Show HN: Phantom — Open-Source Self-Evolving AI Agent on Its Own VM, Built on Claude Agent SDK

Hacker News·low signal

Phantom (ghostwright/phantom, 18pts/16 comments) is an Apache 2.0 AI co-worker that deploys to a dedicated VM, communicates via Slack, has its own email, and rewrites its own configuration after every conversation. The self-modification pipeline: observe → reflect → propose config changes → validate through a different LLM model (to avoid self-enhancement bias) → evolve. Exposes 17+ tools as an MCP server so other AI agents and IDEs can plug into it. Built on Anthropic's Claude Agent SDK, representing the emerging pattern of persistent, self-improving agents with full computer access.
