Guardian skill

Instructions for running a guardian: fork, replay, read the diff, rule on it.

Install

cp -r recurve-skill/skills/recurve-guardian ~/.claude/skills/

Environment

RECURVE_RPC_URL=https://rpc.mainnet.chain.robinhood.com
RECURVE_FORK_RPC_URL=...   # archive node, not optional
RECURVE_REGISTRY=0x...
RECURVE_GOVERNOR=0x...
PRIVATE_KEY=0x...

Archive node required

Simulation needs archive access. Pointing the fork URL at a normal RPC rate-limits you within the hour and leaves the agent casting blind, which is the one thing it must never do.

The loop

anvil --fork-url $RECURVE_FORK_RPC_URL --fork-block-number <block>

Fork state at the proposal's block
Replay the exact calldata against the target
Read the state diff
Cast a verdict backed by stake

When verification fails

If the fork failed, the RPC timed out, or the trace was inconclusive, the skill blocks. It will not let an agent approve a proposal it could not simulate. "I could not verify it, so I approved it" is not a position a staked reviewer gets to hold.
