## What changed
- Admit the curated remote Browser plugin's `Stop` and `SubagentStop` hooks when its listed `browser.turn_ended` tool matches the expected connector and is enabled by app policy.
- Carry trusted app routing metadata and the MCP environment through hook registration and execution.
- Register hooks from multiple executor environments, while deduplicating cleanup calls that share an event, MCP environment, server, and tool.
## Testing
- Cover Browser and Computer Use cleanup through separate MCP routes, including user- and managed-policy disablement.
- Verify routing metadata, environment selection, multi-environment registration, and target deduplication.
GitOrigin-RevId: 66de088fd201b9ed0db8b97c23d33de88135120d
## What changed
Allow bundled browser and computer-use plugins to invoke the existing
`node_repl.turn_ended` cleanup hook for `SubagentStop` events, matching the
allowlist behavior for `Stop` and `Interrupt` events.
GitOrigin-RevId: 0fe1784321e793e9861e728b40a48662625b7dca
## Why
Executor-scoped cleanup hooks need to observe an interrupted turn as well as a
normally completed one.
## What changed
- Allow bundled executor plugins to register the allowlisted `Interrupt` hook
alongside `Stop`, while preserving multiple allowed hook entries from the
selected executor environment.
- Run interrupt hooks with the interrupted turn's last step discovery and turn
metadata. Turns without a step context do not reuse discovery from an earlier
turn.
- Keep executor-scoped interrupt hooks asynchronous and omit public hook
lifecycle events for them, matching executor `Stop` hook behavior.
## Testing
Added coverage for hook filtering and registration, interrupt execution and
metadata propagation, environment selection, and turns without a step context.
GitOrigin-RevId: f0c536b3382a37cf3bf693c4573d21f6f66ace4e
## What changed
- Add a positive `output_token_limit` setting to each entry under an MCP server's `tools` configuration.
- Apply the most restrictive limit when plugin and user policies overlap, while keeping approval policy independent.
- Carry the effective MCP output budget in conversation history so tool output, post-tool hook responses, and resumed sessions use the same truncation limit.
## Testing
- Cover configuration parsing, serialization, schema validation, and plugin policy merging.
- Cover MCP output below and above the configured limit, post-tool hook responses, and session resume.
GitOrigin-RevId: d0beb4fca9ba6055d9e1d31c137373b465d50d61
## Why
Enabling, disabling, or reinstalling a cached remote plugin can change its
effective MCP servers, hooks, and skills without materializing a new bundle.
These transitions need to invalidate plugin consumers just like bundle updates
and removals do.
## What changed
- Report a unified set of changed remote plugins and their affected
capabilities for materializations, removals, and installed-state changes.
- Derive enablement and reinstall changes by comparing installed snapshots,
while keeping materialization metadata separate for hook trust handling.
- Preserve removal notifications even when stale cache cleanup fails, and use
all reported changes to refresh loaded plugin state and runtime consumers.
## Testing
Added coverage for cached plugin enablement, disablement, removal, and
reinstallation, including removal when cache cleanup cannot complete.
GitOrigin-RevId: 86d9c1356f7cf70b3c85effebc3e5986b931bdba
## Why
Fetching plugin recommendations while building the first-turn context delays that
context when the recommendation catalog is not already cached.
## What changed
- Start fetching recommendations during session initialization, in parallel with
MCP and plugin setup, and reuse the in-flight request when building context.
- Centralize the feature checks that enable plugin recommendations.
- Prevent an invalidated recommendation request from repopulating the cache after
a newer request has completed.
## Testing
Added coverage for startup feature gating, reuse of the in-flight fetch, legacy
behavior when recommendations are unavailable, and cache invalidation races.
GitOrigin-RevId: 708774b9bfc472c9847973ae8b2774b66e7321e4
## What changed
- Count loaded-plugin cache requests by `hit`, `hit_after_wait`, or `load` outcome.
- Record time spent waiting for the load semaphore and loading plugins.
