# syntax=docker/dockerfile:1
# Hermes Agent — lightweight overlay
# Adds Piper TTS, Himalaya email CLI, and extra system deps on top of the
# official image. No source overlay — uses upstream as-is, so kanban and
# all native v0.12.0 features are available without forking.
#
# Build:
#   docker compose build hermes

# ---------- Base: official Hermes image (v0.12.0+ kanban, gateway, dashboard) ----------
FROM nousresearch/hermes-agent:latest

# ---------- Extra system packages ----------
