## What changed
- Use the standard automatic test environment for plugin list, install, and
uninstall app-server tests.
- Keep the bundled stdio MCP test host-local because its fixture is a local
executable.
- Strengthen that test to verify the bundled server initializes and exposes
its `echo` tool.
GitOrigin-RevId: 06dac135b0cc0b28fc235d95a02129eecf8f8c09
## What changed
- Add an embedded `defaults.toml` and always install it as the lowest-precedence configuration layer when no packaged-defaults path is supplied.
- Keep packaged defaults out of config RPC layer and origin metadata.
- Report a user setting as overridden only when the effective layer has higher precedence, so clearing a setting can fall back to its packaged default without a false override.
## Testing
- Cover loading the packaged layer when other configuration files are absent.
- Cover config RPC filtering and clearing a user value that falls back to a packaged default.

## Why
Executor skills required a `skills.list` lookup before their contents could be
read, even when the catalog already identified the skill.
## What changed
- Render executor skill catalog entries as package locators, including shortened
locators when skill roots are aliased.
- Tell the model to pass those packages directly to `skills.read`, while keeping
`skills.list` as the fallback when no package is available.
- Use the shorter package locators when applying the skills context budget.
## Testing
Update catalog, aliasing, budget-pressure, and selected-skill coverage, including
an executor package ID containing a literal backslash.
GitOrigin-RevId: 2ace5e527dc4f29651a8f3214475ccc90d52c73f
## What changed
- Make automatic MCP OAuth registration prefer Client ID Metadata Documents
(CIMD) when the authorization server advertises support for public clients and
Codex is using its native loopback callback. Fall back to advertised Dynamic
Client Registration (DCR) otherwise.
- Add explicit `cimd` and `dcr` registration overrides to the CLI and app-server
OAuth login API. Validate CIMD metadata and callback URLs before starting the
authorization flow.
- Use a callback-specific Codex client metadata URL for CIMD and retain the
exact redirect URI through authorization and token exchange.
## Testing
- Cover automatic and forced CIMD selection, DCR fallback, invalid metadata and
redirects, token refresh, authenticated MCP requests, and conformance
regression checks.
GitOrigin-RevId: 4238372ca53b0f38e781e141ab5da97e0a6ddf45
## What changed
- Wrap response items with optional harness-owned metadata while keeping the persisted response payload shape backward compatible.
- Store compacted-history metadata in an aligned sidecar and reject malformed sidecars.
- Carry metadata through history normalization, compaction, resume, fork, truncation, migration, and rollout recording without sending it to model providers.
## Testing
- Cover legacy rollout compatibility, metadata serialization and validation, compaction retention, and resume/fork reconstruction.
GitOrigin-RevId: 17a6127c9048ff984cb4df4d97c0751a38c29f5f
## What changed
- Add `--oauth-client-registration` with `auto` and `dcr` choices to `codex mcp add` and `codex mcp login`.
- Add the equivalent optional `clientRegistration` field to `mcpServer/oauth/login` and the generated protocol schemas.
- Keep automatic dynamic client registration as the default, prefer a configured OAuth client ID when present, and apply the selection only to the current login without persisting it in MCP configuration.
## Testing
- Cover dynamic registration and configured-client OAuth flows through the app server.
- Verify the CLI does not persist the per-login registration choice.
GitOrigin-RevId: 653a4a1054ff43c2c5d52ae863b6a96d21692a53
## What changed
- Add structured `usageLimitExceeded` metadata to failed image-generation
items, including the image limit ID and optional reset timestamp.
- Preserve the failure metadata in completion events, app-server thread
history, thread reads and resumes, and migrated legacy rollouts.
- Export the new failure type in the generated JSON and TypeScript schemas.
## Testing
- Cover usage-limit responses through item completion, persistence, and thread
resume.
- Verify legacy rollout migration retains image-generation failure metadata.
GitOrigin-RevId: 91c31a2a47456b6b916ee03002ff314b05946dd4
## Why
`skills/list` can load multiple working directories in one request, but bundled
skill discovery did not account for different effective configurations across
those directories.
