## Summary - Tightens Plan Mode to encourage exploration-first behavior and more back-and-forth alignment. - Adds a required TL;DR checkpoint before drafting the full plan. - Clarifies client behavior that can cause premature “Implement this plan?” prompts. ## What changed - Require at least one targeted non-mutating exploration pass before the first user question. - Insert a TL;DR checkpoint between Phase 2 (intent) and Phase 3 (implementation). - TL;DR checkpoint guidance: - Label: “Proposed Plan (TL;DR)” - Format: 3–5 bullets using `- ` - Options: exactly one option, “Approve” - `isOther: true`, with explicit guidance that “None of the above” is the edit path in the current UI. - Require the final plan to include a TL;DR consistent with the approved checkpoint. ## Why - In Plan Mode, any normal assistant message at turn completion is treated as plan content by the client. This can trigger premature “Implement this plan?” prompts. - The TL;DR checkpoint aligns on direction before Codex drafts a long, decision-complete plan. ## Testing - Manual: built the local CLI and verified the flow now explores first, presents a TL;DR checkpoint, and only drafts the full plan after approval. --------- Co-authored-by: Nick Baumann <@openai.com>
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.
