sayan-oai b43de77679 Scope environment readiness config to thread attachments (#38067)
## Why

Threads that share an executor environment can require different capability roots and login-shell policies. Treating readiness configuration as executor-wide can expose one thread's settings to another.

## What changed

- Add `CodexThread::environment_ready` and `EnvironmentConfig` so hosts can install capability roots and login-shell policy for an exact thread, environment, and working-directory attachment.
- Validate attachment readiness updates, merge ready attachment roots with persisted thread roots, and refresh MCP capabilities when those roots change.
- Preserve installed environment policy across thread settings updates and child-thread inheritance while resetting it when the selected working directory changes.

## Testing

- Cover attachment config inheritance and reset behavior.
- Verify that threads sharing an executor retain independent model-visible capability roots and login-shell tool schemas across updates.

rphilizaire-openai c8f673fddc Track resource-backed skill invocations (#38066)
## What changed

- Emit skill invocation analytics when a resource-backed skill is explicitly selected or its main resource is successfully read from the first page.
- Preserve provider-supplied skill IDs and user scope when available, and derive a stable ID from the main resource otherwise.
- Deduplicate repeated implicit reads of the same main resource within a turn.

## Testing

- Extend the orchestrator skill integration test to cover explicit and implicit invocation events, stable fallback IDs, failed reads, and repeated-read deduplication.

rka-oai 3a6f747d77 Preserve harness metadata across conversation history (#38058)
## 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.

edwardysun3 44d992c14e Track artifact operations from trusted plugin markers (#38057)
## What changed

- Recognize validated create and edit marker commands from the trusted presentations, documents, spreadsheets, and PDF plugins.
- Emit a `codex_artifact_operation` analytics event plus started-count and expected-output-count metrics when a recognized marker starts through unified exec.
- Attribute remote executor commands only when their plugin cache path and script contents match a trusted local plugin, including primary-runtime plugins.

## Testing

- Cover supported marker combinations and reject mismatched plugins, paths, arguments, counts, and output formats.
- Cover local, relocated remote, and Windows-style plugin attribution, including rejection of modified remote scripts.

## What changed

- Add `auto_review_enabled` to serialized turn metadata for regular and review turns.
- Derive the value from approval-policy routing and reserve the metadata key so client-provided metadata cannot override it.

## Testing

- Cover enabled metadata, reserved-key handling, Guardian review requests, and updated compaction request snapshots.

## What changed

- Add `ResponseItemEnvelope` as the history-owned wrapper for a `ResponseItem`.
- Store envelopes in `ContextManager` while keeping raw-item iteration and consuming APIs for existing callers.
- Preserve envelopes when compaction and history normalization rewrite retained items, and wrap newly synthesized items.

## Testing

- Cover envelope access, mutation, and conversion back to raw response items.
- Cover annotated history replacement and annotated user-message collection for compaction.

iceweasel-oai 34db7e5563 Sandbox remote apply_patch operations (#38043)
## Why

Cross-platform remote `apply_patch` calls were rejected when filesystem writes
were restricted because patch verification and writes could not be safely
performed against executor files.

## What changed

- Route intercepted and direct remote patches through the executor-managed
  filesystem sandbox, including the configured workspace roots.
- Select the restricted-token sandbox for Windows executor paths when no
  Windows sandbox level was configured.
- Fail closed when an executor cannot enforce the requested sandbox, and treat
  executor-managed access failures as sandbox denials so approval can retry the
  patch without sandboxing.

## Testing

- Cover sandboxed remote patches, denied writes, approval retries, Windows
  sandbox selection, and executor filesystem enforcement.

Bryan Ashley 722784e936 Distinguish turn-start thread persistence (#37926)
## 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.

