## 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.

## What changed
- Restrict host loading, snapshot, and outcome implementation details to the
skills extension crate.
- Require `HostSkillsLoadInput` construction through its public constructor
instead of exposing its fields.
- Remove redundant implicit-invocation helpers from `SkillLoadOutcome`; use the
`ImplicitSkillLookup` interface for enabled-skill lookup instead.

## Why
The app server should not need access to host skill root internals to decide
which paths require filesystem watching.
## What changed
- Add `HostSkillsService::watchable_skill_root_paths` to return non-plugin,
non-system skill roots for the watcher.
- Make `HostSkillRoot` and root resolution private to the skills extension.
- Update the app-server watcher to consume the filtered paths directly.
## Testing
Add a host service test confirming that user skill roots remain watchable while
plugin and generated system roots are excluded.

## Why
A single `skills/list` request should use one view of shared skill roots across
all requested workspaces while still applying each workspace's skill rules.
## What changed
- Add a request-scoped host skills view that reuses non-plugin root snapshots
across `cwd` entries without persisting them across requests.
- Resolve user-scoped plugin skill roots once per request, then apply workspace
skill configuration separately for each `cwd`.
- Make `forceReload` refresh plugin roots before building the request-scoped
view so subsequent entries see the refreshed skills.
## Testing
Expanded `skills/list` and host skills service tests to cover multiple ordered
workspaces, per-workspace skill rules, request-local snapshots, cached results,
and forced plugin-root refreshes.
GitOrigin-RevId: eedd3a4c3e213b7f30df6cacd3adf23ba2967437
## What changed
- 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
- 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.
GitOrigin-RevId: 214d06d59bf3033ee0f220ea5959ee4feff66782
## What changed
- Inject the host skill loader into `PluginsManager` so plugin discovery and agent turns use the same loading and product-policy behavior.
- 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.
GitOrigin-RevId: f5ef0d0766ebeeb30d73ffaf044d003c2906ea4d
## What changed
- Carry plugin identity, namespace, root, and discovery mode through host skill loading.
- Apply the owning plugin namespace and IDs to loaded skill metadata.
- Respect direct-child discovery for Agent Plugins and reject skills that resolve outside the plugin root or are not regular files.
- Preserve recursive discovery and symlink behavior for legacy plugin roots, and allow the full 64-character namespace plus 64-character skill name.
## Testing
Add host-loader coverage for plugin metadata, namespace ownership, direct-child filtering, path containment, recursive symlinks, shared assets, and maximum-length qualified names.
GitOrigin-RevId: cdde821643ce39bd030d0c3753b3304b75161690
## 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.
GitOrigin-RevId: c18080afb917c33c57bc17e36b40dd0f3c72d1d7
## What changed
- Key cached skill snapshots by filesystem and plugin snapshot identity so compatible config and working-directory loads can share results without reusing stale plugin data.
- Coalesce concurrent loads for the same cache key and replace the cached entry on forced reload.
- Clear both plugin and skill caches when `skills/list` forces a reload, and bypass working-directory caching when effective plugin roots are present.
## Testing
- Cover concurrent cache sharing, filesystem isolation, forced reloads, and refreshed plugin skill metadata in host service and app server tests.
GitOrigin-RevId: 03fed3b40d45bb29206d5a3c3e78f06df04dbb1e
## Why
The bundled system-skill cache is shared by every process using the same
`CODEX_HOME`. A service with bundled skills disabled must not remove cache
files that another service still uses.
## What changed
- Filter system skill roots from disabled services without deleting the shared
cache.
- Ensure bundled system skills are installed during loads when they are
enabled, including after a runtime configuration change.
## Testing
Add app-server coverage for preserving the cache across enabled and disabled
services and refreshing stale cached skills after runtime enablement.
GitOrigin-RevId: 1eca999b33b7be69873a40a91767fd26f0c2b457
## What changed
- Move config-layer, user, system, plugin, extra, and repository skill-root
resolution from `core-skills` into the host skills extension.
- Keep the core loader focused on loading explicit `SkillRoot` values.
- Relocate and expand tests for root precedence, deduplication, repository
ancestry, plugin metadata, and concurrent probing.
GitOrigin-RevId: 3b95cf28101b8b4d64d54079d202154dad560aab
## What changed
- Move host skill discovery, snapshot caching, and configuration handling from
`codex-core-skills` to `codex-skills-extension`.
- Rename `SkillsService` and `SkillsLoadInput` to `HostSkillsService` and
`HostSkillsLoadInput` to distinguish the host implementation from other skill
providers.
- Keep shared loading primitives and skill outcome modeling in
`codex-core-skills`.
