Codex CLI enables instant session recovery
The OpenAI Codex CLI features a resume --last command designed to restore terminal-based coding sessions after crashes or restarts. By leveraging local JSONL history files, the tool allows developers to pick up agentic workflows exactly where they left off, preserving full project context without manual re-entry.
Persistence is becoming the defining feature for professional AI developer tools as they move from simple chat interfaces to long-running autonomous agents.
- –Local storage of session transcripts ensures that context is never lost to network interruptions or system failures.
- –The directory-scoped recovery model aligns perfectly with developer workflows, where context switching between projects is common.
- –Skipping the interactive session picker via the `--last` flag reduces friction for high-velocity iterative development.
- –This pattern of local-first persistence is likely to become standard across all agentic CLIs to mitigate the cost of re-prompting large contexts.
