## What changed
Derive code-mode tool names directly from registered tool names when checking
eligibility and collisions. Skip unsupported and empty tool specs explicitly,
without serializing schemas or augmenting descriptions that are not used during
executor registration.
GitOrigin-RevId: b439327aafd85ce3745d900301b7e48b56dbd6b4
## What changed
- Allow up to five seconds for focus-triggered input to appear in the PTY test.
- Check for unexpected foreground and background palette queries while waiting for both immediate and delayed input, so either focus path fails with the palette-specific error.
GitOrigin-RevId: b8ed4f1ced257865140b1518c8959f65371e744f
## What changed
Move shell snapshot validation in the intercepted `apply_patch` test until after
the turn completes and its patch lifecycle events have been collected.
GitOrigin-RevId: 1c16bcfcc97f09165c4a2eb2d15f4059a14b2a99
## What changed
- Route verified patches from both direct tool calls and intercepted shell commands through a shared execution helper.
- Simplify patch safety preparation to return either a runtime invocation or a rejection directly.
- Keep permission resolution, approval handling, event emission, runtime execution, and diff tracking in the common path.
GitOrigin-RevId: e16aae8e91d96b8108aefac7f3fbf2da2cbac016
## What changed
Make `ExtensionRegistryBuilder` wrap an `ExtensionRegistry` and register
contributors directly on it. Return the wrapped registry from `build()` instead
of copying each field into a new value.
GitOrigin-RevId: ae04de99c17ea951156f9892151b4196c70026bf
## What changed
Replace the type-erased `FragmentRegistration` trait and proxy objects with a
static list of `matches_text` function pointers. Remove the registration types
and their re-exports while preserving the existing contextual fragment matchers.
GitOrigin-RevId: 4e5a296b278984c6e783a67f48fa4bb37646946b
## What changed
- Store each turn's host skills snapshot in `ExtensionData` and expose it through
`TurnContext::skills_snapshot`.
- Lazily keep implicit skill invocation deduplication state in the same turn-scoped
store.
- Carry the skills snapshot into review turns without a separate
`TurnSkillsContext` field.
GitOrigin-RevId: d71579b5d230bd0b5f3c2ad062861f74d614d88c
## What changed
- Share argument normalization, server selection, cursor validation, and pagination setup between `list_mcp_resources` and `list_mcp_resource_templates`.
- Use a generic server-tagged wrapper to build single-server and deterministically sorted all-server payloads for both resources and templates.
## Testing
- Cover shared argument normalization and sorted resource-template payload serialization.
GitOrigin-RevId: 3505e4c1d2b95d8bbbb01f6f930fb914309eb898
## What changed
- Increase the listener, stream read, and overall test timeouts from 2 to 10 seconds.
- Switch the accepted stream back to blocking mode before reading the request.
GitOrigin-RevId: 1e876350421d7791194e145751603c4d709c7d39
## What changed
- Emit dynamic tool-call analytics for code mode `exec` and `wait` calls, including duration and terminal status.
- Associate code-mode cells and their nested tool calls with the originating and subsequent model response IDs.
- Buffer correlated tool events until the next response is known, while flushing pending events when turns, threads, or the analytics queue close.
## Testing
- Add reducer coverage for correlating `exec`, `wait`, and nested tool events across turns.
- Add an app-server test that verifies production analytics include the cell and response IDs for a code-mode `exec` call.
GitOrigin-RevId: 8b34ab59c1ad68ebbd57f9c8a05f19ab04df48a4
## What changed
- Store synchronization primitives directly in `TurnMetadataState` instead of
wrapping each field in its own `Arc`.
- Require an `Arc<TurnMetadataState>` when spawning Git enrichment so the
background task retains the complete state.
- Update Git enrichment tests to use the shared state container.
GitOrigin-RevId: 745ca6504c0a6533cb7726d045905472e51726df
## What changed
- Add a shared runner for MCP resource operation lifecycle events, output serialization, truncation, timing, and error handling.
