## What changed
- Represent MCP tool calls as approval actions and route them through the
session-level approval flow for permission hooks, reviewer selection,
rejection handling, and resolution telemetry.
- Preserve MCP-specific user prompts, session and persistent approval choices,
and the approval policy and reviewer captured for the tool call.
## Testing
- Add coverage for permission hooks resolving MCP calls before user or
automatic review, persistence choices, captured policy routing, and MCP turn
metadata with strict automatic review enabled.
GitOrigin-RevId: 8e134b3d17a19dc62b3b56076d2cd05a54c9f638
## What changed
- Include the connector ID, action name, and model in file creation requests for hosted app tool calls.
- Use the file size returned by upload finalization when available, while falling back to the local size for older server responses.
- Keep upload finalization requests empty for compatibility with older servers.
## Testing
- Cover hosted app upload metadata and legacy finalization responses.
GitOrigin-RevId: 1bc834736db4fe3515f8224965cde0e5d6955ca3
## What changed
- Resolve user message admission when Core accepts the input as a new turn or a steer, without waiting for rollout persistence.
- Remove persistence- and hook-specific admission errors and task bookkeeping.
- Delete queued messages after Core accepts them for turn processing, including messages subsequently stopped by a prompt hook.
## Testing
- Update concurrent admission and queue service tests for acceptance-based admission.
GitOrigin-RevId: 7dcc311cfecd3d710733b420f2add546edb86153
## What changed
- Permit immediate user-message admission to start a turn when `Op::UserInput`
has no items. The turn can proceed with its generated environment context and
does not emit a user-message item.
- Continue rejecting empty input for persisted admission, where there is no
user message to persist.
## Testing
- Cover successful empty-input turn admission and completion.
- Cover prompt rejection of empty persisted admission.
GitOrigin-RevId: d534cf0e228e3bc77f45fe6d9bd25c9073216fbd
## What changed
- Add `ApprovedMcpPolicyAmendment` to represent MCP approvals that persist across sessions.
- Route MCP approval responses directly through the shared `ReviewDecision` type while preserving session-only approvals, rejection reasons, timeouts, and cancellations.
- Reject the MCP-only policy decision if it reaches command, shell, network, or other tool approval paths.
## Testing
- Update MCP approval parsing, normalization, hook, and Guardian tests for the shared decisions.
- Verify generic tool approvals reject MCP policy amendments.
GitOrigin-RevId: b8cc931dc61d4c794915145273ede82b9eb30fc8
## What changed
- Deserialize typed section snapshots directly from borrowed JSON values.
- Build and apply world-state merge patches in place instead of cloning and converting entire snapshots.
- Preserve the existing snapshot when a top-level patch has an invalid shape.
## Testing
- Extend the world-state merge-patch test to cover invalid top-level patches and verify that they leave the snapshot unchanged.
GitOrigin-RevId: 6c2212587b025a8dc3878008a0466d4526eee204
## What changed
- Detect executor-owned skill document reads and script executions across native and URI-based working directories.
- Match skills only within the active execution environment while preserving host skill detection for local commands.
- Emit resource-backed implicit invocation events and deduplicate repeated accesses within a turn.
## Testing
- Add unit coverage for document reads, script executions, and environment-scoped matching.
- Add an integration test for environment selection, resource-backed analytics, and repeated-access deduplication.
GitOrigin-RevId: f78a48c3a4766fe8775bd88926b45a76761f6af8
## 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.
GitOrigin-RevId: 60e7a296b3e41b835b0413aa2837451e8a55c230
## 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
- Set `store` to `false` for every Responses request, including requests sent
through Azure providers.
- Remove the provider-specific storage check and simplify request construction.
- Update the Azure request test to verify that storage is disabled while
prefixed item IDs remain unchanged.
GitOrigin-RevId: 1c71cb80880058cb26789112f03269b73f0645b9
## 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
- 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.
GitOrigin-RevId: 475cc1689aa7f371a24dec0a8bdb6f7fd5a2e922
## What changed
- Add the under-development `psp` feature and expose it in the config schema.
- Use the feature to attach the PSP cookie to first-party ChatGPT clients.
- Remove the hidden `--psp` flag and its process-scoped configuration plumbing.
- Preserve configured ChatGPT cookies when creating the PSP client used for GET and POST requests.
## Testing
- Update the config manager service test to verify that enabling `features.psp` retains the setting in the effective config and configures the expected ChatGPT cookie.
GitOrigin-RevId: 53acb5495d2ff71e4ed25f674a0cff787aea474a
## 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 `inject_response_items_for_turn` for callers that inject Responses API
items immediately before admitting user input. It defers the rollout flush so
the injected items and user input are persisted together by turn admission.
- Keep `inject_response_items` behavior unchanged by flushing after it delegates
to the new helper.
- Update the turn-start persistence test to exercise the turn-aware path.
GitOrigin-RevId: 8349b65f937af2b2a95d36b3fd73d862d38e5fd9
## 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.
GitOrigin-RevId: 52773e2bf7d4be251f8466332de9f9c9869dd084
## 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.
GitOrigin-RevId: 3fa2e7bdd981b08cc7aec410c80deccaecdabab4
## 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.
GitOrigin-RevId: caddeed0b266c456a689080a14a3a58e2bd7887c
## 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
- Remove effective-config lockfile export, replay, and validation from session startup.
- Remove the `debug.config_lockfile` settings and generated schema entries.
- Remove feature-config materialization helpers that were only used to create lockfiles.
GitOrigin-RevId: a8c07c1c06325b3ec3dae9a97c36c2488d37df25
## What changed
- Import skill metadata and mention helpers directly from `codex-skills`.
- Import host skill loading types directly from `codex-skills-extension`.
