v1.2.1

Hearth v1.2.1 — the agent-native 2D game engine.

v1.2 highlights

  • Asset-pack intelligence across CLI and MCP: provenance, Tiled metadata, compatibility diagnostics, vision contact sheets, fixed atlas-frame Tilemaps, and stronger validation.
  • Embedded agent terminals now survive sleep/wake and brief socket loss by detaching, buffering output, and reattaching automatically.
  • Revised built-in art/build guidance teaches agents to inspect, visually verify, and prove unfamiliar packs before production placement.

Desktop app: download the build for your OS below.
macOS builds are Developer-ID signed and notarized. Windows builds are not code-signed yet, so SmartScreen may require "More info" → "Run anyway" on first launch.

Agent tools (no install needed, any Node ≥ 20):

  • node hearth-cli.mjs --help — the full hearth CLI
  • node hearth-mcp.mjs --project <your game> — MCP server for Claude Code / any MCP client
  • hearth-player.js — the web-export player; keep it next to the CLI (or set HEARTH_TOOLS_DIR) so export web works
