## Why
Creating the telemetry shutdown thread during shutdown can fail under resource
pressure, including when the native thread guard page cannot be allocated.
## What changed
- Start and verify a dedicated shutdown worker when `OtelProvider` is created.
- Send the provider to the prepared worker for bounded shutdown, while preserving
timeout behavior and avoiding a potentially blocking destructor if worker
preparation failed.
- Rename the fallible provider constructor to `try_new`.
## Testing
Add Unix regression coverage that injects guard-page allocation failures, plus
coverage for worker preparation failure, successful shutdown, and timeouts.
GitOrigin-RevId: 3656298078a800a7fa392437c2ee4a68753092e3
## What changed
- Probe the configured Responses inference endpoint with Codex's route-aware HTTP client, including configured proxy and custom CA behavior.
- Classify TLS, proxy authentication, proxy configuration, resolution, and timeout failures into actionable diagnostics.
- Report privacy-safe macOS system proxy state and suggest enabling `respect_system_proxy` when a configured proxy is otherwise unused.
- Preserve system-root fallback when a custom CA is invalid, and account for provider-specific API key configuration when selecting the probe route.
## Testing
- Cover inference endpoint selection, invalid custom CA fallback, proxy authentication failures, TLS classification, and macOS proxy reporting.
GitOrigin-RevId: c30a3ca5a332119e2b2f8c65341ef9b2251a28a2
## Why
Callers need to associate host-owned state with a thread before Core starts it.
## What changed
- Add `ThreadManager::reserve_thread_id` and allow new threads to start with the reserved ID. Reject reserved IDs when resuming an existing thread.
- Let thread stores stage metadata for a reserved ID. The local store merges staged values into the first successful metadata update and then removes them.
- Clear staged metadata when an unmaterialized thread shuts down or is discarded, and require the state database for staging.
## Testing
- Cover reserved ID generation and resume validation.
- Cover metadata persistence, merging, rollout-compatible updates, cleanup, and invalid staging requests.
GitOrigin-RevId: 3f9bc48f0f7764011cc90ea01349e497dda0a9e3
## What changed
Remove the unused `codex-cli` dev-dependency and the no-op import that kept it
visible to `cargo-shear`. TUI tests continue to locate spawned binaries through
`codex-utils-cargo-bin`.
GitOrigin-RevId: ba5855590c6f0300845170f15f39d77c0611a60a
## Why
Terminal probes and other bootstrap work can leave keys or partial control
sequences buffered before an interactive startup screen is visible. Those
inputs must not accidentally select or confirm an action, while typeahead
intended for the composer should survive terminal initialization.
## What changed
- Replay user input consumed by Unix startup probes through Crossterm while
filtering completed terminal color replies, and avoid consuming the Windows
console input queue when detecting default colors.
- Drain decoded and unread input after rendering actionable startup screens,
including onboarding trust, migration, update, provider, resume, and hooks
prompts. Keep incomplete control sequences quarantined and fail closed when
an input boundary cannot be resolved.
- Restore terminal modes if initialization exits early and bound terminal probe
reads by time and byte limits.
## Testing
Add parser, boundary, onboarding, and PTY coverage for preserved typeahead,
split escape sequences, bracketed paste, delayed input, and fresh input after
an interactive screen becomes ready.
GitOrigin-RevId: 321198996cdd88fe9b43c4a762e750bff450482c
## What changed
- Add `codex-guardian-v2` to the app server's dependencies.
- Install its feature-gated thread, approval-review, and tool lifecycle contributors with access to authentication and thread management.
GitOrigin-RevId: 25672032ccb541138c8c87c9f27f2a7423b2eee0
## What changed
- Register Guardian V2 for thread startup as well as tool-call lifecycle events.
- When `guardianv2` is enabled, create and store a thread-local Luna sampler using the thread's model provider, authentication policy, session metadata, originator, and service tier.
- Emit a warning if sampler initialization fails, and skip tool classification when the thread has no sampler.
## Testing
- Update the extension test to enable `guardianv2`, run thread startup, and verify tool-call sampling through the initialized connection.
GitOrigin-RevId: 5ab732e85c9827495c67f57117eb5be450a7f90e
## What changed
- Parse and validate the structured risk scores returned for each classified tool call.
