Codex CLI 0.128.0 adds /goal

Original coverage: Simon Willison ↗·How Modelwire adds context
The development
OpenAI's Codex CLI now supports autonomous goal-setting via a /goal command that implements a Ralph loop pattern, allowing the agent to iteratively work toward objectives within token budgets. This represents a shift toward more self-directed code generation workflows, where models can reason about task completion rather than executing single-shot requests. The feature signals OpenAI's investment in agentic coding tools that balance autonomy with resource constraints, a key tension as LLM-powered development assistants mature.

Modelwire analysis
ExplainerOur AI-generated reading of the wider context and the next developments to watch.
The Ralph loop name is a reference to a specific agentic architecture pattern (observe, plan, act, reflect) rather than a proprietary OpenAI invention, which means the real story here is that Codex CLI is now exposing a well-understood agent design to everyday developers through a simple slash command rather than requiring them to wire up the loop themselves.
Modelwire has no prior coverage to anchor this to directly. This story belongs to a broader thread around agentic coding tools, where the central question is how much autonomous decision-making should be delegated to a model mid-task versus kept under explicit human control. The token budget constraint mentioned in the summary is doing real work here: it is the mechanism that keeps the loop from running indefinitely, and it is the kind of practical guardrail that distinguishes a shipping feature from a research demo.
Watch whether third-party benchmarks on multi-step coding tasks (SWE-bench variants in particular) show measurable completion rate improvements with /goal enabled versus standard single-shot Codex CLI usage. If the gains are real, expect competing CLI tools like Aider or Continue to ship equivalent loop abstractions within two to three months.
