifecycle input without an MCP resource client.
- Call `contribute_thread_context` without the removed step-scoped data argument.
GitOrigin-RevId: 689a982ba49c2788dde6bc2cbe0d6d7cae6c0a73
## What changed
When even the minimum skill catalog exceeds its metadata budget, render each
included entry without its description. This allows more skill names and
locators to fit before the remaining entries are omitted.
## Testing
Add coverage for extreme budget pressure and verify both the extension and
production-turn catalogs omit descriptions while staying within budget.
GitOrigin-RevId: 72cec10e9587beabbd3d8c6d53b931deb76824e6
## What changed
- Remove the step-scoped `ExtensionData` argument from context, turn-input, and tool contributors.
- Pass the host's optional `McpResourceClient` through `ThreadStartInput` so extensions can retain session capabilities explicitly.
- Keep the MCP resource client in skills-owned session state for catalog loading and skill tools.
