MiroFish CLI
Social simulation engine. Feed it documents and a plain-English requirement; it builds a knowledge graph, spins up AI agents that post and argue on simulated Twitter and Reddit, then writes a report, a machine-readable verdict.json, and SVG snapshots.
Fork of 666ghj/MiroFish, translated to English and reduced to a CLI that runs on the claude or codex CLI.
