From 54b7637ec825c77b01d2ae0192575bde539a76bc Mon Sep 17 00:00:00 2001 From: leetcrypt Date: Mon, 1 Jun 2026 02:05:48 -0700 Subject: [PATCH] feat(agent): model-agnostic AI agent bridge (PoC) + pin lets-hack demo to main Add cmd_chat/agent: a headless client that joins a room via SRP, decrypts broadcasts, and answers /ai through a pluggable model provider (ollama default + anthropic + openai-compatible + module:Class). Server and zero-knowledge guarantees unchanged; the agent is just another encrypted client. Also pin the lets-hack demo to a detached worktree of main (default) so running it from dev still demos stable main without touching the working checkout.