- Use it for listing resources, listing resource templates, and reading resources.
GitOrigin-RevId: 84cae2e01a096d5b8ed97ea1cb462f01fe2ed1f9
## What changed
- Charge `codex_rollout_budget_units` against the shared rollout budget when the provider includes it in response usage.
- Fall back to weighted input and output token accounting when provider units are absent.
- Reject non-finite or negative provider units as a fatal response error.
## Testing
- Cover provider units in reminder thresholds and local and remote compaction budget exhaustion.
- Verify invalid units fail without retrying the response.
GitOrigin-RevId: b452403e365985854d16f298d1ba46383e9892c4
## What changed
- Parse `codex_rollout_budget_units` from completed Responses API usage into
`TokenUsage`.
- Keep the provider-only value out of serialized protocol, JSON schema, and
TypeScript representations.
## Testing
- Cover the value in unit and end-to-end SSE response parsing tests.
GitOrigin-RevId: a53d4202beb9c8985d25894cb10e7c01f20b2a44
## What changed
- Accept the allowlisted `.onboarding_entrypoint=life_sciences` suffix on a valid OAuth state while continuing to reject unknown or malformed suffixes.
- Return the parsed callback metadata from the login server without including the suffix in the token exchange redirect URI.
- Add the optional `onboardingEntrypoint` field and `life_sciences` value to the v2 `account/login/completed` notification and generated protocol exports.
## Testing
- Cover valid, invalid, and repeated OAuth state suffixes.
- Verify the end-to-end login callback result, token redirect URI, and app-server notification payload.
GitOrigin-RevId: c2ee146328ddd43c03a503260d5d492e186fa889
## Why
Setting or clearing a thread goal could reconcile an already indexed rollout and overwrite SQLite-only thread metadata, including the thread preview.
## What changed
Skip rollout reconciliation when SQLite already references the same existing rollout and its session metadata matches the requested thread. Continue reconciling when the SQLite row is missing or the stored rollout is invalid so goal mutations can still repair thread metadata.
## Testing
Add coverage that verifies goal set and clear preserve SQLite previews, and that goal set restores a deleted SQLite thread row.
GitOrigin-RevId: cf19cef98559fc67182ac7430e4e50ed2eed83f3
## Why
Agent Plugins use a schema-declared root `plugin.json` and can have dotted names or versions that do not fit Codex's directory-safe version format. The packaging and installation paths still assumed the legacy manifest layout and identifier rules.
## What changed
- Recognize valid root Agent Plugin manifests when discovering, packing, and installing plugins, while leaving unrelated root manifests on the legacy path.
- Accept safe dotted plugin names, default missing Agent Plugin versions to `1.0.0`, and derive stable directory-safe versions when necessary without rewriting the portable manifest.
- Skip legacy command migration for Agent Plugins and reject symlinks or other unsupported file types while copying plugin sources.
## Testing
Add coverage for portable bundle round trips, manifest discovery, dotted names, version handling, command preservation, and symlink rejection.
GitOrigin-RevId: 61476c4c4100495842253d8b429c0b896490962d
## What changed
Increase the maximum number of items collected across paginated MCP tool,
resource, and resource-template discovery requests from 1,024 to 2,048.
GitOrigin-RevId: b6ce0691d6a217e92faaf141cbf09978b296eeda
## What changed
- Accept two-stroke bindings such as `ctrl-x ctrl-s` in TUI keymap configuration while preserving arrays as alternative bindings.
- Route chords through the active TUI context, show pending and configured chord hints, and cancel pending chords on `esc`, context changes, or a one-second timeout.
- Extend `/keymap` to capture, add, replace, and display key chords.
- Reject chords that conflict with active single-key bindings, overlapping-context chords, or reserved terminal shortcuts.
## Testing
- Add coverage for chord parsing, validation, matching, timeout and cancellation behavior, context dispatch, key capture, and rendered shortcut hints.
