ethereum-optimism Dispute Game Investigator
When to Use
- During an incident, to answer questions and diagnose: a challenger disagreeing with a proposal or another challenger, performing many moves, or contradicting itself; whether the in-progress proposals are valid; which op-node is responsible.
- After the fact, for specifics like the bond outcome.
How to use it
Answer the user's actual question using only the relevant parts of the guide — you do
not need to run every step. Triage first (which game(s)? whose node? valid or not?) and pull
in only what bears on the question; some parts are situational (e.g. the bond outcome in §7 is
usually a post-incident question, not live triage). For a full end-to-end written analysis,
use the dispute-game-investigator agent instead.
Read-only: investigate and explain; never make moves, resolve, fund, or restart a challenger.