## What changed
- Resolve `skills.bundled.enabled` from each load input's effective config layer
stack inside the host skills service.
- Include or exclude system-scoped skills for each working directory based on
that resolved setting.
- Keep bundled skills enabled by default when the setting is absent or invalid.
## Testing
- Add a multi-directory `skills/list` test with bundled skills disabled in one
project and enabled in another.
- Add config-layer tests for defaults, overrides, and malformed bundled-skill
configuration.
GitOrigin-RevId: e4e97dc7d0a374ac71d0aa11e55a9e337f661717
## What changed
- Add `PersistContext` to the thread-store persistence contract so stores can
identify persistence requested immediately before model sampling. A
`TurnStart` request may be enqueued in the background when later flush and
shutdown operations fence it and report any failure; all other persistence
remains synchronous.
- Use the turn-start context only for the initial input of a regular turn, while
admission acknowledgments, steered input, and other persistence paths keep
the standard durability behavior.
- Flush pending metadata before turn-start persistence and ensure shutdown is
still attempted if that metadata update fails.
## Testing
- Verify that developer instructions and user input are persisted before the
model request completes for a default paginated-history thread.
GitOrigin-RevId: 162f0ec796a61aebe66ca0b909fbcccec3047b85
## What changed
- Add optional `icon` and `color` appearance fields to custom thread sections and expose them through the app-server protocol.
- Persist appearance metadata in SQLite and include it when listing sections or returning threads.
- Let `threadSection/update` preserve an omitted appearance, clear it with `null`, or replace it with a new value.
- Reject appearance fields larger than 64 bytes.
## Testing
- Cover protocol compatibility, persistence across restart, update and clear behavior, and field-length validation.
GitOrigin-RevId: 8f55ce4f42f8bd17aa5416848a85845f681953df
## What changed
- Add an optional `threadId` parameter to `app/read`.
- When provided, load the thread's effective configuration before applying app feature gating, workspace policy, and plugin attribution.
- Share the thread-aware configuration loader with `app/list`.
## Testing
- Add coverage showing that `app/read` honors a thread-level connector feature override.
GitOrigin-RevId: 161e910a2d7435ecf4acd0ba9f5f5069d1631f12
## What changed
- Add `goals.max_goal_token_budget` as a positive-integer configuration setting.
- Use the configured maximum as the default budget for new goals and when `tokenBudget` is reset to `null`.
- Reject goal creation and updates whose token budget exceeds the configured maximum, including requests through goal tools and `thread/goal/set`.
- Respect managed configuration precedence and per-thread configuration overrides.
## Testing
- Cover configuration parsing and managed overrides.
- Cover defaulting, resetting, and rejecting oversized budgets through the goal service, goal tools, and app-server API.
GitOrigin-RevId: f8d7e6418cdc237d454c8cf47bb32ba0d44a60cf
## What changed
- Add `codex-history` for model-history and persisted-rollout domain types, including `RolloutItem`, `RolloutLine`, `CompactedItem`, and initial/resumed history state.
- Re-export the persisted types from `codex-rollout` and update consumers to use the new crate boundary instead of `codex-protocol`.
- Preserve existing rollout serialization, including legacy numeric compacted-window IDs.
## Testing
- Add `codex-history` tests for rollout JSON round trips, compacted-history compatibility, persisted history modes, and multi-agent version selection.
GitOrigin-RevId: 944daa9297ddd231d3aebbdcb05fff4adf8b4e1b
## Why
Standard MCP forms can require user-entered values even when tool permissions are
otherwise auto-approved in full-access sessions.
## What changed
- Recognize the `openai/standard-form-input` client extension and surface
non-approval forms in full-access, user-initiated root threads.
- Keep approval forms, automation and subagent threads, headless sessions, and
clients without the capability on their existing decline or review paths.
- Treat the capability as client-only so it is not advertised to MCP servers,
and enable it after session startup so required servers cannot block startup
waiting for form input.
## Testing
Add unit and app-server coverage for accepted form round trips, declined cases,
approval metadata safeguards, resumed threads, and extension filtering.
