name: warp-fork description: Fork a warp route from the local HTTP registry for development and testing. Use when the goal is try to simulate transactions on a set of anvil forks.

Warp Fork

Fork a warp route using the local HTTP registry.

Instructions:

1. Check if http://localhost:3333 is running. If not, run the start-http-registry SKILL. If that fails, use AskUserQuestion to prompt the user for an alternate registry URL to use instead of http://localhost:3333.

2. First, use AskUserQuestion to prompt the user for the warp route ID:

   • Question: "Which warp route would you like to fork?"
   • Header: "Warp Route"
   • Options: Provide 2-3 common examples if known, otherwise use generic placeholders. Note that the fork may fail if the warp routes are invalid. Re-prompt the user!

3. Run the command in the background:

   Copypnpm -C typescript/cli exec tsx cli.ts warp fork --registry $REGISTRY --warpRouteId $WARP_ROUTE_ID
   

   • Use the registry URL from step 0 for $REGISTRY (http://localhost:3333 by default, or user-provided if the local registry failed)
   • Use run_in_background: true so it doesn't block the conversation.

4. After starting, report the task/shell ID and the fork registry server port back to the user.

5. Remind the user they can stop it later with KillShell using that ID

Prerequisites:

• The http-registry server must be running on port 3333. If not, start it first with /start-http-registry.

Example output:

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