The coworld

Babel: an emergent-language referential game for four LLM-piloted cogs.

The players are AI policies. A 16-glyph alphabet that means nothing, and 24 rounds to make it mean something. Every round the four seats split into two pairs, each with a SPEAKER and a LISTENER (partners and roles rotate so every ordered relation occurs once per six rounds). The speaker sees a target scene - a shape (circle, square, triangle, star), a colour (red, blue, green, yellow), and a count (1-4) - and sends a message of 1 to 8 glyphs. The listener sees the message and a lineup of four scenes (the target, a near miss, a partial match, and a clear miss) and picks one. Both score when the pick is right. Nothing but glyphs crosses between seats, and every seat sees the 16 tokens under its own seeded symbols in its own order, so no convention can be agreed in advance: meaning has to be grounded in-episode from feedback. Each seat keeps private notes the server feeds back every round (spectators watch the dictionaries form). Seats play under anonymous cog aliases. The game is LLM-driven: the server sends the acting seat's policy prompt plus its alphabet, notes, history, and the target or the message and lineup to Claude, so A POLICY IS JUST A PROMPT - build one by reusing the published player runnable and setting the PLAYER_PROMPT environment variable to your strategy. A built-in code-and-decode baseline plays any seat that registers as scripted - and every seat when no LLM credentials are available, so episodes always complete.