GitOrigin-RevId: dfdede03f518d4936ad8621ebf5537026f2b282e
## What changed
- Reattach recorded `executed_tool_calls` metadata when an output is included in a subsequent prompt.
- Bound retained metadata to 32 KiB, prioritizing recent calls and reporting omitted calls in truncation metadata.
- Drop retained entries after their corresponding outputs leave the prompt history.
## Testing
- Cover metadata replay, cleanup after compaction, bounded retained history, and propagation through later tool requests.
GitOrigin-RevId: 1c23a26123be3b7ad51c61f4ad522139b71bb773
## What changed
- Raise the maximum remote plugin bundle download from 50 MiB to 100 MiB.
- Raise the maximum total extracted bundle size from 250 MiB to 512 MiB.
GitOrigin-RevId: 17ff4c256dd496afa7fd08d1e8e4cdbd40d49500
## What changed
- Carry dimensions on resize events and reuse the cached screen size for ordinary draws.
- Refresh terminal geometry after resize settling, process resume, and external program execution.
- Pass the resolved size through transcript reflow, viewport updates, and standalone TUI screens so each frame uses consistent dimensions.
## Testing
- Cover cached draws, resize-driven rendering, settled-size rechecks, resume refreshes, and alternate-screen size updates.
GitOrigin-RevId: 9d83dbab50d7a038bd59b4c66c13abcac69ddc79
## What changed
- Move JSON-RPC request, notification, response, error, and malformed-message handling into a dedicated `RequestDispatcher`.
- Keep the connection loop responsible for receiving events and closing the connection when dispatch reports a terminal condition.
## Testing
- Add an integration test confirming that ordinary requests are processed serially by default, including when a blocking `process/read` queues later requests.
GitOrigin-RevId: 29d1358d4524edd492ff3855b29f23c42c8b3390
## What changed
- Add the optional `delegationAckFiller` field to `thread/realtime/start`.
- Forward explicit `true` or `false` values to V3 Frameless Bidi session payloads as `delegation.ack_filler`; leave the field absent when unspecified so the Realtime API default is preserved.
- Document that V1 and V2 ignore this setting.
## Testing
- Cover both boolean values in Frameless Bidi serialization and verify the WebRTC V3 session creation payload.
GitOrigin-RevId: 9fe8efd14e42738c3e86e3e9a8af81d0f4521244
## What changed
- Run `git init` to mark command execution in the affected pre-tool hook tests.
- Keep marker repositories in per-test temporary directories and assert against
their `.git` directories.
- Check `git version` output when a code-mode hook rewrites a nested command.
GitOrigin-RevId: 71c54ef525b08e1d592f69c8b88eed1ee6403e4f
## Why
Clients need to know whether a `request_user_input` request must wait for an
explicit response or may auto-resolve. Using `autoResolutionMs` as that signal
conflated the blocking decision with timeout policy.
## What changed
- Add required `isBlocking` fields to user input protocol and app-server
request payloads. Plan-mode requests are blocking, while requests from other
enabled modes are non-blocking.
- Drive the TUI's auto-resolution behavior from `isBlocking` and remove
`autoResolutionMs` from the model-facing tool schema.
- Deprecate `autoResolutionMs` while retaining it for compatibility, and treat
legacy payloads without `isBlocking` as blocking.
## Testing
- Cover mode-derived blocking behavior, legacy deserialization, app-server
forwarding, delegated requests, and TUI auto-resolution.
GitOrigin-RevId: 29aade657ef743065ec264376ba567a9b353d7d7
## What changed
- Implement `plugin/search` by querying the remote plugin service without using the catalog cache.
- Support global, workspace, and personal scopes with bounded page sizes and passthrough cursors.
- Respect plugin feature gates and omit shared workspace results when plugin sharing is disabled.
- Keep search terms and pagination tokens out of transport errors and telemetry, and return search results as uninstalled plugin summaries.
## Testing
- Add remote search coverage for request parameters, result conversion, authentication, pagination, scope mapping, and error redaction.