- Make the remaining `codex-core` skills module private and remove its skill API re-exports, including the `HostSkillsService` re-export from `codex-core-api`.
GitOrigin-RevId: 26bf8fffd980df9c4d0c308d7e983ceab9a5df82
## 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
- Reject invalid or unsupported image data before producing tool output, so
non-image file contents are not exposed through code mode.
- Preserve valid image bytes and metadata while leaving image preparation and
resizing to the history insertion path.
## Testing
- Cover invalid images in both code mode and standard `view_image` calls.
- Verify that code mode preserves PNG bytes, dimensions, EXIF orientation, and
metadata.
GitOrigin-RevId: 07343ed10b781d0ce0ffb5b24432658be4c046e3
## 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
- Pass image bytes from `view_image` through unchanged for both direct and code-mode calls, leaving decoding and resizing to the shared history-insertion path.
- Represent invalid image data with the existing image-omission placeholder instead of returning a tool error.
## Testing
- Update the `view_image` integration test to cover placeholder output for invalid image data.
GitOrigin-RevId: 62863defd4815efb8a7725712fd583ad81db3fbb
## What changed
- Remove `Clone` from `Submission` and remove `Clone` and `PartialEq` from `Op`.
- 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.
GitOrigin-RevId: 781cc631391b8583d94dad5ca45f589856c0b21a
## 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.
GitOrigin-RevId: a7be798294fde25145ab375a468321bb4e4a49f1
## What changed
- Decode image data in the `view_image` handler and return a clear error for invalid or unsupported input.
- Re-encode code-mode images as PNG pixel data while preserving original image bytes for direct tool calls.
- Cover code-mode PNG output and rejection of invalid image data.
GitOrigin-RevId: 0a00e595ab749c19eab866a22f6577b6627e19f1
## 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
## Why
Managed networking implicitly selected the elevated Windows sandbox backend,
even when the sandbox was configured to use a restricted token.
## What changed
- Select the Windows sandbox backend solely from `WindowsSandboxLevel`.
- Reject managed networking with a restricted-token sandbox before spawning a
process, since managed networking requires the elevated backend.
- Cover the rejection through sandbox preparation, unified exec, and Windows
sandbox session tests.
GitOrigin-RevId: 308858652d7b629af623d22896dafde3a23d3758
## 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
- Rename `EnvironmentConfig` to `TurnEnvironmentConfig` to make its scope explicit.
- Rename the corresponding `SessionConfiguration` accessor and update all call sites.
GitOrigin-RevId: f47d745566199e699bd8e7c671c313eaf3bba79e
## 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.
GitOrigin-RevId: e6cccf160637e4246aff4714c22f08c90b65306d
## What changed
- Set `CODEX_SESSION_ID` to the shared root-session ID for shell tool calls,
unified exec processes, and user shell commands.
- Preserve `CODEX_SESSION_ID` when restoring a shell snapshot, alongside the
existing runtime-owned environment variables.
GitOrigin-RevId: 5228867d25507105c7edf11607a8298958c3b917
## What changed
- Restore a V2 agent's inherited environment selections when reloading its
thread after residency eviction.
- Keep the restored execution environment and its tools available when the
agent receives a follow-up task.
## Testing
- Add an integration test that evicts and reloads a V2 agent, then verifies
its environment selection and `exec_command` tool are preserved.
GitOrigin-RevId: a5d4ad0fa465c717b32b7ae6807486429187a41d
## What changed
Add the `codex.turn.unified_exec.running_processes` counter and increment it
by the number of background terminal processes remaining when a turn finishes.
GitOrigin-RevId: 82a33b89533960d86cef95360fa122836c8aa84d
## 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
## Why
Building a prompt cloned every model-visible `ToolSpec`, even though the tool
set is immutable for the lifetime of its router.
## What changed
- Store model-visible tool specs as an `Arc<[ToolSpec]>` in `ToolRouter` and
`Prompt` so prompt construction only clones the shared pointer.
- Keep separately built routers on distinct shared slices so refreshed tool
sets remain independent.
## Testing
Extend router tests to verify allocation sharing within a router, allocation
separation across rebuilt routers, and the existing deferred-tool filtering.
GitOrigin-RevId: 1e04cd7c4d1b3fa0b494c5c51670232d38ba8ebb
## 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
## What changed
Read `allow_prefix_rules` from the turn attached to the active step context
when selecting the exec policy and constructing unified exec approval requests.
GitOrigin-RevId: d2d26e88b9cefa28bb2df5b9f71aa7b30b7ea331
## 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.
GitOrigin-RevId: 779096bc7d0e0c7453a009c02141029714b9b407
## 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
## 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
- 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.
GitOrigin-RevId: f3bd3872424291b12354ec415f33986ec369a368
## What changed
- Add the under-development `guardian_reuse_parent_compaction` feature.
- Restart Guardian review sessions after parent history rewrites and seed them with the latest encrypted compaction that has a response item ID.
- Keep the existing reviewer when a rewritten history has no reusable compaction, preserving authorization and restriction context held by that session.
## Testing
- Cover reuse-key invalidation and compaction eligibility.
- Verify review-session behavior across parent compaction and a subsequent summary-free history reset.
GitOrigin-RevId: 891805d3c3dca34ddda6e3bfc5097be4ff164267
## 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
## What changed
- Add the effective permission profile as `sandbox_mode` in turn metadata for regular, prewarm, compaction, and detached memory requests.
- Reserve `sandbox_mode` so client-provided metadata cannot override the computed value.
## Testing
- Cover metadata headers and request bodies for read-only and danger-full-access modes.
GitOrigin-RevId: 13c690cc99bc2691023f281ca527af049bb1286f
## 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