- Consume operations directly in the submission loop instead of cloning them.
- Limit thread-manager test capture to the operation variants under test and update assertions to compare their relevant fields.

knittel-openai 9e301c8c9a Add configurable Responses API request metadata (#37895)
## What changed

- Add `responses_api_metadata` for product-owned key/value metadata included in
  every Responses API turn metadata payload, including parent and subagent
  requests.
- Limit the map to 16 entries, ASCII identifier keys of at most 64 bytes, and
  values of at most 128 bytes. Reject reserved Codex metadata keys and ignore
  this setting in project-local configuration.
- Give configured product metadata precedence over app-server client metadata
  while keeping it out of metadata sent to external MCP servers.

## Testing

- Cover reserved-key validation, metadata precedence, MCP isolation, and
  propagation to parent and subagent Responses API requests.

Adam Perry @ OpenAI 63002bdb26 Extract persisted history types into a dedicated crate (#37871)
## 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.

mchen-oai 4b0e2a0bff Support MCP form input in full-access user threads (#37864)
## 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.

Dylan Hurd d06dc73290 Route intercepted exec approvals through shared review (#37851)
## What changed

- Send Unix `execve` approvals intercepted by the zsh fork through the shared approval pipeline, including permission hooks, Guardian review, user prompts, and telemetry.
- Resolve the active turn and its auto-review setting when an intercepted command needs approval, so commands sent to persistent terminals use the current turn's reviewer.
- Give each intercepted command a distinct approval ID and propagate an aborted approval as a turn abort.

## Testing

- Cover Guardian review for intercepted `unified_exec` commands and persistent terminals across turns.
- Verify repeated identical intercepted commands receive separate user approvals.

Charlie Marsh 1c042dd4d8 Keep multi-workspace skill listings consistent (#37812)
## 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.

sayan-oai dd43a9967f Use step environments for Guardian approval reviews (#37618)
## Why

Deferred environments can become ready after a turn starts. Guardian approval
reviews must use the environment selected for the current step so their working
directory and permission context are not taken from the stale turn snapshot.

## What changed

- Carry `StepContext` through tool execution and approval handling.
- Add a Guardian review context that pairs the parent turn with the current
  step's environment snapshot.
- Use that snapshot for Guardian prompts, reviewer sessions, and delegated
  reviewer threads while retaining turn-level fallbacks for callers without a
  step context.

## Testing

Added an integration test that makes a deferred remote environment ready before
an escalated command and verifies Guardian receives that environment's working
directory and denied-read policy instead of the initial local environment's.

Abhinav 6f647caa9b Support asynchronous command hooks (#37533)
## Why

Hook configurations can mark command handlers as asynchronous, but Codex previously skipped those handlers outside `SessionEnd`.

## What changed

- Run asynchronous command hooks in the background with a per-session concurrency limit, while keeping `SessionEnd` hooks synchronous.
- Prevent asynchronous hooks from blocking, stopping, rewriting, or otherwise controlling the operation that launched them.
- Deliver warnings and additional context at safe turn boundaries: inject results into an active turn after sampling, or buffer them ahead of the next user prompt when the session is idle.
- Preserve in-flight hooks across configuration reloads, scope spilled output to the thread, and abort outstanding work during session shutdown.

## Testing

Add unit and integration coverage for background scheduling, concurrency, output parsing, active and idle result delivery, configuration reloads, and shutdown cleanup.

andrewgu-oai e734a1a5c1 Ignore reusable command approvals for cyber models (#37516)
## What changed

- Filter saved `allow` prefix rules from the execution policy for cyber-specialized models and models listed in `auto_review.ignore_rules`, while preserving prompt, forbidden, network, and host-executable policy entries.
- Apply the filtered policy consistently to permission instructions, shell commands, unified exec, and the zsh-fork backend.
- Limit cyber-model command approvals to one-time decisions without proposing reusable policy amendments. General models continue to honor saved prefixes, including after switching models within a thread.

## Testing

- Add policy-level coverage for filtering allow-prefix rules while retaining restrictive and network rules.
- Add end-to-end coverage across shell and unified exec paths, zsh-fork execution, user and automatic review, and model switching.

