Codex Sub-Agents Quickly Drain Credits
ssh4net · x · 2026-07-10
A shared config.toml snippet for Codex's multiagentv2 includes:
- hidespawnagentmetadata = false
- toolnamespace = "agents"
The post points out a flaw in Codex's sub-agent orchestration: the spawnagent tool cannot specify the model or reasoning effort for sub-agents. Consequently, every time the main agent spawns a sub-agent, it launches another identical Sol Ultra instance, causing credits to drain rapidly.
