- Developers running scripts written by AI agents
- Worth noticing
- The example varies file, command, and network permissions while keeping the test-and-report script itself in view.
Field notes
The page holds a sample test-and-report script constant while varying its declared permissions: access to `./src`, permission to run `npm test` or `git push`, and network access to `api.github.com:443`. It also lists CLI commands for checking, explaining, producing a manifest, building, and running programs. Those capabilities are described on the homepage, which says the compiler runs today; the supplied evidence does not test them.