- Add app-server coverage for remote-plugin and plugin-sharing feature gates.
GitOrigin-RevId: ac29c5480ed8089d998b6275bc5f11c8d9a43fd1
## What changed
- Add optional `realtimeStartInstructions` and `realtimeEndInstructions` fields to `thread/realtime/start`.
- Apply the instructions when Codex enters and leaves realtime mode, while preserving the existing defaults when either field is omitted.
- Limit each field to 8,192 estimated tokens.
## Testing
- Cover custom entry and exit instructions across realtime state transitions.
- Cover token-limit validation for both fields.
GitOrigin-RevId: b9cfa1ff22e084d8a6b2ed56bd27d95ffdd6b6bd
## What changed
- Add the experimental `plugin/search` request with search term, scope, working-directory, cursor, and limit parameters.
- Define paginated results that include each plugin's marketplace name and optional local marketplace path.
- Route the request through app server while returning method-not-found until the search implementation is available.
## Testing
- Add an app-server test that verifies `plugin/search` returns JSON-RPC error `-32601` with the expected not-implemented message.
GitOrigin-RevId: 755400468331f0887f7da7d933195c347aadf6d0
## What changed
- Load `environments.toml` in one operation, falling back to the default
environment provider only when the read reports that the file is missing.
- Attempt the default daemon socket connection directly instead of checking the
socket path first.
- Preserve each file search entry's type from the directory walker, avoiding a
second metadata lookup when producing matches and correctly classifying
followed directory symlinks.
- Write atomic-file contents through the existing temporary-file handle rather
than reopening its path.
## Testing
- Add Unix coverage for classifying a followed directory symlink as a
directory in file search results.
GitOrigin-RevId: aa6739cac23953ca8b9a3fcb53e43e72c41cfdf9
## Why
Legacy thread histories did not use the cross-process writer ownership guard already applied to paginated histories.
## What changed
- Acquire and retain a writer lock whenever a legacy or paginated thread is created or resumed.
- Apply the same ownership checks when archiving or deleting either history mode.
- Release ownership when initialization fails or the active thread shuts down, allowing another process to resume it.
## Testing
- Cover competing create and resume operations for both history modes.
- Cover archive and deletion conflicts for legacy and paginated descendants.
GitOrigin-RevId: 1be79b01966ad2634ed79eb96c0aa0db8eafe2fa
## What changed
- Record the effective detail setting and source and prepared dimensions for
successfully decoded images.
- Associate message images with their role and tool-output images with their
originating call ID.
- Include the collected image preparation metadata in the corresponding turn
analytics event.
## Testing
- Cover image resize metadata, tool-output attribution, turn aggregation, event
serialization, and app-server analytics output.
GitOrigin-RevId: dbfb5ba1ce7cb02dd93d9b579c5109817f16aef5
## What changed
- Add `CodexThread::submit_user_input_and_wait_for_admission` and export the
`UserMessageAdmission` result through `codex-core-api`.
- Resolve submissions only after they start a new turn or steer the active
turn, returning the accepting turn ID in either case.
- Return errors for invalid operations, rejected thread settings, and session
termination instead of leaving admission waiters unresolved.
## Testing
Add integration coverage for concurrent start-and-steer submissions, settings
rejection and recovery, non-user operations, and submission after shutdown.
GitOrigin-RevId: 21f1ede38d399baa9836d61a59b9f9af2dbf83b8
## Why
Loading the summary view issued a separate item query for every returned turn.
## What changed
Join each turn's first user and final agent items into the paginated turn query
when `StoredTurnItemsView::Summary` is requested. Preserve the existing fallback
that resolves inherited summary items for synthetic fork-boundary rows.
GitOrigin-RevId: add7f2e03c0809bbee85dc9f07bb6f91af92dfe7
## What changed
- Add `threadSection/create`, `threadSection/update`, and `threadSection/delete` app-server methods, with generated protocol schemas and TypeScript bindings.
