Investigate an OP Stack fault dispute game during (or after) an incident — answer the user's questions and diagnose: why a challenger is disagreeing, doing a lot of moves, or contradicting itself; whether a proposal is valid; which op-node is at fault; and (after the fact) who wins the bonds. Read-only.

Update the pinned upstream reth dependency across the Rust workspaces — pin bump, shared dependency sync, compile-and-adapt loop, full verification, and PR. Use when asked to bump, update, or upgrade reth (e.g. "update to reth v2.4.0").

Build dependencies and run acceptance tests locally in the Optimism monorepo. Handles contracts, cannon prestates, Rust binaries, and optional kona prestate.

Mark one or more superchain-ops tasks as EXECUTED by updating each task README's Status line to link the on-chain execution transaction, then open a PR. Use when a task (or batch of tasks) has been executed on-chain and someone shares the execution tx hash(es).

Diagnose and fix a failing `check_superchain_registry` CircleCI job on superchain-ops, typically caused by the pinned lib/superchain-registry submodule drifting from upstream main.

Integrate the Optimism Actions SDK into a TypeScript application. Handles wallet provider setup (Privy, Turnkey, Dynamic), DeFi provider configuration (Morpho, Aave lending), chain and asset selection, and smart wallet creation. Use when the developer wants to add DeFi capabilities like lending, borrowing, swaps, or payments to their app.

Invoke the Actions SDK from the shell - query assets/chains, derive an EOA address from a PRIVATE_KEY env var, read balances. Use when an agent needs to interact with the Actions SDK without embedding TypeScript.