GitOrigin-RevId: 053bfe397a5c79eceef90a81d13e2aca6353af43
## What changed
- Add `pluginId` to each `mcpServerStatus/list` result.
- Populate it for MCP servers contributed by installed or selected plugins, and
return `null` for servers from other sources.
- Update the generated protocol schemas, TypeScript bindings, and app-server
documentation.
## Testing
- Cover plugin-owned servers in plugin installation and executor flows.
- Verify non-plugin servers and protocol serialization return a null
`pluginId`.
GitOrigin-RevId: 0e4b912252cf51be56dcb63e0c1c7365a5e870ee
## Why
A single `skills/list` request should use one view of shared skill roots across
all requested workspaces while still applying each workspace's skill rules.
## What changed
- Add a request-scoped host skills view that reuses non-plugin root snapshots
across `cwd` entries without persisting them across requests.
- Resolve user-scoped plugin skill roots once per request, then apply workspace
skill configuration separately for each `cwd`.
- Make `forceReload` refresh plugin roots before building the request-scoped
view so subsequent entries see the refreshed skills.
## Testing
Expanded `skills/list` and host skills service tests to cover multiple ordered
workspaces, per-workspace skill rules, request-local snapshots, cached results,
and forced plugin-root refreshes.
GitOrigin-RevId: eedd3a4c3e213b7f30df6cacd3adf23ba2967437
## What changed
- Make `package` the only required argument to `skills.read`, resolving the
owning orchestrator or executor catalog automatically.
- Default omitted `resource` values to the package's main `SKILL.md`.
- Render orchestrator skills as package locators and instruct the model to read
them directly without first calling `skills.list`.
- Update skill extension and app-server coverage for direct main-resource
reads, referenced resources, aliases, and the revised tool schema.
GitOrigin-RevId: 9faf57a8d0935566a15094931eaabaa8f0613e9e
## Why
Clients need to correlate a remote plugin installation request with a specific
installation attempt.
## What changed
- Add the optional `installAttemptId` field to `PluginInstallParams`.
- Forward the value as `install_attempt_id` in the remote plugin install POST
body.
- Preserve the existing empty request body when the field is omitted.
## Testing
- Cover protocol serialization and remote install request bodies with and
without an attempt ID.
GitOrigin-RevId: ffdceff4f9329b650848e6428a9ba39646c242c3
## What changed
- Add the `apply_patch_preserve_line_endings` feature, disabled by default, to
preserve CRLF, CR, and mixed line endings when `apply_patch` updates files.
- Apply the feature consistently to built-in patch handling and patches invoked
through shell, user-shell, unified-exec, and app-server command execution.
- Keep the active feature configuration authoritative over inherited, shell
snapshot, and client-provided environment values.
## Testing
- Cover line-ending behavior with the feature enabled and disabled for custom
tool calls, shell heredocs, command execution, and the `apply_patch` CLI.
GitOrigin-RevId: 531a7c66761959c650270559f57941929f03e6c4
## Why
Resolving the working directory encoded in a Cursor project name could recursively scan large directory trees.
## What changed
- Probe a bounded set of path candidates using common filename separators instead of walking the directory tree.
- Stop after 128 probes and reject ambiguous matches or unsafe encoded components.
- Parse Windows drive prefixes separately from the encoded path.
## Testing
Added coverage for common separators, ambiguous leaf and ancestor paths, and Windows drive prefixes.
GitOrigin-RevId: 34b2a2bbe2d302fac3d2614a5e36dd3fa20cf2e5
## What changed
- Append a stable `std::io::ErrorKind` category to the
`failed_to_load_session_config` subtype, including categories such as
`invalid_data`, `not_found`, and `permission_denied`.
- Propagate the categorized subtype through session import failure reporting.
## Testing
- Add an app-server test that verifies an invalid config reports
`failed_to_load_session_config_invalid_data` in both the import completion
notification and analytics event.
