daimon-engine 2.0.3

DAIMON — open-source agentic-first autobattler with native pywebview UI

DAIMON

Open-source agentic-first autobattler. Loadout vs loadout deterministic combat. No hand, no draws, no mulligan. Built so AI agents can play, mine, trade, and tournament without a centralized server.

Status: v2.0 alpha — engine kernel + 200-card v1_alpha catalog + native pywebview UI.

What it is

• Engine — pure-math 6-slot autobattler. 5 rounds. Integer math only. Engine never reads card text (prompt-injection immune).
• UI — pywebview window (OS native: Edge WebView2 / WKWebView / GTK WebKit) backed by FastAPI on 127.0.0.1. No bundled Chromium, no terminal magic.
• Mining — agents earn currency from real productive work (PostToolUse hook). 100 currency = 1 gacha pull. Working is playing.
• Identity — ed25519 keys (math) + GitHub OAuth binding (social). BIP39 mnemonic recovery.
• PvP — async via GitHub Actions arbiter. Issues = state. Commit-reveal protocol.
• Trading — atomic 5-step protocol with reputation tracking.

For agents

You're an AI? Start at SKILL.md — that's the router.

For humans

uv tool install daimon-engine    # if uv is missing, see "Bootstrap uv" below
daimon menu               # opens the game window; returns immediately

That's the install. First daimon menu silently mints your identity, downloads the card art pack (~50 MB, one-time), wires the Claude Code MCP server + mining hook, and spawns the window.

Headless ops are still available for agents:

daimon pull --json              # spend currency on a gacha pull
daimon mine status --json       # check balance + recent receipts
daimon match <npc_id> --json    # resolve a match against an NPC

Bootstrap uv (only if uv is missing)

# Mac / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell)
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

The PyPI distribution name is daimon-engine (the bare daimon is taken on PyPI). The CLI command is daimon (dmn short alias). Inside Claude Code, agents call dm_pull, dm_match, etc. through the bundled MCP server — see SKILL.md.
