Opus 5 reportedly re-reviews subagent output far more than 4.x did
RickySpanishLives · reddit · 2026-07-26
A user reports that Opus 5 behaves differently from the 4.x generation in autonomous subagent workflows.
Their previous process was to have the model brainstorm, dump the plan to Markdown, clear the session, then execute the plan autonomously with subagents. With Opus 5, however, the main agent spends a lot of time re-reviewing subagent output, which makes the user trust it less as a fully autonomous worker.
Key complaints include:
- More vague thinking traces
- A sense of inconsistency between main agent and subagents
- Better results when subagents are not used
- Lower trust than 4.x for autonomous subagent operations
The user notes that all subagents are also Opus, forced by the workflow.