- Publish each score through thread extension data and persist it in rollout history for non-ephemeral threads.
- Report parsing, thread lookup, validation, and persistence failures through the extension warning sink.
## Testing
- Extend the Guardian V2 tool-classification test to verify that the sampled `action_risk` score is available from thread extension data and written to rollout history.
GitOrigin-RevId: 46614fe0d686736dfb1f09398c6fcd848c7d8b2c
## What changed
- Add a `LunaSampler` that opens an authenticated Responses WebSocket and reuses it for structured, tool-free `gpt-5.6-luna` requests.
- Carry the host's provider, authentication, proxy, attribution, and service-tier configuration into the connection and requests.
- Require strict JSON schemas, preserve per-request reasoning effort and turn metadata, and reject missing or oversized output.
## Testing
- Add a WebSocket test covering authentication and attribution headers, connection reuse, structured request fields, per-turn metadata, reasoning effort, and returned output.
GitOrigin-RevId: aef85fd8ddcfcb7c76a9ede0d3191e3a0321656b
## Why
Streaming reads previously rejected requests that used a platform filesystem
sandbox.
## What changed
- Open streamed files in the sandbox helper and return the open file to the
exec-server by passing a file descriptor on Unix or duplicating a file handle
on Windows.
- Advertise support through the `sandboxedFileStreaming` environment capability.
- Preserve close-on-exec behavior for transferred descriptors, including the
required inherited-descriptor cleanup on macOS.
## Testing
- Cover bounded sandboxed streams, continued reads after path replacement, and
rejection of symlink escapes outside readable roots.
GitOrigin-RevId: 677b2444b74e834b78b87a8554bc119c1c6e08b2
## What changed
- Add the `codex-guardian-v2` crate with an extension install entry point that does not register contributors yet.
- Register the crate in the Cargo workspace and add its Bazel target.
GitOrigin-RevId: 7c0c9479c6722d65f0f0dad9b0fd4a756e4649b3
## What changed
- Resolve manifest-declared metric operations against the executor filesystem for remote plugin commands.
- Create the measurement sidecar in an executor-native, owner-private temporary directory, stream its bounded output back for validation, and clean up the directory afterward.
- Extend the exec-server protocol with the executor temporary directory and atomic private-directory creation.
## Testing
- Cover remote unified-exec measurements for foreground and background commands.
- Verify private directories use owner-only permissions on Unix and fail closed on unsupported platforms.
GitOrigin-RevId: dbbd0a84717b91237fc5728e510e18994eb46dd4
## What changed
- Add `TurnInputRequest` and typed submission results for atomically starting a turn, steering the active turn, or declining input with a specific reason.
- Expose `start_or_steer_turn`, `start_turn_if_idle`, and `steer_turn` on `CodexThread`, and migrate Core consumers to these APIs.
- Make app-server `turn/start` steer an active regular turn and return that turn's ID. Reject incompatible output schemas and non-steerable turns without applying settings or enqueueing input.
## Testing
- Cover concurrent start-or-steer submissions, accepted and rejected settings updates, output-schema compatibility, idle-start rejection, and app-server steering.
GitOrigin-RevId: dd9b5528d76ec650c019e97af420bc13190ea86a
## What changed
- Provide matching local plugin commands with a sandbox-writable temporary output file through `CODEX_PLUGIN_METRICS_OUTPUT` when analytics is enabled.
- Validate successful command output against the plugin's `analytics.yaml` declaration, including measurement names, enum dimensions, finite values, duplicate rows, and size limits, before publishing analytics events.
- Keep the output path reserved from user overrides and clean up the temporary file after execution.
## Testing
- Cover output validation, limits, cleanup, sandbox permissions, environment handling, and path replacement.
- Verify measurement collection through both classic and zsh-fork shell runtimes.
GitOrigin-RevId: 88af0f87dc2f207fcbcca6af498f5c940d79349d
## What changed
- Load version 1 `analytics.yaml` manifests from trusted plugin roots and map declared operations, measurements, and enum dimensions to exact script paths.
- Expose resolution types and bind a declared operation to the plugin identity returned by fresh command attribution.
- Reject malformed, oversized, ambiguous, or unsafe manifests without disabling normal script attribution.
