Self-hosted Matrix agent assistant
Custom agent: The author had Kimi set up a local Matrix server and write a small custom agent loop with sandboxed tools.
A working personal agent the author reaches by Matrix from phone, home web app, or CLI agents.
Overview
How it was set up
Kimi and GLM5 run the agents. Tools run under bubblewrap sandboxing. A self-hosted Matrix server with federation off, behind WireGuard, plus identity, soul, and memory files, a heartbeat, and reminders.
Worth knowing
Bubblewrap is not enough for untrusted data, so a VM is planned. Agents have web access, so leaks are possible.