- Persist custom sections in SQLite with stable UUIDv7 identities, trim and validate display names, and prevent renaming or deleting the built-in pinned section.
- Delete sections transactionally and return their active and archived threads to the unsectioned list.
- Serialize section mutations with section listing so concurrent requests observe ordered updates.
## Testing
- Cover section persistence across restarts, ordered renames, member cleanup on deletion, invalid requests, unsupported stores, and thread-store/state-runtime behavior.
GitOrigin-RevId: dc9a4be283c21dbc93ab1829eafc4825d8df6575
## What changed
- Start local resume and fork picker listings from indexed state DB metadata, while preserving the existing store-backed behavior for remote workspaces.
- Keep the selected listing mode across pagination and fall back to the normal local store listing when the initial state DB request returns no rows or fails.
- Add coverage for pagination, fallback rendering, and selecting an indexed thread without validating its rollout file.
GitOrigin-RevId: 9005fbe73134e261bc6dd3f588c4fff494bdeea0
## Why
Code mode must link against a V8 build with sandbox support, but Windows MSVC
still used upstream non-sandboxed prebuilts and package builds selected the
older release artifact profile.
## What changed
- Enable the `v8_enable_sandbox` feature directly for the code mode runtime.
- Select the `ptrcomp_sandbox_release` archive and bindings in Cargo packaging
and CI, including Windows MSVC release builds.
- Point Bazel's Windows MSVC targets at the sandbox-enabled Codex artifacts and
enable the matching crate feature.
## Testing
Add a runtime test that calls `v8__V8__IsSandboxEnabled()` and verifies that
the linked V8 library has sandbox support enabled.
GitOrigin-RevId: c1b49b44a6ccfea5b5006d69ec7866848d1cddd7
## What changed
- Add `--approve-for-me` to interactive and exec commands to route approval requests through automatic review.
- Configure the mode with `approval_policy="on-request"` and the `workspace-write` sandbox.
- Propagate the option across root, `exec`, `resume`, and `fork` argument handling while preserving later subcommand permission overrides.
## Testing
- Cover parsing, permission conflicts, root/subcommand precedence, resume handling, and the effective exec approval and sandbox modes.
GitOrigin-RevId: ae969e8c18f925f943049fefff56255f10b25659
## What changed
- Target `x86_64-pc-windows-msvc` in the post-merge native Windows Bazel job.
- Select the `//:windows_x86_64_msvc` target platform and the MSVC host platform.
- Update the job and execution-log artifact names to identify the MSVC target.
GitOrigin-RevId: ca7d65c8bc074dccb5e7ebbac3be80b97545a846
## Why
`ToolExecutor::exposure()` describes a tool's preferred exposure, while the host
may apply step-specific policy when building a tool plan.
## What changed
- Store each runtime together with its effective exposure in `ToolRegistry`.
- Apply MCP, namespace, and collaboration-tool exposure overrides directly to
registry entries instead of wrapping runtimes.
- Use the registry-owned exposure when building model-visible specs, deferred
tool search, code-mode executors, and parallel-call support.
## Testing
- Cover that a hidden MCP tool remains routable but is not eligible for parallel
tool calls.
GitOrigin-RevId: 1bc2760add8d993f477954269fa13681bfcc2444
## What changed
- Recognize the `codex_strict_auto_review` MCP elicitation marker and route
marked approval requests through the configured automatic reviewer.
- Accept only canonical automatic-review approvals and fail closed without a
user prompt when review is unavailable, denied, malformed, disallowed by
policy, or requests persistence.
- Validate Codex Apps approval metadata against the active MCP invocation and
build the review request from the trusted invocation details.
## Testing
- Add unit coverage for strict review decisions, malformed markers, reviewer
failures, explicit policy denials, and lifecycle cleanup.
- Add app-server round-trip coverage for approvals, denials, configuration
constraints, spoofed metadata, persistent requests, and subsequent turns.
GitOrigin-RevId: af73b45a9b63118f25f6429d95b3222c5dbb59fb
## What changed
- Make the skills extension own the catalog prompt templates and rendering path.