## Testing
- Cover exact script resolution, measurement names shared across operations, and invalid manifests including duplicate keys, path traversal, symlink escapes, invalid identifiers, and oversized files.
GitOrigin-RevId: 1e2f221b9f2c3d7faffe578c7a8499ad4ed933ca
## What changed
- Select workload identity authentication from `OPENAI_FEDERATION_RULE_ID` and
`OPENAI_IDENTITY_TOKEN_FILE`, while preserving explicit API key and access
token precedence.
- Adapt workload identity exchanges to the shared authentication manager and
reuse a compatible process-scoped session for token resolution and refresh.
- Reject incomplete, conflicting, or unsupported configurations and exchanged
tokens that change the authenticated subject.
- Classify exchange failures for authentication retry handling and invalidate
rejected cached tokens without discarding a newer concurrent exchange.
## Testing
- Cover configuration selection and validation, session reuse and conflicts,
identity-preserving refreshes, concurrent refreshes, and retry classification.
GitOrigin-RevId: 62afb514b4e0a59effb08f464ac929633462a71b
## What changed
- Update the workspace `lru` requirement to `0.18.2`, consolidating consumers on a single version.
- Raise the `webbrowser` requirement to `1.2.2` and refresh the Cargo and Bazel lockfiles.
GitOrigin-RevId: c70dce42f4b6e0dc5567a28f778fd12c720d8f4c
## What changed
- Build URL-based gRPC code-mode connections with `HttpClientFactory` so they support the application's outbound proxy and custom CA configuration.
- Accept `http` and `https` origins while rejecting endpoints with unsupported schemes, paths, queries, or fragments.
- Preserve custom tonic channel injection and gRPC frame-size limits through the new transport adapter.
GitOrigin-RevId: 142f0b572b3ab0154e8fe860cb304752a9af5784
## What changed
- Subscribe each gRPC code-mode session to nested tool calls and forward tool and notification callbacks to its delegate.
- Complete tool calls through the host while bounding oversized results and errors.
- Track callback ownership and cancellation so completed cells drain notifications, terminated cells cancel them, and shutdown revokes outstanding work.
- Validate callback identifiers, cell ownership, enabled tools, and pending callback limits without serializing independent callbacks or sessions.
## Testing
- Add integration and state tests for callback forwarding, completion ordering, cancellation, malformed callbacks, delegate panics, oversized results, and concurrent work.
GitOrigin-RevId: 005afbb90eea0eb77d746b930a1a96ca6dfcd4e7
## 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.
GitOrigin-RevId: 7d8453b31b5a2205847e65cda2c46183d6c97b45
## What changed
- Add `GrpcCodeModeSessionProvider` for opening code-mode sessions over HTTP/2 or an existing `tonic` channel.
- Support execution, waiting, termination, per-session limits, cell-closure callbacks, and graceful shutdown over the gRPC protocol.
- Bound transport waits and error messages, validate host identifiers and responses, and clean up abandoned executions and observers.
## Testing
- Add end-to-end TCP tests covering session persistence, cancellation, concurrent waits, shutdown, cell cleanup, and independent yield limits.
- Add unit coverage for protocol conversion, deadlines, and session lifecycle state.
GitOrigin-RevId: d4729ce608ad4b42a99744b07e1f230e46cb24ec
## Why
Local stdio MCP servers may start in a different working directory from Codex,
so inherited relative CA bundle paths can otherwise resolve to the wrong file.
## What changed
- Forward the supported custom CA environment variables to local stdio MCP
servers, convert inherited non-empty paths to absolute paths, and let explicit
MCP environment overrides take precedence.
- Match CA variable names and `PATH` case-insensitively where required, avoiding
duplicate environment entries and preserving executable discovery on Windows.
## Testing
- Add an end-to-end stdio MCP test covering relative inherited CA paths, empty
values, explicit overrides, alternate key casing, and a different server
working directory.
- Exercise executable resolution with Windows-style `Path` casing.
GitOrigin-RevId: ea1bc0ae63bc0dc780acb8363b2ed102120f282e
## 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
## What changed
- Add `codex-build-info` to resolve a packaged runtime's semantic version from `codex-package.json` while preserving the commit stamped into the executable.
