THIS IS A PURE F*CKING GOLDMINE Anthropic just shared the sharpest trick for Claude Code The idea: let Opus 5.5 write the plan as a script, and swarm the new Haiku 5.5 in parallel Huge sweeps with zero Opus burn: the script holds the loop and Opus only sees the final diff You just launch Claude Code like this: claude --model opus --effort ultracode here's the split: → Opus 5.5 turns your objective into an executable workflow script → Haiku 5.5 swarms every file in parallel at 340 tok/s to extract candidates → Sonnet 5.5 patches each fix and cross-checks findings in its own isolated copy → you stop burning Opus context on a hundred agent transcripts Opus only shows up at three moments: → authoring the workflow script before the run → reading verified findings after the swarm finishes → signing off before anything ships to git Opus plans · Haiku scans · Sonnet ships JEV engineering is the same move one layer down: the forks that need no thinker (which file, which tool, retry o
