agents-md provides non-working command in AGENTS.md instructions

[emonty]

Link to the code that reproduces this issue

https://github.com/emonty/next.js

To Reproduce

Run npx @next/codemod agents-md --output AGENTS.md
Inspect the instruction added to AGENTS.md. Execute that command in a clean checkout as-if you are an agent in a sandbox:
npx @next/codemod agents-md --output AGENTS.md

Current vs. Expected behavior

I expect the agent being given the instruction to be able to re-run the instruction successfully.
