TI4 Rules Engine

A Pythonic, structured data engine for Twilight Imperium 4th Edition. Tracks game state, provides rule references, and calculates player options from a live AsyncTI4 Discord bot game.

Analyse a game in one command

No installation required — just uvx:

uvx --from ti4-rules-engine ti4-analyze <game_name>

Replace <game_name> with the name of your AsyncTI4 game (the identifier shown by the bot, e.g. pbd22295):

uvx --from ti4-rules-engine ti4-analyze pbd22295

The command fetches the live game snapshot from the AsyncTI4 API and prints:

• Current round, phase, and active player
• Per-player summary: faction, VP, resources, planets, technologies, and leaders
• Every legal action available to each player under TI4 rules right now
• Reachable systems for each fleet (movement + anomaly rules applied)

Note: uvx --from ti4-rules-engine requires the package to be published on PyPI. Until then, clone the repo and use the local install instead:

git clone https://github.com/adam133/ti4-rules-engine
cd ti4-rules-engine
uv tool install .
ti4-analyze pbd22295
