All signals →r/ClaudeAI thread on Anthropic's subagent guide: commenters defend cross-model review
The poster summarises Anthropic's 22 October guide on folding subagents into one agent loop and says they went from about six subagents to two. Several commenters say having a second model from another provider review the main agent's plan catches mistakes, at the cost of speed and tokens. Anecdotes, not measurements.
Why it matters It is the strongest pushback to the guide's advice: if verification is the job a subagent does, the guide itself keeps it, so test before you remove it.