## 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.

## What changed

- Add `HostSkillsSnapshot::load_skill_prompts` so the skills extension owns reading and rendering selected host skills.
- Keep explicit invocation telemetry, unreadable-skill warnings, plugin prompt ordering, and suppression of host prompts superseded by provider prompts.
- Remove the legacy prompt injection and fragment implementation from `codex-core-skills`.

## Testing

- Cover prompt truncation without an installed skills extension, skill/plugin ordering, selective provider supersession, unreadable skills, and contextual fragment detection.

- 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.

## What changed

- Classify HTTP connection failures separately from other network errors without exposing request URLs.
- For sampling requests, retry connection failures with exponential delays from 5 to 60 seconds and show a `Reconnecting... waiting for network` stream error.
- Preserve the normal stream retry budget while waiting for the provider to become reachable. Keep the existing bounded retry behavior for other retryable errors.

## Testing

- Verify connection errors are classified without leaking URL contents.
- Verify a turn recovers after its provider becomes reachable and still applies the configured retry limit to a subsequent incomplete stream.

jif 964a227d8c Preserve base instruction provenance across sessions (#37446)
## Why

Persisted base instructions need to retain whether they were explicitly customized or generated from a model template. Without that distinction, forks and config-lock replays can treat model-generated instructions as custom and keep the wrong template after a model or personality change.

## What changed

- Record custom or model provenance with base instructions in rollouts and config locks.
- Preserve custom instructions across model changes, while allowing model-generated instructions to follow the selected model and personality.
- Keep legacy rollouts without provenance compatible and propagate provenance through forks and spawned agents.

## Testing

- Cover provenance serialization and legacy rollout decoding.
- Cover role personality changes, forked model changes, config-lock replay, and multi-agent configuration.

- Share plugin skill snapshots across those paths, preserving a consistent view of skills across workspaces.
- Apply migrated-command precedence after product filtering, allowing an eligible migrated command to replace a filtered native skill with the same name.

## Testing

- Add coverage for product-restricted plugin skills, native-versus-migrated command precedence, and the skills exposed to agent turns.

Boyang Niu 69b6152c17 Track context windows per agent (#37347)
## Why

Forked subagents can inherit a parent's compacted history, but their context-window metadata needs to identify the child and start a distinct window lineage.

## What changed

- Always identify context windows by agent name and remove the `features.token_budget.mode` setting.
- Persist the agent path in world state and emit context-window metadata as a standalone developer message when the identity changes.
- Reset inherited compaction metadata to the forked subagent's initial context window and restore that window in session state.

## Testing

Extend the full-history subagent test to verify parent and child world-state snapshots, agent identities, distinct window IDs, and the reset child checkpoint.

jif b3ffe3d001 Recover MCP servers after OAuth reauthentication (#37337)
## Why

An OAuth-backed Streamable HTTP MCP server can fail startup when its stored credentials are rejected. If a client then completes OAuth sign-in and replaces those credentials, the failed server needs to become available without restarting the Codex session.

## What changed

- Track the credential store and OAuth tokens used for each MCP connection, and detect replacements after authentication failures.
- Refresh affected MCP servers before the next turn and include their recovered tools in the model request.
- Classify HTTP authentication challenges and rejected refresh tokens as requiring reauthentication, with sign-in guidance appropriate to local and client-managed environments.

## Testing

- Cover recovery from expired credentials through an externally written replacement token.
- Cover authentication-error classification, startup messaging, and `Auto` store migration from file credentials to the keyring.

jif e1831db7c3 Reuse MCP handlers across sampling steps (#37273)
## Why

MCP tool handlers and their Code Mode definitions are immutable for the lifetime
of a stable MCP binding, so rebuilding them for every sampling step repeats schema
construction unnecessarily.

## What changed

- Cache MCP handlers per session and reuse them while the same binding remains
  active, invalidating the cache when the binding changes.
- Lazily cache schema-free Code Mode definitions on MCP handlers while continuing
  to rebuild definitions for step-local tools whose specifications may change.
- Reapply current app enablement, tool policy, exposure, and plugin schema budgets
  whenever cached handlers are registered for a step.