GitOrigin-RevId: e9a1a7cd36979911f422805180dd91b6ed65e14e
## Why
Plugin install failures need stable, low-cardinality details that distinguish
actionable causes without relying on error messages.
## What changed
- Add HTTP status subtypes for remote catalog, mutation, and bundle download
failures, including specific common statuses and a general `http_5xx` bucket.
- Emit failure analytics when a remote plugin is disabled by an administrator or
unavailable under its install policy.
- Preserve marketplace I/O, configuration, and task failure subtypes, including
failures that occur before a plugin ID can be resolved.
## Testing
Add app-server coverage for catalog and install HTTP failures, unavailable
remote plugins, unreadable marketplace files, and oversized bundle error
responses.
GitOrigin-RevId: 71a4888c492d1806bf4ff92bebc48f40cfb89300
## Why
Model-reachable child processes should not inherit Codex launch context.
## What changed
- Treat `OPENAI_FEDERATION_RULE_ID` and `OPENAI_IDENTITY_TOKEN_FILE` as non-inheritable environment variables, with case-insensitive matching.
- Remove them after shell environment policy overrides and before spawning commands across execution, MCP, hooks, Git helpers, and remote helper processes.
## Testing
- Cover inherited and explicitly configured variants, including mixed-case names.
- Verify the variables are absent from real child environments and app-server command and process execution.
GitOrigin-RevId: 2535527893985fef0995617f4c5b2462bea7c136
## What changed
- Add `executionMode` to `HookMetadata` returned by `hooks/list`, with `sync` as the default for compatibility.
- Propagate each discovered hook's `sync` or `async` mode through the app-server protocol and generated schemas.
- Show the execution mode in the TUI hooks browser.
## Testing
- Cover async and default-sync modes in `hooks/list` tests and TUI snapshots.
GitOrigin-RevId: 9c9f2890798fe417face76c15847616b2dea9db4
## Why
External agent detection can spend time reading session transcripts. Sharing the
configuration serialization queue causes unrelated configuration requests to
wait for detection to finish.
## What changed
- Give `externalAgentConfig/detect` its own global serialization queue.
- Keep configuration reads, requirements reads, writes, and external agent
imports responsive while detection is still running.
## Testing
Add a Unix app-server test that blocks transcript detection on a FIFO and
verifies the unrelated requests complete before detection is released.
GitOrigin-RevId: d2764dcdb0e96d810c790c570c48fa45690a3dc1
## What changed
- Add the managed `auto_review.required_on_models` requirement, unioning model slugs across requirement layers and exposing the result through `configRequirements/read`.
- Force listed models to use `on-request` approvals with the `auto_review` reviewer. Downgrade Full Access to workspace-write when starting a protected session, and reject incompatible runtime overrides or use when automatic review is disabled.
- Preserve these protections across thread starts, resumes, forks, model changes, turn overrides, MCP approvals, and TUI session attachment.
## Testing
- Add coverage for layered model requirements and exact provider-alias matching.
- Add app-server tests for protected thread lifecycle operations, unsafe setting overrides, legacy thread upgrades, disabled automatic review, and requirements API output.
GitOrigin-RevId: c4b1d52c3b5b75e86880725412b8f0812e0dfcd9
## Why
Long executor and orchestrator resource identifiers can consume enough of the
skills context budget to omit otherwise available skills.
## What changed
- Add source-aware root aliases for executor, orchestrator, and host skill
catalogs, including catalogs with a single shared root.
- Select the best combination of aliased catalogs under the shared metadata
budget while accounting for root tables and alias usage instructions.
- Explain how to expand shortened `skill://` locators and accept the resulting
description-shortening warning in app-server coverage.
## Testing
- Add rendering and production-turn coverage for singleton, executor,
orchestrator, host, and combined catalog aliases.
GitOrigin-RevId: c1bc1f3d371eae9526232674060235272cc28f16
## What changed
- Add lifecycle-backed gauges for in-flight and queued app requests, pending server requests and mailbox messages, active turns, and live MCP connections.
- Register each gauge on first use and decrement it when the tracked work or resource is dropped.
