This PR adds support for loading [skills](https://developers.openai.com/codex/skills) from `.agents/skills/`. - Issue: https://github.com/agentskills/agentskills/issues/15 - Motivation: When skills live on the filesystem, sharing them across agents is awkward and often ends up requiring symlinks/duplication. A single location under `.agents/` makes it easier to share skills. - Loading from `.codex/skills/` will remain but will be deprecated soon. The change only applies to the [REPO scope](https://developers.openai.com/codex/skills#where-to-save-skills). - Documentation will be updated before this change is live. Testing with skills in two locations of this repo: <img width="960" height="152" alt="image" src="https://github.com/user-attachments/assets/28975ff9-7363-46dd-ad40-f4c7bfdb8234" /> When starting Codex with CWD in `$repo_root` (should only pick up at root): <img width="513" height="143" alt="image" src="https://github.com/user-attachments/assets/389e1ea7-020c-481e-bda0-ce58562db59f" /> When starting Codex with CWD in `$repo_root/codex-rs` (should pick up at cwd and crawl up to root): <img width="552" height="177" alt="image" src="https://github.com/user-attachments/assets/a5beb8de-11b4-45ed-8660-80707c77006a" />
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
When using the workspace-write sandbox policy, the Seatbelt profile allows
writes under the configured writable roots while keeping .git (directory or
pointer file), the resolved gitdir: target, and .codex read-only.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
