Codex CLI Explains Safety Blocks and Offers Safer Follow-Up Prompts in the TUI

CodexView original changelog

Codex CLI 0.166.0 added clearer safety-block explanations and selectable safer follow-up prompts to the terminal UI. When a request is stopped by a safety policy, the TUI now says why and lets the developer pick a safer way to continue.

Key Takeaways

  • Safety blocks in the Codex CLI TUI now explain themselves, with clearer messaging in 0.166.0 about why a request was stopped.
  • The TUI offers selectable safer follow-up prompts, so a blocked request can lead to a next step rather than a dead end.
  • The linked pull request titles point to turn-scoped recourse and safer rewrites, though the notes do not elaborate on either.
  • The change is a terminal UI improvement that regular Codex CLI users can notice, rather than an admin or configuration feature.
  • The release notes are brief and do not specify which policies trigger the feature, how prompts are generated, or whether it is configurable.
  • The change ships in Codex CLI 0.166.0, released on October 29, 2026, alongside keyboard-driven transcript selection.

Safety Blocks Now Come With an Explanation and a Next Step

Codex CLI 0.166.0 changed how the terminal UI handles requests stopped by a safety policy. The release notes describe two additions: clearer safety-block explanations and selectable safer follow-up prompts. Together, they mean a blocked request no longer ends at a refusal. The TUI explains the block and offers prompts the developer can choose to continue.

Clearer Explanations

The first change is about understanding why a request was blocked. The release notes say the TUI now gives clearer safety-block explanations. The linked pull request is titled "Explain safety policy blocks with turn-scoped recourse in the TUI," which indicates the explanation is tied to the turn in which the block occurred and points to a course of action.

Selectable Safer Follow-Up Prompts

The second change is about what to do next. After a safety block, the TUI now presents safer follow-up prompts that the developer can select. A second linked pull request is titled "Offer safer rewrites after safety blocks in the TUI," which suggests the prompts are alternative phrasings of the original request.

What the Release Notes Do Not Say

The release notes cover this change in a single line, plus the two pull request titles. They do not specify:

  • which safety policies or kinds of requests trigger the new explanations,
  • what the explanation text says or how it is laid out,
  • how the safer prompts are generated, how many are shown, or which key selects one,
  • whether the behavior can be configured or turned off.

This article therefore limits itself to what is stated: the TUI in Codex CLI 0.166.0 explains safety blocks more clearly and offers selectable safer follow-up prompts.
