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 or stop) go to JEV in milliseconds, and the big models only see the ones that split the full tree > Opus 5.5 runs the main session and writes workflow.js > pipeline() fans out the new Haiku 5.5 to audit every file > parallel() schema validators drop false positives in V8 > Sonnet 5.5 patches each fix in an isolated worktree > verify cross-checks all diffs before reporting > Opus 5.5 reads only what survived verification > JEV routes micro-forks in milliseconds paste the tree and this prompt into Claude Code ↓ "Rebuild my Claude Code setup around this tree: 1. Run the main session on Opus 5.5 with ultracode on 2. In every workflow, run read-only scan stages on the new Haiku 5.5 and edit stages on Sonnet 5.5, each edit in its own isolated copy 3. Add one rule to CLAUDE.md: every finding gets an independent verifier agent before it's reported, and fix loops stop after two rounds with no progress 4. Route fast deterministic forks (tool choice, path selection, retries) through JEV Show me every change as a diff first, no edits until I say go" ↳ http://code.claude.com/docs/en/workfl… save it, it'll come in handy