- Represent source builds as version `0.0.0` and expose helpers for display, serialization, and source-build detection.
- Stamp `STABLE_GIT_COMMIT` into final Bazel Rust binaries so Git changes do not invalidate the shared library graph.
## Testing
- Cover packaged, source, legacy, and invalid-version resolution, plus serialization round trips.
GitOrigin-RevId: 669b02449644c738ba2946a1b7aafe4ec31a9edb
## What changed
- Recognize executables under `codex-resources/` as part of a package layout by resolving the sibling `bin/` directory, while requiring that directory to exist.
- Add `InstallContext::package_manifest()` to parse the semantic package version from `codex-package.json`.
## Testing
- Extend the package-layout test fixture with a complete manifest and verify that version `1.2.3` is returned.
GitOrigin-RevId: 034aad3e8b865c6c6ecdff47da7c12c969744404
## 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
## What changed
- Add the `codex-workload-identity` crate for exchanging a file-backed JWT assertion and federation rule ID for short-lived ChatGPT credentials.
- Cache valid access tokens, refresh them before expiry or after rejection, and coalesce concurrent exchanges. Continue using a still-valid cached token when a proactive refresh fails transiently.
- Validate assertion files, token endpoints, and exchange responses; honor outbound proxy policy for HTTPS endpoints and redact access tokens from debug output.
## Testing
- Cover request encoding, assertion rotation, caching, concurrent refreshes, transient-failure fallback, configuration validation, and malformed inputs and responses.
GitOrigin-RevId: 5496851683c2dcf6aaad6840053b97f7c0be076e
## 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.
GitOrigin-RevId: 8094552e4afe7b47b09a61bb575bb20f4e491d8d
## What changed
- Export `GrpcCodeModeHost` as a transport-independent implementation of the
code-mode gRPC API.
- Support leased sessions, execution and wait lifecycle operations, filtered
nested tool-call subscriptions, tool completions, and notification
acknowledgements.
- Share host-wide request and active-cell limits across the existing and gRPC
transports, and bound identifiers, metadata, subscriptions, and pending
callbacks.
## Testing
- Add coverage for request conversion, ordered callback routing, cancellation,
session cleanup, backpressure, malformed input, and resource-limit handling.
GitOrigin-RevId: f146ba7e6fe4e4aa02f25dd3f961120980516d0e
## Why
Timing out a command hook can leave descendant processes running after the hook itself is stopped.
## What changed
- Run hook commands in a process group on Unix and a job object on Windows.
- Terminate the full process tree when hook execution is cancelled or fails, with `taskkill` as a Windows fallback.
- Preserve descendants when a hook completes successfully so intentionally detached helpers can continue running.
GitOrigin-RevId: 1a18653d34c6f1685ef8c4f8e8546663b276292a
## What changed
- Add the `codex.code_mode.v1` protobuf API for managing code-mode sessions, executions, waits, tool callbacks, notifications, and content results.
- Generate and export the Rust client/server bindings with `tonic` under Cargo.
- Add Bazel protobuf targets and a `prost` toolchain that uses the workspace's Rust runtime versions.
GitOrigin-RevId: 51d9d044e01dab2f4d25ab79aa7a52585485eee3
## What changed
- Move `SkillLoadOutcome` and its implicit-path indexing into
`codex-skills-extension`.
- Import shared skill types directly from `codex-skills` and keep the skill
prompt size limit with the extension renderer that uses it.
- Remove `codex-core-skills` from the Cargo workspace and dependent crates.
GitOrigin-RevId: 4e9e84909fa2f692bcc94af990bb4671affd776f
## 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.
GitOrigin-RevId: 9c8b84ad54b90d174abc287ab49cc5a231e9e1aa
## Why
High-volume request and streamed-response payloads can overwhelm the SQLite log database and diagnostic ring buffer used for reports.
## What changed
- Limit HTTP transport, SSE, and WebSocket diagnostics to `DEBUG` in persistent log sinks while leaving unrelated trace diagnostics available.
- Log known unhandled response events and delta events at `TRACE`, and surface unexpected event kinds at `DEBUG` without including their payloads.
- Report structured parse-error metadata instead of logging an unparseable SSE payload.
