## 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.

## What changed
- Move skill interface validation and asset-path resolution into `codex-skills` so both skill loaders share the same behavior.
- Populate host-loaded skills with validated display metadata, prompts, brand colors, and local icons from `agents/openai.yaml`.
- Allow plugin skills to reference icons under the plugin's shared `assets` directory while rejecting absolute paths and paths that escape permitted asset roots.
## Testing
- Add resolver tests for valid, invalid, local, and plugin-shared interface assets.
- Add host loader coverage for interface fields and asset-path restrictions.

## What changed
- Move parsing of pre-discovered executor skill bundles from `core-skills` to
the skills extension.
- Expose shared `SKILL.md` frontmatter parsing from `codex-skills` so direct
and pre-discovered loading use the same validation and repair behavior.
## Testing
- Add parity coverage for direct and pre-discovered executor skill catalogs,
including plugin namespaces, metadata, product policy, and warnings.
- Add a snapshot for the resulting pre-discovered executor catalog.

## What changed
- Define and export skill metadata, policy, dependency, interface, and configuration rule types from `codex-skills`.
- Update core, plugin, and extension consumers to use the shared models while retaining compatibility re-exports from `codex-core-skills`.
- Share product-restriction handling between host and environment skill metadata.
## Testing
- Add unit coverage for default and explicit implicit-invocation and product policies.

## Why
`codex-core` was carrying the embedded system-skill sample assets (and a
`build.rs` that walks those files to register rerun triggers). Those
assets change infrequently, but any change under `codex-core` still ties
them to `codex-core`'s build/cache lifecycle.
This change moves the embedded system-skills packaging into a dedicated
`codex-skills` crate so it can be cached independently. That reduces
unnecessary invalidation/rebuild pressure on `codex-core` when the
skills bundle is the only thing that changes.
## What Changed
- Added a new `codex-rs/skills` crate (`codex-skills`) with:
- `Cargo.toml`
- `BUILD.bazel`
- `build.rs` to track skill asset file changes for Cargo rebuilds
- `src/lib.rs` containing the embedded system-skills install/cache logic
previously in `codex-core`
- Moved the embedded sample skill assets from
`codex-rs/core/src/skills/assets/samples` to
`codex-rs/skills/src/assets/samples`.
- Updated `codex-rs/core/Cargo.toml` to depend on `codex-skills` and
removed `codex-core`'s direct `include_dir` dependency.
- Removed `codex-core`'s `build.rs`.
- Replaced `codex-rs/core/src/skills/system.rs` implementation with a
thin re-export wrapper to keep existing `codex-core` call sites
unchanged.
- Updated workspace manifests/lockfile (`codex-rs/Cargo.toml`,
`codex-rs/Cargo.lock`) for the new crate.