- Count cache clears and capacity evictions.
- Remove the unused force-reload path from `PluginsManager::plugins_for_config`.
GitOrigin-RevId: db7829e7bd9b1414a263d9a7100c05dfdd832777
## What changed
Apply the legacy plugin app/MCP routing policy even when no authentication mode is available. Unauthenticated plugin reads now omit unavailable app declarations while retaining their MCP server alternatives.
## Testing
Extend plugin manager coverage for unauthenticated reads and provide ChatGPT authentication in the app-server bundle-details test.
GitOrigin-RevId: d90d29d0702488eb7413c6779254a9e6aae615c0
## What changed
- Load the effective plugin configuration for every requested `cwd` in
`plugin/list` and `plugin/installed`.
- Combine local marketplaces in request order, keeping the first source for
duplicates while merging installed and enabled state across repositories.
- Report invalid project configurations through `marketplaceLoadErrors` without
dropping valid local catalogs or globally enabled remote catalogs.
- Use the combined marketplace context for forced and background cache refreshes,
while keeping remote plugin feature gating request-wide.
## Testing
- Cover distinct and duplicate marketplaces, cross-repository enabled state,
invalid project configuration, local cache refresh, and global versus
project-local feature flags.
GitOrigin-RevId: 53c8e0e9c760dc2b969ab10d0e63fb439673c230
## Why
Remote plugin sync results need to identify which runtime categories may require
invalidation when a cached bundle changes.
## What changed
- Add `RemotePluginCapabilities` hints for MCP servers, Apps, hooks, and skills.
- Attach capability hints to materialized and removed plugins. Updates union the
declarations from the old and new bundles, while removals inspect the active
bundle before deleting its cache.
- Discover declarations without applying runtime policy or creating runtime
data directories.
## Testing
- Cover Agent Plugin capability discovery with an unavailable runtime data
directory.
- Cover capability accumulation across bundle versions and removal reporting.
GitOrigin-RevId: 338075d22d86f30f52be5785a2d87c77b33609c6
## Why
Executor plugin manifests are unsigned, so cleanup hooks must remain limited to
explicitly trusted plugin identities and MCP targets.
## What changed
- Allow the bundled Browser, Chrome, Chrome Dev, and Chrome Internal plugins to
run the existing `Stop` hook for `node_repl.turn_ended`.
- Continue allowing the bundled Computer Use plugin and rejecting unlisted or
lookalike marketplace identities.
## Testing
- Extend manifest-filtering coverage for unlisted bundled plugins and marketplace
name variants.
GitOrigin-RevId: 1ad5d679a1530994df5a9628c2117ce509fec9ad
## What changed
- Resolve plugin activation, MCP server policy, and marketplace definitions from the effective configuration stack, including system settings and trusted project overrides.
- Load plugin skills independently for each working directory passed to `skills/list`.
- Exclude project configuration from catalog requests whose `cwds` are omitted or empty.
- Cache up to eight loaded plugin configurations with least-recently-used eviction so requests for different working directories can reuse their results.
## Testing
- Cover layered plugin and MCP policy across trusted and untrusted projects.
- Cover per-directory skill and plugin catalog results, cache reuse and eviction, and system-defined marketplaces.
GitOrigin-RevId: cb68b2b1bdab1da48e05ca7562bc05014431fc71
## Why
MCP servers can share an OAuth callback URL. Without a validated issuer or a
server-specific callback path, an authorization response could be associated
with the wrong server.
## What changed
- Use stable callbacks when authorization metadata advertises issuer-bound
responses, and validate the returned issuer before exchanging the code.
- Retain server-specific callback IDs for providers without issuer support,
including fallback to the global or default callback for legacy registered
clients.
- Persist registered callback URLs for MCP servers and plugins, and insert the
active listener port into portless loopback redirects.
## Testing
Add coverage for issuer validation, callback-mode discovery, registered and
legacy clients, plugin OAuth, CLI persistence, and loopback listener ports.
