README.md

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_preferences grant: does not add preferences access clauses.
macos_preferences = "readonly": enables cfprefs read clauses and user-preference-read.
macos_preferences = "readwrite": includes readonly clauses plus user-preference-write and 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: enables com.apple.axserver mach lookup.
macos_calendar = true: enables com.apple.CalendarAgent mach 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.
