Lab 2A — Built-in tool loop

Use this lab’s provider.env.example and the preflight in a disposable workspace. Create service.txt with printf 'demo-order: Go; port 3000; queue orders-demo\n' > "$workdir/service.txt".

Run copilot -C "$workdir" -i "Read service.txt and report name, language, port and queue with a file citation. Do not modify files.". Approve only the required read. Compare to a new empty directory with the same request. Inspect which tool actually read the file and compare the citation with service.txt. Do not deliberately enable unrestricted shell execution as in build-your-own Lab 2A; the native loop already pairs calls and results, and its internal transcript is not ours. Record the observed tool and any unavailable internal details.