- Document the new `server/diagnostics` gauge names and account for the diagnostics request itself in the response example and test.
GitOrigin-RevId: 4bb82a3918af0b502d149b5d761ad669b2083f39
## What changed
- Add the experimental `server/diagnostics` request, returning the app-server process ID, resident memory, platform-dependent physical footprint, and registered diagnostic gauges.
- Export the new protocol types in the generated JSON and TypeScript schemas and document the request.
## Testing
- Verify the response includes process measurements and the registered live-thread gauge.
- Verify the request is rejected unless `capabilities.experimentalApi` is enabled.
GitOrigin-RevId: 099d60a9c421a74ff1a72fe524e0dfeb89cf1057
## What changed
- Route plugin inventory loading and capability summaries through the injected
`SkillRootLoader`.
- Preserve recursive discovery for legacy plugins while restricting agent-plugin
skill discovery to direct children of the skills root.
## Testing
- Verify `plugin/read` excludes nested agent-plugin skills.
- Verify installed agent-plugin telemetry reports skills only for portable,
direct-child layouts.
GitOrigin-RevId: 9e78dd0c70a632d510c780963a6ceb3ad4bc2522
## What changed
- Add nullable `multiAgentVersion` metadata to v2 `model/list` responses.
- Represent supported values as `disabled`, `v1`, or `v2` in the Rust API and generated JSON Schema and TypeScript exports.
- Forward the value from model catalog presets through app-server responses.
## Testing
- Extend the remote model catalog test fixture with a `v2` multi-agent version.
GitOrigin-RevId: bd3b2bbe0a3b562b4d1f03df7da2a73a35713978
## What changed
- On cold `thread/resume`, restore the latest approval policy from persisted
thread settings instead of falling back to the current configured default.
- Preserve the precedence of an explicit request override over the persisted
policy.
- Account for settings applied during a turn when the subsequent compacted turn
context contains a stale policy.
## Testing
- Add unit coverage for selecting the latest persisted policy.
- Add app-server tests for legacy and paginated history, including explicit
resume overrides.
GitOrigin-RevId: 9127a3c53a90f16d67957ded9e7430e79180fc60
## What changed
- Parse `mcp_tool` hook handlers with a server, tool, JSON input, and optional timeout and status message.
- Return managed MCP tool hooks from `configRequirements/read` and include the handler in the generated protocol schemas.
- Skip MCP tool hooks during discovery with an explicit warning until execution is supported.
## Testing
- Cover MCP tool hook deserialization, including nested and null JSON input values.
- Extend the config requirements RPC test to verify the new handler shape.
GitOrigin-RevId: ff7e2d12b75b486c54d63469af547a29f9b31418
## What changed
- Add `codex migrate-rollouts` with dry-run inspection by default, explicit `--apply`, thread filtering, optional I/O throttling, progress output, and JSON or verbose reports.
- Add the disabled-by-default `background_paginated_rollout_migration` feature to migrate legacy local sessions at startup before rollout compression begins.
- Persist a migration cursor and skipped-file fingerprints so later startups avoid full rescans while retrying changed files and recovering pending migrations.
- Coordinate migration with live writers and emit metrics for manual and startup runs.
## Testing
- Cover startup cursor advancement and lookback, pending migration recovery, live-writer coordination, changed empty rollouts, and progress reporting.
GitOrigin-RevId: 276ac506c50ebec5140fd319faca1bb998172061
## Why
An account change can select different OpenTelemetry collector settings. The
long-running app server needs to stop exporting telemetry with the previous
account's configuration.
## What changed
- Rebuild and install the log, trace, and metrics exporters when authentication
changes, and shut down the previous provider without blocking the app server.
- Make cached global metrics clients and the tracing layer follow the replacement
provider so existing callers continue exporting through the current account's
configuration.
- Clear the cached cloud configuration loader after login and logout so telemetry
reloads from the new account context.
## Testing
- Add an app-server integration test that switches accounts and verifies logs,
traces, and metrics reach the new collector while trace context is preserved.
- Add a metrics test covering cached clients after provider replacement.
