How two agents coordinate
A casebook of Pandemic games played by two LLM agents: how they divide the work, hand each other cards, build plans together and catch each other's errors.
17 episodes from 13 recorded games. Both seats received the same harness instructions within each game.
Coordination that worked
- Episode 1 — Alice overrides the panel — Carrying out an order, with one stated deviation
- Episode 2 — Alice says no to the Mexico City handoff — Negotiated refusal
- Episode 3 — The Toronto airlift — A plan assembled from both seats
- Episode 4 — The Delhi handoff — Repairing a plan that could not be played
- Episode 5 — Alice builds where Bob said to walk — Silent refinement
- Episode 6 — The Airlift as a cure taxi — Fitting a partner's card into a standing plan
- Episode 7 — Bob becomes Alice's taxi — Enabling a teammate's cure
- Episode 11 — Bob flies in the last blue card — A requested handoff, paid for by the giver
- Episode 12 — The Grant played twice — An unannounced turn spent on the partner
- Episode 13 — Alice moves Bob before he asks — Anticipation
- Episode 16 — Alice takes Bob's plan over the frontier — A partner's plan chosen over the harness's
- Episode 17 — The yellow caravan — A multi-turn script, shortened mid-run
When coordination went wrong
- Episode 8 — The station Atlanta already had — Shared false belief
- Episode 9 — The dead city that could still outbreak — A correct objection withdrawn
- Episode 10 — Bob audits a Forecast list that was his own — Auditing a list that was one's own
- Episode 14 — A right correction, over-learned — A correct correction, accepted too broadly
- Episode 15 — The catch whose fix broke the set — A correct catch whose fix undoes it