GitOrigin-RevId: 2878c92e237fc17fd3def0bd2e1cce3e104a3db8
## Why
Removing a base-user marketplace must not delete a snapshot that is still
referenced by another enabled configuration layer.
## What changed
- Load the current configuration stack for marketplace commands in the CLI and
app server.
- Reject removal when a matching marketplace is defined by another enabled
layer, and identify the configuration source that must be updated instead.
- Allow cleanup of an installed marketplace snapshot even when no base-user
entry exists.
## Testing
Cover project, enterprise-managed, system, and session-flag configurations, as
well as snapshot-only removal through the CLI and app server.
GitOrigin-RevId: 4f0853a40c2b5fae0410696b79eee4284239c7a9
## What changed
- Add the experimental `amazonBedrockAccessKeys` app-server login flow, persist its credentials in the configured auth store, and use them for SigV4-signed Bedrock requests.
- Report `bedrockAccessKeys` as a distinct auth mode and document access-key login alongside AWS profile and environment credential setup.
- Clear the selected Bedrock provider, AWS settings, and Bedrock-specific model on logout while leaving external AWS credentials and `.env` untouched.
- Reject managed access-key login when higher-precedence configuration would prevent its region or profile settings from taking effect.
## Testing
- Cover access-key login, storage, request signing, configuration conflicts, status reporting, and logout cleanup.
GitOrigin-RevId: bbf297887c6503d3651ceb2aad85c4d626e32723
## What changed
- Cover forwarding a legacy `env_vars` entry when the portable MCP server has no `env` map.
- Use the test workspace variable instead of `PATH` in the stdio round-trip test, keeping overlay forwarding distinct from portable environment expansion.
GitOrigin-RevId: c5cfb333e553581fc856d43a04e5be0abd9f65ef
## What changed
- Apply local `env_vars` declarations from `.codex-plugin/plugin.json` to matching stdio servers loaded from an Agent Plugin manifest.
- Replace matching `${NAME}` entries in the portable server environment with host environment forwarding while preserving the portable command, arguments, and unrelated servers.
- Ignore remote-sourced environment variables and support both inline and file-based Codex MCP declarations.
## Testing
- Cover matching-server filtering, local and remote sources, inline declarations, and an end-to-end `PATH` forwarding round trip.
GitOrigin-RevId: 843e1232a084fa5f571fe56e07266995b87fd53d
## What changed
- Scope remote installed-plugin and loaded-plugin snapshots to the active account, and discard in-flight loads when the account changes.
- Serialize bundle reconciliation with direct installs and uninstalls, and use cache generations to prevent stale refreshes from overwriting newer state.
- Validate the complete installed-plugin snapshot before downloading bundles or removing stale cache entries, while retaining valid installed metadata when materialization fails.
## Testing
- Cover account changes during plugin loading, incomplete snapshots, refresh/reconciliation races, and reconciliation cancellation recovery.
GitOrigin-RevId: 694c25577b420b93dacc6c65e3c0ecb7b8cc64c3
## What changed
- Discover inline hooks from executor-provided plugin manifests and accept only
the bundled Computer Use `Stop` hook for `node_repl.turn_ended`.
- Add the accepted hook to the current step's hook engine with
executor-scoped provenance.
- Run executor-scoped hooks in the background after regular stop-hook
decisions, without delaying turn completion, applying control effects, or
exposing them in hook summaries. Skip them when regular hooks only block
continuation.
## Testing
- Added coverage for manifest filtering and option preservation.
- Added coverage for background execution, interaction with regular stop
hooks, and non-blocking turn completion.
GitOrigin-RevId: c0f75f83a23ba8a83bb3a5d5997c4882aacc32d6
## What changed
- Make `ExecutorFileSystem::walk` a required backend operation instead of
providing a fallback built from directory reads and metadata requests.
- Implement bounded local walks on a blocking task with cancellation, symlink
cycle detection, deterministic ordering, error collection, and response-size
limits.
