#### What Add structured `@plugin` parsing and TUI support for plugin mentions. - Core: switch from plain-text `@display_name` parsing to structured `plugin://...` mentions via `UserInput::Mention` and `[$...](plugin://...)` links in text, same pattern as apps/skills. - TUI: add plugin mention popup, autocomplete, and chips when typing `$`. Load plugin capability summaries and feed them into the composer; plugin mentions appear alongside skills and apps. - Generalize mention parsing to a sigil parameter, still defaults to `$` <img width="797" height="119" alt="image" src="https://github.com/user-attachments/assets/f0fe2658-d908-4927-9139-73f850805ceb" /> Builds on #13510. Currently clients have to build their own `id` via `plugin@marketplace` and filter plugins to show by `enabled`, but we will add `id` and `available` as fields returned from `plugin/list` soon. ####Tests Added tests, verified locally.
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.
Network access and filesystem read/write roots are controlled by
SandboxPolicy. Seatbelt consumes the resolved policy and enforces it.
Seatbelt also supports macOS permission-profile extensions layered on top of
SandboxPolicy:
- no extension profile provided:
keeps legacy default preferences read access (
user-preference-read). - extension profile provided with no
macos_preferencesgrant: does not add preferences access clauses. macos_preferences = "readonly": enables cfprefs read clauses anduser-preference-read.macos_preferences = "readwrite": includes readonly clauses plususer-preference-writeand cfprefs shm write clauses.macos_automation = true: enables broad Apple Events send permissions.macos_automation = ["com.apple.Notes", ...]: enables Apple Events send only to listed bundle IDs.macos_accessibility = true: enablescom.apple.axservermach lookup.macos_calendar = true: enablescom.apple.CalendarAgentmach lookup.
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.
