Fork a warp route from the local HTTP registry for development and testing. Forks each chain with the right local node per protocol — anvil for EVM chains, surfpool (Solana mainnet fork) for Sealevel chains. Use when the goal is to simulate transactions on a set of local forks before submitting them on-chain.

Fork a warp route using the local HTTP registry.
Instructions:
Check if http://localhost:3333 is running. If not, run the start-http-registry SKILL. If that fails, ask the user to prompt the user for an alternate registry URL to use instead of http://localhost:3333.
First, ask the user to prompt the user for the warp route ID:
Run the command in the background:
pnpm -C typescript/cli exec tsx cli.ts warp fork --registry $REGISTRY --warpRouteId $WARP_ROUTE_ID
http://localhost:3333 by default, or user-provided if the local registry failed)run_in_background: true so it doesn't block the conversation.After starting, report the task/shell ID and the fork registry server port back to the user.
Remind the user they can stop it later with KillShell using that ID
Prerequisites:
/start-http-registry.anvil on PATH; Sealevel chains need a locally-installed surfpool binary (>= 1.5.0) on PATH — there is no Docker fallback in the CLI. Install the pinned, checksum-verified surfpool release the way CI does — see the Install surfpool step in .github/workflows/test-cli-e2e.yml (a pinned v1.5.0 release tarball verified against its SHA-256); do not pipe the mutable run.surfpool.run installer to a shell. If the binary is missing, warp fork aborts with a "surfpool 1.5.0+ is required" error before forking.Related skills:

Started warp fork for
EZETH/ethereum-megaethin background (shell ID:shell_abc123). To stop it later, I can use KillShell with that ID.

Write a changeset file in the `hyperlane-registry` repo for a PR that adds, updates, or modifies warp route config / chain metadata / addresses. Canonical pattern — never run the interactive `pnpm changeset` CLI; write the file directly. Referenced by any skill that opens a registry PR.

The low-level on-chain probes for identifying what an owner address is — cast code → EOA / EIP-7702-delegated EOA / contract, VERSION() → Gnosis Safe, read-only get-owner-ica.ts derive → ICA derivation, getAccountInfo → Sealevel account existence — with how to interpret each result. The primitive layer beneath validate-owners / resolve-artifacts / update-owners, which each apply their own per-chain or per-artifact policy on top.