- Have remote filesystems use the server's walk operation directly.
## Testing
- Cover local and remote handling of invalid roots and limits, directory
symlinks, non-UTF-8 names, cancellation, sandbox contexts, and response
budgets.
GitOrigin-RevId: 7499bf05080c3f9965a5eb7ffd593de604d62c2a
## What changed
- Create remote plugin metrics directories through the standard executor filesystem API.
- Remove the `private` directory-creation protocol option and its platform-specific handling.
- Update the executor temporary-directory documentation to describe child-visible sidecars without an owner-private guarantee.
GitOrigin-RevId: 9a8532403a3ad2bf998281735be0b668893918c9
## Why
An `apply_patch` path can be replaced with a symlink after verification, allowing an unsandboxed patch operation to reach a different file than the one that was approved.
## What changed
- Add `follow_symlinks` options to executor filesystem reads, writes, metadata lookups, directory creation, and removal, including the corresponding `followSymlinks` protocol fields.
- Implement no-follow filesystem operations on Unix and Windows that reject links in any path component and restrict file access to regular files.
- Run `apply_patch` with symlink traversal disabled when an otherwise-required sandbox is bypassed, while retaining the existing follow-symlink default for standalone callers.
## Testing
- Cover leaf and ancestor symlinks across patch add, update, delete, and move operations, including a path swap after verification.
- Exercise local and remote no-follow filesystem behavior, concurrent directory creation, special-file rejection, and Windows reparse points.
GitOrigin-RevId: 43fd479084891493ce13564fbd894b98f329c6dd
## What changed
- Stop writing `last_updated` and `last_revision` to marketplace entries in
`config.toml`; keep the activated revision in
`.codex-marketplace-install.json` instead.
- Use installed marketplace metadata to detect up-to-date checkouts.
- Snapshot the installed marketplace before activation and roll back a stale
upgrade if another installation changed the destination concurrently.
## Testing
- Verify marketplace add and upgrade operations leave `config.toml` unchanged.
- Cover restoring a newer concurrently installed marketplace when a stale
activation is rejected.
GitOrigin-RevId: 10942c3fc7c6c3f68b7d5953e8c1b5e86bf71866
## Why
Plugin installation skips symlinks while copying a plugin into the cache. A
symlinked manifest could therefore be used during source validation but omitted
from the staged copy, allowing a lower-precedence manifest to take its place.
## What changed
- Require discoverable manifests and their parent directories to be regular
files and directories, rejecting symlinks and other non-regular entries at a
higher-precedence manifest path.
- Verify that staging preserves the selected manifest path and contents before
activating the cached plugin.
- Preserve generated fallback manifests by injecting and validating them in the
staged plugin.
## Testing
Add coverage for symlinked manifest files and directories, precedence changes,
and fallback-manifest staging.
GitOrigin-RevId: 1b69c1e75cdfecb8cab4070a32aa9739833a70de
## Why
The pre-trust remote lookup must not inherit Git configuration from the
repository that launched Codex, where URL rewrites can invoke custom transport
helpers during an automatic plugin sync.
## What changed
- Add a Unix regression test that runs the startup lookup from a repository
with a local `insteadOf` rewrite to an `ext` transport and verifies that the
helper is not executed.
- Reuse `OPENAI_PLUGINS_GIT_URL` for the lookup so the production command and
regression fixture target the same remote.
GitOrigin-RevId: e53af4a82a4206c31bf0f4733f908dcc064a4795
## Why
Background marketplace and plugin refreshes can otherwise inherit repository-local or command-scoped Git configuration from the project that launched Codex. That configuration can redirect remotes or invoke Git helpers during an automatic operation.
## What changed
- Run automatic marketplace upgrades, plugin cache refreshes, and curated marketplace lookups with repository-scoped Git environment variables removed and a temporary trusted repository under the Codex home.
- Carry the automatic/manual trust mode through marketplace upgrades and plugin materialization.
