Codex CLI Exec Mode Experiments

Date: 2026-03-13 CLI Version: 0.114.0 Total Experiments: 81

Raw experiment outputs from testing various codex exec flag combinations.

Note: Some experiment outputs include MCP (Model Context Protocol) server startup messages (e.g., mcp: flywheel starting, mcp: exa ready). These are from the author's local Codex configuration and do not affect experiment results. Your output may differ depending on your configured MCP servers.

Serverless Claude Code Instances with Persistent Compute

1. Problem

We need a way to give each Discord channel its own persistent "computer" running Claude Code CLI, where:

The computer survives across sessions (disk persists)
It wakes up fast when a user sends a message (< 10s, ideally < 5s)
It costs near-zero when idle

	#!/usr/bin/env bash
	# fix-setapp.sh — Kill Setapp apps, wait for stable agent, relaunch apps.
	#
	# Usage: ./fix-setapp.sh
	#
	# Based on diagnosis in setapp-intermittent-launch-failure.md
	# SetappAgent v3.49.10 crashes within ~60s of startup (SIGSEGV).
	# This script automates the recovery: kill apps → stabilize agent → relaunch.

	# After that, you can edit ~/.aerospace.toml to your liking

	# It's not necessary to copy all keys to your config.
	# If the key is missing in your config, "default-config.toml" will serve as a fallback

	# You can use it to add commands that run after AeroSpace startup.
