MiroFish is an open-source AI simulation engine that rehearses the future by spawning personas with distinct incentives, biases, and memory, then letting them interact across social surfaces over multiple rounds. Unlike single-model Q&A, it produces emergent dynamics you can't script.
Mirofish Simulation is a community-contributed Claude Code skill in the product-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/mirofish-simulation/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when analyzing campaign outcomes, policy impacts, market reactions, PR crisis scenarios, or any multiplayer situation where human behavior is key. Triggers: scenario simulation, outcome prediction, decision rehearsal, campaign pressure testing, multi-agent analysis, stakeholder simulation, what-if analysis, scenario planning.
The Mirofish Simulation Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 70,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