## Testing
- Cover filtering for transport, SSE, WebSocket, and unrelated trace records in both report and SQLite log sinks.
- Cover unknown and unsupported delta response events.
GitOrigin-RevId: 6d9121e093ddadf6834da394df544d9c09d8aeb9
## 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
- Define skill config selectors, ordered rules, and layer-stack parsing in `codex-config`.
- Resolve disabled skill paths from generic skill name/path pairs, so configuration logic no longer depends on `SkillMetadata`.
- Update plugin and host skill consumers to use the `codex-config` API and consolidate the rule tests with the skill config tests.
GitOrigin-RevId: 3fe67869708df2652befe28d58cdeba933256f84
## What changed
- Remove the unused `core-skills` client for listing and exporting remote
skills.
- Remove its `codex-core-skills` and `codex-core` exports and dependencies that
are no longer needed.
GitOrigin-RevId: 747f760dc97da3d4dea10d619a2341f43410d0bf
## What changed
- Use `HostSkillRoot` throughout host root resolution and loading, including plugin roots.
- Remove the duplicate loader, root snapshot, and product-filtering implementation from `core-skills` now that loading is owned by the skills extension.
- Move and expand loader coverage for discovery, namespaces, filesystem routing, root merging, symlinks, and frontmatter parsing.
## Testing
- Added focused unit and integration tests under `ext/skills` and `skills` for the consolidated loader behavior.
GitOrigin-RevId: 214d06d59bf3033ee0f220ea5959ee4feff66782
## What changed
- Add a `codex-diagnostics` crate that snapshots the process ID, available
resident-memory measurements, and registered process-wide gauges.
- Provide guards that update gauges for the lifetime of measured objects.
- Track live `CodexThread` instances with the `core.threads.live` gauge.
## Testing
- Add unit coverage for gauge registration, guard lifetimes, process memory
snapshots, and live-thread reporting.
GitOrigin-RevId: 3236b086bd4ebe31ed4768ab87a5fa288b0891b0
## What changed
- Add the `environmentConfig/read` RPC for selecting literal TOML paths from executor-local config and requirements layers.
- Return layer precedence, cloud insertion points, source and base-directory metadata, and executor home and hostname context without normalizing path-bearing values.
- Expose the operation through both remote clients and local `Environment` instances, with invalid selectors reported as invalid parameters.
## Testing
- Cover projected remote config reads and rejection of empty selectors.
GitOrigin-RevId: fee15bf833de6bcb2058d405ed5b1d5d928d7218
## 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
Converting each environment's working directory to a host-native path caused
turn-input contributors to omit environments with foreign path formats.
## What changed
- Expose `TurnInputEnvironment.cwd` as a `PathUri`.
- Pass every turn environment to contributors without host-path conversion.
## Testing
Added an integration test that submits a foreign working-directory URI and
verifies the contributor receives the environment unchanged.
GitOrigin-RevId: a122526be47f5331614381e9c6e4b85087a96bed
## 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.
GitOrigin-RevId: 14f39d7c8cbaccb767a6da84b82cced0edfcb4b9
## 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
## What changed
- Move tool mention parsing, skill-name counting, and implicit invocation detection into `codex-skills` and expose them through its public API.
- Decouple implicit invocation detection from `SkillLoadOutcome` with an `ImplicitSkillLookup` trait, while preserving the existing `core-skills` interface through re-exports.
- Cover remote plugin attribution for both implicit `SKILL.md` reads and skill script runs.
GitOrigin-RevId: f3da85c9821868638ccfd2fc2e01e0869d2fd437
## What changed
- Move the integration test for reusing plugin-manager skill snapshots into
`codex-core`, which owns both the plugin manager and host skills service
integration.
- Keep the `codex-core-plugins` test focused on resolving local and remote
plugin identities on effective skill roots, and remove its skills-extension
dev dependency.
- Use the skills extension's `HostSkillsSnapshot` type in its world-state
catalog implementation.
## Testing
- Verify the host skills service reuses the plugin manager's parsed snapshot
after the underlying skill file changes, while preserving plugin identity
metadata.
GitOrigin-RevId: afc8a0ebccb629360c59a4546bdb9a134c74da4f
## 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.