GitOrigin-RevId: a74359777a35edbee5bbe0b2baccc155074cb172
## Why
Multi-agent v2 rejected `agent_type` when `fork_turns` was `all`, forcing callers to choose between a configured role and the parent's full conversation context.
## What changed
- Apply an explicitly selected role to full-history forks, including its model and developer instructions.
- Preserve the parent's developer instructions when the selected role does not define its own.
- Keep the inherited conversation history and model-switch context intact.
- Update the `spawn_agent` schema to clarify that roles apply independently of history inheritance.
## Testing
- Cover full-history role overrides and developer-instruction precedence in multi-agent v2 tests.
GitOrigin-RevId: cd4f35e31d75f56289760f245bff38dd0233abe6
## What changed
- Fetch the paginated installed-plugin snapshot without a `scope` query instead of issuing separate requests for global, user, and workspace plugins.
- Use the combined snapshot for installed-plugin caching and bundle synchronization while continuing to reconcile each scope's marketplace independently.
## Testing
- Cover pagination across mixed scopes, request query parameters, marketplace reconciliation, stale cache cleanup, and discoverable-plugin filtering.
GitOrigin-RevId: 7428a9db81d7ec04e65cc4b236b652278b200956
## What changed
- Emit `codex_thread_archive_event` when a thread is successfully archived or
unarchived, including the thread ID, action, and producer timestamp.
- Route archive notifications through the analytics client while preserving
normal app-server notification delivery.
## Testing
- Extend app-server coverage for archive and unarchive analytics, including
descendant archives and a repeated archive request that fails without
producing another event.
GitOrigin-RevId: 0d973c232fd795b7cd6cddd47ecc9446234c44dd
## Why
The `cwd` recorded in a rollout can become stale after thread metadata is
updated, causing thread reads and lists to disagree with the persisted state.
## What changed
- Overlay a non-empty state database `cwd` when reading a thread by ID.
- Apply the same overlay when reading by rollout path, but only when the
metadata points to the requested rollout.
- Recompute the permission profile against the selected `cwd` and continue to
fall back to rollout metadata when the persisted `cwd` is empty or belongs to
another rollout.
## Testing
- Cover stale, empty, and mismatched persisted `cwd` metadata.
- Verify that `thread/read`, state-only `thread/list`, and `thread/resume`
report the persisted thread `cwd` while the resumed session uses its requested
live `cwd`.
GitOrigin-RevId: 50a3f187618ee3cadbad95196ee2976e2d5e9a5a
## What changed
- Add a Guardian circuit-breaker policy for models whose catalog specialty is
`cyber`.
- Interrupt those models after the first Guardian denial while retaining the
existing denial thresholds for other models.
- Centralize the `cyber` model-specialty identifier for use across core,
protocol, app-server, and TUI code.
## Testing
- Cover the cyber-specific threshold in the circuit-breaker unit tests.
- Verify end to end that a denied command is not executed and the turn is
interrupted after one denial.
GitOrigin-RevId: fad24c9e7aa280432580db1f0e39d13535779710
## What changed
- Add `transparentBackground` to image-generation items and legacy completion events.
- Map Images API backgrounds to `true` for transparent, `false` for opaque, and `null` for automatic or unavailable values.
- Preserve the metadata in live notifications and persisted or resumed thread history while continuing to deserialize older items that omit it.
## Testing
- Cover transparent, opaque, and automatic backgrounds, including image edits and thread read/resume flows.
- Verify the stable JSON shape and optional TypeScript field.
GitOrigin-RevId: 08527f37f23431df45fab1ed34eb82b2139b49d7
## What changed
- Add `LocalThreadStore::migrate_rollouts` with dry-run and apply modes,
optional thread selection, throughput limiting, and per-rollout outcomes.
- Canonicalize legacy JSONL records into paginated history while preserving
model-visible conversation context, including compressed rollouts and copied
fork history.
- Publish replacements atomically and journal migrations so interrupted SQLite
projections can be recovered. Coordinate migration with rollout compression
and skip rollouts with active writers.
