How I built a multi-agent simulator as a native SwiftUI app

说明与用途

Sorcerer 是一款免费的 macOS 应用，使用现有 CLI 工具和纯函数模拟 AI 角色互动，无需 API 密钥。

问题

Develop a free, open‑source macOS app that simulates a community of AI characters reacting to user‑defined hypotheses without requiring API keys.

结果

Sorcerer enables rapid, key‑free simulation of AI communities, with testable logic and live streaming feedback.

工作流

• 1. Prompt user for hypothesis and cast
• 2. Detect user PATH by launching /bin/zsh -ilc "printf '%s' $PATH"
• 3. Select provider CLI (claude, codex, ollama) and construct command with appropriate flags
• 4. Run provider, stream JSON output
• 5. Parse partial JSON to show live typing
• 6. Validate and apply round results via pure functions
• 7. Update world state and display posts, reactions, memories
• 8. Allow forking of world branches

证据

I built Sorcerer, a free, open‑source macOS app (SwiftUI, macOS 15+, MIT) that simulates a community of AI characters reacting to a "what if…?" question.

来源

Sorcerer runs the official tools the user is already signed in to: the claude CLI (Claude Code), the codex CLI (ChatGPT), or a local Ollama.

The simulation lives in Engine.swift, whose header says "Prompts and parsing. Pure functions, so the simulation rules are testable without a model."