- Remove the duplicate core fallback that injected available skills into initial context.
- Update core integration tests to install the skills extension explicitly when they expect model-visible skill context.
GitOrigin-RevId: bbe6b15c4e776a09c98b7f4166426fe4e58434ba
## What changed
- Discover and import home-level Cursor skills from both `skills` and
`skills-cursor`.
- Keep repository-level Cursor migration scoped to `skills`.
- Deduplicate skill names when reporting migration candidates from multiple
source directories.
## Testing
- Add coverage for detecting and importing user and Cursor-managed skills.
- Verify repository detection continues to use the `skills` directory.
GitOrigin-RevId: 7b5e96a0d9c5ca14c61230e336728f2e4930a3b0
## What changed
- Read the frozen MCP tool catalog directly from the step-scoped `McpBinding`
when building tool routers, plugin injections, and connector state.
- Remove the redundant `Vec<ToolInfo>` from `StepContext` and stop returning a
duplicate catalog from `built_tools`.
GitOrigin-RevId: d12d694e1224da3f6ccb1960868491f0d80c6e19
## What changed
- Route skill dependency updates through the shared `codex-core` `ConfigEditsBuilder`.
- Remove the duplicate MCP config writer and its tests from `codex-config`, while retaining MCP config loading there.
GitOrigin-RevId: cdce84c8353514529126156750433e859b78be3b
## Why
Tool calls can outlive the sampling request that advertised them, so execution
must retain the finalized tool plan for that specific step.
## What changed
- Resolve tool runtimes, parallelism, cancellation behavior, argument diff
consumers, and dispatch from the `ToolRouter` stored in `StepContext`.
- Remove the separate router parameter from `ToolCallRuntime` and code-mode
worker construction so callers cannot supply a different router.
- Add a test helper for installing a router into a test `StepContext`.
GitOrigin-RevId: 9e476ddd228ca5b1c03ed87863618ba77de6200c
## Why
External agent session files can gain messages after their initial import. Re-importing those files should extend the existing Codex thread instead of creating a duplicate.
## What changed
- Map a changed source session back to its uniquely imported thread and append only the missing transcript suffix.
- Update the import ledger after verifying that the source and destination transcripts match.
- Defer the update when the target is active, archived, ambiguous, diverged, or otherwise unsafe to modify.
## Testing
Added unit and app-server coverage for suffix planning, ledger checkpointing, concurrent updates, and unsafe targets that must be deferred.
GitOrigin-RevId: 3d9e71cd66e8b31cf5128e8869063868bfb3eb05
## Why
Threads can configure the same MCP server name with different runtimes. Tool calls
must use the runtime associated with the thread that issued the call.
## What changed
- Route MCP readiness checks and call preparation through the invoking session.
- Add regression coverage that alternates calls between two threads and verifies
that each thread continues using its own MCP server process and configuration.
GitOrigin-RevId: 5735f7b29a579f545351385ab01a575e35ead01e
## What changed
- Replace `SessionTaskContext` with `Arc<Session>` in the session task run and abort interfaces.
- Read extension data from `TurnContext` during regular turns instead of storing and forwarding a duplicate reference through the running task.
GitOrigin-RevId: 04bc0d324e5ba781f35ac9c61e811888208b74ae
## What changed
- Add optional `default` and `plan` collaboration-mode messages to model catalog metadata.
- Prefer the active mode's catalog message, including an explicit empty value, while falling back to the existing developer instructions when the catalog variant is absent.
- Track the model in collaboration-mode world state so mode and model changes append the appropriate instructions, and clear prior instructions when no current message exists.
- Preserve catalog collaboration messages when instruction overrides remove other model instruction fields.
## Testing
- Cover catalog deserialization, variant selection, fallback and empty-message behavior, legacy snapshot migration, mode changes, and model changes.
GitOrigin-RevId: d4c6c0028423bc50b0e8175e55586f3e7bc1c3a8
