Codex App Server Persisted

[Created by Codex: 019b74f5-a7d5-7121-ac48-8e66cd2bdc92]

Purpose

Provide a repeatable workflow to keep a single Codex process running in memory via codex app-server, and drive multi-turn interactions by sending thread/start once and turn/start repeatedly on the same threadId.

When To Use

• Need a warm, long-lived Codex PID to minimize turn-to-turn latency
• Need programmatic control over turns (JSON-RPC over stdio) instead of a TUI
• Need built-in observability via sse_lines.jsonl (works with app-server, not with mcp-server)

Workflow

1) Confirm requirements