- Preserve the caller's Git configuration for explicit marketplace upgrades, plugin installs, and refreshes.
## Testing
- Add regression coverage for repository URL rewrites, protocol helpers, command-scoped configuration, and manual Git filters.
GitOrigin-RevId: 957f45fa3bd7ce7e1b83355f276cf65dc5e99c8e
## What changed
- Give plugin managers for the same cache root a shared semaphore that permits
only one background installed-plugin bundle sync at a time.
- Hold the permit for the lifetime of the spawned sync task and refresh the
installed-plugin cache after a successful local cache change.
## Testing
- Add a test that starts bundle syncs from two plugin managers sharing a Codex
home and verifies that only one request is made.
GitOrigin-RevId: 86c39476c3a9015b9862ab75e8f11f110b0284fc
## Why
Repository manifests and user-configured sources must not be able to claim names reserved for managed or remote marketplaces.
## What changed
- Reject reserved marketplace names from unmanaged sources during discovery, installation, configuration projection, and configured marketplace upgrades, even when source restrictions are disabled.
- Recognize managed marketplaces only at their expected paths. Preserve the required macOS and Windows path equivalences without allowing symlink aliases to inherit managed provenance.
## Testing
- Cover reserved-name rejection for plugin list and install RPCs, configured upgrades, unrestricted policy, and remote marketplace names.
- Cover symlink spoofing and Windows managed-path normalization.
GitOrigin-RevId: a610bdc382857f306dd3e244f0992de2ec279673
## Why
Tree-sitter can represent brace expansions, globs, and escaped text as plain
words even though the shell changes them at runtime. Treating their source text
as literal argv could let a command match a safe-command check or allow rule
that does not match what will actually execute.
## What changed
- Reject unquoted Bash and Zsh words containing expansion, glob, or escape
syntax from literal command parsing, including heredoc command prefixes.
- Reject double-quoted escape sequences that the shell removes or interprets,
while continuing to accept quoted metacharacters that remain literal.
- Require approval for affected commands under `UnlessTrusted`, even when a
policy contains an allow rule for the unexpanded source text.
## Testing
Add parser and approval scenarios covering brace expansion, globs, escapes,
Zsh-specific syntax, heredocs, and quoted literals.
GitOrigin-RevId: 31f2c6062680c42ac65362e3f3eebfaaf4eb71da
## What changed
- Fetch recommendations from the Codex-specific `/ps/plugins/suggested/codex` endpoint and parse its compact response shape.
- Fetch the selected plugin's details before presenting an install request, using them to verify availability and populate connector metadata.
- Skip install elicitation when the selected recommendation is no longer available, and return a retryable response when its metadata cannot be verified.
## Testing
- Cover the new recommendation route and response shape.
- Cover metadata hydration for available plugins and rejection of unavailable plugins.
GitOrigin-RevId: 2b0e2d70572aae2b7cd8e458b42e9dd14be3dbaf
## What changed
- Give `PluginsManager` a shared `AuthManager` instead of a separately mutable authentication-mode snapshot.
- Read the current authentication mode and credentials from that shared manager for plugin discovery, startup tasks, CLI commands, MCP setup, and external-agent migration.
- Update test helpers and coverage to exercise plugin projections and curated marketplace selection as authentication changes.
GitOrigin-RevId: 600c94de5130eda2da5727e1a0b4d39083fefc56
## What changed
- Resolve MCP server policy directly from the effective user configuration for selected executor-plugin roots.
- Apply server enablement, tool allow/deny lists, and default and per-tool approval modes while preserving stricter plugin-declared restrictions.
- Cover policy merging and opaque selected-root IDs in the executor-plugin MCP integration tests.
GitOrigin-RevId: dce3021969ba71e642de52312449cab6277515c3
## What changed
- Stop parsing and exposing the `model` field from skill frontmatter.
- Remove the skill model delegation types and instruction generation.