- Make paginated history a one-way SQLite promotion so stale metadata cannot
downgrade a migrated thread.
## Testing
- Cover legacy record normalization, dry runs, idempotency, malformed input,
compressed rollouts, active writers, interrupted migration recovery, and a
cold app-server resume after migration.
GitOrigin-RevId: b9991b659f28ebb52da39ce62e8b4e0bae2ba2bb
## Why
Authentication restrictions must apply before stored or environment-provided credentials can be used, including during bootstrap before cloud requirements are fetched.
## What changed
- Add local `requirements.toml` allowlists for login methods and ChatGPT workspaces. Ignore these fields in cloud-provided requirements.
- Combine managed workspace allowlists with existing workspace restrictions by intersection, and fail closed when the resulting policy permits no usable login method.
- Centralize policy checks in the authentication manager so CLI, TUI, app-server, external-auth, and credential-loading paths consistently reject disallowed authentication before token hydration or network requests.
## Testing
- Cover policy composition, workspace intersection, invalid stored and external credentials, bootstrap enforcement, and login endpoint restrictions.
GitOrigin-RevId: efef22b248f3c3333e9aa55423e539efa2d2dd48
## What changed
- Propagate the optional `modelSpecialty` field through the model catalog and
app-server `model/list` response.
- When a newly selected model has the `cyber` specialty, default an active TUI
thread to workspace-write permissions with on-request approval. Use auto
review when available, otherwise keep the user as reviewer, while respecting
configured permission requirements.
- Show a notice when auto review is applied and strengthen the full-access
warning for cyber models.
- Preserve explicitly selected permissions when only reasoning settings change.
## Testing
- Cover auto-review defaults, requirement-aware fallback behavior, permission
preservation across reasoning changes, and the new warning notice.
GitOrigin-RevId: 8f25b0082d3051d9ff91f7355921236d0f82f758
## What changed
- Track Agent Plugin manifests through plugin, skill, and MCP loading so their capabilities use format-specific behavior without changing legacy plugins.
- Discover only direct-child skills, exclude app and hook capabilities, isolate MCP data, and reject MCP configuration files that are non-regular or resolve outside the plugin root.
- Bound model-visible skill instructions, plugin instructions, MCP descriptions, schemas, individual tools, and the aggregate Agent Plugin MCP tool set.
- Stop MCP and OAuth redirects when Agent Plugins send configured or authorization headers, while retaining existing redirect behavior for legacy MCP servers.
## Testing
- Add coverage for capability filtering, skill discovery, isolated MCP data and reserved-path expansion, unsafe MCP configuration files, context limits, and redirect handling.
GitOrigin-RevId: c9af66b051269f3226628ca280a58d32c808c38f
## What changed
- Key cached skill snapshots by filesystem and plugin snapshot identity so compatible config and working-directory loads can share results without reusing stale plugin data.
- Coalesce concurrent loads for the same cache key and replace the cached entry on forced reload.
- Clear both plugin and skill caches when `skills/list` forces a reload, and bypass working-directory caching when effective plugin roots are present.
## Testing
- Cover concurrent cache sharing, filesystem isolation, forced reloads, and refreshed plugin skill metadata in host service and app server tests.

## Why
Clients using `thread/read` with `includeTurns: true` need the legacy full-history
view even when a thread stores its history in paginated form.
## What changed
- Reconstruct full projected turns from paginated history for both stored and
loaded threads.
- Keep `thread/turns/list` and `thread/items/list` as the preferred incremental
history APIs.
## Testing
- Cover `thread/read(includeTurns=true)` before and after a paginated thread is
loaded.

## Why
The bundled system-skill cache is shared by every process using the same
`CODEX_HOME`. A service with bundled skills disabled must not remove cache
files that another service still uses.
## What changed
- Filter system skill roots from disabled services without deleting the shared
cache.
- Ensure bundled system skills are installed during loads when they are
enabled, including after a runtime configuration change.
## Testing
Add app-server coverage for preserving the cache across enabled and disabled
services and refreshing stale cached skills after runtime enablement.
