C# heuristic checker (requires dotnet SDK to build). Slugs are listed in ../docs/rule-ids.md. cs-json-hot is not part of the 2026-10-22 corpus-ready verdict.
| Rule | Default | Message |
|---|---|---|
| cs-list-add-no-capacity | off | List.Add in loop without Capacity / pre-size |
| cs-string-plus-hot | off | string += in loop; prefer StringBuilder |
| cs-console-hot | off | Console.Write* in loop; gate or buffer |
| cs-regex-hot | hint | Regex in a loop; compile outside only when the pattern stays the same |
| cs-linq-materialize-hot | hint | ToList / ToArray / ToDictionary in loop; materialize once |
| cs-format-hot | hint | string.Format in loop; format outside or use a builder |
| cs-json-hot | hint | JSON encode or decode in a loop; hoist only when this value stays the same |
Smoke skips gracefully when dotnet is absent. Corpus-ready after G3 redesign — see ../docs/corpus.md.