## Testing

- Cover handler and Code Mode definition reuse, binding invalidation, changing app
  policy, stable continuation schemas, and step-local custom tool updates.

jif 1151b23f01 Start cached MCP servers lazily for subagents (#37261)
## Why

Subagents can reuse cached MCP tool definitions without starting every optional
server before any of its tools are used.

## What changed

- Defer startup for subagent-owned, optional MCP servers when their cache has at
  least one visible, allowed tool, and trigger startup on the first operation
  that needs the live client.
- Keep root sessions, required servers, selected plugin servers, and explicit
  reconnects eager.
- Exclude empty catalogs from cache eligibility and keep dormant servers out of
  the initial startup summary.

## Testing

- Extend MCP tool-cache coverage for eager root startup, unused and filtered
  subagent servers, deferred startup status events, and startup that survives an
  interrupted first tool call.

jif a17da5e6e4 Fix first-turn model switching and rollback (#37260)
## Why

A model switch on the first turn has no prior turn settings to compare, and rolling that turn back could leave its model instructions in history.

## What changed

- Track the model that supplied the session's base instructions so first-turn switches inject the target model's instructions, including the selected personality.
- Preserve inherited custom base instructions when starting from an empty fork.
- Remove first-turn model-switch developer content during rollback so retries and cold resumes do not retain or duplicate stale instructions.

## Testing

Add integration coverage for first-turn switches, personality changes, empty-prefix forks, rollback retries, and cold resume.

Curtis 'Fjord' Hawthorne 0a0ebb8535 Add a unified image budget (#37206)
## What changed

- Add the gated `unified_image_budget` feature for models that support original image detail or Responses Lite.
- Apply one 6,000-pixel, 10,000-patch preprocessing limit regardless of legacy image detail hints.
- Hide detail controls from `view_image` and code mode while continuing to accept existing hints for compatibility.
- Preserve detail-based resizing and tool contracts for unsupported models.

## Testing

- Cover unified resizing limits, Responses Lite, legacy detail hints, unsupported models, and `view_image` integration in code mode.

efrazer-oai bc8b25ea02 Add durable user-message queue dispatch (#37204)
## What changed

- Add a storage-neutral queue extension for listing, adding, editing, reordering, deleting, and explicitly starting queued user messages.
- Dispatch queued messages in FIFO order when a thread becomes idle after a completed turn, while leaving them queued after interruptions or failures.
- Wait for user input to be persisted before removing its queue item, and report hook rejection, task termination, and persistence failures distinctly.
- Snapshot local image and audio attachments into validated data URLs before storing them, enforce input limits, and emit `ThreadQueueChanged` events after mutations.

## Testing

- Cover queue mutations, automatic and explicit dispatch, interruption and failure behavior, hook rejection, invalid records, input limits, and local attachment snapshotting.

Adam Perry @ OpenAI 92b83e226d Track multi-agent usage hints in world state (#37189)
## Why

Resumed sessions need the current multi-agent usage instructions when configuration changes or the saved history predates usage-hint tracking.

## What changed

- Store multi-agent usage hints in world state and refresh changed or previously untracked hints before re-emitting the active multi-agent mode.
- Present `wait_agent` polling guidance in the overridable developer instructions only when the tool is enabled, instead of embedding it in the tool schema.

## Testing

- Cover cold resumes, changes to `wait_agent` availability, custom usage hints, message ordering, and tool-schema behavior.

Rasmus Rygaard 15ea598c6e Expose session sources to MCP contributors (#37167)
## What changed

- Add `session_source()` to `McpServerContributionContext` for thread-scoped MCP resolution.
- Propagate each thread's `SessionSource` through initial setup, per-step resolution, and runtime refreshes.

