Every command goes through a parser (Claude Sonnet 4.6) which returns a task plan as JSON. Tasks can be parallel or sequential — when one task depends on another (e.g. an HTML page that needs generated images), the parser sets a dependsOn field.
The executor then:
When Claude is the orchestrator (and other models depend on it), it switches into creative-director mode and writes labeled sections like [FLUX]...[/FLUX], [ELEVENLABS]...[/ELEVENLABS] — each section feeds the matching downstream model as its prompt.
