Amplifier
About
Microsoft positions Amplifier as an open research demonstrator for modular agent design: the CLI is explicitly just one interface over a platform intended to grow web, mobile, and IDE surfaces. Bundles compose configuration — the foundation bundle ships filesystem/bash/web/search/task tools, fourteen agents (zen-architect, bug-hunter, modular-builder...), and behaviors like redaction and todo tracking — while external bundles install via amplifier bundle add from any git URL. Sessions persist per project and resume with amplifier continue, and a companion log viewer replays sessions for debugging. Providers are swappable at runtime (Anthropic, OpenAI, Azure OpenAI, Ollama); the MIT-licensed project is an early preview that explicitly warns safety systems are incomplete, is not accepting external contributions, and has 3.1k stars.