## Testing

- Verify global contexts omit the source while thread-scoped contexts retain it.
- Verify MCP contributors observe distinct sources for a root thread and its spawned subagent.

felixxia-oai bd36d69aae Load host skill roots through the skills extension (#37162)
## What changed

- Load ordinary recursive host skill roots with the skills extension's host loader.
- Keep plugin-specific roots on the existing loader so plugin snapshot caching and namespacing continue to work.
- Merge both kinds of root snapshots through the existing precedence and deduplication logic, including discovery paths and source filesystem mappings.
- Move `HostSkillsSnapshot` into the skills extension as the owner of host skill loading.

## Testing

- Cover merged host and plugin catalogs, precedence for symlinked roots, discovery paths, and end-to-end rendering and invocation of host, repository, and plugin skills.

## What changed

- Add end-to-end coverage for a remote environment whose provisioning status is
  reported ready before it is selected for a turn.
- Verify that `wait_for_environment` makes remote execution tools and selected
  capability-root context available once the transport is ready.
- Update pending-environment and relay tests to cover separate materialization
  and readiness reporting, including deferred connection and reconnection.

rhan-oai 2b915a2eed Gate Apps usage instructions by model capability (#37145)
## What changed

- Add `include_apps_usage_instructions` to model metadata, defaulting to true for compatibility with existing metadata.
- Emit generic Apps guidance only when apps are available and the selected model enables it.
- Enable the capability for interactive model presets while leaving `codex-auto-review` and local models opted out.

## Testing

- Verify that missing metadata defaults to enabled and an explicit opt-out survives serialization.

xl-openai 72d937ed4d Preserve discovery paths for symlinked skills (#37144)
## Why

Symlinked skills have a canonical `SKILL.md` path that can differ from the path
under the configured skill root. A catalog entry that advertises the discovery
path must still select the canonical skill.

## What changed

- Track each loaded skill's discovery path alongside its canonical identity.
- Render discovery paths in the skill catalog and accept either form for
  structured selections and linked skill mentions.
- Preserve enabled-state checks, deduplication, and product filtering when
  resolving discovery paths.

## Testing

Added loader, catalog, mention-resolution, and end-to-end turn coverage for
skills discovered through directory symlinks.

Curtis 'Fjord' Hawthorne fa5d5ae047 Report prompt image resizing to the model (#37134)
## What changed

- Add the disabled-by-default `image_resize_notice` feature.
- When enabled, append a developer message after resized images from user
  messages or tool outputs. The notice identifies each image and reports its
  original and prepared dimensions.
- Persist notices with new history while avoiding backfilled notices for images
  processed when a session is resumed.

## Testing

- Cover notice placement, image numbering, failed images, user and tool image
  sources, and resumed-session replay.

Dylan Hurd 778b869829 Centralize tool approval handling in Session (#37128)
## What changed

- Move permission hooks, reviewer routing, approval caching, and user approval requests into the session-level approval flow.
- Have shell, unified exec, and apply-patch runtimes describe requests as `ApprovalAction` values, which now provide their hook payloads and cache keys.
- Pass a shared `ApprovalContext` through initial and retry approvals so telemetry and approval reasons are handled consistently.

sayan-oai ed2f985a26 Use turn environment permissions for context and discovery (#37040)
## What changed

- Build filesystem and permission context from the primary turn environment's permission profile, working directory, and workspace roots, falling back to the thread context when no primary environment is available.
- Build capability-discovery sandbox contexts from each environment's permission profile and treat discovery as restricted when any selected environment has restricted filesystem access.

## Testing

- Add regression tests covering environment-specific capability discovery and permission context updates.

sayan-oai bac3ef1d8e Use turn environment permissions for tool execution (#37038)
## What changed

- Derive sandboxing, approval, and permission-profile environment variables from the selected turn environment for shell, unified exec, `apply_patch`, image viewing, and network approval flows.
- Materialize project-root permissions against every workspace root in that environment, allowing `apply_patch` to write to secondary workspace roots while preserving protected paths.
- Carry the selected environment's permission profile into spawned or resumed agents and Guardian permission context.

## Testing

- Add an integration test covering `apply_patch` writes in a secondary workspace root.
- Extend tool, Guardian, and multi-agent tests to distinguish environment permissions from thread-level permissions.
