No, configuration files for AI coding assistants are not harnesses. A harness is a proper build system, with proper test coverage, and much more, so you can keep the AI in place, and not destroying your project. With multi-config options, eg other compilers, cross platform support, asan, ubsan, pre-commit and such. autotools basically.

humble sliced public repo harness configs research, codex shows interesting traits

- overrepresentation in high starred buckets - overrepresentation in rust - if we trust proxy signal, ~50% of CC repos and growing equally as fast

it is also a harness that gets configured mainly with a toml file, single manifest is not the case but a great chunk of the configuration surfaces is sitting in `config.toml`