GitOrigin-RevId: 01198c68c095da5062e8abec417cc3539099d9d5
## What changed
- Rebuild hook runtimes for loaded sessions when effective plugins change or a marketplace upgrade installs new plugin content.
- Refresh plugin-related caches and MCP runtimes alongside hooks after plugin mutations.
- Preserve each loaded session's current configuration while rebuilding its hooks.
## Testing
- Cover direct plugin upgrades, including subsequent turn and session-end hooks.
- Cover automatic marketplace upgrades for an already loaded session.
GitOrigin-RevId: fef64c68d652f300c7f3d88e81c5017459aa9a18
## What changed
- Add an optional `model` field to parsed and loaded skill metadata.
- Recognize `model: luna` while ignoring unsupported model values without
preventing the rest of the skill metadata from loading.
## Testing
- Cover supported, absent, unsupported, and repaired frontmatter model values.
GitOrigin-RevId: 376b65555e81d29a5eae93cc4c2633aacf7cd7c8
## What changed
- Add `oauth.callback_port` to MCP server configuration and preserve it when
serializing configuration edits.
- Accept `oauth.callbackPort` from plugin MCP declarations and skill dependency
metadata.
- Prefer the server-specific callback port over `mcp_oauth_callback_port` for
CLI login, app-server, plugin installation, executor, and skill dependency
OAuth flows.
## Testing
- Cover configuration parsing, serialization, and fallback behavior.
- Verify plugin, executor, and skill OAuth registrations use their configured
callback ports instead of the global port.
GitOrigin-RevId: 7f65e5e7869358307e49779f1b75e8672b607736
## Why
The model provider does not reliably identify which curated plugin catalog is
available. ChatGPT authentication can be used with a custom provider, while an
unauthenticated session should use the API-compatible catalog regardless of its
provider.
## What changed
- Select the ChatGPT curated catalog only for authentication modes that use the
Codex backend; use the API curated catalog for API-key and unauthenticated
sessions.
- Initialize standalone plugin managers with the current authentication mode
across CLI, app-server, MCP, and external-agent migration paths.
- Preserve authentication mode while detecting and importing migrated plugins.
## Testing
- Cover catalog and skill routing across ChatGPT, API-key, unauthenticated,
Bedrock, and custom-provider configurations.
- Verify authenticated plugin migration uses the ChatGPT curated marketplace.
GitOrigin-RevId: 660a339ee8891c33aad961078d3a979242a6a166
## 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
- 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
- Add `http_headers_helper` configuration for local streamable HTTP MCP servers. The configured shell command runs once per connection and returns a JSON object of headers that is cached across requests.
- Apply helper headers to MCP startup and OAuth flows while restricting them to the server origin, stopping redirects, rejecting reserved or duplicate headers, and enforcing output and execution limits.
- Reject helpers for remote or managed-disabled servers, use the local environment working directory, and redact helper commands from `codex mcp list` and `codex mcp get` output.
## Testing
- Cover configuration validation, helper lifecycle and output parsing, origin isolation, OAuth discovery and token refresh, managed requirements, environment selection, and CLI redaction.
GitOrigin-RevId: 84e0e26ce75520b0869d37c72b1678e033bd6818
## 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
- 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
- Remove the path-only `effective_skill_roots` API and its type-erasing trait in favor of `effective_plugin_skill_roots`, which preserves plugin metadata.
- Remove skill-path ancestor lookup helpers and keep namespace resolution scoped to an explicit plugin root.
- Update plugin manager and namespace tests to exercise the retained APIs directly.
GitOrigin-RevId: 507bf43bc6147bb5ab2deba4fa176bea2535159c
## 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
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
## 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
## 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
- 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.

## 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.

## Why
Plugin suggestions should report skills only when the plugin has an enabled skill.
## What changed
- Load suggestion metadata through the shared plugin skill-root loader.
- Apply skill configuration when setting `has_skills` on suggestion candidates.
## Testing
Added coverage for local plugin suggestions with the plugin skill both enabled and disabled.
